Hi Kins, 

Greetings from Syncfusion support. 

We have validated your query and we found that the record is updated by using the SetRowData method and this method will update the changes in the datasoure directly. Also the OnBatchSave event will not be triggered while updating the record using SetRowData method. Please find the validated sample below for your reference. 
 

If  you are facing any issues then kindly share us the below details, 

  1. Share us the exact problem/ more information on your query.
  2. Share us the video demo showing the reported problem.
  3. Share us the issue reproducing sample or reproduce the issue in the above provided sample.

Regards, 
Jeevakanth SP.

Thanks for reply..

Instead of "SetRowData" method, which method we are going to use to solve our above issue. Kindly revert back as soon as possible.


Note:

I have use below code to add new record from "external edit form".It works fine and batch handler also working fine.I would like to know how to do for record updating using external form

 public async Task AddRowInBatch()

{

 await gridRef.AddRecordAsync(styleBomLeatherSetup);

{

Hi Kins, 

We suspect that you want to save the cell by using methods. If so we suggest you  to use the UpdateCellAsync method, it will save the modified data in the cell and then when you click on the Update button in toolbar, then only it will update the values in the datasource. If you want to get the modified changes(cell saved changes) then use the GetBatchChanges method. 

Incase if you want to directly update the values in the datasource, you have to use the SetRowData method in which you cannot get changes after updating it. 


    public async Task Save() 
    { 
        if (SelectedData.OrderID != null)         
        { 
            //await this.Grid.SetRowData(SelectedData.OrderID, SelectedData); 
            var Index= await Grid.GetRowIndexByPrimaryKeyAsync(SelectedData.OrderID); 
            await Grid.UpdateCellAsync(Index, "CustomerID", SelectedData.CustomerID); 
            await Grid.UpdateCellAsync(Index, "Freight", SelectedData.Freight); 
            await Grid.UpdateCellAsync(Index, "OrderDate", SelectedData.OrderDate); 
            await Cancel(); 
        } 
    } 

API Reference: 

If this is not your scenario then kindly share the below details, 

  1. Do you want to update the changes directly to datasource or you want to save the changes to cell(Changes will be highlighted in that cell)
  2. Do you want to get the changes after saving the values in the cell?

Regards, 
Jeevakanth SP.
