I want to make a page with the name entered in TextBox. After submission, I can find the user information in the database and display it in the DataGrid. I have done all the things I said above. What I want to do is to enter the name again. After submission, the first and second records found in the DataGrid are displayed, and so on ... What should I do?

What about the third and fourth time? This page will get bigger and bigger.

The implementation method is very simple, add the conditions of each query to viewstate, use or to write them to the sql condition when querying.

Record the "user name" of each query result in ViewState on the page, after each input of the user name, combine with the recorded user name and then query

Is it written like this:

this.ViewState ["卡号"] = this.CardNumberTextBox.Text;
using (CardAccess ca = new CardAccess ())
{
      cards = ca.GetCardByNumber (this.ViewState ["卡号"]);
}

But my Sql statement does not know how to write

shenmue024

this.ViewState ["卡号"] + = this.CardNumberTextBox.Text + ",";

Then use, divide into arrays. Then generate sql
