programmatically calling the button click event in a cell of type pushbutton

[Ted Osberg]

How can I programmatically fire the Button click event on a cell that has a celltype of pushbutton? Not only would the event fire when the user clicks on the button, but I would also like the event to fire when the user presses the Enter/Return key while in the cell. Thanks!

Here is one way you can do it by faking a click on the cell.

//click cell 4,4
this.gridControl1.Focus();
Point pt = this.gridControl1.ViewLayout.RowColToPoint(4, 4, true, GridCellSizeKind.ActualSize);
pt.Offset(3,3); //move it a little
Syncfusion.Drawing.ActiveXSnapshot.FakeLeftMouseClick(this.gridControl1, pt);

Actually, I made a mistake. The celltype is actually EllipsesText (from your example) and only takes up the last 20 pixels of the column width. I tried your example and it doesn''t work, even when I offset the point n pixels. I get a round circle with line thru it whenever I hit the enter or return key. Any suggestions on this one? Thanks!

Is there a way for me to get a handle to the EllipseText button itself?

I think you would have to expose methods to do this. It will take touching a couple of classes I think.

//A) in the EllipsisCellRenderer  class
//1) add a button member and assign it in teh constructor

private EllipsisCellButton button;
public EllipsisCellRenderer(GridControlBase grid, GridTextBoxCellModel cellModel)
	: base(grid, cellModel)
{
	this.button = new EllipsisCellButton(this);
	AddButton(this.button);
}

//2) add this public method method
public void PerformClick()
{
	this.button.PerformClick(new GridCellEventArgs(this.RowIndex, this.ColIndex));
}

//B) in the EllipsisCellButton class, add this method
public void PerformClick(GridCellEventArgs e)
{
	base.OnClicked(e);
}


//C) here is the code that clicks it

this.gridControl1.Focus();
EllipsisCellRenderer cr = this.gridControl1.CurrentCell.Renderer as EllipsisCellRenderer;
if(cr != null)
	cr.PerformClick();
