    Hi,

    This issue is related to filtering the content in data grid control.

    We are using DataGridCollectionView in our code and our data set is large it contains approximately 15000 rows.

    Following are the properties set on DGCV :
    dataGridCollectionView.AutoFilterMode = AutoFilterMode.And;
    dataGridCollectionView.DistinctValuesConstraint = DistinctValuesConstraint.Filtered;

    When we are using custom filtering for some of the columns QueryDistinctValue is getting fired for each row.
    In our case it is getting fired around 15k times and it is degrading the performance of application significantly.
    Because of this it is taking around 1 min delay to only show the editor of particular cell.

    Is there any way possible to restrict the QueryDistinctValue event from getting fired for all the rows.
    Any inputs on this area will be helpful for us.

    Current Xceed version we are using is : 3.8.11322.13150.
