Hi Jason,
One solution that comes to my mind is to override the method inserting this text in the AutoCompleteBoxViewElement. To do that you need to create a descendant of the control, the RadAutoCompleteBoxElement and the AutoCompleteBoxViewElement. Here is the code for this:
class MyAutoCompleteBox : RadAutoCompleteBox
{
protected override RadTextBoxControlElement CreateTextBoxElement()
{
return new MyRadAutoCompleteBoxElement();
}
public override string ThemeClassName
{
get
{
return typeof(RadAutoCompleteBox).FullName;
}
}
}
class MyRadAutoCompleteBoxElement : RadAutoCompleteBoxElement
{
protected override TextBoxViewElement CreateViewElement()
{
return new MyAutoCompleteBoxViewElement();
}
protected override Type ThemeEffectiveType
{
get
{
return typeof(RadAutoCompleteBoxElement);
}
}
}
class MyAutoCompleteBoxViewElement : AutoCompleteBoxViewElement
{
protected override int InsertTokenizedTextBlocks(int index, string text, bool performInvalidation)
{
if (this.OnTokenValidating(text) == false)
{
return -1;
}
StringBuilder textBuilder = new StringBuilder();
for (int i = 0; i < text.Length; i++)
{
char symbol = text[i];
bool isDelimiter = symbol == this.Delimiter;
if (isDelimiter)
{
if (textBuilder.Length > 0)
{
string blockText = textBuilder.ToString();
bool isValid = true;
if (isValid)
{
ITextBlock textBlock = this.CreateBlock(blockText, TokenizedTextBlockElementType);
textBlock.Index = index;
this.Children.Insert(index, textBlock as RadElement);
}
else
{
textBuilder.Append(symbol);
blockText = textBuilder.ToString();
index = base.InsertTextBlocks(index, blockText, TextBlockElementType);
}
index++;
textBuilder = new StringBuilder();
}
continue;
}
else if (symbol == TextBoxViewElement.LineFeedSymbol ||
symbol == TextBoxViewElement.CarriageReturnSymbol)
{
if (textBuilder.Length >= 0)
{
textBuilder.Append(symbol);
index = base.InsertTextBlocks(index, textBuilder.ToString(), TextBlockElementType) + 1;
textBuilder = new StringBuilder();
continue;
}
}
textBuilder.Append(symbol);
}
if (textBuilder.Length > 0)
{
index = base.InsertTextBlocks(index, textBuilder.ToString(), TextBlockElementType) + 1;
}
return index - 1;
}
}
Let me know how this works for you.
