pass the value in a textbox from form1 to the textbox in form3.

When the button on Form1 is clicked, pass the textbox's value to Form2 through Form2's constructor.

I know how to pass the value to Form2,which is directly called by Form1.
But i want to know how to pass value to Form3 which is not directly called by Form1.Form3 is called by Form2,and Form2 does not uses the value that is required by Form3(the value which is passed from form1 to form3).

Form1 has a button which on a click opens Form2 and Form2 also has a button which on click opens Form3.I want to pass the value in a textbox in Form1 to the textbox in Form3.The main problem is that Form3 is not directly called by Form1 in this case i want to know how to pass the values b/w these forms.
hope now my ques is clear.plzz give the solution.

hi,

The answer is already given by r035198x .

You pass the value from form1 to form2 and from form2 to form3.

Send the value through the form2s constructor and store the value in some global variable in form2 and when u call form3 send it to this constructor and thats done you got the value in form3.

Pass the value of textbox in the constructor while calling form2. store the value in a global variable inside form2, eventhough it is not used, and pass the value on form3 when calling it by using that variable as parameter for the constructor.

thanks its working.

Welcome. Reading a tutorial on how to use classes in C# will clarify further.

A static class is a nice way to do this.

i.e. - information.cs

then a public variable in there

get:{}
set:{}

methods for that value.

then when you call form 3 look for Information.myValue;

If the variable is not required to be an instance variable by the design then that would also work. Many instance variables have made been made static incorrectly just to get at them as quickly as possible when writing code though.

in VB couldnt you just do something like





and then in form3 just use



wouldnt that work ?

Only if the variable isn't changed before being requested. It should really be passed along through the stack if it can be.
