Considering you have a textbox that displays a message every time a control(button) is pushed. Each time the button gets pushed, some even will rise and you are displaying the result in a textbox.
Now if you want to automatically disappear the message on the textbox, following that event, you will need to set the textbox empty after a few seconds.
This post is particularly about how to clear textbox after few seconds in c# and I have added an example for demonstration purpose.
Steps to clear textbox after few seconds in c#
Basically, we have to take advantage of the Timer class (Windows.Forms.Timer) that will allow us to rise and event at user-defined intervals. Then we can use the Timer.Tickthat will occur when the given time interval has elapsed.
Make sure to use:
using System.Windows.Forms;Then follow this:
public partial class Form1 : Form
{
private Timer x = new Timer();
public Form1()
{
x.Interval = (6000); //1 second = 1000
x.Tick += new EventHandler(TimerTask); //evoke your custom event
x.Start();
}
// describe your method
}Then create a event to clear your textbox or anything you want to perform after the configured time frame.
private void TimerMethod(object sender, EventArgs e)
{
// do your job here
}In this example, I needed to clear the string (message) from textbox.
How to clear a textbox in c#?
Just set the string to empty for the desired textbox.
TextboxName.Text = String.Empty;Here’s the complete code required:
using System.Windows.Forms;
public partial class Form1 : Form
{
private Timer x = new Timer();
public Form1()
{
x.Interval = (6000); //1 second = 1000
x.Tick += new EventHandler(TimerTask);
x.Start();
}
private void TimerTask(object sender, EventArgs e)
{
TextboxName.Text = String.Empty;
}

I know it’s not necessary, most people already know what they are looking for, however, if you need an working example, I have added one here.
I tried this method with a demo application where I need to display a message after browsing and uploading a file. Depending on the uploading process a text box will display the message whether it’s a success message or warning.
But I need to flush or reset the textbox after 5 or 6 seconds every time the message appears. So I have a textbox in the form where the timer needs to do his work.
And I add the exact same code as mentioned above in the .cs file;
Now every time I upload a file a message will be displayed for 6 seconds and then disappear on the UI. I have taken a few snapshot, you will find them in the slider below.
How to reset a form after a few seconds?
If you have a form and want to reset it after a successful submission message in a specific time range then you can create a button_click_event like this;
For the form submit button;
protected void btnSubmit_click(object sender, EventArgs e)
{
textboxName.text = "Your message has been sent";
textboxName.Visibile = true; // will display the message
MainForm.Visible =false; // Hide the form
Response.AddHeader("Refresh", "4") // refresh the page in 4 sec
}Set label content and make it disappear automatically
For a label to disappear automatically after a given time that can be reinvoke on a button click can be something like this.
- Use a timer.
- On callback, set the label content empty.
- Restart the timer every time the button gets clicked.
- … and the process continues.
The implementation using timer class would be;
private Timer timer;
private void btnClick(object sender, RoutedEventArgs e)
{
Label = "Display your message here";
if(timer == null)
{
timer = new Timer(state => Label = String.empty, null, 5_000, Timeout.Infinte);
}
else
{
timer.Change(5_000, Timeout.Infinte);
}
