Hi Gregory,
Thanks for using Syncfusion product.
To add the summary while click on the column, you could use the GridTableCellStyleInfo and SummaryRows in TableControlCellClick event. Please refer the following code example,

after clicking the next column, GridSummaryColumnDescripto did not disappear
so that the second, third |
To add the new column, you could create the GridsummaryColumnDescriptor for that column the add this summary column in SummaryRows collection. If want to remove the column from summary columns when click on the same column, you could check and remove that column from SummaryColumns collection. Please refer the following code example
Code example
private void GridGroupingControl1_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e)
{
GridTableCellStyleInfo style = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex);
if (style.CellValueType == typeof(int))
{
if (style.TableCellIdentity != null && style.TableCellIdentity.Column != null)
{
string columnName = style.TableCellIdentity.Column.Name;
GridSummaryColumnDescriptor scd = null;
if (this.gridGroupingControl1.TableDescriptor.SummaryRows.Count == 0)
{
scd = AddSummaryColumn(columnName);
GridSummaryRowDescriptor srd = new GridSummaryRowDescriptor();
this.gridGroupingControl1.TableDescriptor.SummaryRows.Add(srd);
}
GridSummaryRowDescriptor summaryRow = this.gridGroupingControl1.TableDescriptor.SummaryRows[0];
var summarycolDescriptor = summaryRow.SummaryColumns.Cast<GridSummaryColumnDescriptor>().Where(x => x.DataMember == columnName);
if (summarycolDescriptor.Count() > 0)
{
var value = summarycolDescriptor.ToList()[0];
summaryRow.SummaryColumns.Remove(value);
}
else
{
scd = AddSummaryColumn(columnName);
summaryRow.SummaryColumns.Add(scd);
}
//To update the summary.
this.gridGroupingControl1.TableDescriptor.EnsureSummaryDescriptors();
}
}

when we click the second time in the same column - it should disappear only in what we clicked a second time
