[CLOSED] bug in combobox valuefield ExtNet 2.1

[mirwais]

Hi all

I think there is a bug in 2.x in combobox, could you confirm: setting valuefield to some Id field so that later one can use it as in combobox.Value does not work. In fact COmbobox.value returns same value as COmbobx.text, that was not like this in 1.x. So is it a bug? or is there anotherway to get Comboboxes value, hier is the example, (see line 68 and 69 when debugging for me combo.value should return always the 'abbr' of Model an not the 'state'):

Hi @mirwais,

Thank you for the report. Fixed in SVN. But used RawText property instead of Text.

You also can use SelectedItems and SelectedItem properties.

Hi Daniil
Thanx for the quickfix, but now the .Text property hast the same value of .Value, which should not happen. Contrary to that as you said cmbo1.SelectedItem.Text and cmbo1.SelectedItem.Value are working fine, so for

 new object[] { "AK", "Alaska", "The Land of the Midnight Sun", 5.99},
//we have:

  var val = cmbo1.Value; //AK
  var txt = cmbo1.Text; //AK but this should be Alaska

 txt =cmbo1.SelectedItem.Text // Alaska
 val = cmbo1.SelectedItem.Value // AK

for now I replaced it using .SelectedItem. all the places and this works. However if these .Value and .Text of Combobox are supposed to return Value and Text respectively, then a fix would be nice. thanks:)

As Daniil mentioned, you have to use RawText instead Text
Text is TextField property which is just call to ToString for Value (string representation of Value)
TextField uses RawText as value but combo uses value from record as own value

So, use RawText to read text property of selected record or use SelectedItems/SelectedItem
