创建具有列在运行时所产生的GridView [英] Creating a GridView with columns generated at runtime

问题描述

我所在的列编程方式在运行时所产生的DataTable。我然后绑定这个数据表到一个GridView。我不知道是我怎么可以创建，以适应这种GridView控件，如果它是不可能的，我怎么能输出的DataTable成格式良好的HTML。

I have a DataTable where the columns are generated programmatically at runtime. I then bind this DataTable to a GridView. What I'm wondering is how I can create the GridView to accommodate this, and if it's not possible, how I can output the DataTable into nicely formatted HTML.

推荐答案

GridView控件有一个<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.autogeneratecolumns.aspx\"相对=nofollow> AutogenerateColums - 属性用于此目的。
你也可以动态生成列，例如：

The GridView has an AutogenerateColums-property for this purpose. You could also generate the Columns on the fly, for example:

VB.NET

Dim tbl As New DataTable
tbl.Columns.Add("ID", GetType(Int32))
tbl.Columns.Add("Name", GetType(String))
tbl.Columns.Add("Birthday", GetType(Date))
Dim pers As DataRow = tbl.NewRow
pers("ID") = 1
pers("Name") = "Tim"
pers("Birthday") = New Date(1973, 6, 9)

使用的AutoGenerateColumns 让网格生成列本身：

use AutoGenerateColumns to let grid generate the column itself:

Me.GridView1.AutoGenerateColumns = True
Me.GridView1.DataSource = tbl
Me.GridView1.DataBind()

或动态生成的列

For Each col As DataColumn In tbl.Columns
    Dim field As New BoundField
    field.DataField = col.ColumnName
    field.HeaderText = col.ColumnName
    GridView1.Columns.Add(field)
Next

C＃

foreach (DataColumn col in dt.Columns)
{    
    BoundField field = new BoundField();
    field.DataField = col.ColumnName;
    field.HeaderText = col.ColumnName;
    GridView1.Columns.Add(field);
}
