Hi,

Im my project, i have a requirement (rather small). Depending on the Checked/Unchecked state of check box, many other controls needs to be enabled/disabled.

For example take a check box and an edit control.

Programatically we can do it as :
textbox.Enabled = checkbox.Checked;

Can we make any settings in control's properties so that we need not handle them in our application?

Thanks in Advance

according to my knowledge it is not possible to directly bind

there is a way that on checked change event you can enable/disable all the controls

Are you using WPF or WinForms ?

You can use Binding.

You asked about DependencyProperty. So, you propably meant to a WPF solution.

Using WPF, you can set a name to your CheckBox, like the following:

XML

<CheckBox x:Name="cbEnableControls" Content="Enable controls"/>

and, bind the IsEnabled property to the IsChecked property of the CheckBox, like the following:

XML

<TextBox IsEnabled="{Binding IsChecked, ElementName=cbEnableControls}" />

But, the code example looks like WinForms. If you use Winforms, see the MSDN topic about the Binding class.

following code will enable/disable all controls of your active form on the basis of checked state of your checkbox

C#

private void cbxEnableControls_CheckedChanged(object sender, EventArgs e)
{
    EnableControls(cbxEnableControls.Checked);
}

private void EnableControls(bool Enable)
{
    foreach (Control c in this.Controls)
        c.Enabled = Enable;
}
