将鼠标悬停在UWP中的按钮上时更改文本颜色

Question

我试图在鼠标悬停时修改Button的Text颜色，从黑色到另一种颜色，我使用了这个样式：

protected void Page_Load(object sender, EventArgs e)
        {
            if(!String.IsNullOrEmpty(Request.QueryString["srch"]))
            {
                String srch = Request.QueryString["srch"];
                search.Text = Request.QueryString["srch"];

                //perform search and display results
                String connString = System.Configuration.ConfigurationManager.ConnectionStrings["GroupsConnString"].ToString();

                conn = new MySql.Data.MySqlClient.MySqlConnection(connString);

                conn.Open();
                queryStr = "";
                queryStr = "SELECT g.*,CONCAT(firstname,' ',lastname) as name FROM app_groups.groups g LEFT JOIN users u ON u.id = g.id_user WHERE group_name LIKE '%" + srch + "%' OR group_type LIKE '%" + srch + "%'";
                cmd = new MySql.Data.MySqlClient.MySqlCommand(queryStr, conn);

                reader = cmd.ExecuteReader();
                gname = "";//group name
                gtype = "";//group type
                uname = "";//user name
                id = "";
                warning = "";
                id_owner = "";

                if (reader.HasRows)
                {
                    while (reader.HasRows && reader.Read())
                    {
                        uname = reader.GetString(reader.GetOrdinal("name"));
                        gname = reader.GetString(reader.GetOrdinal("group_name"));
                        gtype = reader.GetString(reader.GetOrdinal("group_type"));
                        id = reader.GetString(reader.GetOrdinal("id"));
                        id_owner = reader.GetString(reader.GetOrdinal("id_user"));
                        warning = reader.GetString(reader.GetOrdinal("warning"));

                        Panel pan = new Panel();
                        pan.CssClass = "col-sm-4 group";
                        if ((Session["uid"] != null && Session["uadmin"].Equals("1")) || id_owner.Equals(Session["uid"]))
                        {
                            adminCtrls = new Panel();
                            adminCtrls.CssClass = "adminCtrls";
                            btn = new Button();//delete group button for admins only
                            btn.Click += new EventHandler(deleteGroup);
                            btn.ID = "sterge";
                            btn.CssClass = "btn btn-danger btn-xs";
                            btn.Text = "Sterge grup";
                            btn.CommandArgument = id;
                            //btn.Attributes.Add("style", "float:right;");
                            adminCtrls.Controls.Add(btn);

                            if (Session["uadmin"].Equals("1"))
                            {
                                if (!warning.Equals("1"))
                                {
                                    btn = new Button();//warn owner button for admins only
                                    btn.Click += new EventHandler(warnOwner);
                                    btn.ID = "warn";
                                    btn.CssClass = "btn btn-warning btn-xs";
                                    btn.Text = "Avertizeaza owner grup";
                                    btn.CommandArgument = id;
                                    adminCtrls.Controls.Add(btn);
                                }
                                else
                                {
                                    btn = new Button();//warn owner button for admins only
                                    btn.ID = "warn";
                                    btn.Enabled = false;
                                    btn.CssClass = "btn btn-warning btn-xs";
                                    btn.Text = "A fost avertizat";
                                    adminCtrls.Controls.Add(btn);
                                }
                            }
                        }
                        if (adminCtrls != null)
                        {
                            pan.Controls.Add(adminCtrls);
                        }
                        pan.Controls.Add(new LiteralControl("<span class='title text-center'>" + gname + "</span><br/>"));
                        pan.Controls.Add(new LiteralControl("<span>Owner: <span class='owner'>" + uname + "</span></span><br/>"));
                        pan.Controls.Add(new LiteralControl("<span>Categorie: <span class='type'>" + gtype + "</span></span><br/>"));
                        groupsShow.Controls.Add(pan);
                    }
                }

                reader.Close();
                conn.Close();
            }
        }

但是这段代码的问题在于我得到悬停的结果（悬停时的颜色已经改变），但是按钮的文本没有显示在左中心，这就是结果：

这是我的代码，要在按钮上应用样式：

  <Style  x:Key="ButtonmenuStyle"
    TargetType="Button">
        <Setter Property="Foreground" Value="#393185"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal"/>
                                <VisualState x:Name="PointerOver">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" To="#393185" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="Content1" />
                                    </Storyboard>
                                </VisualState>
                                <VisualState x:Name="Pressed">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" To="#393185" Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="Content1" />
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Grid>
                            <ContentPresenter x:Name="Content1"/>
                        </Grid>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

请如何更正我的代码，让文本以Left为中心 谢谢你的帮助

如果要求垂直居中按钮内容，可以执行以下操作：

<ContentPresenter x:Name="Content1" VerticalAlignment="Center"/>
