I think I am not a beginner in, but now maybe I dont see the solution because it must be so easy..I have a simple Repeater on an UserControl(ascx).After a Postback on a button click I would like loop trough allthe Items from the Repeater, but the RepeaterItem-Collection is Empty!!!!!But NOW it comes, when I move the whole code from the UserControlto the Codebehind of an Page, and move the Repeater also to the Page.It works!!!! The Items-Collection are not empty after the Postback!!!Here is the simple Codebehind from the UserControl:

protected override void OnLoad(EventArgs e)

Forms Data Controls :: Using Usercontrol In EditTemplate In Formview

Jul 24, 2010

In almost all cases, my edit template and insert template in the formview are the same.

So instead of copying pasting the same markup, i decided to put it in a user control. The display works fine, however, the databinding doesn't work anymore. It works fine if I put the markup directly in to the formview template.

Forms Data Controls :: Not Seeing SelectedValue For ListBox In UserControl?

Apr 25, 2010

Using VB.Net/Asp.Net 2008, web app with Master page.I have a content page where all of the content is wrapped in an UpdatePanel that uses a UserControl called GetEmployee.ascx that I created.

In the user control I have a listbox filled with employeeIDs for the DataValueField, in fact for testing to make sure I'm getting the ID I temporarily set the DataTextField to employeeID also. Anyways I keep getting "" error saying I have not selected anything even when I do so I put a breakpoint and set a watch to find out selectedIndex, value and item and nothing.

after the user selects an employee they should click on the "select employee" button so I have some code there to find out which employee was selected. I have events setup in the GetEmployee.ascx user control to get the value selected:


and I have a breakpoint and it hits the "selectedIndexChanged" event first so I put a watch there and see the following.

SelectedIndex = -1
SelectedItem = Nothing
SelectedValue = ""

why am I not seeing the selected value?

Forms Data Controls :: Load The Same UserControl Multiple Times?

Jan 27, 2011

I have a simple UserControl that I've created that simply allows a user to enter the date. For the time being, it has a single Textbox with ID="tbDate". I am trying to dynamically add this control multiple times via (for example) `placeholder.Controls.Add(LoadControl())` but am receiving the error "An entry with the same key already exists". I could, perhaps, change the ID of the elements but then it would be difficult to grab the value entered by the user.

Forms Data Controls :: Use UserControl Inside An EditTemplate Of A ListVIew?

Oct 5, 2010

I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.

A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing

A UserControl in EditTemplate.

Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)

Forms Data Controls :: UserControl In Page / Hiddenfield In Each Is Not Empty?

Nov 2, 2010

I have a repeater which always has 1 UserControl, however the UserControl can vary, lets say it could be UC1, UC2 or UC3.

When I come to validate that a hiddenfield in each is not empty, I iterate through the repeater items but I have to do a findcontrol on UC1 check an exposed value, then do the same for UC2 then UC3. In all its a bit unwieldly.

What it would be great to do is iterate through the repeater items find the hiddenfield (which is the same name for each UC) and test that in one go, like below:

foreach(RepeaterItem item in Repeater1)

... some code here to start off with

HiddenField hfAnswer = (HiddenField)item.FindControl("HF_Answer");
if(hfAnswer != string.Empty)
do something here

Forms Data Controls :: Datagrid Paging Inside Usercontrol?

Apr 4, 2010

I have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.

Forms Data Controls :: Same Instance Of Usercontrol In Two Places In Same Page?

Mar 23, 2011

i am using a usercontrol with repeater for custom paging in grdiview. Everything works fine. I am able to display link buttons and able to pull exact records. Now i have a little user friendly requirement. The pager usercontrol should appear at top of grid and bottom of grid. For that i have placed two instances of usercontrol. I am supposed to place same instance of usercontrol in two places so that whatever button click in any instance should happen in all available instances. The issue is i clicked page 2 (link button) in top pager user control. Its changed to selected mode(non clickable) where as bottom remains same, page 2 is clickable. How can i proceed?

User Controls :: How To Find GridView Inside UserControl Using JQuery

Apr 13, 2013

Click Me in a UserControl. I downloaded the sample attached there and its working fine but i am trying to create UserControl out of it. No rows are getting loaded on scrolling down. I modified the code to look like this..

var lastProductId = $("#<%=Test1.GridView1.ClientID %> tr:last").children("td:first").html();
//get last table row in order to append the new products
var lastRow = $("#<%=Test1.GridView1.ClientID %> tr:last");

function GetRowsCount() {
//Count no. of rows except header row in the grid.
var rowCount = $('#<%=Test1.GridView1.ClientID %> tr').length - 1;
return rowCount;

Its giving me error: The name 'Test1' does not exist in the current context. Test1 is the Id of my USerControl. Test1 is the ID of UserControl. I found your tutorial on similar issue but i did not use it because i am not using stored procedure and i know nothing about XML. At this point i just want to make the sample attached in that article(one i provided) to work as a UserControl.
