RadMenu Item Click-- New Widow

[Jagat]

Hello ,

  I have a RadMenu in my web application. For one of the Rad Menu Item, I would like to open the form in new window. I have tried the Target="_blank". It is not working. I also tried through javascript
function clickHandler(sender, eventArgs)
          {    
        
              if (eventArgs.item.Text == "LunchBreak")
              {
                   //open a pre-defined window from the RadWindowManager's
                   //Windows collection
                  radopen(null,"Window1");
                  //Cancel the postback
                  return false;
              }
          }

 <telerik:RadMenu ID="RadMenu1" runat="server" orientation="Horizontal" Skin="Windows7" OnClientItemClicking="clickHandler"

           <telerik:RadWindow ID=Window1 runat=server NavigateUrl="frm_BreakTime.aspx" />  
       </Windows>  
   </telerik:RadWindowManager>

Hello,
 Just a small update on my question..
 I have tried Target= parent also. that didn't work too.
I followed the code behind sample in the link below.

Hello Jagat,

Try the following code snippet to open a window from MenuItemClick.

C#:

protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)
  {
 if (e.Item.Text == "Break")
     {
         RadWindow rw = new RadWindow();
         rw.Width = Unit.Pixel(260);
         rw.Height = Unit.Pixel(300);
         rw.NavigateUrl = "Window.aspx";
         rw.VisibleOnPageLoad = true;
         RadWindowManager1.Windows.Add(rw);
     }
  }

JS:

<script type="text/javascript">
function OnClientItemClicking(sender,eventArgs)
 {
   if(eventArgs.get_item().get_text()=="LunchBreak")
      {
        radopen(null,"window.aspx");
        return false;
      }
 }
</script>

Thanks,
Shinu.

New window is opening but i have a problem. Suppose, I am in form which has Radgrid in it and when I click the menu item here, the new window is opening but, when i close that new window and edit the grid, the new window is opening again. For each and every postback in the old window, the new window is opening.

Thanks

Hi Jagat,

Can you provide markup of the scenario that you describe in the previous forum post?

Thanks in advance.

Hi, I had the same problem, I just altered the "VisibleOnPageLoad" and set it to "false"
Works fine now 

 

if (e.Item.Text == "New Single Instrucion")

{

 

RadWindow rw = new RadWindow();

rw.Width =

 

Unit.Pixel(260);

rw.Height =

 

Unit.Pixel(300);

rw.NavigateUrl =

 

"newwo.aspx";

rw.VisibleOnPageLoad =

 

false;

rw.Skin =

 

"Transparent";

　

RadWindowManager1.Windows.Add(rw);

Hello Ridwaan,

When you are setting VisibleOnPageLoad property as true, the window will open each time after a postback. Check the following sticky thread which explains how to open window from server side.
