onclientclick and onclick for bt on radajaxpanel

I am brand new to the world of coding web pages and have a question.

I have a table on a RadAjaxPanel. The first column is description labels and a couple of the labels have a button to pop detail. The remaining columns are actually the data we are editing and are a RadListView. When the user clicks on a detail button, we pop a modal window, do some data entry, recalculate and then update and save the information that is being displayed/edited in the RadListView. This all works great unless the user has edited data in the RadListView and then pops the detail before saving the data. If that happens, the detail gets saved, the data being displayed in the RadListView gets reloaded, tweaked and saved basically throwing away any changes the user made and did not save.

To try and get around this, I added an OnClientClick call to a javascript function that would fire the onclick of the forms "save" button and return true so that the detail modal form would fire up based on the onclick event. Well, the onclientclick fires, but then the onclick never does. If it matters, I set the onclientclick event statically and set the onclick dynamically during the page load so I can pass the correct guid as a parameter to the detail modal form. I did this based on info I found that said OnClientClick fires before the OnClick event and the OnClick event fires or not based on the return value of the OnClientClick event.

Any thoughts/comments?

Radgrid paging in Internet Explorer 11

Is anyone else experiencing a problem with paging in a Radgrid when the screen is viewed with Internet Explorer 11? Clicking on the pager imagebuttons for First, Prev, Next, or Last initiates a partial postback but the content of the radgrid do not change.

The paging works fine in current versions of Chrome and Firefox.

This is a .NET 3.5 app using Q3 2012 Telerik Radcontrols. Would an upgrade to Q3 2013 solve the issue?

Binding RadComboBox with ObjectDataSource trough DataValueField="Property.Property"

Hi, I'm trying to bind a RadComboBox with an ObjectDataSource (odsFuenteEmisionAlcance) that returns a List of Objects like these:

List<FuenteEmisionAlcance>

public class FuenteEmisionAlcance

{

private FuenteEmision m_FuenteEmision;

private Alcance m_Alcance;

public FuenteEmision FuenteEmision

{

get { return m_FuenteEmision; }

set { m_FuenteEmision = value; }

}

public Alcance Alcance

{

get { return m_Alcance; }

set { m_Alcance = value; }

}

This is my ComboBox

<telerik:RadComboBox ID="rcbFuenteEmision" runat="server" AutoPostBack="True" DataSourceID="odsFuenteEmisionAlcance" DataTextField="FuenteEmision.Nombre" DataValueField="FuenteEmision.Id" ZIndex="100000" CausesValidation="False" OnSelectedIndexChanged="rcbFuenteEmision_SelectedIndexChanged" EmptyMessage="--Seleccione--" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" OnDataBinding="rcbFuenteEmision_DataBinding"></telerik:RadComboBox

I'm trying to use the DataTextField and DataValueField values from the Property FuenteEmision, but somehow is not getting it, this is what I get:

[NotSupportedException: Object of type HUC.FuenteEmisionAlcance does not have a FuenteEmision.Nombre property.]

Like I show before the object FuenteEmisionAlcance does a have a FuenteEmision property, the combo is able to find it, i've tried using only DataTextField="FuenteEmision" and DataValueField="FuenteEmision" just to try and it does find it, but when it comes to find a property from the property it crashes, is this impossible? or there is another way I can acomplish this.
