AutoComplete is not working

[Ramesh]

Hi Experts,

I have tried your AutoCompleteBox with the following code, but it is not working. I could not get any suggesstions and the dropdown list is not showing any suggesstion list. Simply the control works like a TextBox only. Please help me, what is my wrong.

<Window x:Class="Interactivity_Behavior_Demo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:Interactivity_Behavior_Demo.Behavior"
        Title="Test Demo"
        Width="525"
        Height="350">


        <Telerik:RadAutoCompleteBox Name="autocomp" Loaded="autocomp_Loaded_1" Height="30" Width="120"/>

</Window>

public MainWindow()
        {
            InitializeComponent();
            _Source = new ObservableCollection<string>() { "hello", "abc", "123" };
            autocomp.ItemsSource = Source;
        }

private void autocomp_Loaded_1(object sender, RoutedEventArgs e)
        {
            autocomp.IsDropDownOpen = true;
            autocomp.AutoCompleteMode = Telerik.Windows.Controls.Primitives.AutoCompleteMode.Suggest;
            autocomp.TextSearchMode = Telerik.Windows.Controls.TextSearchMode.StartsWith;
        }

Hi Ramesh,

I tried your code with a few modifications and its working fine at my end. You have given a wrong variable name while setting the ItemsSource and you have initialized the ObservableCollection without specifying the type. Please have a look into the following code.

XAML:

<telerik:RadAutoCompleteBox HorizontalAlignment="Left" Margin="34,64,0,0" Name="autocomp" VerticalAlignment="Top" Width="224" Loaded="radAutoCompleteBox1_Loaded" />

C#:

public MainWindow()
{
    InitializeComponent();
    ObservableCollection<string> _Source = new ObservableCollection<string>() { "hello", "abc", "123" };
    autocomp.ItemsSource = _Source;
}

private void radAutoCompleteBox1_Loaded(object sender, RoutedEventArgs e)
{
    autocomp.IsDropDownOpen = true;
    autocomp.AutoCompleteMode = Telerik.Windows.Controls.Primitives.AutoCompleteMode.Suggest;
    autocomp.TextSearchMode = Telerik.Windows.Controls.TextSearchMode.StartsWith;
}

Thanks,
Princy.

Princy,
Thanks for your response.

This is working fine when i have the control seperately.

But i am using this inside RadGrid cell, when i have this inside the with CellEditTemplate and clicking the cell throws null exception.
Also i dont know what i have to add in "CellTemplate", please help me by providing code for both "CellTemplate" and "CellEditTemplate" with AutoCompleteBox.

Thanks,
Ramesh

Hi Ramesh,

We created and attached a sample project for you that shows how to create a CellEditTemplate and CellTemplate with RadAutoCompleteBox in RadGridView.

Hope this is helpful.
