Question

hi I have this gridview like this.

<asp:DropDownList ID="triggerDropDown" runat="server" AutoPostBack="true" onselectedindexchanged="triggerDropDown_SelectedIndexChanged">

<asp:GridView ID="myGridView" run="server">
     <Columns>
          <asp:TemplateField HeaderText="Column 1">
               <ItemTemplate>
                   <asp:DropDownList ID="myDropDown1" runat="server" />
               </ItemTemplate>
          </asp:TemplateField>

          <asp:TemplateField HeaderText="Column 2">
               <ItemTemplate>
                   <asp:DropDownList ID="myDropDown2" runat="server" />
               </ItemTemplate>
          </asp:TemplateField>
     </Columns>
</asp:GridView>

now, when I change my triggerDropDown I want to change also all of the DropDowns inside Column 1 how can I do that?

protected void triggerDropDown_SelectedIndexChanged(object sender, EventArgs e)
{
    // what should I do here?
}

Actually I can use GridViewRow 🙂 I just have to find the GridViewControl and get its Rows attribute which is a GridViewRow and now I can do a foreach of each row.

foreach (GridViewRow gridViewRow in (this.FindControl("myGridView") as GridView).Rows)
{
    // I can see all elements of my row here as if I am traversing on GridViewEvents
}
