Combobox in a DataItemTemplate

Question

Hi,

In the AspxGridView there are two comboboxes in DataItemTemplate, manually loaded. So when user selects one field of the first combo second will be disabled, i wrote this:

<dxe:ASPxComboBox ID="cmbEqualNotEqual" runat="server" 
                                                ClientInstanceName="cmbCEqualNotEqual" EnableClientSideAPI="true">
                                                <Items>
                                                    <dxe:ListEditItem Text=" " Value="0" />
                                                    <dxe:ListEditItem Text="Eşittir" Value="1" />
                                                    <dxe:ListEditItem Text="Eşit Değildir" Value="0" />
                                                </Items>
                                                <ClientSideEvents SelectedIndexChanged="function(s,e){
                                                    alert(s.GetEnabled());
                                                    var selectedIndex = s.GetSelectedIndex();
                                                    if(selectedIndex == 2)
                                                    {
                                                        cmbCBiggerSmaller.SetEnabled(false);
                                                    }
                                                }" />
                                            </dxe:ASPxComboBox> 

But this code disables the combo at the last row, not the row user works on. How can i disable the row user works on?

Thanks

Hi,

The problem appears because the ClientInstanceName property is set for all editors in the same column to the same value. A possible solution is to handle the HtmlRowCreated event of the ASPxGridView and set the ClientInstanceName for both editors to a unique value. Also, in this event handler you should write the client side SelectedIndexChanged event handler. Finally, to obtain an editor instance, use the ASPxGridView's FindRowCellTemplateControl method.
