在隐藏特定列之前想要检查那个列值是否有你要清除 [英] Before hiding the specific column want to check in that column values are there u wan to clear

问题描述

隐藏按钮代码如下;

Hide button code as follows;

private void Btn_Hide_Click(object sender, EventArgs e)
       {
 if (MessageBox.Show("Are You sure, You want to Hide?", "Hide confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
           {
               datagridView.Columns[datagridView.CurrentCellAddress.X].Visible = false;
           }

       }

来自上面的代码，当我点击隐藏按钮消息弹出窗口你确定，你想要隐藏吗？



但是在此消息显示之前，

该列的课程是如果用户说是清除项目并隐藏特定列，你想要清除。



输出如下;

隐藏（按钮） ）



日期会议RK Mk GS VB



2013年1月7日1 tam（课程）

2/7/2013 2



当我点击隐藏按钮验证该RK列tam值是否存在时。



如果用户说清楚tam课程然后隐藏专栏，你首先要清除tam（课程）。



如何验证清除tam课程

from the above code when i click the hide button the message popups Are You sure, You want to Hide?.

but before this message shows,
for that column the course is there do u want to clear if user says yes clear the item and hide the particular column.

Output as follows;
Hide (Button)

Date Session RK Mk GS VB

1/7/2013 1 tam (course)
2/7/2013 2

when i click the hide button validate for that RK column tam value is there.

first do u want to clear the tam (course) if user says yes clear the tam course and then hide the column.

how to validate to clear the tam course

推荐答案

我不太明白你的问题，但这里是一个代码snipp et，这是你要找的吗？

I dont quite understand your question but here is a code snippet, is this what you were looking for?

private void button1_Click(object sender, EventArgs e)
{
     if (string.IsNullOrEmpty(dataGridView1.CurrentRow.Cells["Column Name"].Value.ToString()))
     {
          if (MessageBox.Show("Are You sure, You want to Hide?", "Hide confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
          {
               dataGridView1.Columns[dataGridView1.CurrentCellAddress.X].Visible = false;
          }
     }
     else
     {
          if (MessageBox.Show("Are You sure you want to clear course?", "Clear Course", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
          {
               dataGridView1.Columns[dataGridView1.CurrentCellAddress.X].Visible = false;
          }
     }
}
