I don't know whether there is a directive or not but you can check whether the control is at design time or not. See here: Detecting Design-time in C#[^]

Neither of the methods there worked for me, but it allowed me to use different search criteria in google, and found an answer right here on CP:

I see you solved this, let me just add that the designer has become a bad joke, it runs about half of your code, and if that code relies on other code that it doesn't bother to run, it crashes. MS says this is a feature.

The designer is definitely a like bad dream once you start to do anything more complicated than simply accepting the default form in a new WinForms app, but You're forced to use it if you want a reasonable chance at designing a form in a short amount of time. Are there any alternatives that don't include the acronym "WPF"?

Hi,
my question is that how we can put a Hyperlink in the MessageBox in C#.
Thanks,

You can't do it with standard messagebox, you need to develop your own and use linklabel control

Hi friends,
I have created voting application,i have almost finished it but i should check that one user should vote once by getting his session any idea for this....
Checking IP address will prevent other users voting so i need to take user browsers session or some other ideas for this method.....

First of all, we have an ASP.NET forum, why did you not ask there ?
Second, there's no way to do this. A new session is created when someone reconnects to your site, and so an IP address is your only option, and that won't work if someone has a dynamic IP and reconnects to the web. The only way for this level of control is to issue people with a login and let every login only work once.

Hi,
I'm currently in the planning stages of a medium sized application.
The essence of this application will be a website, similar to hotel booking sites like booking.com
I'm deciding what data access to use...
I've narrowed it down to two options - nHibernate, or Microsoft Data Access Application Block
In what situation would either of those be a better option?

Hello,
Have you tried using the
ShowDialog() method when you are opening the second window from within the form1's code? E.g.:
private void button1_Clicked(object sender, EventArgs e)
{
Form SecondForm = new SecondForm();
SecondForm.ShowDialog();
}
This will open the second form on-top of the first form, and the main form cannot be accessed until the second form has been disposed.
Hope this helps.
j.t.

Hi All,
I Want To Convert ToolStripMenuItem Object To Label....
Such As,
private void ChangeSetting(object sender,EventArgs e)
{
Label L=(Label)sender;
}
but I Cannot Do That. Please Help Me
Thank You All

You cannot cast ToolStripMenuItem to Label, if you want to get/set the text of the menu item use the Text property.

i'm trying to do as the title says...
im using a DataTable and add DataRow[] in it and every DR contains a column type of a class i have made. The class have 2 properties, a string and an int. Then i bind that DataTable to DataGridView. Now problem is that its showing the class name with Namespace and it should. But i want it to show that string property in that column.
Its exactly same like ComboBox or ListBox binding.
I tried with DataPropertyName but all columns appear blank
dataGridView.Columns[0].DataPropertyName = "Name";
full code
DataTable tmp_dt = new DataTable();
tmp_dt.Columns.Add("Info", typeof(XYZclass));
DataRow tmp_dr = tmp_dt.NewRow();
tmp_dr["Info"] = new XYZclass("a string Param to set the string in class");
tmp_dt.Rows.Add(tmp_dr);
dataGridView.DataSource = tmp_dt;
dataGridView.Columns[0].DataPropertyName = "Name";
any idea ?

You need to override the ToString() or create an implicit operator string (can't remember which one). Then, your class will correctly display wich ever string you want to be displayed in the datagridview.
