Question

asp.net 未将对象引用设置到对象的实例。怎么解决啊

代码如下 protected void pdd1_repeater_DataBinding(object sender, EventArgs e)
{
((TextBox)pdd1_repeater.FindControl("pidName_tb")).Enabled = false;
}

Answer 1

((TextBox)pdd1_repeater.FindControl("pidName_tb")).Enabled = false;
改成
TextBox txt = (TextBox)pdd1_repeater.FindControl("pidName_tb")；
txt.enabled = false;

Answer 2

TextBox txtBI = (TextBox)pdd1_repeater.FindControl("pidName_tb")；
txtBI .enabled = false;

Answer 3

((TextBox)pdd1_repeater.FindControl("pidName_tb")).Enabled
找不到pidName_tb吧，你设置一个断点看看。

Answer 4

你先判断一下你找的控件是否存在
