Suppose that your dynamic textbox is called txtDynamic. When you create it, you need to add an extra line to 'wire up' the Enter event: txtDynamic.Enter += txtDynamic_Enter; You now need to add the handler manually rather than via the VS designer as you would with 'static' textboxes: private void txtDynamic_Enter(object sender, EventArgs e) { TextBox tb = (TextBox)sender; tb.Text = ""; } Note that you can use the same event handler for any number of dynamic textboxes. The 'sender' parameter knows which one is being entered.

Just handle the textbox's Enter event as follows: private void textBox1_Enter(object sender, System.EventArgs e) { textBox1.Text = ""; }

Assuming that you've added a txtDynamic_Enter event handler as per my last post, then all you need to do is this: for (int i = 0; i { txt[i]=new TextBox(); txt[i].Name = "txt" + i.ToString(); txt[i].Text = "Enter Salary of " + (i + 1) + " month"; txt[i].Location = new Point(textBox1.Location.X, textBox1.Location.Y+(i+1)*30); txt[i].Size = new Size(150, 150); txt[i].Enter += txtDynamic_Enter; this.Controls.Add(txt[i]); }
