问题描述
我的 datagridview 有两列([问题]、[答案]).根据已知的问题类型(是/否复选框、文本文本框、FileUpload Button) 我希望列单元格具有相应的控件.
My datagridview has two columns ([Question], [Answer]). Depending on the known question type (Yes/No Checkbox, Text Textbox, FileUpload Button) I want the column cell to have the respective control.
示例
Datagridview 行:
Datagridview Rows:
[问题] 你抽烟吗?[Answer] (YesNo 复选框)[问题] 你几岁了?[Answer] (Text Textbox)[问题] 文档上传 [答案] (FileUpload 按钮) [Question] Do you smoke? [Answer] (YesNo Checkbox) [Question] How old are you? [Answer] (Text Textbox) [Question] Document upload [Answer] (FileUpload Button)<小时>
工作
我以编程方式创建了我的数据网格视图.
Work
I programmatically create my datagridviews.
Private Sub FormatQuestionDgv(ByVal dgv As DataGridView)
Dim ColQ As New DataGridViewTextBoxColumn
Dim ColA As New DataGridViewColumn
'Header text
ColQ.HeaderText = "Question"
ColA.HeaderText = "Answer"
'Name
ColQ.Name = "ColQ"
ColA.Name = "ColA"
'Widths
ColQ.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
ColA.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
'Add columns
With dgv.Columns
.Add(ColQ)
.Add(ColA)
End With
End Sub

问题
正如您在我的工作中看到的,答案列是 DataGridViewColumn
类型.我当时不知道问题类型.因此,我将其声明为普通列而不是 DataGridViewCheckBoxColumn
、DataGridViewTextBoxColumn
、DataGridViewButtonColumn
...
Problem
As you can see in my work, the answer column is of DataGridViewColumn
type. I do not know the question type at that moment. Therefore I declare it as a normal column instead of DataGridViewCheckBoxColumn
, DataGridViewTextBoxColumn
, DataGridViewButtonColumn
...
由于这些与 DataGridViewColumn
的类型不同,我收到以下错误:
Since those are not the same type as DataGridViewColumn
, I get the following error:
如何在 1 个 DataGridViewColumn 中添加不同的控件类型?甚至有可能吗?
How do I go about adding different control types in 1 DataGridViewColumn? Is it even possible?
推荐答案
你看过这些:
在 DataGridViewColumn 中混合单元格类型
一列的DataGridview单元格不能有不同的类型

根据 MSDN 文章...
Following from the MSDN article...
有两种方法可以做到这一点:
There are two ways to do this:
将DataGridViewCell
转换为存在的特定单元格类型.为了例如,将 DataGridViewTextBoxCell
转换为DataGridViewComboBoxCell
类型.创建一个控件并添加到控件集合中DataGridView
,设置它的位置和大小以适合要显示的单元格主持人.
Cast a DataGridViewCell
to a certain cell type that exists. For
example, convert a DataGridViewTextBoxCell
to
DataGridViewComboBoxCell
type.
Create a control and add it into the controls collection of
DataGridView
, set its location and size to fit the cell that to be
host.
以下是一些示例代码,用于说明这些技巧:
Here's some sample code which illustrates these tricks:
private void Form5_Load(object sender, EventArgs e)
{
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;
/*
* First method : Convert to an existed cell type such ComboBox cell,etc
*/
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;
/*
* Second method : Add control to the host in the cell
*/
DateTimePicker dtp = new DateTimePicker();
dtp.Value = DateTime.Now.AddDays(-10);
//add DateTimePicker into the control collection of the DataGridView
this.dataGridView1.Controls.Add(dtp);
//set its location and size to fit the cell
dtp.Location = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Location;
dtp.Size = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Size;
}
