I mean this:
If I create a method X(int value).
I can set
MyActionEvent += X;
And GenericActionEvent += X;

So, why not pass a MyActionInt to an Action<int> ?
You can say the type does not know anything about the parameters, but that's what I consider wrong in delegate design. Not that such opinion will change anything.

Does anyone know of a way to read a IO stream from the .net adobe pdf viewer control.
I am trying to extract entered text from a pdf.
I realize I could do this from a pdf file however I would much prefer to do it from the viewer in memory.

I have a DataGridView that I bind to a DataTable which is obtained by querying my database. The context for this DataGridView can change, and when that happens I re-run the query, and bind a new DataTable to the DataGridView

I also handle the CellFormatting event to highlight certain values.

What I have discovered is that the CellFormating event fires (one time with e.RowIndex == 0 and e.ColumnIndex == 0) when binding to an empty table, but only when the DataGridView was previously bound to a DataTable that has rows.

This seems like a bug to me. Any thoughts?

This is a technical forum, your question is i)too wide ranging, and ii)nothing to do with .NET.

fact (noun)
1. Knowledge or information based on real occurrences: an account based on fact; a blur of fact and fancy.
2.
a. Something demonstrated to exist or known to have existed: Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact.
b. A real occurrence; an event: had to prove the facts of the case.
c. Something believed to be true or real: a document laced with mistaken facts.
3. A thing that has been done, especially a crime: an accessory before the fact.
4. Law The aspect of a case at law comprising events determined by evidence: The jury made a finding of fact.

--------------------------------------------------------------------------------

[Latin factum, deed, from neuter past participle of facere, to do; see dh- in Indo-European roots.]
Usage Note: Fact has a long history of usage in the sense "allegation of fact," as in "This tract was distributed to thousands of American teachers, but the facts and the reasoning are wrong" (Albert Shanker). This practice has led to the introduction of the phrases true facts and real facts, as in The true facts of the case may never be known. These usages may occasion qualms among critics who insist that facts can only be true, but the usages are often useful for emphasis.
