Hi,

i have  a listview, in both Insert Template and Update Template i have the same drop downlist, i would like to create event for SelectedIndexChanged for this DropDownList,

i want that these two controls will use the same event function, but i would like to identify which one of the control call the event, how can i do that ?

Thanks.

    protected void CommonSelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList Source = sender as DropDownList;

        if (Source.ID == "DropDownList1")
            Response.Write("DropDownList1");
        else if (Source.ID == "DropDownList2")
            Response.Write("DropDownList2");
        else
            Response.Write("Bad sender");
    }

Thanks, but the both have the same name...

i would like to indentify from who is the source template of the dropdownlist, was it the insert template or the update template.

Thanks 

 You can check the parent of the DropDown  (you may have to cast it)

        DropDownList Source = sender as DropDownList;

        if (Source.Parent == ...

Sorry but i do not understand,

what should i cast ? the parent control ? to which control shold i cast it ?

i just want to know who is the template who fired the event,

Thanks

The previous poster is correct. That is practically the only other option left to you at this point :

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList ddl = (DropDownList)sender;
        ListViewItem lvi = (ListViewItem)ddl.NamingContainer;
        if (lvi.ItemType == ListViewItemType.InsertItem)
        {
            //in insert template
        }
    }
