Strange behaviour on column width / row height changes

Hi,

When I resize the column widths of my gridgroupingcontrol - if I resize so that the width is 0 or negative, the column simply disappears and i cannot bring it back. I have tried to catch the event TableModel.ColWidthsChanging to avoid widths of 0 or negative, but in this particular scenario, the event is not thrown. It is thrown for widths greater than 0.

The same applies for row heights.

Please can you tell me how I can stop resizing of column widths or row heights to 0.

Thanks.

Hi Mitul,

You need to catch the gridGroupingControl.TableControlResizingColumns event to avoid the columns getting hidden completely when resizing. Below is the code snippet.

void gridGroupingControl1_TableControlResizingColumns(object sender, GridTableControlResizingColumnsEventArgs e)
{
    if (e.Inner.Reason == GridResizeCellsReason.MouseUp && e.Inner.Width == 0)
        e.Inner.Cancel = true;
}

Similiarly, for rows you could catch the grid.TableControlResizingRows event handler.

Have a nice time.

Hi Mitul,

The Resizing of a column can be prevented by handling the TableControlResizingColumns event and setting the e.Inner.Cancel to true. Also the resizing of a row can be prevented by handling the TableControlResizingRows event and setting the e.Inner.Cancel to true.

private void gridGroupingControl1_TableControlResizingColumns(object sender, GridTableControlResizingColumnsEventArgs e)
{
e.Inner.Cancel = true;
}
