Dear All, ListView column width does not obey the width setting as shown in the following screen captures. Can anybody help me solve this problem? I set the width of the date column to 426. The form in runtime.

Hi @BenTam-3003 , Welcome to Microsoft Q&A, After my test, You probably have adaptive width enabled somewhere. For example: listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize); It is very likely that you made the listview adaptive to the matrix. try setting it manually listView.Columns[0].Width = 465; This way it turns off autoresize。 Best Regards, Jiale If the answer is the right solution, please click " Accept Answer " and kindly upvote it.

Hi @BenTam-3003 , Welcome to Microsoft Q&A,

You probably have adaptive width enabled somewhere.

For example:

listView.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);

It is very likely that you made the listview adaptive to the matrix.

try setting it manually

listView.Columns[0].Width = 465;

This way it turns off autoresize。

Hi @Jiale Xue - MSFT

I have tried your suggestion without success. Should I put the statement in another place?

As shown, if something later causes autoresize, it will automatically change.

I also noticed a peculiarity that your listview doesn't seem to have table lines. Did you use some custom style on it? That might be causing the problem. Can you show the relevant code of the listview module?

Hi @Jiale Xue - MSFT

The code is copied from a webpage. I forget what site. The code only contains a "InititalizeResizingListViews" function. I create the a class to contain. The is shown below. Since I have modified the code of InitializeResizingListView2, I am trying to restore it. However, I don't know whether I remember correctly.

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace NewTims { public partial class Test_Form : Form { //private ListView resizingListView2 = new ListView(); private Button resizeButton = new Button(); public Test_Form() { InitializeComponent(); } private void InitializeResizingListView2() { // Set location and text for button. resizeButton.Location = new Point(100, 15); resizeButton.Text = "Resize"; // Set the ListView to details view. resizingListView2.View = View.Details; //Set size, location and populate the ListView. resizingListView2.Size = new Size(200, 100); resizingListView2.Location = new Point(40, 40); resizingListView2.Columns.Add("HeaderSize"); resizingListView2.Columns.Add("ColumnContent"); ListViewItem listItem1 = new ListViewItem("Short"); ListViewItem listItem2 = new ListViewItem("Tiny"); listItem1.SubItems.Add(new ListViewItem.ListViewSubItem( listItem1, "Something longer")); listItem2.SubItems.Add(new ListViewItem.ListViewSubItem( listItem2, "Something even longer")); resizingListView2.Items.Add(listItem1); resizingListView2.Items.Add(listItem2); // Add the ListView and the Button to the form. this.Controls.Add(resizingListView2); this.Controls.Add(resizeButton); } } }

Hi @BenTam-3003 , You can find that it resets your size.

resizingListView2.Size = new Size(200, 100);

Hi @BenTam-3003 ,

Maybe you could use the correct symbol.

Hi @Jiale Xue - MSFT

After adding "index: 0" and changing the "( )" to "[ ]", the error disappears.
