我怎么一个TextBox列从code添加到一个GridView后面？

How do I add a TextBox column to a GridView from code behind?

推荐答案

使用一个TemplateField和一个TextBox添加到的ItemTemplate / EditItemTemplate里。

Use a TemplateField and add a TextBox to the ItemTemplate/EditItemTemplate.

<ItemTemplate> <asp:TextBox ID="TxtFirstName" runat="server" Text='<%# Bind("FirstName") %>'></asp:TextBox> </ItemTemplate>

您可以在ASPX绑定在上面还是在GridView.RowDataBound的例子：

You can bind it on the aspx as in the example above or in GridView.RowDataBound:

Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound Select Case e.Row.RowType Case DataControlRowType.DataRow Dim dr As DataRow = DirectCast(DirectCast(e.Row.DataItem, DataRowView).Row) Dim TxtFirstName As TextBox = DirectCast(e.Row.FindControl("TxtFirstName"), TextBox ) TxtFirstName.Text = dr("FirstName").ToString End Select End Sub

编辑：这是一个关于如何动态地添加一个TemplateField一个简单的例子：

Here is a simple example on how to add a TemplateField dynamically:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load If Not IsPostBack Then Dim txtColumn As New TemplateField txtColumn.ItemTemplate = New TextColumn Me.GridView1.Columns.Add(txtColumn) End If End Sub Class TextColumn Implements ITemplate Public Sub InstantiateIn(ByVal container As System.Web.UI.Control) Implements System.Web.UI.ITemplate.InstantiateIn Dim txt As New TextBox txt.ID = "MyTextBox" container.Controls.Add(txt) End Sub End Class
