blocks|key|1481310|text|您给出了答案：-2将自动调整列的大小到列标题中的文本的长度，-1将自动调整到列中最长的项目。All+according+to+MSDN。但请注意，在-1的情况下，您需要在添加项之后设置列宽。因此，如果添加新项，还需要根据ListView控件中的数据分配要自动调整大小的列(或多个列)的width属性。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1481311|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/system.windows.forms.columnheader.width.aspx^0|32|8|1A|L|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]]|D|@$9|Q|A|R|1|S]]|E|$]]|$1|F|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

You gave the answer: -2 will autosize the column to the length of the text in the column header, -1 will autosize to the longest item in the column. <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.columnheader.width.aspx" rel="noreferrer">All according to MSDN</a>. Note though that in the case of -1, you will need to set the column width after adding the item(s). So if you add a new item, you will also need to assign the width property of the column (or columns) that you want to autosize according to data in <code>ListView</code> control.

blocks|key|1481349|text|我做了一个程序，多次清除并重新填充我的列表视图。由于某种原因，每当我添加宽度为-2的列时，我都会遇到第一列太长的问题。为了解决这个问题，我创建了这个方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1481350|private+void+ResizeListViewColumns(ListView+lv)
{
++++foreach(ColumnHeader+column+in+lv.Columns)
++++{
++++++++column.Width+=+-2;

}|code-block|syntax|javascript|1481351|这个方法的伟大之处在于，您几乎可以将其放在任何位置来调整所有列的大小。只需传入ListView即可。|offset|length|style|CODE|1481352|entityMap^0|0|0|13|8|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I made a program that cleared and refilled my listview multiple times. For some reason whenever I added columns with width = -2 I encountered a problem with the first column being way too long. What I did to fix this was create this method.

<pre><code>private void ResizeListViewColumns(ListView lv)
{
 foreach(ColumnHeader column in lv.Columns)
 {
 column.Width = -2;
 }
}
</code></pre>

The great thing about this method is that you can pretty much put this anywhere to resize all your columns. Just pass in your <code>ListView</code>.

blocks|key|1481555|text|还有另一个有用的方法，称为AutoResizeColumn，它允许您使用所需的参数自动调整特定列的大小。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1481556|你可以这样称呼它：|1481557|listview1.AutoResizeColumn(1,+ColumnHeaderAutoResizeStyle.ColumnContent);

There is another useful method called <code>AutoResizeColumn</code> which allows you to auto size a specific column with the required parameter.

You can call it like this:

<pre><code>listview1.AutoResizeColumn(1, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(2, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(3, ColumnHeaderAutoResizeStyle.HeaderSize);

blocks|key|1481657|text|如果您在任何父面板(ListView+dock+fill)中有ListView，您可以使用简单的方法...|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1481658|private+void+ListViewHeaderWidth()+{

If you have ListView in any Parent panel (ListView dock fill), you can use simply method...

 foreach (ColumnHeader header in listViewInfo.Columns)
 {
 header.Width = HeaderWidth;

blocks|key|1266797|text|在Fredrik的回答上扩展一下，如果你想动态设置列的自动调整宽度，例如:将第一列的自动调整宽度设置为70：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1266798|myListView.Columns[0].AutoResize(ColumnHeaderAutoResizeStyle.None);
myListView.Columns[0].Width+=+70;
myListView.Columns[0].AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);|code-block|syntax|javascript|1266799|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Expanding a bit on Fredrik's answer, if you want to set the column's auto-resize width on the fly
for example: setting the first column's auto-size width to 70:

<pre><code>myListView.Columns[0].AutoResize(ColumnHeaderAutoResizeStyle.None);
myListView.Columns[0].Width = 70;
myListView.Columns[0].AutoResize(ColumnHeaderAutoResizeStyle.ColumnContent);
</code></pre>

blocks|key|1481454|text|此解决方案将首先根据列数据调整列的大小，如果调整后的宽度小于标题大小，它将调整列的大小以至少适合标题。这是一个相当丑陋的解决方案，但它是有效的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1481455|lstContacts.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);
colFirstName.Width+=+(colFirstName.Width+<+60+?+60+:+colFirstName.Width);

colEmail.Width+=+(colEmail.Width+<+40+?+40+:+colEmail.Width);|code-block|syntax|javascript|1481456|lstContacts是ListView。colFirstName是一列，其中60是适合标题所需的宽度。等。|1481457|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

This solution will first resize the columns based on column data, if the resized width is smaller than header size, it will resize columns to at least fit the header. This is a pretty ugly solution, but it works.

<pre><code>lstContacts.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);
colFirstName.Width = (colFirstName.Width &lt; 60 ? 60 : colFirstName.Width);
colLastName.Width = (colLastName.Width &lt; 61 ? 61 : colLastName.Width);
colPhoneNumber.Width = (colPhoneNumber.Width &lt; 81 ? 81 : colPhoneNumber.Width);
colEmail.Width = (colEmail.Width &lt; 40 ? 40 : colEmail.Width);
</code></pre>

lstContacts is the ListView.
colFirstName is a column, where 60 is the width required to fit the title.
Etc.

You can use something like this, passing the ListView you want in param

<pre><code> private void AutoSizeColumnList(ListView listView)
 {
 //Prevents flickering
 listView.BeginUpdate();

 Dictionary&lt;int, int&gt; columnSize = new Dictionary&lt;int,int&gt;();

 //Auto size using header
 listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);

 //Grab column size based on header
 foreach(ColumnHeader colHeader in listView.Columns )
 columnSize.Add(colHeader.Index, colHeader.Width);

 //Auto size using data
 listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);

 //Grab comumn size based on data and set max width
 foreach (ColumnHeader colHeader in listView.Columns)
 {
 int nColWidth;
 if (columnSize.TryGetValue(colHeader.Index, out nColWidth))
 colHeader.Width = Math.Max(nColWidth, colHeader.Width);
 else
 //Default to 50
 colHeader.Width = Math.Max(50, colHeader.Width);
 }

 listView.EndUpdate();
 }
</code></pre>

blocks|key|1267013|text|还值得注意的是，如果不先更改属性，ListView可能无法按预期显示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1267014|myListView.View+=+View.Details;+//+or+View.List|code-block|syntax|javascript|1267015|对我来说，由于某种原因，Visual+Studio似乎将其默认为View.LargeIcon，所以在它被更改之前什么都不会出现。|1267016|完成代码以在ListView中显示单列，并为垂直滚动条留出空间。|1267017|lisSerials.Items.Clear();

It is also worth noting that ListView may not display as expected without first changing the property:

<pre><code>myListView.View = View.Details; // or View.List
</code></pre>

For me Visual Studio seems to default it to View.LargeIcon for some reason so nothing appears until it is changed.

Complete code to show a single column in a ListView and allow space for a vertical scroll bar.

<pre><code>lisSerials.Items.Clear();
lisSerials.View = View.Details;
lisSerials.FullRowSelect = true;

// add column if not already present
if(lisSerials.Columns.Count==0)
{
 int vw = SystemInformation.VerticalScrollBarWidth;
 lisSerials.Columns.Add("Serial Numbers", lisSerials.Width-vw-5);
}

foreach (string s in stringArray)
{
 ListViewItem lvi = new ListViewItem(new string[] { s });
 lisSerials.Items.Add(lvi);
}
</code></pre>

How can I set the column width of a c# winforms <code>listview</code> control to auto. Something like width = -1 / -2 ?
