如何检查FormView是否为空

How can I check if a Form View is empty from code behind? I've tried DataItemCount ==0 but it doesn't seem to work. Thanks

如何检查表单视图是否为空?我试过DataItemCount =0，但是好像不太好用。谢谢

if (FormView_imgBG.DataItemCount == 0)

            { //do stuff
            }
            else 

            {                 
            // do other stuff
            }

People are saying that the best place to check the DataItemCount property is in the FormView.DataBound event.

人们说检查DataItemCount属性的最佳位置是在FormView中。数据绑定事件。

    protected void FormView1_DataBound(object sender, EventArgs e) {
        if (FormView1.DataItemCount == 0) {
        }
        else {
        }
    }
