Question How to display the Images column with listview

[Paraman]

Hi Iam using winforms-vs2015-c#. I have small application, and I try to display the listview with images I get struck. Actually the table column contains Images. Also when I display the table datasource to DataGridView the Image columns displays the Images very nice. But I wish to use it from listview

for (int N1 = 0; N1 <= MyDtaTbl.Rows.Count - 1; N1++) {
                    ChkItm = String.Empty;
                    ChkItm = MyDataTbl.Rows[N1]["item_type"].ToString().Trim().ToUpper();
                    Naomi = ChkItm.StartsWith(thisBox.Text);
                    //MessageBox.Show(thisBox.Text);
                    if (Naomi == true) {
                        ListViewItem^ xItem = gcnew ListViewItem(MyDataTbl.Rows[N1]["item_type"].ToString());
                        //xItem.ImageIndex = 0;
                        xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_description"].ToString());
                        xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_code"].ToString());
                        xItem.SubItems.Add(MyDataTbl.Rows[N1]["type_code"].ToString());

                        //MyTries

                        //ListViewItem.ListViewSubItem yItem = new ListViewItem.ListViewSubItem();
                        //xItem.SubItems.Add(yItem);
                        //String MyStr = Convert.ToBase64String(MyDataTbl.Rows[N1]["item_image"]);
                        //Byte[] MyImgBInData = MyDataTbl.Rows[N1]["item_image"];
                        if (MyDataTbl.Rows[N1]["item_image"] != nullptr && MyDataTbl.Rows[N1]["item_image"] != DBNull.Value) {
                            //MyParImg = MyDataTbl.Rows[N1]["item_image"].ToBitmap();
                            //MyParImg = (Bitmap)(MyDataTbl.Rows[N1]["item_image"]);
                            //MyParImg = MyDataTbl.Rows[N1]["item_image"];
                            MyParaObject = MyDataTbl.Rows[N1]["item_image"];
                        }
                        //xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_image"].ToString());
                      //xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_image"]); ????????????????????????? Try to add Image Column to Listview

                        xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_units"].ToString());
                        xItem.SubItems.Add(MyDataTbl.Rows[N1]["item_rate"].ToString());
                        
                        listView1.Items.Add(xItem);
                    }
                }
}

For the record, the inline code tag is for inline code, e.g. if you're telling someone that you used a TextBox control. If you want to post a block of code, used the code tag. I have edited your post accordingly.

There's no such thing as an image column in a ListView. If you want to associate images with items in a ListView, you need to use an ImageList. You should read some relevant documentation, starting here:

ListView.LargeImageList Property (System.Windows.Forms)

Gets or sets the ImageList to use when displaying items as large icons in the control.

learn.microsoft.com

ListView.SmallImageList Property (System.Windows.Forms)

Gets or sets the ImageList to use when displaying items as small icons in the control.

I'm not sure whether you can display images at all if the View is Details, but I haven't used a ListView for a long time, so I'm not sure.
