Hi,
I am working with RadGridView of Telerik
Source of the RadGridView is QueryableCollectionView (with OData)
Each column has filter option.
but the filter popup advance contains only "Select All" and not all the values of the column.
What should I do for see all the values in the filter advance?
Thanks
When working with OData, on the client, you have access only to the data fetched with the current query. If the currently queried data doesn't contain the corresponding distinct values you won't see them. However, in your case it seems that no values are displayed at all even when the values seems to be presented in the data.
This is not a known issue, but you can check the following. I can see that there is an additional text in the FilteringControl that says "Advanced". This is not part of the Telerik's FilteringControl so I will guess that there is a custom ControlTemplate that targets FilteringControl. If that is the case, you can double check the bindings in the ListBox element that shows the distinct values. Also, if you have a custom template and if it is based on an older version of Telerik, I suggest you to get the new one and replace the template, and then apply your customizations again.
If this doesn't help, I suggest you to send over a sample project showing the issue.
