Hi,

I am new to using Telerik Framework. I am trying to write automated tests for a WPF application that we have, but I keep getting a null reference exception when I try and use the code described in this page http://docs.telerik.com/teststudio/testing-framework/write-tests-in-code/silverlight-wpf-automation-wtc/wpf-ui-automation. 

This happens in the line that is launching the application 'WpfApplication foo = myManager.LaunchNewApplication(@"C:\Users\e-ddcr\Documents\GAV\2.0\gav-app\PokeMoon\PokeMoon.Startup\bin\Debug\PokeMoon.Startup.exe"); '. Unfortunately the error does not seem to give me very much to go on, and I could not find anything online that helped resolve the issue. 

Below you have the details of the error and my code. Any help would be hugely appreciated.

Many thanks,

Error:

It looks like the RadPropertyGrid doesn't supply an ITypeDescriptorContext when invoking TypeConverters on a property (the context is alwayas null). This makes it impossible to use custom type converters that do things like provide custom standard values. Is this a known limitation, are there plans to add support for this?

Thanks

I've used your tutorial "Templating the GroupHeaders topic" to create a custom GroupHeaderContentTemplateSelector.

How do I make each group header height to stretch to the content of the header template? For example the first group header height is 200px, the second 300px, the third 80px. Currently all group headers have equal height. Is this possible?

Hi,

I am using Rad Timebar for showing charts. In that I added 6 intervals year,quarter,month,week,day,hour scrolling upto month level only. When I remove month interval it is scrolling Quarter level. I would like to scroll both month as well as quarter, means after month scrolling need to show quarter level on the top of the head.

Swamy.

I have a CollectionEditor called Pictures which has key value pairs as items. The value is a path to an image file. My template for CollectionEditor looks like this:

<Style TargetType="telerik:CollectionEditor">
        <Setter Property="ItemTemplate">
            <Setter.Value>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=Bit}" />
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I would like to add a browse button to the 'content' field. Is that possible?

Hi, it's possibile not delete the appointment then the user press the key Delete ?

I have using the event PreviewKeyUp, but not work.

if you have any solution...thanks

Hi,

  The Collection Editor is part of RadPropertyGrid defined below:
   

   Please see attached picture showing the desired output.

When I select a row in a RadGridView (as shown below)

    private void gridviewServiceTraceWatchList_SelectionChanged(object sender, SelectionChangeEventArgs e)
        {

            txtBillTo.Text = e.AddedItems[0].ToString();

        }

I get: “ServiceTrace.WPFApplication.CIPService.ServiceTraceWatchListData”

I’ve tried everything I know and looked and nothing works. Can anyone tell me what I’m missing? It has to be simple and I'm overthinking it. I just want to get a single field item from a row of data.

Thanks in advance.
