Hello,

I'm trying to make sense of the RadWindow/RadWindowManager relation. I see that there can be many RadWindowManager controls defined in one page (unlike the RadScriptManager/ScriptManager which requires one implementation). But I also see that we can implement the RadWindow either inside of the RadWindowManager or as a standalone control.

What is the advantages of using the RadWindowManager beside being able to apply settings defined on the manager to the window? Is it better to keep the RadWindowManager outside of the master page and define it where it is needed, or is it better to keep a global radwindowmanager, and have radwindow as a standalone control?

Thanks.

custom filtering with objectdatasource in .NET 4.0

Hi,

I want to implement custom filtering in my radGrid, but I don't get it to work right now. What I'm trying to do is the following:

I have radGrid and the datasource of the grid is an objectdatasource. In the selecting event of the objectdatasource i add my filterexpression and sortexpression. In the function in my businesslogics, i have the filterexpression, sortexpression, startindex and maximumrows. The filterexpression is coming to the function properly, but i can't get it to work with my entitymodel. I've tried enableLinqExpression="True" and enableLinqExpression="False" but with both options it doesn't work.This is the code of the function:

public static IQueryable<vw_TrainingCompanyLocations> GetTrainingCompanyLocations(string filterExpression, string sortExpression, int maximumRows, int startRowIndex)

{

KolipeEntities db = new KolipeEntities();

IQueryable<vw_TrainingCompanyLocations> data;

if (!string.IsNullOrEmpty(filterExpression))

data = db.vw_TrainingCompanyLocations.Where(filterExpression);

else

data = db.vw_TrainingCompanyLocations;

return data;

}

Do you have any idea how to get this to work?

Displaying MsgBox On TOP of Modal RadWindow

I have a number of forms that open in a modal RadWindow. On the popup window, there are a number of other forms that can be edited individually. When they are saved, I wanted just a standard MsgBox to appear like so:

MsgBox("Information has been updated. ", MsgBoxStyle.Information, "Information Update")

That works fine, however it does NOT open over the top (or take focus) over the RadWindow.

Also, once the user clicks ok on the msgbox, how can I also close the RadWindow?

Rad Editor absolute positioned sub windoes issue

I have a issue where I have the rad editor absolute positioned. When the editors sub windows popup (ex: Hyperlink manager) they are appearing behind the editor. If I drop the z_index down to a low number then they work fine, but that for me would cause a issue. I want to give the editor a higher z-index to make sure of no issues, since other objects can also be absolute positioned on the page and their is a risk of the number becoming higher than the editor z-index. Is there a way to change the sub windows z-index from code or javascript or even a css file to have higher z-indexes?

The same page worked great for years using the 6.5 version of the editor and I never ran into this problem with that editor. However IE 9 doesn't play nice with that version.

Mimic RadGrid filtering

Hello, I'm trying to mimic RadGrid filtering. I would like to have e.g. 3 textboxes with filter button which would work exactly with the same way like RadGrid filtering. The same subset of filtering options and the same filterexpression generated. Could you advice me what is the best way to do so? I would not like to write such functionality from scratch.

Kind Regards
Marcin

All RadControls under IE9 with SSL

Hi,
Using the latest version of your controls 2011.1.315.40 I have an issue where non of the radcontrols display there graphics when used in Internet Explorer 9 and with SSL. If I use any other browser including IE8 all works correctly.

I have attached a picture of what the RadGridView looks like when running under IE9 and SSL. All your controls do the same thing.

Is this a bug or am I missing something.

Thanks

Use of table cells under resource values

Dear Telerik,

I've got three questions concerning RadScheduler. Please, help me with them...

I'm using RadScheduler and show resource values as column names (default behaviour).

I see that there exist empty cells under each cell with resource value (see screen-shot, there I marked one of such cells in yellow)

1) Can I put something in these cells? For example I may need to show not only resource values but some additional attributes of the same resource. These cells would be a perfect place for them.

2) Can I format the text shown as column header (align text, show in bold...)?

3) Can I show more than one property of the same resource in the column header?

Thank you very much!

- Stepan.

NewsRotator to use pages

So i would like to have the newsrotator to use pages, instead of news. I think i have the general idea here but I think i may have something incorrect in the fluent api. I end up getting

Must specify valid information for parsing in the string.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Must specify valid information for parsing in the string.

Source Error:

so in the page load for the rotator i set the rotators data source to use pages that are published

RadRotator1.DataSource =

App.WorkWith()

.Pages()

.Where(n => n.Page.Status == ContentLifecycleStatus.Live)

.Get()

.Take(this.NewsLimit)

.ToList()

.Join(App.WorkWith()

.Images()

.Get()

.Where(i => i.Parent.Title == albumName.ToString() && i.Status == ContentLifecycleStatus.Live),

item => item.Title.Value,

image => image.Title.Value,

(item, image) => new { NewsItem = item, NewsImage = image });

Then under data binding i use page instead of news item

Page newsItem =

(Page)TypeDescriptor

.GetProperties(e.Item.DataItem)["Page"]

.GetValue(e.Item.DataItem);

Since pages has a description and not a summary I would like to use that

if (text != null) text.Text = newsItem.Description;

The target NewsPage uses typeof(NewsView), is there some sort of PageView?

as well as under the rotator when intialize controls i use Pages for the rotators datasource

this.RadRotator1.DataSource = App.WorkWith().Pages().Where(p => p.Page.Status == ContentLifecycleStatus.Live).Get().Take(this.NewsLimit).ToList().Join(

App.WorkWith().Images().Get().Where(i => i.Parent.Title == albumName && i.Status == ContentLifecycleStatus.Live),

item => item.Title.Value,

image => image.Title.Value,

(item, image) => new { NewsItem = item, NewsImage = image });
