How I can from client javascript know when one of my
textboxes, Radio Button List, drop down box, etc...
Validated to False when submitting the form.

I can get the page_Isvalid==false but i need to know which
control is empty or not selected, so i can put the
cursor...

//Sample code
if (page_Isvalid==false){
if (txt_box1.value.length<1){
document.GetElementById('txt_box1').Focus()
}
}

The code above works great but I don't now how to approach
when i have a dropdownbox, radioButton list, etc...


Thanks,
dmedina
 
The way I do the DropDownList boxes is I have the selected item say
something like "make a selection" and it has a value of 0 (none of my other
values have a 0 value.) that value is hardcoded as part of the list. Yes I
did have to override the asp DropDownListBox to have this functionality, but
you could also do it by hand.

Then I step through it the same way you did with the TextBox except for the
list box.

if ( ddl_box1.value == "0" )
document.GetElementById( 'ddl_box1').focus()

HTH,
