RadAjaxManager and Panel inside a FormView

Hi Folks,

I have a FormView that contains a RadComboBox named ComboBox1 and a few other controls which I need to show or hide based on the ComboBox1 selected value using SelectedIndexChanged event.I put those controls inside a panel named Panel1.
This is the setting in the code behind:

protected v

oid Page_PreRenderComplete(object sender, EventArgs e)

{

RadComboBox item1 = (RadComboBox)MyFormView.FindControl("ComboBox1");

Panel panel1 = (Panel)MyFormView.FindControl("Panel1");

RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(item1 , panel1);

}

When I run the app and change the combobox1 value, I get this error: Unknown runtime error.
debuged it the error comes from

"updatePanelElement.innerHTML=rendering;" line

The thing is it works when I use another control but not the panel inside the FormView.

Thanks in advance for your help.

ControlButtons to work for Up, Down

Hi,

I have implemented the control Buttons

<telerik:RadRotator ID="rrRotator" runat="server" RotatorType="SlideShowButtons" ScrollDirection="Up,Down"

Width="300px" Enabled="True" ItemHeight="90px" ItemWidth = "300px"

BorderStyle="None">
<ItemTemplate>

<asp:Label ID="lblPayee" runat="server"><%# DataBinder.Eval(Container.DataItem, "payee_attention_name")%></asp:Label>       <asp:Label ID="lblCity" runat="server"><%# DataBinder.Eval(Container.DataItem, "payment_city")%></asp:Label>
</ItemTemplate>
<ControlButtons LeftButtonID="prevButton" RightButtonID="nextButton" />

</telerik:RadRotator>

<div>
<asp:Image ImageUrl="Images/previousSlide.gif" ID="prevButton" AlternateText="Previous Slide"

runat

="Server" Height="34" Width="33" Style="border: 0px" /> <

asp:Image ImageUrl="Images/nextSlide.gif" ID="nextButton" AlternateText="Next Slide"

runat

="Server" Height="34" Width="31" Style="border: 0px" />

</div>

I have set the scroll direction to 'Up, Down'. I still see the arrows and my image buttons do not work for Up and Down. Please let me know if there a solution for this? Also, Can I scroll more than one data at a time?

advice on how best to put a grid inside a user control

Hi

I have a grid that i use on several different pages. Naturally i don't want to keep copying the grid formatting and template definition and item data bound events from page to page so i thought i would put it in a reusable control.

The problem i am facing is that the different pages that use the control display different sets of data so the logic in the NeedDataSource event is completely different on the different pages.

Could i do something like bubble up the NeedDatasource event so it is handled by the page that uses the control. That doesnt seem a very nice design. Certainly doesn't seem in keeping with the whole principle of information hiding and the like but it's the only thing i could think of

any other suggestions heartily welcomed!

Images on items created with the Client API

I have been working with the PanelBar for the last few months with no problem. However I have just tried to create the items dynamically using the Client API. For some reason an image has been attached to the item. This image is the logo from the top left RadPanel of the screen (if I set display=none on it the logo in the top left radPanel disappears). This only applies to those created using the Client API.

Here is the code used to create the items:

var links = $find("LinksPanel");

var parent = links.findItemByValue("LINKS");

    var item = new Telerik.Web.UI.RadPanelItem();
    item.set_text(displayText);
    parent.get_items().add(item);

The problem also appears on the online demo (tested under IE7 and FF3). I am using 2009 Q1.

The demo (http://demos.telerik.com/aspnet-ajax/panelbar/examples/clientside/clientsideapi/defaultcs.aspx), when clicking to Add At Runtime creates an item which includes the logo. When a postback is performed (on the demo), the panelbar item loses the image and appears as it should.

Any help would be greatly appreciated.

[Solved] Fixed Column Width & No Wrapping

I would like to have fixed column widths on a grid and not allow a row to wrap onto multiple lines. The way I've achieved this is to:-

1. Set TableLayout="Fixed"

2. Set fixed sizes in the ColumnCreated event...

        If (TypeOf e.Column Is GridBoundColumn) Then
            CType(e.Column, GridBoundColumn).HeaderStyle.Width = 140
            CType(e.Column, GridBoundColumn).DataFormatString = "<nobr>{0}</nobr>"
        End If

3. Apply a CSS Class to ItemStyle and AlternatingItemStyle...

            <ItemStyle CssClass="grid-row" />
            <AlternatingItemStyle CssClass="grid-row" />

4. My CSS Class is defined as follows...

            .grid-row td {overflow:hidden;}

Is this the best way to achieve this or is there a built in way or preferred way?

Thanks
