Question

我正在使用PagedDataSource To Paginate Repeater并且它工作正常但有一种方法可以突出显示所选页码或使其变为粗体。我尝试了css，itemcommand和click事件，但没有运气。

提前致谢

<asp:Repeater ID="repeaterPager" runat="server" OnItemCommand="repeaterPager_ItemCommand">
      <ItemTemplate>
        <asp:LinkButton  CssClass="sayfaNo" ID="btnPage" CommandName="Page" CommandArgument="<%#Container.DataItem %>" runat="server">
<%# Container.DataItem %></asp:LinkButton>
      </ItemTemplate>
    </asp:Repeater>

CodeBehind：

  private void MakeleleriGetir()
        {
          SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[0].ConnectionString);
          SqlDataAdapter da = new SqlDataAdapter("SELECT p.PostID,p.Title,p.DateTime,p.PostShort,p.CategoryID,i.SmallFileName,c.CategoryName From Posts as p inner join Resimler as i ON p.PostID = i.PostID inner join Categories as c On p.CategoryID = c.CategoryID", cnn);

          DataTable dt = new DataTable();
          da.Fill(dt);

          PagedDataSource pds = new PagedDataSource();
          pds.DataSource = dt.DefaultView;
          pds.AllowPaging = true;
          pds.PageSize = 4;
          pds.CurrentPageIndex = CurrentPage;

          PageCount = pds.PageCount;

          btnPrevious.Enabled = !pds.IsFirstPage;
          btnNext.Enabled = !pds.IsLastPage;

          if (pds.PageCount > 1)
          {
            repeaterPager.Visible = true;
            ArrayList pages = new ArrayList();
            for (int i = 0; i < pds.PageCount; i++)
            {
              {
                pages.Add((i + 1).ToString());

              }
            }

            repeaterPager.DataSource = pages;
            repeaterPager.DataBind();
          }
          else
          {
            repeaterPager.Visible = false;

          }
          RepeaterPosts.DataSource = pds;
          RepeaterPosts.DataBind();
        }
 protected int CurrentPage
    {
      get
      { // look for current page in ViewState

        object o = this.ViewState["_CurrentPage"];

        if (o == null)
        {
          return 0;   // default to showing the first page
        }

        else
        {
          return (int)o;
        }

      }

      set
      {
        this.ViewState["_CurrentPage"] = value;
      }
    }

    public int PageCount
    {
      get
      {
        if (ViewState["_PageCount"] != null)
          return Convert.ToInt32(ViewState["_PageCount"]);
        else
          return 0;
      }
      set
      {
        ViewState["_PageCount"] = value;
      }

    }

    protected override void OnInit(EventArgs e)
    {
      base.OnInit(e);
      repeaterPager.ItemCommand += new RepeaterCommandEventHandler(repeaterPager_ItemCommand);
    }


    protected void repeaterPager_ItemCommand(object source, RepeaterCommandEventArgs e)
    {

      CurrentPage = Convert.ToInt32(e.CommandArgument) - 1;
      MakeleleriGetir();

    }

    protected override void OnLoad(EventArgs e)
    {
      base.OnLoad(e);

      MakeleleriGetir();
    }

    protected void btnNext_Click(object sender, EventArgs e)
    {
      CurrentPage += 1;
      MakeleleriGetir();
    }

    protected void btnPrevious_Click(object sender, EventArgs e)
    {
      CurrentPage -= 1;
      MakeleleriGetir();
    }

  }
}

Answer 1

逻辑：使用ItemDataBound事件并将currentpage与btnPage的当前值进行比较。您可以使用FindControl获取当前的btnPage值。

希望有所帮助！

Answer 2

 protected void repeaterPager_ItemDataBound(object sender, RepeaterItemEventArgs e)
{

    //Enabled False for current selected Page index
    LinkButton lnkPage = (LinkButton)e.Item.FindControl("btnPage");
    if (lnkPage.CommandArgument.ToString() == (CurrentPage+1).ToString())
    {
        lnkPage.Enabled = false;
        lnkPage.BackColor = System.Drawing.Color.FromName("#FFCC01");
    }

}
