Hi,

Grateful if I can be advised the methods of getting the number of columns of a grid by
1) javascript in dynaform and
2) php in trigger.

Thousand Thanks.

cheers,

Hello Karl,

Long time no see you in here....
Since there is no getNumberColumns() function for Grid, meant you need to write your own function.

Give you some hints on JS to do that:
1/ var gValues = $("#grid_id").getValue(); //get all values
2/var columns = gValues[0].length;

For trigger:
you could pass your columns to a hidden_variable or case variables
At trigger, retrieve back the hidden_var or case_var

Good luck , better try it, cheers.

Hi Kirk,

How are you?
Yes, haven't post message here for some time, especially after the departure of Amos.

Thank you for your advice. I'll try them.

those 2 JS lines is working even when the grid is with one empty row .
Not working when the grid is clear, i.e. no rows at all.

Hi Kirk,

Thx for your kind attention.

Hi,

Accidentally, in https://www.pmusers.com/index.php/Copy_Grid, I found the following codes can also obtain the number of columns of a grid.

var aCols = $('#gridID').getInfo().columns;
var gColNo = aCols.length;

cheers,
