Declare a public property in the user control and set it from the page.
Example:
User control
Public Property ChangeName() As String
Get
return custName.text
End Get
Set (byval value as String)
custName.Text = value
End Set
End Property
In the page:
Protected WithEvents uc as Usercontrol
uc.ChangeName = "new name"
If you have any questions reply to the post.

codeasp Thank you codeasp for your reply,But I have class name userinfo and Declare a public property:
Private _members_no As Integer = 0
Public Property members_no() As IntegerGet
Return _members_no
End Get
Set(ByVal Value As Integer)
_members_no = Value
End Set
End Property
in the page i Change the Property members_no
Protected userinfo As New userinfo
private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Inituserinfo.members_no=1
End Suband I have usercontrols the class name in header,When i load the usercontrols in page the value returned is 0 not 1.
how When i change the value in the class userinfo by page,make the usercontrols get the value changed in class userinfo when load the usercontrols in the page.

Now its is a matter of cloning those forms for various uses and modifying or adding code to suit the particular need. Copy and paste works OK, but there is a lot of changing of certain words, etc. Is there a way in ASP.NET to take these basic forms, turn them into classes or templates, create forms from them, then add or overwrite code? ?

Single page with multiple user web controls VS Multiple page with specific user web controls
I have a question regarding single page with multiple user web controls vs multiple page with specific user web controls Option 1: I am of the opinion to have multiple pages with specific user web controls and use an object to store all the information as the user navigates through the application. And finally at the end, read this object and save all the information to the backend database. Option 2: My respected team member suggests that we have only one page, with all the specific user web controls and not use an object, instead show/hide the user web controls based ...
Solution for web forms that look just like paper forms ? User controls ? Adobe fillable forms ?
I am looking at ways to web-enable a series of company forms that need to have the form itself look just like the paper version. It would be great if I could use an image of the form itself as a background, and then draw the UI components on top of this. Then there is the question of printing these forms complete with the data that was filled in. What are some options for doing this kind of application ? Im open to 3rd party solutions as well. Our company currently has a desktop application which does this, but I want to come up with a web based solu...
