How to dynamically set the Title of SiteMap from MasterPage? - asp.net

Question

In My Web.sitemap I have the following:
<siteMapNode url="~/Groups/ViewGroups.aspx" urlRoute="groups/{PostId}/{PostTitle}" />
</siteMapNode>
In my MasterPage I have implemented the ItemDataBound event to try and set the title of each page that implements the master page dynamically but for some reason the title is not being set.
protected void SiteMapPath1_ItemDataBound(object sender, SiteMapNodeItemEventArgs e)
{
string CurrentNodeTitle = GetTitleFromDatabase();
if (e.Item.ItemType == SiteMapNodeItemType.Current) {
e.Item.SiteMapNode.Title = CurrentNodeTitle;
}
}
I also tried this in the ItemCreated event but still it did NOT work.
If I set the title in the Web.sitemap then it works perfectly but when I set it using e.Item.SiteMapNode.Title = CurrentNodeTitle; the title is nto being set.

Answer 1

Try this.
private string currentKey = SiteMap.CurrentNode.Key
protected void SiteMapPath1_ItemDataBound(object sender, MenuEventArgs e)
{
string CurrentNodeTitle = GetTitleFromDatabase();
if (e.Item.DataPath == currentKey){
e.Item.Text = CurrentNodeTitle;
}
}
Edit note:
it should be MenuEventArgs

This question is about 6 years old now, and the one answer is completely wrong and should probably be deleted. I had a hard time finding the answer - it's not nearly as straight forward as I would have expected it to be, but the answer is pretty simple nonetheless.
Using the static SiteMap classes SiteMapResolve event from the System.Web namespace (NOT your instance of SiteMapPath!) you can manipulate the URL and Title on the fly.
In my case, I have a custom localization method that retrieves the localized strings from a database. The sitemap title's contain the key used to identify the string. This is the code behind for my Master Page:
protected void Page_Load(object sender, EventArgs e)
{
// ...
SiteMap.SiteMapResolve += (o, args) =>
{
if (SiteMap.CurrentNode == null)
return null;
SiteMapNode currentNode = SiteMap.CurrentNode.Clone(true);
currentNode.Title = SessionObject.LocalizeText(currentNode.Title);
SiteMapNode tempNode = currentNode;
while (tempNode.ParentNode != null)
{
tempNode = tempNode.ParentNode;
tempNode.Title = SessionObject.LocalizeText(tempNode.Title);
}
return currentNode;
};
// ...
}
Then in your Master Page ASPX (or presumably any ASPX page that utilizes this Master Page), you can add <asp:SiteMapPath runat="server" ... /> and it should be processed by the SiteMapResolve event.
