radDropDownButtonElement Click Event

[rahul]

Hi!


I have a radDropDownButtonElement in my Window Application I filled the radDropDownButtonElement with  Items (RadMenuItems) at runtime.So if one of these Item is clicked I have to do something. I'm not able to find any click event for this.so suggest me how should I make it?

Thank you for supporting me!

Hi, 

Example would be... 

1: Declare the drop down items that you are putting into your drop down button

Private WithEvents m_DropDownItem1 As Telerik.WinControls.UI.RadMenuButtonItem

2: In (for example) Form_Load, add the item

m_DropDownItem1 = New Telerik.WinControls.UI.RadMenuButtonItem("Click Me")
Me.RadDropDownButton1.Items.Add(m_DropDownItem1)

3: Handle the click event for the Drop Down Item

Private Sub DropDownItem_Clicked(ByVal sender As Object, ByVal e As EventArgs) Handles m_DropDownItem1.Click
    MessageBox.Show(m_DropDownItem1.Text)
End Sub

hope that helps
Richard

Hi rahul,

Thanks for the writing.

As Richard has suggested, you should manually subscribe to Items' Click event:
Please refer to the code below.

private void Form1_Load(object sender, System.EventArgs e)
{
     foreach (RadMenuItem currentItem in this.radDropDownButtonElement1.Items)
     {
          currentItem.Click += currentItem_Click;
     }
}

void currentItem_Click(object sender, System.EventArgs e)
{
      RadMenuItem currentItem = sender as RadMenuItem;
      Debug.Assert(currentItem != null, "Sender is not RadMenuItem");

      MessageBox.Show("'"+currentItem.Text + "' is clicked");
}

Richard, your Telerik points have been updated for the assistance.

I hope this helps.

Hi,

Greetings from Shabeer..



i Used the mentioned code for handling the click event, its handling only the first RadMenuItem click event.

I am using separator item in between and it has multilevel menus also.

Hello Shabeer,

Thank you for writing.

In case that you have Separators and Child Items in the Menu Items you should use the follow code:

private void Form1_Load(object sender, EventArgs e)
{
    foreach (RadItem currentItem in this.radDropDownButton1.Items)
    {
        RadMenuItem menuItem = currentItem as RadMenuItem;
        if (menuItem != null)
        {
            menuItem.Click += currentItem_Click;
            foreach (RadItem childItem in menuItem.Items)
            {
                RadMenuItem childMenuItem = childItem as RadMenuItem;
                if (childMenuItem != null)
                {
                    childMenuItem.Click += currentItem_Click;
                }
            }
        }
    }
}

I hope this helps. Regards,
