Basically I've got a many-to-many table mapping products to special occasions. I'm trying to have an outter grid with the products and an inner-grid where the users can add or delete the special occasion relationships. The code works if I remove the parenttablerelation and where clauses from linqdatasource2, but throws that weird bool error when I try to add them back in. There are no bool values in the linqdatasource2 table so not sure where that value is coming from.

Does anyone see something in my code that could be causing issues? Or is this scenario just not possible with radgrid and linq?

Problem with GridTemplateColumn when calling ExportToExcel

Hi,

I have a RadGrid with a template column that doesn't appear properly in Excel after calling ExportToExcel. Currently the column appears, but the only value I see in the fields are the values from the DataField that the column is bound to. I am wanting to see my custom data that gets populated on the databind for this field in each row and does get shown correctly in the browser. This for some reason does not show in the exported excel document.
I also find I can only view anything in Excel after setting the Format to GridExcelExportFormat.ExcelML. If I don't set it to this then I get an excel document with no data in it. Setting MasterTableView.EnableColumnsViewState = true rectifies this, but only if I remove my template column, else I get the "Cannot create column with the specified type name: GridTextBoxColumn" error. So obviously that doesn't help me.

Any help would be greatly appreciated.

Thanks,
-Lindsay

Handling postback on PanelBar with custom controls

I have a PanelBar that is partially populated (via code behind) with a custom User Control. When the user clicks on the control, how should I handle the postback and rebind the data (with controls)? Currently the custom controls are being dropped when the item click event is fired.

accessing ItemCommand and ItemDataBound events of radGrid

I have a radGrid within a radPanelBar. The grid is loading properly. How can I get access to the grid when a user clicks an ImageButton within a grid row? I would typically do this via the ItemCommand event.

I'd also like to run some code during the ItemDataBound event of the grid (to set the CommandArgument). How can I accomplish this?

Thanks.

FrozenColumn and Navigation in excel-like grid

Hi,

I have a radgrid who need to have the firstcolumn frozen. I set the property allowscroll (true), frozencolumncount (1) and usestaticheader(true).

If i use the scroll manually it works fine.

Also, on key press event of the grid i change my focused cell. But when i'm navigating to the right my first column(the frozen one) desapear like the frozen column isn't working correctly. The first column will be hidding a bit more each time i'll navigate to the right till it deseapear completly.

If i try to navigate back to the left or use the scroll i won't be able to make it reapear completly.

How can i keep the column frozen while i'm using navigation in my grid??

Thx again for your time!!!

[Solved] select a tabstrip's tab

Hi,
I hope someboby could give me a hint here. I have a tabstrip on a masterpage:
        <telerik:RadTabStrip ID="rtab1" runat="server" AutoPostBack="True">
          <Tabs>
            <telerik:RadTab runat="server" Value="radtab1" Text="1" runat="server"
                NavigateUrl="~/page1.aspx" SelectedIndex="0" Selected="True" />
            <telerik:RadTab runat="server" Value="radtab2" Text="2" runat="server"
                NavigateUrl="~/page2.aspx" SelectedIndex="1" />
          </Tabs>
        </telerik:RadTabStrip>
Click to a tab, the page is displayed fine except the selected tab does not show as it is selected (like having new background color).
How to make it look like being selected. I tried the SelectedCssClass but it doesn't work.
Thanks.

RadPanelBar postbacks

I can't seem to get postbacks working.

I've tried both BeginForm and BeginFormRoute methods around the RadPanelBar.

    
            <% using (Html.BeginRouteForm("AddFilter", FormMethod.Post)) { %> 
        
                    <telerik:RadPanelBar ID="filterAttributes" runat="server" Width="200px" /> 
        
            <% } %>

I've also tried the postbackurl attribute but to no avail. Is there an example anywhere of the RanPanelBarItem posting back to a controller action?

Cheers
Mac.
