在asp.net中找不到图像控件 [英] image control not found in asp.net

问题描述

我想访问图像按钮..但是以下行不会返回任何内容..这是正确与否？

ImageControlList（）是按钮控件的集合



Dim fileDownloadimgBtn As ImageButton = CType（Page.Form.FindControl（ImageControlList（i）。 ID），ImageButton）

I want to access the image button.. but following line doesnt return anything.. This is correct or not???
ImageControlList() is collection of button control

Dim fileDownloadimgBtn As ImageButton = CType(Page.Form.FindControl(ImageControlList(i).ID), ImageButton)

推荐答案

ImageButton是您表单的子项，还是包含在另一个控件中？如果它是另一个控件的子项，那么您将无法使用该调用直接获取它。您需要从父控件而不是表单执行FindControl。

Is the ImageButton a child of your form, or is it contained in another control? If it is a child of another control then you will not be able to get it directly using that call. You will need to do FindControl from the parent control rather than the form.
