QueryCellInfo and GetRecordFromRow

Hi all,

I'm using syncfusion GridDataControl and I need to set ToolTip for each row. 

I use Behavior<GridDataControl> and QueryCellInfo event. I get row by AssociatedObject.Model.Table.GetRecordFromRow(e.Cell.RowIndex) code. Everything was good before I group data by one of column. After I do this GetRecordFromRow stop to work. Some rows I can handle by this code

                        if (AssociatedObject.Model.Table.HasGroups)
                            rowIndex = e.Cell.RowIndex - 1;
But this workaround isn't help for all rows.

Hi Rajasekar,

I've attached sample. When I expanded groups I'm getting exception ArgumentOutException. Even if I wrap it by try catch It will ask only about last row as I can see from debugger. 

This code is working if I remove grouping.

Hi Eugene,

We have analyzed your issue, there is no corresponding record for the row index when you expand the row. It is the cause of exception. You can get the record by using Record API. You can refer the below codesnippet.


void OnQueryCellInfo(object sender, GridQueryCellInfoEventArgs e)


var style = e.Style as GridDataStyleInfo;

var data = style.CellIdentity;

var record = data.Record as Customers;



We have prepared a sample based on this. Please find the attached sample below.

Please let us know if you need further assistance.
