Hi Anthony,
Does the solution in my prior post meet your requirements?
It's possible to actually get the selected value by group name. But we need
to set the value attribution for every RadioButton. For example:
RadioFrom.Attributes .Add("value",RadioFrom.Text); Then, we add these radio
buttons to the table using the method in your first post.
Then, we can get the selected radio value using Request.Form["groupname
"].ToString () in code behind.
If we want to loop through each of the radio control in the User Control or
the page to check which radio button was checked using client side script,
we can do that like this:
1. Set the id for each radio control, something like: radio1,
radio2,¡¡
2. Set the same "groupname" for each radio control.
3. The client side script may like this:
<script language="javascript">
function checkradios(){
for(i=1;i<n;i++)
if(document.all("radio"+i).checked)
alert(document.all("radio"+i).value);
}
</script>
Does this answer your question? Please let me know if you need more
information.
Best regards,
Lewis

| Lewis,
|
| Sorry for the long answer, but basically, I thought it best to explain
| exactly what I'm doing here.
|
| I have created a user control which contains a calendar control and this
| free busy list which I'm creating. The date, as selected by the calendar
| control sets a DateTime variable on the page to the current date. The
| Free/Busy list then displays times from midnight on that day to midnight
the
| following day - a 24-hour block of 6-minute intervals.
|
| Ideally, I'd like to generate a table with 4 cells, like so:
|
| [Time] [Fr] [To] [Free/Busy]
| 00:00 () ()
| 00:06 () ()
| 00:12 () ()
| ..... () ()
| 23:48 () ()
| 23:54 () ()
| 00:00 () ()
|
| Cell [Time] would contain the time, cells [Fr(om)] and [To] would contain
a
| RadioButton control, the value of which would be the Date and Time passed,
| so that the end-user can select a "From" time and a "To" time. Cell
| [Free/Busy] just contains information which is returned by a stored
| procedure, which is the source for the information.
|
| So, my questions are:
|
| 1.
| Since I have set all of the radiobutton controls to have the same
GroupName
| (either "TimeFrom" or "TimeTo") is it possible to find out the control
name
| of the radiobutton checked in each group - a function that you could pass
| the GroupName to which would return either the name of the checked
| radiobutton control (great) or the value of the checked radiobutton
control
| (even better).
|
| Even if a function has to be written (I'm thinking something along the
lines
| of CheckedRadioButton(ByVal GroupName As String) As RadioButton) it's got
to
| be better than the current state of affairs
) Any help you can offer in
| terms of writing such a function would be greatly appreciated - I presume
it
| would have something to do with looping through each of the controls in
the
| User Control or the page with the GroupName as given, and then checking to
| see if ThatRadioButton.Checked is True...
|
| (PS - something like that should be added to the next point release, or
| definately ASP.NET v2.0)
|
| 2.
| Failing that, is there a way of creating a radiobutton list, and then
taking
| the rows that are generated by said radiobutton list, and adding them to a
| table that already exists - either a System.Web.UI.WebControls.Table or a
| System.Web.UI.HtmlControls.HtmlTable - and still be able to query the
| RadioButtonList.SelectedValue value?
|
| 3.
| Failing both of the above, what would you suggest?
)
|
|
| Cheers Lewis,
| Anth
