如何知道 datagridview 中的特定复选框是否被选中? [英] How to know a specific checkbox inside datagridview is checked or not?

问题描述

我有一个 gridview，它有 2 列，一个是文本框列，另一个是复选框列，如何知道哪个复选框被选中.

i had a gridview which has 2 columns , one is textbox column and other is checkbox column, how to know which checkbox is checked .

如图所示，假设任何复选框被选中，我想显示该复选框对应的文本框值.

As shown in image ,suppose any of the checkbox is checked , i want to display that the corresponding text box value to that checkbox.

有人可以帮我吗?我尝试了下面的代码，但我面临的问题是，一旦我点击下一个复选框，这些值就会显示出来，然后显示之前选中的复选框值..

can anyone help me?i tried the below code , but problem which i am facing is that , the values is getting displayed once i clicked to next checkbox then the previously checked checkbox values is getting displayed..

dataGridView1.CellValueChanged += new DataGridViewCellEventHandler(dataGridView1_CellValueChanged);

  void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {  
        object tempObj = dataGridView1.Rows[e.RowIndex].Cells[1].Value;
         dataGridView1_CurrentCellDirtyStateChanged(sender, e);

        if (((e.ColumnIndex) == 1) && ((bool)dataGridView1.Rows[e.RowIndex].Cells[1].Value))
        {
            MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString());

        }
    }

推荐答案

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

    private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
        if (((e.ColumnIndex) == 1) && ((bool)dataGridView1.Rows[e.RowIndex].Cells[1].Value))
        {
            MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString());

        }
    }
