How to define Height of GroupColumnDescription ?

I have a custom cell as below, so RowHeight = 200, if i do groupping, GroupColumnDescription  Height becomes also 200. Is it possible to define or reduce the height of GroupColumnDescription ?

Hi Emil, 
 
Thanks for contacting Syncfusion Support. 
 
We have checked your query. You can achieve your requirement by using SfDataGrid.QueryRowHeight event. Please refer the below code snippet for more details. 
private void DataGrid_QueryRowHeight(object sender, QueryRowHeightEventArgs e) 
{ 
    var rowData = dataGrid.GetRecordAtRowIndex(e.RowIndex); 
    if(rowData == null && e.RowIndex != 0) 
    { 
        e.Height = 100; 
        e.Handled = true; 
    } 
} 
  
In the above snippet, we get the row data and checked whether the row is caption summary row or record row. If the row is caption summary row, then we have applied the row height. 
Also, we have attached the sample for your reference and you can download the same from the below link. 
 
Regards, 
Divakar.

Hi Emil, 

Please ignore our previous update. 

You can achieve your requirement by hadling SfDataGrid.QueryRowHeight event. Please refer the below code example 
dataGrid.QueryRowHeight += DataGrid_QueryRowHeight; 

private void DataGrid_QueryRowHeight(object sender, QueryRowHeightEventArgs e) 
{ 
    if (SfDataGridHelpers.IsCaptionSummaryRow(this.dataGrid, e.RowIndex)) 
    { 
        e.Height = 100; 
        e.Handled = true; 
    } 
} 
  
Regards, 
Ashok

Hi Ashok,

thanks fro your help but it still didnt make any change for me. I am still getting same exception as below 
This is only happening if I click expand and try to collapse last group again.

I made several further tests and I recognized that it only occurs for last group. Basically I cannot collapse the last group when I use QueryRowHeight event. It throws this exception everytime. If i dont use QueryRowHeight, using default, everything works fine.

EM Emil December 13, 2016 04:36 PM UTC

Further more information, my datagrid is defined as below, as you can see RowHeight is defined 200, If I remove this, it doesnt crash because It will automatically resize as same height as group caption. So from that I understand it that it occurs only when row height is different than caption height
