[Solved] How to stop row changed with radConfirm?

[Allin]

Hi,

I have some problems to stop RadGrid row change because radConfirm don't stop like command confirm to wait response.

I check if my row is dirty and if is the case, i want to radconfirm this row changed to advice user for lost of data not saved.

Script OnRowSelecting and OnRowSelected

function OnRowSelecting(sender, eventArgs) {
    return eventArgs.set_cancel(!confirm("Confirm navigation?"));
}

function OnRowSelected(sender, eventArgs) {
     // Make action...
}

with this script, OnRowSelected fired only if response is True from confirm, but with radConfirm OnRowSelected fired before response.

How can implement this with radConfirm?

Thank's

Hi Pat,

I have assembled a sample project showing the desired functionality implemented. The idea is to cancel the selecting event, show the rad confirmation and if OK is clicked select the row. The described implementation because the default browser confirm method stops the current code execution until you close the confirmation. However, the radconfirm function does not stop the thread and it is required to handle the callback function as shown below.

var isCurrentlySelecting = false;
function RowSelecting(sender, args)
{
    if (isCurrentlySelecting) return;
    var dataItem = args.get_gridDataItem();
    args.set_cancel(true);
    radconfirm("Are you sure you want to select the item?", function (result)
    {
        if (result)
        {
            isCurrentlySelecting = true;
            dataItem.set_selected(true);
            isCurrentlySelecting = false;
        }
    });
}

function RowSelected(sender, args)
{

}
