Hi,

I am trying to check some combo items from a Radcombobox inside a GridTemplateColumn but unfortunately I cannot get it to work. Instead when I directly set the checked attribute on a checkbox I obtain the correct functionality. The RadGrid is bound to a datasource which all combo items are defined with boolean values (SyncVariantLocalizations, SyncVariantPictures, etc).

Code working:
<asp:CheckBox ID="CheckBox5" runat="server" Enabled="false" Checked='<%# Eval("SyncVariantLocalizations")%>' />

Code not working:
<telerik:GridTemplateColumn UniqueName="SyncSetting" HeaderText="Sync Settings" HeaderStyle-Width="232">
                                    <ItemTemplate>
                                        <div style="float: right;">
                                            <telerik:RadComboBox ID="RadComboBoxSyncConf" runat="server" Width="220px" CheckBoxes="true" EnableCheckAllItemsCheckBox="false" DropDownAutoWidth="Enabled">
                                                <Items>
                                                    <telerik:RadComboBoxItem Text="Product Localizations" Value="SyncProductLocalizations" Checked='<%# Eval("SyncProductLocalizations")%>' Enabled="false" />
                                                    <telerik:RadComboBoxItem Text="Product Pictures" Value="SyncProductPictures" Checked='<%# Eval("SyncProductPictures")%>' Enabled="false" />
                                                    <telerik:RadComboBoxItem Text="Product Categories" Value="SyncProductCategoryMap" Checked='<%# Eval("SyncProductCategoryMap")%>' />
                                                    <telerik:RadComboBoxItem Text="Product Manufacturers" Value="SyncProductManufacturerMap" Checked='<%# Eval("SyncProductManufacturerMap")%>' />
                                                    <telerik:RadComboBoxItem Text="Variant Localizations" Value="SyncVariantLocalizations" Checked='<%# Eval("SyncVariantLocalizations")%>' />
                                                    <telerik:RadComboBoxItem Text="Variant Pictures" Value="SyncVariantPictures" Checked='<%# Eval("SyncVariantPictures")%>' />
                                                    <telerik:RadComboBoxItem Text="Variant Attributes" Value="SyncVariantCustomAttributes" Checked='<%# Eval("SyncVariantCustomAttributes")%>' />
                                                </Items>
                                            </telerik:RadComboBox>
                                        </div>
                                    </ItemTemplate>
 
                                </telerik:GridTemplateColumn>


Thanks.

Hello,

When you used "Eval" in RadComboBox at that time,Then .net is try/trying to find this item's in RadComboBox's DataSource. not in RadGrid's DataSource.

As per your code, you do not assigned any DataSource in RadComboBox That's why you got this issue.

Correct Code:

<telerik:GridTemplateColumn UniqueName="SyncSetting" HeaderText="Sync Settings" HeaderStyle-Width="232">
                       <ItemTemplate>
                           <div style="float: right;">
                               <telerik:RadComboBox ID="RadComboBoxSyncConf" runat="server" Width="220px" CheckBoxes="true"
                                   EnableCheckAllItemsCheckBox="false" DropDownAutoWidth="Enabled" SelectedValue='<%# Eval("SyncProductLocalizations")%>'>
                                   <Items>
                                       <telerik:RadComboBoxItem Text="Product Localizations" Value="SyncProductLocalizations"
                                           Enabled="false" />
                                   </Items>
                               </telerik:RadComboBox>
                           </div>
                       </ItemTemplate>
                   </telerik:GridTemplateColumn>


In-Correct Code
<telerik:GridTemplateColumn UniqueName="SyncSetting" HeaderText="Sync Settings" HeaderStyle-Width="232">
                       <ItemTemplate>
                           <div style="float: right;">
                               <telerik:RadComboBox ID="RadComboBoxSyncConf" runat="server" Width="220px" CheckBoxes="true"
                                   EnableCheckAllItemsCheckBox="false" DropDownAutoWidth="Enabled" SelectedValue="0">
                                   <Items>
                                       <telerik:RadComboBoxItem Text="Product Localizations" Value="SyncProductLocalizations"
                                           Checked='<%# Eval("SyncProductLocalizations")%>' Enabled="false" />
                                   </Items>
                               </telerik:RadComboBox>
                           </div>
                       </ItemTemplate>
                   </telerik:GridTemplateColumn>


Let me know if any concern.

Thanks,
