function DisableButton()
{
document.getElementById('ExcelExportButton').disabled =true;
}
This code works fine with me, my button's id is ExcelExportButton
|
|
|
|
|
also look at this, what I am using for button in some of my pages, change the attributes accordingly and this should work fine with a combo box as well
Me.LoginButton.Attributes.Add("onclick", GetPostBackEventReference(Me.LoginButton) & ";this.value='Please wait..';this.disabled = true;")

It's working just fine. Setting the disabled property to false makes it not disabled. If you want it disabled you should set the property to true.
The style.visibility property is not a boolean. Why don't you just look up some documentation[^] instead of guessing how to use things?

First of all, is this in your main page or in a js file ? If the latter, then the <%= will not be changed to be the Id
beyond that, like Guffa said, it's better to read some docs than to make random guesses, but disabled = false plainly will enable to control.

Is there a dropdownlist control which the ID is 'DropDownList'? If no, you should replace 'DropDownList' to the correct ID of the dropdownlist control which you want to disabled.
document.getElementById('<%=Label10.ClientID%>').style.visibility = false;
It should change into below:
document.getElementById('<%=Label10.ClientID%>').style.visibility = 'hidden';

I'm getting the following error trying to debug (F5) a web application on my Vista Machine. What could be the cause?
Unable to start debugging on the web server. Could not start ASP.NET or ATL Server debugging.
Verify that ASP.NET or ATL Server is correctly installed on the server.
I'm quite pressed for time so would appreciate suggestions if anyone has already been through this, before I invest time going through it.
Thanks in advance.

You can also try doing the view in browser option then Debug -> Attach to Process and pick WebDev.WebServer.EXE and see if that works.

Another test application runs OK using the built in VS2005 web server.

Hi all
Here is the situation, I have a button named "Export To Excel", Now when someone clicks the button the button gets disabled as I added the following code to Page_Load
Me.ExcelExportButton.Attributes.Add("onclick", GetPostBackEventReference(Me.ExcelExportButton) & ";this.value='Please wait...';this.disabled = true;")
Now I execute some code for generating the excel file, at the end of the event I use the following statements to open a "Save As" dialog box so the use can save it,
Response.ContentType = "application/excel"
Response.AppendHeader("Content-Disposition", "attachment; filename=Report " + System.DateTime.Now.ToString.Replace("/", "-").Replace(":", ".") + ".xls")
Response.TransmitFile(fileName)
Response.End()
It all works fine but the disabled button does not enable back whatever I do, the only way I think I can enable the button is to redirect the page to itself,
But if I use Response.Redirect next to Response.End the page redirects but the "Save As" dialog does not appear and so the user can not save the file,
any help would be really appreciated,
Thanks in advance

You can only send one response back to the browser. You can't both send back an Excel document and a page.
If you want to do both, you have to send two requests from the browser, one that gets the Excel document and opens in a different window, and one that gets the new page.

Thanks, I think I got it.

That would be:
Button1.Attributes.Add("onclick", "window.close();");
The javascript: protocol is only used when you put Javascript code in an URL. If you do that anywhere else, it becomes a label instead.
Naming the attribute OnClick only works in html. Using onclick works both in html and xhtml.

Alt + F4?
Javascript :
function CloseMyWindow()<br />
{<br />
window.close();<br />
}<br />
but if you didn't open the window then you will get a client side message box asking if the user want to allow you to close it.

you can add a parameter to the close function.
window.close(opener=0);
This will remove the message.
