有什么方法可以使用 AutoGenerateColumns = true 操作 GridView 中的列? [英] Any way to manipulate the columns in GridView with AutoGenerateColumns = true?

问题描述

如果 AutoGenerateColumns = true，似乎无法操作 Gridview 的列.这是我的场景:

It seems like there's no way to manipulate the columns of a Gridview if AutoGenerateColumns = true. Here's my scenario:

我有一个通用的 GridView，它根据用户的选择显示各种不同的 LINQ 查询的结果.我喜欢 AutoGenerateColumns 的工作原理，而且我不必指定所有 BoundField、TemplateField 列等...

I've got a generic GridView that displays the results of various different LINQ queries depending upon what the user selects. I like the fact that the AutoGenerateColumns works like it should and I don't have to specify all the BoundField, TemplateField columns, etc...

除此之外，我还根据需要以编程方式添加其他列.以编程方式添加的列呈现在自动生成的列的左侧.如果我想将它们向右移动怎么办?

On top of that, I'm also programatically adding other columns as needed. The columns that are programatically added are rendered to the left of the autogenerated columns. What if I wanted to move them to the right?

GridView.Columns.Count 只计算那些编程的而不是自动生成的，所以我不能重新排列我想要的列.如有必要，我可以挂钩 RowDataBound 事件并隐藏"某些内容，但我无法重新排列.

GridView.Columns.Count only counts those that are programmed, not autogenerated, so I can't rearrange the columns I want around. I can hook the RowDataBound event and "hide" something if necessary, but I can't rearrange.

我是否只需要放弃 AutoGeneratedColumns=true，并为每个查询使用 BoundFields 布置它们?有什么我可以做的吗?

Do I just have to give up AutoGeneratedColumns=true, and lay them out with BoundFields for each query? Is there anything I can do?

推荐答案

你可以像这样操作数据绑定的东西:

You can manipulate things on data bound like this:

Private Sub MyGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Me.RowDataBound
  If Me.AutoGenerateColumns = True Then
    If e.Row.RowType = DataControlRowType.DataRow Then
          e.row.cells.add(some code here to add your special column)
    End If
    End If
End Sub

您必须创建自己的标题，但这是非常可行的.

You'd have to create your own header to but it's very doable.
