Problem with addrow in grid Posts

December 16, 2013 at 4:07 pm Problem with addrow in grid #46608

Participant

Hi,

When I try to add a row with an id, I seem to lose the id when I click on the row. It show up the first time I click on it, but not after that.
I’m adding the row using var value = $(‘#TableDefinitionGrid’).jqxGrid(‘addrow’, guid(), {});
And on $(‘#TableDefinitionGrid’).on(‘rowselect’, function (event) {
TableFieldDefinitionID = event.args.row.TableFieldDefinitionID;
alert(TableFieldDefinitionID );
}

This shows me the ID, the first time I click on the row. But it becomes null after that.

Hi priyam.basu,

The ID passed when you call the “addrow” method is not stored in a variable defined by you. It is internally stored in the Grid and you can access it by calling “getrowid” method.

Hi Peter,

I had tried doing
var selectedrowindex = $(“#TableDefinitionGrid”).jqxGrid(‘getselectedrowindex’);
alert(selectedrowindex);
TableFieldDefinitionID = $(“#TableDefinitionGrid”).jqxGrid(‘getrowid’, selectedrowindex);
alert(“id: ” + TableFieldDefinitionID);

But this gives me the id of the previous selected row.

Hi priyam,

Please, find below a sample which illustrates how to do the following:

1. Add Row with Custom ID
2. Select the Row with the Custom ID
3. Get the New Row’s ID using “getrowid”
4. Result of method call – alert with text – ‘myID’

Hi Peter,

Thanks you for a quick response. If I want to send data through add row, I do so in JSON format. Does it matter if my JSON has extra information in it? Because it doesnt seem to be populating the data. It adds a blank row.
