C＃WinForm：提交另一个表单后重新加载表单？

Question

I'm newbie of winform. I have opened form2 form a linklabel in form1 using :

private void linkLabel2_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    FrmAddMov frmAddMov = new FrmAddMov();
    if(frmAddMov.ShowDialog() == DialogResult.OK)
    {
        this.Invalidate();
        //or
        this.Refresh();
    }
}

I thought form1 will reload after I submit form2, but not. Please tell me the right way to do it. Thanks a lot, and sorry if my english is too bad.

Answer 1

Move everything in your form load event to a method say FormLoad. You may want to add few other statements which you are expecting form reload will do for you. Call this method when your 2nd form closes.

Something like this

private void linkLabel2_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
    {
        FrmAddMov frmAddMov = new FrmAddMov();
        if(frmAddMov.ShowDialog() == DialogResult.OK)
        {
           FormLoad();
        }
    }

Answer 2

Gentleman's answer will work, but it can be improved.
When showing a form using ShowDialog than it is best practice to dispose of that form, and the easiest way to do that is by the using statement

private void linkLabel2_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    using (FrmAddMov frmAddMov = new FrmAddMov())
    {
        if (frmAddMov.ShowDialog() == DialogResult.OK)
        {
           FormLoad();
        }
    }
}

This way you are always 100% sure that all resources for frmAddMov will be cleaned up.
