How to manually perform an Ajax callback to a xBasic function

[WindForce]

Hi
In the onClick of a button, i would like to prompt for confirmation prior to running an Ajax callback to a xBasic function.
So, i thought of using the A5.msgBox.show function to prompt for the confirmation, then if button "Yes" is pressed, i would like to call the xBasic function. How do i perform that callback?

Thanks
Jaime

Hey,

Start by adding an Action Javascript callback (A5 will define the JS code for you).

Then go to its source code and add in this js:

if (confirm('Are you sure?')) {
// place the ajax callback code here
}

Cheers,
Andy

Was just doing one of those...

var answer = confirm('Is it OK to remove the attachment from this vendor?');
if(answer == true) {
	{grid.Object}.ajaxCallback('G',{Grid.RowNumber},'ClearAttachment','','_getData=true');
} else {
	alert('The attachment will NOT be removed per your request.');
}

Works as advised. Now i have a new problem related to this: this grid is not editable, so my e._currentRowDataNew is empty. How can i still have access to the fields in the grid from my function?

I quite often use this method on a non-editable grid and am able to use e._currentRowDataNew so I'm not sure what is happening on yours.
I begin my function with: function functionName as c (e as p)
Is that what you're doing?

Of course. I know that the _getData=true part is there so the current row data goes through, but for some reason, when i stop the execution, i can see e._currentRowDataNew is empty :-(

that will take someone with a higher level of savvy than me to explain, Jaime

Jaime,

Be sure that you choose a primary key in the AlphaDAO query. This is required to submit data to the callback if the grid is read-only.

Re: How to manually perform an Ajax callback to a xBasic function

Frank is very correct - no primary key set can mean that no values are passed. Unless of course you make the grid editable and make your primary keys into hidden textboxes. Then these get passed anyway.
BTW it has always frustrated me that A5 cannot determine primary keys from MS Access views (internally-defined queries). Any time you edit the query, you lose the PK settings and must manually reset them!!! Bug or SQL limitation?

I think that's it, this grid is based on a view...Will investigate this, but i really hope i don't have to make it editable...

You don't have to make it editable. Just include and choose a primary key. It can be any field, however you want it to uniquely identify the data.

Thanks for this simple javascript way to ask for confirmation, was looking at more complicated options, so this was brilliant.

Proves the msgboard works even on messages from years ago!
