.net 如何以编程方式使 ListView 的列自动调整大小？

How can I make a ListView's columns auto-resize programmatically?

提问by Luke

I've found some examples using the Win32 api or simulating the ^+ button combination (ctrl-+) using SendKeys, but at least with the SendKeys method the listview grabs the cursor and sets it to an hourglass until I hit the start button on my keyboard. What is the cleanest way to do this?

我找到了一些使用 Win32 api 或使用 SendKeys模拟 ^+ 按钮组合（ctrl- +）的示例，但至少使用 SendKeys 方法，列表视图会抓取光标并将其设置为沙漏，直到我按下键盘上的开始按钮. 什么是最干净的方法来做到这一点？

Looks like a call to myListView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent)will do what you want. I would think, just call it after adding an item.

看起来像一个电话myListView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent)会做你想做的事。我想，只需在添加项目后调用它。

According to MSDN, if you set the column width to -1 then it will autosize to the widest item

根据MSDN，如果您将列宽设置为 -1，那么它将自动调整为最宽的项目

loop through all columns and set width to -1 after adding content.

添加内容后循环遍历所有列并将宽度设置为 -1。

After adding the following routine to your code then call it from any procedure/function. Do not use it in your "Form_Load" procedure though. Only call it after you have added an item to your ListView (or if you are making multiple additions, call it once at the end of all the additions):

将以下例程添加到您的代码后，然后从任何过程/函数调用它。但是不要在“Form_Load”过程中使用它。仅在将项目添加到 ListView 后才调用它（或者如果您要进行多次添加，请在所有添加结束时调用一次）：

    Private Sub AutoSizeListViewColumns(oListView As ListView)
        Dim nCol As Integer = 0
        SuspendLayout()
        For nCol = 0 To (oListView.Columns.Count - 1)
            oListView.Columns(nCol).Width = -1  'forces autosizing on column
        Next
        oListView.Refresh()
        ResumeLayout()
    End Sub
