How to Allocate Equal Column Size in WinForms GridGroupingControl

18 Nov 20181 minute to read

The parent and child table columns’ width can be set equally in proportion to the grid control’s client width by dynamically setting the columns width in TableModel.QueryColWidth event handler. When it deals with a nested table, QueryColWidth event of the entire nested table must be handled to set the respective nested table columns width. In QueryColWidth event handler, the available width for the columns can be calculated as follows,

availableArea = groupingGrid.ClientSize.Width - gridModel.ColWidths.GetTotal(0, girdModel.Cols.HeaderCount) - indentColsTotalWidth;

and the proportional columns width can be calculated as follows,

C#

Size = (int) availableArea / (grid.TableDescriptor.VisibleColumns.Count);
