用户界面控件的王者之争：Kendo UI vs DevExpress（一）

由 泄露秘密 提交于 2019-12-16 11:03:24
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 在一次使用ASP.NET MVC进行开发的Web项目中，我们需要 用户界面控件 来帮助实现界面的大部分功能。由于项目比较复杂，我们最终确定对 Kendo UI 和 DevExpress 这两款国际知名的用户界面组件进行评估。下面笔者跟大家分享一下评估控件的经验，希望对其他选购控件的朋友提供一个参考和借鉴。 当时我们评估这两款控件主要考察：控件的功能、易用性、与当前项目的集成时间和自动代码完成的时间。 控件功能 首先我们比较了Kendo UI和DevExpress当前所提供的控件，并大致评估了控件的功能。根据项目的需求，我们主要测试了文本和日期两个控件。 Kendo UI Kendo UI是Telerik旗下的控件，在Web和移动开发领域都有非常棒的表现，在开发者当中也是相当的受欢迎。Kendo UI提供了两个文本字段控件： Autocomplete 和 NumericTextBox 。后面个控件提供了各种选项，比如价格、百分比、测量和质量。这些控件非常惊艳，功能很强大，不过唯一的不足就是它的Mask文本字段，比如输入邮件和地址必须要用固定的格式，不过这个问题用一个jQuery插件就可以轻松解决。 Kendo UI的文本字段有三个选项： Calendar, DatePicker 和 DateTimePicker

问题 I am having an issue with my comboBoxEdit in a gridcontrol. I am using Winforms Devepress 11.2. I clicked in the text of an existing Repository comboBoxEdit, and typed in "appear backwards", however, it displayed as "sdrawkcab raeppa" like it would in a mirror. There are some posts about this topic but none of the solutions seem to work The reason for this is the following foreach (GridColumn column in this.gvNotes.Columns) { var columnEdit = column.ColumnEdit; if (columnEdit != null) {

What I want is able to see the editor but it should

由 旧时模样 提交于 2019-12-13 19:34:08

When clicked on update of the particular row, a form pops down which contains all the columns of the grid. Now i want to set the readonly property of one of the columns to true, which i did by column.ReadOnly = true; But what this does is sets the column to readonly always i.e. even during New Click. Where as i want this readonly property only during edit click. here is my devexpress grid

Or
