Parent grid with multiple child grids

[Administrator]

Hi,

I am using a GridHierDataBoundGrid. I have two child grids that need to drop down from this grid. How can I specify this in code? Right now I am only able to see one dropdown arrow for one of the children grids - I need to see a dropdown for both.

Thanks!

You can show 2 buttons in the cell where you now have one. You can do it by:

1) adding code in the renderer''s Constructor to add another button.

public DropDownGridCellRenderer(GridControlBase grid, GridCellModelBase cellModel)
		: base(grid, cellModel)
{
	this.DisableTextBox = true;
	DropDownButton = new GridCellComboBoxButton(this);
	this.AddButton(new GridCellComboBoxButton(this));
	this.dbgrid = null;
}

2) set the button bar size in the model''s constructor.

public DBDropDownGridCellModel(GridModel grid)
	: base(grid)
{
	ButtonBarSize = new Size(2 * 20, 20);
}

3) Add a OnButtonClicked override to catch the click on either button. A this point, you would have to decide which child grid you want to see, and implement some way to show it.

protected override void OnButtonClicked(int rowIndex, int colIndex, int button)
{
	MessageBox.Show(button.ToString() + " clicked");
	//base.OnButtonClicked (rowIndex, colIndex, button);
}
