Derived cell control - auto expand the column width to fit control

[Colin Bolton]

I have a custom cell type(implementing a GridGenericControlCellModel as in the calendar example) which contains a control whose size may change dynamically. Is there a simple way to automatically expand the width of the column to fit the size of the control if it is too small?

Also if the user changes the column width I want to restrict the width to the size of the largest control in the column, is there a simple way (property to set?) or do I have to handle the column resizing events manually??

Cheers,

Colin

Hi Colin,

Regarding the Question 1:

To resize the width of the column to fit the size of the control , you need to call the ResizeToFit method . Here is a code snippet.

gridControl1.RowHeights.ResizeToFit(GridRangeInfo.Cell(2, 4));
gridControl1.ColWidths.ResizeToFit(GridRangeInfo.Cell(2, 4));

Note : this method only applicable for usercontrol celltype. If the celltype is control cell type , you need to caluclate the width of the control and assign the colWidth explictly.

Regardig the Question 2:

You need to handle the ResizingColumns event for preventing the resizing of the column in a grid. Here is a code snippet.

private void gridControl1_ResizingColumns(object sender, GridResizingColumnsEventArgs e)
{
if(e.Columns.Left == 2)
e.Cancel = true;
}

Let me know if this helps.
