RadMessageBox Details Button

[eusouleon]

In C#, how can I show the Details text of the RadMessageBox control without requiring user to click the Details button (to drop down the details). Thank you.

Hello Rene, 

Thank you for writing.  

Here is a sample code snippet demonstrating how to show the message details immediately after the RadMessageBox is shown: 

private void radButton1_Click(object sender, EventArgs e)
{
    RadMessageBox.Instance.Shown -= Instance_Shown;
    RadMessageBox.Instance.Shown += Instance_Shown;
    RadMessageBox.Show("Message", "Caption", MessageBoxButtons.OKCancel, RadMessageIcon.Info, "Details");
}

private void Instance_Shown(object sender, EventArgs e)
{
    MethodInfo mi = typeof(RadMessageBoxForm).GetMethod("ShowDetails", BindingFlags.NonPublic | BindingFlags.Instance);
    mi.Invoke(RadMessageBox.Instance, null);
}

I hope this information helps. Should you have further questions I would be glad to help.

I have basically done as explained above, but my details pain never opens automatically. 

MethodInfo mi = typeof(RadMessageBoxForm).GetMethod("ShowDetails", BindingFlags.NonPublic | BindingFlags.Instance);

mi is always NULL, so it is not finding the "ShowDetails" method.  Has the method name changed since this was sugguestion was made?

It looks as it has changed, I had to make change to the Event Handler. This is how I got it to work.

      private void HandleRadMessageBoxInstanceShown(object sender, EventArgs e)
      {
         if (sender is RadMessageBoxForm mb)
         {
            if (!string.IsNullOrEmpty(mb.DetailsText))
            {
               mb.ShowDetails();
            }
         }
      }

Hi, Mark,

I am glad that you succeeded to get the message box working in the desired way. Indeed, there was in improvement during the 6 years versions gap and now the ShowDetails method is public.
