"cannot convert from 'object' to 'string'"

@Mikkk - as requested :

        public bool _isChecked
        {
            get
            {
                if (ViewState["_isChecked"] == null)
                {
                    return false;
                }
                else
                {
                    return bool.Parse(ViewState["_isChecked"]);
                }
            }
            set
            {
                ViewState["_isChecked"] = value;
            }
        }

@Mikkk,

ok, thanks.  have updated scripting, am geting the following compiling error message as follows:

'object' does not contain a definition for .value (blue underline for .value)

@Limbeck

thank you for your contribution also.

the :  return bool.Parse((string)ViewState["_isChecked"]);  is compiling ok -- am just checking function itself is doing what I am hoping it should be achieving...

@Mikkk - I had to add the " ", in order to compile -- am checking functionality to confirm the script is performing as expected.

return (ViewState["_isChecked"]=="true");

In the calling procedure - I am using :

        protected void Page_PreRender(object sender, EventArgs e)
        {
            ViewState["_isChecked"] = RadioButton_Role.Checked;
           
           if (ViewState["_isChecked"] )
           {
                RadioButton_Role.Checked = false;
                RadioButton_StaffMember.Checked = true;
           }
        }

i.e. to check the Radio Button checked status (historic user interation changes to button status) and reconfigure on a PreRender request.

the line :

if (ViewState["_isChecked"]) is not compiling -- a casting error.

what I am trying to check if the state is true or false ... what I am doing wrong here please?


__updated procedure______________________________

       public bool _isChecked
        {
            get
            {
                if (ViewState["_isChecked"] == null)
                {
                    return false;
                }
                else
                {
                    return (ViewState["_isChecked"] == "true");
                    //return bool.Parse((string)ViewState["_isChecked"]);
                }
            }
            set
            {
                ViewState["_isChecked"] = value;
            }
        }
