Hi,

I have a ListViewItem with 3 columns (Currency, Buy, Sell). I want to show the rate in Buy/Sell Columns base on the exchange type i get from the source table.
Could someone provide some clues on how to do this? Below is my code.
Currently everything displays on Buy column.

public void getExchangeRates()
{
lsvExchangeRate.Clear();
lsvExchangeRate.Columns.Add("Currency", 100, HorizontalAlignment.Left);
lsvExchangeRate.Columns.Add("Buy", 100, HorizontalAlignment.Left);
lsvExchangeRate.Columns.Add("Sell", 100, HorizontalAlignment.Left);

try
{
List<getexchangeratesvo> geRate = erBAL.getExchangeRatesBAL().ToList();

foreach (getExchangeRatesVO grVO in geRate)
{
ListViewItem myItem = new ListViewItem(grVO.currencyName);
if (grVO.exchangeType == "Buy")
{
myItem.SubItems.Add(grVO.exchangeRate.ToString());
lsvExchangeRate.Items.Add(myItem);
}
else
{
myItem.SubItems.Add(grVO.exchangeRate.ToString());
lsvExchangeRate.Items.Add(myItem);
}
}
}

Hi.

I currently use the following extension methods

C#

public static partial class ListViewSubItemExtensions
{
    public static void SetText(this ListViewItem.ListViewSubItemCollection self,
                                int columnIndex, string text)
    {
        while (self.Count <= columnIndex)
            self.Add(string.Empty);

        self[columnIndex].Text = text;
    }
    public static void SetText<T>(this ListViewItem.ListViewSubItemCollection self,
                                int columnIndex, T value)
    {
        SetText(self, columnIndex, value.ToString());
    }
    public static void SetText(this ListViewItem.ListViewSubItemCollection self,
                                ColumnHeader column, string text)
    {
        SetText(self, column.Index, text);
    }
    public static void SetText<T>(this ListViewItem.ListViewSubItemCollection self,
                                ColumnHeader column, T value)
    {
        SetText(self, column.Index, value.ToString());
    }
}

the body of your loop would become:

ListViewItem myItem = new ListViewItem(grVO.currencyName);

if (grVO.exchangeType == "Buy")
    myItem.SubItems.SetText(1, grVO.exchangeRate);
else
    myItem.SubItems.SetText(2, grVO.exchangeRate);

lsvExchangeRate.Items.Add(myItem);

Regards,
Daniele.
