After installing, I am not able to browse through the controls in the WPF Demos program. The application is crashing on each invocation of a control, just after downloading the sample.

Why?? How can I fix it?

Regards,
Wolfgang

Custom snapping & rotation stepping

Hi,

In the diagraming component - is there a way how to do custom snapping? E.g. I have several components that can be joint together (say pipes) and if they are close enough with their correct edges they will snap. Something like the existing functionality IsSnapToItemsEnabled but not to edges but to custom points on an item...

Also - I would like to enable rotation only by steps of 90 degrees... Is there an easy way to achieve this?

Thanks,
Jarda

RadRibbonView Backstage issue within PRISM region

Hello,

I have placed a RadRibbonView inside a prism region.

<ItemsControl x:Name="RibbonRegion" cal:RegionManager.RegionName="RibbonRegion"></ItemsControl>

Neither the region nor the RadRibbonView have an explicit Height set. Clicking the ApplicationMenu Button, to expose the Backstage, will cause the issue described in the attached image.
The Backstage won't expand to ocuppy the whole window size, it will instead look as though it's trapped inside the region.

I came up with a temp workaround: Adding Height="143" to the region, and adding in the code behind:

MyRibbonView.Height = SystemParameters.WorkArea.Height;

will solve the problem, but will cause unexpected behavior in, for example, the help ScreenTips.

I found a post claiming that adding

<ItemsControl.ItemsPanel>
    <ItemsPanelTemplate>
      <WrapPanel />
    </ItemsPanelTemplate>
  </ItemsControl.ItemsPanel>

inside the region will make it expand when needed and solve the problem, but it does not, and makes the whole region content disappear, also.

Thanks.

No groupable column doesn't work?

It seems if I have a column with IsGroupable set to false, I can still drag and drop it to the group panel and grouping still works.

I know this can be workaround by handling and canceling the Grouping event, but are you guys planning a fix for this?

Thanks

Modify Style of Validation Border of a Cell

When there's a validation error on a cell, I want the cell background to be red and the tooltip displaying the error to show any time the mouse is over any portion of the cell. This should replace the red border with small red triganle in the uppper right of the cell.

I am using 'InViewMode' for the ValidatesOnDataError property.

What's the best way to accomplish this?

Programmatically retrieve selected row values from radgridview

Hello,
I'm dealing with a radgridview and I'm in trouble while trying to retrieve row values from a radgridview.

I'm using telerik wpf control q2 2012.

My gridview is named Radgridview1 and has 5 colums (named "ID", "name", "surname", "address", "city")
I know I can retrive, for example, the value of the colum "ID" of the selected row using this code:

Dim myvalue As String = (RadGridView1.SelectedItem).ID

I have an array containing names of my five columns. I want to cycle my array and retrive values of each column of the selected row.

To do this I should be able to replace ".ID" in my code above with a variable retrievd from my list/array. How I can do this?

How I can replase the phisical name of the colum with the value of my string variable?

Anyone has an example?

King Regards

Unable to apply text selection and move cursor behavior in non-readonly GridViewDataColumn, using Keyboard keys.

I have a GridViewDataColumn where I can enter text in the cell, but behavior for the text entered, like:
1. Selecting text using Shift + Left/Right arrows,
2. Hold down Left/Right arrow, the cursor should move continuously until the key is released,
3. Similarly for Shift + Shift + Left/Right arrows,
does not work.

I want to know what events need to be handled to get the above behavior?
