Question

在我的用户控件中，我有gridview，这个网格是使用Itemplate以编程方式创建的。在InstantiateIn方法中，我有这段代码。

Select Case _templateType
      Case ListItemType.Header
          Dim linkButton As New LinkButton
          linkButton.Text = "Delete"
          linkButton.CommandName = "Click"
          linkButton.CommandArgument = Me._columnID

          container.Controls.Add(linkButton)

我想将Click事件连接到此LinkButton，并在代码后面使用此事件。这是GridViewTemplate的构造函数如何实现ITemplate

Public Sub New(ByVal type As ListItemType, ByVal colname As String, Optional ByVal infoType As String = "")
    'Stores the template type.
    _templateType = type
    'Stores the column name.
    _columnName = colname

    _infoType = infoType

    _columnID = columID

  End Sub

我从用户控件那里得到了这个电话：

bfield.ItemTemplate = New GridViewTemplate(ListItemType.Item, dt.Columns(col).ColumnName, "label")

在哪里

Dim bfield As TemplateField = New TemplateField()

Answer 1

AddHandler linkbutton.Click, AddressOf X 'X being the method that handles the click event.

Answer 2

AddHandler linkButton.Click, AddressOf linkButton_Click

Sub linkButton_Click(ByVal sender As System.Object, ByVal e As EventArgs)
   ' here is your click handler
End Sub

ITemplate和linkbutton点击事件
