View 2 RepliesI am trying to extend the TreeView and TreeNode class and use it in an .aspx page. My development environment is VS 2005. I put the following code inside of a single .cs file in my App_Code folder:
public class MyTreeview : TreeView {
protected override void TreeNode CreateNode() { return new MyTreeNode(); }
}
public class MyTreeNode: TreeNode { public MyTreeNode():base(){} }
I want to now use my inherited Node and TreeView in my .aspx file. I have the following directive, which is throwing an error -> File is in the special directory App_Code which is not allowed. I tried putting everything into an .ascx file, but I think I am not specifying the class and inheritance directives correctly.

I've encountered a problem when I put a treeview in a page which is using master page. The treeview style doesn't apply.For example, I set the nodes with different colors in different levels. But the treeview nodes are still displayed in the default color(bule).
The treeview code is :
[Code]....
If I use these code in a page which doesn't use a master page. The nodes are shown in colors.
I m using this code
Menu menu = new Menu();
menu.MenuItemClick += new MenuEventHandler(menu_MenuItemClick);
menu.BackColor = System.Drawing.Color.AliceBlue;
But i want that background color of menu should be seprate two Different color red and AliceBlue
I couldn't find one that fit for the Treeview control. I have successfully binded my XmlDataSource to my Treeview control. Here is the XML
<ROOT rootName="Sales Literature Groups">
<saleslit_group slgrp_id="1" slgrp_name="PLCs" slgrp_loc="3A">
<sales_literature saleslit_id="1" saleslit_description="Literature #1" is_tube_mailer="0"/>
<sales_literature saleslit_id="2" saleslit_description="Literature #2" is_tube_mailer="0"/>
<sales_literature saleslit_id="3" saleslit_description="Literature #3" is_tube_mailer="1"/>
</saleslit_group>
</ROOT>
My question is whether it is possible or not to extract the "is_tube_mailer" field from the Treeview's Treenode. I attempted to cast the node.DataItem to an Xmlnode, however that only seemed to work in the TreeNodeDataBound event. I need to do this within a Button.Click event routine.
I would like to set text attribute of a treenode. But I want to do this in HTML. I tried it:
<asp:TreeNode
Text="<% =session['var'] %>"
SelectAction="Expand"/>
but it does not work.
i am using a context menu for each treenode, the example i am using has front end code as
<asp:TreeNode Text="<b id='b1' oncontextmenu="return ShowContextMenu(event, 'Panel2')" > this is a test</b>" Value="sLeaf 1" ></asp:TreeNode>
this works fine but i need to add text via the code behind. when i do this the html is not converted and is displayed as text.
TreeNode tn = new TreeNode();
tn.Text = Server.HtmlEncode(string.Format("<b oncontextmenu='return ShowContextMenu(event, '{0}')'>{1}</b>", pnlContextSites.ClientID, site_item.SiteName));
tn.Value = site_item.Id.ToString();
tn.SelectAction = TreeNodeSelectAction.Select;
how can i fix this?
I don't get it... why am I getting the error "'TreeNode' does not contain a definition for 'SelectAction'"
This is s .net 3.5 site here is the code behind... I have red squiggles under node.SeletAction, node.opulateOnDemand, node.expand, node.value...

I have a treeview with ID treeview1 which gets populated from xmlresponse somelike like:
<root>
<Products ProductID="1" type="Electronics">Television</Products>
<Property ID="New" division="Category" count="50"></Property>
<Products ..../>
<Property .../>
</root>
I get Television displayed as treenode. Now I have two issues:
1) if i click on Television i need to make a new xmlrequest based on its ProductID. I tried to bind TreeView1.selectednode.value as property innertext in my xmlrequest but it doesn't accept it. However, I am puzzled how to use xpath @selected to get this particualr clicked node ProductID to be passed as Property innertext.
2) I need to diplay in treeview1 something like : Television(50). So, how to append count to televsion here.
How can achive this. I have tried the following
ScriptManager.RegisterStartupScript(this, this.GetType(), "Refresh", "<script language='javascript'>window.top.parent.location = " + Session[lObjClsGlobals.mStrViewStateCurrentOpenedChildPage].ToString() + "; window.top.parent.Refresh();</script>", false);
But it is refreshing the page with previous session values. But I need the latest.
I have to develope one page using tree view in my application,page can have one treeview which is bind from database,i did the binding procedure, now senario as like below...
Treeview have parent node as CourseName.....
Each course have more than one sujbect,so child node of course node have multiple child nodes....
Now each subject have more than one chapter,so child node of each subject node have multiple child nodes....
Now whenever user click on chapter node i have to display topics for selected chapter on grid.....
And if user treeview collapsed and user try to click on subject name than i have to display those chapters and expand those chapters for selected subject...but when user click on chapter than i have to bind topic grid for selected chapter using chapterid..
I have a treenode and when the user selects the root, it does a post back and collapes everything. What I want is the Parent node to do nothing when clicked.
View 2 RepliesI am working on a page where I am looking a relationship property of Treeview.
TreeView1.Nodes.Add Relative, Relationship, Key, Text, Image, SelectedImage
Can We set Relationship here like tvwNExt, tvWFirst like vb. I am unable to find in ASP.NET I have a requirement where I need to go through in loop and set the parent Node, once and then child node. But due to loop its add parent node value everytime.
I have a web page, I am adding treenode value from database. I need to check if any value is already added in node then childnode value should be added in the same parent node. In vb6.0 we have something Key of the node, but here I am unable to find. Here we get only text and Value for any Node.
View 2 RepliesI have this working in several pages in my site but in one page it wont work!
this is the hierarchyof the page.
I have a treeview in a div,in an asp:panel, in an updatepanel in a user control. the panel is shown/hidden using the ajax modalpopupextender.
this user control is placed in a content page (using a master page).
Now that you got the above, I'll let you know what ive tried already.
I tried doing this:(which works perfectly when the treeview is placed simply in an aspx page)
[Code]....
tried using also :
[Code]....
Basically i kept playing around with it trying different ways but seems like the selected node is just not visible even though i call this JS function after i have selected the Node in code behind.
Periodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.
