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

I am verifying that my view's property setter is indeed setting. However, the PropertyGrid editor is not losing focus. That is, I don't see the (somewhat) expected editor exit and change indicator, that sort of thing. I don't know if it's a Xaml issue or not. Not setting the values special otherwise: I have an INotifyPropertyChanged-based view into my domain model. Nothing spectacular there.

Worst case I'll go with something like a built-in string text editor. However, would be nice to fold in the validation for instance if Version.TryParse fails. How to go about doing this for the RadPropertyGrid for WPF please? Thanks!

Hi,

I've looked into this a good bit and can find nothing relevant.  Any threads touching on the subject are old and the API has since changed.  Basically I need to get access to an individual cell so that I can set a style for it.  I would expect there to be easy access to cells in the same way that columns can be accessed.

I'm looking for something like: 

myGrid.Columns[0].Rows[0].Style = myStyle;

A call like that would give me access to the top left cell of the grid.

Is there any way to do something like this?

Thanks,
Austin

Hi,
(Wrongly posted on gant forum)

I want to create this behavior:

I want to be able to select only full lines, and act on double click on the line -

currently I have 2 problems with this code:



1, when I double click inside the line - it selects the cell and not the line - I can only choose the line by clicking on the edge of the line.
    this code will return null: RecordType st = ((FrameworkElement)e.OriginalSource).DataContext as RecordType (unless I click on the edge)
2. when I click on the vertical scroll bar more than 2 times - it acts like selecting a cell ! - I need to interpreting clicking on scroll bar as clicking on the grid surface and not clicking inside the line.

How can I fix this ?

The question is closed.

I have a UserControl that contains a RadPropertyGrid and one of the property definitions for the RadPropertyGrid has the EditorTemplate set to a DataTemplate that contains a RadComboBox.  When I run the application, I get the following exception:

Could not load file or assembly 'Telerik.Windows.Controls.Input, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

If I add a RadComboBox to the UserControl, the RadComboBox displays just fine.

What am I missing?


Here is the XAML:


In the UserControl's Loaded event handler, I have code similar to the following:

I would like to be able to add a small shape (upward-pointing triangle) to the X axis of a bar chart under one of the bars.  The build report for Microsoft Team Foundation client shows something similar to what I have in mind (see attached PNG).

As a strategy, should I try to use a CartesianCustomAnnotation, and if so can that be used with a marker in a BarSeries?  How do I indicate that I want the triangle to sit under the bar marker?  Or should this be an annotation attached to the axis somehow, and if so how would I add an annotation to the X axis?

thanks,
Derek
