Hi,

I am using GGC with nested tables.

Hi Prathima

You can use the following code to expand and collapse the nested table records.

To Expand
this.gridGroupingControl1.Table.ExpandAllRecords();

To Collapse
this.gridGroupingControl1.Table.CollapseAllRecords();

To Expand a selected record
this.gridGroupingControl1.Table.SelectedRecords[0].Record.IsExpanded = true;

Thanks for the reply.It works fine.

I have one more problem, If my grid has only grouping and no nested table..then also on click of this button it expands all the groups.
So I want to make a check if the grid has nested table then only it should expand all records.How can I do this check..?

I tried with HasChildren property..it is returning true even though the grid doesn''t have any nested table.

Thanks,

Hi Prathima ,

I think that you have grouped the main table and the main table has got nested table.

The following code checks if the each record in each group has got records of nested table.

If so it expands the group as well as the nested table records for each group.

foreach(Group g in this.gridGroupingControl1.Table.TopLevelGroup.Groups)
foreach(Record r in g.Records)
if( r.NestedTables[0].ChildTable.Records.Count > 0)
   g.IsExpanded = true;
   r.IsExpanded = true;
}
