Hi,
I am using this property for best fit my column(objComboBox.MultiColumnComboBoxElement.AutoSizeDropDownToBestFit =
true;) in RadMultiColumnComboBox columns but when i have data source which have a lot of data i need to implement filtering on it.
I am implemening it in this way:
FilterDescriptor filter = new FilterDescriptor();
filter.PropertyName = objComboBox.DisplayMember;
filter.Operator =
FilterOperator.Contains;
objComboBox.EditorControl.MasterTemplate.FilterDescriptors.Add(filter);
but it's take a lot of time when the filter is auto complete.
Please how to make filtering in this controll and dont take a time.
Note: When i am not using AutoSizeDropDownToBestFit it's( Filter) works fine and i dont have delay( my data source have more then 1000 items and 3 columns), but when i have Combo which have more then 3 column and the size of DropDown is less, than the user can not see what have in that control.
What is your suggestion to eliminate this issue.
Best regards,
Gezim
