Iam using livecontrols, but a sometimes the browser put this message..
The server viewstate cache has timed out..

I have the following DataList
<div style="overflow:scroll;">
<asp:DataList ID="dlAvatar" runat="server" DataKeyField="FileName" RepeatLayout="Flow" RepeatDirection="Horizontal" SelectedItemStyle-BorderStyle="Inset" >
<ItemTemplate>
<asp:ImageButton ID="imgAvatarSelect" runat="server" OnCommand="Buttons_CommandEvent" ImageUrl='<%# Eval("FileName") %>' CommandArgument='<%# Eval("FileName") %>' CommandName="Select"/>
</ItemTemplate>
</asp:DataList>
</div>
When I use Inline for the "CommandArgument" My onCommand event wont get fired, but when I take it out it works fine.
I I found the control like this inside my code behind:
//void dlAvatar_ItemCreated(object sender, DataListItemEventArgs e)
//{
// int i = 0;
// object a = e.Item.FindControl("imgChoose");
// ImageButton a2 = a as ImageButton;
// if (a2 != null)
// {
// a2.CommandArgument = ((AvatarPicture)e.Item.DataItem).FileName;
// }
//}
but, it finds the control and sets the value. but the commandArgument never changes its value.
And yes, its commented out because it wasnt working.
Any ideas?

+ Are you sure you want to use the imgChoose or imgAvatarSelect id?
+ Here, you are trying to set the CommandArgument property of the imagebutton in both the ItemCreated handler and the data binding expression. And you may already know that the ItemCreated event happens before the data DataBound event where the binding expression is normally executed. So if you want to use the ItemCreated event, you should not use the data binding expression, otherwise the CommandArgument property will be reset.

I tried at just usiing the data binding expression. And it wont fire. But if I delete the CommandArgument it doesn't fire. ( OnCommand event )
Maybe I should create the the DataBind event, that might be a work around.
I did the ItemCreated out of desparation.

Normally, you only need to use the data binding expression to simply set the CommandArgument property of the ImageButton. Have you tried using the ItemCommand event of the DataList control and see if it is fired? Have you viewed the page source and checked the id/name of the imagebutton?

Ok so I changed the Created to be like this:
void dlAvatar_ItemCreated(object sender, DataListItemEventArgs e)
{
int i = 0;
object a = e.Item.FindControl("imgChoose");
ImageButton a2 = a as ImageButton;
if (a2 != null)
{
//a2.CommandArgument = ((AvatarPicture)e.Item.DataItem).FileName;
a2.Command += new CommandEventHandler(Buttons_CommandEvent);
a2.Click += new ImageClickEventHandler(btnAdd_Click);
}
}
it find the control fine. and I add the handlers fine. no errors. But the Image is never posting back. This is just unreal. Is there a property that has to be set to allow posting back?
I'm caught in a nightmare
And to add. I put a regular button on the form and its not posting back.
This page belong to a master page. Do you have any idea why a page wont post back?

Thanks for helping min.
The reason was, my master page was set to "get". I changed it from "get" to "post" and it works fine.
I guess I had a brain fart.
thanks,
Nick

Hi!
I have created a new web site on IIS 6.0 running on Windows server 2003 std edition.
When i go to the IIS console and browse my web site , it displays an error message as follows:
"You are not authorsed to view this page".
You might not have the permission to view this directory or page using the credentials you supplied.
Can anyone help?
Thanks.
happy coding!

If you have the web site in a directory outside of the wwwroot, the aspnet worker account will require read access to that folder.

I get this sometimes, when I don't specify a page in the url and don't have an appropriate "default" page.
If I navigate to an actual page, then all is good, and if I add the non-standardly named page as a default document, then all gravy....
Could this be the issue in your case?

it is because of default page.
the code write in web.config
when not any page like "default.aspx" then it will give error.
so u should create page like default.aspx or redirect the page by writting response.write("anyfile.aspx")

Hi all
I have created a asp.net project under visual studio .net 2 and it all works fine. However when I upload it to my server it will not run because it is not a virtual directory that it resides in. Is there any way to make it so that I don’t have to use virtual directories and some how get it to work out where my dll’s are? Iv been looking at the config file to see if there is any way I can hard code where to point to the bin folder but as of yet I have not had much luck.
Any help would be grate.
Thx Scott.

Why can you not just make it a virtual directory?

I do not have the option to create them with the web host I am with. I know that you don't need them if you don't use code behind but it rather not have to go through all my code and stick it into the same file.

New web host maybe

As long as MasterPage and WebForm are in the same directory the JavaScript file works but when the directories are different I get javascript error cuz the file was not found.
I tried to google this problem and found that if you put the script block within the < HEAD >, ASP.NET 2.0 runtime will resolve the URL but for some odd reason that is not the case here.
Here is how I am doing it:
the file is inside a folder called JavaScript which is right under root folder.
I tried this first:
<head>
<script src="/Javascript/x.js" type="text/javascript"></script>
</head>
Then I tried this:
<head>
<script src="x.js" type="text/javascript"></script>
</head>
Then I tried this, but I got an ugly error:
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
<head>
<script src=<%= ResolveClientUrl("x.js") %> type="text/javascript"></script>
</head>
Can someone tell me how to take care of this problem . Thanks in advance.

Hi,
Try below code,
<script src="../Javascript/x.js" type="text/javascript"></script>
Hope it works...

Thanks for the reply, but
<script src="../Javascript/x.js" type="text/javascript"></script>
does not work.

Check if the framework resolves this:
<script src="~/Javascript/x.js" type="text/javascript"></script>

I have the following DataList
<div style="overflow:scroll;">
<asp:DataList ID="dlAvatar" runat="server" DataKeyField="FileName" RepeatLayout="Flow" RepeatDirection="Horizontal" SelectedItemStyle-BorderStyle="Inset" >
<ItemTemplate>
<asp:ImageButton ID="imgAvatarSelect" runat="server" OnCommand="Buttons_CommandEvent" ImageUrl='<%# Eval("FileName") %>' CommandArgument='<%# Eval("FileName") %>' CommandName="Select"/>
</ItemTemplate>
</asp:DataList>
</div>
I had it working in the file "ViewUser.aspx". Then I moved it to a page called "ChooseAvatar.aspx". It was working there too. Then, I moved it back to "ViewUser.aspx". And now it doesn't work.
It doesn't fire my event which is defined as so.
public void Buttons_CommandEvent(object sender, CommandEventArgs e)
{
int i = 0;
User user = Session["user"] as User;
if (user != null)
{
user.Avatar = Convert.ToString(e.CommandArgument);
user.Update();
if (user != null)
imgAvatar.ImageUrl = user.Avatar;
}
}
Is there some option is VS2005 IDE to get it to re-sync my page? Any ideas?
