I have a Silverlight RadGridview in which i have a cell which contains the RadComboBox, the celltemplate is as below,
<telerikGrid:GridViewDataColumn.CellTemplate>
<DataTemplate>
<telerikInput:RadComboBox Margin="2" VerticalAlignment="Center"
IsEditable="True" ItemsSource="{Binding SchoolGender}"
SelectedItem="{Binding SelectedGender, Mode=TwoWay}">
</telerikInput:RadComboBox>
</DataTemplate>
</telerikGrid:GridViewDataColumn.CellTemplate>
I am trying to bind the ItemsSource to "SchoolGender" which is a ObservableCollection<string>. Also i am trying to bind the SelectedItem to "SelectedGender" which is a string property.
Issues:
1) The binding works fine for some rows and does not work for some rows.
2) When i scroll the grid using the vertical scroll bar, the selected item of the combobox becomes null.
Is this a known issue? Is there any workaround for this?

You may take a look at the following forum thread that demonstrates how to define RadComboBox within GridViewColumn's CellTemplate, please follow this link.

The example solves my problem but raises another issue.
The problem is, whenever i scroll the grid, the SelectedGender property (which is bound to the SelectedValue of the ComboBox) is set for the number of records which are in the view, which is not an acceptable behaviour.
Is this a known issue? Please let me know the workaround for this.

We're not aware of such an issue with RadGridView and SelectedValue property of RadComboBox. Can you please send us a simple project demonstrating the problem? Thanks in advance

Yes, the problem persist. I will create a sample illustrating this, but currently i have other priorities to work on, i will send a sample whenever possible.
