Question

我有一个带按钮的模板字段。我想按下按钮并获取行ID，以便我可以返回用户选择。我有一个常规选择按钮，工作正常，但用户希望非员工的人隐藏选择按钮。我有这个工作，但因为它是一个模板字段，它会触发RoW_command过程，我似乎无法获得行索引，因为它是一个模板字段而不是常规的Select按钮。或者我似乎无法命名常规选择按钮，因为它的命令字段没有名称或ID属性？

就像我说的那样，隐藏了名为btnSelect的模板字段 Private Sub GridView3_RowDataBound（ByVal sender As Object，ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs）处理GridView3.RowDataBound

    If e.Row.RowType = DataControlRowType.DataRow Then

        If (DataBinder.Eval(e.Row.DataItem, "LegacyPersonType") <> "Employee") Then
            e.Row.ForeColor = Drawing.Color.Black
            e.Row.BackColor = Drawing.Color.Yellow ' This will make row back color yellow 
            e.Row.FindControl("btnSelect").Visible = False

        Else
            e.Row.ForeColor = Drawing.Color.Black
            e.Row.BackColor = Drawing.Color.White   ' the normal employees make white
        End If

    End If

End Sub

当我按btnSelect
时，我需要找到Row索引 Private Sub GridView3_RowCommand（ByVal sender As Object，ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs）处理GridView3.RowCommand

    Dim index As Integer = Convert.ToInt32(e.CommandArgument) ‘ Error invalid

'换句话说，当按下模板字段时，没有e.CommandArgument '但点击常规选择

    Dim row As GridViewRow = GridView3.Rows(index)
    Session("EnterpriseID") = HttpUtility.HtmlDecode(GridView3.Rows(index).Cells(2).Text)
    Dim EmployeeType As String = HttpUtility.HtmlDecode(GridView3.Rows(index).Cells(7).Text)
    Dim CommonName As String = HttpUtility.HtmlDecode(GridView3.Rows(index).Cells(1).Text)

    Dim EnterpriseID = HttpUtility.HtmlDecode(GridView3.Rows(index).Cells(6).Text)

GridViewRow对象通过RowIndex事件中的RowCommand属性知道其行索引，如下所示：

Private Sub GridView3_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView3.RowCommand
    ' Get the row by finding the grandparent of the control (button) 
    ' that initiated the command
    Dim theGridViewRow As GridViewRow
    theGridViewRow = CType(CType(e.CommandSource, Button).Parent.Parent, GridViewRow)

    ' Get the index value from the grid view row
    Dim index As Integer = theGridViewRow.RowIndex
End Sub

好的我自己想通了，我在网格上的模板字段中创建了默认的选择按钮。因为它是默认按钮，所以它有必要的代码来激活它。这是从头开始创建模板字段的问题。通过使它成为模板字段，它还给它起了一个名字。因此，在RowDataBound代码中，当一个人不是员工时，上面的FindControl方法会隐藏它。 - R2 Builder 1分钟前编辑
