Can anyone help me to get the ClientID of a control which is kept in the ItemTemplate of an DataControl? My control is like this.

<asp:ListView ID="ListView1" runat="server">
            <LayoutTemplate>
                 <table ID="itemPlaceholderContainer" runat="server" border="0" style="">
                    <tr runat="server">
                        <td>Contacts</td>
                    </tr>
                    <tr id="itemPlaceholder" runat="server" >

                    </tr>
                </table>
            </LayoutTemplate>
            <ItemTemplate>
                 <tr style="">
                    <td>
                        <asp:CheckBox ID="chkFlag" runat="server" AutoPostBack="true" />
                    </td>                
                    <td><asp:Label ID="LabelContacts" runat="server" Text='<%#Eval("cont_name") %>'></asp:Label>
                    &l开发者_JAVA百科t;asp:HiddenField ID="hfGSM" runat="server" Value='<%#Eval("cont_gsm") %>' />
                    </td>
                </tr>
            </ItemTemplate>
            </asp:ListView>

I need to get the ClientID of CheckBox from inside this ListView. Do anyone knows how to do it? Please help me in this


something like this should work, if you assign it to an attribute of the CheckBox for example, or test it rendering it in the label of the CheckBox:

<asp:CheckBox ID="chkFlag" runat="server" AutoPostBack="true"
  onClick="alert('<%# ((Control)Container).FindControl("chkFlag").ClientID %>')" />

P.S. I just copied from here, search in SO when opening new questions, or do we want to explode their SQL? :D

How do I find the Client ID of control within an ASP.NET GridView?


in the ItemDataBound event handler... you can find the control and get the client id like this

((CheckBox)e.Item.FindControl("chkFlag")).ClientID
0
