enter key on textbox to run button click event????

hi people,

i am completely stuck trying to get the enter key to submit a search query after typing in a textbox. please help!!!

it sounds such a simple and obvious thing to do, its in software everywhere but for the life of me i can't find a simple answer for a newbie like myself to absorb. here's the scenario in pseudo code...

private sub searchBtn_click...

here's my working search code - reading contents from textbox1,

activates when the button is clicked

end sub

private sub textbox...

i want to know the code required for an enter keypress here, with the cursor still in this field, to submit any text in the text box to the search query i have written in the searchBtn_click event !!!

end sub

i may be thinking this completely wrong, so someone please steer me in the right direction. a knowledgable vb6 colleague of mine did this with very little code but the method he used does not work in vb.net.

cheers me hearties

Sorry to interupt but..

What if you have many buttons binded to a specific point in the database and you want to update the database from the page. the desired reaction is to enter the number and it updates the database and this is set up to be for all fifty boxes.

On the page are many textboxes then:

I enter say 10 into the textbox and it displays the number and updates the database but the key here is to be able to save all the information on the enter command.

[is there something to do with upon page change or a more efficient way]

Use the KeyDown event of your TextBox:

Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown

If e.KeyCode = Keys.Enter Then

'do something here...

End If

End Sub

ok, i'm off to google calling subroutines up, but if it doesn't take much explaining i wouldn't mind a quick demonstration.

cheers you've been a great help (will look up the keypress_up thing too)

wicked that worked, though just did a quick test with a messagebox.

so, am i wrong to think that this keypress down could in effect call the routine i already have once, within my original buttonclick event how would i do that

i'm sure i shouldn't have to paste the search routine code into two different subs would the ideal situation be to have my search in its own subroutine, and then have the keydown and buttonclick events call upon it

forgive me i am a newbie and i think i'm about to be introduced to setting up calling subroutines

many thanks

Yes, you should be able to put your search routine in a separate sub & call that from both events...

I think its standard to put the code in the key_up event instead, something to do with the order the events fire... you might get a keypress or key_up event firing on the control that get the focus after the textbox. Just a thought.

Add the following line of code to your Page_Load event

Page.RegisterHiddenField("__EVENTTARGET", "YourButtonName")
