Set blank Description on Summary Row
posted

GroupByHhere is a screenshot when i drag a column to group by Trans Type.
Usually, when rows are grouped, the summary row will say something like "Trans Type : 3 items" or something like that.  
But i want to hide that default description because i have written my own ICustomSummaryCalculator for each row.

I tried to use this, but it still leave the empty area in blue summary row (see screenshot).   
     ultraGridSummary.DisplayLayout.Override.GroupByRowDescriptionMask = " ";

There description (empty areas above the summary cells in the blue summary row)

I tried to set GroupBySummaryDisplayStyle, it only provide option GroupBySummaryDisplayStyle.SummaryCells which show summary on the same level if it does not intersect with the summary row description. 

I also tried to use the InitializeGroupByRow event on the grid, and set the description to blank, but none works.  

Do you know of a way to get rid of that Description area so that it won't leave empty space?  Thanx

    I managed to solve it by adding a "blank" column: 

                UltraGridColumn blankColumn = _grid1.DisplayLayout.Bands[0].Columns[0];

     

                // BLANK COLUMN ENSURES THAT SUMMARY ONLY EVER OCCUPIES ONE LINE

                blankColumn.Header.VisiblePosition = 0;

     

                // In order to resize any column (in this case 'Blank') we need to temporarily

                // ensure it's visible before setting the width and restoring its visible property

                blankColumn.Hidden = false;

                blankColumn.Width = 0; // NOTE: it will set to the default minimum which appears to be 8

                blankColumn.Hidden = true;

     

                blankColumn.LockedWidth = true;

                blankColumn.AllowGroupBy = DefaultableBoolean.False;

                blankColumn.AllowRowFiltering = DefaultableBoolean.False;

                blankColumn.AllowRowSummaries = AllowRowSummaries.False;

                blankColumn.Header.Caption = string.Empty;
