If you are asking what I think you are asking, this[^] is how you write an if statement in C#.

The framework has a nice tool to help here[^]. Check out the DrawCheckBox Method[^] overloads.

checkbox control checked property will only return either true or false. Also the text property only returned the text associated with the control.
One way around that I come up is that:
You will have to write an if statement before the e.Graphics.Drawstring.
if(metroCheckBox.checked)
{
>e.Graphics.DrawString("Customer Items: " + metroCheckBox1.Text, new Font("Arial", 14, FontStyle.Regular), Brushes.Black, new Point(25, 320));
}
else
{
}

I've been playing with jsPDF[^] lately. Aside from highly limited CSS support, it's fairly excellent.
The AutoTable plugin also works exceptionally well.

Is there a better way to run the Stop Watch:
Form1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Diagnostics;
namespace StopWatch
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
Stopwatch StopWatch = new Stopwatch();
private void lblClock_Click(object sender, EventArgs e)
{
}
private void btnStart_Click(object sender, EventArgs e)
{
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
timer1.Start();
this.StopWatch.Start();
}
private void btnStop_Click(object sender, EventArgs e)
{
if (timer1.Enabled)
{
timer1.Stop();
StopWatch.Stop();
}
else
MessageBox.Show("Timer Already Stopped");
}
private void btnPause_Click(object sender, EventArgs e)
{
StopWatch.Reset();
lblClock.Text = "00 HR :00 MIN :00 SEC ";
}
private void timer1_Tick(object sender, EventArgs e)
{
TimeSpan elapsed = this.StopWatch.Elapsed;
lblClock.Text = string.Format("{0:00} HR :{1:00} MIN: {2:00} SEC", Math.Floor(elapsed.TotalHours), elapsed.Minutes, elapsed.Seconds);
}
}
}
Class1.cs
using System;
using System.Collections.Generic;

This very much depends on the application and level of accuracy required. Your sample provides the simplest solution, but it lacks a degree of accuracy, as everything is processed on the UI thread. Using this system, a timer event is actually placed on the message queue when it is signalled, and thus needs to wait its turn to be processed. This can cause a delay small in the processing of the tick, which over time, may accumulate.
To go to the next level of accuracy, you need to look at a System.Threading.Timer[^]. These fire events off in another thread, so there is no queue delays. It does, however, take a bit of effort to marshal the results back to the UI thread to update your controls.
The most accurate timer is the High Resolution Timer used in the Stopwatch Class[^]. This does not fire its own events at all, so you need to monitor its values in a separate thread, fire the periodic events in another thread, and then marshal all the results back to the UI for display.
All three options are good fun!
Cheers,
Mick

Don't use a StopWatch - just get the current DateTime.Now when you start the timer, and again when you stop (or lap check) it.
The Timespan difference will give you all the information you need.

Ehm, that looks like a hidden bug:
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
timer1.Start();
this.StopWatch.Start();
Did you really mean that? Or rather
if (timer1.Enabled)
{
MessageBox.Show("Sorry you have already started the Timer");
}
else
{
timer1.Start();
this.StopWatch.Start();
}
Anyway, I recommend to always use {} with if and else - also with one-liners.

There is no problem with your code if that can solve your problem. From design point of view it looks great.
As one answer above mentioned that you can use many other types of solution to accomplish timing and scheduling task. That also depend upon your needs.
If you need a precise timer such as with 1ms accuracy (Stopwatch can very up-to 20-100 ms) then you should use multimedia timers.

Below is my Kendo code:
@(Html.Kendo().ComboBox()
.Name("cboTeamCode")
.HtmlAttributes(new { style = "width:90%;" })
.DataTextField("Team")
.DataValueField("Team")
.Placeholder("Select Team").Filter("contains").AutoBind(false).MinLength(1)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetTeamList", "Main"); //Set the Action and Controller names.
})
.ServerFiltering(true); //If true, the DataSource will not filter the data on the client.
})
.SelectedIndex(0)
)
Below is my Action method:
public JsonResult GetTeamList()
{
return Json(dba.GlobalDefaults, JsonRequestBehavior.AllowGet);
}
When I am running my code I am getting below error:
Error: Object doesn't support property or method 'requestData'
Below is the debugger code:
jQuery(function(){jQuery("#cboTeamCode").kendoComboBox({"dataSource";:{"transport":{"read":{"url":"/Main/GetTeamList","data":function() { return kendo.ui.ComboBox.requestData(jQuery("#cboTeamCode")); }},"prefix":""},"serverFiltering":true,"filter":[],"schema":{"errors":"Errors"}},"dataTextField":"Team","filter":"contains","minLength":1,"autoBind":false,"dataValueField":"Team","index" ,"placeholder":"Select Team"});});
