See items below, I tried to keep the ordered 🙂

• Widget.Packages collection is already built to guarantee the sequential loading of the resources (js and css) and it will call the init() method only after the successful loading of all packages. When you use dynamic loading (i.e. adding <script) tags, the browser loads all of the at the same time, that’s why you need a special loader to load them sequentially – which is what Wisej does already).
• Here https://github.com/iceteagroup/wisej-extensions you will find lots of extensions that use external libraries in a very simple way: add the resources to the Packages collection. Wisej also takes care of loading the same resource only once using the name field as the key. We use the same system for very complex libraries (with hundreds of files all as embedded resources in a dll) with the entire DevExtreme, Syncfusion, KendoUI, and Infragstics set of widgets fully integrated (available for Technology Partners).
• You can use webpack, npm or typescript with Wisej. They have nothing to do with the dynamic loading of javascript. One cleans up your references and packages the files, the other is a distribution system, the third is a javascript pre-processor that is also integrated in VS (browsers cannot use typescript). All Wisej needs is a js file. How you build it is irrelevant.
• All Wisej controls and components (including Widget) have Call(), CallAsync(), Eval() and EvalAsync(). The Application object also has a global Call(), CallAsync(), Eval() and EvalAsync(). With Wisej the server can call the browser and the browser can call the server using [WebMethod] which also creates the equivalent js method in two flavors, adding the “Async” postfix for async method. Both Call() and Eval() take a second optional parameter that is a callback with the result since it’s obviously an async operation. Alternatively you can use await with the Async version and get the result without a callback (in reality it’s the same, but this is about the async/await compiler “trick”). https://docs.wisej.com/api/wisej.web/general/control#call-function-args and https://docs.wisej.com/api/wisej.web/general/control#callasync-function-args , etc.

Example for the last point:

private void async button1_Click(object sender, EventArgs e)
{
    var result = await EvalAsync("return 3+2;");
    AlertBox.Show(result.ToString());
}

Hi Cristian,

It doesn’t call Main() again because it’s reloading the previous session and state of the application.

There are a few ways you can deal with this:

1. Check out the Wisej Application class (ApplicationRefresh event): https://docs.wisej.com/api/wisej.web/general/application
2. You can add your query string logic in the Form / Page Appear event.

Let me know if you have any other issues or questions about this!

Best regards,

Hi Nello,

Yes you can!

There are a few ways to do it:

1. Theme Builder
   1. You can add a style to SplitPane > Splitter
   2. See attached screenshot
2. Somewhere in your code:

var splitContainerComponents = Application.Theme.Appearances.splitpane.components;
var splitContainerHorizontalStyle = splitContainerComponents.splitter.states["horizontal"].styles;
splitContainerHorizontalStyle.backgroundColor = "blue";

3. Using a Mixin:

1. Check out the attached project (Add a mixin file to /Themes)
2. Set the appearance key of the control.

Let me know if you have any questions or issues!

Hi Wilfred,

You can use the Theme Builder to do that (see attached screenshot).

Add transform (x) to the error provider style. You can set an appropriate pixel or percentage offset.

If you don’t want to use the theme builder, you can also use a mixin!

https://docs.wisej.com/theme-builder/theme-elements/appearances

Let me know if you have questions about how to do it.

Hi Jan,

glad to see you starting to explore Wisej in detail. Find my answers here:

1. You can install a developer license on up to 3 devices as long as they are used by the same developer.
2. Online and offline license activation is described in detail here:
   https://docs.wisej.com/docs/getting-started/license-activation
3. Each server (IIS instance) requires a Wisej server license.
4. Yes, each developer license includes a server license that can be used for non production servers (like test or develop)
5. No it´s not mandatory. You can turn it off in default.json or have it automatically fall back to http if the server does not support web sockets.
   For load balancing just make sure to have “sticky sessions” enabled.
6. We suggest using KendoUI for jQuery. We offer a) integration training for Telerik and b) the almost complete set of KendoUI widgets integrated as a premium extension.

Bests regards

Hi Anz,

Check out the Application class here:

https://docs.wisej.com/api/wisej.web/general/application

I think you’ll find a lot of what you’re looking for in Application.Browser.

Here’s information on getting the client IP address:

For information on JavaScript execution, check this out:

Let me know if you have any questions!

Hi Ulisses,

You just need to add a “StyleSheet” control from the toolbox and set the source to your CSS file.

I’ve reattached your sample with the fix!

https://docs.wisej.com/api/wisej.web/general/control#cssclass

Best regards,

Levie

Yes you can set it per cell, column, row, all grid, inherit it etc. Look at  https://docs.wisej.com/api/wisej.web/lists-and-grids/datagridview/wisej.web.datagridviewcellstyle#wrapmode

Hi Pontus,

You can change it at design-time using the toolbar at the bottom of the designer window. It shows “blue-1” in the ComboBox by default.

You will also need to change it in the web.config file under the appSettings key.

If you’re trying to change the theme at runtime you can use Application.LoadTheme(themeName);

You can also customize the look of individual controls using Mixins, read more here:  https://docs.wisej.com/theme-builder/

If you have any other questions, please let me know!

Best regards,

Levie

The activation is done through an http rest request on 80.

You can pre-activate it on a different server (not localhost, you can use 127.0.0.1 to use a localhost and trigger the activation) and deploy wisej-server.lic with the project at the same level as Default.html.

Ciao Messere,

It looks like with your application you have a few options…

You can set the “Selected” property of each ListViewItem to False in a handler (SelectedIndexChanged or similar). You would probably want to have different images for a disabled state. The downside of this option is you’ll still have the focus indicator around the item and have to manage the logic for the disabled state.

Another option would be to use a FlowLayoutPanel or FlexLayoutPanel with three buttons in it. The Wisej.Web.Button control has the “Enabled” property that would provide the exact behavior you’re looking for. You can play around with the FillWeight and FlowBreak properties to achieve the sizing and layout you want.

My recommendation would be to use the FlowLayoutPanel with the buttons in conjunction with a custom Mixin (see https://docs.wisej.com/theme-builder/getting-started/edit-a-mixin). With the mixin you can define a custom look for each state (disabled, hovered, etc.) of the button.

I’ll look into adding an Enabled or Selectable property for the ListViewItem. It might be something we want to add.

HTH,

Levie

Ciao Alessandro,

You can do something very similar with the Wisej.Web.DataRepeater control.

Here’s a live demo:

http://demo.wisej.com/DataRepeater/

There’s also a sample project in this forum post:

https://wisej.com/support/question/how-can-i-populate-a-datareader

Would this work for you?

Best,

Levie
