I have a grid within my application that allows only one row to edited at a time. When there are two (or more) concurrent users of the application I have come across this scenario;

// - User A selects a row to edit

// - User B adds a new row above the one currently being edited (in a different instance of the application)

// - User A causes the grid to postback but remain in edit mode. For example, incomplete mandatory fields.

// - User A is now presented with a different row to edit because the index value on the original row has increased by 1 but the EditIndexes value hasn't

Please can someone let me know if this the expected outcome or if I am missing something obvious?

Towards making it easier to provide help, I would like to briefly describe what I want to do with Telerik Grid.

I am developing an application where the grid is used to display 4 rows of 5 columns of thumbnail images. Paging is enabled because there can be a thousand rows of data. There is a caption directly under each thumbnail. There is a hidden field that has the user ID associated with the thumbnail image.

Clicking on the thumbnail, invokes a client side event handler which gets the user ID for that image.  An Ajax call is made to the server with the user ID to get the url of a full size image, and various user data. The full size image and associated user information will be displayed on a separate tab at the end of the Ajax call by JavaScript on the client.

I am using a GridTemplateColumn to allow me to build the more involved grid cell that contains and image, caption, and hidden field HtmlControls with the runat=”server”  

I am assuming that I can either set the grid DataSource property and call the DataBind method or handle this in the NeedDataSource event.

I plan to use the ItemDataBound event to set the alt and url attribute of the <img>tag along with the caption text held in a <div> container. I will also need to set the value attribute of the hidden field to the user ID.

My data source will be a List<AlbumInfoItemCollection> that has four properties. Each property is a get accessor for an AlbumInfoItem. The AlbumInfoItem class has properties that hold all the information necessary to set the url, caption, and user ID.

Basic Problem/Question

My basic problem is when handling the ItemDataBound event, I need to know the syntax to get the row instance of the AlbumInfoItemCollection.

I would imagine that they do exist, but I could not find any examples that did this.

Thanks in advance,
