I am not sure I understand  your question. Could you, please, clarify? The GridHyperlinkColumn renders links (<a href=""> elements) that redirect to the specified location. If you need to prevent redirection on click, you can find the hyperlink control from the server and set client-side click handler that will return false:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = (GridDataitem)e.Item;
        ((HyperLink)dataItem["AssetName"].Controls[0]).Attributes["onclick"] = "return false";
    }
}

If this is not what you need, can you, please give us further info on your particular scenario.
