Dear all,
I want to add the function to gridview
1.) when edit mode, the textbox can validate before edit, e.g. if the fields
is required field, user need to fill in something before edited

2.)some field are bound with drop-down list value(get from db), when it is
edited, it can be drop-down list

3.) when user clicks delete, popup a javascript box to comfirm, before delete

> 1.) when edit mode, the textbox can validate before edit, e.g. if the

use TemplateField with a TextBox and a RequiredFieldValidator linked to it.

> 2.)some field are bound with drop-down list value(get from db), when it is

again, use TemplateField with a DropDownList which has DataSource and
SelectedValue properties set accoding to the item beeing edited.

inject a client-side script into the button's "onclick" attribute to prevent
posting back.

if ( !window.confirm( "Are you sure that you want to delete selected
item?" ) ) return false;
