ASP.NET3.5 Webforms. Am trying to put a validator on the drop down list, only if the checkbox is checked.
This doesn't work. If I put an alert in the onclick event, it does show.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
how to checked all children if parent where checked in tree view form i had reseach for some coding but it had a error which is "Type 'MSComctlLib.Node' is not defined." do i need to add any reference of it?
Apparently the checked="False" attribute confuses the browser and I end up with a checked checkbox. On PostBack when I test the value of the checkbox, it's False (unless I change it) so it's got to be a browser presentation issue. I know that when you write a checkbox in straight HTML, the checked attribute doesn't require a value, i.e.:
I've got four radio buttons for a poll and only want a single one to be checked (at most) at any given time so checking another should disable the other 3. I've tried
Protected Sub RadioButton4_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButton4.CheckedChanged If RadioButton4.Checked = True Then RadioButton1.Checked = False RadioButton2.Checked = False RadioButton3.Checked = False End If
If i have 3 asp.net checkboxes in my asp.net webform namely : CheckBox1, Checkbox2, Checkbox3 and a textbox namely textbox1
If Checkbox1.text ="1" Checkbox2.text ="2" Checkbox3.text ="3"
I WANT :
if checkbox1 is already checked ... if checkbox is remain checked and even after i check checkbox2 and checkbox3 then the output in textbox would be 2,3 ..... by ignoring already checked checkbox text ...
LOGIC I WANT : Ignore already check checkboxes and insert recent checkbox text to textbox1 as comma seperated string ...
