在DetailsView的CommandField控件中注册javascript

在asp.net的DetailsView自定义javascript验证的时候，碰到了比较头疼的问题，折腾了许久。

给解决方案吧。

首先设置DetailsView的CommandField控件类型为ButtonType="Button"

  <asp:CommandField ButtonType="Button" ShowInsertButton="True" />

后台代码为 CommandField注册脚本

private void RegisterCommandFieldJS()
    {
        bool registered = false;
        foreach (Control ctrl in DetailsView1.Controls)
        {

            RegisteJS(ctrl, ref registered);

            if (registered)
            {
                return;
            }

            IterateChildControl(ctrl, ref registered);
        }
    }

    private void RegisteJS(Control ctrl, ref bool registered)
    {
        IButtonControl btn = ctrl as IButtonControl;

        if (btn != null)
        {

            if (btn.CommandName == "Insert")
            {
                string js = ClientScript.GetPostBackEventReference(
             new PostBackOptions(ctrl, "", "", false, true, false, false, true, ""))
             + ";return (Page_IsValid && confirm('Are you sure to continue?'));";

                ((WebControl)ctrl).Attributes.Add("onClick", js);
                ((WebControl)ctrl).ToolTip = "Click here to Insert";

                registered = true;
                return;
            }

        }

    }


    private void IterateChildControl(Control ctrol, ref bool registered)
    {
        foreach (Control ctrl in ctrol.Controls)
        {

            RegisteJS(ctrl, ref registered);

            if (registered)
            {
                return;
            }

            IterateChildControl(ctrl, ref registered);
        }
    }

    protected void DetailsView1_DataBound(object sender, EventArgs e)
    {
        RegisterCommandFieldJS();
    }

其中，

 string js = ClientScript.GetPostBackEventReference(
             new PostBackOptions(ctrl, "", "", false, true, false, false, true, ""))
             + ";return (Page_IsValid && confirm('Are you sure to continue?'));";

为RequiredFieldValidator等验证控件的注册代码
