Hi,
I have two checkboxs that, when checked, apply or remove custom filters. The filters work fine (mostly), only problem is that the first time FilterDescriptors.Clear(); is called all the rows in the grid dissapear. On any subsequent calls it works as expected.

Both checkboxes call the following method:

#region private void HandleCheckBoxFilters()

private void HandleCheckBoxFilters()

{

bool? PaidInFullChecked = CheckBox_PaidInFull.IsChecked;

bool? Show60PaymentsOnlyChecked = CheckBox_FixedAmount.IsChecked;

//RadGridView_TrusteeLedgers.FilterDescriptors.Clear();

CompositeFilterDescriptor compositeDescriptor = new CompositeFilterDescriptor();

compositeDescriptor.LogicalOperator = FilterCompositionLogicalOperator.And;

RadGridView_TrusteeLedgers.FilterDescriptors.Clear();

if (PaidInFullChecked == true)

{

FilterDescriptor filterDescriptor_PaidInFull = new FilterDescriptor();

filterDescriptor_PaidInFull.Member = "PaidInFull";

filterDescriptor_PaidInFull.Operator = FilterOperator.IsEqualTo;

filterDescriptor_PaidInFull.Value = true;

filterDescriptor_PaidInFull.IsCaseSensitive = false;

compositeDescriptor.FilterDescriptors.Add(filterDescriptor_PaidInFull);

}

if (Show60PaymentsOnlyChecked == true)

{

FilterDescriptor filterDescriptor_FixedAmount = new FilterDescriptor();

filterDescriptor_FixedAmount.Member = "TotalRemaining";

filterDescriptor_FixedAmount.Operator = FilterOperator.IsEqualTo;

filterDescriptor_FixedAmount.Value = Convert.ToDecimal(60);

filterDescriptor_FixedAmount.IsCaseSensitive = false;

compositeDescriptor.FilterDescriptors.Add(filterDescriptor_FixedAmount);

}

RadGridView_TrusteeLedgers.FilterDescriptors.Add(compositeDescriptor);

}

#endregion
