Hi,

I have a grid that i declare in xaml but i want to define the child columns of the hierarchy (not autogenarated).

How can you do that?

My code:

Hi,

Is there a way to know when there's an other record selected?

Because i can't find an event like SelectedIndexChanged.

regards

I have used the following code to associate a table value to a button.  I would like to do a similar thing to with a textbox, but I keep getting a NullReferenceException.

<Telerik:GridViewCell Foreground="#FFFFFFFF" Width="80" ColumnName="submittal" TextBlock.FontSize="16" Margin="770,0,0,0" HorizontalAlignment="Left">
<Telerik:GridViewCell.Template>
<ControlTemplate>
<Button Click="Button_Click" Background="Transparent" Foreground="White" ClickMode="Press" Tag="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}" AllowDrop="True" >
<TextBlock Width="75" Text="Submittal" />
</Button>
</ControlTemplate>
</Telerik:GridViewCell.Template>
</Telerik:GridViewCell>
What is wrong with:

<

Telerik:GridViewCell Foreground="#FFFFFFFF" Width="80" ColumnName="submittal" TextBlock.FontSize="16" Margin="770,0,0,0" HorizontalAlignment="Left">
<Telerik:GridViewCell.Template>
<ControlTemplate>
<TextBox Text="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}" AllowDrop="True" >
</TextBox>
</ControlTemplate>
</Telerik:GridViewCell.Template>
</Telerik:GridViewCell>
 
?

Hello,

When your RadControls for WPF will be released, will it be released with source code?

Hi,

After restyling the grid view items control to take out the group panel I get an error when clicking on cells:

  

My control template is as follows:


Have I done something wrong or is this a bug?

We have an issue with the column drag&drop mechanism.

This issue happens when you drag and drop a column and then change the data source.

After this, no columns are displayed in the grid. We are adding the column definitions ourselves (they are re-generated when the data source changes) and we know that it works when changing the data source without performing column drag / drop.

Is this a known issue?

Kind regards,

Will Holley.

We are using the RadGridView to present paged data and would like to intercept the Sort events and plug in our own mechanism to sort across the entire data set. Is there a straightfoward way to do this?

Another requirement is that we need to disable sorting on some columns - is this possible?

Kind regards,

Will Holley

When the grid first loads and we have our column widths set to Auto, the column widths are correct. However, when we change the itemssource property to point to a different datasource (which loads it's data asyncronously), the widths do not update.

Is it possible to force the columns to re-evaluate their widths? Calling AutoFitColumns via reflection doesn't seem to work (!).

Kind regards,

Will Holley

Hi,

We are just experimenting with the RadGridView in the WPF controls and have found that when we bind to an observable collection, CollectionChanged events cause the grid to throw an exception:

"This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread."
   
   at System.Windows.Data.CollectionView.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args)
   at Telerik.Windows.Controls.Core.Data.VirtualizingRecordCollection.OnCollectionChanged(NotifyCollectionChangedEventArgs e)
   at Telerik.Windows.Controls.Core.Data.VirtualizingRecordCollection.Reset()
   at Telerik.Windows.Controls.Core.Data.VirtualizingRecordCollection.set_RealRecords(IList`1 value)
   at Telerik.Windows.Controls.Core.Data.RecordManager.RecalculateGroups()
   at Telerik.Windows.Controls.Core.Data.RecordManager.ResetRecords()
   at Telerik.Windows.Controls.Core.Data.RecordManager.OnSourceCollectionChanged(Object sender, NotifyCollectionChangedEventArgs e)
   at Telerik.Windows.Controls.Core.Data.RecordManager.ReceiveWeakEvent(Type managerType, Object sender, EventArgs e)
   at System.Windows.WeakEventManager.DeliverEventToList(Object sender, EventArgs args, ListenerList list)
   at System.Windows.WeakEventManager.DeliverEvent(Object sender, EventArgs args)
   at System.Collections.Specialized.CollectionChangedEventManager.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs args)
   at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e)

This looks to be a bug in the grid as we haven't experienced this with the other WPF grids we tried. Do you know of a work around?

Many thanks,

Will Holley
