Hi Ranjan,


Thank you for your interest in Syncfusion products.


We have created a simple sample with dynamic filter and ordinary filter in GridGroupingControl. The GridDynamicFilter class is used to wire a custom filter bar to the Grid Grouping control by replacing the default filter bar. Please refer the attached sample.

the NullReferenceEception happens, if there are cells with empty text.

I changed line 38 of Form1.cs of your example to

dr[j] = (i == 3) ? "" : string.Format("row{0} col{1}", i, j);

Now when pressing the filter symbol does nothing. Clicking in the text area of the filter cell raises the exeption.
