I came across some code on w3schools that I'd like to use: TryIt
Does anyone know how I can incorporate it with an asp:LinkButton or asp:Button using OnClientClick, while still having onClick run the server-side code?

Just recently I added a snackbar feature to my project, even though it's been almost a year since everyone else started using it.
To make the snackbar work, you'll need an UpdatePanel and register a client script block in your event handler:
<asp:UpdatePanel runat="server" ID="UpdatePanel1">
<ContentTemplate>
<div>
<asp:Button runat="server" ID="ShowSnackbar" Text="Show Snackbar" OnClick="ShowSnackbar_Click" />
</div>
<div id="snackbar">
<asp:Label runat="server" ID="Snack" />
</div>
</ContentTemplate>
</asp:UpdatePanel>
The back-end coding was a bit challenging, but it does the job effectively. You need to create a javascript string on page load and use that string value to register your script block...
private string snackbarScript;
protected void Page_Load(object sender, EventArgs e)
{
snackbarScript = GenerateSnackbarJS();
}
private string GenerateSnackbarJS()
{
var sb = new StringBuilder();
sb.AppendLine("var x = document.getElementById('snackbar');");
sb.AppendLine("x.className = 'show';");
sb.AppendLine("setTimeout(function(){ x.className = x.className.replace('show', ''); }, 3000);");
return sb.ToString();
}
protected void ShowSnackbar_Click(object sender, EventArgs e)
{
Snack.Text = "Here's the snackbar";
ScriptManager.RegisterClientScriptBlock(this.Page, this.Page.GetType(), "snackbar", snackbarScript, true);
