What is the best way to show a message box in ASP.NET?

Question

What is the best way to show a message box in ASP.NET?

I've been trying to display a message box after successfully saving an item, but the solutions I found online haven't worked for me. Below is the code I'm currently using:

try
{
    con.Open();
    string pass="abc";
    cmd = new SqlCommand("insert into register values('" + 
                                       txtName.Text + "','" + 
                                       txtEmail.Text + "','" + 
                                       txtPhoneNumber.Text + "','" + 
                                       ddlUserType.SelectedText + "','" + 
                                       pass + "')", con);

    cmd.ExecuteNonQuery();
    con.Close();
    Response.Write("<script LANGUAGE='JavaScript' >alert('Login Successful')</script>");
}
catch (Exception ex)
{

}
finally
{
    con.Close();
}

@freelancer If you're utilizing ScriptManager, here's a code snippet for displaying a message:

string alertScript = "alert(\"Hello!\");";
ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", alertScript, true);

Create a custom MsgBox method for displaying alerts on your webpage.

public void DisplayAlert(string message, Page currentPage, object currentObject) 
{
    string alertMessage = "<SCRIPT language='javascript'>alert('" + message.Replace("\r\n", "\\n").Replace("'", "") + "'); </SCRIPT>";
    Type objectType = currentObject.GetType();
    ClientScriptManager scriptManager = currentPage.ClientScript;
    scriptManager.RegisterClientScriptBlock(objectType, alertMessage, alertMessage.ToString());
}

To use the custom msgbox function, simply call this line:

DisplayAlert("! your message !", this.Page, this);

{
    string alertMessage = "<SCRIPT language='javascript'>alert('" + message.Replace("\r\n", "\\n").Replace("'", "") + "'); </SCRIPT>";
    Type objectType = currentObject.GetType();
    ClientScriptManager scriptManager = currentPage.ClientScript;
    scriptManager.RegisterClientScriptBlock(objectType, alertMessage, alertMessage.ToString());
}

To use the custom msgbox function, simply call this line:

DisplayAlert("! your message !", this.Page, this);

Including the following code in your asp.net file will enable you to incorporate a MsgBox feature. Feel free to modify the function definition to suit your specific needs and preferences. Trust this information proves useful!

protected void Addstaff_Click(object sender, EventArgs e)    
    {   
 if (intClassCapcity < intCurrentstaffNumber)     
                {                  
            MsgBox("Record cannot be added because max seats available for the " + (string)Session["course_name"] + " training has been reached");

To implement client-side script functionality, you can utilize Microsoft's ClientScript.RegisterOnSubmitStatement method. This allows you to execute scripts when submitting a form.

String scriptText = 
        "alert('Hello!');";
    ClientScript.RegisterOnSubmitStatement(this.GetType(), 
        "ConfirmSubmit", scriptText);

Give it a try with the following code snippet:

ClientScript.RegisterStartupScript(this.GetType(), "JSScript", scriptText);

ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", scriptText); //recommended approach

Implement a simple JavaScript function with a single line of code - "alert("Hello this is an Alert")", and instead of using OnClick(), utilize the OnClientClick() method.

`<html xmlns="http://www.w3.org/1999/xhtml">
 <head runat="server">
 <title></title>
 <script type="text/javascript" language="javascript">
    function showAlert() {
        alert("Hello this is an Alert")

 </script>
 </head>
 <body>
 <form id="form1" runat="server">

The most effective approach involves utilizing minimal java directly within the Visual Studio GUI

Follow these steps: Navigate to a button and access the "OnClientClick" property (not found under events*) then enter:

return confirm('are you sure?')

This will display a dialog with transparent cancel and OK buttons over the current page. If cancel is selected, no postback will occur. Alternatively, if you only want an OK button, use this code:

alert ('i told you so')

Events like onclick function on the server side to execute your code, whereas OnClientClick operates on the browser side, providing a similar functionality to a basic dialog.
