Question

Changing Control's property in Update Panel

Answer 1

A:

I created a new ASP.NET website in Visual Studio 2008 SP1 with .NET 3.5 as the target framework. I was able to use the value from a readonly textbox to update the value of a label.

Here is the example:

Designer:

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head runat="server">
    <title></title>
</head>

<body>
    <form id="form1" runat="server">

    <div>
    <asp:textbox ID="Textbox1" runat="server" ReadOnly="True"></asp:textbox>
    </div>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </form>
</body>
</html>

Code behind:

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
       Textbox1.Text = "GANESH";
       Label1.Text = Textbox1.Text;
    }
}

Any inputs from you will help us help you.

ohh...But one question, if the user cannot change the data, why not use the data from the data source which was used to fill in the data in the textbox in the first place.

Hi,

Try Using this.. It will get all the controls in Panel...

 Private Sub clearReadOnlyTextboxes(ByVal pg As Control)
            For Each c As Control In pg.Controls
                Select Case TypeName(c)
                    Case Is = "TextBox"
                        If c.[GetType]().ToString() = "System.Web.UI.WebControls.TextBox" AndAlso DirectCast(c, TextBox).[ReadOnly] Then
                            DirectCast(c, TextBox).[ReadOnly] = False
                            DirectCast(c, TextBox).Attributes.Add("readonly", "readonly")
                        End If
                    Case Is = "Panel"
                        clearReadOnlyTextboxes(c)
                    Case Is = "HtmlForm"
                        clearReadOnlyTextboxes(c)
                End Select
