.net的master page下的内容页内如何引用服务端控件实现回调 高手请进!在线等
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"><script language="javascript" type="text/javascript" >
function OpenModalDialog(url, name)
{
var vReturnValue;
if(url != null)
{
vReturnValue = window.showModalDialog(url, "#1", "dialogHeight: 400px; dialogWidth: 600px; dialogTop: 100px; dialogLeft: 100px; edge: Raised; center: Yes; help: No; resizable: No; status: No;");
}
else
{
alert("No URL passed to open");
}
if(vReturnValue != null && vReturnValue == true)
{
__doPostBack(' <%=Image3.UniqueID%>', "");
}
else
{
return false;
}
}
</script>
...
<asp:LinkButton ID="Image3" runat="server" OnClick="Image3_Click"> </asp:LinkButton>
</asp:Content>
注用__doPostBack(' <%=Image3.ClietID%>', ""); 并不能实现回调
__doPostBack(' <%=Image3.UniqueID%>', "");能实现回调,
可执行回调后(比如DATAGRID的重新绑定),DATAGRID却不刷新....
protected void Image3_Click(object sender, EventArgs e)
{
grdWorkProc.DataSource = workproc.GetJuniorWorkProList(Session["SelectedNode"] as string);
grdWorkProc.DataBind();
}
为什么执行了DATAGRID却不刷新,.net的master page下的内容页内如何引用服务端控件实现回调 ?在线等......急!
--------------------编程问答-------------------- 既然都已经Image3_Click事件了，那就不是回调的问题了。在workproc.GetJuniorWorkProList上找原因。 --------------------编程问答-------------------- 晕,楼上的,这个问题就不要怀疑了,这个肯定是没问题的
因为如果我点击image3的话,同样触发该事件是可以刷新数据的 --------------------编程问答-------------------- 你怎么知道能够回调? --------------------编程问答-------------------- 设断点..已经执行了呀..晕..
至少2003的时候这样是肯定能刷新数据的,项目中经常用
可是05不知道为什么就不行了:(,难道不支持了?还是需要什么配置!
请高手指教..这个问题已经困扰一段时间了,可没人能回答..这是真实存在的问题呀
其实最终的问题是语句执行了,可是DATAGRID却不刷新,而如果你直接点击的话,却是可以刷新的
所以应该是回调时还要注意什么问题,请高手指教,真是没办法,着急 --------------------编程问答--------------------
你先把母版页里有哪些东东,还有子页面有什么东东,说清楚,分析分析.
事件是发生在哪的? --------------------编程问答-------------------- lz不说清楚,怎么解决啊? --------------------编程问答-------------------- 母版页HTML:(其实暂时什么也没有)

ClientScript.RegisterStartupScript(Page.GetType(), "PopupScript", script);
}
}
最终的结果是执行了
protected void Image3_Click(object sender, EventArgs e)
{
this.GridView1.DataBind();
}
但是却不刷新数据表
--------------------编程问答-------------------- 刚才下班了,回来写了个测试程序..大家看下,不访试试,问题怎么解决? --------------------编程问答-------------------- [img=http://photo.store.qq.com/http_imgload.cgi?/rurl2=b0ee1fb650b234eaa917b8fb6ad1ee87308eb35ae4455efbd5dcb54c43aaf2f2d42b4de4ac0c36f5029c9e4cda400147177ac75dc15cfed5a267209d181af82deaea00d543596da65698ec40ce844a7b5c34da02][/img]
点击ADD,弹出对话框AddDept.aspx,输入值10,10,10,点击OK返回到TestRefresh.aspx,最终执行了
protected void Image3_Click(object sender, EventArgs e)
{
this.GridView1.DataBind();
}
却gridView1却并没有刷新,可是你点击IMAGE3就可以刷新(可以设置下IMAGE3.TEXT)
补充：.NET技术 , ASP.NET
