How to prevent ajax toolkit DropDownExtender from closing on click?
- by Abe Miessler
I have the code below to implement a dropdownlist with checkboxes. My problem is that every time i click a checkbox the dropdownlist closes and i need to reopen it to select more checkboxes. How do i make it so the dropdownlist dosn't close until i click off of it?
<asp:Panel ID="pnl_Items" runat="server" BorderColor="Aqua" BorderWidth="1">
<asp:CheckBoxList ID="cbl_Items" runat="server">
<asp:ListItem Text="Item 1" />
<asp:ListItem Text="Item 2" />
<asp:ListItem Text="Item 3" />
</asp:CheckBoxList>
</asp:Panel>
<br />
<asp:TextBox ID="tb_Items" runat="server"></asp:TextBox>
<ajax:DropDownExtender ID="TextBox1_DropDownExtender"
runat="server"
DynamicServicePath=""
Enabled="True"
DropDownControlID="pnl_Items" on
TargetControlID="tb_Items">
</ajax:DropDownExtender>
