Hi Telerik Team!

I’m evaluating your WPF control bundle for one of our new applications and have some problems regarding the backstage tab in combination with a WebBrowser control in the content area of my prototype. Although the backstage tab is active, the WebBrowser control is visible and overlaps my backstage-content. Is there a way how I can solve this problem?

Best regards,

Dominik

#endregion

// Click 'btn' button

Mouse.Click(uIBtnButton, new Point(15, 8));

RadPanelBar Question

<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinitions Width = "300" />
<ColumnDefinitions />
</Grid.ColumnDefinitions>
<telerik:RadPanelBar Grid.Column = "0" VerticalAlignment = "Stretch" ExpandMode = "Single">
<telerik:RadPanelBarItem>
<telerik:RadPanelBarItem.Header> <TextBlock Text = "Panel 1" /> </telerik:RadPanelBarItem.Header> <StackPanel VerticalAlignment = "Top">
<telerik:RadButton Name="Button1" Content = "Customer" Height = "50" />
<telerik:RadButton Name="Button2" Content = "Order" Height = "50" />
</StackPanel>
</telerik:RadPanelBarItem>
</telerik:RadPanelBar>

<ContentControl x:Name = "ContentContainer Margin = "8" Grid.Column = 1" />
</Grid>

Well, as you see I have RadPanelBar. When I select RadPanelBarItem I want to load some user control in ContentControl. In this example when I click "Button1" I want to load in ContentControl "Customer" UserControl, which I created, when I click "Button2" I want to load "Order" UserControl.

Can you help me how to do that??

Getting compiler error since upgrading to VS 2012

I'm using version 2012.3.1129.40 of the Telerik controls for WPF. I have a RadGridView control in one window which uses the CountAggregateFunction:

<telerik:SumFunction ResultFormatString="{}{0:n0}" />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

When I was running VS2010, this compiled fine. However, after upgrading to VS 2012, I get the following error for both of the Aggregate Functions:

The specified value cannot be assigned to the collection. The following type was expected: "AggregateFunction".

The thing is the compiled code runs fine. It's just an error that shows up in the design pane and doesn't stop the compile code from running.

How do I fix this problem?

RadDropDownButton loses Enter/Space behavior after multiple clicks

Hello,
I'm seeing an issue with the RadDropDownButton and am wondering curious if there is a work around for my scenario. When focus is on a RadDropDownButton pressing 'Enter' or 'Space' normally causes the button to display the DropDownContent; what I'm seeing is this keyboard functionality stops working after the following steps.

1. User clicks the RadDropDownButton. This causes the DropDownContent to display as expected.
2. User clicks the RadDropDownButton again. This closes the DropDownContent to hide as expected and focus is once again on the button itself.

Unfortunately it is at this point that 'Enter' and 'Space' seem to no longer work. Even after tabbing off of the control and returning the keyboard functions do not work. Interestingly pressing 'Space' actually changes the button visual to the 'Pressed' state but the DropDownContent is not displayed. Any ideas to get the keyboard functionality work would be greatly appreciated. We are currently using assemblies version 2012.2.912.40. Thanks much for any feedback!

Below is the code for a small test app that exhibits the behavior outlined above.

Very long time on 10000 points

Hi !

I'm trying telerik charts and I wanted to test the performance. I saw the sample with 15000 points and I wanted to do the same with much more. Unfortunately, my computer got very hard to print a 10000 points line. I guess something is wrong with my code compared to the sample one but I don't really realise what.

class DataListViewModel : ViewModelBase

{

private RadObservableCollection<int> dataList;

private Random random = new Random((int) DateTime.Now.Ticks);

public DataListViewModel()

{

this.Data = this.FillRandomlyList();

}

public RadObservableCollection<int> Data

{

get { return dataList; }

set

{

if (value != dataList)

{

dataList = value;

this.OnPropertyChanged("Data");

}

private RadObservableCollection<int> FillRandomlyList()

{

var res = new RadObservableCollection<int>();

for (int i = 0; i < 10000; i++)

{

res.Add(random.Next(500));

}

return res;

}

Does someone have an idea ?

getting row as gridviewrow don't work?

Hi

I am trying to show the detailvisibility from a row after filling up the gridview.
but the row i receive row=... is always nothing.
I found the code to retrieve the row in an other forumthread.
but it is not working.

I work with the latest version of the controls.

Dim dt As datatable

dt = getdatatable.defaultview

Me.radDataPager.Source = dt

radDataPager.MoveToLastPage()

Dim row As Telerik.Windows.Controls.GridView.GridViewRow

row = Me.radGridView.ItemContainerGenerator.ContainerFromIndex(radGridView.Items.Count - 1)

row.DetailsVisibility = Visibility.Visible

Thanks
