Question

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">

   <ItemTemplate>              
   <asp:Button ID="Button2" runat="server"  CommandName="SaveId" CommandArgument='<%#Eval("subid") %>' OnClick="lnkSubject_CLick" Text='<%#Eval("subject") %>' />
   </ItemTemplate>

</asp:Repeater>

我需要更改用户点击的转发器内的按钮的前景色。当用户单击不同的按钮时，所有单击的按钮都保持蓝色。我只希望当前点击的按钮保持蓝色。

protected void lnkSubject_CLick(object sender, EventArgs e)
{

    Button Button2 = (Button)sender;

    Button2.ForeColor = System.Drawing.Color.Blue;
    Button2.BackColor = System.Drawing.Color.White;
    Button2.BorderColor = System.Drawing.Color.Blue;

}

试试这个： -

protected void lnkSubject_CLick(object sender, EventArgs e)
{
    Button Button2 = (Button)sender;
    foreach (RepeaterItem item in Repeater1.Items)
    {
        Button otherButton = (Button)item.FindControl("Button2");
        if (otherButton.ForeColor != Color.Empty )
        {
            otherButton.ForeColor = Color.Empty;
            otherButton.BackColor = Color.Empty;
            otherButton.BorderColor = Color.Empty;
        }
     }
     Button2.ForeColor = Color.Blue;
     Button2.BackColor = Color.White;
     Button2.BorderColor = Color.Blue;
}

在这里，我只检查ForeColor属性，如果你想也可以检查其他属性。
