separate context menu for grid headers

Hi,

I need separate context menu for the grid rows and the grid headers.

I defined the rows context menu in the xaml like this:

<telerikGrid:RadGridView x:Name="ordersGrid" AutoGenerateColumns="False" DataLoadMode="Synchronous" >

<Navigation:RadContextMenu.ContextMenu>

<Navigation:RadContextMenu Opened="RadContextMenu_Opened" ItemClick="RadContextMenu_ItemClick">

<Navigation:RadContextMenu.Items>

<Navigation:RadMenuItem Header="Update Order" />

<Navigation:RadMenuItem Header="Cancel Order" />

<Navigation:RadMenuItem Header="View Details" />

</Navigation:RadContextMenu.Items>

</Navigation:RadContextMenu>

</Navigation:RadContextMenu.ContextMenu>

and i defined in the code the context menu for the headers.

The problem is that the main context menu overrides the header context menu. I even try to remove it in the loaded event but it didn't help:

void ordersGrid_Loaded(object sender, RoutedEventArgs e)

{

GridViewHeaderRow headerRow = ordersGrid.ChildrenOfType<GridViewHeaderRow>().FirstOrDefault();

IEnumerable<GridViewHeaderCell> cells = headerRow.Cells.OfType<GridViewHeaderCell>();

/**remove the default menu from the header in order to ser a separate menu for header**/

foreach (GridViewHeaderCell cell in cells)

{

var x = cell.ContextMenu;

RadContextMenu.SetContextMenu(cell, null);

}

GridViewHeaderMenu gvhm = new GridViewHeaderMenu(ordersGrid);

gvhm.InitializeMenus();

}

How can i achieve it?

Thanks,

Ofer

How can I catch invalid entries as ValidationError?

Hello,

I have the following problem: I have a form with a RadDatePicker in it. Everything works fine, but when I enter an invalid date into the entry field of the picker, the date is just resetted or the entry field of the picker is empty. I would prefer to see the defined ErrorTemplate instead.
I tried to catch this by adding ValidatesOnError to the Binding in the XAML file but it doesnt work.

So: How can I catch it if the user enters an invalid value to the entry field?

Best Regards,
Jerma

ReadOnly Cell and GridViewCell.PreviewEditStartEvent

I'm using RadGridView and need to prevent editing for some cells not at the column level, but based on the row and column.

I've tried using ReadOnly Cell and GridViewCell.PreviewEditStartEvent as described here:

http://www.telerik.com/community/forums/wpf/gridview/set-read-only-property-for-cell.aspx

It appears in the version I am using the PreviewEditStartEvent does not exist. Am I missing something? Was this removed?

I have version 2009.3.1208.35.

Thanks,

Mike

New to WPF/DataBinding

How do I bind a GridView to a dataset, is it even possible? I looked iin the guide book and they all seem to binding via the code and in the ASP.NET version you can just link it to the SQL datasouce you created. (Again dont know much of this WPF world)

Im use to the ASP.NET RadGrid and binding options but Im trying to see if I can get one of my larger applications to run in WPF.

Im using Q3 WPF and VB. I added a DataSet and have the query I want in it. (I just left it the default "DataSet1.xsd" with all the default values for testing.)

Unable to drag Telerik controls from Toolbox onto designer

I'm unable to drag Telerik controls from the VS Toolbox onto my WPF design. When I try, I get the classic circle with a slash through it, generally used to indicate an operation is prohibited. I can drag regular MS controls from the toolbox onto the designer but not Telerik controls. Any suggestions for resolving this?

Thanks,
Scott

Grid stealing focus when row is added

How can I prevent the grid from stealing focus when a new item is added to the underlying collection?

For example, I have two seperate windows, one which displays the grid, another through which the user may add new rows to the grid. I would like focus to remain on the add window when the user adds a new row, but the grid by default seems to be setting focus to the first editable cell in the new row.

Thanks
