[Gtk-sharp-list] Set item in ComboBox (novice in GTK#)

[Ricard Rosson Llobet]

Hi. When I have to set an item in a Combo box I do the following:

First I have to know which TreeIter is containing the value I want to set. 
If I don't know that TreeIter, then I have to search it by hand doing the 
following:

TreeIter ti;
comboBoxStore.GetIterFirst(out ti)
do
{
if ((int)comboBoxStore.GetValue(ti,1)==2 /*The value I look for*/ )
 break;

}while (comboBoxStore.IterNext(ref ti))

//This loop doesn't check if a value has been found so I will check if the 
last TreeIter has the value I look for
if ((int)comboBoxStore.GetValue(ti,1)!=2 /*The value I look for*/ )
{
 //Haven't found the value in the TreeStore
}

once I know The TreeIter I set it as the active TreeIter in the ComboBox:

cbFiltro.SetActiveIter(ti);

if I don't want to search the TreeIter I have to know it beforehand saving 
it somewhere:

TreeIter[] ti=new TreeIter[3];
ti[0]=comboBoxStore.AppendValues("Option #1", "1");
ti[1]=comboBoxStore.AppendValues("Option #2", "2");
ti[2]=comboBoxStore.AppendValues("Option #3", "3");

(...)

cbFiltro.SetActiveIter(ti[1]);


I suppose this should work for you too.
