Highligting when draging & droping in gcc

[Administrator]

Hello

in the ggc, When draging and dropping i want to Highlight or change the backcolor of the current row (target) and the backcolor of the source row, i tried the following code but it''s not working

private void grid_DragOver(object sender, DragEventArgs e)
{

GridGroupingControl grid = sender as GridGroupingControl;
if(grid!= null)
{
GridTableControl tableControl = grid.TableControl;
Point pt = new Point(e.X, e.Y);
int row, col;
if(tableControl.PointToRowCol(pt, out row, out col))
{
GridTableCellStyleInfo style = tableControl.Model[row, col];

if(style.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell // .RecordRowHeaderCell
|| style.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
{
style.BackColor = Color.Yellow;
grid.TableDescriptor.Appearance.AnyHeaderCell.BackColor = Color.Yellow;

}

}

the other question taht i have is :

How can i reference the RecordFieldCell and the AlternateRecordFieldCell of the nestedTables

could you please help me with this.
Thanks

You cannot set individual cell properties in a GridGroupingControl using an indexer.

To set properties on a cell by cell basis, you need to use QueryCellStyleInfo. Here is a little sample.

Where do you want to reference records in a child table? Depending on where you are, there may be simpler ways. In general, you can try using this.gridGroupingControl1.GetTable("ChildTableName").Records to get at all records in a child table. There is also a FilteredRecords collection that gives you the visible records.

Thank you very much Clay, it''s works
for referencing the Childtable, i mean :

in the QueryCellStyleInfo when i want to modify the style of a RecordRowHeaderCell
i use the condition :

if(e.TableCellIdentity.TableCellType == GridTableCellType.RecordRowHeaderCell

but what i want to modify is the RecordRowHeaderCell style of the nestedChilds

Thanks

Try code like:

private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
	if((e.TableCellIdentity.TableCellType == GridTableCellType.RecordRowHeaderCell || 
		e.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordRowHeaderCell)
		&& (e.TableCellIdentity.Table.TableDescriptor.Name == "ChildTable"))
	{
		e.Style.BackColor = Color.Red;
	}
}

Thank you
always in the QueryStyleInfo
how can i test someting like
" if(e.TableCellIdentity.RowIndex == 5)"
but this time for the nested tables

I am not sure I understand what you want, but did you try adding the criteria to your rowindex condition?

e.TableCellIdentity.Table.TableDescriptor.Name == "ChildTable"))

Or, do you want to find the 5th row in the child table? If so, try adding a criteria like:

e.TableCellIdentity.Table.TableDescriptor.Name == "ChildTable" && e.TableCellIdentity.Table.Records.IndexOf(e.TableCellIdentity.DisplayElement.ParentRecord) == 5
