Hello.

I saw the post in 2013. At that time, it was impossible to implement.

Is it possible now? Putting something like "ItemsSource={bindg WorkBook}" in telerik:RadSpreadsheet and binding it with MVVM?

Even when called like this, a workbook and a worksheet are created and bound in the viewmodel, and modifications should be possible afterwards.

About 8years have passed. But there are not many posts.

If possible, ask for examples. Thanks.

I've download the `TelerikEditor` user control that exist on the GitHub repository of Telerik , I've called it on my project and it works fine , but the problem is that I got this warning , I'm searching for a way to remove it , How can I eliminate this warning message?

Note : All Dlls file ( assemblies ) are not trial version , I've checked them using : Property => Details => File Description

I have a custom control as the ToolTipTemplate in a GridViewDataColumn, and that is displaying perfectly.

However, when I set showduration with the ToolTipService or RadToolTipService ShowDuration property the duration stays at the default value.

How can I change the ShowDuration?

This is what my column XAML looks like.

I'm trying to set the selected items in  RadMultiColumnComboBox ( telerik control ) .

I know that selected item will return the object that is selected. Selected index returns the location in the list as an int.

For that reason I have used Selectedindex property and I got what I need if the SelectionMode = "single" using selectindex :

Unfortunately, this solution does not work for RadMultiColumnComboBox when SelectionMode is multiple, 

Is there any solution to get a list of selectedindex???

` md = new PersonController().GetPerson(mdl.id); int index = list.FindIndex(r => r.firstName.Equals(md.firstName)); mycbx.SelectedIndex = index;`

The browser render effect is blurry. As the attach image. The top is simple demo with wpf window and below is demo with radwindow.

The burrry effect is very obvious. I has tried with CEF FAQ, but not work.

Thanks.

I Drag a RadRichTextBox onto a UserControl, it asks me about options for the ribbon I turn off a couple of things, it creates it, I run and get this error at the UserControl's InitializeComponent();

''Set property 'Telerik.Windows.Controls.RadRibbonBackstageItem.Icon' threw an exception.'  

With an InnerException of 

IOException: Cannot locate resource 'images/modern/16/new.png'.

I checked to make sure I have all references for RadRichTextBox and the ribbons, yes they are all there

Any ideas???

Hi,

I would like to know how it's possible to detect any changes to the image in the editor?

Thank's

Lets say that in my RadCartesianChart I have a line series with values between -1 to 10.

If a point value is -1 I would like the opacity to change.

For example if it is red with opacity 1 I'd like it to change to red opacity 0.5 until the value goes above zero.

Is this possible?
