I am filtering my gridview using dataview. I am passing the filter command to dataview as mentioned below;

C#

string strFilter= " 0=0 ";  
  
if (Session["SampleSession"] != null)     
{       
  strFilter= strFilter+ " and EmpName = '" + Session["SampleSession"].ToString() + "'";     
} 
  
dv.RowFilter = strFilter;  // Throws an error here!

It throws an error of Missing operand after 'Operator Name' operator in above line.

I believe there is small error which i am unable to catch.

Please guide me!

Are you sure EmpName does not contain spaces? It seems to me its because a field name has a space on it and you might want to wrap that with [] to make it work.

May be you need to check first bit of your string which is
string strFilter= " 0=0 "; Not Sure what would you mean by "0=0" ? Please put bit more information :)

Where 'Operator Name' comes from? Debug your code well. You are appending to strFilter. What is the value of strFilter before and after that statement. If you cannot get the problem, post those values here.

Try using the @ directive in the strFilter clause.

string strFilter= @" 0=0 "; 
if (Session["SampleSession"] != null)     
{       
  strFilter= strFilter+ @" and EmpName = '" + Session["SampleSession"].ToString() + "' ";     
}
