DevExpress如何实现对报表中双向表数据的动态绑定???
- 环境:为framework4.5.2 WPF框架 Dev为最新版本 数据来源为List(随报表预览界面一并生成,动态数据)
- 目的:现欲利用DevExpress的报表控件生成并展示横纵坐标都为动态的双向表格,且数据是随预览界面一起生成list(非静态)
- 现状:根据官方视频演示，对EF与SQL的数据都可以正常生成双向表 但是绑定数据源为未赋值的Ｌｉｓｔ并在程序启动并赋值时 报表便会报错 且每次报错位置都不唯一
- 问题如上 是在是解决无能 还请大神赐教
上图为报错其一
上图为赋值方法
InitializeComponent()代码如下

/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

把你的InitializeComponent代码贴出来
出现堆栈溢出错误的原因是，在这个方法里出现了无限递归
也就是函数A调用了B，而B又调用了A，导致无限循环了。
