Hi Tanuj Kumar,\
If you want to invoke Form_Paint event on [button](https://www.mindstick.com/articles/63/how-to-add-button-in-datagridview-in-csharp-dot-net) [click event](https://www.mindstick.com/forum/12705/how-to-implement-click-event-on-textbox) then you have to write code in such way:**\**

```
public void draw(object sender, PaintEventArgs e)        {            try            {                using (LinearGradientBrush brush = new LinearGradientBrush(ClientRectangle, Color colr1, Color colr2, LinearGradientMode.Vertical))                {                    e.Graphics.FillRectangle(brush, ClientRectangle);                }            }            catch (Exception ex)            {                MessageBox.Show(ex.Message);            }        }private void btnApply_Click(object sender, EventArgs e)        {            Paint += draw;            Invalidate();        }
```

**\
I hope it might be resolve your problem.\**
