Looping through repeater only finds first checked checkbox, not the rest

Hello,

I have a repeater with a list of products in it. Each item in the
repeater has a checkbox, allowing the product to be selected. When a
link button is clicked, I want to loop through the repeater and handle
each product whose checkbox is checked.

The repeater looks (greatly chopped down) like this...

<asp:Repeater ID="rptProducts " RunAt="Server">
<ItemTemplate >
<li><asp:CheckB ox ID="chkDelete" RunAt="server"/>
<%#DataBinder.E val(Container.D ataItem, "PName")%>
</ItemTemplate>
</asp:Repeater>

and the code for the link button looks like...

void lbtDeleteProduc ts_Click(object o, EventArgs e) {
for (int i=0; i<rptProducts.I tems.Count; i++) {
if (((CheckBox)rpt Products.Items[i].FindControl("c hkDelete")).Che cked) {
// do stuff here
}
}
}

The problem is that the loop works fine for the first product checked,
but not for any others. The weird thing is that this code is pretty much
identical to code I have used elsewhere that works fine. I can' see why
this only picks up the first checked checkbox. Anyone any idea why?

TIA

I use the following code and have got it working all the time

foreach(Repeate rItem rptItem in ptProducts.Item s)
{
CheckBox chk = (CheckBox) rptItem.FindCon trol("chk_Selec t");
if(chk.Checked)
// do stuff here;
}

>I use the following code and have got it working all the time

Thanks, but that did the same as my code.

I have this sort of code working in plenty other places, I'm sure
there's some quirk here that I haven't noticed. I was hoping someone
else would spot it ;-(
foreach(Repeat erItem rptItem in ptProducts.Item s)
{
CheckBox chk = (CheckBox) rptItem.FindCon trol("chk_Selec t");
if(chk.Checked)
// do stuff here;
}

Hello - I'm using a Repeater control to render information in a very customized grid-like table. The Repeater control is binded to a DataSet with several records of information. Within the Repeater control, I've placed DropDownLists and CheckBoxes. When the user has updated the information, he/he clicks the submit button which is outside the scope of the Repeater control.

Hello, I have a page in which I'm trying to give the user the chance to manipulate a list of items.

I can pull the values out of the database OK and display them in a repeater. What I want to do is have a set of controls below the...

Hi, I have been trying to get a checkbox added to a repeater control of mine and then try to access events of the repeater control when a user clicks the checkbox. At first, since the control is tied to xsl, I added the checkbox there. That works fine, but I cannot get any information about the checkbox (i.e. checked, unchecked, etc) when I pass data from the xsl over to a method in java. I can get info on the other columns but not...
