Populating textboxes from listview. Overload Error

Question

I have a program I wrote. It opens a new window named editItem.xaml. I set the title of the program and the variables of the program. Then I check to see if DialogResult = true and if it does then I refresh the listview with some other code. I can successfully grab the data from the listview to populate the textboxes with:

ei.txtEditEffectiveDate.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[1].ToString();

but the data is not formatted in anyway. So the date comes out as: 06/01/2014 12:00:00

I tried simply putting in the ToString("d"); to change the format but when I do I get an error:

No overload for method 'ToString' takes 1 arguments

And here is my code:

    private void editEntryInstance()
    {
        // Open editItem.xaml
        editItem ei = new editItem();

        // Assign the program a title
        ei.Title = "Edit Entry for Item: " + ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[0].ToString();

        // Get variables of entry
        ei.txtEditItem.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[0].ToString();
        ei.txtEditEffectiveDate.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[1].ToString();
        ei.txtEditTermDate.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[2].ToString();
        ei.txtEditMoq.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[3].ToString();
        ei.txtEditSetupCost.Text = ((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[4].ToString();

        if (ei.ShowDialog().Value)
        {
            // Refresh after editing entry
            refreshInstance();
        }
    }

Any suggestions?

You are trying to apply ToString("d") on a string type value. This ToString overload is available with DateTime type object.

You need to convert your value to a DateTime type object and then apply ToString("d") .

DateTime dt = Convert.ToDateTime(((System.Data.DataRowView)(listView1.SelectedItem)).Row.ItemArray[1]);
ei.txtEditEffectiveDate.Text = dt.ToString("d");

You may need DateTime.ParseExact or DateTime.TryParseExact for parsing string values to DateTime if you the value contains date in custom format.
