Determining Cell Image click?

[Kai Iske]

Is there a way to determine that the user has clicked on a cell's image?

Also, a nice thing to have would be to be able to supply some positioning information for the image as with the standard MS Label control, maybe.

Hi Kay,

thanks for the suggestion. We'll add such a property.

We'll also add a ImageClicked event to make it easier to detect a click on the image.

Here is what you can do now:

[C#]

protected override void OnCellClick(GridCellClickEventArgs e)
{
GridControlBase grid = this;

Point pt = new Point(e.MouseEventArgs.X, e.MouseEventArgs.Y);
GridStyleInfo style = grid.Model[e.RowIndex, e.ColIndex];
GridCellRendererBase renderer = grid.CellRenderers[style.CellType];
GridCellLayout layout = renderer.GetCellLayout(e.RowIndex, e.ColIndex, style);

bool clickedOnImage = (!layout.TextRectangle.Contains(pt) && layout.ClientRectangle.Contains(pt));

if (clickedOnImage)
{
MessageBox.Show(" Clicked on bitmap ");
}
else
base.OnCellClick(e);

}

[VB]

protected override void OnCellClick(GridCellClickEventArgs e)
{
Dim grid As GridControlBase = Me

Dim pt As Point = New Point(e.MouseEventArgs.X,e.MouseEventArgs.Y)
Dim style As GridStyleInfo = grid.Model(e.RowIndex,e.ColIndex)
Dim renderer As GridCellRendererBase = grid.CellRenderers(style.CellType)
Dim layout As GridCellLayout = renderer.GetCellLayout(e.RowIndex,e.ColIndex,style)

Dim s As String = ""

Dim clickedOnImage As Boolean = (Not lay.TextRectangle.Contains(pt) And lay.ClientRectangle.Contains(pt))

if (clickedOnImage)
{
MessageBox.Show(" Clicked on bitmap ")
}
else
MyBase.OnCellClick(e)

}

Thanks Stefan, that solves it for now.
