The goal is a facebook style interface where one users post can be commented on by another by clicking on a "comment" link. I am finding this some what difficult.
First - although I think that I will have to use a nested repeater, the initial issue is how to ID a text box that is embedded in the repeater.
<asp:Repeater ID="rptmain" runat="server">
I have a repeater control bound to a dataset. Within that repeater I have several further controls one of which is a dropdownlist. I trap the OnSelectedIndexChanged event of that dropdownlist because I want to recalculate some figures presented on the same row within the repeater.
How do I reference other controls which are on the same row of the repeater as the dropdownlist ? Is there an index property or other mechanism whereby I can identify the "current" row?
I have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.
My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:
"Object reference not set to an instance of an object"
I'm just starting out in ASP coding and would like to know what I'm not doing right?

I have a javascript in a .js file to pad zeros to the left of a number in a textbox. I have a textbox on a search screen for which this function works just fine. But when I tried to apply the same function to a textbox in a repeater on the data entry screen, it just does nothing. I get no errors, but it doesn't pad the field when I leave it.avascript function:
function pad(tb, length) {
var str =
'' + tb.value;

I have a nested repeater which displays a food menu - e.g.
Sub Heading
- Food 1
- Food 2
- Button 1
Another Heading
- Food 1
- Food 2
- Button 2
etc. etc.
What I have is a series of buttons inside the itemtemplate of the parent repeater (button 1 and button 2) which, when clicked, i need to somehow add a new blank textbox to below food 2 in whichever section it is clicked
I am having trouble doing this. See my code snippet below:
[Code]....
When I run this though, I receive an error of "object reference not set to an instance of object..."
Do I need to actually find a control within the footertemplate itself?

I display a GridView where ther user can choose a Datarow with the select action. I catch the selection with the "SelectedIndexChanged" event of the GridView.
[Code]....
My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").

View 7 RepliesI have a repeater control that is getting exported to excel. Well excel will no longer show the data that was in the textboxes. I've read the article on exporting a gridview having the same problem and how you replace the texboxes with literal contrls. I was wondering if there is an article like it only for a repeater control.

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?

Here is what I have:

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.
