how to reload data based on condition

[Guest]

I have a combo and a datagrid in a page.
Combo box values are loaded on page_Load.
Datagrid is populated based on values selected in the combo (I am using
selectedIndexchange event)

I need to make a default value for the combo(first value available) and
populate the datagrid based on this value on page_Load itself.(Applicable to
many pages in my application)
I tried changing the selectedindex = 1. But the change event is not firing.

How can i achieve this without extra coding(As the system is in production)
Thanks in advance.

Setting SelectedIndex will not fire the event. Rather, call the
DropDownList's SelectedIndexChanged event handler method directly on page
load after setting SelectedIndex.

I think u forgot to set the combo box properties "AutoPostback" to "true"

1 more thing is the default index for combo should be start from "0"

Hi suresh,

As a work around for your problem u can explicitly call the selected
indexchanged event handler as soon as you set the selected index to 1

combobox_SelectedIndexChanged(Nothing, Nothing)

Hope this helps
