好坏
我在DataGridView中列托管不同的控件。 当我在同一时间添加控件初始化我网格控件显示为文本框(BAD)。 如果我的控件添加在DataGridView已初始化后控件呈现正常(GOOD)。
public Form1()
{
InitializeComponent();
ControlsInGridViewColumn(); //<- renders controls as textboxes
}
private void button1_Click(object sender, EventArgs e)
{
ControlsInGridViewColumn(); //<- does correctly render controls
}
private void ControlsInGridViewColumn()
{
DataTable dt = new DataTable();
dt.Columns.Add("name");
for (int j = 0; j < 10; j++)
{
dt.Rows.Add("");
}
this.dataGridView1.DataSource = dt;
this.dataGridView1.Columns[0].Width = 200;
DataGridViewComboBoxCell ComboBoxCell = new DataGridViewComboBoxCell();
ComboBoxCell.Items.AddRange(new string[] { "aaa","bbb","ccc" });
this.dataGridView1[0, 0] = ComboBoxCell;
this.dataGridView1[0, 0].Value = "bbb";
DataGridViewTextBoxCell TextBoxCell = new DataGridViewTextBoxCell();
this.dataGridView1[0, 1] = TextBoxCell;
this.dataGridView1[0, 1].Value = "some text";
DataGridViewCheckBoxCell CheckBoxCell = new DataGridViewCheckBoxCell();
CheckBoxCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
this.dataGridView1[0, 2] = CheckBoxCell;
this.dataGridView1[0, 2].Value = true;
}
怎样才能使控件初始化过程中正确呈现?
(我在动态添加DataGridViews)。
UPDATE:雅各谢列兹尼奥夫的答案适用于形式,但不是用户控件这正是我需要的...这里是如何重现它:
形式:
private void button3_Click(object sender, EventArgs e)
{
this.Controls.Add(new userCtrl());
}
用户控制:
public partial class userCtrl : UserControl
{
public userCtrl()
{
InitializeComponent();
}
protected override void OnLoad(EventArgs e)
{
ControlsInGridViewColumn();
base.OnLoad(e);
}
public void ControlsInGridViewColumn()
{
//same code as above
}
}
