Getting value from one form to another in Windows Forms

[Guest]

Hi,

I have 3 forms in my application. Form1 which is a MDI form calling Form2 & Form3. Form2 has a textbox "TextBox1" and Form3 has a CommandButton "Button1".

I will show both Form1 & Form2 as MDI Child from Form1. Now when i click on the Button1 in Form3, I want to access the TextBox1 value of Form2.

How to achieve this... in VB6 is was very simple as I can use Form2.TextBox1 but how in VB.Net or C#

Thanks...

Hi Pradeel,

Have a look at the me.parentform from your form.

http://msdn.microsoft.com/library/d...formscontainercontrolclassparentformtopic.asp

When you have that, you can again get the childforms of that form.

I hope this help?

Hi,

In this case my MDI form is not doing anything other than just calling the Form2 & Form3.

I need to get the data of Form2 from Form3 where both are MDI Childs.

Thanks

Hi PradeepKel,

As I asked before did you try it, by instance this in form3?
\\\\
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
For Each frm As Form In _
Me.ParentForm.MdiChildren()
If frm.Name = "Form2" Then
TextBox1.Text = DirectCast(frm, Form2).TextBox1.Text
End If
Next
End Sub
///

I hope this fullfils your needs, I tested it and it did go.
(You can of course as well create a shared property to use, however this is
a direct anwer in my opinion on your question)
