how to remove the rows of datagridview of one form from another form

Question

Hi

In a form say form2's load event I will retrive some information and based on the condition I will add that data as a row to the dgv or an empty row if the condition fails as below.

private void form2_load(object sender, EventArgs e)
{
if (list6.ElementAtOrDefault(i) == "09:00:00")
{
String[] row = { "9.00-9.30 AM", "", list2.ElementAtOrDefault(i), list3.ElementAtOrDefault(i), list8.ElementAtOrDefault(i), "",......, };

dataGridView1.Rows.Add(row);

i++; ;
}
else
{
String[] row = { "9.00-9.30 AM", "", "", "", "", "", "", "", "", "", "", "", "", "", "" };
dataGridView1.Rows.Add(row);
}

if (list6.ElementAtOrDefault(i) == "09:30:00")
{
String[] row = { "9.30-10.00 AM", "", list2.ElementAtOrDefault(i), list3.ElementAtOrDefault(i), list8.ElementAtOrDefault(i), "", ......., };

dataGridView1.Rows.Add(row);
i++; ;
}
else
{
String[] row = { "9.30-10.00 AM", "", "", "", "", "", "", "", "", "", "", "", "", "", "" };
dataGridView1.Rows.Add(row);
}

if (list6.ElementAtOrDefault(i) == "10:00:00")
{
String[] row = { "10.00-10.30 AM", "", list2.ElementAtOrDefault(i), list3.ElementAtOrDefault(i),..................,};

dataGridView1.Rows.Add(row);
i++; ;
}

else
{
String[] row = { "10.00-10.30 AM", "", "", "", "", "", "", "", "", "", "", "", "", "", "" };
dataGridView1.Rows.Add(row);
}

}

In Form2 Write a Public Method public void DeleteRow() { int deleteindex =dataGridView1.CurrentRow.Index; dataGridView1.Rows.RemoveAt(deleteindex); } in Form 7 in buttons Click Event Write code like Below private void button1_Click(object sender EventArgs e) { //Delete Row of Form2 FormCollection fc = Application.OpenForms; foreach (Form f in fc) { if (f.Name == Form2) { ((Form2)(f)).DeleteRow(); } } }

private void button1_Click(object sender EventArgs e) { //Delete Row of Form2 FormCollection fc = Application.OpenForms; foreach (Form f in fc) { if (f.Name == Form2) { // Caste f in Form2 So That we can Get DeleteRow() Method in Intellisence List and Invoke DeleteRow Method of the Founded Form2 's Instance ((Form2)(f)).DeleteRow(); } } }

Thanks kirtan for your kind reply. Kirtan I have undestood your code but I didn't get what the below code does FormCollection fc=Application.OpenForms; // gets the collection of forms foreach(Form f in fc) // looping for forms { if(f.Name==Form2) // if the selected form is Form2 { ((Form2).(f)).Deleterows(); // what this does??? } }
