I found this discussion, but can''t figure it out...any sample apps?

Hi Eric,

You can handle the QueryCellStyleInfo event to set the Style property of the summary cell to make as a editable cell. See the below code snippet for more details.

if(e.TableCellIdentity.TableCellType==GridTableCellType.SummaryEmptyCell || e.TableCellIdentity.TableCellType==GridTableCellType.SummaryFieldCell)
{

e.Style.CellType = "TextBox";
e.Style.BackColor = Color.White

//By default Enable property of summary to False.
//you need to change the Enabled property to True.
e.Style.Enabled = true;

//By default ReadOnly property of summary to True.
//you need to change the ReadOnly property to False.
e.Style.ReadOnly = false;

}

Update the summary using HashTable : http://www.syncfusion.com/Support/user/uploads/GGCSummary_420bb09d.zip

Update the summary using Last record : http://www.syncfusion.com/Support/user/uploads/LastrecUpdateSummaryNavigate_9b080d29.zip

I have already done all that you have mention.. As I said I am able edit summary cell unless i click on any record cell...but when i click on the record cell after that i can not edit summary cell it throws me to the record cell earlier selected

Hi Harshad,

Try setting the CurrentRecord to null for summary cell in the TableControlCurrentCellStartEditing event of the grid. See if this helps

private void gridGroupingControl1_TableControlCurrentCellStartEditing(object sender, GridTableControlCancelEventArgs e)
{
GridCurrentCell cc = e.TableControl.CurrentCell;
GridTableCellStyleInfo style = cc.Renderer.CurrentStyle as GridTableCellStyleInfo;
Element el = style.TableCellIdentity.DisplayElement;

if( el.Kind == DisplayElementKind.Summary )
{
e.TableControl.Table.CurrentRecord = null;
}
}

Please refer to the attached sample for implementation.

I'd like to gain access to the sample above, as I'm facing the same issue.

Thank you.
