代碼背後的行更新用的UpdateMethod更新不是由ObjectDataSource控件「odsShiftDetails」支持的是： -

protected void gvShift_RowUpdating(object sender, GridViewUpdateEventArgs e) 
    { 
     try 
     { 
      TextBox txtShiftStartTime = (TextBox)gvShift.Rows[e.RowIndex].FindControl("ddlShiftStartTime"); 
      TextBox txtShiftEndTime = (TextBox)gvShift.Rows[e.RowIndex].FindControl("ddlShiftEndTime"); 
      TextBox txtWeekendShiftStartTime = (TextBox)gvShift.Rows[e.RowIndex].FindControl("ddlWeekendShiftStartTime"); 
      TextBox txtWeekendShiftEndTime = (TextBox)gvShift.Rows[e.RowIndex].FindControl("ddlWeekendShiftEndTime"); 
      Label lblUserecode = (Label)gvShift.Rows[e.RowIndex].FindControl("lblEditUserECode"); 

      string userecode = lblUserecode.Text.ToString(); 
      string _ShiftStart = txtShiftStartTime.Text.ToString(); 
      string _ShiftEnd = txtShiftEndTime.Text.ToString(); 
      string _WeekendShiftStart = txtWeekendShiftStartTime.Text.ToString(); 
      string _WeekendShiftend = txtWeekendShiftEndTime.Text.ToString(); 

      EmployeeQuotientCL.Entities.ConfigurationVariables _configVariables = new ConfigurationVariables(); 
      string databaseConnectionString = _configVariables.ConnectionString; 
      SqlConnection sqlConnection = null; 
      if (((databaseConnectionString + string.Empty) != string.Empty)) 
      { 
       DBConnect dbConnect = new DBConnect(_configVariables.ConnectionString); 
       sqlConnection = dbConnect.SQLConnection; 
       SqlCommand cmd = new SqlCommand(); 
       cmd.Connection = sqlConnection; 
       cmd.CommandText = "UPDATE UserInfo SET ShiftStartTime ='" + _ShiftStart + "',ShiftEndTime='" + _ShiftEnd.ToString() + "',Weekendshiftstarttime='" + _WeekendShiftStart.ToString() + "',Weekendshiftendtime='" + _WeekendShiftend.ToString() + "' WHERE UserECode=" + userecode.ToString(); 
       sqlConnection.Open(); 
       cmd.ExecuteNonQuery(); 
       gvShift.DataSource = null; 
       gvShift.DataBind(); 
       sqlConnection.Close(); 
      } 
     } 
     catch (Exception ex) 
     { 
     } 
    } 

雖然更新在網格中的行，我得到了低於錯誤信息。

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: >Updating is not supported by ObjectDataSource 'odsShiftDetails' unless the UpdateMethod is >specified.

指導我如何解決這個錯誤。提前致謝。

你需要添加一個更新方法到你的gridview。看看本教程：Gridview ObjectdataSource
