如何使用命令参数 Asp.Net WebForms C# 将值传递给 Click 事件
How to pass value to Click event using command argument Asp.Net WebForms C#
我对 ASP.Net
WebForms
知之甚少。现在我面临一个小问题。这里我使用 foreach
迭代列表,同时迭代我想绑定值 linkbutton 命令参数。但是 OnCommand
事件我没有得到价值。
我的代码:
.aspx
<%foreach (var item in model.ItemsWithoutDiscount) {%>
<asp:Button ID="Button1" runat="server" Text="Delete" CommandArgument='<%= item.ID %>' OnCommand="Button1_Click" />
<%}%>
这是我在 .aspx.cs
上的活动
protected void Button1_Click(Object sender, CommandEventArgs e)
{
string ID = e.CommandArgument.ToString();
}
我想将命令参数中的值传递给我的事件。请帮忙
**ASPX**
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
<ItemTemplate>
<asp:Button runat="server" CommandArgument='<%# Eval("ID") %>' Text="Delete" />
</ItemTemplate>
</asp:Repeater>
**C#**
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Repeater1.DataSource=YOUR_DATA_SOURCE;//ItemsWithoutDiscount
Repeater1.DataBind();
// ...
}
}
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandArgument == null)
return;
var id = int.Parse(e.CommandArgument.ToString());
// your logic here ...
}
