Rad Confirm

I tried to get a linkbutton's clientID which is inside an asp:datagrid not "radgrid" with below script and I set linkbutton's onclientclick attribute at on itemdatabound, when I click linkbutton inside the datagrid confirmation well shown, but when clicking OK; result is nothing, what is the problem actually, I really want to understand how rad confirm work.

function setButtonClientID(clientID, text, title)
                {
                    btnName = clientID;
                    radconfirm(text, ClientCallback, 480, 180, '', title);
                }

                var ClientCallback = function (arg)
                {
                    //alert('btnName: ' + btnName + ' arg: ' + arg);
                    if (arg)
                    {
                        __doPostBack(document.getElementById(btnName).id, 'Recover');
                        //document.getElementById(btnName).click();

                    }
                }

RadGrid row thumbnails...

Hi,

I am using GridTemplateColumns and am trying to work around an issue.

In each row of the grid I am placing a link - when I mouse over these links I want to display a thumbnail (image) which hovers at the pointer.

Using the regular ASP.NET GridView control this is not a problem, but with the RadGrid I have an issue.

Currently I use css styling to display the thumbnails. When I use this method with RadGrid the thumbnail only displays partially as the thumbnail image appears in the space for the column it belongs to. For example, the image will not overlap the next column, but the image appears behind it instead. In the css for this thumbnail the zindex is set to a large number, but this has no affect with the RadGrid control.

Is there a way I can achieve this functionality with RadGrid?

Many thanks and happy holidays.

KS

Programmatic creation of Grid with Update/Insert/Delete in Hierarchy using Entity Framework

Greetings,

I have been struggling a couple of days now with trying to create a grid programmatically with hierarchy using the entity framework and repository pattern. For example, I am loading Product and Product Details. I am retrieving my datasource using the entity framework. See below for code to get Products and Product Details:

public

IQueryable<Product> GetProducts()

{

var products = from p in db.Product.Include("ProductDetail")

select p;

return products;

}

public IQueryable<ProductDetail> FindProductDetailsByProduct(Guid productID)

{

var productDetails = from pd in db.ProductDetail.Include("Product")

select pd;

return productDetails.Where(p=> p.Product.ProductID == productID);

}

In my codebehind I copied the DefineGridStructure function from the example given in the Grid / Creating Hierarchy Programmatically example: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/hierarchy/defaultcs.aspx In this example, it uses a SQLDataSource whereas I'm wanting to bind the data programmatically. I tried setting the datasource using my GetProducts() function and convert to list and assign to grid. I have two columns ProductID and ProductName in my Masterview and two columns in my Detailview. The grid loads and is populate however, when I try to expand, it does not find the relation key (ProductID) of the Masterview. ProductID is the primary key in my Product table and it is the foreign key in my ProductDetail table.

I am new to using RadGrid and I am not seeing what I am doing wrong. See actual code below and please point me in the right direction. If there is an example that uses both programmatic creation a gird hierarchy and advanced binding I would appreciate if you could forward me the link. All the samples I have reviewed use on one aspect and I am having trouble putting it all together, including the inserts, updates and deletes. My business rules are too complex to simply use an entity datasource control.

Dialogs blank only on secured page

Hi there,

Has anyone come across the situation where a RadEditor is on a page that is being forced to ssl, and the dialogs open up, but are always blank? It seems the control is creating an iframe to "/controls/RadControls/Editor/Dialog.aspx?dialog=ImageManager&editorID=dnn_ctr474_EditHTML_teContent_teContent&useSession=0&sessionID2=ABCSessionID&language=en_US&UseEmbeddedScripts=yes&tabid=86" which I would assume goes through secure, but it shows up blank, I get the message "Do you want to view only the webpage content that was delivered securely?" if I select no, just goes to the blank popup. If I choose yes, meaning don't send the unsecured content, I get a JavaScript error:

Is this an issue you've seen? Any help would be so greatly appreciated as we use the RadControls extensively and absolutely love them.

Appointment Description field missing?

Good day!

I'm trying to follow the online demos on a current project using the RadScheduler, but it seems that the Description field for the Appointment is missing. Was it removed on purpose on the latest version of the RadControls?

Thank you very much.

Specified page size for grid more than number of recores

Hi,
I am creating a radgrid, specifying the PageSize=20 and setting the PagerStyle Mode=NextPrevNumericAndAdvanced

Then, when I have less than 20 rows, no paging controls are displayed, that's fine.
But if I have 25 records it shows me the text box, where customer can specify desired page size. Ok.
If he specify here 30, nothing will change, page size will remain 20. Yes. if he sets page size to 25, all the records will be displayed and paging control disappears. I belive that should happed by default if he specify page size more than records in the grid.
Why it keeps the current page size instead of taking the max number of records as new value?
Am I missing some scenarios where it could be misleading?

Thank you,
Alex.
