У меня есть 10 вопросов в моей базе данных sql. Я получаю их и печатаю их в форме "Ссылка" с помощью LinkButton. Теперь я хочу генерировать событие click для каждого вопроса отдельно.

Как создать событие OnClick LinkButton внутри ListView. Пожалуйста, помогите в простых шагах.

  <asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="userid" >
<AlternatingItemTemplate>
<tr style="">
<td>
<%-- <asp:Label ID="qtLabel" runat="server" Text='<%# Eval("qt") %>' />
--%>
<h3> <asp:LinkButton CommandArgument='<%# Eval("userid") %>' ID="LinkButton1" runat="server"><%# Eval("qt") %></asp:LinkButton> </h3>

</td>
<td>
<asp:Label ID="useridLabel" runat="server" Text='<%# Eval("userid") %>' />
</td>
</tr>
</AlternatingItemTemplate>
<EditItemTemplate>
<tr style="">
<td>
<asp:Button ID="UpdateButton" runat="server" CommandName="Update" Text="Update" />
<asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Cancel" />
</td>
<td>
<asp:TextBox ID="qtTextBox" runat="server" Text='<%# Bind("qt") %>' />
</td>
<td>
<asp:Label ID="useridLabel1" runat="server" Text='<%# Eval("userid") %>' />
</td>
</tr>
</EditItemTemplate>
<EmptyDataTemplate>
