GGC sort header

[Administrator]

When you drag a column name to the "drag a column here to sort by that column" area a header is created for each set of grouped items that is the value in the name of the column.

I want to be able to set this text to a description when the user sorts by a certain column.

I know I can use the GGC_QueryCellStyleInfo event to set this text but I need to set this header text when I am populating the data not when the user drags this column. Is there a way to set this before the user does a sort?

Hi Rich, The Group CaptionText can be customized using the TableDescriptor.ChildGroupOptions.CaptionText property (gridGroupingGrid.TableDescriptor.ChildGroupOptions.CaptionText = "{CategoryName}: {Category}";). But this customizes the text for all the groups. I am not sure how you can set the caption text for a particular group (by a column) before it was grouped. If you can explain the scenario and why the QueryCellStyleInfo event is not elegant then we can suggest a better way. Also please refer to the below forum thread to see if that helps. http://www.syncfusion.com/Support/forums/message.aspx?MessageID=43171 Regards, Calvin.

Hi Calvin,

Thanks for the quick reply.

I have one column "Type" and when the user sorts by that column I want to add to the header a description for that "Type". There are many rows that will belong to the same "Type" and I don''t want to add an extra column to contain the desription for a type since it will be all the same description.

I have the description for each "Type" when I am creating each row in the grid and wondered if there was some way to set this up at that point. I guess I can always save the description and use it when the GGC_QueryCellStyleInfo is fired. Just wondering if there was some other way to do this?

Hi Rich,

I believe handling the QueryCellInfo event will be the only best way for the mentioned scenario. The description can be stored in a hash table with the “Type” column value as the Key and it can be retrieved in the QueryCellInfo handler.
