Hello

We recently moved our winform application from standard forms to telerik forms. The application is a tray application, and before moving we used to us about 6MB of memory at startup. This stayed pretty stable.

Since moving, I noticed we are now using 70MB of memory. Because this is a tray app, it could be oped hundreds of times on a single server from different users.

I was trying to figure out what is using the memory, and created a blank winforms form app, and a blank winforms using telerik. I notice a huge immediate difference. The winforms app uses 2MB, the telerik app uses 20MB.

Does anyone have any advise how I can reduced the amount of memory being used in a telerik winforms app?

Many thanks

Localization in Composite Filter dialog

Hello,

I'm using Telerik version 2017 R2 for app.

I followed this guide to localize all texts as well as labels in Composite Filter (custom filter) dialog, please see my result below

Composite Filter Localization result

As you see:

1. The texts in GREEN rectangle are localized successfully by adding the prefix "FR_".

2. The texts in rectangle are not localized because I don't know exactly the Localized String Id to override the default text.

Please advice! Thanks a lot!

SelectedValue not set to null

I used BindingList for data binding,

BindingList<Person> personList = new BindingList<Person>();

radMultiColumnComboBox1.DataSource = personList;

RadMultiColumnComboBoxElement multiColumnComboElement = this.radMultiColumnComboBox1.MultiColumnComboBoxElement;

multiColumnComboElement.EditorControl.MasterTemplate.AutoGenerateColumns = false;

GridViewTextBoxColumn column = new GridViewTextBoxColumn(); column.HeaderText = "ID";

column.FieldName = "id";

column.Name = "colId"; multiColumnComboElement.Columns.Add(column); column = new GridViewTextBoxColumn(); column.HeaderText = "Name"; column.FieldName = "name"; column.Name = "colName"; multiColumnComboElement.Columns.Add(column);

Let Person object have two properties, id and name. I set ValueMember to id and DisplayMember to name.

And I set the SelectedValue,

radMultiColumnComboBox1.SelectedValue = person.id;

This is working correctly. But when person.id become null, SelectedValue is not null, instead it select first item of BindingList<Person>.

I can't understand why. Pls answer to me.

RadTextBoxControl - How to use linked ImageList

I can see that there is an option to link ImageList to RadTextBoxControl but there are no options to use the images of said ImageList. Am I missing something? I don't see any properties to mention the index of the ImageList.
