    I have a batch edit grid, using 'cell' edit mode.  I have subscribed to the 'batchEditCellValueChanged' client side event.  I'm having extreme difficulty in finding out how to get the cell values from other cells in the same row.  The example is I have an 'amount' column where I want to add/subtract the entered amount into a selective total field outside the grid based on the ddl value from another cell in that same row.


    One major issue I came across is that adding new rows to the grid causes the index number obtained from 'args.get_row().rowIndex' does not then match up with the order of rows listed from the 'grid.get_masterTableView().get_dataItems()' method call... this issue having already been pointed out in another post, the result of which was the information passed on to Telerik dev team.


    Based on this information, how do I get other cell values from the same row during the 'batchEditCellValueChanged' event?

    Hello Austin,

    Within the OnBatchEditCellValueChanged event of the grid you can use the row's ID to get reference to the dataItem corresponding to that row. Once you have a reference to the dataItem you can use the get_cell(columnUniqueName) method for getting reference to the cell of a particular column and finally, use the BatchEditingManager getCellValue(cell) method for retrieving the value of that cell.

    For your convenience, following is a simple example demonstrating such implementation:
    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script type="text/javascript">
            function pageLoad() {
                //force the initialization of the data items
            function batchEditCellValueChanged(sender, args) {
                var batchManager = sender.get_batchEditingManager();
                var dataItem = $find(args.get_row().id);
                var idCell = dataItem.get_cell("ID");
                var idValue = batchManager.getCellValue(idCell);
    <telerik:RadGrid runat="server" ID="RadGrid1" OnNeedDataSource="RadGrid1_NeedDataSource">
        <MasterTableView EditMode="Batch">
            <ClientEvents OnBatchEditCellValueChanged="batchEditCellValueChanged" />

    And the dummy data:
    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        DataTable table = new DataTable();
        table.Columns.Add("ID", typeof(int));
        table.Columns.Add("FirstName", typeof(string));
        table.Columns.Add("LastName", typeof(string));
        table.Columns.Add("Age", typeof(int));
        table.Columns.Add("Date", typeof(DateTime));
        table.Columns.Add("BoolValue", typeof(Boolean));
        for (int i = 0; i < 5; i++)
            table.Rows.Add(i, "FirstName" + i, "LastName" + i, 20 + i, DateTime.Now.AddDays(i), i % 2 == 0);
        (sender as RadGrid).DataSource = table;

    Hope this helps.
