推荐答案

hi


i有一个用户控件，其中包含id为txtname的文本框



我从default.aspx页面更改了文本框值，如下所示

hi
i have a user control which contain below textbox having id "txtname"

and i have change textbox value from default.aspx page like as below

((this.Master.FindControl("usercontrol") as UserControl).FindControl("txtname") as TextBox).Text = "pqr";

这也没关系。

This is also fine.

TextBox txt = ((UserControl)Master.FindControl("TextBox1")).FindControl("TextBox1") as TextBox;

for that you need to put usercontrol in other folder then use it check my code as below
in webconfig file
 <pages masterPageFile="~/Site.Master">
      <controls>
        <add src="~/UserControls/WebUserControl1.ascx" tagname="userControltag" tagprefix="uc1"></add>
      </controls>

    &lt;/pages&gt;

in site master
&lt;uc1:userControltag ID="usercontrol"  runat="server" /&gt;

in sitemaster.cs
you can access usercontrol.

please follow folder structure like usercontrol should be put in other fodler

UserControl ::- WebUserControl1.ascx
