Expand Groups

[Driss Selhoum]

Hi,
I have a GridGrouping Control Bound to a DataSet which contains a Datarelation. I cannot get the Parent table to be expanded even when I Click on the Plus Button.

Hi Driss

Have you taken a look at the Hierarchies\HierarchySample that ships with Essential Grid which shows how you can display Hierarchical Data in the Grid.

Yes I have, But my problem is I have a DataRelation object inside a DataSet that describes a ParentChild relationship. And I give the DataSet as the DataSource of the GridGroupingControl and when I try to expand the Parent table rows nothing happens.

I assume that I have to describe the relationship using the GridGrouping Properties so that it can display the Data correctly.

Thank you for your help

Hi Essential Grid can display any ADO.NET dataset without further configuration. Set up the dataset with its relations and initialize the grid with the dataset. The grid will automatically extract all column and relation information from the dataset and display its records and relations. I have attached a modified version of the HierarachySample that I was referring to in the earlier post. I took the existing sample and deleted the GridGroupingControl from the form and added a CreateGrid() method that programatically adds the Grid to the WebForm and sets it''s DataSource property. Since you are adding the Grid programatically ensure that you have the proper references to all the required assembllies as noted in the Using GridGroupingControl section of the Users Guide.
