The code below results in 'contains "high" and contains "high"' instead of 'contains "high" and contains "prod"'.  I can't figure out what I'm doing wrong.  Can anyone help?

filterExpression 

 

filter = new FilterExpression();

 

 

filter.Predicates.Add(

FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, GridFilterCellElement.ParameterName);

 

 

filter.Parameters.Add(

GridFilterCellElement.ParameterName, "high");

 

 

filter.Predicates.Add(

FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, GridFilterCellElement.ParameterName);

 

 

filter.Parameters.Add(

GridFilterCellElement.ParameterName, "prod");

 

 

 

this.radGridView.Columns["Description"].Filter = filter;

Hi Charles,

You should add the second parameter as a ParameterName2 in this case. Here is the modified code:

FilterExpression filter = new FilterExpression(); 
 
filter.Predicates.Add(FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, GridFilterCellElement.ParameterName); 
filter.Parameters.Add(GridFilterCellElement.ParameterName, "high"); 
 
filter.Predicates.Add(FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, GridFilterCellElement.ParameterName2); 
filter.Parameters.Add(GridFilterCellElement.ParameterName2, "prod"); 
 
this.radGridView1.Columns["Name"].Filter = filter;  
 

If you need further assistance, please write me back.

Best wishes,
