Automatic templates for new items created in Visual Studio?

Is there a way (I think there is) to auto-generate a template for new items of a certain type created in a certain directory?

For example, if I create a class in a DAL directory, can I configure the VS solution to automatically create a template class with the required namespaces and variables that are used as a default for DAL items?

Accessing web controls in a page from javascript code

Hey guys, how's it going?

I got an ASP .NET web page with some radio buttons. Each radio button has a web control next to it (text box or drop down list), and I want to make the selection of the appropriate radio button to enable the web control next to it and disable all others.

Since there's no reason for this logic to happen on the server, I want to do this using javascript code on the client side. However, when I try to access the web controls in the javascript code on the page I get a runtime exception telling me the control is not yet created.

Anyone knows what could be a simple solution to my problem?

Thanks in advance,
Lior

Posting your code is a good start. I've never seen that error. Are you sure you're using the right client side ids to look for the controls ?

TreeNodeWithInfo

Hello everyone ,
I have a treeview with special nodes (i wanted to store extra information in them) inheriting TreeNode

public class TreeNodeWithInfo : TreeNode
{.....
}

When i add chils , i do it like this :

TreeNodeWithInfo tnGroup = new TreeNodeWithInfo("sdkh", 1);
       TreeView1.Nodes.Add(tnGroup);
      ...

But after a button click , when i try to acces the extra information by downcasting ,

protected void Run_Click(object sender, EventArgs e)
    {
    ...
    ManageTree((TreeNodeWithInfo) TreeView1.Nodes[0]);
     ...
     }
i get a invalid cast exception . The TreeView1.Nodes[0] still has the right information (the one correspongind to the base class , the TreeNode ) but it seems that it's not an instance of TreeNodeWithInfo anymore ..
if i do this in  Run_Click 
<pre>  Response.Write(TreeView1.Nodes[0] is  TreeNodeWithInfo);

i get a "False" . but if i do the same thing in Page_Load , i get True ...

Can anyone help me out ?

Thank You !

hi, What i understand is TreeView takes TreeNode as a Child.
So if you inherit TreeNode to some other object say TreeNodeWithInfo
and add it TreeView will not take extra Property you set.
Also when you access node from TreeView it will
set the node as TreeNode not TreeNodeWithInfo i.e. TreeView cast node
as TreeNode not you New Inharit Node.
So the bottom Line is I think your logic will not work.
Sorry If i m not right.

Thanks

Thank you for you answer !
But i think it actually has to do with inheritance , because in the page_load , after i set the nodes as TreeNodeWithInfo , it recognises it as a TreeNodeWithInfo , but at postback it becomes just a TreeNode .
I'm kinda lost Smile | :)

May be you are right!!
When You Bind this Tree? In Page Load?
As When You accessing The TreeView You will Get a Object as TreeNode.
I am Bit Confuse too. Sniff | :^)

Have you also created TreeNodeCollectionWithInfo and TreeViewWithInfo?
Because TreeView is still using TreeNodeCollection which uses the old TreeNode. And that's probably the reason for the invalid cast exception

Well , i haven't created a TreeNodeCollection .. But in Page_Load , the inheritance works perfectly . Weird stuff . Anyhow , i've managed to store the information in treenode.Value and i've given up on the TreeNodeWithInfo .
Thank you anyhow , guys !
Best luck !

You can't do that, Excel isn't a relational datasource.
You can delete values in fields (cells).
But you can't delete an entire record at once.
