Hi

I just have a quick databinding question. I have 2 forms.....
Form1 is my main form containing all the controls i want to bind the results of my query to
Form2 contains a datagrid containing a list of guests in the database. The user can click on a row to select a guest. They then hit the OK button. This will then run a query to retrieve that guests details from my database (this woks fine). What i now want to do is bind the results of the query that is run from Form2 to the controls (textboxes) on Form1.

Does anyone know how to do this?
I know how to bind to controls on the same form but not when they are on a differnt form!!

This is what i normally use...
Me.txtFName.DataBindings.Add(New Binding("Text", ds.Tables("Guest"), "F_Name")

in VB6 i would just replace 'Me' with the name of the other form, but this does not seem to work in VB.NET!!!
i.e
Form1.txtFName.DataBindings.Add(New Binding("Text", ds.Tables("Guest"), "F_Name")

when i try the above i get the following error
Reference to a non shared member requires an onject refernc

Can anyone please help me
Many thx
 
Hi
If form one is the caller of form two . I.e. you create and open from2
somewhere inside form1. Then form1 has a reference to form2 but not the
opposite. One way to over come that is to pass a reference to the object
that you want to bind in form1 to the constructor of form2. you have to
write new constructor for form2 that take a textbox( textboxes) . on form1
while creating form2 pass reference to the textboxes that will be binded
from form one .
So you will do something like this
Form2 theotherform = new Form2 ( this.whatevertextbox , ……)
Then in form two save these references in some object just to bind later.
This is not a good solution whoever since this will cause a circular
reference which means bad design
Why don't you send the query result to form1 some way, then you can do the
binding from there.
hope that helps,
