Choose the Recordset we have just created and set the parameters as required.
Important: the term “record” means the result item.
You can see a table based grid is inserted and now. Our result page is ready.
Now, we need to make our results to display only when we have some results. If no results we need to show the error message that which we created in the step2. Remember “datanotfound” div in step2.
Select the “datafound “ div and go to server behaviors panel click on the + symbol and go to “Show Region” and then click on the “Show Region If Recordset Is Not Empty”. Choose the recordset and press OK.
