Freezing (Locking) columns in SPGridView

I'have seen many examples with freezing columns in SPGridView, but I have no idea, why none of them doesn't work for me. I mean - there is no frozing.

I will be gratefull for a look at my code.

Below are pieces of code, which are ready to launch. It has to works on IE 8+ (other browsers don't matter).

I'll give a 100 points for solution which will work.

style

/* Locks the left column */

td.locked, th.locked {

font-size: 7pt;

text-align: left;

background-color:inherit;

color:Black;

position:relative;

cursor: default;

left: expression(document.getElementById("div-datagrid").scrollLeft-2); /*IE5+ only*/

}

/* Locks table header */

th {

font-size: 7pt;

font-weight: bold;

text-align: center;

background-color: navy;

color: white;

height:15pt;

border-right: 1px solid silver;

position:relative;

cursor: default;

top: expression(document.getElementById("div-datagrid").scrollTop-2); /*IE5+ only*/

z-index: 10;
}


/*

/*

div#div-datagrid {

/* Locks the left column */

}

/* Keeps the header as the top most item. Important for top left item*/
th.locked {z-index: 99;}

/* DataGrid Item and AlternatingItem Style*/

I output I have

The problem you are facing (based on the example site you linked) is that the "working version" on the web only works in Quirks Mode, but your SharePoint 2010 page won't even open in Quirks Mode if you force that on the Master Page.

If you are able to use jQuery you can easily create a duplicate of the first column (if you want the first column), I'll play around with some code and with edit this later.

EDIT w/ solution: http://jsfiddle.net/q48dS/

EDIT2: On your Visual Web Part:

<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>

Code Behind:

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, "sit amet" + i, "consequetur" + i, "elit" + i, "lorem ipsum dolor" + i, "sit amet" + i, "consequetur" + i);

    return dt;

  }
}

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

ps.: dont forget to use <%= tbl.ClientID %> to grab the actual Id in the javascript

if you can, use RadGrid for ASP.Net AJAX (Telerik). see this link
