Iterate trough RadRibbonBar

[Michael]

Hi guys,

I'm working on a program where I need to change Text and ToolTips of different RadRibbonBar Elements.
The reason for this is that I need to be able to change the language on the fly.
This came as a request for an already existing program.
As the language will be changed for the whole program and all windows, I wanted to use a public function,
that will be called when I press a button and when a window is loaded / get the focus.
The Language information itself is stored in a database table.

private void radButtonElementEnglish_Click(object sender, EventArgs e)
{
     ChangeLanguage(this, "English")
}

Changing Text  and ToolTips on Textbox, RadTextBox or other controls is no problem. I just can't find a way to iterate though a RadRibbonbar. Same counts for Tooltips on a RadGridView.
I added further table columns that hold names and types of RibbonBarElements as kind of a path to get to an element.
"radRibbonBar.ribbonTab.radRibbonBarGroup", "radRibbonBar<Form.Name>.ribbonTabMain.radRibbonBarGroupSave"
Still din't find a way to diretcly address a RadButtonElement for example.

public void ChangeLanguage(Form frm, String Language = "English")
{
 RadTextBox RadTextBoxTip = null;
 RadDropDownListCustom radDropDownListCustomTip = null;
 RadLabel radLabelTip = null;
 RadButtonElement radButtonElementTip = null;
 RadGridView radGridViewTip = null;
 SqlCommand commandGetData = null;
 try
 {
    commandGetData = SQLQuery();
    commandGetData.CommandText = "SELECT  Element_Name, Element_Typ, Element_Text_EN, ToolTip_Text_EN, Element_Text_DE, ToolTip_Text_DE, From Language WHERE Windowr_Name = @Window_Name";
    commandGetData.Parameters.AddWithValue("@Window_Name", frm.Name.ToString());
    commandGetData.Connection.Open();
    SqlDataReader DataReader = commandGetData.ExecuteReader();
    if (DataReader.HasRows)
    {
         while (DataReader.Read())
    {
     switch (DataReader["Element_Typ"].ToString())
     {
       case ("radTextBox"):
          RadTextBoxTip = (RadTextBox)frm.Controls.Find(DataReader["Element_Name"].ToString(), true)[0];
          if (Language == "English")
          {
        RadTextBoxTip.Text = DataReader["Element_Text_EN"].ToString();
        RadTextBoxTip.TextBoxElement.TextBoxItem.ToolTipText = DataReader["ToolTip_Text_EN"].ToString();
          }
          if (Language == "German")
          {
        RadTextBoxTip.Text = DataReader["Element_Text_DE"].ToString();
        RadTextBoxTip.TextBoxElement.TextBoxItem.ToolTipText = DataReader["ToolTip_Text_DE"].ToString();
          }
          break;
       case ("radLabel"):
            radLabelTip = (RadLabel)frm.Controls.Find(DataReader["Element_Name"].ToString(), true)[0];
        // same as radtextbox
        //radLabelTip.Text
        //radLabelTip.LabelElement.ToolTipText
        break;
       case ("radRibbonbonbar"):
        //..
        RadRibbonBar RadRibbonbarTip = (RadRibbonBar)frm.Controls.Find(DataReader["Element_Name"].ToString(), true)[0];
        //RadRibbonbarTip.Text = ..
        //No Tooltip here
        break;
       case ("ribbonTab"):
        //..
        break;
       case ("radButtonElement"):
            var c = GetAll(frm, typeof(RadRibbonBar));
        MessageBox.Show("Total Controls: " + c.Count());
        break;
       //more case:
       default:
        break;
     }
    }
    DataReader.NextResult();
       }
    commandGetData.Connection.Close();
      }
      catch (System.Data.SqlClient.SqlException ex)
      {
    // showEvents(ex);
      }
      finally
      {
    if (commandGetData != null) { commandGetData.Dispose(); }
      }
   }
 }

public IEnumerable<Control> GetAll(Control control, Type type)
{
   var controls = control.Controls.Cast<Control>();
   return controls.SelectMany(ctrl => GetAll(ctrl, type))
  .Concat(controls)
  .Where(c => c.GetType() == type);
}

There is another thread has some info but I'm still not able to figure out how to solve my problem

And why is there only a RibbonTab and no RadRibbonTab?

I found a way that doesn't make too much work.
A further datafiled which contains the names of the individual elements (Element_Typ_Pfad_Name) helps to
get down to individual elements like that:

case ("radButtonElement"):
try{
    String[] elementPathNames = DataReader["Element_Typ_Pfad_Name"].ToString().Split(new Char[] { '.' });
    RadRibbonBar rbr = (RadRibbonBar)frm.Controls.Find(elementPathNames[0], true)[0];
    RibbonTab rtab = (RibbonTab)rbr.CommandTabs[elementPathNames[1]];
    RadRibbonBarGroup rtgroup = (RadRibbonBarGroup)rtab.Items[elementPathNames[2]];
    RadButtonElement radButtonElementTip = (RadButtonElement)rtgroup.Items[DataReader["Element_Name"].ToString()];
    if (Language == "English")
    {
       radButtonElementTip.Text = DataReader["Element_Text_EN"].ToString();
       radButtonElementTip.ToolTipText = DataReader["ToolTip_Text_EN"].ToString();
    }
    //if (Language == "....


}
catch{}
break;

Saample content of the Element_Typ_Pfad_Name
radRibbonBar1.ribbonTab1.radRibbonBarGroup1

If you know a better way let me know

Hello Michael,

Thank you for writing.

I have prepared a sample project which demonstrates how to iterate over all elements in the RadRibbonBar structure and change their text. 

I hope you will find this useful. If you have further questions, do not hesitate to write back.
