hi everybody
i want to ask :
How to add a tab programmically.
for my problem
i have a tab control, as default only one tab. and i have a button when i click that button will add one other tab. so will be two tab.
please help me using c# and xaml.
tabControl.Items.Add(yourNewTabItem);
Try this way:
tabControl1.TabPages.Add("tab 3");
Some more code to create and modify tabPages manually:
public partial class Form1 : Form
{
TabControl tc;
public Form1()
{
InitializeComponent();
tc = new TabControl();
tc.TabPages.AddRange(new TabPage[]
{
new TabPage("tabPage 1"),
new TabPage("tabPage 2")
});
tc.Location = new Point(20, 20);
tc.Size = new Size(300, 200);
this.ClientSize = new Size(350, 250);
this.Controls.Add(tc);
//renaming:
this.tc.TabPages[0].Text = "1st tab";
this.tc.TabPages[1].Text = "2nd tab";
//changing background:
this.tc.TabPages[0].BackColor = Color.Yellow;
this.tc.TabPages[1].BackColor = Color.YellowGreen;
//adding some controls to each tab:
TextBox tb = new TextBox();
tb.Location = new Point(20, 20);
tb.Size = new Size(130, 20);
tb.Text = "This textBox is on 1st tab";
Label lb = new Label();
lb.Location = new Point(20, 20);
lb.Text = "This label is on 2nd tab";
lb.ForeColor = Color.Red;
this.tc.TabPages[0].Controls.Add(tb);
this.tc.TabPages[1].Controls.Add(lb);
}
}

Okay so basically I have a calendar display and when you click on anyone of the dates on it, it creates a new panel with a label displaying the date selected. I also made it so when you click on a date and a new panel is made, a label, textbox and button is created and placed onto that new panel as well.
So what I want and have been struggling with is for me to enter something into that textbox then to press the button to submit it and then for it to show on the label.
I think I know what the issue is but I've been stuck at this for hours.
Here is my code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void monthCalendar1_DateSelected_1(object sender, DateRangeEventArgs e)
{
Panel newPanel = new Panel();
this.Controls.Add(newPanel);
newPanel.Visible = true;
newPanel.Size = new Size(564, 831);
newPanel.Location = new Point(0, 190);
newPanel.BringToFront();
Label textLabel = new Label();
textLabel.Size = new Size(500, 500);
textLabel.Font = new Font(textLabel.Font.Name, 25, textLabel.Font.Style);
textLabel.Location = new Point(3, 3);
Label dateLabel = new Label();
dateLabel.Size = new Size(500, 500);
dateLabel.Font = new Font(dateLabel.Font.Name, 25, dateLabel.Font.Style);
dateLabel.Location = new Point(128, 3);
Button Submitbutton = new Button();
Submitbutton.Location = new Point(100, 500);
Submitbutton.Text = "Add Food";
Submitbutton.Size = new Size(400, 100);
Submitbutton.BackColor = Color.Aqua;
Submitbutton.BringToFront();
Submitbutton.Click += Button_Click;
TextBox textBox = new TextBox();
textBox.Location = new Point(100, 650);
textBox.Size = new Size(500, 500);
textBox.BackColor = Color.Aqua;
textBox.Visible = true;
textBox.Text = "Enter food here...";
textBox.BringToFront();
Label inputtedFood = new Label();
inputtedFood.Size = new Size(500, 500);
inputtedFood.Font = new Font(inputtedFood.Font.Name, 25, inputtedFood.Font.Style);
inputtedFood.Location = new Point(100, 600);
inputtedFood.Text = "placeholder";
newPanel.Controls.Add(dateLabel);
newPanel.Controls.Add(textLabel);
newPanel.Controls.Add(Submitbutton);
newPanel.Controls.Add(textBox);
newPanel.Controls.Add(inputtedFood);
String myCalendar = monthCalendar1.SelectionRange.Start.ToShortDateString();
textLabel.Text = "Date:";
dateLabel.Text = myCalendar;
}
private void Button_Click(object sender, EventArgs e)
{
inputtedFood.Text = textBox.Text;
}
private void monthCalendar1_DateChanged_1(object sender, DateRangeEventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
}
}
I tried the above code and was met with errors that are shown in the post.
Totally agree with both LarsTech and Ňɏssa Pøngjǣrdenlarp, you should be building a UserControl in place of the Panel and placing the TextBox, Button, and Label inside of that.
Your immediate question, though:
So what I want and have been struggling with is for me to enter
something into that textbox then to press the button to submit it and
then for it to show on the label.
Can be accomplished with this simple code:
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
Here's a little example showing it in action:
private void button1_Click(object sender, EventArgs e)
{
FlowLayoutPanel flp = new FlowLayoutPanel();
TextBox textBox = new TextBox();
// ... more code ...
Label inputtedFood = new Label();
inputtedFood.Text = "placeholder";
// ... more code ...
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
flp.Controls.Add(textBox);
flp.Controls.Add(Submitbutton);
flp.Controls.Add(inputtedFood);
flowLayoutPanel1.Controls.Add(flp);
}
The output:
I want to control my form load event from another form.
my problem I create some winform control in form1 runtime, but the creation will controlled by form2.
I will read some data from user in form2 and when user enter specific text I will create winform control in form1.
I make some code to do that using from1 to create winform control in runtime.
private TextBox txtBox = new TextBox();
private Button btnAdd = new Button();
private ListBox lstBox = new ListBox();
private CheckBox chkBox = new CheckBox();
private Label lblCount = new Label();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.MaximizeBox = false;
this.MinimizeBox = false;
this.BackColor = Color.White;
this.ForeColor = Color.Black;
this.Size = new System.Drawing.Size(550, 550);
this.Text = "Test Create form in runtime ";
this.FormBorderStyle = FormBorderStyle.FixedDialog;
this.StartPosition = FormStartPosition.CenterScreen;
this.btnAdd.BackColor = Color.Gray;
this.btnAdd.Text = "Add";
this.btnAdd.Location = new System.Drawing.Point(90, 25);
this.btnAdd.Size = new System.Drawing.Size(50, 25);
this.txtBox.Text = "Text";
this.txtBox.Location = new System.Drawing.Point(10, 25);
this.txtBox.Size = new System.Drawing.Size(70, 20);
this.lstBox.Items.Add("One");
this.lstBox.Sorted = true;
this.lstBox.Location = new System.Drawing.Point(10, 55);
this.lstBox.Size = new System.Drawing.Size(130, 95);
this.chkBox.Text = "Disable";
this.chkBox.Location = new System.Drawing.Point(15, 190);
this.chkBox.Size = new System.Drawing.Size(110, 30);
this.lblCount.Text = lstBox.Items.Count.ToString() + " items";
this.lblCount.Location = new System.Drawing.Point(55, 160);
this.lblCount.Size = new System.Drawing.Size(65, 15);
this.Controls.Add(btnAdd);
this.Controls.Add(txtBox);
this.Controls.Add(lstBox);
this.Controls.Add(chkBox);
this.Controls.Add(lblCount);
}
How make the same thing from form2 ?
I don't know which kind of 'Control' you need. However in multiple forms environment, communication between forms is trivial. There are many ways to do communicate, like one can be as
Create public properties of type Form in your Parent form,
public Form propForm1 {get;set;}
When on menu item click you open form1, store it's object to that public property.
var form1 = New yourchildformname();
form1.MdiParent = this;
propForm1 = form1; // Add this line.
form1.Show();
Now every time when you will click an other button to open the form2, you will have propForm1 object, which you can use to set some data on that form.
EDIT:
On form2, you can access controls of form1 as
private void button1_Click(object sender, EventArgs e)
{
this.parent.propForm1.txtUserName = "Yokohama";
}
Remember the above code is on form2. Also set 'access modifier' property of txtUserName from private to public.
I am currently working with c# and a flp.
My program uses a loop to add buttons like
I need a third button directly under the red one, to get a view like
Any ideas?
My code:
private void createButton(Entry e)
{
Button newButton = new Button();
newButton.Text = e.title;
newButton.BackColor = System.Drawing.Color.FromArgb(e.colorARGB);
//sizing
newButton.Size = new System.Drawing.Size(300, 60);
newButton.Font = new System.Drawing.Font(newButton.Font.FontFamily, 18);
newButton.Click += new EventHandler(newButton_Click);
newButton.ForeColor = System.Drawing.Color.FromArgb((int)InvertColor((uint)newButton.BackColor.ToArgb()));
newButton.Tag = Link_List.Count - 1;
m_fLPQuickboard.Controls.Add(newButton);
Button newButtonX = new Button();
newButtonX.Text = "X";
newButtonX.BackColor = System.Drawing.Color.FromName("Red");
newButtonX.Size = new System.Drawing.Size(30, 30);
newButtonX.Click += new EventHandler(newButtonX_Click);
newButtonX.Tag = Link_List.Count - 1;
//Tooltips
ToolTip newButtonTooltip = new ToolTip();
newButtonTooltip.SetToolTip(newButton, getParameterFileAsTooltip(e.path));
}
I am trying to create a windows application where I want to display a group of controls (Combo Box, Text Box and a button) on button click inside a panel.
I have created a code to create controls once but I want to create them again and again on button click one below another.
The code I am using is
public partial class Employee_PayHeads_add : Form
{
private TextBox txtBox = new TextBox();
private Button btnAdd = new Button();
private ComboBox combohead = new ComboBox();
public Employee_PayHeads_add()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.btnAdd.BackColor = Color.Gray;
this.btnAdd.Text = "Remove";
this.btnAdd.Location = new System.Drawing.Point(240, 25);
this.btnAdd.Size = new System.Drawing.Size(70, 25);
this.txtBox.Text = "";
this.txtBox.Location = new System.Drawing.Point(150, 25);
this.txtBox.Size = new System.Drawing.Size(70, 40);
this.combohead.Location = new System.Drawing.Point(10, 25);
panel1.Controls.Add(btnAdd);
panel1.Controls.Add(txtBox);
panel1.Controls.Add(combohead);
}
Also I want a vertical scroller in the panel if number controls overlap the space.
Thanks in advance
Inside the button click event create new objects, instead of using the one you declared before.
Try something like that:
public partial class Employee_PayHeads_add : Form
{
private TextBox txtBox = new TextBox();
private Button btnAdd = new Button();
private ComboBox combohead = new ComboBox();
private int txtBoxStartPosition = 150;
private int btnAddStartPosition = 240;
private int comboheadStartPosition = 10;
}
public Employee_PayHeads_add()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
TextBox newTxtBox = new TextBox();
Button newBtnAdd = new Button();
ComboBox newCombohead = new ComboBox();
newBtnAdd.BackColor = Color.Gray;
newBtnAdd.Text = "Remove";
newBtnAdd.Location = new System.Drawing.Point(btnAddStartPosition, 25);
newBtnAdd.Size = new System.Drawing.Size(70, 25);
newTxtBox.Text = "";
newTxtBox.Location = new System.Drawing.Point(txtBoxStartPosition, 25);
newTxtBox.Size = new System.Drawing.Size(70, 40);
newCombohead.Location = new System.Drawing.Point(comboheadStartPosition, 25);
panel1.Controls.Add(newBtnAdd);
panel1.Controls.Add(newTxtBox);
panel1.Controls.Add(newCombohead);
txtBoxStartPosition += 50;
btnAddStartPosition += 50;
comboheadStartPosition += 50;
}
I havent tried your code yet, but it shows that it is always creating the new controls on every click event, but as youo have specified the hardcoaded location for buttons, so it must be creating new controls overlapping each other. so you can change the location dynamically and hopefully it will work
If you want to add the controls again and again you have to create new ones. So rather than defining them in your form like that you have to:
private void button1_Click(object sender, EventArgs e)
{
Button btnAdd = new Button();
btnAdd.BackColor = Color.Gray;
btnAdd.Text = "Remove";
btnAdd.Location = new System.Drawing.Point(240, 25);
btnAdd.Size = new System.Drawing.Size(70, 25);
TextBox txtBox = new TextBox();
txtBox.Text = "";
txtBox.Location = new System.Drawing.Point(150, 25);
txtBox.Size = new System.Drawing.Size(70, 40);
ComboBox combohead = new ComboBox();
combohead.Location = new System.Drawing.Point(10, 25);
panel1.Controls.Add(btnAdd);
panel1.Controls.Add(txtBox);
panel1.Controls.Add(combohead);
}
Now you can remove those private declarations on top of your class.
I have the below code. I think I have pretty close to what I need. There is a main tab at startout (which does not contain tb, tb1, tb2, and tb3. Once I click the button, a tab is generated containing tb, tb1, tb2, tb3.
tb, tb1,tb2, and tb3 show errors of not existing. I simply cannot figure out how to get these saved.
public partial class Form1 : Form

public string status = "no";

You need to store tb1, etc in fields in your form so they can be accessed by other methods.
tb, tb1,tb2, and tb3 show errors of not existing.
Yes, they would - you're declaring them as local variables within button1_Click. To access them from other methods, you'll either need to just examine the controls within the tab page, or declare them as instance variables instead. However, in that case you'd need to consider the fact that there may be multiple tab pages.
It sounds like you really just need to iterate over the controls within each tab page, and pick out the textboxes. Either that, or perhaps create your own subclass of TabPage which knows about the textboxes. Then you could find each instance of your custom TabPage and ask it to save itself.
