css – SPGridView中的冻结(锁定)列

CSS 2019-05-08
我在SPGridView中看到了许多冻结列的例子,但我不知道为什么它们都不适用于我.我的意思是 – 没有冻结.

我将很感激地看一下我的代码.

下面是准备启动的代码片段.它必须适用于IE 8(其他浏览器无关紧要).

我将提供100分的解决方案,这将有效.

解决方法

您面临的问题(基于您链接的示例站点)是Web上的“工作版本”仅在Quirks模式下工作,但如果您在Master上强制执行,则您的SharePoint 2010页面甚至不会在Quirks模式下打开页.

如果你能够使用jQuery,你可以轻松地创建第一列的副本(如果你想要第一列),我会玩一些代码并稍后编辑它.

编辑w /解决方案：http://jsfiddle.net/q48dS/

EDIT2：在您的Visual Web部件上：

<div id="container">
<SharePoint:SPGridView runat="server" DataSource="<%# Items %>" ShowHeader="true"
    AutoGenerateColumns="False" ID="tbl" Visible="false">
    <Columns>
      <asp:BoundField datafield="Column0" HeaderText="Column0" />
      <asp:BoundField datafield="Column1" HeaderText="Column1" />
      <asp:BoundField datafield="Column2" HeaderText="Column2" />
      <asp:BoundField datafield="Column3" HeaderText="Column3" />
      <asp:BoundField datafield="Column4" HeaderText="Column4" />
      <asp:BoundField datafield="Column5" HeaderText="Column5" />
      <asp:BoundField datafield="Column6" HeaderText="Column6" />
      <asp:BoundField datafield="Column7" HeaderText="Column7" />
      <asp:BoundField datafield="Column8" HeaderText="Column8" />
      <asp:BoundField datafield="Column9" HeaderText="Column9" />
      <asp:BoundField datafield="Column10" HeaderText="Column10" />
      <asp:BoundField datafield="Column11" HeaderText="Column11" />
    </Columns>
  </SharePoint:SPGridView>
  </div>

代码背后：

protected object Items
{
  get
  {
    var dt = new DataTable("Itens");
    dt.Columns.Add("Column0");
    dt.Columns.Add("Column1");
    dt.Columns.Add("Column2");
    dt.Columns.Add("Column3");
    dt.Columns.Add("Column4");
    dt.Columns.Add("Column5");
    dt.Columns.Add("Column6");
    dt.Columns.Add("Column7");
    dt.Columns.Add("Column8");
    dt.Columns.Add("Column9");
    dt.Columns.Add("Column10");
    dt.Columns.Add("Column11");

    for (var i = 0; i < 30; i++)
      dt.Rows.Add("lorem ipsum dolor" + i,"sit amet" + i,"consequetur" + i,"elit" + i,"lorem ipsum dolor" + i,"consequetur" + i);

    return dt;

  }
}

protected void Page_Load(object sender,EventArgs e)
{
  DataBind();
}

ps.：别忘了使用<％= tbl.ClientID％>在javascript中获取实际ID
