Hi,
Have a look at Server.Transfer vs Response.Redirect[^] for your clarification.
In Brief:
Response.Redirect simply tells the browser to visit another page. Server.Transfer helps reduce server requests, keeps the URL the same and allows you to transfer the query string and form variables.
Regards,
Jay

Dear All,
I'm a beginner in ASP.Net and was building a asp.net application. Just wanna to ask is there any commands or functions in asp.net which can act similiarly like Application.DoEvents in windows programming? Please help. Thanks!

You can use client scripts i.e., java script to execute the applications by using var wshShell = new ActiveXObject("WScript.Shell"); object.

Actually my web application is link to a scanner where tags/bar code goes over the scanner, the tag number will be display in a listbox. There are a DO loop in the program checking whether any tags had been scanned. If yes, the program will display the tag in a listbox. Else the program will continue to loop till the user press stop scan.
At first i thought in web application, there is functions such as Application.DoEvents which will process the event once it detect user input. Any idea on how to display tag numbers which were scanned and display it in the list box on shot without refresh the page? Please help. Thanks alot.

You can use a client control or server control with client script to achieve this by using AJAX

Dear Sathik,
Thanks for your reply. I try using AJAX in my application but i face another problem. Is it anyway for me to execute some functions under the button.click event before calling the client script functions using Ajax? Thansk in advance.

How would I delete a file from the server? I haven't been able to find any code that demonstrates this...
AHA! File.Delete 
|
|
|
|
|
Give this a shot:
System.IO.File.Delete(Server.MapPath("filetodelete.ext"));
- S
50 cups of coffee and you know it's on!
|
|
|
|
|
try this
using System.IO;
path = Server.MapPath("../Client").ToString();
File.Delete(path);

I have master page with several panels and depending on the user configuration I load the childpages on different panels, in other words I move around the ContentPlaceHolder, now, since I started doing that some server controls started to behave strangely, for example a gridview which was working fine now when a row is selected it will say:
============================================================
SelectedDataKey null System.Web.UI.WebControls.DataKey
SelectedIndex 4 int
SelectedRow {System.Web.UI.WebControls.GridViewRow} ...
SelectedRowStyle {System.Web.UI.WebControls.TableItemStyle} ...
SelectedValue null object
============================================================
the SelectedDataKey and SelectedValue are null while SelectedRow is fine.
What happens when I add the ContentPlaceHolder to another panel that is not the original panel that contained it that makes this viewstate issue happen?
I switch the ContentPlaceHolder from panel to panel like this:
=========
PanelX.Controls.Add(mainplaceholder);
or
PanelY.Controls.Add(mainplaceholder);
=========
I'm doing this on "protected override void OnInit(EventArgs e)" of my "main.default.cs".
any help is very much appreciated!

Hi there. I'm sure that is in fact where a viewState issue would come in. The Panel is an INamingContainer, and child controls within a Panel would be rendered with client ID's that reflect the parent naming container.
I'm not sure I have any advice for you on what to do.
|
|
|
|

that makes sense however! I executed the page with the contentplaceholder on the default place and compared the html source with different panel positions and the placeholder has always the same id, every other property is identical.

I want to add a cancellation-confirm message to the cancel button a wizard control. I'd normally do something this if I could access the button control:
btnMyButton.Attributes.Add("onClick", "javascript:return confirm('Are you sure you want to delete the Internet?')")
Any ideas on how I can access the cancel button in the wizard control to do this? Thanks

Right click the Wizard component -> "Edit Template" -> "Finish Navigation Template" and create your own button set or whatever you want to put there.
sample template:
<FinishNavigationTemplate>
<asp:Panel BackColor="#E0E0E0" Width="300" Style="padding:3px" Runat="Server">
<asp:Button id="FinishPreviousButton" CommandName="MovePrevious" Text="Prev" Width="60" Runat="Server"/>
<asp:Button id="FinishButton" CommandName="MoveFinish" Text="Finish" Width="60" Runat="Server"/>
</asp:Panel>
</FinishNavigationTemplate>

hi! I have a user control, which consists of a label and a text box. I want to make validation of my user control with standard asp.net validators. I write the following:
[System.Web.UI.ValidationPropertyAttribute("TextBoxValidation")]
public class MyUserControl : System.Web.UI.UserControl
{
public string TextBoxValidation
{
get {}
set {}
}
The question is:
What should be written in the TextBoxValidation setter and getter?
Thanks in advance!

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
