求各位帮帮忙。。。windowsform

[lovemengmeng201314]

我现在有两个窗口；一个作为主界面，另一个是一对话框的形式出现；

我的目的：想单击对话框那个界面的button按钮时，在主界面中显示相应的信息；

问题是：每点击一次，就会出现一个一样的主界面；请问怎么解决？？？？
代码：form1中

private void btnEnterInsetStep_Click(object sender, EventArgs e)
{
this.Close();
Form1 f1 = new Form1();
f1.Show();
int index = f1.dgvRecipeEdit.Columns.Add("C", "");
string headerText = "step" + index.ToString();
f1.dgvRecipeEdit.Columns[index].HeaderText = headerText;
f1.dgvRecipeEdit.Columns[index].SortMode = DataGridViewColumnSortMode.NotSortable;
f1.dgvRecipeEdit.Columns[index].DefaultCellStyle.Font = new Font("宋体", 11F);
f1.dgvRecipeEdit.Columns[index].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
f1.dgvRecipeEdit.Columns[index].Width = 130;

}
form2中：
private void btnInsertRecipeStep_Click(object sender, EventArgs e)
{
FormInsertStep fis = new FormInsertStep();
fis.ShowDialog();

参考二楼吧，窗体传值，我一般都是采用委托

你用下单例模式应该可以解决了

代码：form1中

private void btnEnterInsetStep_Click(object sender, EventArgs e)
{
this.Close();
Form1 f1 = new Form1();
f1.Show();
int index = f1.dgvRecipeEdit.Columns.Add("C", "");
string headerText = "step" + index.ToString();
f1.dgvRecipeEdit.Columns[index].HeaderText = headerText;
f1.dgvRecipeEdit.Columns[index].SortMode = DataGridViewColumnSortMode.NotSortable;
f1.dgvRecipeEdit.Columns[index].DefaultCellStyle.Font = new Font("宋体", 11F);
f1.dgvRecipeEdit.Columns[index].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
f1.dgvRecipeEdit.Columns[index].Width = 130;

}
form2中：
private void btnInsertRecipeStep_Click(object sender, EventArgs e)
{
FormInsertStep fis = new FormInsertStep();
fis.ShowDialog();

在form1，中show form1，那就只能出现form1窗体了

    private void btnEnterInsetStep_Click(object sender, EventArgs e)
  {
  this.Close();
  Form1 f1 =Form1.GetInstance();
  f1.Show();
......................
}




FormInsertStep 窗体中  
 
     static   FormInsertStep form = null;

        public static   FormInsertStep GetInstance()
        {
            if (form == null || form.IsDisposed)
            {
                form = new   FormInsertStep();
            }
            return form;
        }

Form1 窗体中  
 
     static   Form1 form = null;

        public static   Form1  GetInstance()
        {
            if (form == null || form.IsDisposed)
            {
                form = new   Form1 ();
            }
            return form;
        }

上面看错了
