In this article I will explain with an example, how to display (show) success message after record inserted (Form Submit) in ASP.Net using C# and VB.Net.
This article will illustrate how to display (show) success message using
JavaScript alert
MessageBox after record inserted (Form Submit) in ASP.Net.
HTML Markup
The HTML Markup consists of following controls:
TextBox – For capturing user input.
Button – For displaying MessageBox.
The Button has been assigned with an OnClick event handler.
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td>Name:</td>
<td><asp:TextBox ID="txtName" runat="server" /></td>
</tr>
<tr>
<td>City:</td>
<td><asp:TextBox ID="txtCity" runat="server" /></td>
</tr>
<tr>
<td>Country:</td>
<td><asp:TextBox ID="txtCountry" runat="server" /></td>
</tr>
<tr>
<td></td>
<td><asp:Button ID="btnSave" Text="Save" runat="server" OnClick="Save" /></td>
</tr>
</table>
Displaying MessageBox when user submits the Form
When the Save Button is clicked, a message is set and StringBuilder class object is created.
message – The message to be displayed in the
JavaScript Alert
MessageBox.
Here, StringBuilder class object is used to create a script (in HTML) for Alert message.
Finally, the
StringBuilder class object is passed as parameter to
RegisterStartupScript method of
ClientScript class which ultimately displays the
JavaScript Alert
MessageBox.
C#
protected void Save(object sender, EventArgs e)
{
//Insert record here.
string message = "Your details have been saved successfully.";
StringBuilder sb = new StringBuilder();
sb.Append("<script type='text/javascript'>");
sb.Append("window.onload = function(){ alert('");
sb.Append(message);
sb.Append("');");
sb.Append("</script>");
ClientScript.RegisterStartupScript(this.GetType(), "SuccessMessage", sb.ToString());
}
VB.Net
Protected Sub Save(ByVal sender As Object, ByVal e As EventArgs)
'Insert record here.
Dim message As String = "Your details have been saved successfully."
Dim sb As StringBuilder = New StringBuilder()
sb.Append("<script type='text/javascript'>")
sb.Append("window.onload = function(){ alert('")
sb.Append(message)
sb.Append("');")
sb.Append("</script>")
ClientScript.RegisterStartupScript(Me.GetType(), "SuccessMessage", sb.ToString())
End Sub
