javascript change asp:textbox value to invoke subroutine

[snobrdinrtiste]

hi everyone,
I was trying to use Javascript to change an asp:textbox's value and once that value changes I want the textbox__TextChanged SubRoutine to fire...
but the problem is, is that javascript will chance the textbox's value but the SubRouting will not fire unless i manually change the value in the asp:textbox...

does anyone know of a way to get the subroutine to fire?

try calling the onchange event directly using JS:

document.getElementById("txtBoxId").onchange();

Known is handfull, Unknown is worldfull

 

[snobrdinrtiste]

but will that call the vb subroutine in the code behind page?

 

[vbkris]

yes it will. try it...

Known is handfull, Unknown is worldfull

 

[vbkris]

did it work???

Known is handfull, Unknown is worldfull

 

[snobrdinrtiste]

no i'm not sure how to do it...
can you give me a quick example?

i'm doing this:

document.getElementById("txtBoxId").onchange = function() {
//not sure what to put here to call the subroutine ???
}

 

[vbkris]

document.getElementById("txtBoxId").onchange()

thats all, no function there, just that single line...

vbkris,
what if i want to use an asp:textbox to handle the value change?

because i want to use that textbox's value in the subroutine...

is that possible?

 

[vbkris]

yes u can, normally this onchange event is fired when u change the control's value normally. in JS u r just forcing the sme automatically, so it should work as if theere was a manual change...

[snobrdinrtiste]

just that line doesn't work.... ie and firefox says there is an error with that statement...

 

[vbkris]

k, will try it out and give u a sample...
