ggc - fixed columns

Hi,

Is it possible to keep a specific column (the left-most column) from scrolling horizontally and cause it to be drawn on top of overlapping columns ?


Thanks in advance.

Hi Ryan,

You can achieve this by setting the TableDescriptor.FrozenColumn property to the name of the first column.
Here is the code snippet.

this.gridGroupingControl1.TableDescriptor.FrozenColumn = "ColumnName";

Thanks, that's exactly the behavior I need :)

Now all I need is to prevent the frozen column from being resized.
Is it possible to identify the name of the column to be resized from within TableControlResizingColumns, or is there a similar settings (like: ".FrozenColumn =") that does the job ?

Hi Ryan,

You can use this code to get column name in a TableControlResizingColumns event.

private void gridGroupingControl1_TableControlResizingColumns(object sender, GridTableControlResizingColumnsEventArgs e)
{
int iColIndex = e.Inner.Columns.Left;
int iField = e.TableControl.TableDescriptor.ColIndexToField(iColIndex);
if( iField >= 0 )
Console.WriteLine( e.TableControl.TableDescriptor.Columns[iField].Name);
}

The above code does not seem to work, its returning different columns than the one selected in my grid. We're using a combination of Bound Fields, and 2 Unbound action fields in a hierarchy(2 GridTables).

There is a bug in the code you guys provided, if parent and children table have different column counts, you need to do a check for the index being valid as this event is still fired for columns which are not there. There is a few versions of this code on your forums, I suggest you update all of the threads with the right code...

if ( e.Inner.Columns.IsCols)
{
int colIndex = e.TableControl.TableDescriptor.ColIndexToField(e.Inner.Columns.Left);

if(colIndex < e.TableControl.TableDescriptor.VisibleColumns.Count && e.TableControl.TableDescriptor.VisibleColumns[colIndex].Name == "Whatever" )
e.Inner.Cancel = true;
}

Hi James,

Thank you for your suggestion.
