Hi everyone,

I really hope someone can help with this tricky issue. I have a gridview with a filterdescriptor to filter out any inactive contacts for a customer;

<telerik:RadGridView  ItemsSource="{Binding Customers_Contacts, Mode=OneWay}"...
                        <telerik:RadGridView.FilterDescriptors>
                            <telerik:FilterDescriptor Member="SafeInActive" IsCaseSensitive="True" Operator="IsEqualTo" Value="False" />
                        </telerik:RadGridView.FilterDescriptors>

This all seems to work fine when a change the datacontext to the customer, the list then filters the Customers_Contacts related entity list for the customer only showing active customers..

The problem I am having is whehn I set one of the contacts in the list to be inactive it is not filtered out of the list??

Any ideas?

Thanks

Mark

Hello,

 As I understand you edit a single value in code behind and the filter is not applied.

If this is the case, then you should inform the GridView that the collection has changed. You may do this like so: 

myGridView.Items.EditItem(editedItem);
// change the value
 myGridView.Items.CommitEdit();

Please let me know how it works.

I have the following code and still the grid isn't filtering.  Am I missing something ?


private void AddFilterDescriptor(string Member, FilterOperator Operator, object Value)
{
    rgvExpenses.FilterDescriptors.Clear();
    FilterDescriptor filter = new FilterDescriptor();
    filter.Member = Member;
    filter.Operator = Operator;
    filter.Value = Value;
    rgvExpenses.FilterDescriptors.Add(filter);
    rgvExpenses.Items.CommitEdit();
}

Hi,

Would you please ensure there is a valid Member to filter on? Do you have all the records still presented after you executed the shared code?

As an additional note, you do not need to commit the edit unless you are already editing.

It's all right it works.  I was just not filtering enough columns to see the change.  Thank you
