Getting value from a cell from a gridview on RowDataBound event

阅读更多关于 Getting value from a cell from a gridview on RowDataBound event

问题 string percentage = e.Row.Cells[7].Text; I am trying to do some dynamic stuff with my GridView, so I have wired up some code to the RowDataBound event. I am trying to get the value from a particular cell, which is a TemplateField. But the code above always seems to be returning an empty string. Any ideas?

Asp.net 实现GridView分页时记录CheckBox状态

阅读更多关于 Asp.net 实现GridView分页时记录CheckBox状态

用GridView自带的方法实现分页功能。用ViewState记录GridView分页后各个分页面的CheckBox的选中状态。 GridView不同分页面之间的跳转只是刷新当前页面，并没有跳出当前Web页面的生命周期。(这也是ViewState的作用范围) 如果想要在不同Web页面之间跳转实现信息传递的话，可以用Cookie，Session等。当我们写Asp.net程序的时候避免不了的是从数据库中取数据，然后将这些数据显示在页面上，当数据非常多的时候我们又很自然的想到了把这些数据进行分页显示。分页在Asp.net中用到的地方是非常多的，我们可以自己去编写分页程序，也可以用Asp.net给我们封装好的。这里我们用Asp.net封装好的分页功能，并用ViewState实现实现不同分页面的CheckBox的状态：用GridView去显示数据的时候避免不了的与CheckBox的结合（即：将GridView的每一行的第一列设置为CheckBox）方法如下：可以用拖控件的方法去创建GridView然后在GridView控件中加入CheckBox列。body的代码如下：其中onpageindexchanging="GridView1_PageIndexChanging"表示选择不同分页面时所调用的方法，AllowPaging="True"表示此GridView允许自带的分页

问题 Is there a way in ASP.NET to have a "floating" header, much like a header you would see in an Excel sheet that follows you down the page as you scroll? Or alternatively, an easier route may be to have the header appear after every line, for example: Header 1 | Header 2 | Header 3 val 1 | val 2 | val 3 Header 1 | Header 2 | Header 3 val 4 | val 5 | val 6 Can either of the above options be done? I get the feeling either route is going to take some javascript wizardry. 回答1: I was in the same

阅读更多关于 prevent wpf listview header double click autosizes column

This causes a problem for me because my column header width is no longer in sync with the width of the columns in my row templates. Is there a
