RadComboBox ItemChecked validator conflict

Hello,
I have a problem using RadComboBox with the ItemChecked event when a validator is present on the page. ComboBox has the CausesValidation property set to false. Checkboxes work correctly, however clicking on the item label does not check the item and after a while results in timeout error:
Error: Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.

Following is the demo page:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager ID="rsmMain" runat="server" EnablePageMethods="true" EnableScriptGlobalization="true" EnablePartialRendering="true" />
<div>

<asp:TextBox runat="server" ID="tbInput" /><asp:RequiredFieldValidator ID="rfvInput" runat="server" ControlToValidate="tbInput" ErrorMessage="Error" />
<asp:UpdatePanel ID="upActivitySelector" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
<ContentTemplate>
<telerik:RadComboBox runat="server" ID="cbTest" AutoPostBack="true" CausesValidation="false" CheckBoxes="true">
<Items>
<telerik:RadComboBoxItem Text="test1" />
<telerik:RadComboBoxItem Text="test2" />
</Items>
</telerik:RadComboBox>
</ContentTemplate>
</asp:UpdatePanel>

</div>
</form>
</body>
</html>

public partial class RadComboBoxTest : System.Web.UI.Page {
protected void Page_Init(object sender, EventArgs e) {
cbTest.ItemChecked += new RadComboBoxItemEventHandler(selector_ItemChecked);
}

protected void selector_ItemChecked(object sender, RadComboBoxItemEventArgs e) { }

}

How to set Header Template Text when using Items_Requested

I'm using the below markup to create a Combox that has a Header Template. I have a potential 10000+ records so I'm using LoadOnDemand to populate the rows BUT I would like to be able to populate the HEADER labels immediately. See the second code snippet..

The code to fire the GetTranslation is currently ignored but I've also tried the below in Init, PreRender, ItemsCreated, in all cases its either too early or in ItemsCreated, it only fires once I actually start type, which is too late.

Dim HeaderCommitmentNumber As Label = DirectCast(e.Item.FindControl("lblCommitmentNumber"), Label)

Dim HeaderVendor As Label = DirectCast(e.Item.FindControl("lblVendor"), Label)

HeaderCommitmentNumber.Text = MasterPage.GetTranslation("Number", False)

HeaderVendor.Text = MasterPage.GetTranslation("VendorDescription", False)

<telerik:RadComboBox ID="CommitmentNumber" runat="server" Width="100px" Height="200" DropDownWidth="450"

EnableLoadOnDemand="true" ItemsPerRequest="10" DataTextField="ReferenceDocumentNumber" HighlightTemplatedItems="true"

ExpandDelay="0" ExpandAnimation-Duration="0" CollapseAnimation-Duration="0" CollapseDelay="0" LoadingMessage='<%#MasterPage.GetTranslation("Loading", False)%>' >

<HeaderTemplate>

<div style="width: 420px;">

<div style="width: 75px; float: left; padding: 0 11px 0 11px; color: rgb(0, 21, 110) !important;">

<asp:Label ID="lblCommitmentNumber" runat="server" Text='<%#MasterPage.GetTranslation("Number", False)%>' Font-Bold="true" />

</div>

<div style="width: 295px; float: left; padding: 0 11px 0 11px; color: rgb(0, 21, 110) !important;">

<asp:Label ID="lblVendor" runat="server" Text='<%#MasterPage.GetTranslation("VendorDescription", False)%>' Font-Bold="true" />

</div>

</HeaderTemplate>

<ItemTemplate>

<ul>

<li>

<ul>

<li id="col1">

<div style="width: 75px; float: left; padding: 0 11px 0 11px; color: rgb(0, 21, 110) !important;">

<asp:Label ID="ReferenceDocumentNumber" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "ReferenceDocumentNumber").ToString()%>'></asp:Label>

</div>

</li>

<li id="col2">

<div style="width: 295px; float: left; color: rgb(0, 21, 110) !important; margin-left: 5px;">

<div>

<asp:Label ID="lblVendor" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Vendor").ToString()%>'></asp:Label>

</div>

<div>

Losting selecteditem in listview

hi,

here is my listview

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
<telerik:RadTextBox ID="txtDSTableLike" runat="server" EmptyMessage="Table Like" OnTextChanged="txtDSTableLike_TextChanged"></telerik:RadTextBox>
</div>
<div class="table-selection-list">
<div id="content_1_1" class="contents_1">
<telerik:RadListView ID="lvDSTableSelection" runat="server" AllowMultiItemSelection="true" OnSelectedIndexChanged="lvDSTableSelection_SelectedIndexChanged" autopostback="false">

<ItemTemplate>
<asp:LinkButton ID="LinkButton1" CssClass="selectedButtons" runat="server" CommandName="Select" Font-Underline="false">
<p ><%# Container.DataItem %></p></asp:LinkButton>
</ItemTemplate>
<SelectedItemTemplate >
<p ><%# Container.DataItem %></p>
</SelectedItemTemplate>
</telerik:RadListView>
</telerik:RadAjaxPanel>

First of all Icall this function and SelectedItems returns selected data perfectly

protected void lvDSTableSelection_SelectedIndexChanged(object sender, EventArgs e)
{
..

orcl.Owner = ddDSSchema.SelectedText;
orcl.TableName = lvDSTableSelection.SelectedItems[0].DataItem.ToString(); --> returns selected data perfectly
var result = client.GetColumnNames(orcl);

lbDSNominal.DataSource = result.Data;
lbDSNominal.DataBind();
}

after I call above function, I call this function but now SelectedItems return null

protected void btnNext_Click(object sender, EventArgs e)
{

developmentSample.TableName = lvDSTableSelection.SelectedItems[0].DataItem.ToString(); --> return null at selected item
}

how can I fix it? Why am I losting selecteditem ?

Filter on Radgrid

I have a RadGrid with several columns. Some of them have comboboxes and some of them have textboxes as filter input. If I first filter using one item from Combobox, such as state "Florida" and then I try to filter again using the textbox and input a searchable word it works fine and bring me the result. However if the word is not searchable I get the error below.

MarkFirstMatch telerik radcombobox filter one character ONLY in IE 11

Hello,

I've a serious problem with RadComboBox

When Filtering RadComboBox IE 9 , it works fine actually with markfirstmatch property and i could filter with more than one character
For example if i am filtering Combobox to find item with name "AmrRafat", i could write 'amr' and the combobox will do the rest and finds this item.

but when trying the same scenario in IE 11, it only accepts the first character and each time i am pressing a key it consider it as the first character for filtering
For example if i am filtering Combobox to find item with name "AmrRafat", and i tried to write 'amr' Then Combobox will assume only one character and filter with it

.aspx File

<telerik:RadComboBox ID="cmbPayers" runat="server" Width="100%" AutoPostBack="true" Filter="Contains" MarkFirstMatch="true" TabIndex="11" OnSelectedIndexChanged="cmbPayers_SelectedIndexChanged"></telerik:RadComboBox>

Any Ideas?

Please let me know how to solve this.
