如何檢查複選框時選擇數據錶行？

Question

我有一個數據表與每行中的複選框。我想要檢查複選框的行的每個列值。請告訴我如何實現這一點。 這是我的代碼。當複選框被選中時，我想要特定的行細節。

     } 


    } 
    } 

我沒有使用datagrid。我使用網格內的按鈕和複選框顯示我的數據表內容。

Answer 1

You Can use below event of the datagridView 

    private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e) 
     { 
      if (dataGridView1.IsCurrentCellDirty) 
      { 
       dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit); 
      } 
     } 

在我的例子複選框在GridView的色譜柱1並且當其在列2檢查該值可以我不使用數據網格被帶到可變COL

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e) 
     { 
      if (dataGridView1.Columns[e.ColumnIndex].Name == "Column1") 
      { 

       DataGridViewCheckBoxCell checkCell = 
        (DataGridViewCheckBoxCell)dataGridView1. 
        Rows[e.RowIndex].Cells["Column1"]; 
       if ((bool)checkCell.Value == true) { 
        int i = dataGridView1.CurrentRow.Index; 
        string col = dataGridView1.Rows[e.RowIndex].Cells["column2"].Value.ToString(); 
       } 

      } 
     }
