I 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.

I do try to use the modalpopup extender, it works with the client button click but not with the server side method.
I even used the document.readyState == "complete" javascript method to be shure the whole page is loaded.
But I'm still unable to get that modalpopup extender control.

i am using vs2008 for web page. i want to see my assembly name. For this i am right clicking on solution/project name but i am not able to see assemble name .
I am able to find the controls of all of these Lables and TextBoxes accept the edateTB. This is strange to me because it is in the same view as the sdateTB. So why would edateTB return NULL when I try to use FindControl on it and sdateTB return the correct control?
Here is the codebehind where I am getting this error. There is more code in this, but I just thought I would include everything up to the part where I get the NULL error.

I'm trying to load web resources from a linked assembly. Whatever I try, I get the exception:
Web resource 'MyNameSpace.scripts.jquery-min.js' was not found.
I'm using the following code to load it:
ScriptManager.RegisterClientScriptResource(this, typeof(MyNameSpace.SomeClass), "MyNameSpace.scripts.jquery-min.js");
What am I missing / doing wrong here, causing that exception?
My observations so far:
In the Reflector these resource is visible, and named as MyNameSpace.scripts.jquery-min.js In the AssemblyInfo.cs file of the project, the file is registered as:
[assembly: WebResource("scripts/jquery-min.js", "text/javascript")]
The file lives in the 'scripts' directory
On a sidenote, I've tried using Page.ClientScript.GetWebResourceUrl() but this generates an URL without checking if the resource exists. It also seems WebResource.axd is not mapped in Web.config at all.

But. Not all the dlls are getting updated. some dlls are getting updated to 3.5.0.0 but some remain in older version 2.0.0.0. Also, i could not find some dlls in 3.5.0.0 folder
For example the following dlls are there in 2.0.0.0 but not in 3.5.0.0

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.
I'm trying to define the parameters of my data source using a stored procedure. My Stored Procedure Syntax is perfect and i'm happy with that, i've just got trouble with connecting my parameters to my controls. I have 19 Parameters, of which i've managed to connect 17 to controls within my ASP.Net form (some to text boxes, some to ddls etc...)
However, i'm trying to connect a particular parameter to a control, but when i drop down my list of controls it's not visible? The control is within a hidden panel so i've un-hidden it and it's still not there. I've even commented out the panel and tried that but i can't find this control! I just cant seem to get this control to appear in the list.
Has any one seen anything like this before at all?
