How to implement GroupByExpressions

[Sandeep Pulkundwar]

Hi,
I want to implement GroupByExpressions  in RadGridView  but my requrement is
different I want Header with two GroupByExpressions .
I have used
GridGroupByExpression expression1 = new GridGroupByExpression(grdSearchResults.Columns[4]);
grdSearchResults.MasterGridViewTemplate.GroupByExpressions.Add(expression1);
GridGroupByExpression expression = new GridGroupByExpression();
expression.Expression = "TimeZone as TimeZone format \"{0}: {1}\" Group By TimeZone";                    
grdSearchResults.MasterGridViewTemplate.GroupByExpressions.Add(expression);
 but this is giving two trees for GroupByExpression. I want single GroupByExpressions  /Single Header but with two expression
Example:
Property Name:United Kingdom(TimeZone:Estern Standerd Time)

Can you please give me some suggessions please

Thanks

Hi Sandeep Pulkundwar,

In the new version of RadGridView control this is supported functionality. You can use the following code snippet to apply grouping based on two conditions:

GroupDescriptor groupDescriptor = new GroupDescriptor();
groupDescriptor.GroupNames.Add(grdSearchResults.Columns[4].Name, ListSortDirection.Ascending);
groupDescriptor.GroupNames.Add("TimeZone", ListSortDirection.Ascending);
this.radGridView1.GroupDescriptors.Add(groupDescriptor);

Also, you can use the advanced expression mode:

this.radGridView1.GroupDescriptors.Expression = string.Format("{0}, TimeZone", grdSearchResults.Columns[4].Name);

I hope this helps.
