[Solved] Autocomplete hightlights item in dropdown but doesn't actually select it

I have a combobox on a form that is loaded server side. When I type the name of a person in the combobox, it highlights the name in the dropdown and also completes the name in the text area. But, when I hit the enter key it isn't selecting the item. I have an OnClientKeyPressing event set to handle the keystrokes and check for the enter key. But, the get_value() is blank. But, If I actually click on the item in the dropdown, then the get_value() returns a value.

If the items is found in the dropdown, and is highlighted in the dropdown list and autocompletes the text field, why isn't it selecting that item and allowing me to get the value for it with the get_value() method?

<telerik:RadComboBox ID="CustomerSearch" runat="server" Width="180" Height="160"

MarkFirstMatch="true" AllowCustomText="true" CssClass="CustomerSearch" AutoPostBack="true"

EnableVirtualScrolling="true" ShowMoreResultsBox="true" OnTextChanged="CustomerSearch_TextChanged"

OnSelectedIndexChanged="CustomerSearch_SelectedIndexChanged" OnClientKeyPressing="HandleKeyPress"

EmptyMessage="Enter last, first to search..." BackColor="White" Skin="Forest" />

<script type="text/javascript">

function HandleKeyPress(sender, args) {

if (args.get_domEvent().keyCode == 13) {

//this alert message is not null. it is an empty string.

alert(sender.get_value());

}

</script>

How do you reference controls on item client-side?

In my RadTreeList I have two data columns displayed. The first column is a number and the second column is a percent. On the client side I wish to update the percent value when the number changes; and when the percent changes I wish to update the number. Both columns are defined as TreeListNumericColumns and are configured to use a RadNumericTextBox. I have attached OnValueChanged events to both columns.

Using JavaScript if the number changes I can determine the new number, but I do not know how to get a reference to the percent column so I can update the percent. I know how to get a reference to the item containing the numeric column updated and I can get a reference to the table cell containing the percent RadNumericTextBox but I need a reference to the RadNumericTextBox which is in the innerHTML so that I can update the Percent..

Here is my Javascript code for the OnValueChangedEvent when the number changes. This all works but I cannot figure out how to get a reference to the RadNumericTextBox containing the percent so I can update the value displayed on the client.

function NumberValueChanged(sender, eventArgs) {

var treelist = $find('<%=rtvProducts.ClientID %>');

var numericTextBox = sender.get_element();

var item = treelist.getContainerItem(numericTextBox);

var index = item.get_displayIndex();

var column = treelist.getColumnByUniqueName('Percent');

var colname = column.get_uniqueName();

var cell = treelist.getCellByColumnUniqueName(item, colname);

alert(cell.innerHTML);

return;

}

I am using Telerik version 2013.1.417.40

Any help would be appreciated.

Thanks,
Chris J.

Keyboard activation (enter/spacebar) breaks RadButton OnClientClicking handler

In Q3 2013 SP1, the OnClientClicking handler of the RadButton will not get called after using the keyboard (enter key or spacebar) to activate the RadButton.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function clickHandler(sender, args)

{

args.set_cancel(true);

}

</script>

</telerik:RadScriptBlock>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<div>

<telerik:RadButton ID="btnTest" runat="server" Text="Test Me" OnClientClicking="clickHandler"></telerik:RadButton>

</div>

</form>

</body>

</html>

The issue seems to have something to do with the set_cancel() call; if the button is changed to "AutoPostBack=false" and the set_cancel() call is removed, the behavior returns to (mostly) normal. In that case, things work as expected when the enter key activates the button, but the spacebar still causes erratic behavior.

Is there a different way to preserve OnClientClicking behavior with keyboard activation of RadButtons or is this a bug?
