Hi,
I have placed a usercontrol inside a .aspx page.
The usercontrol has a label control called label1.

Question:
In the webform.cs, how do I get the value of the label control in the usercontrol?
Thanks

You just use the following code

Dim str as String
str=ctype(usercontrolname.findcontrol("lable1"),lable).Text

Create a property in user control & access its value in .aspx page.

in User control,

public string TextValue
{
  get{ return label1.Text; }
}

On .aspx page, you can get the label text as:

string labelText = Userconrol1.TextValue;

As Arun said,having public property is a better and maintainable approach.

I do not seem to be able to access the usercontrol from the .aspx cs file.
Note that the usercontrol1 is inside a folder called usercontrols.
Any thoughts please?
Thanks

Did you register the user control on the aspx page?If not First register it on your aspx page.
else just go to design view of your aspx page and drag the usercontrol on your page it automatically register the control.Then you will be able to access the control from your aspx page.

Cheers!!

As I think, the best way to disable the back button is "don't create the history of the page". Because may be in some browser's, disable code will not work.

Here is the code to remove the history of a particular page:-

<%
Response.Expires = 0
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1)
Response.AddHeader("cache-control", "private")
Response.CacheControl = "no-cache"
%>

Hope this will help you......

Thnks For Reply

I have used this code

but it is going to back......

in all browsers(IE,Mozila)

Re: How to Disable back button

This code has to be used on previous page.

Means, if you want's to disable the "back" button of page "zxc.aspx", so you have to put this code in previous page of "zxc.aspx", from which you have come to "zxc.aspx". i.e. if you have come from "test.aspx" (on click of any link) to "zxc.aspx", then you have to put this code on "test.aspx" page.

Try this. This will definitely work in all browsers.
