User-1614911347 posted
hello. i just wanna know if there is any way that i can take the page current url ( ex. hhtp://www.mysite.com/expo/something.aspx?IDsomething=1 ) and then compare it to the nodes navigateurl in a treeview so i can somehow expand the node acording after
navigation? the treeview is db generated - no xml and no sitemap - and it's placed on a masterpage.
tnx
if anyone wanna look at the code this is it:
the treeview:
<asp:TreeView
id="LinksTreeView"
EnableClientScript="true"
OnTreeNodePopulate="PopulateNode"
runat="server"
populatenodesfromclient="False"
NodeWrap="True"
ExpandDepth="1"
skinid="menuSkin">
<Nodes>
<asp:TreeNode
Text="Home"
SelectAction="Expand"
Value="Home"
NavigateUrl="~/Default.aspx"
PopulateOnDemand="True"/>
</Nodes>
</asp:TreeView>
the code behind:
protected void PopulateNode(Object sender,
TreeNodeEventArgs e)
{
// Call the appropriate method to populate a node at a particular level.
switch (e.Node.Depth)
{
case 0:
// Populate the first-level nodes.
PopulateMenu(e.Node);
break;
case 1:
// Populate the second-level nodes.
PopulateSomething(e.Node);
break;
case 2:
// Populate the third-level nodes.
PopulateItemsSomething(e.Node);
break;
default:
// Do nothing.
break;
}
void PopulateMenu(TreeNode node)
{
DataSet ResultSet = RunQuery("Select Something, Something, Url, From Menu");
if (ResultSet.Tables.Count > 0)
{
foreach (DataRow row
in ResultSet.Tables[0].Rows)
{
TreeNode NewNode =
new TreeNode(row["Something"].ToString(), row["IDSomething"].ToString());
NewNode.PopulateOnDemand = true;
NewNode.NavigateUrl = row["Url"].ToString();
node.SelectAction =
TreeNodeSelectAction.Select;
node.ChildNodes.Add(NewNode);
}
}
void PopulateSomething(TreeNode node)
{
// Query for the products of the current category. These are the values
// for the third-level nodes.
DataSet ResultSet = RunQuery("Select Something, IDSomething, IDMenu From Something Where IDMenu=" + node.Value);
// Create the third-level nodes.
if (ResultSet.Tables.Count > 0)
{
// Iterate through and create a new node for each row in the query results.
// Notice that the query results are stored in the table of the DataSet.
foreach (DataRow row
in ResultSet.Tables[0].Rows)
{
// Create the new node.
string colectiiValue =
"c" + row["IDSomething"].ToString();
TreeNode NewNode =
new TreeNode(row["Something"].ToString(), colectiiValue);
NewNode.SelectAction = TreeNodeSelectAction.Select;
NewNode.PopulateOnDemand =
true;
// Set additional properties for the node.
NewNode.NavigateUrl = string.Format("ro/Something/Something.aspx" +
"?IDSomething=" + row["IDSomething"].ToString());
// Add the new node to the ChildNodes collection of the parent node.
node.ChildNodes.Add(NewNode);
}
}
}
