如何在空白宽度的Radgrid列上设置最小宽度

我有一个RadGrid，它在PageLoad期间以编程方式添加了列。对于我的网页，总会有至少一个空白宽的列（HeaderStyle.Width = Unit.Empty），其余列使用特定的像素宽度。所有列都可以调整大小。（在我的应用程序中，我们检索并在数据库中保存这些宽度）网格是可滚动的，所以如果它们超出网格的极限，用户可以滚动而不调整网格本身的大小。如何在空白宽度的Radgrid列上设置最小宽度

我遇到的问题是，当用户调整浏览器窗口的大小时，空白列最终会减少到0宽度（因为它们占用了“剩余空间”。有任何方法可以让我将自动调整大小限制为100px，以保证列可见？

至少一列必须为空或百分比宽度，否则RadGrid将默认为全部列的百分比宽度，从而取消我的特定像素宽度指定

我试过的一种方法是添加一个空白列填充空间的其余部分，因为它不会有问题，如果它是0宽度Howe这在调整其他列的大小时会导致问题。在这种情况下，应将空白列“消耗”到零宽度，然后开始扩展网格大小（或者在此情况下添加滚动条）。相反，它只是被推到一边，保持其宽度。我不知道这种方法是否可行，但我已经将它留在代码中，简单地取消它的注释。

这里是我的代码：

谢谢你的答复。此修补程序几乎是完美的，除了调整其他列之一时，未设置的列将捕捉到100个像素。有没有办法保持它的大小，直到它需要减少？ – 2013-04-30 20:24:22

你可以把条件放在这取决于值。请将此标记为答案或投票，如果它帮助你，谢谢 – 2013-05-01 10:26:58

没有为我工作。 – Dhananjay 2015-05-13 17:50:35
