Hi there,

I am sure it is something very trivial, but I've spent couple of hours on that already and I think I am missing some obvious thing at that point.

I am trying to have something similar to next demo: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

However, filtering just doesn't work at all. Typing in the ComboBox is not doing anything.

Here is my sample application:

<telerik:RadScriptManager ID="m1" runat="server"/>

<telerik:RadComboBox ID="b1" runat="server" AutoPostBack="true"

AllowCustomText="true" Filter="Contains"

Style="vertical-align: middle;" Width="100px" Label="Filter:">

<Items>

<telerik:RadComboBoxItem Text="None" Value="0" />

<telerik:RadComboBoxItem Text="Contains" Value="1"/>

<telerik:RadComboBoxItem Text="StartsWith" Value="2" />

</Items>

</telerik:RadComboBox>

As you can see example is very simple and there is literally nothing in there.

I also tried setting

DataTextField to Text or Value. Doesn't matter - still no results.

I also tried to do DataBind() from server side code to ObservableCollection<string> and Dictionary<string,string> with no results as well.



Please advise.



Thanks,

Nick

Shinu,

I don't have 2nd ComboBox in my project. Example I showed is all I have in my sample project. I just happened to copy values from the demo site. Just so no one get confused about sample values here is updated still not working sample project:

<telerik:RadScriptManager ID="m1" runat="server"/>

<telerik:RadComboBox ID="b1" runat="server" AutoPostBack="true"

AllowCustomText="true" Filter="Contains" Width="100px">

<Items>

<telerik:RadComboBoxItem Text="Test1"/>

<telerik:RadComboBoxItem Text="Blah"/>

<telerik:RadComboBoxItem Text="Foo"/>

</Items>

</telerik:RadComboBox>

That is all I have in the project, I have only omitted <html>,<head>, and <body> tags.

I also tried setting filter for my comboBox on Page_Load but that didn't help either.

Thanks,
Nick

Hello Nick,
I cannot find any issue with your code and the same code worked as expected at my end.
Here I am pasting my entire code and and please try it in an independent page.
aspx:

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

<head runat="server">

<title></title>

</head>

<body>

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

<div>

<telerik:RadScriptManager ID="m1" runat="server"/>

<telerik:RadComboBox ID="b1" runat="server" AutoPostBack="true" AllowCustomText="true"

Filter="Contains" Width="100px">

<Items>

<telerik:RadComboBoxItem Text="Text1" />

<telerik:RadComboBoxItem Text="Text2" />

<telerik:RadComboBoxItem Text="Text3" />

</Items>

</telerik:RadComboBox>

</div>

</form>

</body>

</html>

Thanks,
Shinu.
