I have the following codes in ascx.
It is two radio buttons in ascx.

on aspx side when I tried to call the ascx, how can I code that so the aspx can see view
radio button is selected?

Thanks,
<tr><td>
    <cc1:OboutRadioButton AutoPostBack="true" FolderStyle="../eServices/UIStyleControls/Obout/Interface/styles/plain/OboutRadioButton" GroupName="MasterPolicyType" Font-Bold="true" Text="Short Term Policy" ID="RdoShortTermPolicy" runat="server">
    </cc1:OboutRadioButton>
     </td>
    <td><br /></td>
    <td>
    <cc1:OboutRadioButton AutoPostBack="true" FolderStyle="../eServices/UIStyleControls/Obout/Interface/styles/plain/OboutRadioButton" GroupName="MasterPolicyType" Font-Bold="true" Text="Annual Policy" ID="RdoAnnualPolicy" runat="server">
    </cc1:OboutRadioButton>
     
    </td>
</tr>

ASCX CodeBehind:

public bool IsRdoShortTermPolicySelected
{
      get
      {
           return RdoShortTermPolicy.Checked;
      }
      set
      {
           RdoShortTermPolicy.Checked = value;
      }
}

public bool IsRdoAnnualPolicySelected
{
      get
      {
           return RdoAnnualPolicy.Checked;
      }
      set
      {
           RdoAnnualPolicy.Checked = value;
      }
}

Open in new window


Then from your ASPX, you can call the control of your ascx and access one of those properties, like this:

if (ascxControl.IsRdoAnnualPolicySelected)
{
     // ... do something
}

Open in new window

The setters on those properties is of course optional, the ASCX codebehind could also look like this if you don't want to be able to programmatically check the radio buttons and only allow the user to do it:

public bool IsRdoShortTermPolicySelected
{
      get
      {
           return RdoShortTermPolicy.Checked;
      }
}

public bool IsRdoAnnualPolicySelected
{
      get
      {
           return RdoAnnualPolicy.Checked;
      }
}

Open in new window


The above only allows those properties to observe whether or not the radio buttons are selected.

With this example, the ASPX page can still do this:

if (ascxControl.IsRdoAnnualPolicySelected)
{
     // ... do something
}

Open in new window


but it can't do this:

ascxControl.IsRdoAnnualPolicySelected = false;

Open in new window


Because there are no publicly accessible setters defined.  With this example if you attempt to set it programmatically you will break the build because the compiler will tell you it is read-only.

Thanks. Any ways to make two in one ? Meaning
When just call one property to determine
Which one is selected on aspx?
It may be possible because there is group name in radio
Button on ascx file....

Yes, it would be a string though stating the ID of the control selected.  Would that work?  The codebehind of the ASCX property would look like this:

public string SelectedRadioButton
{
      get
      {
           if (RdoShortTermPolicy.Checked)
              return RdoShortTermPolicy.ID;
           else if (RdoAnnualPolicy.Checked)
              return RdoAnnualPolicy.ID;
           else
              return string.Empty;
      }
}

Open in new window


If RdoShortTermPolicy were checked, that property would return the value "RdoShortTermPolicy".

Of course, you could make the return string be anything you want, such as:

public string SelectedRadioButton
{
      get
      {
           if (RdoShortTermPolicy.Checked)
              return "short term";
           else if (RdoAnnualPolicy.Checked)
              return "annual";
           else
              return string.Empty;
      }
}

Open in new window


With this example, if RdoShortTermPolicy were checked, the return value of the property would be "short term".

You can also make it an int return value, like a value of 0 if RdoShortTermPolicy is checked, a value of 1 if RdoAnnualPolicy is checked, and a value of -1 if neither are checked, like so:

public int SelectedRadioButton
{
      get
      {
           if (RdoShortTermPolicy.Checked)
              return 0;
           else if (RdoAnnualPolicy.Checked)
              return 1;
           else
              return -1;
      }
}

Open in new window


The sky's the limit ;)
