如何：设置 Windows 窗体 DataGridView 控件的大小调整模式

2008-08-18

更新：2007 年 11 月

下面的过程演示一些常见方案，用于自定义或组合 DataGridView 控件及控件中的特定列可用的大小调整选项。

创建具有固定宽度的列

将 AutoSizeMode 属性设置为 None，Resizable 属性设置为 False，ReadOnly 属性设置为 true，并将 Width 属性设置为适当的值。

Dim idColumn As New DataGridViewTextBoxColumn()
idColumn.HeaderText = "ID"
idColumn.AutoSizeMode = DataGridViewAutoSizeColumnMode.None
idColumn.Resizable = DataGridViewTriState.False
idColumn.ReadOnly = True
idColumn.Width = 20

DataGridViewTextBoxColumn idColumn =
    new DataGridViewTextBoxColumn();
idColumn.HeaderText = "ID";
idColumn.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
idColumn.Resizable = DataGridViewTriState.False;
idColumn.ReadOnly = true;
idColumn.Width = 20;

创建可调整大小以适应其内容的列

将 AutoSizeMode 属性设置为基于内容的大小调整模式。

Dim titleColumn As New DataGridViewTextBoxColumn()
titleColumn.HeaderText = "Title"
titleColumn.AutoSizeMode = _
    DataGridViewAutoSizeColumnMode.AllCellsExceptHeader

DataGridViewTextBoxColumn titleColumn =
    new DataGridViewTextBoxColumn();
titleColumn.HeaderText = "Title";
titleColumn.AutoSizeMode =
    DataGridViewAutoSizeColumnMode.AllCellsExceptHeader;

为具有不同的大小和重要性的值创建填充模式列

将 DataGridView.AutoSizeColumnsMode 属性设置为 Fill，以便为不重写此值的所有列设置大小调整模式。将这些列的 FillWeight 属性设置为与内容的平均宽度成一定比例的值。设置重要列的 MinimumWidth 属性以确保显示部分内容。

dataGridView1.AutoSizeColumnsMode = _
    DataGridViewAutoSizeColumnsMode.Fill

Dim subTitleColumn As new DataGridViewTextBoxColumn()
subTitleColumn.HeaderText = "Subtitle"
subTitleColumn.MinimumWidth = 50
subTitleColumn.FillWeight = 100

Dim summaryColumn As new DataGridViewTextBoxColumn()
summaryColumn.HeaderText = "Summary"
summaryColumn.MinimumWidth = 50
summaryColumn.FillWeight = 200

Dim contentColumn As new DataGridViewTextBoxColumn()
contentColumn.HeaderText = "Content"
contentColumn.MinimumWidth = 50
contentColumn.FillWeight = 300

dataGridView1.AutoSizeColumnsMode =
    DataGridViewAutoSizeColumnsMode.Fill;

DataGridViewTextBoxColumn subTitleColumn =
    new DataGridViewTextBoxColumn();
subTitleColumn.HeaderText = "Subtitle";
subTitleColumn.MinimumWidth = 50;
subTitleColumn.FillWeight = 100;

DataGridViewTextBoxColumn summaryColumn =
    new DataGridViewTextBoxColumn();
summaryColumn.HeaderText = "Summary";
summaryColumn.MinimumWidth = 50;
summaryColumn.FillWeight = 200;

DataGridViewTextBoxColumn contentColumn =
    new DataGridViewTextBoxColumn();
contentColumn.HeaderText = "Content";
contentColumn.MinimumWidth = 50;
contentColumn.FillWeight = 300;
