Disable all controls in...

Edwin Knoppert · Jan 22, 2006

I have a div which holds controls.
I'm looking for a way to disable all controls but *without* setting each
control enable state.
Same to style>display i'm looking for a disable method.

Do i need a container control for this?

Hi Edwin,

Yes, using a Panel WebControl would probably be a good way to solve your
problem.

Groete,

You can use a container control or make the div a server side control:

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

<div id="div1" runat="server">

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

<asp:Button ID="Button1" runat="server" />

</div>

</form>

</body>

div1.Visible = false;

I did the same, like i said, visible does work, disabling instead.. how?

Edwin,

Only ASP.NET server controls contain the Enabled property. If you are using
all server side controls, you can do the following:

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

laceHolder ID="PlaceHolder1" runat="server">
<asp:TextBox ID="TextBox1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" />
</asp

laceHolder>
</div>
</form>
</body>

in code:

foreach (WebControl control in PlaceHolder1.Controls)
{
control.Enabled = false;
}

If you attempt to use this with an HTML control such as an <IMG> or <INPUT>
tag, you will throw an InvalidCastException.

Hope this helps.

Enable Disable, all controls inside a div / placeholder

ASPX Page:

Code:

 <asp:PlaceHolder ID="placeHolderMyServerControl" runat="server"></asp:PlaceHolder>

Code Behind:

Call Function:

Code:

private bool condition;

protected override void CreateChildControls()
{
   base.CreateChildControls();
   MyServerControl serverControl = new MyServerControl();
   placeHolderMyServerControl.Controls.Add(serverControl);
}

protected override void OnPreRender(EventArgs e)
{
  base.OnPreRender(e);
  MyCondition();
  if(condition == true)
  {
     EnableControl(true, placeHolderMyServerControl.Controls);
  }
  else
  {
     EnableControl(false, placeHolderMyServerControl.Controls);
  }
}

Create Function:

Code:

/// <summary>
/// Enable Disable Control
/// </summary>
/// <param name="enabled">true or false</param>
/// <param name="controls">Controls Collection</param>
 private void EnableControl(bool enabled, ControlCollection controls)
        {
           foreach (Control childControl in control)
           {
               try
               {
                   WebControl webChildControl = (WebControl) childControl;
                   webChildControl.Enabled = enabled;
               }
               catch
               {
                   
               }
               finally
               {
                   EnableControl(enabled, childControl.Controls);
               }
           }
        }


//Your Condition
private void MyCondition()
{
//Put your own if condition
  if()
  {
   condition = true;
  }
  else
  {
   condition = false;
   }
}
