I am able to put grid into edit mode by using one of the following code snippets. However, i need to edit only some of columns and leave others non editable.

How can i achieve that?

Thank you

For Each item As GridItem In grdContingentDevelopment.MasterTableView.Items
            If item.GetType().ToString() = "Telerik.Web.UI.GridDataItem" Then
                Dim editableItem As GridEditableItem = DirectCast(item, GridDataItem)
                editableItem.Edit = True
            End If

GridDropDownColumn displays more space than needed for records

Why does the GridDropDownColumn display larger than the count of items?

You can see what I mean here http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/columntypes/defaultcs.aspx

Check the RadComboBox Columns example. You see 5 records in the combo, but the combo drop down extends another 4 or 5 records further of empty white space.

How do I fix this?

Follow-Up to Drag n Drop work work.. works in second browser

Follow up to other post

Drag and drop wont' work on one of two web applications using same page

Turns out that the AsyncFileUpload Drag and Drop feature does not work in the first browser the page opens in but it does work in each subsequent browser. It doesn't matter whether Firefox, Internet Explorer, or Chrome is opened first, the control does not work as expected, however when you copy and past the url to the webform in the other two browsers the AsyncFileUpload Control works as expected.

See attached images which show that all three browsers are running the exact same page!!
It doesn't matter which browser you choose to run the application in first; IE10, Chrome, or Firefox the AsyncFileUpload Control Drag and Drop feature does not work. Another odd behavior is that the file select control does not show any mapped network drives to choose files from. You can choose files from the Network neighborhood but the mapped drives do not show-up.

The second and third browsers (doesn't matter which you choose, IE, Chrome, or Firefox) the control works as expected. I'm using the ASP.NET development server rather than IIS. This is on the .NET 4.0 framework. Again, here are the relevant webconfig, markup, and code-behind files.

Any help is much appreciated. Mark-up of aspx page.

<!-- VIEWSTATE LOCATION

The ViewStateLocation specifies where the view state for a page

should be stored.

1. Page (default): Stored it in the page. Increases page size.

Always works, but slower to encrypt, decrypt and send.

2. Session: Store it in the session on the server.

Results in better performance, but may not always work because

session data may be timed out, or flushed to make room for more.

3. Cache: Stored in the cache. Similar to Session, but has more

timeout options.

4. File: Stored in a temporary file. Will always work, but slower.

5. Database: Stored in the database. Will always work, but slower.

See online help for more information.
