Summery Row columns dont stretch to needed width

[Klaus Aman]

how to make summery row columns stretch entire column??

is there a decimalaggregate too ?

Hi Klaus Aman,

There is not direct support to change the width based on the text in the Table summary. We are preparing the workaround to provide column width based on the table summary value. We need some to achieve this, and we will update you further details on or before August 27, 2024.

We appreciate your patience until then.

We are almost in the final stage of preparing the workaround to provide column width based on the table summary value. We need some to achieve this, and we will update you further details on or before August 29, 2024.

Hi Klaus Aman, 

Thank you for your patience.

We don't have direct support for sizing the column based on the TableSummary text. However, you can achieve this by overriding the GridColumnSizer class and calculating the size of the Summary text using the FormattedText. You can then return the modified size for the respective columns inside the CalculateHeaderWidth method. Please find the code snippet below.

Code snippet:

 protected override double CalculateHeaderWidth(GridColumn column, bool setWidth = true)

 {

     for (int i = this.DataGrid.RowGenerator.Items.Count - 1; i >= 0; i--)

     {

         if (this.DataGrid.RowGenerator.Items[i] is SpannedDataRow)

         {

             var spannedRow = this.DataGrid.RowGenerator.Items[i] as SpannedDataRow;

             foreach (var visibleColumn in spannedRow.VisibleColumns)

             {

                 if (visibleColumn.GridColumn.MappingName.Equals(column.MappingName))

                 {

                     var element = visibleColumn.ColumnElement as GridTableSummaryCell;

                     if (element.Content.ToString() != "")

                     {

                         Size SummaryTextSize = new Size(0, 0);

                         // The font size of the Text in the TableSummary is 14

                         SummaryTextSize = MeasureString(element.Content.ToString(), element.FontFamily, 14, element.FontStyle, element.FontWeight, element.FontStretch);

                         SummaryColumnSizes[visibleColumn.GridColumn.MappingName] = SummaryTextSize;

                     }

                     break;

                 }

             }

             break;

         }

     }

     double defaultWidth = base.CalculateHeaderWidth(column, setWidth);

     if (SummaryColumnSizes.ContainsKey(column.MappingName) && (defaultWidth < SummaryColumnSizes[column.MappingName].Width || SummaryColumnSizes[column.MappingName].Width != 0))

         return SummaryColumnSizes[column.MappingName].Width;

     else

         return defaultWidth;

 }
