Binding to code behind from dropdowncontent in dropdownbutton

Question

4.00/5 (1 vote)

See more:

I have created a usercontrol, containing a dropdownbutton.

The dropdownbuttons dropdowncontent contains a number of checkboxes, which are supposed to be bound to boolean properties of the usercontrol itself (for safe keeping until a ok is pressed and the booleans gets copied to the datacontext where it is used as search criteria in a database search).

But {StaticResource Self} does not work and neither does looking for the ancestor type. Propably because the checkboxes are in the dropdowncontent area of the dropdownbutton.

The question is: How do I in XAML bind to properties on my usercontrol (that is, properties defined in the code behind file) from a dropdownbuttons dropdowncontent?

Thanks!

Hi,

I think you must use delegate

Try this example:
In your code behind page:

protected void Page_Load(object sender, EventArgs e)
{
   //Do something?...
  ucOverride.SendValue += delegate(bool checkedOverride)
   {
      if (checkedOverride == true)
      {
          // Do somthing here?...
          //...
      }
   };
   //Do something?...
}

In you custom control page code behind:

C#

public delegate void SendData(bool checkedOverride);
public event SendData SendValue;


protected void btnOk_Click(object sender, EventArgs e)
{
  //UpdatePanel1.Update();
  bool checkeds = false;
  if (chkOverride.Checked)
  {
     checkeds = true;
  }
  else
  {
     checkeds = false;
  }
  if (SendValue != null)
  {
            SendValue(checkeds);
  }
}

Hope this could help...
