Hi all

I want to make an editable grid in Row Details Template.. What I did is that from a Linq Query i fill the observable collection and bind the outer grid with it.. The outer grid shows the data in the grid.. Now when I select a row I want to open a new grid based on the selected row.. How will i do that also i want editable fields in this inner grid.. When i code this it throws an exception saying that as the data in the grid is from a linq query and the properties in linq query are readonly so they can not be edited.. I am very confused due to this.. Help me in solving this issue..

P.S> My linq query uses 3 to 4 joins.

 

I created custom column;
It works fine but when I am trying to clear a cell I am geting "Value Cannot be converted" validation error.
My binding is to the nullable double.
Please advise what to do.

thanks

Hi,

How can i route the DropDownOpened event raised by the RadComboBox to a handler in the viewmodel?

Thanks.

I have a RadDocking with two RadSplitContainers in it. In the first Container I have one Pane and in the second Container I have a DocumentHost with n Panes. How do I prevent the Panes from the DocumentHost from docking in the first RadSplitContainer (or force them to only dock in their "own" SplitContainer)?

My structure looks like this:

hi, is it possible to change the borderstyle of a radgridview according to a cell value?

I have enabled Column Resizing (CanUserResizeColumns="True") for my GridView.  When I attempt to resize the columns I see the left and right arrow while hovering over the column edge.  When I click and drag the mouse to resize the column, the column resize a couple of pixels and then the whole column header starts to drag like when you re-order the columns. My GridView is defined as follows:

<telerik:RadGridView x:Name="gridViewAccounts" Grid.Column="1" Grid.Row="2" telerikGridViewFilter:CustomFilterRow.IsEnabled="False" RowDetailsTemplate="{StaticResource AccountRowDetailsTemplate}" ColumnWidth="*" HorizontalAlignment="Stretch" SelectionMode="Extended" telerikDragDrop:RadDragAndDropManager.AllowDrag="True" telerikDragDrop:RadDragAndDropManager.AllowDrop="True" Loaded="gridViewAccounts_Loaded" AutoGenerateColumns="False" CanUserFreezeColumns="False" SelectionUnit="FullRow" AddingNewDataItem="gridViewAccounts_AddingNewDataItem" ShowInsertRow="False" RowDetailsVisibilityMode="Collapsed" Pasting="gridViewAccounts_Pasting" Copying="gridViewAccounts_Copying" CanUserResizeColumns="True" AllowDrop="True">

This may be related to another problem I am experiencing.

I am using a slider with selectionRange enabled as well as well as with visible handles. In the control template I can see that those arrow buttons are reapeatButtons, however they seem to have behaviour of the standard button (repeat doesn't work). So if I press and hold the arrow key, it doesn't seem to fire multiple click events.

Hello,

I've got a WPF application with  radmenu and a radgrid. (v.2010.3.110.35)
When I click on a row in te grid, the menu-items are disabled in the main-menu, when I drag a column from the grid on the grouping header and remove it again the menu-items in de main menu are enabled again.

What could cause this problem?

I am using the code below to create the menu.
