Trying to programmatically set textbox value

[Jason]

I use the NeedDataSource Event to bind a table from the resultset of a stored procedure. In the table I have a text box(textBox7) in which sometimes there is a visible value, other times there is not. I want to test to see if there is a value in this textbox. I
I
f there is, I want to set the value of textBox6 to "Yes". If textBox7 does not have a value, make the value of TextBox6 equal to "No". I am using the ItemDataBound event of TextBox6 to try to achieve this. Right now the value of textBox6 always ends up being "Yes" . However, this is not correct. I need to know how to write a valid test for the value of TextBox7, or if I am doing something else wrong. Code is below. Any help would be greatly appreciated.

        private void textBox6_ItemDataBound(object sender, System.EventArgs e)
        {

            if (textBox7.Value != null || textBox7.Value=="")
            {
                textBox6.Value = "Yes";
            }

            else
            {

                textBox6.Value = "No";
            }
        }
    }

Hi Jason,

You have modified the definition TextBox item instead of the processing counterpart (the sender argument), thus all subsequent processing items will be modeled after the modified reporting item.

Check out the following help articles:

Generally speaking for similar cases our suggestion is to use Bindings instead of Events. You can achieve your requirement as shown in the following sreenshoot:
