我创建了一个大约12个项目的CheckedListBox。我想动态创建Textboxes以在每次选择Item时显示并接受表单上用户的输入值。当最终选择Button时,Textboxes值将与Selected Items Values相关联,以存储到某个Sql数据库表中。
到目前为止,我能够做到的是,即使我从列表框中选择了其他项目,也会显示一个文本框。以下是我的代码
private void checkedList_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (e.NewValue == CheckState.Checked)
{
int n = 6;
selectedList.Items.Add(checkedList.SelectedItem.ToString());
for (int x=0; x < checkedList.SelectedItems.Count; x++)
{
TextBox[] txtBoxes = new TextBox[n];
for (int i = 0; i < n; i++)
{
txtBoxes[i] = new TextBox();
}
for (int i = 0; i < n; i++)
{
this.Controls.Add(txtBoxes[i]);
txtBoxes[i].Location = new Point(450, 100);
txtBoxes[i].Size = new System.Drawing.Size(25, 20);
txtBoxes[i].Validating += new CancelEventHandler(txt_Validating);
}
}
}
else
{
selectedList.Items.Remove(checkedList.SelectedItem.ToString());
}
}
private void InitializeMyListBox()
{
for (int x = 0; x < selectedList.Items.Count; x++)
{
selectedList.SetSelected(x, true);
}
// Force the ListBox to scroll back to the top of the list.
selectedList.TopIndex = 0;
}
我做错了什么?
你能帮忙解决这个问题。

您已为所有TextBox设置了相同的位置。 尝试设置这样的东西:
txtBoxes[i].Location = new Point(450 + i*20, 100);
