Hi,
Try the following code snippet to access new value from the controls in Updatecommand event.
C#:
protected void radgrid1_UpdateCommand(object sender, GridCommandEventArgs e)
  {
     GridEditableItem editItem = e.Item as GridEditableItem;
     Hashtable newValues = new Hashtable();
     TextBox txt = ((TextBox)editItem.FindControl("textbox1"));
     string value = txt.Text;// to get the value of a textbox which is in EditItemTemplate
     e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editItem);
     string id = newValues["EmployeeID"].ToString();// access by column uniquename
  }

Thanks,
Princy.

Hello,

Please use advancedatabinding method (needdatasource event) to assign/bind datasource to RadGrid. For more info. please check below code snippet.

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/needdatasource/defaultcs.aspx


You are not able to get updated value because before you reach or execute the Update command, you are re-assigned datasource to your RadGrid.


Thanks,
Jayesh Goyani

I'm using EditMode="Batch" BatchEditingSettings-EditType="Cell".
Why I receive this error?  "Specified argument was out of the range of valid values. Parameter name: index".  Please refer to the PNG file.
my code:

Protected Sub RadGrid1_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs)
        Dim mydts As DateTime = DateTime.Now

        Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)
        'Get the primary key value using the DataKeyValue.
        'Dim EmployeeID As String = editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)("EmployeeID").ToString()
        'Access the textbox from the edit form template and store the values in string variables.
        'Dim LastName As String = (TryCast(editedItem("LastName").Controls(0), TextBox)).Text
        'Dim FirstName As String = (TryCast(editedItem("FirstName").Controls(0), TextBox)).Text
        'Dim Title As String = (TryCast(editedItem("Title").Controls(0), TextBox)).Text
        'Dim Address As String = (TryCast(editedItem("Address").Controls(0), TextBox)).Text
        'Dim City As String = (TryCast(editedItem("City").Controls(0), TextBox)).Text

        'Dim LastName As String = (TryCast(editedItem("LastName").Controls(0), TextBox)).Text
        Dim DIVISION As String = (TryCast(editedItem("DIVISION").Controls(0), TextBox)).Text
        Dim DISTRICT As String = (TryCast(editedItem("DISTRICT").Controls(1), TextBox)).Text
        Dim LOCATION As String = (TryCast(editedItem("LOCATION").Controls(2), TextBox)).Text
        Dim FROM_YEAR As Integer = (TryCast(editedItem("FROM_YEAR").Controls(3), TextBox)).Text
        Dim FROM_WEEK As Integer = (TryCast(editedItem("FROM_WEEK").Controls(4), TextBox)).Text
        Dim TO_YEAR As Integer = (TryCast(editedItem("TO_YEAR").Controls(5), TextBox)).Text
        Dim TO_WEEK As Integer = (TryCast(editedItem("TO_WEEK").Controls(6), TextBox)).Text
        'Dim USERID As String = (TryCast(editedItem("USERID").Controls(0), TextBox)).Text
        Dim USERID As String = Session("currUserID")
        'Dim USERNAME As String = (TryCast(editedItem("USERNAME").Controls(0), TextBox)).Text
        Dim USERNAME As String = Session("currUserName")
        Try
            Dim strConnect As New OracleConnection()
            Dim strEnvironment As String = Session.Item("Environment")
            Dim m_strFASConnectionString As New OracleConnection()
            Dim objMiscHelperFunctions As New MiscHelperFunctions(strEnvironment)
            Dim m_oraFASConn As OracleConnection
            m_strFASConnectionString.ConnectionString = objMiscHelperFunctions.GetFASConnectionString()
            OracleConnection = New OracleConnection(m_strFASConnectionString.ConnectionString)
            'Open the SqlConnection
            OracleConnection.Open()
            'Update Query to update the Datatable
            Dim updateQuery As String = "UPDATE WFM_CAT_RECURRENCE_DT set DIVISION='" & DIVISION & "',DISTRICT='" & DISTRICT & "',LOCATION='" & LOCATION & "',FROM_YEAR='" & FROM_YEAR & "',FROM_WEEK='" & new_From_Week & "',TO_YEAR='" & TO_YEAR & "',TO_WEEK='" & new_To_Week & "',USERID='" & USERID & "',USERNAME='" & USERNAME & "',CREATE_DATE=sysdate WHERE DIVISION= " & DIVISION & " AND DISTRICT = " & DISTRICT & " AND LOCATION = " & LOCATION & " AND FROM_YEAR = " & FROM_YEAR & " AND FROM_WEEK = " & old_From_Week & " AND TO_YEAR = " & TO_YEAR & " AND TO_WEEK = " & old_To_Week & ""

            OracleCommand.CommandText = updateQuery
            OracleCommand.Connection = OracleConnection
            OracleCommand.ExecuteNonQuery()
            'Close the SqlConnection

 

            OracleConnection.Close()
        Catch ex As Exception
            RadGrid1.Controls.Add(New LiteralControl("Unable to update record. Reason: " + ex.Message))
            e.Canceled = True
        End Try

    End Sub
