update datatable in gridview

Question

Hi,

I have form1 and form2.

Form 1 with gridview shows the data from the database. (I wrote this logic in form1 load event).

form2 is for updating the data. when the data entered in form2 and clicks button it updates the data in the database.

No my problem is: I want to see the updated data in the form1 datagridview automatically.

i tried with form2 closing  event  with form1.refresh();

it is not working.

Thanks,

Darma

 

Answer 1

try this:

  private ArrayList Keys = new ArrayList();
  private void InvWiz0_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
  {
     Keys.Add(e);
  }


this "i think" will capture each key you press on the keyboard and add it to an arraylist. As I have added the whole KeyEventArgs object, you will be able to go through and view each one and it's properties.

You have to cast it back to an KeyEventArgs when reading tho.

ie.

object[] Keys_Ar = Keys.ToArray();
foreach(KeyEventArgs Key in Keys_Ar)
{
}

or

object[] Keys_Ar = Keys.ToArray();
for(int i = 0; i < Keys_Ar.Length; i++)
{
   ((KeyEventArgs)Keys_Ar[i]).property
}

P.S I hope you are not looking to use this as a keylogger.!

Override Your control - OnKey...() or ProcessKey...() protected methods.
In OnKey... KeyEventArgs see Handled property.
Remember method arguments in Your own buffer to future use - string isn't good to remember all keyboard input (shift, control, alt modifiers etc)
