i have textbox and button in form one and grid on second form,when clicked on button the information given in textbox should be stored in database, second form grid should be updated in C#
How to pass data from text box in one form to the datagrid in other form

A couple ways I can think of right now:

0) Make the button a public variable so the other form can hook the Click event. When the click event is sent, the control that sent the event is represented by the sender parameter.

1) Create a public custom event that fires when the button is clicked and have the form with the grid monitor the other form for that event. You're going to need a custom EventArgs object to contain the text from text box.

I'd probably go with item 1 (as opposed to item 0).

is there any sample code which i can follow

1. Data Binding (Google it)
2. Your second form polls the database for changes every few seconds (or whenever)
3. You have a static class that provides events to all forms to identify if data in another form has been changed
4. Form1 sends a message to Form2 to say that is has updated some data

Which one tempts you?

Based on comment...

So in the Button event in form1 just call the load data function is form2

   //save textbox value to database

You need to provide a variable in Form1 called form2 that is the instance of (or reference to) Form2

Which form opens Form2? is it Form1?

Added more: so form2 should have a load data method which I guess you already have. Make sure this isbpublic. Then in form1 you store a class level reference to your form2. then when you click button You fleck if the reference to form2 is not null and not disposed. Then you call the load method in form2. Like form2.LoadData();

....sorry my nexus one not so good for doing code. Will update I'm morning when on PC

So some sample code to illustrate...

public class Form1{
   Form2 form2;

   void OpenForm2(){
      form2 = new Form2();

   void Button1_Click(object sender, EventArgs e){
      //Save the textbox values to the database

      if(form2 != null && !form2.IsDisposed)

public class Form2{
   public void LoadData(){
      //This function loads you data grid data

...hope that helps
