AutoComplete on TextBox?

[Josh Anderson]

As I'm sure you can tell by my recent posts, I've been playing around with the controls for Windows Forms, and I noticed today that the RadTextBox does not include an ability to bind to an autocomplete source like the standard TextBox does.  Is there another way to accomplish this?  One of my RadTextBox controls is for URL entry, and I'd like the option to tie it to the user's history for autocomplete.

Hello Josh Anderson,

Thank you for writing.

The Autocomplete functionality is available witin the RadTextBox. This example shows how to access it, via a simple example. Please refer to the code-segment below:

	TextBox tb = ((TextBox)((RadTextBoxItem)radTextBox1.RootElement.Children[0].Children[0]).HostedControl);
	tb.AutoCompleteCustomSource.AddRange(new string[] {
	"blabla",
	"mlamla",
	"clacla"});
	tb.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.Append;
	tb.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;

Thank you for directing our attention to this functionality. In the upcoming service pack, this functionality will be available at the top-level of the control. There will be no difference in the way you would use a Microsoft TextBox and a Telerik RadTextBox with respect to this functionality.

If you have any additional questions, let us know. We'd love to help you get acquainted with what our product has to offer.

All the best,

Hello, jamsheer,

In order to activate "contains" autocomplete functionality in RadTextBox, you can set the AutoCompleteMode property to AutoCompleteMode.Suggest:

TextBox tb = ((TextBox)((RadTextBoxItem)radTextBox1.TextBoxElement.TextBoxItem).HostedControl);
tb.AutoCompleteCustomSource.AddRange(new string[] {
"blabla",
"mlamla",
"clacla"});
tb.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.Suggest;
tb.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;

In addition, I would like to note that Telerik UI for Winforms suite offers RadTextBoxControl as well that supports auto complete functionality out of the box: https://docs.telerik.com/devtools/winforms/controls/editors/textboxcontrol/autocomplete 

I hope this helps. Let me know if you have further questions.

Hello, jamsheer,

The default values of AutoCompleteMode that RadTextBox and RadTextBoxControl offers are: Append, Suggest, and SuggestAppend. When you choose Suggest option the auto-complete functionality searches for the exact match that starts with the typed character. According to your requirement, you need to search within the whole text for a word that contains a specified character. 

In this case, I would recommend referring to the following KB article that demonstrates how you can create a custom RadTextBoxControl: https://docs.telerik.com/devtools/winforms/knowledge-base/textboxcontrol-autocomplete-contains. I believe this would fit your scenario.

I hope this helps. Should you have further questions please let me know.
