如何输入动态生成的文本框的文本框文本 [英] how can i get entered textboxes text of dynamically generated textboxes

问题描述

我创建了动态文本框。我有该文本框的ID ...我想将文本框中输入的文本插入数据库..如何做到这一点???

解决方案

所有控件值存在于Request对象中。您可以使用控件名称（UniqueID）而不是id从Request对象获取值。语法如下：

  var  textBoxValue = Request [txtBox.UniqueID ]; 

如果这没有用，请告诉我。

这取决于哪里你正在创建控件。我知道的简单解决方案：在内创建控件Page_PreInit 事件。



Page_PreInit 事件将轻松渲染您的控件并存储控件的 ViewState 。

然后你可以使用以下代码轻松找到动态创建的控件：

 TextBox TextBox1 =（TextBox）Page.FindControl（  TextBox）;

I have created dynamic textboxes. i have got id of that textbox...i want to insert text which entered in textbox into database..how to do that???

解决方案

All the control values are present in Request object. You can fetch value from Request object using control name (UniqueID) not id. Syntax is given below

var textBoxValue = Request[txtBox.UniqueID];

Please let me know if this does not help.

It depends on where you are creating the controls. Simple solution which I ever know : Create controls inside Page_PreInit Event.

Page_PreInit event will render your controls easily and store the ViewState of your controls.
Then you can easily find the controls created dynamically using the following code:

TextBox TextBox1= (TextBox)Page.FindControl("TextBox");

If you need little more help or guideline while creating the controls then refer the links for similar articles:
