dev gridControl gridView循环删除问题

 foreach (DataGridViewRow row1 in dataGridView1.Rows)
                        {
                            if ((row1.Tag as LayerTableRecord) == ltr)

                                dataGridView1.Rows.Remove(row1);
                                break;
                            }
                        }
//dev
foreach (GridView row in 此处需填什么？)
                {
                    if ((row.Tag as LayerTableRecord) == ltr)
                    {
                        //gridView1的删除怎么操作的。
                        break;
                    }
                }

怎么dataGridView1系统的表格，来循环删除？不会了请大师。

可以使用迭代得方式删除

```java
private void gridControl1_ProcessGridKey(object sender, KeyEventArgs e)
        {
            DevExpress.XtraGrid.Views.Base.ColumnView view = (sender as DevExpress.XtraGrid.GridControl).FocusedView as DevExpress.XtraGrid.Views.Base.ColumnView;
            if (view == null) return;
            if (e.KeyCode == Keys.Delete && e.Control && view.OptionsBehavior.AllowDeleteRows!= DevExpress.Utils.DefaultBoolean.False && view.SelectedRowsCount > 0)
            {
                if (DevExpress.XtraEditors.XtraMessageBox.Show($"确定删除所选{view.SelectedRowsCount}行？", "提问", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
                    view.DeleteSelectedRows();
            }
 
        }

```

• 你看下这篇博客吧, 应该有用👉 ：Dev中GridControl设置指定列表头的背景色

类似于这样，选中后，后端进行删除操作
int[] rows = gridView1.GetSelectedRows();

if (rows.Length > 0)
{
if (DialogHelper.YesNo(this, "确认删除该记录?", "删除提示") != System.Windows.Forms.DialogResult.Yes) return;

DataRowView drv = (DataRowView)gridView1.GetRow(rows[0]);

//_layerUpdater.b.Rows.Remove(drv.Row);
drv.Row.Delete();
}

参考一下

for (int i = dataGridView1.Columns.Count-1 ; i >=0; i--)

{

    if (dataGridView1[i, 0].Value.ToString() == "0.0000000000")

    {

        dataGridView1.Columns.Remove(dataGridView1.Columns[i]);

    }

}
