Export from gridgroupingcontrol not exported as numeric

I am using gridgroupingcontrol to show data.
Then it is exported to excel 

I have not done any special formating to the gridgroupingcontrol columns
The grid shows all numeric values but when i export to excel the data is exported as string in excel

How can I fix this

Hi Remmie,

Thank you for contacting Syncfusion Support.

If you want to export the Numeric value to the excel, it can be achieved by setting the CellValueType of particular column. If the CellValueType is not specified for the columns, it takes the data on it’s as the general type or text. Therefore the numeric value is also treated like the string while exporting. if you want to display the exported value as Numeric, need to set the CellValueType in the GridGroupingControl or while creating the data source specify the Column value type as double (or) int.

If you are using whole table as the numeric value then you can set the CellValueType of the table as follows,
Code Snippet:

//Set the CellValue type for Grid
this.gridGroupingControl1.Appearance.AnyRecordFieldCell.CellValueType = typeof(double);

//Set the CellValueType for particular column which is want to be exported as Numeric
this.gridGroupingControl1.TableDescriptor.Columns["ColumnName"].Appearance.AnyRecordFieldCell.CellValueType = typeof(int);

Thank you Adhi

it exports now as numeric when i made the column of type decimal.

However there is one minor issue -
decimal values like 1.00 is exported as 1  , 4.50 is exported as 4.5 
I mean it loses the decimal 0 in excel . in the grid it is showing fine only problem is in the excel

How can that be fixed

Hi Remmie,

Thanks for your update.

We were unable to reproduce the issue at our end. It might be caused by the use of different Converter for exporting. Instead, use the GroupingGridExcelConverterControl to export the columns with the decimal values. Please refer to the following code example,

Code Example:

private void button1_Click(object sender, EventArgs e)


    //Create Converter for exporting

    GroupingGridExcelConverterControl converter = new GroupingGridExcelConverterControl();

    SaveFileDialog saveFileDialog = new SaveFileDialog();

    saveFileDialog.Filter = "Files(*.xls)|*.xls";

    saveFileDialog.DefaultExt = ".xls";

    if (saveFileDialog.ShowDialog() == DialogResult.OK)


        //Export the Grid to excel

        converter.GroupingGridToExcel(this.gridGroupingControl1, saveFileDialog.FileName, Syncfusion.GridExcelConverter.ConverterOptions.Default);

        if (MessageBox.Show("Do you wish to open the xls fnnile now?", "Export to Excel", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)


            Process proc = new Process();

            proc.StartInfo.FileName = saveFileDialog.FileName;
