Dynamically generated control id is different at runtime

[mazdotnet]

Hi all,

I have Repeater dynamically adding textboxes to a placeholder and
connecting it to AjaxControlTool kit.PopupContro lExtender which works
fine. I'm adding the textboxes using the following

TextBox tbxQty = new TextBox();
tbxQty.ID = "tbxQty" + id;
phUserInput.Con trols.Add(tbxQt y);

Now in the OnCommand I want to read the value of the textbox by using
((TextBox)FindC ontrol("tbxQty" + id)).Text which fails because my
textbox automatically because

<input type="text" id="rptAvailabl eProducts_ctl01 _tbxQty0" />
instead of
<input type="text" id="tbxQty0" />

How can I force it to use tbxQty0 for the generated id at runtime
instead of rptAvailablePro ducts_ctl01_tbx Qty0? Or in the OnCommand
event is there any way to extract the value of tbxQty0 from
rptAvailablePro ducts_ctl01_tbx Qty0?

Thanks
Maz

Re: Dynamically generated control id is different at runtime

FindControl() only searches the current naming container. to use
findcontrol, you need to call it on the datarepeater template that hosts
the control. i assume you made a unique id, so you can just do a
recursive search for a control with the id.


var list = ControlWalker(t his, ctl =ctl.ID == "tbxQty" + id");


public List<ControlCon trolWalker(
Control ctl,
Predicate<Contr olmatcher)
{
var list = new List<Control>() ;
if (matcher(ctl)) list.Add(ctl);
for (int i=0; i < ctl.Controls.Co unt; ++i)
{
var childList = ControlWalker(
ctl.Controls[i],matcher);
if (childList.Coun t 0)
list.AddRange(c hildList);
}
return (list);
}
