var noOfTextBx =Convert.ToInt32(TxtBxNoOf.Text) ;

hi sanjeeb..

at first a textbox accepts the no. of textboxes to display upon btnclick.(suppose txtbox id is txtmain.) then the reqd no of txtboxes are displayed.therafter the text in txtmain is changed.

For eg:let initially text in txtmain be 5 and 5 textboxes are displayed after button click.
then text in txtmain is changed to 10.
Now the previous 5 txtboxes shud not be deleted instead 5 new txtboxes to be added.and also the text in prev 5 txtboxes shud not be changed.
Help me to solve this!!!

Hi,

For textBox_TextChanged event you should have to set AutopostBack = true for that TextBox

Hi,
you can do like this
In your aspx

In your code behind
private string _data;

protected void textBox_TextChanged(object sender, EventArgs e)
{
_data = _data + txtResult.Text;
}
