Column ResizeToFit ComboBox Question

[Kyle DeVoe]

I have a question about using the column ResizeToFit() function. If if have a combobox in my column, the column will resize to the longest string in my combobox choicelist, even if that string isn't the selected item. How do I get the grid to ignore the choice list and only resize the column based on the display text in the combobox?

thanks,
Kyle

Hi Kyle,

This can be acheived by deriving the GridComboBoxCellModel class and overriding OnQueryPrefferedClientSize Method to change the default resizing behavior of the combo box cell in a grid. Here is a code snippet to show this.

public class MyComboBoxCellModel : GridComboBoxCellModel
{
public MyComboBoxCellModel(GridModel grid): base(grid){}

protected override Size OnQueryPrefferedClientSize(Graphics g, int rowIndex, int colIndex, GridStyleInfo style, GridQueryBounds queryBounds)
{
Size size = g.MeasureString(style.FormattedText,style.GdipFont).ToSize();
return size + this.ButtonBarSize;
}
public override GridCellRendererBase CreateRenderer(GridControlBase control)
{
return new MyComboBoxCellRenderer(control, this);
}
}

Here is a sample.
