Question

How can I make the SelectCommand use a textbox from the default page so that I can add that to the where clause? Please include an example I am new to programming and it helps me understand the concept better. thanks in advance.

Example WHERE (BADGE = 10000 +
xBadgeTextBox.Text)?

string Badge = "100000" + Request.Form["xBadgeTextBox"];

 <asp:SqlDataSource ID="Time" runat="server" 
         ConnectionString="<%$ ConnectionStrings:Time %>" 
         ProviderName="<%$ ConnectionStrings:Time.ProviderName %>" 
         SelectCommand="SELECT CLOCK_IN_TIME, CLOCK_OUT_TIME, BADGE FROM CLOCK_HISTORY WHERE (BADGE = 100000342)"> // use the badge number instead.
     </asp:SqlDataSource>

You’ll want to add parameters to the query and specify them within the SqlDataSource object. Take a look here:

Also, please PLEASE be very careful of SQL injection attacks here. At some point you may be tempted to just concatenate the string from the textbox to the select command. Don’t 🙂
