What type of project is this, Windows or Web? The answer will depend a great deal on this.

Set EnableViewState=true on the control or set the SelectedIndex during your postback

You are using some JavaScript library to create the dropdown. You are not using ASP.NET. If you want accurate and helpful answers to your questions you must provide ALL of the relevant details. I have no idea what Ext.form.ComboBox is.

Set AutoGenerateColumns to false and add the columns via the wizard or manually through code.

Set the column name to what you want in your SELECT statement.

SELECT fieldname columnname ...

First, set AutoGenerate Columns to false.

Second, set ColumnWidthType to numeric or SizeToHeader as required.

Third, set column width like below:

DataGridViewColumn column = dataGridView.Columns[0];
column.ItemStyle.Width = 100;

Next, set column header text to what you want, if required:

column[0].HeaderText = "ID";

You could use the Process.Start("http://www........") to fire off a default browser session external to the application.

There are some exceptions which get swallowed by Visual Studio. E.g. exceptions in Form_Load or Form_Shown are swallowed, when you do not have a try...catch block exactly in those functions. I do not know a useful documentation on that feature.
Furthermore, some exceptions - also with the events mentioned above - could be swallowed on 64bit systems even in a "Release" executable, as documented in http://blog.paulbetts.org/index.php/2010/07/20/the-case-of-the-disappearing-onload-exception-user-mode-callback-exceptions-in-x64/[^].

String format for MAC-address

Mc_Topaz24-Mar-11 4:22

24-Mar-11 4:22

I would like to convert a string representing a MAC-address in one format to an other format. I thought I could use the String.Format() method to do this, but I don't get what I want.

I'm looking for this sequence flow:

Soruce: 00204A846187
Result: 00-20-4A-84-61-87

My code:

string mac1 = "00204A846187";
string mac2 = String.Format("{0:##-##-##-##-##-##}", mac1);
Console.WriteLine(mac1 + " converted to: " + mac2);

When I run that I don't get what I want. mac2 is the same as mac1 variable... D'Oh! | :doh:

I hope I missed something because I don't want to loop through every other charecter and append "-" manually.

Any suggestions?

the code to do that would be shorter than your above message is.

strings aren't the primary choice for representing data, and string.Format is pretty good at turning non-strings into a string.
having two different string representations for anyhting is to be avoided, so rather than convert I suggest you avoid the dash-less format entirely.
