问题描述

我必须执行，按钮点击event.checkbox上的复选框检查事件在repeater.i将执行以下代码，但它给出错误。（对象引用未设置对象的实例）



我尝试过：

What I have tried:

        foreach (RepeaterItem item in rptr.Items)
        {
            if (((CheckBox)item.FindControl("Checkbox1")).Checked)
            {
                
            }
        }
    }

推荐答案

没有人看到并运行你的整个代码，没有人可以回答这个问题，使用调试器并检查va线上变量的lue无法看到哪些是null然后解决原因。

No one can answer this question without seeing and running your whole code, use the debugger and check the value of the variables on the line that fails to see which of them is null then solve the reason why.
