这次我从头问，希望给个明白的答案，感谢！（datalist嵌套）
<asp:datalist id= "dlDQue " runat= "server ">
<ItemTemplate>
<table>
//这个table里的是问题并且有个btuuton id= "btnShow " CommandName= "Show "
</table>
<div id= "dv " runat= "server ">
<asp:DataList ID= "dlAnswer " Runat= "server " DataSource= ' <%# GetAnswersById(DataBinder.Eval(Container, "DataItem.DQueId ").ToString())%> ' OnItemCommand= "dlAnswer_ItemCommand ">
</datalist> //这个datalist里是单个问题的所有回答
<table>
//这个table里放的是提交回答的信息和提交按钮
</table>
</div>
</ItemTemplate>
<datalist>
我的问题：如何做到点btnshow按钮，来显示知隐藏div
[解决办法]
void Item_Command(Object sender, DataListCommandEventArgs e)
{
if (e.CommandName == "Show ")
{
HtmlGenericControl ctl = e.Item.FindControl( "dv ") as HtmlGenericControl;
ctl.Visible = true;
}
}
[解决办法]
在dlAnswer_ItemCommand这个事件里怎么能取到第二个table里的控件
--------------------------
使用dlAnswer.Parent.FindControl方法试试。
[解决办法]
<asp:datalist id= "dlDQue " runat= "server ">
<ItemTemplate>
<table>
//这个table里的是问题并且有个btuuton id= "btnShow " CommandName= "Show " onclick= "javascript:dv <%# Eval( "dlDQue_id ") %> .style.display= 'none '; "
</table>
<div id= "dv <%# Eval( "dlDQue_id ") %> ">
<asp:DataList ID= "dlAnswer " Runat= "server " DataSource= ' <%# GetAnswersById(DataBinder.Eval(Container, "DataItem.DQueId ").ToString())%> ' OnItemCommand= "dlAnswer_ItemCommand ">
</datalist> //这个datalist里是单个问题的所有回答
<table>
//这个table里放的是提交回答的信息和提交按钮
</table>
</div>
</ItemTemplate>
<datalist>
当然,你直接给runat=server的button加上onclick= "javascript:dv <%# Eval( "dlDQue_id ") %> .style.display= 'none '; " ,会出错的.你可以通过数据绑定,在cs代码中,给每一行的该按钮加上这么一个onclick事件
<input type=button onclick= "javascript:div2.style.display= 'none '; " value= "测试 " />
<div id= "div2 ">
abcabcabcabcabcabcabcabcabcabcabc
</div>
[解决办法]
只要你的table中的控件都是服务器端控件 根据ID值就能找到 如找Button bt1
则在itemDataBind事件中写：
Button bt= e.Item.FindControl( "tb1 ");
找到的是那一行的button实例
[解决办法]
似乎另一帖偶已回答了嘛
[解决办法]
<script type= "text/javascript ">
function showsub(sid)
{
whichEl = eval( "alsub " + sid);
if (whichEl.style.display == "none ")
{
eval( "alsub " + sid + ".style.display=\ "\ "; ");
}
else
{
eval( "alsub " + sid + ".style.display=\ "none\ "; ");
}
}
function shows(sid)
{
whichEl = eval( "al " + sid);
if (whichEl.style.display == "none ")
{
eval( "al " + sid + ".style.display=\ "\ "; ");
}
else
{
eval( "al " + sid + ".style.display=\ "none\ "; ");
}
}
</script>
<asp:GridView ID= "grvCommentList " ShowHeader= "False " PageSize= "4 " runat= "server " AutoGenerateColumns= "False " Width= "700px " AllowPaging= "True " DataSourceID= "objComment ">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<div class= "graytitle " onclick= "shows( <%# Eval( "ID ") %> ) "> <%# Eval( "FullUserName ")%>
<%# Eval( "CommentDate ") %>
</div>
<div id= "al <%# Eval( "ID ") %> "> <br /> <%# Eval( "CommentContent ") %> </div>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<RowStyle HorizontalAlign= "Left " />
