DataTable dtDetails = new DataTable();//build datatable...

//add columns...
dtDetails.Columns.Add("Cusip");
dtDetails.Columns.Add("Isin");
dtDetails.Columns.Add("Position");
dtDetails.Columns.Add("Bond Price");

//add rows...
dtDetails.Rows.Add("cusip value");

How do I add rows to the datatable with values in each cell in the appropriate row for the column?

For example; the above code creates a datatable with columns and a row. In the first column of the row it shows "cusip value". I also want to add other texts to other cells for other columns in that row.
How is this done please?

Thanks

ListView Single Range Selection

Echilon25-Mar-08 4:27

25-Mar-08 4:27

I have a ListView, and I'd like to only allow a single range to be selected. I need the equivalent of Java's SINGLE_SELECTION_INTERVAL ( http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/ListSelectionModel.html#SINGLE_INTERVAL_SELECTION ). For example:

If a ListView has 5 rows, #1,#2 could be selected, or #3,#4,#5, or just #3, but not #1,#3,#4.

Is there any way of adding this functionality in C# without getting heavily into rewriting the control?

Well, if you want to find out what process is locking a file you can use this little utility http://www.dr-hoiby.com/WhoLockMe/[^]

That's a tool not a programmatic method so if its the latter you're after it won't help.

Hi All,

I have to listboxes and a button. when the user clicks the button, the selected items from listbox1 will copied into listbox2:

foreach (object o in listBox1.SelectedItems)<br />
<br />
{<br />
<br />
listBox2.Items.Add(o.ToString());<br />
<br />
}

How can i set a control before copieng items. If the selected item(s) from listbox1 already exist in listbox2, that item(s) will not be copied(to avoid duplicate items)????

Thanx.

just a quick note add this to your code and it will work !

Clipboard.SetText(item.ToString());

foreach (object item in listBox1.SelectedItems)
            {
                if (!listBox1.Items.Contains(item))
                    listBox1.Items.Add(item);
                Clipboard.SetText(item.ToString()); 
            }

enum problem in C#

salon25-Mar-08 3:13

I am facing a problem.
I have an enum which further goes as some string values.
Now I have a check or validation for that particular enum type as if it is null, then
display some error message.

But when I give nothing for the particular parameter, it takes the first value from the enum
which is wrong and I do not get the error message at all.

what should I have to do for the validation for null values or when user does not entered any value?
I do not want enum to set the default value as the first one.

I declared this:

public enum HowFullIsGlass<br />
  {<br />
      HalfEmpty,<br />
      HalfFull<br />
  }

and then tried to execute this statement block

HowFullIsGlass hfig ;<br />
if (hfig == null)<br />
{<br />
    Console.WriteLine("Null value");<br />
}

I get this error

Warning 1 The result of the expression is always 'false' since a value of type 'WindowsApplication7.HowFullIsGlass' is never equal to 'null' of type 'WindowsApplication7.HowFullIsGlass?' C:\Users\russell.jones\Documents\Visual Studio 2005\Projects\WindowsApplication7\WindowsApplication7\Form1.cs 26 17 WindowsApplication7

I would be tempted to declare this

public enum HowFullIsGlass<br />
{<br />
    Dunno,<br />
    HalfEmpty,<br />
    HalfFull<br />
}

and declare it as HowFullIsGlass hfig = HowFullIsGlass.Dunno;

then you don't need the null check you can check for Dunno

Just add a value of "Null" to your enum and pass that.

Enums are value types and therefor can never be null.

If you mean that the user provides a string and you try to parse it to get an enum value then I suggest you use System.String.IsNullOrEmpty and act accordingly.

PIEBALDconsult,

IsNullOrEmpty is not recommended as it can throw an exception which you wouldn't expect.

I have only ever seen this bug reproduced in the do-nothing example, not in any real code.

Despite everything, the person most likely to be fooling you next is yourself.

This only applies in a very specific case and, if you move to .NET 3.5, it's been fixed.

Every method that does something like "return someObject == null || someObject.SomeProperty == someValue;" can cause that exception (but only if it's called in a useless loop).
And it's fixed in .NET 2.0 SP1.

How to Set multiple items as selected in a ListBox with c# [modified]

I have a ListBox set as Multiselect. I am populating the table thruough asp.net code. But I am using another dataset to get the items that should be selected. The only item that ends up selected is the last item in the dataset, and I know in several cases there are at least two items that should be selected. The code I am using for setting the selected items is:

DataSet ds1 = SqlHelper.ExecuteDataset(ConnStr, "StoredProd", Parm);

lbRequestTime.SelectionMode = ListSelectionMode.Multiple;

foreach (DataRow row in ds1.Tables[0].Rows)
{
lbRequestTime.SelectedValue = row["PerfTimeId"].ToString();
}

Any help on how to get the Mulitple selected items selected would be great.

Thanks, Doug

Hi,
you can use the following code

<br />
ListItem li;<br />
foreach (DataRow row in ds1.Tables[0].Rows)<br />
{<br />
  li = lbRequestTime.Items.FindByValue(row["PerfTimeId"].ToString());<br />
  if (li != null)<br />
     li.Selected = true;<br />
}<br />

Do let me know if you need more info.
