Change your function to this:
将您的功能更改为：
protected void BindDataToGridviewDropdownlist()
{
XmlTextReader xmlreader = new XmlTextReader(Server.MapPath("xml/XMLFILE.xml"));
DataSet ds = new DataSet();
ds.ReadXml(xmlreader);
xmlreader.Close();
if (ds.Tables.Count != 0)
{
foreach (DataRow dr in ds.Tables[0].Rows)
{
ListItem li = new ListItem(dr["name"].ToString(), dr["name"].ToString());
li.Attributes.Add("data-image", "images/" + dr["img"].ToString());
ddlDetails.Items.Add(li);
}
}
}
This will add an extra attribute to the options inside your selectBox, needed by the plugin.
这将为插件所需的 selectBox 中的选项添加一个额外的属性。
