DataList的SelectedItemTemplate内的按钮 [英] button inside SelectedItemTemplate of DataList

问题描述

我有一个DataList，并且SelectedItemTemplate里面有一个按钮.
< asp:按钮ID ="getDetails"符文=>服务器文本="发送查询"CommandName =" SendEnquiry字体名称=" verdana字体大小=" 8pt高度=" 20px宽度=" 90px"/>
单击此按钮后，我应该知道该按钮引发了该事件.为此，我编写了以下代码.

I have a DataList and inside the SelectedItemTemplate there is a button.
<asp:Button ID="getDetails" runat ="server" Text ="Send Enquiry" CommandName ="SendEnquiry" Font-Names ="verdana" Font-Size ="8pt" Height ="20px" Width ="90px" />
When this button is clicked I should know wheather the event is raised by this button. For this purpose I had written the following code.

protected void carList_ItemCommand(object sender, DataListCommandEventArgs  e)
   {
       try
       {
           if(e.CommandName =="SendEnquiry")
           {
               Label12.Text = "Send Enquiry";
           }
           else
           {
               Label12.Text ="Do not send";
           }
       }
       catch (Exception e1)
       {
           Label12.Text = e1.Message.ToString();
       }
    }

但是，当我单击此按钮时，上述条件就永远不会成为现实.任何人都可以告诉我什么地方出了问题.

But when I click this button the above condition is never becoming true. Can anyone tell what is wrong.

Thanks in advance!

推荐答案

我想知道的第一件事就是为什么需要在数据列表中保留按钮.
这样做的目的是什么?

first thing i would like to know is why you need to keep button in datalist.
what is your purpose behind doing that

将Asp:Button转换为 Asp:LinkButton.会工作的.

即:

Convert the Asp:Button into an Asp:LinkButton. It will work.

That is:

<asp:LinkButton ID="getDetails" runat="server" Text="Send Enquiry" CommandName="SendEnquiry" Font-Names="verdana" Font-Size="8pt" Height="20px" Width="90px" />

或者，您必须对Asp:Button使用UseSubmitBehavior="false"属性，以使其起作用.即:

Or, you have to use the UseSubmitBehavior="false" property for the Asp:Button, to make it work. That is:

<asp:Button ID="getDetails" runat="server" Text="Send Enquiry" UseSubmitBehavior="false" CommandName="SendEnquiry" Font-Names="verdana" Font-Size="8pt" Height="20px" Width="90px" />

原因是，默认情况下，Asp:Button呈现提交"按钮，如果DataList 具有提交行为，则DataList 不起作用.因此，您需要标记UseSubmitBehavior="false"


祝你好运:)

The reason is, by default an Asp:Button renders an Submit button and DataList doest not work if the button has a Submit behaviour. So, you need to mark the UseSubmitBehavior="false"


Good luck :)
