Your code here is referring to UltraWebGrid. This is the UltraWinGrid forum. So I think you need to post your question in the WebGrid forum. 

Dear Mile,

I has assied a datset as datasource of the grid using the below statement

  DataTable Quot_Details = new DataTable();

 Quot_Details=ObjSupplyBL.GetbyIdSupplyquotationDetails(QuotationId, CompanyId, FinancialYearId);
                if (Quot_Details.Rows.Count > 0)
                {
                    ultraGridQuotationSummary.DataSource = Quot_Details;
                    ultraGridQuotationSummary.DataBind();
                }

is it possible for me to reassign the datasource of the grid to a datasat or a table?

I had use the below code to accomplish the same (maked the reassignment statements in bold),but when running the code i found the datasource becomming null.

is there any soution for this so that i can get the xml file from the datasource of the grid by assigning it to a dataset.

        private void GetValues(Control pParent)
            {
                foreach (Control ctrl in pParent.Controls)
                {
                    GetValues(ctrl);

                    if (ctrl is Infragistics.WebUI.UltraWebGrid.UltraWebGrid)
                    {
                        Infragistics.WebUI.UltraWebGrid.UltraWebGrid ugGrid = new Infragistics.WebUI.UltraWebGrid.UltraWebGrid();
                        ugGrid = (Infragistics.WebUI.UltraWebGrid.UltraWebGrid)ctrl;

                        DataSet ds = new DataSet();
                        ds = (DataSet)ugGrid.DataSource;

                        if (ds != null)
                        {
                            dsControlValues.Tables["ControlValues"].Rows.Add();
                            dsControlValues.Tables["ControlValues"].Rows[dsControlValues.Tables["ControlValues"].Rows.Count - 1]["ControlName"] = ugGrid.ID.ToString();
                            dsControlValues.Tables["ControlValues"].Rows[dsControlValues.Tables["ControlValues"].Rows.Count - 1]["ControlValue"] = ds.GetXml();
                        }
                    }

}
