How to get label id in div tag for each row in repeater control?
View 1 Repliesaspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.

how to get the ID of a label inside a Repeater for jquery purposes? I've tried clientID, but doesn't work because it's inside the repeater ofc
View 1 RepliesI have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself. I'm not sure what I'm doing wrong here. OnItemDataBound is firing because "hello1" is being written but if I put anything inside of the For Next loop of rptMarketFundamentals, nothing is run inside of it.
<asp:Repeater id="rptMarketFundmentals" runat="server" DataSourceID="dsMarketFundamentals" OnItemDataBound="rptMarketFundamentals_ItemDataBound">
<asp:Label ID="lblOwnershipCategory" runat="server" Text='<%# Eval("OwnershipCategory") %>' />
</asp:Repeater>
Sub rptMarketFundamentals_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs)
Response.Write("hello1") 'this works
Dim dataItem As RepeaterItem
For Each dataItem In rptMarketFundmentals.Items
Response.Write("hello2") 'this does not work
Dim lblOwnershipCategory As Label = CType(dataItem.FindControl("lblOwnershipCategory"), Label)
If lblOwnershipCategory.Text.ToLower = "family firm" Then blOwnershipCategory.CssClass = "highlight"
End If
Next
End Sub
I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.

View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

View 2 RepliesI am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

Imagine the output of the above repeater containing 100 rows. (1 label, and 1 button on each row).
Goal: when I click the button, I want the appropriate label to be updated. I dont know how to do this.
I can reference a label via:
Label myLabel2Update = (Label)Repeater1.Controls[0].Controls[0].FindControl("Label1");
But ofcourse, it will be the same label each time (not necessarily the label that needs to be updated). I need to update the label that is on the same row as the button.
I have something like this:

This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.
I tried this technique as suggested on another forum and a couple of other things, suggested on SitePoint as well as others but to no avail. Im trying to find the Label in the repeater to display information depending on the output. However I was presented with the following error:
"Index was out of range. Must be non-negative and less than the size of the collection.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"
It highlights the problematic script as:
Label lblStatus = rptGeneralEnq.Items[0].FindControl("lblStatus") as Label;
I'm trying to access the Label, in the repeater, so that depending on if the text origionally displays true or false (as the label grabs the 'bit' datatype for that record to display) to then change the text to something more appropriate (completed/outstanding) - if at all possible.

How to get the label frmo repater control.
<asp:Repeater ID="Repeater2" runat="server">

<asp:Button ID="Button2" runat="server" Text="Button" />

Lets say I have the above situation, and I need to update the appropriate label based upon which button is clicked. I have no idea how to do this. I can find a label via: (Label)Repeater2.Controls[0].Controls[0].FindControl("Label1");
But that only gives me the same label each time (so no matter which button I click the same lablel gets updated). How would I find the correct label to update?
how can i set the max-width of the label field, and use multiple line if the text length larger than max-width in the templateitem of repeater. i set the width to 10, but can't fix the length.
View 4 RepliesI have a repeater set up which takes all records from a SQL DB table and displays. One of the items in this repeater is a Label. The Label's job is to display the 'Responded' field of the database, which is a 'bit' Datatype.
However, when the label displays naturally, it will show TRUE or FALSE. As this is not appropriate for the end-user they would prefer If True = Completed and if False = Outstanding.
I have written the script to do this in an ItemDataBound field, so that (hope my understanding of itemdatabound is correct), everytime a record is found it checks to see what the value is in responded field and 'if true then do X else do Y'.
However, when I have ran it through debug mode it shows that the Label Text of the label is just "". Therefore it will always show 'Outstanding'. In addition, the AssociatedControlID is also blank (""), although I am unsure whether this would present a problem or not.
