I have an 'editor.aspx' page that has some RadEditor controls and an asp:Timer control to perform auto-save.

The editor.aspx page is running inside a RadWindow but when the RadWindow is closed the timer continues running.

Why does this happen? Is there any way to stop the timers, as the Timer control is in 'editor.aspx' but the RadWindow is in the parent aspx page.

Re-Style "Miss Spelled Words" section

How can I restyle the header section where it says "Spell checking mode. Misspelled words are highlighted in yellow."
I have styled the text on my page to be white text with black background. My problem is that the text is also white on a yellow background in the spell check section.

Also how can I change the text to say "Missspelled words are underlined in red."?
I tried using a RadEditor.Main.Resx in the App_GlobalResources folder, but that did not work.

TabStrip content in a a table

Hi masters!

I have created a tabStrip (concretely with 3 tabs). In each I have got different controls, so the height of each pageview differs.

In order to have everything grouped in a table I have created a table without a border in the top, so it seems the content is inside the tab.

I don´t know whether this is the way to do it, or TabStrip has a property to create a table to group the content of each tab in a table.

If so, i would like as well to know how I can adjust the content of each pageview to avoid have a concrete height for every pageview.

I am using 2008 Q3 version.

Thank you.

Ajax Request not ReBinding Grid

Hi

I am using the RadWindow "Edit Dialog for RadGrid" example and all is going well until the ajax request to rebind the grid - i get the following error:

Sys.WebForms.PageRequestManagerServerException: Object variable or with block variable not set.

I believe the section causing the problem is:

function refreshGrid(arg) {

if (!arg) {

$find(

"<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

else {

$find(

"<%= RadAjaxManager1.ClientID %>").ajaxRequest("RebindAndNavigate");

}

}

in the vb pages i have the following code:

Protected

Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest

If e.Argument = "Rebind" Then
RadGrid1.Rebind()

ElseIf e.Argument = "RebindAndNavigate" Then
RadGrid1.MasterTableView.CurrentPageIndex = RadGrid1.MasterTableView.PageCount

RadGrid1.Rebind()

End If

End Sub

I have set RadAjaxManager1 to update RadGrid1 in the RadAjaxManager but get the error - does anyone have an idea why this happens? The database is being updated and the grid displays the correct data once the page is refreshed.

Many thanks in advance

Steve :o)

Export images to Excel and PDF

Hi, I have a RadGrid containing images that I want to export to Excel and PDF. Having done some experimenting and read the forums, I have come to the below conclusions. I would be grateful if anyone could let me know whether or not my conclusions are correct?

1. ExportToExcel will only export images which have a full URL e.g. http://MyServer.MyImage.jpg. It will not export images with a relative URL e.g. ~\MyImage.jpg. In the latter case, red crosses appear in Excel.

2. The reverse is true for ExportToPdf. An image with a relative URL exports fine. With a full URL, I get the following error message:
'Adobe Reader could not open 'MyExport[1].pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).'

I am using the Q2 2008 Rad controls.

Many thanks
Wendy

Need Sample for Row Select Causing User Control Update

I have a situation where I have a page with a splitter on it. In one split pane I have a user control with a radgrid in it. In another split pane I have another user control that will display information based on the selected radgrid row. I'm not sure the best way to have the radgrid row selection trigger an update.

I'm looking for an example where selecting a row in the radgrid can pass a value from that selected row to another user control in another split pane so that it can update its display based on that passed value.

Any good examples out there already?

Also, I have a similar need for another example of a treeview causing a grid to be updated. In a third pane on this screen, if the user selects a particular tree node in a treeview, I need to have that trigger the radgrid to update its display based on the tree node selected.

Thx

ComboBox and EmptyMessage

I'm using a radcombobox to populate items from a database on demand. All works well except for when EmptyMessage is set

The Problem:

On the first attempt to drop the box down, it displays no matches and nothing comes up in the list. The second dropdown attempt everything works perfectly. Happens only when the EmptyMessage property is set. I'm stumped.

----
Here is what my code looks like:

.aspx and javascript

    
            <telerik:RadComboBox ID="cboCities" runat="server" AutoPostBack="True" EnableLoadOnDemand="True"   
        
                                                                        EnableVirtualScrolling="True" Height="200px" MarkFirstMatch="True"   
        
                                                                        OnClientItemsRequesting="OnClientItemsRequesting"   
        
                                                                        OnItemsRequested="cboCities_ItemsRequested" Filter="None" ShowMoreResultsBox="True"   
        
                                                                        Width="240px" Font-Size="X-Small" AllowCustomText="True"   
        
                                                                        EmptyMessage="Type a city name" Skin="Black">  
        
                                                                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                                                                    </telerik:RadComboBox>

    
            function OnClientItemsRequesting(sender,e)  
        
            {  
        
                if(sender.get_appendItems())  
        
                    e.get_context().CustomText="";  
        
                else 
        
                    e.get_context().CustomText=sender.get_text();  
        
            }

Finally the codebehind:

    
            Protected Sub cboCities_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)  
        
                    Dim sql As String = "Select cityCode,cityName,State,Lat,Long from s_CityMaster WHERE Cityname LIKE '%" + e.Context("CustomText").ToString() + "%' ORDER BY CityName" 
        
                    Dim adapter As New SqlDataAdapter(sql, ConfigurationManager.AppSettings("BioDiasporaCS"))  
        
                    Dim data As New DataTable()  
        
                    adapter.Fill(data)  
        
                    Try 
        
                        Dim itemsPerRequest As Integer = 10  
        
                        Dim itemOffset As Integer = e.NumberOfItems  
        
                        Dim endOffset As Integer = itemOffset + itemsPerRequest  
        
                        If endOffset > data.Rows.Count Then 
        
                            endOffset = data.Rows.Count  
        
                        End If 
        
                        If endOffset = data.Rows.Count Then 
        
                            e.EndOfItems = True 
        
                        End If 
        
                        Dim i As Integer = itemOffset  
        
                        While i < endOffset  
        
                            cboCities.Items.Add(New RadComboBoxItem(data.Rows(i)("cityName").ToString(), data.Rows(i)("cityName").ToString()))  
        
                            i = i + 1  
        
                        End While 
        
                        If data.Rows.Count > 0 Then 
        
                            e.Message = [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", endOffset.ToString(), data.Rows.Count.ToString())  
        
                        Else 
        
                            e.Message = "No matches" 
        
                        End If 
        
                    Catch 
        
                        e.Message = "No matches" 
        
                    End Try 
        
                End Sub

Can anyone help me with what I'm doing wrong? Thanks in advance.

Binding Navigate URL Within A RadGrid ItemTemplate

Hi,

I have a RadGrid and I am using the ItemTemplate to display the data in a table format for each record of data. This allows me to set it out how I want it.

In my table I have included a Rad Menu which I want to use to give the user a number of options. I am having difficulty in assigning the NavigateURL of each menu item. For example I have a button with Text "Edit Details" and I want this to like through to a page called

EditDetails.aspx?ItemID=##

where ## is the ID of the unigue record ID as stored in the database.

I found this post

Binding NavigateURL within a RadGrid won't work

Which is extreemly useful, however the example given has the menu in a GridTemplateColumn, whilst mine is not in a GridTemplateColumn but rather is in an ItemTemplate

When I replicate the code I get the link

EditDetails.aspx?ItemID=

but it does not bring through the ID of the column itself and add it to the address

How do I adjust the code for the example above so that it works for an ItemTemplate, rather than for a GridTemplateColumn

Many thanks in advance
