Building grid in code
posted

I've written the following code using the example in the docs for creating a grid in code. Can anyone tell me why I get a null reference error on the grid.Columns property? If anyone has any other tips for creating a grid in code which is connected to a data source control please let me know.

Thanks.

        UltraWebGrid grid = new UltraWebGrid();
        grid.DataSourceID = "employeeDS";

        grid.Columns.Add(EmployeeFields.EmployeeId.Name, EmployeeFields.EmployeeId.Name);
        grid.Columns.Add(EmployeeFields.FirstName.Name, EmployeeFields.FirstName.Name);
        grid.Columns.Add(EmployeeFields.LastName.Name, EmployeeFields.LastName.Name);
        grid.Columns.Add(EmployeeFields.Title.Name, EmployeeFields.Title.Name);
        grid.Columns.Add(EmployeeFields.IsContracted.Name, EmployeeFields.IsContracted.Name);
        grid.Columns.Add(EmployeeFields.HourlyRate.Name, EmployeeFields.HourlyRate.Name);
        grid.Columns.Add(EmployeeFields.GuaranteedHours.Name, EmployeeFields.GuaranteedHours.Name);
        grid.Columns.Add(EmployeeFields.HourToPayIncrease.Name, EmployeeFields.HourToPayIncrease.Name);
        grid.Columns.Add(EmployeeFields.RateCode.Name, EmployeeFields.RateCode.Name);

        grid.DisplayLayout.AllowAddNewDefault = AllowAddNew.Yes;
        grid.DisplayLayout.AddNewRowDefault.Visible = AddNewRowVisible.Yes;
        grid.DisplayLayout.AddNewRowDefault.View = AddNewRowView.Top;

    OK, my fault. I solved this problem. I wasn't referencing the grid that I dropped onto the web form.

    I would however still like to know if anyone has any tips for building a grid in code.
