Is RadTreeMap Still Supported?

I can't for the life of me get anything to show up in either the designer or at runtime. It's just blank, as if the control is not there. I'm using 2014.1.224.45 with implicit themes.

Change FontSize of property name in RadPropertyGrid

Hello.

How can I change size of font of names of properties in RadPropertyGrid? I have AutoGeneratePropertyDefinitions="True", so everything generates automatic. Furthermore I would like to do it in xaml file if it is possible.

I have just tried to set FontSize for the RadPropertyGrid and it didn't work. Moreover I think there is different sizes for different text fields in RadPropertyGrid.

I have attached a picture of what I am talking about.

Thank you for help,
Ilya.

Grouping now working when exporting to Excel

Hi there,

We're trying to get grouped RadGridView content exported but neither the CSV Export (either via Export() or ToCsv()) nor Excel Export via RadSpreadSheet and XlsxFormatProvider is giving us the grouping we have in the UI.

Specifically we're missing the group headers we can see in the UI -
With the appropriate flag we can have the group footers in the CSV.. but that's not giving us the headings we're looking for (the ones that can be seen in the UI).

How can we export the current grouping to CSV and Excel whilst preserving the grouping headers?

Thanks,
Jay

[Solved] Binding a DataSet to a GridviewComboBoxColumn

Hello,

I've searched for a while but didn't find anything useful about it.

I've a dataset, filled with an SQL query which contains a table of many records, and a gridView with a comboboxcolumn. I try to bind my comboboxcolumn with my dataset, but it only displays the first row, in my whole column. For example, if I have 400 records, it displays 400 times the first record.

Here's my code in my .xaml :

<telerik:RadGridView HorizontalAlignment="Left"

VerticalAlignment="Top"

ItemsSource="{Binding dataSetCameras}"

etc, and :

<telerik:GridViewComboBoxColumn Header="Cameras"

UniqueName="Camera"

DataMemberBinding="{Binding reference}"

DisplayMemberPath="Camera"

SelectedValueMemberPath="Camera"

HeaderTextAlignment="Center"

EditTriggers="CellClick"

Width="*">

<telerik:GridViewComboBoxColumn.ItemTemplate>

<DataTemplate>

<Grid>

<Grid.RowDefinitions>

<RowDefinition />

</Grid.RowDefinitions>

<TextBlock Grid.ColumnSpan="2" Text="{Binding reference}" />

<StackPanel Grid.Row="1" Orientation="Horizontal">

<TextBlock Foreground="#FF356EA6" Text="{Binding sold}" />

<TextBlock Text=", " />

<TextBlock Foreground="#FF356EA6" Grid.Column="1" Text="{Binding broken}" />

<TextBlock Text=", " />

<TextBlock Foreground="#FF356EA6" Grid.Column="2" Text="{Binding stolen}" />

</StackPanel>

</Grid>

</DataTemplate>

</telerik:GridViewComboBoxColumn.ItemTemplate>

And in my .cs :

((GridViewComboBoxColumn)this.gridViewCameras.Columns["Camera"]).ItemsSource = datas.dataSetCameras.Tables;

Did I miss something ? And yes, I'm sure that my dataset is filled with the right values.

Thanks for your help !

Not able to automate actions on ListItems in Filter Properties window of grid.

Hi Team,

We are trying to automate actions on ListItems present in filter properties window of Rad Grid View with VS2012 Coded UI Test Framework but we arenot successfull in it.
Name property on the listitems is used for its idetification but this name seems to be same for all the list items present in the list(i.e. "Telerik.Windows.Controls.GridView.DistinctValueViewModel").

Can you please implement ToString on the listitems to consider CheckBox name[which is present inside the listitem] ?

Regards,
Bhagavan

[Solved] Width="*" for a GridViewDataColumn with Grouping causes freeze

I've run into an issue where GridView will freeze when trying to auto-adjust column widths to the available window if a group is applied. I have a series of columns, most of which are Width="Auto", but one of which is Width="*". If I resize the window to allow the * column to expand, then try to reduce the width while a grouping is applied, the horizontal scroll bar flashes and the application freezes. Sometimes it comes back, sometimes it doesn't. Sometimes switching to another window and back seems to help, sometimes it doesn't.

Pausing the debugger while this is occurring (which is only possible some of the time; sometimes Visual Studio is frozen as well) tries to open the file:

c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Controls\GridView\GridView\GridView\ScrollViewer\GridViewScrollViewer.cs

The call stack is:
[External Code]
Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Controls.GridView.GridViewScrollViewer.MeasureOverride(System.Windows.Size availableSize) Line 202 + 0x25 bytes C#
[External Code]

The problem does not occur if the * column is switched to Auto, or if the Grouping is not applied. It also doesn't seem to happen if no vertical scrolling is necessary.

I am using 2013_3_1209, but have verified the problem still occurs with 2014_1_0224. Below is a simple application which exhibits the problem when you try to reduce the width of the window.

Is there any known way to work around this issue using other settings while achieving the same effect?
