We use client-side data binding extensively for our "read only" grids and it works great. However, I now have a scenario where I would like to use the RadGrid to edit data.
Is there a way to bind the data on the client side and then put all rows into "edit" mode? I tried the "editAllItems" method on the master tableview but it doesn't actually put the rows into edit mode, it just does a postback telling the grid to do the work on the server.
I want to be able to add, edit (in place) and delete rows on the client without ever generating a postback. All rows should *always* be in edit mode. Is it possible?

Hello Scott,
You cannot use built-in forms for editing when using client-side binding. However the following demo illustrates one possible way to achieve this functionality:

Hi Nikolay,
Thanks for the suggestion. I had seen that demo earlier but it is not the functionality I am trying to achieve.
What I have ended up doing instead is using a standard Repeater to build an HTML table with 50 rows in it. I hide all of the "unused" rows at the bottom using CSS styles. I then "unhide" a row when the user clicks the "add row" button. This works, but it is unfortunate that I have to send 50 rows of HTML (including all of the controls contained in those rows) from the server to the client browser even though the user will probably never need more than 10 or so.
I tried just creating new table rows as needed using javascript (which is not a problem), but I couldn't figure out how to create/clone the RadControls on the client using javascript (I need a combobox, input, and numeric input in each row). So I am stuck sending a fixed number of rows from the server and just hiding/showing rows as necessary.
If anyone has any ideas for how to accomplish this a better way I would love to hear from you.

Hello Scott,
I am afraid that it is very hard to create any IScriptControl( as RadControls for ASP.NET AJAX) on client due to complex rendering and script required for this controls to function properly. Thus the example demonstrates how to overcome this and have external edit/insert forms.

Thanks Nikolay.
I ended up adding/removing rows from a normal HTML table instead. I created regular HTML controls using Javascript then added them to a RadInputManager (also using javascript). It is an acceptable work-around for my case.
Here is a link to another thread with some code samples in case someone is interested:
