我想编辑image标签里面的属性 可以更新了之后还是原来的值 有人能帮忙解答下吗

[叶子]

加个断点调试一下，你的更新的代码执行了吗？

[josephSC]

跟踪调试过吗？是不是向datatable传递过程中丢失的？

[jack15850798154]

楼主，调试一样看看问题出在哪里。看看DATATABLE中有值吗？

[lcglvgn]

那个问题解决了 现在有一个新的问题 当我删除的时候会删除很多行

[code=C#]
GridViewRow row = GridView1.Rows[e.RowIndex];
int curr = row.RowIndex;
DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath(xmlPath));
dr = ds.Tables[1].Rows[row.DataItemIndex];
DataRow dr = ds.Tables[1].Rows[curr];
dr.Delete();
ds.WriteXml(Server.MapPath(xmlPath));
ResetParameter();
[code]

[lcglvgn]

也就是出来本分类的内容被删除了 还有别的分类的内容被删除了 能说明是为什么吗 怎么解决

DataRow 内容是否正确
遍历XML删除节点
XmlNodeList xnl=xmlDoc.SelectSingleNode("").ChildNodes;
foreach(XmlNode xn in xnl)
{
XmlElement xe=(XmlElement)xn;

}
xmlDoc.Save("a.xml");
