passing data through forms

Dante Molfese

Hi!

I have a problem i hope someone can help me with:

I have a dgv which datasource is a dataset. these are in the MainForm

I have another form (form2) in which the user chooses the index of row to delete and accepts, closing the form2

so... how can i get that value in the Main once the form2 is closed. so that i can delete the row from the dataset?

Any Help will be appreciated! ;)

Assuming Windows Forms application
If you are opening Form2 as a modal form, MainForm is accessible to you as Owner. You can have a property on MainForm which you can initialise (put value in) just before closing the Form2.

Form2 is inherited with Mainform or not, if inherited then it is working as master page. So you have found on c# or vb code of form2 page.

so you can use on button click.
private void OnButton1Click(objectsender,EventArgse)
{
if(sender is Form)
{
this.Hide();
varform2=newForm2();
form2.Closed+=(s,args)=>this.Close();
form2.Show();
}

}

Hi Dante,
If you are using two winform ,when you are opening new window form you should hide Main winform using this code
privatevoidOnButton1Click(objectsender,EventArgse)
{
this.Hide();
varform2=newForm2();
form2.Closed+=(s,args)=>this.Close();
form2.Show();
}
to pass data you should create business layer in your application ,store data from Main form in class object and use on next winform class.
