Grid column Sort Ascending event issue

[Strikers]

When I clicked on column Sort Ascending event then my server side event called after 2-3 seconds and then I can see event mask on screen.
1. I don't know why it is happening
2. Is there any event at client side where I can change mouse pointer to wait mode when clicked on Sort Ascending and after sorting done back to Default ?

Client Side Code

 <DirectEvents>
                            <SortChange OnEvent="ColumnModel_SortChange">
                                <ExtraParams>
                                    <ext:Parameter Name="columnId" Value="column.dataIndex" Mode="Raw" />
                                    <ext:Parameter Name="direction" Value="direction" Mode="Raw" />
                                </ExtraParams>
                                <EventMask ShowMask="true"></EventMask>
                            </SortChange>

                        </DirectEvents>

Server Side Code

protected void ColumnModel_SortChange(object sender, Ext.Net.DirectEventArgs e)
        {
            string a = e.ExtraParams["columnId"];
            string b = e.ExtraParams["direction"];
            if (SortColumnsChanged != null)
            {
                this.extGrdBalances.SortedColumn = a;
                ExtSortColumnsChanged(this, new ExtSortColumnsChangedEventArgs(a, b));
            }
            // Call the unload so that persist fields are saved to storage.

            OnUnload(new EventArgs());
        }

Hello Striker!

I think that the way you developed your server-side sort handler you are just performing local sort and then calling the remote sort handler.

Take a look on this example, it is probably a good example of remote sorting: GridPanel's Paging and Sorting - Direct Method.

As for changing your cursor to an hourglass, provided you want to do so while the mask is shown (and then you mask the area you want the hourglass is shown), you'd probably want to do this CSS override:

.x-masked {
 cursor: 'wait'
}

I hope this helps!
