Where do I put these visible changes for them to display - c#

I have my code written like so:
private void radioSelectButton_Click(object sender, EventArgs e)
{
if (pteriRadio.Checked) // Selecting avatar to be displayed from here on out.
//This avatar will also be displayed on the game board.
{
pteriBox1.Visible = true;
xweetokBox1.Visible = false;
ixiBox1.Visible = false;
label1.Text = ("Pteri Inventory");
player1avatar = "pteri";
}
else if (xweetokRadio.Checked)
{
xweetokBox1.Visible = true;
pteriBox1.Visible = false;
ixiBox1.Visible = false;
label1.Text = ("Xweetok Inventory");
player1avatar = "xweetok";
}
else if (ixiRadio.Checked)
{
ixiBox1.Visible = true;
pteriBox1.Visible = false;
xweetokBox1.Visible = false;
label1.Text = ("Ixi Inventory");
player1avatar = "ixi";
}
characterSelectBox.Visible = false;
radioSelectButton.Visible = false;
characterSelectBox2.Visible = true;
radioSelectButton2.Visible = true;
}
It seems as though the visibility changes should display when I have it like this, with the changes within the button click but outside of the if statements (It doesn't matter what the user selects, once selected the option to select needs to disappear for that user.)Yet the visibility changes don't execute. What am I missing here?
If I nest the if-statements as suggested by a previous person, here's what I have:
private void radioSelectButton_Click(object sender, EventArgs e)
{
if (pteriRadio.Checked) // Selecting avatar to be displayed from here on out.
//This avatar will also be displayed on the game board.
{
pteriBox1.Visible = true;
xweetokBox1.Visible = false;
ixiBox1.Visible = false;
label1.Text = ("Pteri Inventory");
player1avatar = "pteri";
if (xweetokRadio.Checked)
{
xweetokBox1.Visible = true;
pteriBox1.Visible = false;
ixiBox1.Visible = false;
label1.Text = ("Xweetok Inventory");
player1avatar = "xweetok";
if (ixiRadio.Checked)
{
ixiBox1.Visible = true;
pteriBox1.Visible = false;
xweetokBox1.Visible = false;
label1.Text = ("Ixi Inventory");
player1avatar = "ixi";
}
characterSelectBox.Visible = false;
radioSelectButton.Visible = false;
characterSelectBox2.Visible = true;
radioSelectButton2.Visible = true;
}
}
}
Now, not only do the visible items not swap over, two of the character choices don't display.

It looks like the radio buttons here can be checked/unchecked together. I think you should use separate if statements for each condition instead of else if.

You need to Invalidate your form to make it redraw after you change the properties. Assuming the radioSelectButton_Click method is in the same form, calling this.Invalidate() at the end of the method should force the redraw.

How do i get an information label to appear as i type and disappear when i delete the text

I have a couple of text boxes that i have initially hidden and what I want to do is as the users type I would like the next text box along with the label that goes with it to appear to notify of the next question.
At the same time if they change their mind and delete their response to the first question the next text box and label will disappear once the text has been deleted.
Here is my current code:
private void CreditScoreBox_KeyPress(object sender, KeyPressEventArgs e)
{
if (char.IsControl(e.KeyChar) || char.IsDigit(e.KeyChar))
e.Handled = false;
else
e.Handled = true;
if(CreditScoreBox.Text == "")
{
MakeBox.Visible = false;
MakeLabel.Visible = false;
ModelBox.Visible = false;
ModelLabel.Visible = false;
CreditLevelLabel.Visible = false;
}
else
{
MakeBox.Visible = true;
MakeBox.Enabled = true;
MakeLabel.Visible = true;
CreditLevelLabel.Visible = true;
}
I have tried using the TextChanged event with the same result.
I created a Form, with 2 textbox and 1 label. If text exist in textbox1 then label1 and textbox2 become available:
private void textBox1_TextChanged(object sender, EventArgs e)
{
if (textBox1.Text == "")
{
textBox2.Enabled = false;
textBox2.Visible = false;
label1.Visible = false;
}
else
{
textBox2.Enabled = true;
textBox2.Visible = true;
label1.Visible = true;
}
}

How To Make A Child Execute Command Button in C#

i having a little advance with Command Button
lets say i having a form with
label1
label2
label3
And one command button of course
before click the command button
label1.Visible = true;
label2.Visible = false;
label3.Visible = false;
if i click the command button
label1.Visible = false;
label2.Visible = true;
label3.Visible = false;
and then i click again
label1.Visible = false;
label2.Visible = false;
label3.Visible = true;
and repeated again, then back to first before i click the command button
i didnt have any reference on this, so i just make a duplicated command button with same position in form, and i use the visible to get the another command button to be clicked
but it looks not cool,
is there any way better than i make?
you can make one button, and count the number of clicks the user has done, depending on the mod operation you can invoke any of the three method you provide, something like this:
int count = 1; //count clicks
private void ButtonClick(object sender, EventArgs e)
{
if(count%2 == 0)
{
label1.Visible = false;
label2.Visible = true;
label3.Visible = false;
}
else if(count%3 == 0){
label1.Visible = false;
label2.Visible = false;
label3.Visible = true;
}
else{
label1.Visible = true;
label2.Visible = false;
label3.Visible = false;
}
count++;
}
Something similar to this will allow you to only have one command button.
public int visibleLabel = 1;
private void commandButton_Click(object sender, EventArgs e)
{
this.visibleLabel += 1;
if (this.visibleLabel == 4) this.visibleLabel = 1
label1.visble = false;
label2.visble = false;
label3.visble = false;
switch (this.visibleLabel)
{
case 1:
label1.visble = true;
break;
case 2:
label2.visble = true;
break;
case 3:
label3.visble = true;
break;
}
}
Alternatively, you might want to consider having a single label and changing the text (assuming they are in the same locations as well)
Why dont you use a flag to track the current status of the command button? If I understand your question right you want a single command button that sets label2 to visible at first click and label3 visible at second click and label1 visible on third click. Do something like this in the command button click handler:
switch (status)
{
case 0:
{
label1.Visible = false;
label2.Visible = true;
label3.Visible = false;
status = 1;
break;
}
case 1:
{
label1.Visible = false;
label2.Visible = false;
label3.Visible = true;
status = 2;
break;
}
case 2:
{
label1.Visible = true;
label2.Visible = false;
label3.Visible = false;
status = 0;
break;
}
}
Some of the code is redundant, and of course you should have a integer variable called status somewhere in your class. Anyway, this should be fairly understandable and I hope it helps.

GO Properties window and change "Icon" property with your own icon.
You need to perform following steps
Add you icon to resouce file of project
than Asssing the created resource to you icon property .
Icon = Resources.adobe_reader_icon;
You have to set it in the properties of your project.
If you start your application by pressing F5 in VisualStudio and the icon doesn't appear, take a look in the Debug-(Release) Directory. There should be the correct icon
The icon of a form is only displayed if:
- ControlBox is true
- FormBorderStyle is not None
- Text is not empty
If so, you should then be able to set it with this.Icon = ...
Also the icon should be available as project resource. For this, you can just edit the forms Icon property, and in the following dialog import the icon from a .ico file.
<pre>
application root directory
application resources directory **LIKE** ../../resources/dropbox.ico
this.Icon = new System.Drawing.Icon("../../dropbox.ico");
</pre>
First Solution then Properties of the project Add .ico file
Then open Form which you want icon
In Form property you can find Icon Field
There you can change Icon your windows form.

RadioButtonList: OnSelectedIndexChanged not firing

I have an aspx page where i dynamically add a radiobuttonlist with OnSelectedIndexChanged event. In the event i check for the selected items. i have 2 items.
For the first item,the event is firing well, However if i choose the other option the event is not firing: below the code..
The event is only firing is i change from "Some provided" to "All provided" the other way it is not working
Adding the RBL:
RadioButtonList dControl_b = new RadioButtonList();
dControl_b.ID = "rbl_MinCriteria";
dControl_b.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;
dControl_b.CssClass = "Font";
dControl_b.Font.Name = "Arial";
dControl_b.Font.Size = 8;
dControl_b.ToolTip = "";
dControl_b.SelectedIndex = -1;
dControl_b.SelectedIndexChanged += new EventHandler(rbl_MinCriteria_SelectedIndexChanged);
dControl_b.AutoPostBack = true;
Checking the selected item:
if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
{
cbl_MinimumCriteria.Items[0].Selected = true;
cbl_MinimumCriteria.Items[1].Selected = true;
cbl_MinimumCriteria.Items[2].Selected = true;
cbl_MinimumCriteria.Items[3].Selected = true;
cbl_MinimumCriteria.Enabled = false;
//*************************************************************
if (ddl_CountryOccurence.SelectedValue != "Please choose")
{
ddl_CountryOccurence.Enabled = false;
}
else
{
ddl_CountryOccurence.Enabled = true;
}
//*************************************************************
if (tb_DueDate.Text != "")
{
tb_DueDate.Enabled = false;
}
else
{
tb_DueDate.Enabled = true;
}
OtherControlI.Enabled = false;
OtherControlII.Enabled = false;
OtherControlIII.Enabled = false;
}
if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
{
cbl_MinimumCriteria.Items[0].Selected = false;
cbl_MinimumCriteria.Items[1].Selected = false;
cbl_MinimumCriteria.Items[2].Selected = false;
cbl_MinimumCriteria.Items[3].Selected = false;
cbl_MinimumCriteria.Enabled = true;
//*************************************************************
if (ddl_CountryOccurence.SelectedValue != "Please choose")
{
ddl_CountryOccurence.Enabled = false;
}
else
{
ddl_CountryOccurence.Enabled = true;
}
//*************************************************************
if (tb_DueDate.Text != "")
{
tb_DueDate.Enabled = false;
}
else
{
tb_DueDate.Enabled = true;
}
OtherControlI.Enabled = false;
OtherControlI.SelectedIndex = -1;
OtherControlII.Enabled = false;
OtherControlII.SelectedIndex = -1;
OtherControlIII.Enabled = false;
OtherControlIII.SelectedIndex = -1;
}
Any help and Comment is much appreciated
This is for people who find this question from Google:
On the RadioButtonList, set the AutoPostBack property to true.
RadioButtonList OnSelectedIndexChanged
I have this problem and solved it.
For raising onselectedindexchanged event of RadioButtonList , check below items:
<asp:RadioButtonList ID="rdlCondition" runat="server" AutoPostBack="True"
onselectedindexchanged="rdlCondition_SelectedIndexChanged">
and in the Page_Load set them with code :
rdlCondition.AutoPostBack = true;
rdlCondition.SelectedIndexChanged += new EventHandler (rdlCondition_SelectedIndexChanged);
Looking at the code above there seems to be alot of code reuse. I reorganized your code a bit (assuming you didnt leave anything out). Keep in mind I never tested it.
protected void rbl_MinCriteria_SelectedIndexChanged(object sender,EventArgs e)
{
if (rbl_MinCriteria.SelectedIndex<0) return; //If nothing is selected then do nothing
OtherControlI.Enabled = false;
OtherControlII.Enabled = false;
OtherControlIII.Enabled = false;
if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
{
cbl_MinimumCriteria.Items[0].Selected = true;
cbl_MinimumCriteria.Items[1].Selected = true;
cbl_MinimumCriteria.Items[2].Selected = true;
cbl_MinimumCriteria.Items[3].Selected = true;
cbl_MinimumCriteria.Enabled = false;
}
if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
{
cbl_MinimumCriteria.Items[0].Selected = false;
cbl_MinimumCriteria.Items[1].Selected = false;
cbl_MinimumCriteria.Items[2].Selected = false;
cbl_MinimumCriteria.Items[3].Selected = false;
cbl_MinimumCriteria.Enabled = true;
OtherControlI.SelectedIndex = -1;
OtherControlII.SelectedIndex = -1;
OtherControlIII.SelectedIndex = -1;
}
//*************************************************************
if (ddl_CountryOccurence.SelectedValue != "Please choose")
{
ddl_CountryOccurence.Enabled = false;
}
else
{
ddl_CountryOccurence.Enabled = true;
}
//*************************************************************
if (tb_DueDate.Text != "")
{
tb_DueDate.Enabled = false;
}
else
{
tb_DueDate.Enabled = true;
}
}
I know this doesn't help your current problem but this is just a suggestion. If you could post the code where your actually adding the values to the list I could help a bit more.
EDIT: Your problem could be your not setting the value of your items, only the text. Try using rbl_MinCriteria.SelectedItem.Text =="All provided" instead.
I've made a sample aspx page, and added one panel in .aspx like below:
<asp:Panel ID="Panel1" runat="server"></asp:Panel>
And in code behind, I've added following code:
protected void Page_Load(object sender, EventArgs e)
{
RadioButtonList dControl_b = new RadioButtonList();
dControl_b.ID = "rbl_MinCriteria";
dControl_b.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;
dControl_b.CssClass = "Font";
dControl_b.Font.Name = "Arial";
dControl_b.Font.Size = 8;
dControl_b.ToolTip = "";
dControl_b.SelectedIndex = -1;
dControl_b.SelectedIndexChanged += new EventHandler(rbl_MinCriteria_SelectedIndexChanged);
dControl_b.AutoPostBack = true;
dControl_b.Items.Add(new ListItem("All provided"));
dControl_b.Items.Add(new ListItem("Some provided"));
Panel1.Controls.Add(dControl_b);
}
protected void rbl_MinCriteria_SelectedIndexChanged(object sender,EventArgs e)
{
RadioButtonList rbl_MinCriteria = (RadioButtonList)Panel1.FindControl("rbl_MinCriteria");
if(rbl_MinCriteria.SelectedItem.ToString() == "All provided")
{
}
if (rbl_MinCriteria.SelectedItem.ToString() == "Some provided")
{
}
}
The event is FIRING EVERY TIME the radio button listitem is changed.
So, I'm afraid, you have done something wrong elsewhere. Good luck.

Object not set to instance....blah

i have radio buttons that autopostback and set panels to either visible or invisible. The entire page is in an update panel so that i can force it to update and show the invisible changes. The radio buttons are also in update panels.
It works fine except for one thing - my javascript went out the window! It can't find any of my controls after the panel is updated.
Is there some way i can fix this?
Panel PnlPersonInjury = (Panel)FormView1.FindControl("PnlPersonInjury");
Panel pnlPropertyDamage = (Panel)FormView1.FindControl("pnlPropertyDamage");
RadioButton CTypeP = (RadioButton)FormView1.FindControl("RadioButton1");
RadioButton CTypeC = (RadioButton)FormView1.FindControl("RadioButton2");
RadioButton LossLossP = (RadioButton)FormView1.FindControl("RadioButton3");
RadioButton LossLossI = (RadioButton)FormView1.FindControl("RadioButton4");
if (LossLossI.Checked)
{
// pnlPropertyDamage.Enabled = false;
PnlPersonInjury.Enabled = true;
PnlPersonInjury.Visible = true;
pnlPropertyDamage.Visible = false;
InjSummmary.Visible = false;
PropSummary.Visible = false;
}
else
{
pnlPropertyDamage.Enabled = true;
PnlPersonInjury.Enabled = false;
PnlPersonInjury.Visible = false;
pnlPropertyDamage.Visible = true;
InjSummmary.Visible = false;
PropSummary.Visible = false;
}
if (CTypeC.Checked)
{
cPanel.Enabled = true;
pPanel.Enabled = false;
cPanel.Visible = true;
pPanel.Visible = false;
}
else
{
cPanel.Enabled = false;
pPanel.Enabled = true;
cPanel.Visible = false;
pPanel.Visible = true;
}
UpdatePanel20.Update();
UpdatePanel2.Update();
I left some of the instantiation of some controls out - so that is not an issue.
Without seeing the JavaScript, or knowing what part of this code is related to the error, I'd guess that this line is part of your problem:
PnlPersonInjury.Visible = false;
If a server-side control is hidden, it doesn't render anything to the client-side markup.
