datagrid sort and select row

Hello, I have 3 Columns that contain the following: Column1 - unique data Column2 - item description Column3 - total number of item for each row Sometimes Column2 can be emtpy. For e.g. if i have item=1, description="", totalcount="3" and row=10, if i click the column header2 for sorting, how will i be able to get the key value using find in the dataview? Below is my code that works only if column2 contains data. :( int index = -1; dataview.Sort = dataViewSource.Sort + ", " + column1; object[] myobject = new object[] { datarow.column2, datarow.column1 }; index = dataview.Find( myobject ); Please help. thanks, mutant
