Hello,
I have an UltraWinGrid with a hierarchical DataSet consisting of 3 DataTables and Relations between them. Everything concerning the Bands works fine except that the [+] Expanders are also shown in front of rows, which don't have any sub-data linked. When you click on it, it disappears. Is there any way to get around this?
I am currently using Infragistics 7.2
Greetings, nils
Thanks for the quick answers, it works perfectly. And thanks Mike for reminding me to test the whole thing :)
Just so you know, the ExpansionIndicator property defaults to CheckOnExpand for a reason. DataSets can be slow when retrieving child rows. If you set this property to CheckOnDisplay, then the grid will check for the existance of child rows when the row is painted on the screen. This can adversely affect the performance of your application.
Nils,
Change the DisplayLayout.Override.ExpansionIndicator to CheckOnDisplay. This can also be set on the individual Band's Override object.
