Question about MasterGridViewTemplate and MasterTemplate

[Martin Horst]

Hi,

the MasterGridViewTemplate is marked as obsolete so I tried to use the
MasterTemplate property inside the designer. But this is not possible because
the new MasterTemplate property is also marked as not browsable. Why is it not
allowed to this property inside the designer any more.

Regards
Martin

Hello Martin Horst,

Thank you for contacting us.

In the new version we exposed all MasterGridViewTemplate properties to the RadGridView control, so there is no need of the MasterTemplate at design-time. In addition, from the smart tag you can change DataSource, Columns, Templates, Relations, FilterDescriptors, GroupDescriptors, SortDescriptors of the MasterTemplate object.

I hope this information is useful. Let me know if you need further assistance.

Sincerely yours,

what if we want to programmatically edit the template to get a certain type of functionality and link it to a gridview we create in the designer?

Hi Anders,

You can override the default RadGridViewElement and the MasterGridViewTemplate to add your custom properties and behavior. Here is an example:

using System.Windows.Forms;
using Telerik.WinControls.UI;
using Telerik.WinControls.UI.Data;

namespace Lab.Grid
{
    public partial class GridOverrideViewAndTemplateForm : Form
    {
        class MyMasterTemplate : MasterGridViewTemplate
        {
            public MyMasterTemplate()
            {
                this.DataSource = new ValueList<double>(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
            }
        }

        class MyGridViewElement : RadGridViewElement
        {
            protected override MasterGridViewTemplate CreateTemplate()
            {
                return new MyMasterTemplate();
            }
        }

        class MyGrid : RadGridView
        {
            protected override RadGridViewElement CreateGridViewElement()
            {
                return new MyGridViewElement();
            }
        }

        public GridOverrideViewAndTemplateForm()
        {
            InitializeComponent();

            MyGrid grid = new MyGrid();
            grid.Dock = DockStyle.Fill;
            grid.Parent = this;
        }
    }
}

I hope this helps.
