ExtJS 4 - How to display template having width greater than the width of combo-box?

由 自闭症网瘾萝莉.ら 提交于 2020-01-23 16:17:40
问题 I have a combo-box in which the values are being displayed in a template. Now, I want the width of the template to be more than that of combo-box and hence I am using matchFieldWidth:false as mentioned at the link - ExtJS ComboBox dropdown width wider than input box width? But when I do so, then in the list of values there is no scrollbar displayled due to which the user is able to see only the first two values. The complete list gets displayed as soon as matchFieldWidth:false is removed, but

I have a tree panel. Inside that tree panel I have a dockedItem of xtype: 'textfield'. That textfield takes a value and uses it as a parameter in an ajax request via Ext.Ajax.Request inside a handler for the specialkey event. The server returns a JSON object on its response that gets decoded and contains

由 牧云@^-^@ 提交于 2020-01-17 01:22:05
问题 I need to set an ajax request with a generated url.

ExtJS 4.1.0 grid performance issue

由 依然范特西╮ 提交于 2020-01-14 03:09:19
问题 I am using an ExtJS grid with 50 columns and more than 1000 records. I am facing performance issues while scrolling vertically/horizontally and for cell editing.
