Hi,

from your code it looks like you are storing string value in viewState. if it is so then below solution may help you,

C#

string strEmployee = ViewState["empIds"]?? "";   //ViewState contain "emp001,emp002,emp003";
string[] empIds = strEmployee.Split(',');

foreach (var item in empIds)
{
    // iterate for each item and process further.
}

hope this may help you,

thanks

Hi ,
Check this
First you have to Cast your ViewState

protected void Page_Load(object sender, EventArgs e)
{

    if (!IsPostBack)
    {
        List<string> st = new List<string>();
        st.Add("me");
        st.Add("mm");
        st.Add("ee");
        st.Add("rr");
        ViewState.Add("st", st);
    }
}
protected void Button1_Click(object sender, EventArgs e)
{
    if (ViewState["st"] != null)
    {
        List<string> stView = (List<string>)ViewState["st"];
        foreach (string item in stView)
        {
            TextBox1.Text += item;
        }
    }

}

Best Regards
