将动态页面中的文本框更改为文件上传
奇怪的要求.您应该已经说明了尝试执行此操作的原因和原因.
除了solution1以外，如果您要这样做

选项1:
在运行时，您可以找到文本框并将其从控件面板中删除.创建一个新的文件上传控件并将其添加到面板中

选项2:
将文本框和文件上传控件同时保留在页面中的所需位置之前.将一个的可见性设置为true，将另一个设置为false.在运行时，只要需要就可以切换控件的可见性.这也将帮助您简化控件的生命周期.

试试吧！

change textbox in dynamic page to fileupload
Strange requirement. You should have explained the scenario on what and why you are trying to do this.

Apart from solution1, if you want to do it then

Option 1:
at runtime, you can find the textbox and remove it from the controls panel. Create a new fileupload control and add it to the panel

Option 2:
Keep both the textbox and file upload control in your page from before at the location needed. Set the visibility of one as true and other as false. At runtime, whenever needed just toggle the visibility of the controls. This will also help you to keep the life cycle of control simple.

Try!
