ExpandButton with different offsets for differet rows - does not work

[Administrator]

Hello! I use grid of ver 1.6.1.8 I want my cell button, that I use instead of GridDataBoundRowExpandCellButton in GridDataBoundGrid, to have offset from the left of edge of column equal to N*(Level of hierarchy): I mean - I have DataSource with two levels, and expand buttons for level 2 must be situated not under expand button for level 1, but to be offseted to the right side. This helps to display tree-like organisation of levels in DataSource. Now Problem: I store offset for current cell in GridStyleInfo.tag and in method OnLayout of descedant of the GridDataBoundRowExpandCellRenderer change bound for current button: /// protected override Rectangle OnLayout(int rowIndex, int colIndex, GridStyleInfo style, Rectangle innerBounds, Rectangle[] buttonsBounds) { int tag = 0; if(style.Tag != null) tag = (int)style.Tag; int offset = 10*tag; Rectangle rect = Rectangle.FromLTRB(innerBounds.Left + offset,innerBounds.Top, innerBounds.Left + offset + 15, innerBounds.Bottom); buttonsBounds[0] = GridUtil.CenterInRect(rect , new Size(11,11)); innerBounds.Location = new Point(innerBounds.Location.X + offset + 15, innerBounds.Location.Y); innerBounds.Width -= (offset + 15); return innerBounds; } And buttons are drawn at their correct places, but when I try to click on them - only buttons of level 1 works properly. For nested levels click on button does not work, but click at part of the cell, that situated under the button of level 1 - works: I mean that buttons are drown offsetted but they work like they all are situated without offset at the most left side of the cell. Can you suggest something? Thank you

I found solution:

In case if someone will need it too: in my ExpandButton that derives from GridDataBoundRowExpandCellButton
next methods were overrided:

public override int HitTest(int rowIndex, int colIndex, MouseEventArgs e, IMouseController controller)
{
GridStyleInfo style = this.Grid.GetViewStyleInfo(rowIndex, colIndex, true);
GridCellLayout layout = this.Owner.GetCellLayout(rowIndex, colIndex, style);

int tag = 0;
if(style.Tag != null)
tag = (int)style.Tag;
int offset = 10*tag;

Rectangle withButton = Rectangle.FromLTRB(layout.CellRectangle.Left + offset, layout.CellRectangle.Top, layout.CellRectangle.Left + offset + 11, layout.CellRectangle.Bottom);

if(withButton.Contains(e.X,e.Y))
{
return GridHitTestContext.CellButtonElement;
}
return GridHitTestContext.None;
}

public override void MouseDown(MouseEventArgs e, GridCellHitTestInfo ht)
{
GridStyleInfo style = this.Grid.GetViewStyleInfo(ht.RowIndex, ht.ColIndex, true);
GridCellLayout layout = this.Owner.GetCellLayout(ht.RowIndex, ht.ColIndex, style);

int tag = 0;
if(style.Tag != null)
tag = (int)style.Tag;
int offset = 10*tag;

Rectangle buttonBounds = Rectangle.FromLTRB(layout.CellRectangle.Left + offset, layout.CellRectangle.Top, layout.CellRectangle.Left + offset + 11, layout.CellRectangle.Bottom);
ht.CellButtonBounds = buttonBounds;

base.MouseDown (e, ht);
}

public override void MouseUp(MouseEventArgs e, GridCellHitTestInfo ht)
{
GridStyleInfo style = this.Grid.GetViewStyleInfo(ht.RowIndex, ht.ColIndex, true);
GridCellLayout layout = this.Owner.GetCellLayout(ht.RowIndex, ht.ColIndex, style);

int tag = 0;
if(style.Tag != null)
tag = (int)style.Tag;
int offset = 10*tag;

Rectangle buttonBounds = Rectangle.FromLTRB(layout.CellRectangle.Left + offset, layout.CellRectangle.Top, layout.CellRectangle.Left + offset + 11, layout.CellRectangle.Bottom);
ht.CellButtonBounds = buttonBounds;

if (FireClickOnMouseUp && buttonBounds.Contains(new Point(e.X, e.Y)))
OnClicked(new GridCellEventArgs(ht.RowIndex, ht.ColIndex));

this.SetMouseDown(ht, false);

}

Now it''s works - buttons have differet offset and they are working

Thanks anyway
