}
解决方案
I have a dropdown list that populates on first run with code.
The autopostback is true, but the selectedindexchanged event is not firing.
Can someone please help me?
What I have tried:
<pre><asp:DropDownList ID="dproy" runat="server" Width="180px" AutoPostBack="True" AppendDataBoundItems="true" OnSelectedIndexChanged="dproy_SelectedIndexChanged1" CausesValidation="True" OnTextChanged="dproy_TextChanged" ViewStateMode="Enabled"> </asp:DropDownList>
protected void dproy_SelectedIndexChanged1(object sender, EventArgs e)
{
idproy = dproy.SelectedIndex.ToString();
lbl1.Text = idproy;
}
