Hi,
im trying to extract the value of a radcombobox. Previously this value was stored in a regular asp textbox, then I could do like this to get the last part of the string value in js.
im trying to extract the value of a radcombobox. Previously this value was stored in a regular asp textbox, then I could do like this to get the last part of the string value in js.
Right(document.getElementById('Mybox').value, 5) < 1000
this number is built up like so. 'project-module-1xxx'
I.E I only want to get values that are higher than 1000. How can I get the same functionality from a radcombobox ?
I tried with
Right($find("Mybox").get_text(), 5) < 1000) but that didnt recognize the right functionality.
all help appreciated,

Hello,
When you are trying to access RadControls the correct method is to use $find instead of document.getElementByID as follows.

Hi,
this would then be the solution
var txtID = $find("MyBox");
if (Right(txtID.value, 5) < 1000) {
// do some updates here
}
That does not work im afraid, you get a Error: The value of the property 'Right' is null or undefined, not a Function object

Hi,
thats not really what I asked.
I have no problem getting the value from the radcombobox, I have a problem extracting a part of it to JS.
if it was an asp control. this is what i would do. This will extract the last 5 numbers from the string
Right(document.getElementById('Mybox').value, 5) < 1000
now if mybox was a radcombobox instead, then how would I write that above code ?
