Update textboxes in Form1 on updating the datagridview

Question

Hi all I have coded where my functionality as follows, In my form1 I will have some text boxes and a datagridview where when user click on edit of the datagridview form2 will come as popup and if the user make some changes I will update the changes and rebind the datagridview this is my code

// Form1 Code

public void UpDateData(DataTable dt)

{

dataGridView1.Refresh();

dataGridView1.DataSource = dt;

updateTextBoxes();

}

public void updateTextBoxes()

{

// Some caluculation based on the datagridview rows

}

Form2 Button click code

private void button1_Click(object sender, EventArgs e)

{

// Some code to collect the changes made

Form1 f=new Form1();

f.UpDateData(lDTGet);

}

Every thing works fine except the updateTextBoxes method this is not updating the textboxes as per required can some one help me

after calculation and other thing add one more line at the end public void updateTextBoxes() { .//your code here Application.DoEvents(); }

On Form2 you appear to be creating a new instance of Form1 rather than using the existing instance. I'd try replacing this line: Form1 f=new Form1(); with: Form1 f = (Form1)Application.OpenForms[Form1];
