Hi Team,

I have used the RadImageEditor to show the tif images in ListView. When clicking on RadImageEditor, the Selection is not processed in ListView, it is working fine when clicking over TextBlock. How to skip the mouse operations in RadImageEdiotr? Please refer the below code snippet.

Regards,

Antony Raj

I am building a WPF form and using Telerik WPF 2017.1.117.  I have a pdf loading fine from an external URL, but when I call the .Print command nothing is spooled and no errors are generated.  After searching as much as I could, I can't find anything that would show why what I have is not working.  Thanks for any help you can provide.

using (WebClient client = new WebClient())
{
using (Stream ms = new MemoryStream(client.DownloadData(Properties.Settings.Default.URL + badgeURL)))
{
MemoryStream mStream = new MemoryStream();
mStream.SetLength(ms.Length);
ms.Read(mStream.GetBuffer(), 0, (int)ms.Length);
this.radPDF.DocumentSource = new PdfDocumentSource(mStream);
}
}

this.radPDF.Print(new PrintSettings("Document 1", true));

I've encountered a strange issue regarding the GridViewPinButton visibility in RadGridView.

My only wish is to disable this functionality- to set the GridViewPinButton visibility to collapse in every row in RadGridView.

Now, I have one place where it works great and another one where I can see this button while I'm hovering the rows.

In both places I haven't written any code concerning the GridViewPinButton , and in both cases the visibility of the button is set to collapsed.

The only difference I can see is in snoop (images are attached):
When it works well, GridViewPinButton does not have any child elements, while it has them in the second case.

When I click the button, I get the error:
Could not find any resources appropriate for the specified culture or the neutral culture.  Make sure "Telerik.Windows.Controls.GridView.Strings.resources" was correctly embedded or linked into assembly "Telerik.Windows.Controls.GridView" at compile time, or that all the satellite assemblies required are loadable and fully signed.

Hi,

I have a treeview that uses the datatemplate shown below. It has a context menu. I'd like to be able to disable or hide certain items depending on which node in the tree they click on. Is this possible? If so, can someone share some example code of how to do this in an MVVM fashion?

Thanks ... Ed

So, I have a RadDock setup. In the hosting main window there is a radmenu followed by a  radtoolbar where I have a toolbarbutton for saving. Below that I have a raddocking that has a pane that hosts my usercontrol that contains, among other things a the RadDateTimePicker shown below. It works great except in one odd condition. If the txtClosedDate has a valid value and the user blanks it out and then hit's the button in the toolbar without clicking or tabbing to another field, the null value is not bound back to the source and my viewmodel receives the original date value instead of null. If, however, the user goes to any other field on the user control, thereby forcing a lost focus event the correct binding happens. I have hacked around the problem with the following code, but I think you boys need to fix this on your side.

Thanks ... Ed

Hi,

I have a tree that is bound and load on demand.

For simplicity say I had:

Hi,

Is there a quick way to expand a branch to the leaves programmatically for a load on demand scenario?

Thanks ... Ed

telerik:RadProgressBar x:Name="pb" Width="220" Height="15" Minimum="0" Maximum="100" Value="10" Margin="40,4,0,4" />

Upto say value=30 i want grey color and above that point i need default color.

Please suggest/provide sample code.

Hi,

I have two questions:

1- is it possible to set the default value of the zoomcontroller to "automatic" instead of 100 %?  if possible in XAML, or in code-behind is necessary

2- is there a way (documented or code snippet) so I can filter the export format (i.e.: I only want PNG files)

Thanks

Hey,

Is there way to disable cutting letters from PDF? When I am loading PDF file it is cutting polish words, is there any chance to avoid this?
