See attached sample.

Hi Huynh,

a simple merge of 2 pdf memory streams is not possible.
There is a lot of alternate solutions available.

Find one here for example:

Hi,

wisej.web and wisej.core have been consolidated into wisej.framework
when we moved from Wisej 1.x to Wisej 2.x

For more information see here:

Look at the user agent returned by the device using Application.UserAgent. Looks like some Huawie devices return a user agent without “Mobile” in it: See https://github.com/faisalman/ua-parser-js/issues/351

See if there is “MediaPad” or “HUAWEI”. You can add multiple options to the “userAgent” regex:

“userAgent”: “(Mobile|MediaPad|HUAWEI)”

Hi Cristian,

you use Call or Eval, see here:

Hi Andrew,

One issue is related to the framework, not exactly a bug, but it can be improved on our side.  This is what’s happening.

Your code uses a static data source, a true static shared among all sessions. When you change a field in the data source it fires a number of events that allow the data-bound controls to update their content, in this case the data grid. However, being static, the event is originated by the the thread that modified the property. When the handler is called out-of -bound (from a different thread) it doesn’t have the context (session) so the changes to the grid are not sent to the browser. You need another round of changes to update the client.

One way to solved it is to attach to the BindingComplete event and make the grid reload it’s content (dataGrid.BeingUpdate(); dataGrid.EndUpdate()). But this will cause all the cells to be reloads also when you change only one. Our data grid has a special optimization that allows it to update a single cell value (up to a threshold after which it refreshes).

A better way is to create a new BindingSource like this:

public class MyBindingSource : BindingSource
{
   IWisejComponent context;

  public MyBindingSource(object dataSource) : base(dataSource, null) { }

  protected override void OnListChanged(ListChangedEventArgs e) {
    if (this.context == null)
      this.context = Application.Current;

    Application.RunInContext(this.context, () => { base.OnListChanged(e); });
  }
}

This will save the current context when created, like this:

   dataGridView1.DataSource = new MyBindingSource(_listForDGV);
   dataGridView1.DataBindingComplete += DataGridView1_DataBindingComplete;

Now each grid has it’s own BindingSource with the correct context but it still uses the same shared data source.

Then in DataGridView1_DataBindingComplete you can do simply this:

private void DataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
  Application.Update(this);
}

Basically now all the grids will get the updates automatically in the correct context since they share the same data source through a BindingSource that fires the OnListChanged event in context also when being generated from another request’s thread (which can be a different session).

This will be improved internally in all data bound controls in Wisej allow using static data sources more easily.

The CurrentProfile object refers to the current profile that matched the device out of the ClientProfiles.json – it’s to the description of the device. To read the properties of the device use Application.Browser.

If the matched profile doesn’t specify the landscape property it’s left undefined (null, it’s a int?). When set to true (or false) it adds a matching condition to the profile meaning that that the height > width or viceversa, otherwise it’s ignored.

Client profiles are matched from to bottom and the first that matches is used (it’s not a best match selection). You can define a custom set of rules, add a new ClientProfiles.json to your app (Add -> New Items -> templates) to override the built-in one:

{
 "profiles": [
 {
 "name": "Phone",
 "maxWidth": 450
 },
 {
 "name": "Phone (Landscape)",
 "landscape": true,
 "maxWidth": 600
 },
 {
 "name": "Tablet",
 "maxWidth": 800
 },
 {
 "name": "Tablet (Landscape)",
 "landscape": true,
 "maxWidth": 1024
 }
 ]
}
