Hi Javier,

Have a look at the help topic on data formatting which should give you the answers.
If you need further help though, then just let me know

That help topic refers to GridView and I need to format columns in ListView. Does it apply as well?

Thanks,

Hi Javier,

My apologies for giving you a link to the incorrect topic.
You can't pass a list view column a format, but you could subscribe (for exmaple) to the VisualItemFOrmatting event to format the text
this.radListView1.VisualItemFormatting += new ListViewVisualItemEventHandler(radListView1_VisualItemFormatting);

void radListView1_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)
{
 
}

There may be other ways too depending on your requirements. Let me know if you need more information though

Hi Javier,

Richard's suggestion will work in SimpleView and IconView since the items in these two views are simple. However, the visual items in DetailView are complex and contain a number of cells, each with a different value. Therefore, to format the data in cells that belong to a given column, you should use the CellFormatting event. The following code snippet demonstrates how you can format the values of type DateTime in the second column:
public partial class Form1 : RadForm
{
    public Form1()
    {
        InitializeComponent();
         
        this.radListView1.Columns.Add("Column1");
        this.radListView1.Columns.Add("Column2");
        this.radListView1.ViewType = ListViewType.DetailsView;
 
        for (int i = 0; i <= 100; i++)
        {
            this.radListView1.Items.Add("Item " + i, DateTime.Now.AddHours(i));
        }
 
        this.radListView1.CellFormatting += new ListViewCellFormattingEventHandler(radListView1_CellFormatting);
    }
 
    void radListView1_CellFormatting(object sender, ListViewCellFormattingEventArgs e)
    {
        DetailListViewDataCellElement dataCell = e.CellElement as DetailListViewDataCellElement;
 
        if (dataCell != null && dataCell.Data == this.radListView1.Columns[1])
        {
            dataCell.Text = ((DateTime)dataCell.Row[1]).ToShortTimeString();
        }
    }
}

I hope this will help you. Feel free to ask if you have any further questions.
