数据列表项命令功能不起作用

Question

我试图创建一个带有itemcommand函数的数据列表，尽管由于某种原因，程序似乎没有进入itemcommand的函数。

aspx

<asp:DataList ID="DataList1" runat="server" OnItemCommand="DataList1_ItemCommand" DataKeyField="jobID">
<ItemTemplate>
<div class="jobContainer">
<div class="jobDetails">
<span class="jobName"><%# Eval("jobName") %></span><br /> 
<hr class="style13">
<a class="Details">    <b>Requirments: </b><span ><%# Eval("jobRequirments") %> WPM</span>   </a> 
<a class="Details">  <b>Salary: </b><span ><%# Eval("jobSalary")%> Shekel per hour</span>  </a>

<a class="Details">   <b>City: </b><span ><%# Eval("jobCity")%></span> 
<asp:Button ID="Button1" runat="server" CommandName="Details" Text="Show Details" />

</div>
</div>
</ItemTemplate>
</asp:DataList>

代码隐藏：

protected void Page_Load(object sender, EventArgs e)
{
// getjobs returns a dataset
Service.Service a = new Service.Service();
DataList1.DataSource = a.getjobs();
DataList1.DataBind();
}
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "Details")
{
Response.Redirect("Home.aspx");
}
}

我怀疑您的Page.IsPostBack有问题，因此请确保当页面不是Page_Load中的PostBack时绑定DataList，如下所示：

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) 
{
//Bind your DataList
Service.Service a = new Service.Service();
DataList1.DataSource = a.getjobs();
DataList1.DataBind();
}
}
