How to get the toplevel control of a RadMenuItem

[Hardy]

Hi all,

I like to get the top level control of a RadMenuItem.
For example: there is a RadForm with two RadGridView controls.
Each containing a ContextMenu. For both I'm using the same handler which should recognize on which RadGridView the menu is clicked.
How can I retrieve the  RadGridView which is the top level for the ContextMenu?

Regards

Hello Hardy,

Thank you for writing.

You can save the grid instance in the Tag property of the menu and later retrieve it in the click event handler. Here is a small sample:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        Random r = new Random();
        DataTable table = new DataTable();
        table.Columns.Add("ID", typeof(int));
        table.Columns.Add("Name", typeof(string));
        table.Columns.Add("Bool", typeof(bool));
        table.Columns.Add("DateColumn", typeof(DateTime));

        for (int i = 0; i < 10; i++)
        {
            table.Rows.Add(i, "Row " + i, r.Next(10) > 5 ? true : false, DateTime.Now.AddHours(i));
        }

        this.radGridView1.DataSource = table;
        this.radGridView2.DataSource = table;

        RadMenuItem item = new RadMenuItem("item");
        item.Click += item_Click;
        menu.Items.Add(item);

        radGridView1.ContextMenuOpening += radGridView1_ContextMenuOpening;
        radGridView2.ContextMenuOpening += radGridView1_ContextMenuOpening;
    }

    RadContextMenu menu = new RadContextMenu();

    void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
    {
        e.ContextMenu = menu.DropDown;
        menu.DropDown.Tag = sender;
    }

    void item_Click(object sender, EventArgs e)
    {
        RadMenuItem item = (RadMenuItem)sender;
        RadGridView grid = (RadGridView)item.OwnerControl.Tag;
    }

I hope that you find this information useful.

Hi Stefan,

it's a possible workaround.
I would like to get a property like menu.parent or menu.toplevelcontrol...
Using the tag property is ok but in my solution I'm using the tag for other information.

I solved the problem using a lookup table where any menu is stored with its grid
Now I can select the menu's parent from the table.

Hello Hardy,

I am glad that you have found a suitable solution for your case.

The parent of the menu items will be the element from the popup element tree, and since this popup is not part of the control, you cannot find the control in the element tree.

Since you mention that the tag of the context menu was already taken, you can create a custom object that will hold both your object and the parent or you can use the Tag of the menu item.

I hope that you find this information useful.
 
All the best,
