DataGridView.Rows.DefaultCellStyle.BackColor will do that.

I need to print the content of a data grid view.
Now i am using the DGV Printer: DGV Printer Class[^]

But i neet to print only some columns of the data grid view, columns specified by the user.
The DGV Printer prints all the content (all columns), so i can't specify which column must be print. How can i solve this problem ?

Well if simply you want to print some information and to neglect other, the first solution that hits the mind is to process all records and filter out specific columns. Then print that shortened version of information.

I don't know squat about the printer tool but have you tried setting the unwanted columns visible property befor printing.

DataGridView navigating to Child Rows

Hi there,

I am relatively new to .Net programming. I've been using the DataGrid to display my Datatables and i really like the way you can easily navigate to child rows in child tables that you've set up in the DataRelations.

But the more I used it the more i found out about its drawbacks and came across the DataGridView. This has been introduced since VS2005 and the .Net 2.0 framework. Now it has many appealing new functions which are very useful to me. But so far i have not been able to find a way to navigate as easily as with the DataGrid.

From examples i have found, to relate the DataGridView to a source you have to use the DataBindings class. This all seems like alot more effort than with the DataGrid where you would just set the .DataSource property.

So my question is, "Is there an equivalent to the .NavigateTo() and .NavigateBack() functions of the DataGrid in the DataGridView? If there isn't, has a common practice of achieving similiar results been found?"

I hope to hear from someone soon,

AddInCustomAction not working properly

Hi,

I have write an AddInCustomAction that must be performed before the Installation.
I did something like:

public override void Install(IDictionary stateSaver)
{
   ///
   //here is the code that should run before the installation
   // pseudo code:
   // if (MyFile.txt exist)
   //    remove_file();
   ///

   base.Install(stateSaver);
}

This doesn't work properly.
the file MyFile.txt exists (and so should be removed)
but after installation it still exists!!

Any Idea?

Thanks

You should show your real code - posting pseudocode won't help us solve the issue.

Sorry, Here is the code:

public override Install(IDictionary stateSaver)
{
  String path = this.Context.Parameters["targ"].ToString();
  DirectoryInfo dir = new DirectoryInfo(path);
  foreach (FileInfo f in dir.GetFiles())
  {
    if (f.Name == "MyFile.txt")
      File.Delete(f.FullName);
  }

  base.Install(stateSaver);
}

Something like this:

public static string ConvertTimeString(string time)
{
    return DateTime.ParseExact(
        time,
        "h.mmtt",
        CultureInfo.InvariantCulture).ToString("HHmm");
}

What? That's not right.

Are you talking about user input? Why not have the user enter the data in the format you require?

WebBrowser control and Ajax requests

Hello everyone!

I'm using a WebBrowser control in my app to load a page that updates its content dynamically via Ajax. I need to access the updated content to do some processing, but since the calls are made with Ajax the page doesn't get refreshed and thus the DocumentComplete event doesn't fire.
Is there a way to get notified when a call is made using the XMLHttpRequest object? Some event fires maybe?
Any help will be appreciated,
TIA

Javascript calling a c# method

11-Aug-09 3:41

Hi everyone,

I have a form on my website and I'm thinking about creating a little javascript function to perform validation. I know asp.net has validation built in, but there are some other things I'd like the function to do that can't be done with the asp.net validation plus it's a learning project. I have a button at the end of the form which I would like to call this javascript function which will validate the form input fields, but then after that I'd like it to call the c# code behind which will access the database and do some other server side functions. Is there a way this can be done? Can you attach two "onClick" event handlers to a single button, or do I have to do something with a "hidden button" that is linked to the codebehind and have the javascript "click" it when it's done?

Thanks!

What you're talking about doing is having the Javascript force a server side post back event. You might want to start looking at websites such as this[^].

Ah, that's the ticket! I had a general idea of what I needed the browser to do, but just wasn't sure what it was called. Then I tried googling for "javascript to click a hidden button" or "attaching multiple events to a button" but wasn't getting anywhere. Thank's again for the help!
