How to set fields value in every line of a grid through x++?

(0) ShareShare
ReportReport
Posted on by bjdchw 75

I want to set the field value of the grid which is related to the data source. I use the datasource_ds.getFirst() and datasource_ds.getNext to retrieve all of the records, and then set the value of each field. After the loop, I use datasource_ds.refreshEx(-1) to refresh the grid, but only the first line is changed.

My code is as below:

SalesLine salesLine;

salesLine = SalesLine_ds.getFirst();
while (salesLine)
{
    salesLine.QtyOrdered = 20;
    salesLine = SalesLine_ds.getNext(); 
}
SalesLine_ds.refreshEx(-1);

How can I set value of all lines?

    Hi bjdchw!

    This method works only with selected rows. If you want to update all rows in the grid without selecting you should use queryRun of ds query.

        QueryRun    qr = new QueryRun(SalesLine_ds.query());
    SalesLine   salesLineLocal;
    
    ttsBegin;
    while (qr.next())
    {
        salesLineLocal = qr.get(tableNum(SalesLine));
        salesLineLocal.selectForUpdate(true);
        salesLineLocal.QtyOrdered = 20; 
        salesLineLocal.update();
    }
    ttsCommit;
    
    SalesLine_ds.executeQuery();

    Hi Rustem Galiamov,

    Thank you for your reply. I only want to update all the value in the screen. It means I don't want to save the new value to the table right now. Do you have any ideas?

    Hmm. What do you mean "I don't want to save the new value to the table right now" ?

    The rows what you may see on the grid, it's a current query of DS. You can add ranges, filters and use query as well.

    The record in the grid is saved when focus is removed from that line. So you can't assign values to multiple lines without saving.

    If you share your business requirement, maybe we can help you find another solution.

    My business requirement is that update the grid in a button event, but not save to db until click the save button.

    Maybe tempDB is a good solution.

    In this case a temp table is a good solution. You will first save the values in your temp table, and when the user clicks Save, the values will be written in the actual table.

    And another fields must be changed also. LineAmount as example. Just keep it in mind...
