Custom Shape drop down list

[Jacques]

Hi,

I have created a custom RadDiagramShape. I would like to be able to add a drop down list to my shapes so that the user would be able to select a certain value from a list in order to identify each shape. Or some alternative solution which will allow a user to select a value from a drop down list to be able to identify shape objects that are used on the diagram. I've attached an image to try and describe what i would like to achieve.

Thanks.

Hi Jacques,

In this case, you just need a RadHostItem which will allow you to add the drop-down list to the shape. Here is the code:

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();
        var dropdownShape = new DropdownShape()
        {
            Position = new Point(100, 100),
            ElementShape = new RoundRectShape(),
            BackColor = Color.Red

        };
        radDiagram1.AddShape(dropdownShape);

    }
}
class DropdownShape : RadDiagramShape
{
    RadDropDownList  radDropDownListElement1;
    protected override void CreateChildElements()
    {
        base.CreateChildElements();
        radDropDownListElement1 = new RadDropDownList();

        for (int i = 0; i < 10; i++)
        {
            radDropDownListElement1.Items.Add(i.ToString());
        }

        var host = new RadHostItem(radDropDownListElement1);
        this.DiagramShapeElement.Children.Add(host);

    }

}

Should you have any other questions do not hesitate to ask.
