My requirements: I need to get the visible state of custom control in saveViewState method, but saveViewSate meth

protected override object SaveViewState(){

}

By, generally saveViewState method did not accept any arguments, then how come i get the visible state of the control.

Answer 1

Yes, we can able to get the default properties of custom controls in SaveViewSate method as follows

protected override object SaveViewState(){

    object[] myState = new object[2];
    myState[0] = base.SaveViewState(); // this will store the default properties status such as visible,
    return myState;
}


protected override void LoadViewState(object state)
{
    object[] myState = null;
    if (state != null)
    {
        myState = (object[])state;
    }
    base.LoadViewState(myState[0]);
}

In LoadViewState, you can able to restore the state as above.
