Hi, I am binding my RadGridView to an ObservableCollection<>. However, I do not want all columns to show up in my Grid View. Is there a way to hide it in XAML or as some annotation in the class definition?

I could make the undesired fields private and it disappears, but there are some times when I use the another ObservableCollection of the same object where I want all the columns
thanks

Hello Bhavik,

You may try to set the IsVisible property of the column to "False".

Thanks that worked!

I am hiding the column from the view model at start. Based on some drop down changes, i want to show the column.
But I when I associate this property using two way binding property, its not getting updated to unhide the column.

Could you share a bit more details about your implementation? Generally, any relevant information and code-snippet would be helpful.

Thanks Maya for your reply.

Here's my sample code

<telerik:GridViewDataColumn Width="150"  DataMemberBinding="{Binding Status}" IsVisible= "{Binding Source={StaticResource MyViewModel}, Path=IsAdminUser}">

   <telerik:GridViewDataColumn.Header>

      <TextBlock Text="Status"/>

   </telerik:GridViewDataColumn.Header>

</telerik:GridViewDataColumn>

View Model: MyViewModel

 

 public bool IsAdminUser
 {
    get { return isAdminUser; }
    set 
    {
       isAdminUser = value;
       RaisePropertyChanged(() => this.IsAdminUser);
    }
 }
