Question

I am coding a function which will take a Control Ctrl as Arguement and Modify the Control.Content of it.
Is there Any way to Get and Set the Content of any Control??

Code :

void RemoveHotKey(Control Ctrl, int KeyIndex)
{
    if (Ctrl.Content.ToString().Substring(KeyIndex, 1) == "_") // System.Windows.Controls.Control does not contain a definition for 'Content'
    {
        Ctrl.Content = Ctrl.Content.ToString().Remove(KeyIndex, 1); // System.Windows.Controls.Control does not contain a definition for 'Content'
    }
}

try this instead:

void RemoveHotKey(ContentControl Ctrl, int KeyIndex) 
{ 
    if (Ctrl.Content.ToString().Substring(KeyIndex, 1) == "_")
    { 
        Ctrl.Content = Ctrl.Content.ToString().Remove(KeyIndex, 1);
    } 
}

take a look here.

or this:

void RemoveHotKey(Control Ctrl, int KeyIndex)
{
    ContentControl contentCtrl = Ctrl as ContentControl;
    if (contentCtrl != null && contentCtrl.Content != null)
    {
        if (contentCtrl.Content.ToString().Substring(KeyIndex, 1) == "_")
        { 
            contentCtrl.Content = contentCtrl.Content.ToString().Remove(KeyIndex, 1);
        }
    } 
}

which is way less expensive than using reflection..
