I need a ComboBox column initialized with some data and the user can enter new data too when inserting new row into grid. For example, ComboBox column has three items by default Phone, Mobile, Fax, but the user needs to insert new item (e.g., Code). How can I do this?

Here is the code. With this code the user can only select one of the default values of combo column and he/she cannot enter his/her new value into combo column.

DataTable table = new DataTable();

table.Columns.Add("Name", typeof(string));

table.Columns.Add("Value", typeof(string));

var details = db.BatchItemDetails.Where(d => d.BatchItem_Id == _id)

.Select(d => new { d.Name, d.Value });

foreach (var row in details)

table.Rows.Add(row.Name, row.Value);

grid.MasterTemplate.AutoGenerateColumns = false;

grid.DataSource = table;

GridViewComboBoxColumn name = new GridViewComboBoxColumn();

name.DataSource = (from b in db.Batches

join i in db.BatchItems on b.Id equals i.Batch_Id

join d in db.BatchItemDetails on i.Id equals d.BatchItem_Id

where b.Id == batchId

orderby d.Name

select d.Name).Distinct().ToArray(); // string array.

name.AutoCompleteMode = AutoCompleteMode.Suggest;

name.DropDownStyle = RadDropDownStyle.DropDown;

name.Name = "Name";

name.FieldName = "Name";

name.HeaderText = "عنوان اطلاعات";

name.Width = 219;

name.TextAlignment = ContentAlignment.MiddleLeft;

grid.Columns.Add(name);

grid.Columns.Add("Value", "شرح اطلاعات", "Value");

grid.Columns["Value"].Width = 353;

grid.AutoSizeRows = true;

RadForm Right-to-Left Layout

Hi,

It seems that when setting both "Right to Left Layout" and "Right to Left" properties of the RadForm to 'True' the border of the form is drawn incorrectly, with the left side of the border disappearing.

Also, I am using the theme Office2007Blue.

Roy.

[Solved] Disposal of pages closed by user

Hi, i would like to know if when a user close a page on the pageview, the controls inside this page will be dereferenced (thus become eligible for garbage collection) or if I have to handle the closed event and manually remove all the controls inside the page.

Also would like to know if there is something I can do to cleanup removed pages or if the removed pages are automatically managed by the pageview control or if i have to call dispose on the page itself in the closed event.

It's just to be sure not to lock too much memory for too long time, i did not find a documentation page about this.

Best regards

Andrea

Vertical LinearGauge unable to properly draw 13 in certain circumstances

Hello, I am evaluating your demo software and found a peculiar bug in a vertical gauge that has a needle indicator. It is the gauge that has the needle indicator that points at a value of 66 in the 'Select a gauge type from gallery' window. If I set the RangeEnd property of the gauge to 14 and the RangeStart to 13, it correctly draws the the 13. If I set the RangeEnd to any number greater than 13 but less than 14, the RangeStart text incorrectly draws. It appears as if multiple paint events are occurring on top of each other on the RangeStart text property. It is easy to replicate. Unfortunately this is a range I need to operate in as I plan to monitor a barometric pressure sensor that reads between 13 and 14 and need more fine detail than a difference of 1 gives me (14 - 13). Ideally, I'd want the RangeStart to be at 13.4 and RangeEnd to be at 13.8.

Localization with Progress Developer Studio 11.6.2

Hello,

I made some tests with the trial version (2015.02...) shipped with Progress Developer Studio and with this Version the localization worked. Now I purchased a regular Version (2016.02.....) and installed it. I build a complete new Form with a RadDock (correct version 2016.02...) in it an tried the localization in the following steps, which work with the 2015.02 Version

1. in the Using section:

USING Telerik.WinControls.UI.Localization.RadDockLocalizationProvider.

2. in the Constructor:

RadDockLocalizationProvider:CurrentProvider = NEW Basis.DockGermanLocalization().

After typing "RadDockLocalizationProvider:" the Dev.Studio proposes me the property "CurrentProvider". The form compiles with no errors. Running the form gives me then following error:

"System.MissingMethodException: The method "Telerik.Controls.UI.Localization.RadDockLocalizationProvider.CurrentProvider" not found"

What did I wrong? Thank you for your answer in advance

Regards

Jürgen
