你好那裏
任何人都可以幫助我解決這個C#問題。我正在把這件事撕掉。我會提供儘可能多的信息。我無法使DataGridViewCheckBoxColumn事件正常工作。儘管我點擊了複選框,它總是會得到一個FALSE值。其他datagridviews(文本和組合框)列工作正常。這是我在做什麼......
好的,所以我在運行時動態地在我的構造函數中創建datagridviews(DGVs),它基於標籤控件中有多少標籤頁,這些標籤頁由任意幾星期指定日期範圍內即每個標籤頁面(即每個星期標籤頁)C#編程創建datagridview - DataGridViewCheckBoxColumn cellValueChanged檢查狀態總是返回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
});
}
再在構造,每個datagridview的創建,我創建事件,如下一個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是個 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;
}
}
誰能告訴我在哪裏,我錯了,並指出我在正確的方向。
提前感謝

我無法找到任何使它不適用於我的東西。您的方法'wbDataGridView_CurrentCellDirtyStateChanged'和'wbDataGridView_CellValueChanged'爲我工作時,我插入一個簡單的DataGridView只有一列作爲複選框列。我在其他發佈的代碼中看不到任何其他內容,看起來會以任何方式影響它。 –
