I tried to use autocompletebox inside of dataform instead of TextBox. but I cannot see instance name of autocompletebox in the class file.
BTW, If I put autocompletebox outside of dataform, I can see instance name of autocompletebox, "acbEmpName".
So, my question is that Is it impossible to put autocompletebox inside of dataform?
If so, How to use autocompletebox inside of dataform?
I am using silverlight3.
Thanks in advance.
Are you using the template field?
<df:DataFormTemplateField FieldLabelContent="Year">
<df:DataFormTemplateField.DisplayTemplate>
<DataTemplate>
<TextBox Text="{Binding Year}" HorizontalAlignment="Left" />
</DataTemplate>
</df:DataFormTemplateField.DisplayTemplate>
<df:DataFormTemplateField.EditTemplate>
<DataTemplate>
<TextBox Text="{Binding Year}" HorizontalAlignment="Left" />
</DataTemplate>
</df:DataFormTemplateField.EditTemplate>
</df:DataFormTemplateField>
I might be going with the oddest suggestion on this one, but instead of trying to get inside the grid / control tree and be explicit with things, use the Current Column setting.
Ripping off the data template sample in the help files the XAML and basiccode are as follows:
It's not perfect by a long margin in that:
But when it runs, it does respond to a space and move the cursor into the autocomplete box, highlights the text and if I start typing the autocomplete drop down activates. So in principle, setting the current column seems to provide the behaviour you are after.

AutoCompleteBox should work well with DataForm, with the only exception being that AutoCompleteBox does not conform to the "IsReadOnly" convention that some of the other controls do, so in read-only mode your experience visually might be a little less than ideal.
Is it possible that this is a sizing issue? Could you try putting the AutoCompleteBox control inside of a StackPanel, or providing a specific size - height 40 width 120, or something like that, to see if it appears better?
