Hi Iin, welcome to daniweb. :)
First of all, I'm not an expert. An expert is someone who has made all the possible mistakes. I'm not even halfway...

In your code, you don't seem to loop through your selected cells. Here is an example on how to do that.
Hope it helps.

thanks for the reply sir,
but I was so caught up in this situation, is there any example more relevant to the situation that I experienced ??
on link that you gave, I am so confused where to start? Can you teach me a little bit sir?

when i select like this :
gbr1.png

there is no problem,

but when i select row like this:
gbr2.png

it cannot sent to crystalreport

Don't know much about cristal reports.
But what I was trying to say was:
You got to have some kind of loop:

foreach ( DataGridViewRow R in myDGV.SelectedRows)
{
//do something
}

//or
for (int i =0; i < myDGV.SelectedRows.Count; i++)
{
//do something
}

tq sir, you are my hero.... you open my mind sir... tq tq tq very much...
problem is resolve now
