vb.net - How to create group alpabet gridview devexpress? -


can 1 me create group alphabet gridview picture? i've tried code, rows not grouped alphabet.

private sub gridview1_customcolumndisplaytext(sender object, e customcolumndisplaytexteventargs) handles gridview1.customcolumndisplaytext     if e.column.fieldname = "companyname" andalso e.isforgrouprow         dim rowvalue string = gridview1.getgrouprowvalue(e.grouprowhandle, e.column)          dim val string = microsoft.visualbasic.left(rowvalue, 1)          e.displaytext = val     end if end sub

group alpabet gridview devexpress

there no need handle customcolumndisplay text event handler extract first letter of "companyname" value. instead, set gridcolumn.groupinterval property "companyname" gridcolumn "alphabetical". instance:

mygridview.columns("companyname").groupinterval = columngroupinterval.alphabetical
