[Solved] GridView DistinctFilter not applied after reset of itemsource!

[Johannes]

Hi,

I'm filtering two columns, with distinct filters. everything works as expected, as long as I do not update the ItemSource.
When I do reset the ItemSource (does not matter, if I reset to a completely different object, or clear/add the existing ObservableCollection), the Filter isn't applied.

How can I force to reevalute the filters? (or any other way to fix this issue)

Thanks
Johannes

Hi Johannes,

 When you reset items source everything goes away . You may not even have the same columns with the new source.

Thank you.
Got it working.

after reseting the itemsource, I create a new ColumnFilterDescription, and add all DistinctValues from the old ones:

 

 

ColumnFilterDescriptor tmp = _radGridLagerbestandArtikelFilter;

 

_radGridLagerbestandArtikelFilter =

new ColumnFilterDescriptor((IDataFieldDescriptor)this.radGridLagerbestand.Columns["ARTIKEL"]);

 

 

foreach (var dv in tmp.DistinctFilter.DistinctValues)

 

{

_radGridLagerbestandArtikelFilter.DistinctFilter.DistinctValues.Add(dv);

}

 

this.radGridLagerbestand.FilterDescriptors.Add(_radGridLagerbestandArtikelFilter);

 

....
