Fixed Columns not working as expected with multibands
posted

HI,

I have a grid of data with multiple bands, each band has the same columns.  I want to freeze the first column in each band so that when you scroll to the right you always have that column visible.

To do this I have this at the end of my InitialiseRow method:

      for (int i = 0; i < _positionsGrid.DisplayLayout.Bands.Count; i++)
      {
        _positionsGrid.DisplayLayout.Bands[i].UseRowLayout = false;
        _positionsGrid.DisplayLayout.Bands[i].Columns[0].Header.Fixed = true;
      }

But when the grid appears it only freezes the column at the lowest band, so when I scroll that column remains fixed but that the columns in the uppers band scroll.

Am I doing something wrong?

    You might want to consider moving the code to InitializeLayout as you only need to run it once and not every time a row is initialized.

    I'm guessing that you have hidden columns in the bands where no column is frozen. You could try accessing first visible column, e.g. something like this:

     

     

     

     

     

     

     

    Dim band As UltraGridBand
    Dim col As UltraGridColumn

    For Each band In e.Layout.Bands
      col = band.GetFirstVisibleCol(e.Layout.ColScrollRegions(0), False, False)
      col.Header.Fixed = True
    Next
