Using Radgrid with normalized table structure

This is a basic design question on using radgrid with normalize table structures from sql server. This is a basic enough question it seems that I should have already solved the problem, but I seem to be having trouble coming up with the answer.

I have a table that has fields that are smallint type that contain Key values from a lookup table.
When in edit or insert mode I use a radcombobox to display the text from the lookup and with the valueField being the lookupID
When in view mode, I don't want to display the smallint values as they are meaningless to to the user. I have gotten around my problem by displaying the radcombo box disabled to get the display values I want but is not visually appealing.

How have others solved this problem using normalized tables as the datasource.

LoadState of Persistencemanager does not work with dynamically created Tiles

Dear Telerik Team

I want to create a page, where the tiles are loaded dynamically from the database. Therefore I added a RadTileList, a RadPersistenceManager and a CustomStorageProvider. When I drag the tiles, the xml will be saved into the database in the correct format.

After calling the page again the tiles should be shown in the same position. Therefore I use the LoadState() method of the Persistencemanager. The xml string is loaded in the right format and with right information into the RadPersistanceManager. But after rendering the page, only one tile is shown. Although all tiles has been successfully loaded into the RadTileList before.

Thank you for your help
Greetings

Javascript error while transferring elements

Hi,

We are facing a strange issue with List box recently. We have a list box in our application for assigning the users to some groups. We wrote the server transfer event for transferring the user because while transferring the user we need to check some condition in the back end. It is working fine for last 2 years. Recently when we transfer the user to the destination list box, it is giving following java script error and transferring functionality is not working.

"Uncaught Sys.WebForms.PageRequestManagerServerEroorException: Sys.WebForms.PageRequestManagerServerEroorException:
511.8182 is not a valid value for Int32"

(Attached Image)

the value is not always 511.8182. It is variable.

this issue is coming in Chrome browser only and in some systems only.

We didn't update any telerik dll recently.

StyleSheetManager Folder?

I get the below error when trying to use the StyleSheetManager

The 'Telerik.Web.UI.StyleSheetFolders' key is missing from the <appSettings /> section of the application's web.config file.
This setting is required when registering external style sheet files in RadStyleSheetManager.

<telerik:RadStyleSheetManager ID="oStyleSheetManager" runat="server">

<StyleSheets>

<telerik:StyleSheetReference Path="css/DivRoundedCornerBlack.css"/>

</StyleSheets>

My RadTreeList has seven columns and I have added functionality to Export the treelist to Excel. How can I exclude a column for being exported, i.e. I have columnA, columnB, columnC, columnD, columnE, columnF, and columnG but when exporting, I do not want columnF to be exported.

Is this possible? If yes, sample code would be appreciated

RadGrid Multiple Rows-Selecting [SHIFT] event

Hello,

I am working on a project with a RadGrid.

The user can select rows. However, there is a limit to the number of rows the user can select.
If the user selects more than the limit, a message pops-up telling the user about the limit. Then, all the rows surpassing the limit are unselected.

I have implement the JS function OnRowSelecting.

function Row_Selecting(sender, args) {

var grid = $find("<%=MyGrid2.ClientID%>");

var masterTable = grid.get_masterTableView();

if (masterTable.get_selectedItems().length >= MAX_NUMBER) {

alert("you reach the maximum number);

args.set_cancel(true);

}

I have a problem when the user selects multiple rows with SHIFT, the above message shows on each row, surpassing the limit.

How can I catch the SHIFT-SELECT event, so I can pop-up the message only once, and not for each row?

Thank you,
Daniel.

Multiple simultaneous Ajax requests

Hi,

I have read that this may be possible by setting the queuing on radAjaxManager? I have:

- A button that is ajaxed to start a server-side process
- A timer that is ajaxed to read progress from the process above and update a label

It appears to me that only one ajax process can run at a time because the timer stops firing while the other process is running?

Sticky footers and RadComboBoxes

I've implemented a RadCombobox inside a sticky footer in a RadPageLayout. The issue is that when one scrolls the main content, the dropdown also scrolls! Now I resolved that matter this way:

.rcbScroll

{

position:fixed !important;

width:410px !important;

bottom:80px !important;

}

.rcbHeader

{

position:fixed !important;

bottom:153px !important;

width:410px !important;

}

.rcbWidth

{

background-color:White !important;

width:425px !important;

}

And everything works great! Except there's one issue... there's a RadGrid in the main section which has a row count / page combobox... and that too uses the RadComboBox, so it gets placed where the sticky footer's combo box goes! Is there a way to resolve this issue?

I'm hoping this is enough info, but I'll be happy to give more if required. Many thanks for any assistance you might have.
