我有一個包含多列的DataGridView,第一列類型是Combobox。當CurrentCell發生變化時,DataGridView ComboBox會丟失它的值
我試圖把重點放在下一個(第2)小區時,組合框的選擇被改變(通過點擊鼠標或按一個鍵)
我居然做到了,但問題是話題說什麼:如果我干擾.CurrentCell以便將焦點集中到下一個單元格,單元格內的組合框項會丟失其值。
如果我按<輸入,只保留其值>或<標籤>更改組合框的值
DataGridView1.EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(DataGridView1_EditingControlShowing);
private void DataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
e.CellStyle.BackColor = Color.Red;
e.CellStyle.ForeColor = Color.White;
if (e.Control.GetType() == typeof(DataGridViewComboBoxEditingControl))
{
Console.WriteLine("adding handler");
ComboBox cmb = (ComboBox)e.Control;
//cmb.SelectedIndexChanged -= new EventHandler(ComboBox_SelectedIndexChanged);
//cmb.SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged);
cmb.SelectionChangeCommitted -= new EventHandler(cmb_SelectionChangeCommitted);
cmb.SelectionChangeCommitted += new EventHandler(cmb_SelectionChangeCommitted);
}
}
void cmb_SelectionChangeCommitted(object sender, EventArgs e)
{
ComboBox cmb = (ComboBox)sender;
Console.WriteLine("Index #{0} Value:{1}", cmb.SelectedIndex.ToString(), cmb.SelectedValue.ToString()); //its working
DataGridViewCell c = DataGridView1.CurrentCell; //get current cell
DataGridView1.CurrentCell = DataGridView1[1, c.RowIndex]; //skips to next cell on the same row
//here combobox lost its value after focusing on another cell!
}
