关于Gridview_rowcommand使用的方法

在点击自定义的Button时引发的Gridview_rowcommand事件

首先需要做一下Gridview_rowcreated事件:

Protected   Sub GridView1_RowCreated() Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
        If (e.Row.RowType = DataControlRowType.DataRow) Then
            Dim bt1 As Button = CType(e.Row.FindControl("cart"), Button)
            bt1.CommandArgument = e.Row.RowIndex.ToString
            Dim bt2 As Button = CType(e.Row.FindControl("favorite"), Button)
            bt2.CommandArgument = e.Row.RowIndex.ToString
        End If

    End Sub

接着写Gridview_rowcommand事件:

If  e.CommandName  =   " cart "   Then
             Dim  index  As   Integer   =  Convert.ToInt32(e.CommandArgument.ToString().Trim())
             MsgBox (index)   // 取得当前的行号
             Dim  label1  As  Label  =   CType ( Me .GridView1.Rows(index).FindControl( " lblproid " ), Label)
             Dim  id  As   Integer   =   CType (label1.Text.ToString,  Integer )
             Dim  label2  As  Label  =   CType ( Me .GridView1.Rows(index).FindControl( " lblproname " ), Label)
             Dim  produtname  As   String   =  label2.Text.ToString
             Dim  price  As   Decimal   =   CDec ( Me .GridView1.Rows(index).Cells( 5 ).Text.ToString)
             // 以上各行为根据行号取得各栏们的值
         Else
             Dim  index  As   Integer   =  Convert.ToInt32(e.CommandArgument.ToString().Trim())
             Dim  label1  As  Label  =   CType ( Me .GridView1.Rows(index).FindControl( " lblproid " ), Label)
             Dim  id  As   Integer   =   CType (label1.Text.ToString,  Integer )
// 同上
         End   If

就这个问题,研究了好久呢,终于出来了!
