如何在Web用户控件(ASCX)中创建公共方法? [英] How to create a Public Method in a Web User Controll(ASCX)?

问题描述

我创建了一个带有6个Buttons.Which的用户控件，其中包括(NEW，Edit，Delete，SAVE，CLEAR，PRINT).默认情况下，编辑"和删除"按钮为禁用".我需要的是将此用户控件添加到页面时.在网格视图中选择一行时，需要启用该编辑和删除"按钮.有人可以告诉我如何声明一种从Web表单(.CS文件)启用该按钮的方法吗???多谢！！！！我想我将需要一种方法来完成该任务.如果有人可以在此问题上为我提供帮助，那将对我有很大帮助. div>

只需在事件中使btnUpdate.enable = true并将autopostback设置为true.

我建​​议改为在用户控件内设置公共属性

 公共 布尔 ButtonEnabled
{
 设置
 {
  btnSubmit.enabled = 值;
 }
 获取
 {
  返回 btnSubmit.enabled;
 }
} 

这样，您可以从页面中的代码(如

 usercontrol1.ButtonEnabled =  false ; 

甚至从页面的aspx标记为

 <   uc:usercontrol     id   ="    已启用按钮  ="  false"  xmlns:uc   #unknown" / >  

告诉我我的理解是否正确，我将尝试完善解决方案.

Hi , i create a User Control with 6 Buttons.Which includes (NEW ,Edit , Delete , SAVE , CLEAR ,PRINT). by default Edit and DELETE buttons are Disabled.What i need is when i add this user control to a page. need to enable that Edit and Delete button when select a row in the Grid view.can someone tell me how to declare a method to enable that buttons from a web form(.CS file)??? Thanks a Lot!!!! i guess i ''ll need a method for achieving that task.if someone could help me on this matter, that would be a great help for me.Thanks in advance!!!

解决方案

just make btnUpdate.enable = true at the event and turn autopostback to true.

I suggest make public properties instead inside user control

public bool ButtonEnabled
{
 set
 {
  btnSubmit.enabled = value;
 }
 get
 {
  return btnSubmit.enabled;
 }
}

this way you can do it from code in the page like

usercontrol1.ButtonEnabled = false;

and even from the aspx markup of page as

<uc:usercontrol id="usercontrol1" buttonenabled="false" xmlns:uc="#unknown" />

Tell me if my understanding is not correct and i will try to refine the solution.
