将背景颜色更改为行网格

问题描述：

我有一个网格视图，我想要点击哪一行将其背景颜色更改为红色。但我有一个问题，我点击一行，颜色变为红色，然后当我点击一个不同的行时，它也改变了它的背面颜色，但预览一个保持红色。我希望唯一选择的行为红色。

我的代码如下：

I have a grid view, and I want that which row i click to change its background color to red. but I have a problem, i click a row and the color changes to red, then when i click a different row it also changes its back color but the previews one stays red. I want that the only selected row to be red.
my code looks like this:

i = MyGrd.SelectedCells(0).RowIndex
MyGrd.Rows(i).DefaultCellStyle.BackColor = Color.Red

参考 - 如何更改（设置）GRIDVIEW在ASP.NET中选择的行颜色 [ ^ ]

你可以轻松更改 SlectedIndexChanged 内的行背景颜色，如下所示。

Refer- HOW TO CHANGE ( SET ) GRIDVIEW SELECTED ROW COLOR IN ASP.NET[^]

You can easily change the Row Background colour inside SlectedIndexChanged Event like below.

Protected Sub OnSelectedIndexChanged(sender As Object, e As EventArgs)
    For Each row As GridViewRow In GridView1.Rows
        If row.RowIndex = GridView1.SelectedIndex Then
            row.BackColor = ColorTranslator.FromHtml("#A1DCF2")
        Else
            row.BackColor = ColorTranslator.FromHtml("#FFFFFF")
        End If
    Next
End Sub
