Hi,

I am having an issue deleting records from my grid, which I am binding to an ObjectDataSource.

Code below:

function doDeleteRows() {

            var valid = true;
    
            var gridRows = grid.get_rows();
            var selectedRows = grid.get_behaviors().get_selection().get_selectedRows();

            // do we have any rows selected
            if (selectedRows.length == 0) {
                valid = false;
                displayPageTextMessage("You must select at least one row to delete.", true);
            }
            else {

                var confirmation;
                if (selectedRows._keys.length == 1) {
                    confirmation = "Are you sure you want to delete the selected line (1 record)?";
                }
                else {
                    confirmation = "Are you sure you want to delete the selected line (" + selectedRows._keys.length + " records)?";
                }

                valid = confirm(confirmation);
            }

            if (valid) {

                for (var i = selectedRows.get_length() - 1; i >= 0; i--) {
                    var row = selectedRows.getItem(i);
                    gridRows.remove(row);
                }

                displayPageTextMessage("Deleted succesfully.", true);
            }

            return false;
        }

                <asp:Parameter Name="account_line_id" Type="Int32" />                
            </DeleteParameters>

        </asp:ObjectDataSource>

I have a menu item on the page that calls doDeleteRows(). I get the error message selecting  one or multiple rows. The error says:

InvalidOperationException

ObjectDataSource 'odsAccountLineList' could not find a non-generic method 'DeleteAccountLine' that has parameters: fiscalYear, account_line_id, CSBALine.

However, I do have a method as such. In fact, I even created a method stub with the third parameter just to trick it as below:

<DataObjectMethod(DataObjectMethodType.Delete)>
    Public Shared Function DeleteAccountLine(ByVal fiscalYear As String, ByVal account_line_id As Integer, ByVal CSBALine As Integer) As Boolean
        ' delete the record
        CSBADAL.DeleteAccountLine(fiscalYear, account_line_id)

        Return True

    End Function

Your help is very appreciated.

P.S. what's the proper way to post code in tags on here?
