I'd like to nest a RadListBox in my RadGrid.  How can I link the parent RadGrid to the child RadListBox.  I tried using the "ParentTableRelation" code from below, but its not working.


Is this something that needs to be done in the code-behind?

I'm creating a new web application with Entity Framework. I want to use the following layered structure:

User Interface Layer

Business Object Layer

Interface

Entity Framework Layer

The Business Object Layer now implements the interface on bottom layer using the Entity Framework Objects.

In the user interface I use a Telerik component (radGrid) to show/edit/update/delete data. Now I can show entity data to user simply doing a simple (linq to entities) query like:

 var stabilimenti = from s in entities.Stabilimenti
                               select s;

My problem is to persist data on database when user changes them.

In my user page i want to catch the "RadGrid1_UpdateCommand" and in some way persist data modification. Debugging i've seen that at the update event i've lost all data modification (the program executes a Page_Load just before).

How can I persist modification? Have I to use an Entity DataSource and manually place there datas retrieved from Entity Framework entities? Or what else should I do?

 

Hi,

I am trying create a RadGrid by using clientside databinding feature.
My requirement
1. To display first few columns with the data retreived from database using the GridBoundColumn
2. The last 2 column should have "Select" and "Delete" hyperlink. On clicking this hyperlink i need to call the javascript to do some action in the client side. Also the javascript should have a knowledge on which row i clicked.

The problem i am facing
1. I tried with the GridClientSelectColumn but the problem is, RadGrid display only checkbox eventhough i set the ButtonType="LinkButton". I don't know how to display the "Select" text. I was expecting it to show the "Select" text by default or atleast to display the text defined in the "Text" attribute.
2. GridClientDeleteColumn displays the "Delete" link but i am not able to bind the column value to the CommandArgument so that i can know which row is clicked.
3. Also in both the option when i databind the Grid in the client side, both the column doesn't display the text. It first apears and then disapears after the client databind.
4. So I tried with the GridTemplateColumn with the html control in the ItemTemplate but I am not able to bind the data using 
        <telerik:GridTemplateColumn>
               <ItemTemplate>
                      <a href=javascript:rowSelected('<%# Eval("Text") %>') >Select</a> 
                </ItemTemplate>
         </telerik:GridTemplateColumn>
binder, because the data is not displayed.

Could you please let me know some solution or show some pointer to some sample for the following,
1. I want to display a grid with client side databinding with last 2 columns "Select" and "Delete" link button and on clicking this link i should call the javascript with the row information passed to the method.

Thank you for your support.

For instance in the http://demos.telerik.com/aspnet-ajax/treeview/examples/applicationscenarios/directorystructure/defaultcs.aspx, if you click several times very quickly on the Custom Attributes folder the loading indicator keeps being shown. I'm trying to find a suitable solution for this by using hideLoadingStatus() but it just hides the last Loading indicator that was loaded and the other ones stay there.
Any ideas?

I am planning to construct Radscheduler in the "Class Detail Schedule" section. As you might can see from the code, other control is referencing user control. Is there anyway to build RadScheduler in the page without using user control. how it can be implemented and how to assign the datasource. thanks

Hi  folks, this is particularly difficult to explain, however I will try by best

I have attached code and sample output.  I have a binary image control in a column.  I load the control for each row in the grid and it displays correctly.  When I click on a row the corresponding PDF document is displayed correctly. however, the grid looks empty but the contents have actually moved way down the page.  Could you please tell me what I am doing wrong?

Thanks

{
    DocGrid = sender;
}
function DocRowSelected(sender, eventArgs) {
    // alert("Click on row with index: " + rowIndex);
    var MasterTable = DocGrid.get_masterTableView();
    var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];
    var path = MasterTable.getCellByColumnUniqueName(row, "DT_FilePath").innerHTML;
    var Filename = MasterTable.getCellByColumnUniqueName(row, "DT_FileName").innerHTML;
    var Pgm
    Pgm = "DisplayDocument.aspx?File=" + path + Filename;
    open(Pgm);

Dear team,

I want to use the form template in radgrid edit mode to include the upload from the GridAttachmentColumn. I am using the form template becaue it gives me more flexibility.  Howver, i tried to use the radupload control but  i did not know how to access the binary data inorder to assign it to a byte field. Can you tell me how to format and place the upload field that is imbedded in the 

GridAttachmentColumn.

Thans in advance
