javascript does not have build-in date formatting. But, many people have wrote small js code to format date to various degree. Simple Google[^] search turns a wealth of examples.

Hi,
I am beginner in asp.net and my problem When i try to redirect with the code
Response.Redirect("~/Zone/Home.aspx?ZID=24&"); an exception is being raised i.e;
"Thread is being aborted" and after this redirection is done without any problems. What cud be the possible mistake made by me?
Plz help.

If you look at the Redirect[^] documentation, you will see it takes a second parameter of a type of bool to indicate if you want to terminate current page execution
use instead
Response.Redirect("~/Zone/Home.aspx?ZID=24&", false);
|
|
|
|
|
|
But, be aware that if you do set the value to false, the page you are currently on will continue to process. If the value is true (the default) then the page stops processing immediately.

That is interesting, but I am not sure how it will work though.
In my code I use expensively try/catch. Then I have have catch all basin at the application level. Any unhandled exception will end up at the catch basin. If you rethrow the ThreadAbortException doesn't it get bubbled up. Don't you want to eat that exception?

Yes, it will.
Yusuf wrote: Don't you want to eat that exception?
Nope. It is the exception that the Redirect method throws to force the end of execution. If you catch it and eat it execution resumes when you've already said you want it to stop so you can redirect elsewhere. (Although, I've been told that ASP.NET will automatically rethrow it if you catch it - which I didn't know before and wish to confirm before I change my stance as I don't see how it does it.)

I’m building a fairly typical ASP.NET web app that has a data entry screen, a number of maintenance screens, and some reports. The data entry screen and the maintenance screens all work in the same way; they use ListView controls embedded in UpdatePanels.
So far so good – they’re solid and reliable. However, performance is an issue for the data entry screen, and I don’t think using a ListView is going to be good enough. Using Fiddler, I can see that every postback sends 30Kb of data down the line, which seems a little excessive to me.
I’ve experimented with a ‘fast’ data entry screen. This one just uses a plain ol’ table, no UpdatePanels. I handle the click event on the client side by calling a web service that updates the database. This has got me from 30Kb down to 12 bytes!
The thing is, I’d like to retain use of the ListView if possible, because I want consistency with my other screens, and I’d like to continue to use the DataPager control. To do this, I’m obviously going to need to override the __doPostBack functions that the ListView generates.
My question is, is this going to be more trouble than it’s worth? Before I waste days of my life on this, is there a much better way of going about it?

Well, the reason you see big chunk of data (30k) being sent is because of control viewstate[^]. You can turn off the ListView viewstate, but you will loose all the controls viewstate functionality. Do you need to remember the control state between postbacks?
|

I'm planning to avoid postbacks and ViewState altogether, and just call webmethods from the client. I know I can easily do this without using a ListView at all, but I'd like to try it with the ListView so that I can keep using the DataPager (which only works with ListView).
So my plan is to just use the ListView like a Repeater to build my table, override the __doPostBack so that it does what I want (i.e. call a webmethod rather than do a postback), and hopefully still be able to use the DataPager.
I guess I'm just asking whether anyone else has tried that approach, or can suggest a better one, before I commit loads of time to it.

I'm not sure what you gain by getting rid of postbacks/viewstates. If you want to mimic the look and feel, then design your ListView then see the client side generated code. I don't have .net3.5 (which ListView is supported), but, I think, it will get rendered as table. Get the table layout and structure and use straight table with some css to achieve similar look and feeling.
If you want to override postback, then prepare to write some client side code to supplement. I know you mentioned you want to call webservices. Do you need to support sorting, pagination ....
In any case see here[^] and here[^] for one way of overriding postback function

Thanks Yusuf. The ListView is template-based, so will generate whatever you put in the template, but yes, that's usually tables.
Thinking about it, I guess the only thing I gain by keeping the ListView is easy pagination (the DataPager control). Maybe the easiest thing will be to just abandon ListView and write my own pager.
Thanks again.

The treeview control has an attribute called ShowCheckBoxes which contains the values as"All,Leaf, Parent, Root and None". Because of this, I cannot add the checkboxes both for Parent and Child.
Is there anyway that I can add the checkboxes both for parent and child? Please help.

Hi,
You have to write code like this,
Protected Sub TvwPages_SelectedNodeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TvwPages.SelectedNodeChanged
If TvwPages.SelectedNode.Text = "Screens" Then
If TvwPages.Nodes.Count > 1 Then
TvwPages.Nodes(1).Collapse() 'Collapse Reports
End If
TvwPages.Nodes(0).Expand() 'Expand Screens
ElseIf TvwPages.SelectedNode.Text = "Reports" Then
If TvwPages.Nodes.Count > 1 Then
TvwPages.Nodes(0).Collapse() 'Collapse Screens
End If
TvwPages.Nodes(1).Expand() 'Expand Reports
End If
End Sub
If you have more than one Tree View item,
Use this line ,( PUT in a For Loop) till List Count
TvwPages.Nodes(i).Collapse()

Hi
this is good for selecting child nodes. because "SelectedNodeChanged" event hires when child node is selected. But I want when Parent node is selected it should be expanded and if any expanded nodes are there they should be collapsed.
Plz help me

Hi,
Try Using this....
Protected Sub TvwPages_TreeNodeExpanded(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.TreeNodeEventArgs) Handles TvwPages.TreeNodeExpanded
If e.Node.Text = "Screens" And TvwPages.Nodes.Count > 1 Then
TvwPages.Nodes(1).Collapse()
End If
If e.Node.Text = "Reports" And TvwPages.Nodes.Count > 1 Then
TvwPages.Nodes(0).Collapse()
End If
End Sub
and..one thing...never say URGENT. It is completely irrelevent to others.
