Imports System.Data
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Page.IsPostBack = False Then
BindGrid()
End If
End Sub
Sub BindGrid()
Dim oDs As New DataSet
oDs.ReadXml(Request.PhysicalApplicationPath + "XMLFile.xml")
GridView1.DataSource = oDs
GridView1.DataBind()
End Sub
Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles GridView1.PageIndexChanging
GridView1.PageIndex = e.NewPageIndex
BindGrid()
End Sub
Protected Sub GridView1_RowCancelingEdit(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCancelEditEventArgs) Handles GridView1.RowCancelingEdit
GridView1.EditIndex = -1
BindGrid()
End Sub
Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
BindGrid()
Dim oDs As DataSet = GridView1.DataSource
oDs.Tables(0).Rows(GridView1.Rows(e.RowIndex).DataItemIndex).Delete()

Dim i As Integer = GridView1.Rows(e.RowIndex).DataItemIndex
Dim strId As String = CType(GridView1.Rows(e.RowIndex).Cells(2).Controls(0), TextBox).Text
Dim strName As String = CType(GridView1.Rows(e.RowIndex).Cells(3).Controls(0), TextBox).Text
Dim strTel As String = CType(GridView1.Rows(e.RowIndex).Cells(4).Controls(0), TextBox).Text

BindGrid()
Dim oDs As DataSet = GridView1.DataSource
oDs.Tables(0).Rows(i).Item(0) = strId
oDs.Tables(0).Rows(i).Item(1) = strName
oDs.Tables(0).Rows(i).Item(2) = strTel
oDs.WriteXml(Request.PhysicalApplicationPath + "XMLFile.xml")
BindGrid()
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
BindGrid()
Dim oDs As DataSet = GridView1.DataSource
Dim oDr As DataRow = oDs.Tables(0).NewRow
oDr("id") = txtId.Text
oDr("name") = txtName.Text
oDr("phone") = txtTel.Text
oDs.Tables(0).Rows.Add(oDr)
oDs.WriteXml(Request.PhysicalApplicationPath + "XMLFile.xml")
BindGrid()
End Sub
End Class
推荐答案
尝试以下代码.应该可以.
由 OriginalGriff
提供的上述链接转换后的代码中只有2个问题
1.在后面的代码中访问GridView行/单元格应使用方括号(即"[."])
2. GridView源应解析为DataSet. [我不确定它是否会起作用:(]
Try out below code. It should work.
Only 2 issues in code converted from above link provided by OriginalGriff
1. GridView row/cell accessing in code behind should be with square brackets(i.e. "[". "]")
2. GridView source should be parse to DataSet. [ I am not sure if it will work or not :( ]

希望对您有所帮助.
Hope it helps.
我不确定您的问题是什么,我看不到代码有什么大错误.
在VB和C#之间有一个在线转换器: http://www.developerfusion.com/tools/convert/vb-to-csharp/ [ ^ ]-我经常使用它!
I''m not sure what your problem is, I can''t see anything massively wrong with the code.
There is an on-line converter between VB and C# here: http://www.developerfusion.com/tools/convert/vb-to-csharp/[^] - I use it quite a bit!
