You need to look for more detailed error messages. Cannot create folder is too generic.

Thanks for your response! Where can I find these detailed error messages? The output I posted is all it shows on my output window, and there are no error messages in my Error List.
Thanks again.

Masterpage + IFrame

Hi....

I have used masterpage and have iframe on it and set Src = "Rotator.aspx".
Now my masterpage and Rotator.aspx are on same directory (just under the root).

My rest of the pages uses this masterpage and they are under 'root/user/' directory.

Pages which are in the root directory will load iframe with "rotator.aspx" but pages which are in the 'root/user/' directory gives "page not found" in iframe.

so how would I set the src property properly..

thanx in advance.

Try setting the source property for the IFrame as Src = "~/Rotator.aspx"

Confused by the behaviour of static variable

Hello Guys

I've a datatable whose values need to be maintained across postbacks. (Just single page, not across multiple pages). This datatable is not read only. I mean to say some data can be changed based on user selection during partial postbacks and need to be maintained till the final submit. I declared the datatable as static and could retain the values across partial postbacks. But the problem is that I've always thought that in multiuser environment only one copy of the static variable is created and shared across the users. But my datatable behaves differently.

I opened the page in a browser and pressed Ctrl+N for new window. When I work on both windows, the datatable is not clashed. I mean - changes done in one window is not reflected in the other window. This is the behaviour I want exactly. One user's change should not affect other user. This is a reporting page and I store the user selections in the datatable before the final submit. Based on the options in the datatable, the report is created.

Though I achieve the desired functionality, I am worried whether what I am doing is right. Is it true that a static variable is shared acorss users or not??? Any inputs?
I am using VWD 2008 Express edition and c#.

By my understanding, it depends on the container that you use. If the static variable is contained in a instantiable class then the variable is not shared across users. If it is contained in a static class then it is shared across users. This is just my understanding and there is every possibility that I might be wrong.

A safer and a much cleaner approach to this problem would be to put the datatable in the page's viewstate. This way the datatable along with the changes is available as long as the page is alive and you get peace of mind!

HTH!

Hi everybody,

I´m trying to deal with a little problem using Certificates, I have a ASP.NET Website (VB) with the traditional User/Password login. Now I want use SmartCards attached to the Client-Machines. I saw few ASP.NET websites poping up some Windows Dialog for Certificate Selection (NOT a Windows Chalenge Login) it´s just a list of certificates inside the SmartCard CHIP.

Does anyone know how to ask for that Dialog using server side?

Problems while extending gridview [modified]

I am trying to extend the GridView. I am unable to find out the control placed in the template field and its binding. Is there a way to get to know that? For instance I add a template field as below in the gridview:

< asp:TemplateField>
< HeaderTemplate>
< asp:Label ID="lblHeader" runat="server" Text="TemplateColumn">
< /asp:Label>
< /HeaderTemplate>
< ItemTemplate>
< asp:Label ID="lblCol1" runat="server" Text='<%# Bind("col2") %>'>
< /asp:Label>
< /ItemTemplate>
< /asp:TemplateField>

Now, I need to identify
1. the template column from the column collection of the gridview
2. the datafield I use for binding.
3. the control I place inside the template field

Use the UpdateProgress control along with your UpdatePanel

Hi
"Sys.WebForms.PageRequestManager" class manages partial-page updates of server UpdatePanel controls in the browser. There are two events which handles before an request made and after completing the request in the browser. These are

1. Sys.WebForms.PageRequestManager beginRequest Event : Raised before processing of an asynchronous postback starts and the postback request is sent to the server.

2. Sys.WebForms.PageRequestManager endRequest Event: Raised after an asynchronous postback is finished and control has been returned to the browser.

You can simply use this events to show and hide your progress bar. See code below

<script type="text/javascript" language="javascript">
                        Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
                        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args)
{
    var elem = args.get_postBackElement();
    ActivateAlertDiv('visible', 'AlertDiv', elem.value + ' processing...');
}
function EndRequestHandler(sender, args)
{
   ActivateAlertDiv('hidden', 'AlertDiv', '');
}
function ActivateAlertDiv(visstring, elem, msg)
{
   var adiv = $get(elem);
   adiv.style.visibility = visstring;
   adiv.innerHTML = msg;                               
}
</script>

Cheers

I have populated a dropdown control.
The items inside the dropdown are: "hello", "you", "there"

based on a few retrieved items from the database, I would like the correct item in the dropdown to be selected.
For example:

string strValue = "you";

ddlgvSources.selectedItem.Text = strValue;

The problem here is that the text in strValue over writes the value inside the dropdown, so when I click on the dropdown to see all the items, it shows:

you
you
there

Do you know why?
Thanks

You are trying to replace the text instead of selecting the required one.
You have to find the correct list item using the method FindItemByText or FindItemByValue of DropDownand then Select it.

ListItem item;
ddl.SelectedIndex = -1;
item = ddl.Items.FindByText("hello");
if (item != null) item.Selected = true;

Try this:

ddlgvSources.SelectedValue = strValue;

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
