how to refresh screen after delete a record

[J]

Hi, all
I have a simple question but have no clue how to do this:
I have a datagrid in a web form which presents each user's info, after admin
selected a user, then click 'delete' button, that user will removed from backend
database. Now, how can I have screen refresh to display updated data?

Thanks in advance.

When the button is clicked, and the codebehind event fires, let's call it
"MyGrid_OnItemC ommand", you need to rebind your datagrid..since you didn't
give us your existing code, this will hopefully give you an idea:
sub page_load
if not Page.IsPostBack then
BindUserGrid()
end if
end sub

private sub MyGrid_OnItemCo mmand(s as object, e as DataGridCommand EventArg)
select e.CommandName.T oUpper()
case "DELETE"
UserUtility.Del eteUser(Convert .ToInt32(e.Comm andArgument)) 'delete
the user from the backend database
BindUserGrid(); //rebinds the grid
end select
end sub

private sub BindUserGrid()
MyGrid.DataSour ce = UserUtility.Get AllUsers() //gets the user
MyGrid.DataBind ()
end sub
If GetAllUsers was returning a cached result, you'd need to invalidate the
cache. the best place to do this, in the above code anyways, is in the
UserUtility.Del eteUser function

Or you can use the MS/DAAB, which is much better. It takes care of
