Datagridview 添加checkbox列，并判断Datagridview 中的checkbox列是否被选中

Solution1:
//In Fill DataGridViewEvent :

DataGridViewCheckBoxColumn ChCol = new DataGridViewCheckBoxColumn();

ChCol.Name = "CheckBoxRow";

ChCol.HeaderText = "CheckboxSelection";

ChCol.Width = ;

ChCol.TrueValue = "";

ChCol.FalseValue = "";

datagridview_tabpage1.Columns.Insert(, ChCol);

// In Button Event put these codes:

datagridview 中的checkbox列是否被选中

private void button3_Click(object sender, EventArgs e)

{

string selectRows="";

for (int i = ; i < dataGridView_tabPage1.Rows.Count - ; i++) //循环datagridview每行

{

if ((bool)dataGridView_tabPage1.Rows[i].Cells[].EditedFormattedValue == true)

{

selectRows = selectRows + "[" + i.ToString() + "]";

}

}

MessageBox.Show("Selected Rows:" + selectRows,"CheckBoxRows");

}


add check box in Datagridview

   // Initialize and add a check box column.

            DataGridViewColumn column = new DataGridViewTextBoxColumn();

            column = new DataGridViewCheckBoxColumn();

            column.DataPropertyName = "selection";

            column.Name = "selection";

            dataGridView_tabPage1.Columns.Add(column);

全选

  //循环dataGridView

   for (int i = ; i < dataGridView_tabPage1.Rows.Count; i++)

   {

       //设置设置每一行的选择框为选中，第一列为checkbox

      dataGridView_tabPage1.Rows[i].Cells[].Value = true;

   }

反选

//循环dataGridView

for (int i = ; i <dataGridView_tabPage1.Rows.Count; i++)

{

//判断当前行是否被选中

  if ((bool)dataGridView_tabPage1.Rows[i].Cells[].EditedFormattedValue == true)

      //设置每一行的选择框为未选中

    dataGridView_tabPage1.Rows[i].Cells[].Value = false;

  else

     //设置每一行的选择框为选中

     dataGridView_tabPage1.Rows[i].Cells[].Value = true;

 }
