c#中datagridview里checkbox的使用方法

1、属性设置checkboxcolumn   
  
name:cb_check        
falsevalue:false       
truevalue:true  
datagridview中的readonly设置为false.   
  
2、  //单项选择设置   
private void dgv_zy_CellContentClick(object sender, DataGridViewCellEventArgs e)   
        {   
            int count = Convert.ToInt16(dgv_zy.Rows.Count.ToString());   
                    for (int i = 0; i < count; i++)   
{    
{   
DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)dgv_zy.Rows[i].Cells["cb_check"];   {    
                Boolean flag = Convert.ToBoolean(checkCell.Value);   
                if (flag == true)     //查找被选择的数据行   
                {   
                    checkCell.Value = false;   
                }   
                    continue;   
             }   
        }   
  
    
  
3、获取选择的数据   
            int count = Convert.ToInt32(dgv_zy.Rows.Count.ToString());   
            for (int i = 0; i < count; i++)   
            {   
               //如果DataGridView是可编辑的，将数据提交，否则处于编辑状态的行无法取到   
                      dgv_zy.EndEdit();   
                DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)dgv_zy.Rows[i].Cells["cb_check"];   
                Boolean flag = Convert.ToBoolean(checkCell.Value);   
               if (flag == true)     //查找被选择的数据行   
                {   
                    //从 DATAGRIDVIEW 中获取数据项   
               string z_zcode = dgv_zy.Rows[i].Cells[0].Value.ToString().Trim();   
              //........................................                }   
         }

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

{

 

 

You can use any of these statements to get value in the selected cell

textBox1.Text = (string)dataGridView1[e.ColumnIndex, e.RowIndex].Value;

textBox1.Text = (string)dataGridView1.CurrentCell.Value;

textBox1.Text = (string)dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;

If you want only Id value when you selecet any column in a particular row, you can use, change the values in red font as per your requirement that is column(Id column) you are looking for

 

textBox1.Text = (string)dataGridView1[columnIndex or columnName, e.RowIndex].Value;

 

textBox1.Text = (string)dataGridView1.Rows[e.RowIndex].Cells[coulmnIndex or columnName].Value;

 

}
