Get dynamic text box values

Sheraz Khan · August 24th, 2009, 07:43 PM

Hi,
I got some check boxes appears on a form. The number of check boxes vary from user to user.
Now i want to get the values of all the check boxes that appear on the page once user click the submit button, but the problem is How to get the values of those dynamic check box on the landing page as their name generates dynamically (ck_01, ck_02...)

I tried to use Request.form.count but it returns all the elements... so is there any way to filter it?

Cheers
S

Hi..

Did you try with find control?? even not knowing the exact control name, since they are dynamic you create them so you know how to look for them.

First are you posting to another page? or are you posting to the same page?
Also you probably want to set the viewstate to true if on the same page.

How are you creating the names? are they like you said ck_01, ck_02, etc...

Instead of just creating to checkboxes on the page I would use a container for them that only houses the dynamic checkboxes, that way you don't need to filter if they are the ones you dymanically created...

Either way you can do it with a loop.

With out using a container:

Code:

For Each con As Control In Page.Controls
  If TypeOf con Is CheckBox Then
     If CType(con, CheckBox).ID.StartsWith("ck_") Then
        If CType(con, CheckBox).Checked = True Then
            'Do what you need to do with the value - CType(con, CheckBox).Value
        End If
     End If
  End If
Next

The above code could be simplified but I did that so you could easily follow what was being done.

Now if you add a panel or something to your page and just create your checkboxes there then you don't need to loop all the controls of the page or validate that they are the dynamic ones because you already know they are...

With Container:

Code:

For Each con As Control In CheckBoxPanel.Controls
   If TypeOf con Is CheckBox Then
     If CType(con, CheckBox).Checked = True Then
         'Do what you need to do with the value - CType(con, CheckBox).Value
     End If
   End If
Next

Hopefully I understand you correctly and this at least points you in the correct direction....
