Hi, I have two TextBoxes. Both are dynamically created and width of both are set dynamically. So problem is that when I enter text in first textbox and it gets its end then remaining text should be entered in another textbox automatically.
For example while writing name in cheque, when first line is fulled then we move to another line given below it.

Thanks.

You need to use javascript for it. Track the number of characters in first textbox. The moment it crosses the fixed number(lets say 50), set the focus on next textbox.

You can use any one of the events to track the no. of character typed:
onchange, onBlurr, onFocusOut, onKeyUp....

Try something like this: It checks every time a user presses a key if it checks if it exceeds the textbox and if so if focusses the next one. Not sure if this code will work 100% on ASP.NET but I think it should give atleast a good idea on how this can be done.

void textBox1_KeyDown(object sender, KeyEventArgs e)
{

Size textSize = System.Windows.Forms.TextRenderer.MeasureText(textBox1.Text, textBox1.Font, textBox1.Size, TextFormatFlags.Default);

if(textSize.Width >= textBox1.Width)
{
  textBox2.Focus();
}

}
