problem trying to display "No records to display" on page load

Hello

I am having problems trying to display the message (or a custom message) "No records to diplay" in the radgrid when my page first loads.

I have tried putting in this code on the page load event:

If Not IsPostBack Then

rgListingWithImages.DataSource =

New Object() {}

'rgListingWithImages.Rebind()

End If

but I get this error.
Both DataSource and DataSourceID are defined on 'rgListingWithImages'. Remove one definition.

Here is my radgrid code:
***************************************************************************************************************************************************************

RadEditor ImageManager Paths

I am developing an internal web application and when I upload an image using RadEditor Imageupload, it successfully gets uploaded to a virtual directory in the web application. The application creates a document and it can be viewed by anyone outside the network.

So when I insert the images, it reference the virtual directory which is only accessible internally.
So when people outside the network views the document, they are unable to see the images in the document since the image reference is set to the virtual folder.

I can copy the images in the virtual folder to a folder that is accessible from www. In that case how can I change the image reference to point to the external image.

for example.
Image upload folder in only Internal
~/images/a.jpg

I can copy this a.jpg to another server which is available externally.
Say I copy access the image using
www.test.org/images/a.jpg

How can I change the image reference from ~/images/a.jpg to www.test.org/images/a.jpg/

please let me know.
thanks

editor.pasteHtml is inserting <STRONG> tag before Paragraph

Hi,

I want to set styles to Paragaraph, I am able to set the styles but after setting style the selected paragraphs are becoming bold. Editor is adding <Strong> tag to the selected Paragraphs. Please tell me any work around for this, or is it issue in Editor when we do PasteHtml with P tags. This happens for P tags

My Code is as below:

var cssTextFormed = "text-align:"+textAlign+";line-height:"+lineSpace+";text-indent:"+hanging+"; margin: "+ beforePara+ " "+ rightindents +" "+ afterPara +" "+ leftindents +";";

var editor =$find("RadEditor1");

//if more than one paragrah is selected then replace p tag with applied style
var selection = editor.getSelectionHtml().replace(/<P/g,'<P style='+cssTextFormed);
editor.pasteHtml(selection);

rad window keeps loading on post back

Hi all

I have a dilemma with a rad window. Here is an example.

I have grid and some buttons on a page. I am opening the radwindow from a link button in the grid using the ItemCommand event in code behind.

Here is the code where I open the radwindow:

Protected Sub rgListingWithImages_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgListingWithImages.ItemCommand

Dim value As String = Nothing

Select Case e.CommandName

Case ("DeleteRow")

'Do something here

Exit Select

Case ("Slides")

'Open the slide window

'RadWindowManager1.Windows(0).Visible = True

Dim newWindow As New RadWindow

newWindow.NavigateUrl =

"http://www.google.com"

newWindow.Top = Unit.Pixel(22)

newWindow.VisibleOnPageLoad =

True

newWindow.Left = Unit.Pixel(0)

RadWindowManager1.Windows.Add(newWindow)

Exit Select

End Select

End Sub

Here is the problem.

The window opens OK form the "Select" command of the grid. However when I click on the "Delete" command of the grid the window opens again and when I click on any other button on my page the radwindow opens.

Is there a way to open the window jsut from the "Select" event of hte grid?

Postback "killing" Textbox-Values

Hi there

I don't think, this is telerik-specific but perhaps you can help me anyway.

I got a Form embedded into a RadAjaxPanel containg some "dumb" TextBoxes and a combobox which initiates a postback:

    
             <telerik:RadAjaxPanel ID="FormPanel" runat="server" OnAjaxRequest="formPanel_AjaxRequest"> 
        
             <telerik:RadTextBox ID="txtUniqueName" runat="server" Width="240" /> 
        
            <telerik:RadNumericTextBox ID="txtILN" runat="server" Width="240" MaxLength="13"  NumberFormat-GroupSeparator="" Type="Number" MinValue="0" NumberFormat-DecimalDigits="0" /> 
        
            <telerik:RadComboBox ID="cbxLanguage" runat="server" Width="240px" AutoPostBack="true" OnSelectedIndexChanged="cbxLanguage_SelectedIndexChanged" />

(I removed Table-/TR/TD and other stuff)

When selecting the Combobox a postback is initiated (as expected and wanted). But before this happens I can still enter some stuff into the textboxes. But these are emptied when the Postback finally takes place.

Any idea how to solve that issue or at least disable the comboboxes for that period of time?
