find control in repeater

Hello All,

I have a page with the wizard control. In one of the steps I have repeater1 and each field has a textbox called questionExpained. I need to loop through the repeater and add the textbox text to the database. I'm having issues finding the textbox. Here is the code.

<asp:Wizard ID="Wizard1" runat="server" ActiveStepIndex="0" DisplaySideBar="False">
<WizardSteps>
            <asp:WizardStep ID="WizardStep1" runat="server" title="Step 1">
<asp:Repeater ID="page1Repeater" runat="server" >
        <ItemTemplate>
                 <asp:TextBox ID="questionExplained" runat="server" Height="72px" TextMode="MultiLine" Width="453px"></asp:TextBox>

</ItemTemplate>
        </asp:Repeater>
</asp:WizardStep>
            <asp:WizardStep ID="WizardStep2" runat="server" title="Step 2">
and so on....



VB CODE

 For Each item As RepeaterItem In page1Repeater.Items
            Dim b As TextBox = TryCast(item.FindControl("question1Explained"), TextBox)
            Response.Write(b.Text + "<br>")
        Next

' This loops but does not return any values.

Open in new window

did you set breakpoint and see what value are you getting for "page1Repeater.Items"?
Make sure your repeater has data items to display.

Hi guru_sami,

I do not know how to properly user the debugger. I can set the breakpoints but I do not know how to interpret the results of the debugger.

guru_sami

Say you set the breakpoint on statement like below:

For Each item As RepeaterItem In page1Repeater.Items
Dim b As TextBox = TryCast(item.FindControl("question1Explained"), TextBox)
breakpoin here---> Response.Write(b.Text + "<br>")
Next

Then upon debugging:
1: does your execution stop at breakpoint statement?
2: If it does, it means you have items for repeater to display and if Not then something going on
3: Once it stops at bp statement, you can mouse-over the Items and dig into its Count property to see how many items.

guru_sami,

Ok, in the debugging the repeater is showing an item count of 8 which is the number of results bound to the repeater.

guru_sami

hmmm so when you say trouble over finding textbox...do you mean b is null or ..?

So how about the Text when you hover over b.Text while debugging...what is the value for that?

The value for b.text is showing as ""

guru_sami

hmmm... repeater has items but tb is not retaining value...not sure exactly what's happening....
when exactly your code block executed and how's your repeater databound?
Do you have code snippet which I can use to replicate the issue?
