gridview的突出当前行 [英] gridview highlighting current row

问题描述

有突出在一个gridview当前所选行的一个内置的方法？

Is there a built-in method of highlighting the currently selected row in a gridview?

在我的GridView的每一行都有一个按钮（通过ButtonField字段）。当用户presses此按钮，背景颜色的变化......我这样做是这样的：

Each row in my gridview has a button (via a buttonField). When the user presses this button, the background color changes...I do it like this:

Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand
    If e.CommandName = "Select" Then
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Dim selectedRow As GridViewRow = gvTransferOwner.Rows(index)
        selectedRow.Style.Add("background-color", "#ffcccc")
    End If
End Sub

这凸显了该行，但是一旦用户presses另一行的按钮，它仍然保留了所有的previously- pressed行的颜色。

This highlights the row, but once the user presses the button in another row, it still retains that color in all previously-pressed rows.

有没有一种方法，以便只有一次行（当前所选行）突出显示？

Is there a way so that only one row at a time(the currently selected row) is highlighted?

感谢

推荐答案

如果您使用全局变量来存储被选定行的索引，您可以更改该行回原来的颜色每当一个新行选中。

If you use a global variable to store the index of the row that is being selected, you can change that row back to the original color whenever a new row is selected.

Dim previousSelected As Integer 'global variable to store the last selected index
Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand
    If e.CommandName = "Select" Then
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Dim selectedRow As GridViewRow = gvTransferOwner.Rows(previousSelected)
        selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color
        selectedRow = gvTransferOwner.Rows(index)
        selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row
        previousSelected = index
    End If
End Sub
