I have set the label text as empty as it depend on the situation.
In ascx file I set as below code:
<td runat="server" id="tdAvailableD" class="text-center" style ="font-size: 12px">
<asp:Label ID="lblAvailable" runat="server" ForeColor="Red" Visible="true" Text=""></asp:Label></td>
In ascx.cs file I set as below code:
private void CheckQuantityError()
{
for (int i = 0; i < dlDiscountedProducts.Items.Count; i++)
{
{
DropDownList qty = (DropDownList)dlDiscountedProducts.Items[i].FindControl("ddlQuantity");
HiddenField productId = (HiddenField)dlDiscountedProducts.Items[i].FindControl("hdnProductID");
HiddenField discountRuleId = (HiddenField)dlDiscountedProducts.Items[i].FindControl("hdnDiscountRuleId");
//HiddenField AvailStatus = (HiddenField)dlDiscountedProducts.Items[i].FindControl("hdnAvailStatus");
//HtmlGenericControl spanAvailStatus = (HtmlGenericControl)dlDiscountedProducts.Items[i].FindControl("spanAvailStatus");
Label lblOutofStockError = (Label)dlDiscountedProducts.Items[i].FindControl("lblOutofStockError");
Label lblAvailable = (Label)dlDiscountedProducts.Items[i].FindControl("lblAvailable");
DCShoppingCartItem shoppingCartItem = new DCShoppingCartItem();
if (null != Product)
{
bool status = false;
try
{
using (new AcsServiceContextScope())
{
status = AcsServiceContextScope.Current.Products.GetAxStockAvailability(new GetStockAvailabilityRequest()
{
ModelNumber = Product.ModelNumber,
Quantity = 1,
ProductId = Product.Id
}).StockStatus;
}
}
catch (Exception ex)
{
Logging.EventLogger.LogEvent(ex);
}
if (status == true)
{
//spanAvailStatus.Attributes["class"] = "glyphicon glyphicon-remove";//available
lblAvailable.Visible = true;
lblAvailable.Text = "In Stock";
lblOutofStockError.Visible = true;
lblAlert.Visible = true;
}
else
{
//spanAvailStatus.Attributes["class"] = "glyphicon glyphicon-ok";//not available
lblAvailable.Visible = true;
lblAvailable.Text = "No Stock";
lblOutofStockError.Visible = true;
lblAlert.Visible = true;
//qty.BackColor = System.Drawing.Color.Yellow;
}
}
}
}
}
but the text not display in page.The function should show, if the item have quantity then it will show in stock.
Try keeping lblAvailable inside an update panel and try posting back the page.
The reason could be setting the text in label is not posted back to the page.
Check if the value is Coming to the lblAvailable properly.
If it is? then put the
<asp:UpdatePanel ID="UpdatePanel" runat="server">
<ContentTemplate>
<td runat="server" id="tdAvailableD" class="text-center" style ="font-size: 12px">
<asp:Label ID="lblAvailable" runat="server" ForeColor="Red" Visible="true" Text=""></asp:Label></td>
</ContentTemplate>
</asp:UpdatePanel>
then in .cs use this
UpdatePanel.Update();
and remove Text and ForeColor properties rather do it from .cs
u can even give different colors
lblAvailable.ForeColor = System.Drawing.Color.Green;//or red when not in stock

Put this in the page directive <%# Page %>
MaintainScrollPositionOnPostback = "true"
It happens due to page PostBack. The above ensures the position of the scroll after page PostBack.
Or keep the GridView in a div and use JavaScript trick to do so: Maintain Scroll Position in Div
I am trying to create a simple form generating webpage that user can select different controls via a DropDownList, add a Text property to it(and a GroupName property if ii was a RadioButton) and then click a button to generate that control right in the page for previewing purpose (I am also going to add another button to insert the form's information in a database but this is not my problem right now)
this is my aspx page:
<div class="main-wrapper">
<form dir="rtl" id="form" runat="server">
<label>Desired Control : </label>
<asp:DropDownList AutoPostBack="true" ID="ddlControlType" OnSelectedIndexChanged="ddlControlType_SelectedIndexChanged" runat="server">
<asp:ListItem Text="label"></asp:ListItem>
<asp:ListItem Text="text box"></asp:ListItem>
<asp:ListItem Text="check box"></asp:ListItem>
<asp:ListItem Text="radio button"></asp:ListItem>
</asp:DropDownList>
<br /><br />
<label class="label">control's text : </label>
<asp:TextBox ID="txtboxText" runat="server" CssClass="txtbox"></asp:TextBox>
<label class="label">group name (only for radio button)</label>
<asp:TextBox Enabled="false" ID="txtboxGroupName" runat="server" CssClass="txtbox"></asp:TextBox>
<br /><br />
<asp:Button ID="btnAddControl" CssClass="btn" Text="add to form" OnClick="btnAddControl_Click" runat="server" />
<hr />
<h1>form preview</h1>
<asp:Panel ID="panel" runat="server">
</asp:Panel>
</form>
this is the code behind:
public Dictionary<string, Type> ControlTypes
{
get { return (Dictionary<string, Type>)Session["ControlTypes"]; }
set { Session["ControlTypes"] = value; }
}
public int NumberOfControls
{
get { return (int)ViewState["NumOfControls"]; }
set { ViewState["NumOfControls"] = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
this.NumberOfControls = 0;
ControlTypes = new Dictionary<string, Type>();
}
else
this.CreateControls();
}
private void CreateControls()
{
for (int counter = 0; counter < this.NumberOfControls; counter++)
{
string controlId = "control_id_" + counter.ToString();
Type controlType = ControlTypes[controlId];
PropertyInfo[] properties = controlType.GetProperties();
object controlObject = Activator.CreateInstance(controlType);
foreach (var property in properties)
{
if (property.Name == "ID")
property.SetValue(controlObject, controlId, null);
}
panel.Controls.Add(controlObject as Control);
}
}
protected void ddlControlType_SelectedIndexChanged(object sender, EventArgs e)
{
switch (ddlControlType.SelectedIndex)
{
case 0:
case 2:
txtboxText.Enabled = true;
txtboxGroupName.Enabled = false;
break;
case 1:
txtboxText.Enabled = false;
txtboxGroupName.Enabled = false;
break;
case 3:
txtboxText.Enabled = true;
txtboxGroupName.Enabled = true;
break;
}
}
protected void btnAddControl_Click(object sender, EventArgs e)
{
Control tempControl = null;
switch (ddlControlType.SelectedIndex)
{
case 0:
tempControl = new Label();
((Label)tempControl).Text = txtboxText.Text;
break;
case 1:
tempControl = new TextBox();
break;
case 2:
tempControl = new CheckBox();
((CheckBox)tempControl).Text = txtboxText.Text;
break;
case 3:
tempControl = new RadioButton();
((RadioButton)tempControl).Text = txtboxText.Text;
((RadioButton)tempControl).GroupName = txtboxGroupName.Text;
break;
}
string controlId = "control_id_" + this.NumberOfControls.ToString();
tempControl.ID = controlId;
panel.Controls.Add(tempControl);
this.NumberOfControls++;
ControlTypes.Add(controlId, tempControl.GetType());
}
as you can see, I preserve the id's of the controls, but the viewstate won't update their values.the controls will be added to the form with the desired id, but its values won't be set at all
what should I do?
I am appending rows using item template
<tr>
<td>
<asp:HyperLink ID="HyperLink1" NavigateUrl="bla" CssClass="display:inherit !important;" Text='<%# someFunction(School.Name,"Name") %>' runat="server" />
</td>
</tr>
the problem with the above one is if someFunction(School.Name,"Name") returns null it appends empty tr, so i want to append tr only if someFunction(School.Name,"Name")!=null
So i tried the below code by adding a if condition but it is not compiling !!
It says school.name is not defined
<% if(someFunction(School.Name,"Name")!=null){
<tr>
<td>
<asp:HyperLink ID="HyperLink1" NavigateUrl="bla" CssClass="display:inherit !important;" Text='<%# someFunction(School.Name,"Name") %>' runat="server" />
</td>
</tr>
} %>
You could take care of it from the code behind.
<td id="tdAppend" runat="server"> Content </td>
if(School.Name == null)
tdAppend.Visible = false;
UPDATED ANSWER:
currentItemIndex = -1;
listView.ItemDataBound += listView_ItemDataBound;
CheckQueryString();
//Hide or show the table header based on id
HtmlControl thControl = listView.FindControl("thAppend") as HtmlControl;
if (thControl != null)
{
if (obj.ID == 12)
{
thControl.Visible = true;
}
else
{
thControl.Visible = false;
for (int i = 0; i < listView.Items.Count; i++)
{
HtmlControl tdControl = listView.Items[i].FindControl("tdSchoolName") as HtmlControl;
if (tdControl != null)
{
tdControl.Visible = false;
}
}
}
}
For convenience:
void listView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
currentItemIndex++;
ListViewDataItem dataitem = (ListViewDataItem)e.Item;
HtmlTableRow trControl = (HtmlTableRow)e.Item.FindControl("MainTableRow");
if (IsOdd(currentItemIndex))
trControl.BgColor = "DarkGray";
}
}
private bool IsOdd(int value)
{
return value % 2 != 0;
}
It's a pretty straight forward practice.. Handling the ListView.OnItemDataBinding event.

personally, I don't usually use tables.. it's a fairly odd-looking layout template.
I'm not an asp.net guru, so I'm facing bad times with this silly matter.
I have a registration form where a field (VAT NUMBER called 'piva') must be validate only if from a dropdown list the value "IT" has been selected.
This is the front code:
<asp:TextBox ID="pivaTextBox" runat="server" Text='<%# Bind("piva") %>'
MaxLength="50" Width="400px" />
<asp:RequiredFieldValidator ID="RequiredPiva" runat="server"
ControlToValidate="pivaTextBox"
ErrorMessage="<%$ Resources:Resource, CampoObbligatorio %>" Display="Dynamic"
CssClass="little_text" />
<asp:CustomValidator ID="PivaEsistente" runat="server"
ErrorMessage="Partita IVA esistente nel database" meta:resourcekey="PivaEsistente"
ControlToValidate="pivaTextBox" CssClass="little_text" Display="Dynamic"
onservervalidate="PIVAEsistente_ServerValidate"></asp:CustomValidator>
<asp:RegularExpressionValidator ID="PivaSize" runat="server" ControlToValidate="pivaTextBox" CssClass="little_text" Display="Dynamic" ErrorMessage="Check the VAT Number length. 11 characters and only numbers." ValidationExpression="[0-9]{11}" ValidationGroup="pivaItalia">
</asp:RegularExpressionValidator>
In the code behind I wrote this:
protected void PIVAEsistente_ServerValidate(object source, ServerValidateEventArgs args)
{
string piva = args.Value;
using (CMALinqModelDataContext ent = new CMALinqModelDataContext())
{
var n = (from u in ent.VUser
where u.piva == piva
select u).Count<VUser>();
args.IsValid = n.ToString().Equals("0");
}
}
protected void nazioneDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddl = (DropDownList)sender;
DropDownList ddlProv = (DropDownList)FormUser.FindControl("provinciaDropDownList");
if ("it".Equals(ddl.SelectedValue))
{
ddlProv.Enabled = true;
Page.Validate("pivaItalia");
}
else
{
ddlProv.SelectedIndex = 0;
ddlProv.Enabled = false;
}
}
the first method checks if a VAT number already exists and it works.
The second one check if "it" has been selected from the nations dropdown list and unlock the provinces dropdownlist AND SHOULD validate the VAT number according the RegularExpressionValidator above.
The fact is that it is always validate, but worst even if I get the error message, the form can be submitted.
That's not good.
Anyone could suggest any solution? What am I missing?
Beside capital letters that you have to sort out, if it is the case, the problem is the "SelectedValue" you shall use "SelectetItem".
if (ddl.SelectedItem.Equals("it"))
{
ddlProv.Enabled = true;
Page.Validate("pivaItalia");
}
else
{
ddlProv.SelectedIndex = 0;
ddlProv.Enabled = false;
}
I tested with this on a comboBox(ddl) where I have: it, pippo, papa, etc.., and it works:
private void button1_Click(object sender, EventArgs e)
{
if (ddl.SelectedItem.Equals("it"))
{
label1.Text = "ok";
}
else
{
label1.Text = "no";
}
}
So if you still have problems, please explain better what is happening, may be the problem is now somewhere else.
Looks like your problem is casing.
In your question you state " I have a registration form where a field (VAT NUMBER called 'piva') must be validate only if from a dropdown list the value "IT" has been selected.", yet in your code you are comparing the lowercase value to the selected value in this code:
if ("it".Equals(ddl.SelectedValue))
{
ddlProv.Enabled = true;
Page.Validate("pivaItalia");
}
else
{
ddlProv.SelectedIndex = 0;
ddlProv.Enabled = false;
}
Instead force the values being compared to the same case (either .ToLower() or .ToUpper()), like this:
if ("it".Equals(ddl.SelectedValue.ToLower()))
{
ddlProv.Enabled = true;
Page.Validate("pivaItalia");
}
else
{
ddlProv.SelectedIndex = 0;
ddlProv.Enabled = false;
}
OR
if ("IT".Equals(ddl.SelectedValue.ToUpper()))
{
ddlProv.Enabled = true;
Page.Validate("pivaItalia");
}
else
{
ddlProv.SelectedIndex = 0;
ddlProv.Enabled = false;
}
I have a problem with my dynamic updatepanel that I've created.
The problem is that i want to add a validator,i.e RequriedFieldValidator, to every element that i'm creating on the serverside.
This above works fine.
But when i'm clicking the submit button it does nothing. I can see in the htmlShellcode that a span element is there showing the error, but it has the "style="visibility=hidden".
How do i solve this issue? i'm not really sure i'm doing it right from the beginning either(very new to programming).

But when i'm clicking the submit button it does nothing.
Since I don't see a Submit button, I'm taking a guess that you mean the Add and Remove buttons. If this is the case, the problem is that all your RequiredFieldValidators have the ValidationGroup property set to QuestionGroup but this is not set in any of your buttons.
Modify the Buttons like this:
<asp:ImageButton ID="btnAdd" runat="server" ValidationGroup="QuestionGroup" ... />
