你好那里
任何人都可以帮助我解决这个C#问题。我正在把这件事撕掉。我会提供尽可能多的信息。我无法使DataGridViewCheckBoxColumn事件正常工作。尽管我点击了复选框,它总是会得到一个FALSE值。其他datagridviews(文本和组合框)列工作正常。这是我在做什么......
好的,所以我在运行时动态地在我的构造函数中创建datagridviews(DGVs),它基于标签控件中有多少标签页,这些标签页由任意几星期指定日期范围内即每个标签页面(即每个星期标签页)C#编程创建datagridview - DataGridViewCheckBoxColumn cellValueChanged检查状态总是返回FALSE
for (int i = 0; i < wcNumWeeks; i++)
{
foreach (DataRow dr in wbDatesDT.Rows)
{
if (Convert.ToInt16(dr["tabNo"].ToString()) == i + 1)
{
wcDate = Convert.ToDateTime(dr["wcDate"].ToString());
break;
}
}
weeksTabControl.TabPages.Add(wcDate.ToShortDateString());
weeksTabControl.TabPages[i].AutoScroll = true;
weeksTabControl.TabPages[i].Width = 1500;
weeksTabControl.TabPages[i].Height = 700;
weeksTabControl.TabPages[i].Controls.Add(new DataGridView()
{
Name = "dataGridView" + (i + 1).ToString(),
Dock = DockStyle.Fill,
Width = 1450,
Height = 650,
Anchor = (AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right),
ScrollBars = System.Windows.Forms.ScrollBars.Both,
AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells
});
}
再在构造,每个datagridview的创建,我创建事件,如下一个DGV:
foreach (Control thisControl in weeksTabControl.Controls)
{
if (thisControl.GetType() == typeof(TabPage))
{
foreach (Control dgv in thisControl.Controls)
{
if (dgv.GetType() == typeof(DataGridView))
{
BuildWhiteboardDGV((DataGridView)dgv);
PopulateWhiteboardDGV((DataGridView)dgv);
wbDataGridView = (DataGridView)dgv;
wbDataGridView.CellMouseUp += new DataGridViewCellMouseEventHandler(wbDataGridView_CellMouseUp);
wbDataGridView.CellEndEdit += new DataGridViewCellEventHandler(wbDataGridView_CellEndEdit);
wbDataGridView.CurrentCellDirtyStateChanged += new EventHandler(wbDataGridView_CurrentCellDirtyStateChanged);
wbDataGridView.CellValueChanged += new DataGridViewCellEventHandler(wbDataGridView_CellValueChanged);
}
}
}
}
012是个 事件本身如下:
void wbDataGridView_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
if (wbDataGridView.IsCurrentCellDirty)
{
wbDataGridView.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
}
void wbDataGridView_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
try
{
if (e.ColumnIndex >= 13 && e.ColumnIndex <= 15)
{
System.Drawing.Point cur = new System.Drawing.Point(e.ColumnIndex, e.RowIndex);
DataGridViewCheckBoxCell curCell = (DataGridViewCheckBoxCell)wbDataGridView[cur.X, cur.Y];
if (curCell.Value != null && (bool)(curCell.Value) == true)
{
MessageBox.Show("TRUE");
}
else if (curCell.Value != null && (bool)(curCell.Value) == false)
{
MessageBox.Show("FALSE");
}
else
{
MessageBox.Show("NULL");
}
}
return;
}
catch (Exception ex)
{
MessageBox.Show("wbDataGridView_CellValueChanged() ERROR - " + ex.Message + " --> " + ex.InnerException.ToString());
return;
}
}
谁能告诉我在哪里,我错了,并指出我在正确的方向。
提前感谢

我无法找到任何使它不适用于我的东西。您的方法'wbDataGridView_CurrentCellDirtyStateChanged'和'wbDataGridView_CellValueChanged'为我工作时,我插入一个简单的DataGridView只有一列作为复选框列。我在其他发布的代码中看不到任何其他内容,看起来会以任何方式影响它。 –
