Title: Add a new Event
Post by: leela on February 09, 2015, 03:15:58 PM

Hi,

I want to add a new event to the datagrid like following, when singleSelect is true
onBeforeUnselectAll: function(unselectIndex){},

where I need to get the index of the record that just got unselected.

The OnUnSelect/onUncheck/onBeforeUnselect/onBeforeUncheck do not get fired in this case

I have added this code to the selectRow() in the jquery.easyui.all.js file

if (opts.singleSelect){
         var unselectIndex = opts.finder.getTr(target, '', 'selected').attr("datagrid-row-index");
         if(unselectIndex!=undefined && unselectIndex!=index){
            opts.onBeforeUnselectAll.call(target, unselectIndex);
         }
         unselectAll(target);
         selectedRows.splice(0, selectedRows.length);
      }

But want to know if there is a better way of doing it without modifying the library itself.
Like just extend the datagrid API and add new events.

Appreciate any help

If you only want to get the row to be selected, please try the 'onBeforeSelect' instead.

Code:

$('#dg').datagrid({
    onBeforeSelect: function(index,row){
        var selected = $(this).datagrid('getSelected');
        if (selected && selected != row){
            console.log(selected)
        }
    }
})

Hi,

I am not trying to get the row to be selected.
I am trying to get the row that will be unselected, when you select a row.

Basically I have a Datagrid, with singleSelect option.
Let us assume there are 3 rows. I selected row 2 (index - 1).
Now when I select row 3(index - 2), row 2 gets unselected because of singleSelect:true option.
I need to get the index of the row 2 that gets unselected, when I select row3.

I expected onUnSelect to work, but looks like the onUnSelectAll is being triggered instead, because of singleSelect option
So I need to get the index of all the records(basically only one record) that will be selected, before actually selecting the record clicked by User.

Hope I conveyed my requirement clearly.

Please let me know if you have any suggestions

Please look at this example http://jsfiddle.net/zLobksxz/. You can get the unselected row before selecting a new row.
