I everyone,

I need to force a event fire when i set a new selectedvalue. So, i've got this code:

Protected

Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged

DropDownList2.SelectedValue =

CInt(dr("cod_loja").ToString.Trim)

End

Sub

Protected Sub DropDownList2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList2.SelectedIndexChanged

Response.Write(

"DONE")

End

Sub

This is a sample code. The idea is to fire the SelectedIndexChanged event when SelectedValue is updated.

I'm not sure if you can force the event to fire, but you can call the method directly.

DropDownList2_SelectedIndexChanged(Nothing, Nothing)

You can also add a check to make sure the value actually did change before you call the method.

I've found a way with "Call DropDownList_SelectedIndexChanged(DropDownList2,e)"

Yes, before make the call, i check if the selectedvalue is different... if not, it don't call anything.

Thanks.
