Forms Data Controls :: DataList ItemCommand Not Firing When Checkbox Changes?
Aug 15, 2010
I have a checkbox inside the item template of a datalist, dtlLate. I want to detect the checkbox change and execute a stored procedure. When I click the checkbox a postback does occur but the dtl Late itemcommand doesn't fire. I am not rebinding the datalist on postback. I have tried with viewstate enabled and disabled. I have used Bold text for the dtlLate in the content page and in the codebehind to make it easy to find.

I'm building a navigationmenu and for that I create repeatercontrol dynamicly from codebehind. This works fine with the exception that the ItemCommand event is not firing. The ItemDataBound-event I bind to the repeater-control is working fine. Can somehow tell me what I'm doing from.
Code ASPX
<div id="subnavigation">
<asp:PlaceHolder ID="phControl" runat="server"></asp:PlaceHolder>
</div>

I have a datalist in my page that has a LinkButton at the beginning of each row that, when clicked, fires the Itemcommand ("select"). There is no issue with this as it works as it should:
[Code]....
But I also thought it would be good if the user could simply click anywhere in the datalist to expand the item and show based on the SelectedItemTemplate. So, I thought, the cleanest would be to add a function in the code behind that adds a click event to the Panel "panItem" that clicks the above mentioned LinkButton like this (fires in Page_PreRender):
[Code]....
Here is where the problem comes in. This works great in IE but not FF3.6 (havent tested it with older version of FF). In FF, I get a JS error saying "dlMapDB_ctl00_btnItemFigNumber is not defined" for the first row, "...ctl01..." for the second row, etc. So the IDs are correct based on the markup (which makes sense since it works in IE).

Here is my code through which i can generate dynamically 2 checkbox group
DataTable dt = new DataTable();
DataList1.DataSource = dt;
DataList1.DataBind();
DataList2.DataSource = dt;
DataList2.DataBind();
Design Page
[code]....
There is two checkbox group which have same datasource, so in both case same checkbox are showing and also same event is firing for both. Here is the event code
protected void CheckBox_CheckedChanged(object sender, EventArgs e)
{
string OpService = ((CheckBox)sender).Text;
}
Now what i want to do is, while check one checkbox from the 1st checkbox group the same checkbox should be selected from the second checkbox group automatically, also if i deselect one checkbox that should be deselect from both checkbox group.

I have a datalist inside of an updatePanel. Within the datalist, for each item I have a linkbutton that when clicked I would like to fire the OnDeleteCommand of the datalist so that I can delete the record.
Problem is that I can never get the event to fire, it simply does a postback and then does not fire the event specified inthe "OnDeleteCommand" argument of the datalist control.
I've read many postings with similar entries, but nothing has worked.

I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"

I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.

It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation

I have <asp:Button ID="btnDelete" ..../> and <asp:DataList ID="lstOrder"..../>
"lstOrder" has <asp:CheckBox ..../> for each "lstOrder" item. I am binding "lstOrder" to DataTable at run time (DataTable is being created dynamically"
"btnDelete" first loops through the "lstOrder" and stores the indexes of items which are marked(checked). Next rows are deleted from the DataTable and "lstOrder" is binded again.
I don't want to postback if none of the items are marked in the "lstOrder"
How to validate ?

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
