SaveLayout problem when RadDocking within RadTabControl

Hello,

I am really hoping that someone can help me. I am new to the Telerik controls and am having an issue with the saving of the layout of a RadDocking control when it is embedded within a RadTabControl's ContentTemplate.

I am saving the layout to a file so I can verify that it is being formatted correctly, however the SerializationTags are not getting output to the file.

Here is a snippet of the XAML to show that I am setting the SerializationTag for my RadDocumentPane:

<telerikNavigation:RadTabControl.ContentTemplate>

<Grid>

<radDock:RadDocking x:Name="ResultDocuments" Background="Transparent"

<radDock:RadDocking.DocumentHost>

<radDock:RadSplitContainer SizeChanged="SplitContainer_SizeChanged" >

<radDock:RadPaneGroup Name="RadDocumentGroup" Background="Transparent"

radDock:RadDocking.SerializationTag="DocumentGroup">

<radDock:RadDocumentPane

DataContext="{Binding DataContext,ElementName=ResultDocuments}"

Margin="0,0,0,-5" Name="DocumentPane" Title="Documents"

radDock:RadDocking.SerializationTag="DocumentPane"

HorizontalContentAlignment="Left" CanUserClose="False">

Here is a snippet of the output file I am getting:

<Items>

<Items>

</Items>

</RadPaneGroup>

</Items>

</RadSplitContainer>

</DocumentHost>

Finding an element in a GridViewColumn CellTemplate

It is necessary to find a specific named element in the CellTemplate of a GridViewColumn.

There is a GridViewColumn defined like this:

<GridViewColumn Header="column 1">

<GridViewColumn.CellTemplate>

<DataTemplate>

<TextBox x:Name="txtcontent"/>

</DataTemplate>

</GridViewColumn.CellTemplate>

</GridViewColumn>

It is possible to find an element in a DataTemplate by getting the ContentPresenter where the DataTemplate is applied, and using the FindName method of the DataTemplate to find a specific element.

DataTemplate celltemplate = column.CellTemplate;

ContentPresenter contentpresenter = ...

TextBox txtbox = (TextBox)celltemplate.FindName("txtcontent", contentpresenter);

How can you find the ContentPresenter where the GridViewColumn CellTemplate is applied?

RadMap ItemsVirtualization example throws 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll

Hi I just ran the Rad Map ItemsVirtualization example from the demo code and I notice certain sluggishness when running the map. Looking at the output window of Visual studio I've noticed a large amount of the errors

A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll
Any idea why are those thrown?
And also if I increase the density of the grid like the next line of code

 this.dynamicLayer.ZoomGridList.Add(new ZoomGrid(2 << 13, 2 << 13, 13));
the number of the errors increases tremendously.
EDIT>> I looked more into the call stack and this is the error thrown




System.ArgumentOutOfRangeException occurred Message=The added or subtracted value results in an un-representable DateTime.
Parameter name: t
  Source=mscorlib
  ParamName=t
  StackTrace:
       at System.DateTime.op_Addition(DateTime d, TimeSpan t)

How to target BeginInsert to detail level of hierarchy?

I have a master/detail hierarchy implementation (see attached picture).

I have coded to RowLoaded event to set GridViewRow.IsExpandable = false for master rows whose detail collection is empty. I wanted to visually show that there were no associated details, and save the user from clicking on the (+) expander control needlessly. I have set ShowInsertRow="True", and my preference is to keep ShowInsertRow="False". Instead, I would like to have a button (elsewhere in the UI) to call the BeginInsert() method. However, how do I target the detail level - particularly if the master row has an empty detail collection?

Nested grid view's context menu

Hi!

I have a grid which has another grid in its row details. Both grids should have a context menu, however, if I right-click in the row details grid, it shows me the context menu of the parent grid. Is there a way to have it show the child grid's context menu when right-clicking on the child?
