Web Forms :: Treenode Attributes - How To Access
Mar 17, 2010
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.

given that I can add various addributes to the stock membership provider I assume I can do the same with my own provider implementation.
<add name="MyMembershipProvider" type="Portal.Infrastructure.MyMembershipProvider"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
[...] />
My question now: How do I access these values in the code? I understand that the ConfigurationManager can be used to access key value pairs in the appSettings section but this is different.

Im trying to create a "user control menu" where links to a page's usercontrols are placed at the top of the page. This will allow me to put several usercontrols on a page and allow the user to jump to that section of the page without scrolling so much. In order to do this, I put each usercontrol in a folder (usercontrols) and gave each control a Description property (<%@ Control Language="C#" Description = "Vehicles" .... %>).
My question is how can I access this description dynamically? I want to use this description as the link in my menu. So far, I have a foreach on my page that looks in the ControlCollection for a control that is of the ASP.usercontrols type. If it is I would assume that I could access its attributes and grab that description property. How can I do this? (Im also open to a better way to achieve my "user control menu", but maybe thats another question.) Should I use ((System.Web.UI.UserControl)mydynamiccontrol).Attributes.Keys?

So I've eagerly added the System.ComponentModel.DataAnnotations namespace to my model.
I've added things such as:
[Required] [DisplayName("First Name")]
public string first_name {get;set;}
I really like these attributes because they save me from having to write custom T4 and/or modify views heavily. This way, I can regenerate a view confident that it will add the display names I want, etc.
The problem comes in when I started building a DataGrid helper inspired by the one in ASP.NET MVC2 unleashed. In this helper, Stephen uses reflection to get at the column headings.
var value=typeOf(T).GetProperty(columnName).GetValue(item,null) ?? String.Empty;
Well, the trouble is I don't want to retrieve the property name. I want to retrieve the value for the DisplayName attribute.
My first attempt at this was to look inside the Attributes property of the PropertyInfo class. Unfortunately, none of the data annotations show up as an attribute.
Is there a way to retrieve the data annotations using reflection?

I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:
[Required(ErrorMessage = "Please enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Password", Description = "Your secreet password")]
public string Password { get; set; }
All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:
<%: Html.DescriptionFor(m => m.Password) %>
should produce following html: <span>Your secreet password</span>

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?

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 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.

I 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.

Is there a way to check/uncheck the checkbox in a tree node by just clicking on the treenode text. I tried something like this - I can check the right checkbox when I click on the node text but I am unable to uncheck it. Is there a way to do that.
protected void tv_SelectedNodeChanged(object sender, EventArgs e)
{
TreeNode tn = tv.SelectedNode;
tn.Checked = true;
this.tv.SelectedNode.Selected = false;
}
