Capturing the free text into the ComboBox

[Ron Boehm]

I want to type some data into the ComboBox Text area and hit enter to have that data added to the combobox.

How can I do that?

Hello Ron,


Here s my complete code for achieving same functionality. I hope the code will work for you.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" MarkFirstMatch="false" runat="server" AllowCustomText="True"
    AutoPostBack="True" OnClientKeyPressing="OnClientKeyPressing">
    <Items>
        <telerik:RadComboBoxItem Text="RadComboBoxItem1" />
        <telerik:RadComboBoxItem Text="RadComboBoxItem2" />
    </Items>
</telerik:RadComboBox>

CS:

protected void Page_Load(object sender, EventArgs e)
{
    if (RadComboBox1.Text != "")
    {
        if (RadComboBox1.Items.FindItemByText(RadComboBox1.Text) == null)
        {
            RadComboBoxItem newItem = new RadComboBoxItem();
            newItem.Text = RadComboBox1.Text;
            RadComboBox1.Items.Add(newItem);
        }
    }
}

JavaScript:

<script type="text/javascript">
    function OnClientKeyPressing(Sender, args) {
        if (args.get_domEvent().keyCode == 13) {
            __doPostBack('RadComboBox1.ClientID', '');
        }
    }
</script>

Good luck,
Shinu.
