I have green underline when i use "RegisterStartupScript"in login page, the message told me that (
"Warning 6 'System.Web.UI.Page.RegisterStartupScript(string, string)' is obsolete: '"The recommended alternative is ClientScript.RegisterStartupScript(Type type, string key, string script). http://go.microsoft.com/fwlink/?linkid=14202"'
C:\Users\mkf\documents\visual studio 2010\projects\WebApplication23\WebApplication23\login.aspx.cs 43 17 WebApplication23 )
So how can fix this problem??????
Page Code
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void imgBtnLogin_Click(object sender, ImageClickEventArgs e)
{
string userName = txtName.Text;
string pass = txtPass.Text;
string sqlSel = "select * from userRegister where username=@name and userPass=@pass";
if (operateData.login(sqlSel, userName, pass))
{
Session["userName"] = txtName.Text;
string sql = "select * from userRegister where userName='" + Session["userName"] + "'";
SqlDataReader sdr = operateData.getRow(sql);
sdr.Read();
if (Convert.ToBoolean(sdr["lock"]))
{
Session["userName"] = null;
RegisterStartupScript("true", "<script>alert('" + sdr["lockCause"].ToString() + "');location='index.aspx'</script>");
}
else
RegisterStartupScript("true", "<script>alert('Login is successful！Click to return Home');location='index.aspx'</script>");
}
else
{
RegisterStartupScript("false", "<script>alert('User name or password is incorrect！')</script>");
}
}
}
Client.RegisterStartupScript(typeof(page),"NameForScript","<script>alert('Login is successful！Click to return Home');location='index.aspx'</script>", true);
Sorry I was just giving an example of the syntax. Cliient.registerstarupscript(type,name for script,script, generate code) Type = this is always typeof(page) or Me.gettype() Name for script = a unique name for script input type string Script = script goes here
as string Generate code = this is Boolean and tells the method to place the code in the HTML markup I think hehe. I always set it to true Google client.registerstartupscript site: msdn.com Microsoft has a full write up on syntax and parameters. It's pretty
straight forward. You'll need to modify all of your calls to match this syntax.
The method, Page.RegisterStartupScript is obsolete, as the error says. And again, as the message already said, the recommended alternative is to use ClientScript.RegisterStartupScript. Replace all the Page.RegisterStartupScript
lines with ClientScript.RegisterStartupScript.
Can you please explane that in my code(can you change my code above for the new one) I gote some error when I change it to ClientScriptManager.RegisterStartupScript()
RegisterStartupScript("true","<script>alert('Login is successful！Click to return Home');location='index.aspx'</script>");
as
ClientScriptManager.RegisterStartupScript(this.GetType(), "true", "<script>alert('Login is successful！Click to return Home');location='index.aspx'</script>");
mkf
RegisterStartupScript("false","<script>alert('User name or password is incorrect！')</script>");
as
ClientScriptManager.RegisterStartupScript(this.GetType(), "false", "<script>alert('User name or password is incorrect！')</script>");
Thanks for Replay, I still have error when i replace it with new code???? The error"Error 1 An object reference is required for the non-static field, method, or property 'System.Web.UI.ClientScriptManager.RegisterStartupScript(System.Type, string, string)' C:\Users\mkf\Documents\Visual Studio
