Winform -- 我的记录

子窗体:
------------------------------------------------------
//委托EventHandler不能传递参数, 如需传递最好定义一个新的公共委托变量
public event EventHandler RefreshParent = null;

protected void OnRefreshParent()
{
    if (RefreshParent != null)
    {
        RefreshParent(this, EventArgs.Empty);
    }
}

//保存
private void btnSave_Click(object sender, EventArgs e)
{
    OnRefreshParent();
    this.Close();
}



父窗体:
------------------------------------------------------
private void btnAdd_Click(object sender, EventArgs e)
{
    Child sortEdit = new Child();
    //使用父窗体的方法实例化一个委托, 并注册到子窗体的事件上
    Child .RefreshParent += new EventHandler(Child _RefreshParent);
    Child .Show();
}

void Child_RefreshParent(object sender, EventArgs e)
{
    ...
}

 

//绑定品牌
private void comBrandBinds()
{

    //绑定数据源之外的行,需先插入再绑定

    dr["Name"] = "";
    dr["ID"] = "0";
    dt.Rows.Add(dr);

    comBrand.DataSource = dt;

    lvImage.TileSize = new Size(90, 90);
   
    for(int i=0; i<pictureList .Count ;i++)
    {
        Picture p = pictureList [i];
        //imageList需先定义好(直接拖控件)并设置图片尺寸和清晰度
