Access the Spreadsheet workbook on the server

HOW TO

Access the Spreadsheet workbook on the server.

SOLUTION

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
