Does anyone know that if a record can be added through the Grid Control(Active or JS).
For example:
There is an add button and the grid will add a new blank row when I click it.

Hi Elaine,
For the most part the grid only displays how ever many rows are in the stack bound to it. If you would like to have empty rows for input, add extra rows to the stack. For example, if STK is bound to the grid then:
COMPUTE STK.FOCCOUNT = 10;
Would place 10 rows in the stack. If you wanted to press a button to add a blank line you could have:
COMPUTE STK.FOCCOUNT=STK.FOCCOUNT+1;
That would add the blank row to the bottom of the grid. You could then sort the stack if you wanted the blank row on the top.

FOCCOUNT is the number of rows in the stack. So, adding to that value will add extra rows.

Thanks,Mark.It works and I found another way to add a blank row by javascript.
  
function OnAddRecordBtn_Click ( )  {
var obj = document.getElementsByName('Grid1');
var table = obj[0];
table.insertRow(0);
}

A blank row will be added on the top of the grid. But I don't know how to insert the new value into the database. I'm not queit understand about the stack. But I think it is also possible in this way,right?

I am actually getting an error with that code. I am concerned that even though you CAN enter data into a blank row, that it may not get back to the application.

Stacks are VERY important to understand in Maintain. We use them to load data from the database and display that data on the form. A Grid displays the Database (or computed) fields as columns and data from the database on the rows. When you add / edit data into the grid, it goes into the stack and therefore back to the database.

Please review the help file on NEXT for loading the stack and concepts like FOCINDEX and FOCCOUNT.
