Are you referring to buttons being enabled or disabled? You may want to look at the enabled api of button controls.

Solution 2

The easy way is not to look at trying to change it to "clicked", but to disabled, or"greyed" instead.
That is easy: set the Button.Enabled property to "false" to disable it, and "true" to reenable it.

Handle the TextBox.TextChanged Event to reenable it.

Solution 1

Use WebControl.Enabled[^] property. All buttons properties are listed here: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button_properties.aspx[^]

C#

Button1.Enable = (TextBox1.Text.Length>0);

[EDIT]
Windows.Controls.Button Class[^]
Windows.Controls.Button properties[^]
[/EDIT]

Oh, why System.Web.UI.WebControls? The question says "Windows forms"...
Also, it makes sens in TextChanged event handler...
Whatever...
