I've been looking, but can't seem to find a solution that is compatible with the latest version of ExtJs (this question is similar, but doesn't have a working/current solution). This is what I have so far, but it's a single select: new Ext.FormPanel({ labelAlign: 'top', frame: true, width: 800, items: [{ layout: 'column', items:[{ columnWidth: 1, layout: 'form', items: [{ xtype: 'combo', fieldLabel: 'Countries

问题 So I like the custom multi select control that jquery-mobile has and want to use it. So please don't suggest put data-role="none".

For some reason, it is becoming unresponsive on the ipad, but works fine on the

问题 I'm trying to mimic the way Windows Explorer handles multiple selection. In a default DataGridView, you can select multiple items using Ctrl-click. But if you release the Ctrl key and then try and drag/drop the selected items, it clears the selected items and only selects the "hit" row. I found the following solution somewhere online. protected override OnMouseDown(MouseEventArgs e) { int hitRowIndex = HitTest(e.X, e.Y).RowIndex; if(!SelectedRows.Contains(Rows[hitRowIndex])) { base
