Column Freezing

[Tannearu Hazarathaiah Gupta]

Hi,

We are using gridgroupping control. i want achive column freezing following condition.


If a column that is currently ‘frozen’ is dragged to the right of a columns 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 become frozen.


Please resolve the problem asap.

Hi Tannearu,

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

private void TableControl_QueryAllowDragColumn(object sender, GridQueryAllowDragColumnEventArgs e)
{
if( e.Reason.ToString() == "MouseUp")
{
int fColCount = e.TableControl.Model.Cols.FrozenCount;
int row,col;
e.TableControl.TableDescriptor.ColumnToRowColIndex(e.Column,out row,out col);
int irow,icol;
e.TableControl.TableDescriptor.ColumnToRowColIndex(e.InsertBeforeColumn,out irow,out icol);
if( !(col <= fColCount && icol <= fColCount ) )
{
e.TableControl.Model.Cols.FrozenCount = icol;
}
}
}

Here is a sample.
