Hello,

I have placed a RadRibbonView inside a prism region.


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.

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

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?

I want to be able to bind the IsExpanded property of the item displayed in the RadTreeListView to a property on the bound model, how can I achieve this?

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

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?

I'm trying to bind some data from an SQL Server database to a RadGridView.  I'm grabbing the data and storing it in a dataset and I've tested this to see that the data is coming in properly.  I've tried setting the ItemsSource and the DataContext with:
Grid.ItemsSource = ds.Tables[0].DefaultView;               

But the data never loads in.  This is my XAML code:

 <telerik:RadGridView Name="Grid" Grid.Row="2" Grid.ColumnSpan="3"  HorizontalAlignment="Center" VerticalAlignment="Bottom"
                             AlternateRowBackground="AliceBlue" SelectionMode="Multiple"
                             AutoGenerateColumns="False" MinHeight="300" MinWidth="800"  CanUserResizeColumns="True" CanUserResizeRows="True"
                             FilteringMode="FilterRow"  IsFilteringAllowed="True"  CanUserSortColumns="True" GridLinesVisibility="Both"
                             DataLoadMode="Asynchronous"  >
            <telerik:StyleManager.Theme>
                <telerik:Windows8Theme/>
            </telerik:StyleManager.Theme>
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Width="40" Header="Add" DataMemberBinding="{Binding Add}" IsGroupable="False" IsFilterable="True" >                                
                    </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn Width="75" Header="Qty"  IsGroupable="False" IsFilterable="True">
                </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn Width="75" Header="Catalog Number" DataMemberBinding="{Binding Catalog_No}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="200" Header="Description" DataMemberBinding="{Binding Description}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="Price" DataMemberBinding="{Binding Price}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="Min" DataMemberBinding="{Binding Min}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="# avl" DataMemberBinding="{Binding Available}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="Size" DataMemberBinding="{Binding Size}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="Color" DataMemberBinding="{Binding Color}" IsGroupable="False" IsFilterable="True"/>
                <telerik:GridViewDataColumn Width="75" Header="Style" DataMemberBinding="{Binding Style}" IsGroupable="False" IsFilterable="True"/>
            </telerik:RadGridView.Columns>
            
        </telerik:RadGridView>

So am I doing something wrong here or do I have to change the way I'm loading in the grid data?  In this case, it would not be impractical to load the data in and fill the grid view by looping through the data, but I'm going to be using the gridview in other places as well where I'll have to load in too much data for that to be a practical solution.

I am having a problem with the grouping functionality of the WPF Control RadGridView.   Dragging and dropping the column name to the "Drag a column header and drop it here to group by that column" area does not work.  Nothing happens, no errors.   The "IsGroupable" setting for each column is checked.  I tried explicitly setting it in the xml, and it had no effect.  The ShowGroupPanel
on the RadGridView is set.   According to the documentation that is all that is needed.

Here is the XAML file.

The "ThreadCollection" is an ObservableCollection.

Adding the following, displays the groups.  They are grouped correctly.  All seems to work unless you drag the group name off of the group bar, or use the close icon on the group name.  The GridView will be correct, but you can not get the group back again.

           
<telerik:RadGridView.GroupDescriptors>
   <telerik:GroupDescriptor Member="Target" />
   <telerik:GroupDescriptor Member="JobStatus" />
   <telerik:GroupDescriptor Member="Servername" />
</telerik:RadGridView.GroupDescriptors>

In an attempt to debug, I added event hanlders for Grouped and Grouping events.  They never got called on the drag and drop to the group bar.  The only time they were called is when the GroupDescripitors were in place, and then only when the groups were removed from the bar. 

Using Telerik version 12.1.326.0
VisualStudio 2010
.NET 3.5
C#
Windows Server 2003 R2

Any suggestions would be appreciated.

I have followed the project at http://www.telerik.com/help/silverlight/raddatafilter-how-to-create-custom-filter-editors.html to create a solution that uses a RadComboBox as a custom filter for some fields in a RadDataFilter.

I have been unable however to get the value selected in the RadComboBox to update the underlying FilterDescription, with the Filter always ending up with 'Status isEqualTo <unset>' after selecting an item in the combo box.

I am sure I have followed the project correctly, and have the SelectedValue of the ComboBox bound to the Value property as below.



The only difference I can see to the example code is that I am using the RadDataFilter unbound. It is not bound to a DataGrid, I am setting my own ItemPropertyDefinitions and using the resulting FilterDescriptions in other parts of the project. Is there a way to check that the DataTemplate Value is getting set when the RadComboBox value changes, or do I need to force the FilterDescription to update somehow as it is unbound? Finally, if nothing else is there a way to manually set the Value or update the FilterDescription when the ComboBox value changes?

Thanks
