嗨Ralf Meier，
道歉，因为我没有添加c＃.net标签，因为我很难添加c＃.net标签。
我想要选中复选框状态toolstripbutton点击事件但是我选择了复选框，它总是返回false。
但是如果我使用普通按钮它正常工作。
以上代码示例将突出显示我的问题。
< pre lang =c＃> private void toolStripButton2_Click（ object sender，EventArgs e）
{
List< datagridviewrow> rows_with_checked_column = new List< datagridviewrow>（）;
foreach （DataGridViewRow row in dataGridView1.Rows）
{
if （Convert.ToBoolean（row.Cells [ chk]。值）== true ）
{
// rows_with_checked_column.Add（row）;
MessageBox.Show（ 选中）;
}
else
{
MessageBox.Show（ 未选中）;
}
}
}
< / datagridviewrow > < / datagridviewrow < span class =code-keyword>>

Hi Ralf Meier,
Apologies, for not adding c#.net tag , as i had difficulty in adding c#.net tag.
I want to get the checkbox selected status in the toolstripbutton click event but eventhough i selected the checkbox its always returns false .
But if i use normal button its working properly .
The Above code sample will highlight my issue.
private void toolStripButton2_Click(object sender, EventArgs e) { List<datagridviewrow> rows_with_checked_column = new List<datagridviewrow>(); foreach (DataGridViewRow row in dataGridView1.Rows) { if (Convert.ToBoolean(row.Cells["chk"].Value) == true) { //rows_with_checked_column.Add(row); MessageBox.Show("Checked"); } else { MessageBox.Show("not Checked"); } } } </datagridviewrow></datagridviewrow>
这篇关于ToolStripButton单击事件无法复选框选中状态对于WindowsForm中的DataGridView的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
