i have a datagrid and everytime the focus of the cursor on one of the cells and i press enter/return key, i want to emerge a modal form. but it seems that enter key doesn't raise the keydown/keypress/keyup event. the msdn provides information like this:

"Certain keys, such as the TAB, RETURN, ESCAPE, and arrow keys are handled by controls automatically. In order to have these keys raise the KeyDown event, you must override the IsInputKey method in each control on your form. The code for the override of the IsInputKey would need to determine if one of the special keys is pressed and return a value of true"

but it doesnt provide me with the example how to do that. please
anybody can show me how to make use this isinputkey method

thanks in advance,
albert

You can manually capture the Enter key using javascript, and here's an example:

function keyDownHandler(buttonId) {
    // Process only the Enter key
    if (event.keyCode == 13) {
        // cancel the default submit
        event.returnValue = false;
        event.cancel = true;

        if (document.getElementById(buttonId))
            document.getElementById(buttonId).click();
    }
}
