Dear Sir,

Please help to send string value from one page to another page in ASP.Net.

namespace OCMS
{
    public partial class lgn : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            int companyId;
            string constr = ConfigurationManager.ConnectionStrings["constr"].ToString();
            using (SqlConnection con = new SqlConnection(constr))
            {
                using (SqlCommand cmd = new SqlCommand("SELECT * FROM tbl_Employees WHERE EmpCode=@EmpCode AND UserName=@UserName", con))
                {
                    DataTable dt = new DataTable();
                    SqlDataAdapter sda = new SqlDataAdapter(cmd);
                    cmd.Parameters.AddWithValue("@EmpCode", txtUserName.Text);
                    cmd.Parameters.AddWithValue("@UserName", txtPassword.Text);
                    sda.Fill(dt);
                    if (dt.Rows.Count > 0)
                    {
                        companyId = int.Parse(dt.Rows[0]["CompanyId"].ToString());
                        switch (companyId)
                        {
                            case 1003:
                                Response.Redirect("Index.aspx");
                                break;
                            case 1002:
                                Response.Redirect("It_admin.aspx");
                                break;
                            //case 3:
                               // Response.Redirect("Elec_Twn_Comp.aspx");
                               // break;
                           // case 4:
                               // Response.Redirect("Elec_Plnt_Comp.aspx");
                                //break;
                          //  case 5:
                              //  Response.Redirect("Cvl_Twn_Comp.aspx");
                               // break;
                            //case 6:
                               // Response.Redirect("Cvl_Plnt_Comp.aspx");
                               // break;
                            //case 7:
                                //Response.Redirect("Hr_Comp.aspx");
                               // break;
                        }
                    }
                }

Hi indradeo,

For sending string value to another page you can use QueryString or Session.

Refer below example with both.

HTML

Default

Name:
<asp:TextBox ID="txtName" runat="server" Text="Mudassar Khan" />
<asp:Button ID="btnSendQueryString" Text="Send using QueryString" runat="server" OnClick="OnSendQueryString" />
<asp:Button ID="btnSendSession" Text="Send using Session" runat="server" OnClick="OnSendSession" />

Home

<asp:Label ID="lblName" runat="server" />
<br />
<asp:Button Text="Back" runat="server" OnClick="OnBack" />

Code

Default

protected void OnSendQueryString(object sender, EventArgs e)
{
    string name = txtName.Text;
    Response.Redirect(string.Format("~/Home.aspx?name={0}", name));
}

protected void OnSendSession(object sender, EventArgs e)
{
    Session["Name"] = txtName.Text;
    Response.Redirect("~/Home.aspx");
}

Home

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["Name"] != null)
    {
        lblName.Text = Session["Name"].ToString();
    }

    if (!string.IsNullOrEmpty(Request.QueryString["name"]))
    {
        lblName.Text = Request.QueryString["name"];
    }
}

protected void OnBack(object sender, EventArgs e)
{
    Response.Redirect("~/Default.aspx");
}

VB.Net

Default

Protected Sub OnSendQueryString(ByVal sender As Object, ByVal e As EventArgs)
    Dim name As String = txtName.Text
    Response.Redirect(String.Format("~/Home.aspx?name={0}", name))
End Sub

Protected Sub OnSendSession(ByVal sender As Object, ByVal e As EventArgs)
    Session("Name") = txtName.Text
    Response.Redirect("~/Home.aspx")
End Sub

Home

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    If Session("Name") IsNot Nothing Then
        lblName.Text = Session("Name").ToString()
    End If

    If Not String.IsNullOrEmpty(Request.QueryString("name")) Then
        lblName.Text = Request.QueryString("name")
    End If
End Sub

Protected Sub OnBack(ByVal sender As Object, ByVal e As EventArgs)
    Response.Redirect("~/Default.aspx")
End Sub
