大家好，

我有一个母版页和许多内容页.

在该内容页面中，我有一个DropDownList框.

我必须像这样
访问MasterPage内部的DropDownList控件

Hi to all,

I have one Master Page and many number of Content page.

With in that Content pages I have the DropDownList box.

I have to access the DropDownList Control inside of the MasterPage like this

protected void Page_Load(object sender, EventArgs e)
 {

ContentPlaceHolder ct = (ContentPlaceHolder)Master.FindControl(sender.ToString());
        ControlCollection CCl = ct.Controls;
        
        foreach (Control ctrl in CCl)
        {
            if (this.Controls.GetType() == typeof(DropDownList))
            {
                strDropDownID = ((DropDownList)ctrl).ID;
                if ((strDropDownID.Contains("ddlCountry")) || (strDropDownID.Contains("ddlFromCountry")) || (strDropDownID.Contains("ddlToCountry")) || (strDropDownID.Contains("ddlOrginCountry")) || (strDropDownID.Contains("ddlDestinationCountry")))
                {
                    ClientScriptManager cs = Page.ClientScript;

                    // Check to see if the client script is already registered.

                    if (!cs.IsClientScriptBlockRegistered(this.GetType(), "DropDownListScript"))
                    {

                        StringBuilder cstext2 = new StringBuilder();

                        cstext2.Append("<script type=''text/javascript''> function SelectCountry(''" + strDropDownID + "'') {");

                        cstext2.Append("script>");

                        cs.RegisterClientScriptBlock(this.GetType(), "DropDownListScript", cstext2.ToString(), false);

                    }
                }
            }

        }
}

代码的第一行获取内容页面名称，但给出错误.

我不知道如何获取当前页面的页面名称，该页面称为主页面.

如果您知道在母版页中访问页面名称的解决方案
这对我很有帮助.

感谢所有人.

The first line of the code gets Content page name but it gives an Error.

I dont know how to get the Page name of the Current Page which one is calling the Master Page.

If you know the solution to access the page name inside the master page
it would help me very much.

Thanks to all.
