Hi Pavel,

So you have a solution for this issue ?. I had a similar problem and below is my code:

<

 

 

Telerik:GridViewComboBoxColumn x:Name="cmbFormSections" Header="FormSection" SelectedValueMemberPath="Id"

 

 

 

DisplayMemberPath="Wording" DataMemberBinding="{Binding FormSection.Id}" />

 

I am population my GridView using this code in my .cs file:

GridViewComboBoxColumn

 

 

cmbFormSections = this.View.radGFormSubSections.FindName("cmbFormSections") as GridViewComboBoxColumn;

 

cmbFormSections.ItemsSource = FormSectionsCollection;

When i click in another ceel after selecting a value in cmbFormSections, my selected values disappears.

This is show stopper for me. Please let me know where i am going wrong.

Thanks,

Hi Hemal,

Did you get a solution for this issue. I had the same problem n i am setting all the values correctly.

Please let me know, if you get any reply from the Telerik team.

Thanks.

Hi Victor,

Usually this happens when there is a type mismatch between the type of the ID property - for example in the source of RadGridView it is a string and in the source of the combo it is an integer.

At first glance your code seems ok .
Can you please send us your project( or just  a small project resembling the issue ) . I will gladly have a look to see what may cause the problem and provide the neccesary fix.

Best wishes,

Hi Pavel,

Thanks for your reply. I have solved the issue last night and forgot to send you an email. I was setting the Selected Value to the ID and it was expecting an object as i was using EntityFramework.

Anyways thanks for the solution.
