推荐答案

您可以尝试呼吁的onmouseover 事件的JavaScript函数。 <一href=\"http://www.c-sharpcorner.com/uploadfile/mahakgupta/how-to-change-color-of-rows-in-gridview-on-mouseover/\"相对=nofollow>这个网站有一个简单的例子：

You could try calling a javascript function on the onmouseover event. This website has a quick example:

在服务器端：

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes["onmouseover"] =
            "javascript:mouseovercolor(this);";
        e.Row.Attributes["onmouseout"] =
            "javascript:mouseoutcolor(this);";
    }
}

在客户端：

<script language=javascript type="text/javascript">
    function mouseovercolor(mytxt) {
        mytxt.bgColor = 'Orange';
    }
    function mouseoutcolor(mytxt) {
        element.bgColor = 'White';
    }
</script>

编辑：的这个网站有一个很好的例子就如何使之与的onClick 事件工作的：

Edited: This site has a nice example on how to make it work with the onClick event:

服务器端：

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e){
  if (e.Row.RowType == DataControlRowType.DataRow){
    // javascript function to call on row-click event
    e.Row.Attributes.Add("onClick", "javascript:void SelectRow(this);");
  }
 }

客户端：

<script type="text/javascript">
         // format current row
         function SelectRow(row) {
             var _selectColor = "#303030";
             var _normalColor = "#909090";
             var _selectFontSize = "3em";
             var _normalFontSize = "2em";
             // get all data rows - siblings to current
             var _rows = row.parentNode.childNodes;
             // deselect all data rows
             try {
                 for (i = 0; i < _rows.length; i++) {
                     var _firstCell = _rows[i].getElementsByTagName("td")[0];
                     _firstCell.style.color = _normalColor;
                     _firstCell.style.fontSize = _normalFontSize;
                     _firstCell.style.fontWeight = "normal";
                 }
             }
             catch (e) { }
             // select current row (formatting applied to first cell)
             var _selectedRowFirstCell = row.getElementsByTagName("td")[0];
             _selectedRowFirstCell.style.color = _selectColor;
             _selectedRowFirstCell.style.fontSize = _selectFontSize;
             _selectedRowFirstCell.style.fontWeight = "bold";
         }
</script>
