Not very clear what matters here <code>C++Cli</code> tag, but: 

I presume that if you're talking about a columns in <code>ListView</code>, you're in details view of the control. There is no builtin Hide/Show column way in <code>ListView</code>, as much as I'm aware of, so one of solutions can be just remove that column form UI. 

To do that in most smooth way possible just call your <code>ListView</code> column regeneration code in between 

<pre><code>listView.SuspendLayout(true);

/*Manipulate column here*/

listView.ResumeLayout();
</code></pre>

The data which is visible on <code>ListView</code> always remains "in your hands", so at the moment you will decide to show the column again, just show the column and fill <code>ListView</code> again.

Hope this helps.

I was looking for a way to do the same thing which brought me here.
I'm not sure if there is a better way of doing it, so I use following workaround.
If you need to add a value to a <code>Listview</code> Item but don't want to show it, you can use a subitem index greater than the total column count. This way, even though the value exists it is not visible to the user.

How to hide/show listview columns

C#, .NET framework 3.5.

It is easy to hide and show listview columns, if you use the listview in “virtual mode”. In “virtual mode”, you are responsible for filling the listviewitems with data. This makes it possible to put the correct data in the correct column.

Let me demonstrate:
Create a form, and add a listview control and a button control.
Add 3 columns to the listview control.
Set the “view” property of the listview control to “Details”.
Set the “VirtualMode” property of the listview control to “True”.
Set the “VirtualListSize” property of the listview control to “100”.
Add a bool to the form:

<pre><code>private bool mblnShow = true;
</code></pre>

Add the event “RetrieveVirtualItem” for the listview control, and add the following code:

<pre><code>ListViewItem objListViewItem = new ListViewItem();
objListViewItem.Text = "Item index: " + e.ItemIndex.ToString();
if (mblnShow) objListViewItem.SubItems.Add("second column: " + DateTime.Now.Millisecond.ToString());
objListViewItem.SubItems.Add("third column: " + DateTime.Now.Millisecond.ToString());
e.Item = objListViewItem;
</code></pre>

Add the “Click” event for the button control, and add the following code:

<pre><code>mblnShow = !mblnShow;
if (mblnShow &amp;&amp; !this.listView1.Columns.Contains(this.columnHeader2)) this.listView1.Columns.Insert(1, this.columnHeader2);
else if (!mblnShow &amp;&amp; this.listView1.Columns.Contains(this.columnHeader2))
 this.listView1.Columns.Remove(this.columnHeader2);
</code></pre>

Run the application, and press the button to show and hide the second column.

Please note that running a listview in virtual mode will throw an error if you put data in the items collection. There is much more the know about virtual mode, so I suggest reading about it before using it.

blocks|key|2935736|text|您应该使用DataTemplateSelector在列表视图中动态隐藏和显示列或行。在官方文档中有一篇有趣的文章。https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/templates/data-templates/selector|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2935737|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/templates/data-templates/selector^0|1L|2X|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You should use DataTemplateSelector to hide and show dynamically a column or a row in a listview. There is an intersting article in the official documentation. <a href="https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/templates/data-templates/selector" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/templates/data-templates/selector</a>

If you have only one column, a second empty column shows up to fill the extra space to the right. To hide this empty column, implement the listview resize event. In there do the following.

<pre><code>m_lstItems.Columns[0].Width = m_lstItems.Width - 5;
</code></pre>

This will effecitvely hide the extra empty column and instead have the first column take up all the space in the listview.

How can I hide a column in a <code>ListView</code> control, without setting the column <code>Width</code> property to <code>0</code>?

Also, can I lock the <code>Width</code> of a column?
