Hello there,
Currently I am working with the project which needs dynamically generated checkboxes and i have generated dynamic checkboxes but i am facing problem with getting the vaue of selected checkboxes.
Problem is described below in detail to easily understood, so please let me know if you come to know...
Example:
I am creating a form to assign rights to site admin for managing different module of the site from back end. Please have a look at attached file to better understand the structure of admin rights form which i used.
I had created checkbox dynamically with below statement FOR EACH Module.
lblCheck.Text += "<input type='checkbox' name='chk[" + daDetail["Module_id"] + i.ToString() + "]' value='A'>Add
lblCheck.Text += "<input type='checkbox' name='chk[" + daDetail["Module_id"] + i.ToString() + "]' value='E'>Edit
lblCheck.Text += "<input type='checkbox' name='chk[" + daDetail["Module_id"] + i.ToString() + "]' value='D'>Delete
lblCheck.Text += "<input type='checkbox' name='chk[" + daDetail["Module_id"] + i.ToString() + "]' value='S'>Search
Say my Module_Id = 12
After form submit I got value with
form.querystring["chk121"]; form.querystring["chk122"];
form.querystring["chk123"];
form.querystring["chk124"];
But I want to use foreach loop for getting the values of each selected checkboxes Because there are more then 50 moudles. so please,let me know how to do this? Main problem is that I don't know how many total checkbox generated dynamically, that is why I have to use foreach or for loop.
Any help, advice or pointers on this matter would be highly appreciated.
Thanks,
Paresh

Hi,
I am writing some sample code that generate dynamic CheckBoxes on PageLoad and dynamically displays which one has been selected.
The idea is, instead of wating for the user to click a button to get the values why dont we try to get the value as soon as its been checked.
Hope it helps....

'Declarations
Dim ckb(7) As CheckBox
Dim i As Integer
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
For i = 0 To 7 Step 1
ckb(i) = New CheckBox
ckb(i).Text = "CheckBox" + i.ToString
ckb(i).AutoPostBack = True
Panel1.Controls.Add(ckb(i))
Next
End Sub
Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.PreRender
For i = 0 To 7 Step 1
If (ckb(i).Checked = True) Then
Response.Output.Write(ckb(i).Text)
End If
Next
End Sub

yes, you are right BUT how to get the value of slelected cehckboxes using foreach()..., You have assumed the static value(7), pls replace 7 with dynamic value
Pls let me know if you are aware of using foreach()..
Waiting for your reply..

your code will be something similar to this:
foreach(control cb in form1.controls)
{
if(typeof(cb)==getType(checkbox))
{
string cbName = cb.Name;
bool cbChecked = cb.checked;
}
}
the code above is like pseudocode, i am a little bit lazy to open visual studio to do coding myself. if you cant do it with this information i can help you better later.
