Passing Values between Controls

[ResolutionsNET]

Hi,

I need to pass/access varibles from two controls (see below) how do I do this?

<%@ Page Buffer=&quot;true&quot; Language=&quot;VB&quot; Explicit=&quot;true&quot; %>

<%@ Register TagPrefix=&quot;x&quot; TagName=&quot;1&quot; src=&quot;/inc/_1.ascx&quot; %>
<%@ Register TagPrefix=&quot;x&quot; TagName=&quot;2&quot; src=&quot;/inc/_2.ascx&quot; %>

<%@ import Namespace=&quot;System.IO&quot; %>

<x:1 id=&quot;first&quot; runat=&quot;server&quot; />
<x:2 id=&quot;second&quot; runat=&quot;server&quot; />


Thanks

Hey Winter,

All you have to do is write some &quot;wrapper&quot; functions in your user control

For instance, lets say that your user control has a textbox called TextBox1. If you wanted your page's codebehind to get that value, you'd write this function in your ascx:

Public Function GetTextBox1Value() as String
GetTextBoxValue = TextBox1.Text
End Function

So in your page, if you wanted that value, you just say:

UserControl.GetTextBoxValue()

Its very similar to the Get/Set idea in object code

If your gunna to get sets then just use the Property structure thingy

Public Property TextBox1Value() As String
Get
TextBox1Value = TextBox1.Text
End Get
Set(ByVal Value As String)
TextBox1.Text = Value
End Set
End Property


This way you can get/set the properties like you would a normal property
something = UserControl.TextBox1Value

UserControl.TextBox1Value = &quot;something&quot;

It is pretty much the same as Jacks with just a little more flexibility in it.

Oh sure, the guy passes me in the standings AND critiques my code.

I know its &quot;Anyhoo&quot; jealousy.



Good point about the properties though. It really is six of half a dozen (i think I said that right...my boss always says it anyway): if you want to only read from teh control, either will work, but the property would require more lines of code. If you want to be able to set and read though, Mark's code definately makes more sense.

Thanks guys, this is great stuff. It's already an option I've tried. What I have the problem with, is how do I access properties from x:1 whilst inside x:2.

Any ideas

Cheers

well, if all you want to do is get a property and pass it in, then you just set up the code we suggested in both. Then, when you want the value from uc1:textbox1 to go to uc2:textbox1 you would just go

uc1.TextBox1Value = uc2.TextBox1Value

If you need to have the usercontrols access the data in a different way, maybe you need to create another usercontrol that contains both of the usercontrols

Not according to my list; I'm in 3rd, you've got 2nd spot.

(er...not that I'm counting or anything, or focussing on the competitive nature of these forums...oh no)

Well I'll be...didn't even know that full list existed.

Mine must just be funky then, as Netangel is ahead of Alcar on mine.
