Web Forms :: Setting Menu Selected Item From Code Behind?

Nov 10, 2010

I have a master page (Site.master) with a navigation menu linked to a datasource (Master.sitemap). I have a nested master page that has another navigation menu. For any item clicked in this nested navigation menu, I want a particular menu item in the Site.master navigation menu to be selected.

Here's my Site.master menu:
[Code]....

In my Site.master.cs I have this:
[Code]....

In the nested master page, Products.master I have this:
[Code]....

In the Products.master.cs file I try to change the selected item.
[Code]....

The master navigation and products navigation menus work just fine by themselves. But when I've tried to set the selected item of the master menu in the Page_Load above, I can't seem to access it. What I've found in trying to do this is the NavigationMenu seems to be uninitialized. The menu Items list is empty. What am I missing here? Why are there no menuItems in the Master.NavigationMenu control?

Web Forms :: Menu Top Level Selected Item Style?

Aug 22, 2010

I want to apply a css class to the level 1 menu item (parent) when it or any or it's children are selected. I've looked at MSDN documentation and any number of examples and walkthroughs but I haven't come up with a way of managing this. I was thinking something like this might work but the style is not being applied to the parent. To further complicate matters, if I try to apply a css style to StaticSelectedStyle it doesn't pick it up at all.

Menu Markup:
<StaticSelectedStyle Font-Bold="True" ForeColor="#3333CC" />
Code Behind:
protected void MenuItemClick_NavMenu(Object sender, MenuEventArgs e)
{menuItem parentItem = e.Item.Parent;
if (parentItem != null)
{
parentItem.Selected = true;
}

I tried using the the New ASP.NET Default Web Template in Visual Studio 2010 but one issue I'm encountering is with the CSS selected menu item and read apost which stated that...

"This screenshot demonstrates some of the styling options provided by the CSS, including the style for the selected About menu item"...In the screenshot the "About Us" menu item is highlighted but the page's content is the "Home" page content, not "About Us" page. My problem is...I can't get the selected item to be highlighted as in the screenshot even with fresh site using the built in template.

AJAX :: How To Set CSS Class For Selected Item In Menu Control

Feb 3, 2014

I've been trying to find an easy way of highlighting the current selected menu item of an asp.net menu (so the user knows which page they are on), but no matter what I have tried I can't get it to work. In my markup I have:

<asp:Menu SkinID="modulesMenu" DataSourceID="modulesSource" runat="server" ID="ModulesMenu"
OnMenuItemDataBound="ModulesMenu_MenuItemDataBound">
<StaticItemTemplate>
<div>
<asp:HyperLink ID="HyperLink2" CssClass="moduleName"

[Code] ....

 This is the c# side

protected void ModulesMenu_MenuItemDataBound(object sender, MenuEventArgs e) {
SiteMapNode siteMapNode = (SiteMapNode)e.Item.DataItem;
string pathStringFormat = IsNodeActive(siteMapNode) ? ConfigurationManager.AppSettings["ModuleImagePathFormatString_Active"] : ConfigurationManager.AppSettings["ModuleImagePathFormatString_Inactive"];

Web Forms :: Assigning Selected Item Of Radio Button List In Code Behind?

Mar 3, 2010

Since setting item.selected to true will lose the mutual behavior and setting list.SelectedValue (readonly) doesn't get any button selected.

I am using list.SelectedIndex to assign the selected button. as follow :

//step 1. find the item by value
ListItem item = list.items.FindByValue(obj.ToString());
//step 2. find the item index
list.SelectedIndex = list.Items.IndexOf(item);

I make it into an extension method. But feel stupid about this procedure to simply just assign a selected value. does anyone have a better approach?
