(十八)c#Winform自定义控件-提示框

准备工作

这是一个提示消息的窗体,他继承自基类窗体FrmBase,如果你对FrmBase还不了解,请移步 (十七)c#Winform自定义控件-基类窗体 查看

提示消息窗体支持有确定取消按钮及单取消按钮,更多操作按钮暂没有增加

开始

添加一个Form命名为FrmDialog ,继承FrmBase

私有的构造函数

private FrmDialog(
            string strMessage,
            string strTitle,
            bool blnShowCancel = false,
            bool blnShowClose = false,
            bool blnisEnterClose = true)
        {
            InitializeComponent();
            if (!string.IsNullOrWhiteSpace(strTitle))
                lblTitle.Text = strTitle;
            lblMsg.Text = strMessage;
            if (blnShowCancel)
            {
                this.tableLayoutPanel1.ColumnStyles[1].Width = 1;
                this.tableLayoutPanel1.ColumnStyles[2].Width = 50;
            }
            else
            {
                this.tableLayoutPanel1.ColumnStyles[1].Width = 0;
                this.tableLayoutPanel1.ColumnStyles[2].Width = 0;
            }
            btnClose.Visible = blnShowClose;
            blnEnterClose = blnisEnterClose;
        }

效果:

调用示例

if (FrmDialog.ShowDialog(this, "是否再显示一个没有取消按钮的提示框?", "模式窗体测试", true) == System.Windows.Forms.DialogResult.OK)
{
    FrmDialog.ShowDialog(this, "这是一个没有取消按钮的提示框", "模式窗体测试");
}
