Display message in message box (pop up) in asp.net

Introduction: In this article I will explain how to display message in message box (pop up) in asp.net from server side (code behind)

Description:

Commonly we use the message box to show message of data insert, update, delete etc... Now I am going to explain the different ways to show a message:

Method 1:

C #:-

protected void Button1_Click(object sender, EventArgs e)

    {

        Response.Write("<script type=\"text/javascript\">alert('Messagebox Pop up Alert!!!');</script>");

    }

VB:-

  Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button3.Click

        Response.Write("<script type=""text/javascript"">alert('Messagebox Pop up Alert!!!');</script>")

    End Sub

Method 2:

C #:-

protected void Button1_Click(object sender, EventArgs e)

    {

       Messagebox("Messagebox Pop up Alert!!!");

    }

private void Messagebox(string Message)

    {

        Label lblMessageBox = new Label();

        lblMessageBox.Text =

            "<script language='javascript'>" + Environment.NewLine +

            "window.alert('" + Message + "')</script>";

        Page.Controls.Add(lblMessageBox);

    }

VB:-

   Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

        Messagebox("Messagebox Pop up Alert!!!")

    End Sub

    Private Sub Messagebox(Message As String)

        Dim lblMessageBox As New Label()

        lblMessageBox.Text = (Convert.ToString("<script language='javascript'>" + Environment.NewLine + "window.alert('") & Message) + "')</script>"

        Page.Controls.Add(lblMessageBox)

    End Sub

Method 3:

C #:-

   protected void Button1_Click(object sender, EventArgs e)

    {

        ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Messagebox Pop up Alert!!!')", true);

    }

VB:-

  Protected Sub Button2_Click(sender As Object, e As System.EventArgs) Handles Button2.Click

        ScriptManager.RegisterClientScriptBlock(Me, Me.[GetType](), "alertMessage", "alert('Messagebox Pop up Alert!!!')", True)

    End Sub
