Hi,

I have some problems by right clicking on a treeview for displaying a contextmenu.
If I just rightclick an item on a treeview, the explorer rightmenu appears and my contextmenu.

Anyone knows how to resolve this !?

Thanx

Code: Visual Basic.NET

Copy

Hi,

That is usually because you did not return true from your ClientSideOnContextMenu handler. Here is a working example:

http://demo.essentialobjects.com/Default.aspx?path=TreeView\_i1\_i9

Click the JavaScript tab and you will notice the last line of the handler returns true.

Thanks!

hi
is following code correct ?

Quote:

function ShowContextMenu(e, treeView, node)
{ Node = node;
var menu = eo_GetObject("<%=ContextMenu1.ClientID%>");
document.getElementById("reply").value = node.getValue();
eo_ShowContextMenu(e, "<%=ContextMenu1.ClientID%>");
return true;
}

Hi,

That appears to be correct. In that case we will need to see the problem in order to find out why the default context menu is being displayed. If you have the page online, you can send us the Url and we will be happy to take a look and see what we can find. Otherwise we will need you to create a test page that duplicates the problem so that we can run and see the problem at here. As a test, you may also want to try your code inside a blank page to make sure that it has nothing to do with other code in your page.

Thanks!

Hi,

Try to add a small offset to your context menu. Change this:

Code: HTML/ASPX

Copy

....
<LookItems>
   <eo:MenuItem ...>
      <SubMenu ItemSpacing="1" ...>
      </SubMenu>
   </eo:MenuItem>
</LookItems>
....

Code: HTML/ASPX

Copy

....
<LookItems>
   <eo:MenuItem ...>
      <SubMenu OffsetX="3" OffsetY="3" ItemSpacing="1" ...>
      </SubMenu>
   </eo:MenuItem>
</LookItems>
....

Notice the new OffsetX and OffsetY added to the sub menu.

Please let us know if that fixes the issue.

Thanks!
