I have a tree view created in my HTML Page
[code]...
now i want to hide the Stats node in the page load function in my code behind....
i have a asp.net tree view control and its being data bound to XML returned from the DB.
once bound and the nodes are present in the control how can i remove/ hide the root node?
I'm building a custom web control with a public property which I only want to be available in design time (i.e. make it unavailable in code behind). The DesignOnly attribute promises to do just that, but when I set [DesignOnly(true)] it has no noticeable effect whatsoever:
[Bindable(true)]
[Category("Appearance")]
[DefaultValue(null)]
[Localizable(false)]
[DesignOnly(true)]
public string MyProp
{
get
{
return ViewState["MyProp"] as string;
}
set
{
ViewState["MyProp"] = value;
}
}
The property still appears in code behind IntelliSense. Setting a value to it in code behind works. In these respects, the behavior is just as if the attribute had never been set. And I've cleaned and rebuilt the complete solution. Twice.
i have asp.net 2.0. I want to open a context menu when i RIGHT CLICK my tree view node. context menu has options...Delete Node, Add Node.

View 3 RepliesI am binding a treeview with XmlDataSource. On my login page I want to hide some node like
see my login code
if (Session["uname"] != null)
{
if ((Session["uname"]).ToString() != "")
{
if ((Session["UserType"]).ToString() == "Administrator")
{ dont hide nodes }
else { hide some nodes}
}
else
{
Response.Redirect("index.aspx");
Session["uname"] = "";
}
}
else
{
Response.Redirect("index.aspx");
Session["uname"] = "";
}
}
so how to do that, if you need my .aspx code for treeview so free to ask.
Problem for me is that a tag is being generated that apparently just moves the treview a little bit. So I am thinking I should delete it at runtime. How do I do that?
Code:
<a href="#MainContent_TreeView2_SkipLink">
<img height="0" width="0" style="border-width:0px;" src="/.../WebResource.axd?d=2Lx-Wo-AmOSQUgrfkZW7jw2&t=634209174377343750" alt="Skip Navigation Links.">
</a>
Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?

I have a bunch of divs that are widgets. I am using a custom role provider and I need to hide the divs based on roles. Is it better to add a "runat=server" attribute to the div so that I can hide/unhide in the code behind? Should I hide/unhide on the aspx page or do i use panel controls and hide/unhide in the code behind?
View 1 RepliesPeriodically 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.

View 1 RepliesI have a clean installation of Windows 7 with VS2010 RTM and am trying to get the ASP.NET Development Server to work. When I run the project, the WebDev server starts and shows that it's listening on port x on localhost. I've tried:telnet to the port. The port is not listening. running netstat -o shows that the WebDev server is in fact not listening on any port. manually changing the WebDev port to a different port and restarted VS without effect. I have Windows Firewall turned off entirely and am not running any other firewall software either.

Has anyone does this before.
I want this functionality both in C# and JavaScript.
In javascript I was trying the following
var dte = new Date();
dte = Date.Parse('May 20 2010 2:54PM')
however this was giving me NaN.
