Column Freezing

[Tannearu Hazarathaiah Gupta]

HI,

If a column that is currently 'frozen' is dragged to the right of a column is not frozen. Then the column that is being dragged will no longer be frozen. If a column that is currently not frozen is dragged to the left of a column that is frozen, then that column should be frozen.

Please resolve the problem ASAP.

Hi Tannearu,

You can handle the QueryAllowDragColumnHeader event and change the frozen column count. Here is a code snippet to show this.

private void gridDataBoundGrid1_QueryAllowDragColumnHeader(object sender, GridQueryDragColumnHeaderEventArgs e)
{
if( e.Reason == GridQueryDragColumnHeaderReason.MouseUp)
{
int fColCount = e.Grid.Model.Cols.FrozenCount;
if( !(e.Column <= fColCount && e.InsertBeforeColumn <= fColCount ) )
{
e.Grid.Model.Cols.FrozenCount = e.InsertBeforeColumn;
}
}
}
