Set Session variable on menu item's click in asp.net

Mark Devid 3729 08 Oct 2014

ASP newbie here, in my website I need to set a session variable when I click the menu item

How can I achieve this, I have a menu control in my master page which has a sitemap file attached to it?


<asp:Menu ID="mainMenu" runat="server" DataSourceID="siteMapSource"
    StaticDisplayLevels="10" Width="150px">
    <StaticSelectedStyle CssClass="menuNodeSelected" />
    <LevelMenuItemStyles>
        <asp:MenuItemStyle Font-Bold="True" Font-Underline="False" />
    </LevelMenuItemStyles>
    <StaticMenuItemStyle CssClass="menuNode" />
</asp:Menu>
<asp:SiteMapDataSource ID="siteMapSource" runat="server" ShowStartingNode="False" />

<asp:Menu ID="mainMenu" runat="server" DataSourceID="siteMapSource"
    StaticDisplayLevels="10" Width="150px"
    OnMenuItemClick="NavigationMenu_MenuItemClick">
    <StaticSelectedStyle CssClass="menuNodeSelected" />
    <LevelMenuItemStyles>
        <asp:MenuItemStyle Font-Bold="True" Font-Underline="False" />
    </LevelMenuItemStyles>
    <StaticMenuItemStyle CssClass="menuNode" />
</asp:Menu>
<asp:SiteMapDataSource ID="siteMapSource" runat="server" ShowStartingNode="False" />

You should set a method to be called on server side OnMenuItemClick, this will rise the event of menu click. That event is (in our case): NavigationMenu_MenuItemClick.

On Code-Behind you can do whatever you want when an menu item is selected.

void NavigationMenu_MenuItemClick(Object sender, MenuEventArgs e)
        {
            // Display the text of the menu item selected by the user.
            Message.Text = "You selected " + e.Item.Text + ".";
            Session["variable"] = e.Item.Text;
        }
