Re: Adding a total column to datagrid control - C# Discussion Boards

18-Aug-07 9:27

Good evening everyone,
As the subject says, I wonder if there's a possibility to add a column to a datagrid control that calculates (count, sum, or average) multiple columns or rows..
Please advise Rose | [Rose]

You have complete control over the datagrid, so yes, there is a way to add a totals column.

One way would be to add it to your query.

SELECT field1, field2, SUM(field3) FROM...

Another way would be to handle the databinding events and populate the column at runtime.

If you had a table with this structure

col1 col2
1 2
10 20
20 30

then SELECT col1, col2, SUM(col1,col2)...

would produce this:
1,2,3
10,20,30
20,30,50

Of course this only gives you the totals for the rows selected. If you want some other sort of total, then adjust the SQL statement, maybe MAX, or AVE, or whatever is needed.

If you are using a DataSet as data source then you can add an expression column to it.

How do I Encrypt Connection String Password in C# Windows Application

Hi
I have this Sql Authentication connection string which has a username and password.
I added this connection string to Application Settings and the corresponding app.config item
was added to my project automatically. But now that i want to access the app.config file
in my codes,ConfigurationSection,ConfigurationManager and other related classes,properties and methods
are not available.I read many articles on this subject but i havent been able to do the encryption so far.
The other question is wether the encryption needs to be done once or should it be done every time
the application runs? Is it be possible to set this encrypted connection as a SqlConnection's connection
string or the assignment must be done prior to encryption?

please help!

thanks

Native docking in Winforms MDI app?

Ravi Bhavnani18-Aug-07 7:27

I have a WinForms MDI app that has a docked navigation panel at the left edge. However, when I create MDI child windows, the main window seems to ignore the presence of the navigation panel and uses its entire client area to layout the child windows. Is it possible to override the MDI container's layout logic and reduce its client area by the space occupied by the navigation panel?

I tried doing this in the main window's Load handler, but it didn't seem to have any effect. (I understand that this would only set the initial client area, which may need to be recomputed in a SizeChanged handler).

private void MainFrm_Load
  (object sender,
   EventArgs e)
{
   // Nav panel test
   NavigatorFrm nf = new NavigatorFrm();
   nf.MdiParent = this;
   nf.Dock = DockStyle.Left;
   nf.Show();
   this.ClientSize = new Size (this.ClientSize.Width - nf.Width, this.ClientSize.Height);
}

Thanks,

If still anyone is looking for this, just override the control's DisplayRectangle property. Just mentioned as I was looking for the same till a few days ago.

That is a nice article you linked to. I am wondering why it was voted down a bit... It may be an older article from 2002, but the information looks still useful.

exactly. and use a timer if u want it to look like a clock Smile | :)

there are no facts, only interpretations

18-Aug-07 9:42

And use the conditional operator ?: to format it like a real clock Smile | :)

int Hours = ((YourTimeVariable / 1000) / 3600);
int Minutes = ((YourTimeVariable / 1000) / 60) - (Hours * 60);
int Seconds = ((((YourTimeVariable / 1000)) - (Minutes * 60)) - (Hours * 3600));

strHours = Hours < 10 ? "0" + Hours.ToString() : Hours.ToString();
strMinutes = Minutes < 10 ? "0" + Minutes.ToString() : Minutes.ToString();
strSeconds = Seconds < 10 ? "0" + Seconds.ToString() : Seconds.ToString();

Time_TextBox.Text = strHours + ":" + strMinutes + ":" + strSeconds;
