Question

How I can convet viewstate to bool array

private bool[] clientCollapse

}

Any ideas???

Answer 1

private bool[] clientCollapse
{
    get { return (bool[])ViewState["Collapse"]; }
    set { ViewState["Collapse"] = value; }
}

if will work if you set those values only using this propery, otherwise you can but there other type and cast will not work

BTW common naming convention for C# requires property names to start with capital: ClientCollapse

Answer 2

You can do this:

private bool[] clientCollapse
{
    get { return (bool[])ViewState["Collapse"] ?? new bool[0]; }
    set { ViewState["Collapse"] = value; }
}
