Can you post your code? I'm not sure what you mean by "stringbuilder table".

Ok. Now I understood. Instead of using html table you need to use asp.net datagrid to provide edit functionality. Please go through below link for more details on how to implement edit/update/ delete functionality in datagrid. http://www.c-sharpcorner.com/UploadFile/rahul4_saxena/BasicoperationsofDataGrid05022007081224AM/BasicoperationsofDataGrid.aspx http://www.c-sharpcorner.com/UploadFile/lcamlibel/datagridwebcontrol02122007040915AM/datagridwebcontrol.aspx http://www.codeproject.com/KB/aspnet/Edit_and_Delete_Data.aspx

thanks for your reply. The above code binds the data from a database into a table. Now what i need to do is: there will be one edit button on a form. If a user check on a checkbox in table and Click on a edit button, he should be able to edit the respective data. Could you provide me a sample code if possible.

You can insert new string or replace existing string in StringBuilder. But for your requirement there is only one way to edit StringBuilder, which is, re-create new StringBuilder with new value. Also can you explain little bit more on what exactly you want to do. I see you are assigning StringBuilder variable ShowDetails into session, but wanted to know what exactly you want to edit, it will be good if you can provide some scenario.

Here is my code for binding data in a stringbulider. The given below code binds data in a table. Now i need to edit those data when required. How is it possible to do? protected void bindData() { StringBuilder ShowDetails = new StringBuilder(); divShow.Style.Add("display", "none"); string myquery = "select sId, sEmpName, dtYear, dtMonth, sSalary from tblSalarySheet where sStatus='A' and dtYear='"+ ddListYear.SelectedItem.Text +"' and dtMonth='"+ ddlistMonth.SelectedItem.Text +"'"; int rowNum = 1; string conn = ConfigurationSettings.AppSettings["SqlConn"]; SqlConnection MyConn = new SqlConnection(conn); SqlCommand cmd = new SqlCommand(myquery, MyConn); SqlDataReader reader; try { MyConn.Open(); reader = cmd.ExecuteReader(); if (reader.HasRows) { divShow.Style.Add("display", "block"); rowNum = 1; while (reader.Read()) { if (rowNum % 2 == 0) ShowDetails.Append(" "); else ShowDetails.Append(" "); ShowDetails.Append(" "); ShowDetails.Append(" " + reader["sId"].ToString().Trim() + " "); ShowDetails.Append(" " + reader["sEmpName"].ToString().Trim() + " "); ShowDetails.Append(" " + reader["dtYear"].ToString().Trim() + " "); ShowDetails.Append(" " + reader["dtMonth"].ToString().Trim() + " "); ShowDetails.Append(" " + reader["sSalary"].ToString().Trim() + " "); " "); rowNum++; ShowDetails.Append(" "); } Session["sID"] = ShowDetails.ToString(); } else { divShow.Style.Add("display", "none"); } reader.Close(); } catch { } finally { MyConn.Close(); cmd.Dispose(); } }
