Hey again!

This time I want to request the .Text value of a textbox on a page. But I want this to be done from a central module.

So I've got a textbox (txtBox1) and I want to request that value from a global module (Auth), in such a way that I don't have to submit any data to the function by using the header ( Function Test(ByVal text As String).

Is there anyway of doing this? I can submit the page to the function by using

Public Function Test(ByVal Page As Page)

But howto get the data (txtBox1.Text) from that page?

Can't you just put

Protected Text1 As System.Web.UI.WebControls.Textbox

Then use Text1.Text like normal?

Where? In the module? In the page it already says that. But I don't know if it will work.. I'll give it a shot.

Protected stuff can't be used in a module

Nop that method won't work. "Object refference not set to an instance of an object"... The most annoying error of all.

Maybe it has something todo with Page.FindControls or something like that.

I guess I'm almost there

Public Sub Test(WichPage As Page)

 HttpContext.Current.Response.Write(WichPage.FindControl("txt Box1"))
End Sub

Returns "System.Web.UI.WebControls.Textbox"

Now I just need to figure out how to set the .Text value... I'm quite sure it is possible.

Got it!!! Jeeej. The WichPage still needs to be set from the page, but that's better than before. The topic was quite useless, but it might be usefull to people who want the same?



Public Sub Test(ByVal WichPage As Page)

Dim TestBox As System.Web.UI.WebControls.TextBox

TestBox = WichPage.FindControl("txtBox1")
TestBox.Text = "Boe"
End Sub
