GridGroupingControl - Sort Arrow Change

[Badri Rajani Kanth]

Hi,

We are using V 4.2.0.37

When we simple/group sort any columns, currently arrow is displayed in column name. i just want to reverse the arrow. Say, I want ASC ->Down Arrow, DESC -> UP Arrow.

How can I do this?

Thanks & Rgds

Hi Rajani,

To change the sort direction in a column header, You need to handle the TableControlDrawCell and draw the sort triangle direction using the GridPaintTriangle.Paint() method.And also you need to turn off the default sort icon drawing by changing the ColumnHeader.Celltype to "Header". Please refer to the following code snippet demonstrates the technique to change sort direction.

this.gridGroupingControl1.TableDescriptor.Appearance.ColumnHeaderCell.CellType = "Header";

void gridGroupingControl1_TableControlDrawCell(object sender, GridTableControlDrawCellEventArgs e)
{
GridTableCellStyleInfo style = e.Inner.Style as GridTableCellStyleInfo;
if (style.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell)
{
e.Inner.Cancel = true;
e.Inner.Renderer.Draw(e.Inner.Graphics, e.Inner.Bounds, e.Inner.RowIndex, e.Inner.ColIndex, e.Inner.Style);
if (style.Tag != null)
{
ListSortDirection listSortDirection = (ListSortDirection)e.Inner.Style.Tag;
Rectangle rect = new Rectangle(e.Inner.Bounds.X + e.Inner.Bounds.Width / 3, e.Inner.Bounds.Y, e.Inner.Bounds.Width, e.Inner.Bounds.Height);// e.Bounds;
int i2 = Math.Max(0, (rect.Height - 4) / 2);
rect.Inflate(-i2, -i2);

Pen pen1 = new Pen(SystemColors.WindowFrame);
GridTriangleDirection triangleDirection = listSortDirection == ListSortDirection.Ascending ? GridTriangleDirection.Down : GridTriangleDirection.Up;
GridPaintTriangle.Paint(e.Inner.Graphics, rect, triangleDirection, Brushes.Black, pen1, true);
pen1.Dispose();
}
}
}

Hi Haneef,

Now I see two arrows, as old arrow is not yet removed.

These are my grid settings. Can you plz see if some thing is wrong?

Hi Rajani,

You can turn off the default sort direction drawing by using the ColumnHeaderCell.CellType property in a bottom of the form's load event. Below is a code snippet

[c#]
Bottom line of the form's load event
gridGroupingControl1.TableDescriptor.Appearance.ColumnHeaderCell.CellType = "Header";

Best Regards,
Haneef
