Access the Spreadsheet workbook on the server


Access the Spreadsheet workbook on the server.


When pressing the Save button in the Spreadsheet or calling programmatically the .save() client-side method, you can access the Spreadsheet workbook on the server by using one of the following approaches:

  • Use a Custom Provider and the Workbook will be available in the SaveWorkbook method.
  • Parse the Request.Params["__CALLBACKPARAM"] property value by using the .FromJson() method of the static Telerik.Web.Spreadsheet.Workbook class. For example:
protected void Page_Load(object sender, EventArgs e)
    if (IsCallback && Request.Params["__CALLBACKID"] == RadSpreadsheet1.UniqueID)
        Workbook workbook = Telerik.Web.Spreadsheet.Workbook.FromJson(Request.Params["__CALLBACKPARAM"]);
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If IsCallback AndAlso Request.Params("__CALLBACKID") = RadSpreadsheet1.UniqueID Then
        Dim workbook As Workbook = Telerik.Web.Spreadsheet.Workbook.FromJson(Request.Params("__CALLBACKPARAM"))
    End If
End Sub
