GridSummaryRowDescriptor if Event for clicking on the column

Hello,

Currently i have a GGC and i have a _ClickCell event on that grid.

 I use this event to see
 if the user has clicked on any column  in one specific column and perform some actions based on that.

I need it to dynamically add a summary row (GridSummaryRowDescriptor) for that column
with the sum (if it is a number) in the clicked column


Thanks in advance,

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, 

Code example 
this.gridGroupingControl1.TableControlCellClick += GridGroupingControl1_TableControlCellClick; 
 
private void GridGroupingControl1_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e) 
{ 
    if (e.TableControl.CurrentCell.MoveFromColIndex == e.TableControl.CurrentCell.ColIndex) 
        return; 
 
    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; 
            if (this.gridGroupingControl1.TableDescriptor.SummaryRows.Count > 0) 
                //Clear the previous summary rows to add the  
                this.gridGroupingControl1.TableDescriptor.SummaryRows.Clear(); 
 
            GridSummaryColumnDescriptor scd = new GridSummaryColumnDescriptor(); 
            scd.SummaryType = Syncfusion.Grouping.SummaryType.Int32Aggregate; 
            scd.Format = "{Sum}"; 
            scd.DataMember = columnName; 
            scd.Name = "SumOf" + columnName; 
 
            GridSummaryRowDescriptor srd = new GridSummaryRowDescriptor("Row1", scd); 
            this.gridGroupingControl1.TableDescriptor.SummaryRows.Add(srd); 
            //To update the summary. 
            this.gridGroupingControl1.TableDescriptor.EnsureSummaryDescriptors(); 
        } 
    } 
}

Hi Arulraj A

how to do that
1.
  after clicking the next column, GridSummaryColumnDescripto did not disappear
so that the second, third ...
2.
when we click the second time in the same column - it should disappear only in what we clicked a second time
- when we click the third time it adds again ..

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 
- when we click the third time it adds again
