Hi, 

Does anyone have an example of using a colorpicker in a grid with batch edit? Ideally in vb but C# is OK too.

thanks

Hi Helen,

Please try the below code snippet which shows batch editing with color picker.

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" DataSourceID="SqlDataSource2"
    GridLines="None" AllowPaging="true">
    <MasterTableView EditMode="Batch" CommandItemDisplay="Top">
        <BatchEditingSettings EditType="Cell" />
        <Columns>
            <telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" HeaderText="OrderID" />
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" />
            <telerik:GridTemplateColumn HeaderText="ColorPicker">
                <ItemTemplate>
                    <asp:Label ID="ColorLabel" runat="server" Text='Color Picker'></asp:Label>
                </ItemTemplate>
                <EditItemTemplate>
                    <telerik:RadColorPicker ID="RadColorPicker1" runat="server" ShowIcon="true">
                    </telerik:RadColorPicker>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Thanks,
Shinu

Thanks, 

I have tried this and can't get it to work - I get no red triangle and the e.Commands.Count remains at 0 in my BatchEditCommand sub so nothing gets updated.

Hi Helen,

In scenarios like the described things should be handled manually. In order to make things work you will need to subscribe to the OnBatchEditGetCellValue,OnBatchEditSetCellValue,OnBatchEditGetEditorValue and OnBatchEditSetEditorValue event like explained here. Additionally I have prepared a small website which demonstrate a possible realization of the scenario. The example provided should help you resolve the problem.

Getting closer....

I'm having trouble with the insert. Both the  OnBatchEditGetCellValue and OnBatchEditSetCellValue return null from $telerik.findElement(container, "ColorLabel").

These lines are fine for updates - just not working for inserts. 
I am working with master pages.

Thanks

Hi Helen,

Indeed the example previously provided will not work for insert items. In order to resolve the matter the JavaScript logic should be modified. In general the edit and insert items can be distinguished by their ids. The insert items contain a "-" in their id. By using this indicator one can execute different logic to achieve the result which he is after. Please find the modified website which now works as expected.
