Hi guys, I am trying to update a check box field in my grid by using a button clicked method.
How should I do it?

Thank you Leandro, This is the answer I need.
Hi,
I guess the problem is in markAllLoadedRecords(). It seems records in a grid are progressively loaded (retrieved from database) as you scroll it.
Instead of markAllLoadedRecords, try this:
<Table> record;
for (record = <dataSource>_ds.getFirst(); record; record = <dataSource>_ds.getNext())
{
...
}
<dataSource>_ds.research(true);
If your code isn't dependant on filters set on the datasource, You can update the table directly with a while select forupdate.
You could also retrieve the query from <datasource>_ds.queryRun() and retrieve the records with it. This will work similarly to the code I posted above.
Regards,
Hi Steeve,
Below is my code:
void clicked()
{
int i;
xinit_CustomerDet custdet;
;
super();
xinit_CustomerDet_ds.markAllLoadedRecords(1);
custdet = xinit_CustomerDet_ds.getFirst(true);
while (custdet)
{
custdet.Active = NoYes::Yes;
custdet.write();
custdet = xinit_CustomerDet_ds.getNext();
}
xinit_CustomerDet_ds.research(true);
}
I can updated the record but it did not updated all. In my grid, i have over 100 records, it always updated until half of it. And i have to click again button to trigger the function and update. Is there any solution to solve this?
In addition to Steeve's guidance, you can use <datasourcename>_ds.research() only once at the end of the process to update the display of all modified records.
Regards,
Use <datasourcename>_ds.getFirst() and <datasourcename>_ds.getNext() to browse the record. Modify each record and call write() so save the change. You will maybe need to call <datasourcename>_ds.refresh too see the change on the form.
Hi Pvanstilpelen,
I only can updated the first record. How about if I have 10 records in the grid view?
I am using "<datasourcename>.<fieldname> = NoYes::Yes" this code.
If your checkbox is bound to a datafield you can put following code in your clicked method
<datasourcename>.<fieldname> = NoYes::Yes
If it is not bound to a datafield and the name of your checkbox column is for instance ValueChecked put following code in your clicked method on the button
ValueChecked.Value(1);
In the properties of the ValueChecked checkbox, set AutoDeclaration to YES to be able to use it in the coding.
