Adding context menu dynamically giving error

[shadow]

I am trying to show a context menu on mouse over of an image control.

Below is my code

           

Dim ControlsContainer As New Panel
           Dim InfoIcon As New Image
           Dim InfoContextMenu As New RadContextMenu
           Dim mi As New RadMenuItem






           ControlsContainer.ID = "pnlInfoContainer"




           InfoIcon.ID = "InfoImageIcon"
           InfoIcon.ImageUrl = "/mb/admin/images/plus.png"
           InfoIcon.Attributes.Add("onmouseover", "ShowInfoMenuOnLeftClick();")




           InfoContextMenu.ID = "mb_InfoContents_ContentextMenu"
           InfoContextMenu.ClientIDMode = System.Web.UI.ClientIDMode.Static




           mi.Text = "Home"
           InfoContextMenu.Items.Add(mi)




           ControlsContainer.Controls.Add(InfoIcon)
           ControlsContainer.Controls.Add(InfoContextMenu)




           Dim script As String = "<script type=""text/javascript""> function ShowInfoMenuOnLeftClick(sender, args) {     var contextMenu = $find('mb_InfoContents_ContentextMenu'); console.log(contextMenu); contextMenu.show(args); } </script>"
           If Not Me.Page.ClientScript.IsStartupScriptRegistered("InfocontentsMenu") Then
               Me.Page.ClientScript.RegisterStartupScript(Me.Page.GetType, "InfocontentsMenu", script)
           End If


           Me.Controls.Add(ControlsContainer)




           Dim MenuTargetConfiguration As New ContextMenuControlTarget()
           MenuTargetConfiguration.ControlID = "InfoImageIcon"
           InfoContextMenu.Targets.Add(MenuTargetConfiguration)

I am getting a java script error with this code..

1. Uncaught TypeError: Cannot read property 'target' of undefined Telerik.Web.UI.WebResource.axd:4660
   1. a.RadContextMenu.showTelerik.Web.UI.WebResource.axd:4660
   2. ShowInfoMenuOnLeftClickindex.aspx:560
   3. onmouseover

Can you help me!!

Hello Farid,

I prepared a sample project that demonstrates how you can find the RadContextMenu when is either created in code behind or in the markup. I would also recommend you take a look at this online demo that shows how a context menu pops up on image hover.

Hope that this will lead you into right direction.
