[1.0/1.1] Adding items to Columns

[eranga262154]

Hi all,

I've created two columns on the list view as follows.

			ColumnHeader colHed;

		// Header one
			colHed = new ColumnHeader();
			colHed.Text = "Name";
			colHed.Width = 100;
			this.lwDetails.Columns.Add(colHed);

		// Header two
			colHed = new ColumnHeader();
			colHed.Text = "Address";
			colHed.Width = 200;
			this.lwDetails.Columns.Add(colHed);

Then on a separate function I try to add data to those columns. Name and address of a one person store in a string array named items. I try to add data as follows.

			this.lwDetails.Items.Add(items[0]);
			this.lwDetails.Items.Add(items[1]);

lwDetails is my list view. In this case name and address are added to the same column. How can I correct it.

Thanks,

Each item occupies a row in the ListView. If you want to fill more columns on a row then you have to add subitems to that item.

Use a ListViewItem object to add your SubItems.

private void Form1_Load(object sender, EventArgs e)
{
    ColumnHeader colHed;
 
    // Header one
    colHed = new ColumnHeader();
    colHed.Text = "Name";
    colHed.Width = 100;
    this.lwDetails.Columns.Add(colHed);
 
    // Header two
    colHed = new ColumnHeader();
    colHed.Text = "Address";
    colHed.Width = 200;
    this.lwDetails.Columns.Add(colHed);
 
    // Setup Listivew stuff
    this.lwDetails.View = View.Details;
    this.lwDetails.FullRowSelect = true;
    this.lwDetails.HideSelection = false;
    this.lwDetails.MultiSelect = false;
 
    // load some data
    ListViewItem lvwItem;
    lvwItem =this.lwDetails.Items.Add(new ListViewItem("Test1"));
    lvwItem.SubItems.Add("SubItem1");
    lvwItem = this.lwDetails.Items.Add("Test2");
    lvwItem.SubItems.Add("SubItem2");
 
}

// load some data
    ListViewItem lvwItem;
    lvwItem =this.lwDetails.Items.Add(new ListViewItem("Test1"));
    lvwItem.SubItems.Add("SubItem1");
    lvwItem = this.lwDetails.Items.Add("Test2");
    lvwItem.SubItems.Add("SubItem2");

I'm not clear what happened on this code, I mean how to find the "Name" column to add the relevant data to it. And "Address" column also. Can you explain it little more.

"SubItem1" and "SubItem2" are the text of the subitems being added.

By setting the lvwItem object to the resulting .Add of the new listviewitem we get a object reference set to that exact item/row. Using the object variable we can access the properties and methods of the row. .SubItems.Add is the method for adding new subitems/text to the other secondary columns.

Oki, I got the point. And also I no need to set the Details property of the ListView, since I can set it on the Properties dialog box. http://www.vbforums.com/showthread.p...96#post3108596

Yes that is true but I was doing it for a demo and as its my preference to code in the setup of the controls instead of property wwindow property setting changes. Explicit code setup is just a matter of personal preference.

That link goes back to your original post?

Thanks Rob, I got the point.

And sorry, that link put by mistake.
