datagrid template and selected index

[Darren Wooding]

Hi,

can anyone shed any light on this? I have item templates
defined to add controls to a datagrid - all this is fine,
apart from I can not set the selectedindex on a
dropdownlist when it is added using a template. If I add
the DDL dynamically on the form (before or after I add the
grid with the template), then the selected index is fine.

Bascially the code is (in page init):

1. Add a grid to the page.
2. Use templates to add controls (including the DDL)
3. Set the DDL selected value in the template.
4. grid.databind

Any thoughts?

Many thanks for your time with this.

Darren

hi Darren,

I'm not sure if this method on the article will work for you, as you have
stated that you are adding the control to the template dynamically, if so
maybe you could try retrieving you DropDownList control in the ItemDataBound
method, then retrieving it from the cell, casting it to a dropdownlist and
setting the selectedIndex ?
Not sure if this will work for you but maybe you could give it a try

Glad you solved

Thanks Alessandro,

I have just managed to set the selected item by capturing
the prerender event using an AddHandler in the template.
Its not perfect (as I need to check for postback) but it
seems to do the trick.

Thanks for taking the time to help.
