Hi,
i have asp.net web application in which i used to generate list of text boxes depend on count in table dynamically.however whenever I load the details I am getting the same output in the TextBox every time.

What I have tried:

after generating all controls(TextBox,dropdownlist etc) i am doing this below

TextBox txtRes1 = (TextBox)PlaceHolder1.FindControl("id1");
txtRes1.Text= concat(value1, valu2);

public int concat(strin v1, string v2)
{
return v1+v2;
}

Are you checking for post-back in your page load?

I only came across your comment by accident - if you want someone to be notified that you are replying then use the "Reply" link on their post.
You need to share your page load code.

Thanks guys.
i got the solution for this by creating a TextChanged event of a textbox in which i wanted to put the new changed value.

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
string endDate = Request.Form[((TextBox)PlaceHolder1.FindControl("tb1")).UniqueID];
                                    string startDate = Request.Form[((TextBox)PlaceHolder1.FindControl("tb2")).UniqueID];

TextBox txtRes = (TextBox)PlaceHolder1.FindControl("tb31");
txtRes.Text = tbc.DateDiff(Convert.ToDateTime(endDate), Convert.ToDateTime(startDate));
}
