In my grid there are about 110K rows, when i group some columns, to foreach all groupbyrow's rows will takes a long time. How can i select all rows( add all normal rows to slection collection) quickly?
Hi,
In 2011.2 a method SelectAll was added - http://help.infragistics.com/NetAdvantage/Silverlight/2011/1/CLR4.0/?page=xamGrid_Select_All_xamGrid_Rows_in_Groups_Bands_and_at_the_Root.html
Hope this helps
