尝试编辑包含maskedtextbox的单元格时遇到问题:
如果我尝试编辑字段,我需要:
((4。开始输入值)
有可能以某种方式避免“手动”聚焦到maskedtextbox的第一个位置? (例如,在单击或双击时:将maskedtextbox设置为可见,同时将焦点/光标设置在maskedtextbox的第一个位置上)
我尝试过:focus(),select(),SelectionStart,CurrentCell,但是没有运气。
我通过以下方式向DataGridView单元添加了MaskedTextbox:
public Insert()
{
InitializeComponent();
this.maskedTextBox = new MaskedTextBox();
this.maskedTextBox.Visible = false;
this.dataGridView1.Controls.Add(this.maskedTextBox);
this.dataGridView1.CellBeginEdit += new DataGridViewCellCancelEventHandler(dataGridView1_CellBeginEdit);
this.dataGridView1.CellEndEdit += new DataGridViewCellEventHandler(dataGridView1_CellEndEdit);
this.dataGridView1.Scroll += new ScrollEventHandler(dataGridView1_Scroll);
}
void dataGridView1_Scroll(object sender, ScrollEventArgs e)
{
if (this.maskedTextBox.Visible)
{
Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(
this.dataGridView1.CurrentCell.ColumnIndex,
this.dataGridView1.CurrentCell.RowIndex, true);
this.maskedTextBox.Location = rect.Location;
}
}
void dataGridView1_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)
{
if (e.ColumnIndex == this.dataGridView1.Columns[4].Index || e.ColumnIndex == this.dataGridView1.Columns[5].Index && e.RowIndex > -1)
{
string type = "";
if (this.dataGridView1[e.ColumnIndex, e.RowIndex].Value != null)
type = this.dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
this.maskedTextBox.Mask = "0000.00.00";
Rectangle rect =
this.dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
this.maskedTextBox.Location = rect.Location;
this.maskedTextBox.Size = rect.Size;
this.maskedTextBox.Text = "";
if (this.dataGridView1[e.ColumnIndex, e.RowIndex].Value != null)
{
this.maskedTextBox.Text = this.dataGridView1[e.ColumnIndex,
e.RowIndex].Value.ToString();
}
this.maskedTextBox.Visible = true;
this.maskedTextBox.Focus(); //tried
this.maskedTextBox.Select(0, 0);
this.maskedTextBox.SelectionStart =0 ;
dataGridView1.CurrentCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
}
}
void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
if (this.maskedTextBox.Visible && (e.ColumnIndex == this.dataGridView1.Columns["TEST"].Index && e.RowIndex > -1))
{
this.dataGridView1.CurrentCell.Value = maskedTextBox.Text;
this.maskedTextBox.Visible = false;
}
}
控件可能需要获取焦点之后
