提问by Hunter Mitchell
I am currently using this code:
我目前正在使用此代码：
foreach (DataGridViewRow item in this.dataGridView1.SelectedRows)
{
dataGridView1.Rows.RemoveAt(item.Index);
}
I have checkmarks down the first column, but with this code, it only get the selected. How do i get the Selected CheckBoxes onlyto delete with the row?
我在第一列下有复选标记，但使用此代码，它只能选中。如何让 Selected CheckBoxes只与行一起删除？

Try something like this:
尝试这样的事情：
foreach(DataGridViewRow row in this.dataGridView1.Rows)
{
var checked = Convert.ToBoolean(row.Cells[0].Value); // Assuming the first column contains the Checkbox
if(checked)
dataGridView1.Rows.RemoveAt(row.Index);
}

It could be something like this... This is an example for listview, however the concept is almost there. Loop through the item and find the checkbox id and remove those selected. Hope this helps.
它可能是这样的......这是一个列表视图的例子，但是这个概念几乎就在那里。循环遍历该项目并找到复选框 ID 并删除选中的那些。希望这可以帮助。
public void btnDeleteClick(object sender, EventArgs e)
{
// Iterate through the ListViewItem
foreach (ListViewItem row in ListView1.Items)
{
// Access the CheckBox
CheckBox cb = (CheckBox)row.FindControl("cbxID");
if (cb != null && cb.Checked)
{
// ListView1.DataKeys[item.DisplayIndex].Values[0].ToString()
try
{
}
catch (Exception err)
{
}
}
}
}

Try this:
尝试这个：
if (dgv.SelectedRows.Count>0)
{
dgv.Rows.RemoveAt(dgv.CurrentRow.Index);
}
