如何检查datagridview的行是否大于C＃win表单中的特定数字 [英] How can I check if the rows the rows of a datagridview is greater than a particular number in C# win form

问题描述

大家好，我有一个datagridview，我存储名称，日期和时间，我有一个按钮，如果datagridview中的行大于1
$我不希望它可见b $ b但是按钮不能正常工作



我尝试过：

Good day everyone please i have a datagridview where i store name,date and time, and i have a button that i don't want it to be visible if the row in the datagridview is greater than 1
but the button does not work properly

What I have tried:

if (exam.dataGridView1.Rows.OfType<DataGridViewRow>().Take(1).Count() > 1)
            {
                inexaminfo.Enabled = false;
            }

还有这个

and also this

if (exam.dataGridView1.Rows.Count >1)
            {
                inexaminfo.Enabled = false;
              
            }

推荐答案

使用可见 [ ^ ]属性显示/隐藏控件

use Visible[^] property to show/hide the control

if (dataGridView1.Rows.Count > 1)
     inexaminfo.Visible = false;
