I have a radgrid in which I am using a custom edit form. When I do anything on the edit form I am getting the error in the screenshot attached to this post. Below is the code for my edit form control and code behind of the custom edit form control.

Any ideas what could be causing this error?

jQuery click event not firing after RadAjaxLoadingPanel returns

Hi there,

I'm handling the client side event 'OnClientHiding'. The event is raised and my code is called. In my code some click events are assigned to some check boxes using jQuery. Unfortunately the click event handlers don't run when I click on the check boxes.

The jQuery code works perfectly when the page first loads. Its when I try and re-initialize the check boxes after a call back that it doesn't run properly.

Do you have any idea how to fix this?

Here is some code...

$(document).ready(function () {
    f();
});

function LoadingPanelHiding(sender, eventArgs) {
     f();
}

function f() {
         $('.selectAll').click(function () {
             alert('Hello world!');
         });
}

Cheers, Ian.

Make use of RadToolTips for Series Items in RadChart

Hi,

I am in the process of developing a custom dashboard webpart in Sharepoint 2010 by making use of RadChart. I need to add RadToolTips to the series items of the radchart showing the values of the series items. I am able to bring tool tips by making use of RadToolTipManager by setting its AutoTooltipify property to true but using RadToolTipManager I am not able to display any image or control the appearance of the tooltip as I could do in ordinary RadToolTip (any html snippet can be included in ordinary RadToolTip).
So can you please tell me a way for showing RadToolTip with an image in it for RadChart Series item (without using RadToolTipManager)? Please respond to this ASAP since I am doing POC for making use of RadChart within Sharepoint webpart.

Note: This RadChart is being used in the Visual Webpart in VS 2010. The version of Rad controls I use is "RadControls for ASP.NET AJAX Q1 2013"

Thanks,
Rahib S.

Entity Binding with CRUD and Relationships

Hi All,

I'm currently trying to make a simple form using the ASP.NET Grid control and I am running into an issue. When I try to use CRUD with the Entity Framework, all the fields that are not relationships to other tables work great, but fields that are relationships don't show up at all. A great example is the Telerik example:
http://demos.telerik.com/aspnet-ajax/grid/examples/databinding/net35datasourcecontrols/defaultcs.aspx

In the second grid, the one that is bound to an Entity, you see that category shows up as an ID. I don't even get this much in my app. I see all the fields except for the Category field. Ideally it would show the name of the category, and then when you do any CRUD operations, it would show the field as a ComboBox.

Is this something that is even possible with the Telerik controls?

Thanks!

Resizing Problem within RadDock

Dear Telerik,

we are using RadSplitter, RadDockLayout , RadDock and RadChart in our application.

We need to set our custom width and height of raddock and radchart when we drop those from radsplitter to raddocklayout.
similarly when dropped from raddocklayout to radsplitter the raddock and radchart within should to width and height of radsplitter.
if we resize raddock then radchart should resize automatically itself.

In ASPX side code :

<telerik:RadSplitter ID="RadSplitter1" runat="server" Height="100%" BorderSize="0"
            BorderWidth="0" Skin="Black">
            <telerik:RadPane ID="RadPane1" runat="server" Width="350px" BorderSize="0" BorderWidth="0"
                Height="100%">
                <telerik:RadSlidingZone ID="RadSlidingZone1" runat="server" BorderSize="0" BorderWidth="0">
                    <telerik:RadSlidingPane ID="RadSlidingPane1" Title="RadSlidingPane1" runat="server"
                        BorderSize="0" BorderWidth="0" Width="300px">
                        <telerik:RadDockLayout runat="server" ID="RadDockLayout1" OnLoadDockLayout="RadDockLayout11_LoadDockLayout"
                            StoreLayoutInViewState="false" EnableViewState="false">
                            <telerik:RadDockZone runat="server" ID="RadDockZoneVertical1" Orientation="Vertical"
                                FitDocks="true" RenderMode="Classic" BorderSize="0" BorderWidth="0" Width="270px"
                                MinHeight="270px">
                                <telerik:RadDock runat="server" ID="RadDock9" Text="Chart 1" EnableAnimation="true"

                                    RenderMode="Classic" Width="150px" EnableRoundedCorners="true" Resizable="true"
                                    DockHandle="Grip" Skin="Black" BorderSize="0" BorderWidth="0" AutoPostBack="true"
                                    UniqueName="raddoc1" CssClass="chartDock">
                                    <ContentTemplate>
<telerik:RadChart ID="radChartJP" runat="server" IntelligentLabelsEnabled="True"
                                           Legend-Visible="true" ChartTitle-TextBlock-Text=""
                                            AutoLayout="false" Skin="Default">
                                        </telerik:RadChart>
                                        </div>
                                    </ContentTemplate>
                                </telerik:RadDock>
</telerik:RadDockZone>
                        </telerik:RadDockLayout>
                    </telerik:RadSlidingPane>
                </telerik:RadSlidingZone>
            </telerik:RadPane>
        </telerik:RadSplitter>

Could you please advise how to achieve the same.
