RadListView Layout Template bug with &lt;ul&gt; &lt;li&gt;
Im binding this

<telerik:RadListView runat="server" ID="rlvMyTaxReportsCustomization"
        onitemdrop="rlvMyTaxReportsCustomization_ItemDrop">
    <ClientSettings AllowItemsDragDrop="true">
        <ClientEvents OnItemDropping="reportDropping" />
    </ClientSettings>
    <LayoutTemplate>
        <ul id="ulMyTaxReportsCustomization" runat="server" class="noBullet">
            <li id="itemPlaceHolder" runat="server"></li>
        </ul>
    </LayoutTemplate>
    <ItemTemplate>
        <li id="liMyTaxReportsCustomization" runat="server">
            <asp:CheckBox ID="MyTaxReportsCustomizationHidden" runat="server" text="Hide" Checked='<%#Eval("hidden").ToString().Equals("1") %>' CssClass="cbHide" />
            <div id="divMyTaxReportsCustomization" class="rlvI" runat="server">
                <div class="rlvDrag" onmousedown="Telerik.Web.UI.RadListView.HandleDrag(event, '<%# Container.OwnerListView.ClientID %>', <%# Container.DisplayIndex%>)">                                              
                    <asp:LinkButton ID="lkbMyTaxReportsCustomization" runat="server" CssClass="aCont">
                        <%#Eval("name") %>
                        <asp:Label ID="lblMyTaxReportsCustomizationFrom" runat="server" Text='<%#Eval("from"," (from {0} )") %>' ></asp:Label>
                    </asp:LinkButton>
                </div>
            </div>
        </li>
    </ItemTemplate>
</telerik:RadListView>

with this CSS

.rlvI
{
    display:block;
}
 
.rlvDrag
{
    display:block;
}
 
.cbHide
{
    float:right;
}
 
.aCont
{
    display:block;
    text-decoration:none;
}
 
.noBullet
{
    list-style-type: none;
    padding: 0;
    margin-left: 0;
}


and Im getting the result in the attached image.

The obvious thing I am looking for is a hide checkbox align to the right and I tried this in a static <ul><li> schema and also in a normal ASP.NET ListView and they displayed as I was lloking for... I know this could be an issue, but could you lend me a hand to make it look as I want to?? it is really important, or maybe if there is a fix for this...

Thanks in advance,

Camilo

Radgrid Filtering onkeypress

Requirements
RadControls version

V.2010.3.1215.35
.NET version

3.5
Visual Studio version

2008 SP1
programming language

VB.Net
browser support

all browsers supported by RadControls


PROJECT DESCRIPTION
[This projects shows major javascript adjustments to a radgrid. It shows how to filter a grid onkeypress so when the user types something into the filter, it will filter by a default filter type that you have set. If they want a specific filter type other than that one, then they must select it using the filter button (the conventional way). It also shows how to avoid javascript errors for columns without filters and for datecolumns so you wont filter an incorrect date.  Hope this is helpful.]

Retrieving DataSource OnPreRender or OnItemDataBound when ObjectDataSource is used
Hello,

My RadGrid is defined with several GridDropDownColumn. The GridDropDownColumns are linked to an ObjectDatasource.
<telerik:GridDropDownColumn DataField="MondayId" DataSourceID="oOdsPoste" HeaderText="Monday"
                               ListTextField="Code" ListValueField="Id" UniqueName="Monday">
                           </telerik:GridDropDownColumn>


Is there a way to retrieve all the data of the ObjectDataSource in the ItemDataBound Event of the RadGrid?

Thanks,Steven

Showing nodes with parent id didn't exists in the list

Hi,
I am working on a page which shows hirarchical records through RadTreeList control. Everything looks fine except records with parent id which didnt exists in list. Not sure if this is a limitation of RadTreeList control or if there is any flag which allow to display these kind of records.

I have many records in the table with parent id which didn't exists in the table but we still want to show those records in TreeList control.

To explain the issue, there is test page. As you can see in result, first record ("Appetizers") is not rendering on the page as parent id "Y", didn't exists in list.

Thank you in advance for your help.

RadNumericTextBox not enforcing MinValue and MaxValue
The control is enforcing the min and max when using the spin buttons, however, I can type in values that are below the minimum and then click button to postback.

From what I can tell from the UI, it looks like the control shows the alert that the input is wrong, but the postback continues.

Any ideas on how to block the postback?

Thanks.
