ASP. NET Text Box Password Assignment Default Value Method

For ordinary text input boxes, you can use the following methods to assign default values:

<asp:TextBox ID="TextBox1" runat="server">12345</asp:TextBox>

After changing the type of input box to password, the password box on the page is always blank and the default value is lost:

<asp:TextBox ID="TextBox1" runat="server" TextMode="Password">12345</asp:TextBox>

Looking at the html code, it is found that the value attribute is missing, so you can only add another one to the code:

TextBox1.Attributes["value"] = "123456";
