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

sachi vasishta

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);
}

}

Accepted answer

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();
                }
            }

        }

                 // 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???
}
}
