Question

我有RowDataBound gridview查找哪一年处于活动状态，现在它有一个并且突出显示。但是，让我说我想让另一年活跃，一个仍然突出显示，你点击的那个也突出显示。但我想要

VB：

Protected Sub grdFinYear_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdFinYear.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then

        If grdFinYear.DataKeys(e.Row.RowIndex).Values("FIN_ID") = FIN_ID Then
            Dim activeButton As Button = e.Row.FindControl("btnSelect")
            activeButton.CssClass = "ActionButtonsActiveYear"
            e.Row.BackColor = Color.FromArgb(0, 121, 139, 169)
        Else
            Dim makeActiveButton As Button = e.Row.FindControl("btnSelect")
            makeActiveButton.CssClass = "ActionButtonsMakeThisYearActive"
        End If
    End If
    End Sub

欢迎使用C＃或vb帮助，所以我认为它必须像selectedindexchange一样使用。但是这个SUB一半没用，不是吗？

试图完全理解....但我认为当年份改变时你需要做什么，你需要重新绑定网格，这将运行你的rowdatabound代码并改变亮点。

没有看到你的所有代码，很难说......但是在页面加载时你设置FIN年份（仅在不回发时才这样做）。

修改你的RowDataBound代码，将一些CommandName和CommandArgument属性添加到btnSelect，就像这样......

Protected Sub grdFinYear_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdFinYear.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then

    If grdFinYear.DataKeys(e.Row.RowIndex).Values("FIN_ID") = FIN_ID Then
        Dim activeButton As Button = e.Row.FindControl("btnSelect")
        activeButton.CssClass = "ActionButtonsActiveYear"
        activeButton.CommandName = "ActiveButton"
        activeButton.CommandArgument = **Bind to Year for this row**
        e.Row.BackColor = Color.FromArgb(0, 121, 139, 169)
    Else
        Dim makeActiveButton As Button = e.Row.FindControl("btnSelect")
        makeActiveButton.CssClass = "ActionButtonsMakeThisYearActive"
        makeActiveButton.CommandName = "MakeActiveButton"
        makeActiveButton.CommandArgument = **Bind to Year for this row**
    End If
End If
End Sub

然后在你的btnSelect.click事件的代码中......

Protected Sub btnSelect_Click(ByVal sender As Object, ByVal e as EventArgs) Handles btnSelect.Click
    If sender.CommandName = "MakeActiveButton" Then
        FIN = CInt(sender.CommandArgument)
        grdFIinYear.DataBind()
    End If
End Sub

希望能帮助
