I am using a reapter control and there is one label within the Header Template of the Reapter.But
I want to change the text of the label at run time on the click of my radio button.
But label within the reapter is not directly accessible ..
How to get the label frmo repater control.
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
<asp:Button ID="Button2" runat="server" Text="Button" />
</ItemTemplate>
</asp:Repeater>
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.

I 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

I have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?

View 1 RepliesI have one dropdownlist,one textbox control and one button control.

I need that value in literal controls which is in repeater control.
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?

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
I 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.

I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>

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.
