Hi Sushma,

We don’t understand what you are trying to do:

– ajax calls are from the browser to the web server, while the loader is shown on the browser. Using ajax calls to show the loader doesn’t make sense.

– what do you mean with “custom loader”?

if you attach a small test case showing what you need to do would help.

Thanks.

The problem is that Control.MousePosition catches the coordinates that are related to the body of the page. Meanwhile, the labels have coordinates that are related to their Parent, that is chart. Are there any options how to fix this?

Hi Edwin,

if websockets work fine in Chrome for your application I guess we can exclude a server
problem from our research in that case.

For IE and Edge please check their settings, especially the Compatibility Mode and
the Document Mode. It might be running as a lower IE version not supporting WebSockets.

Hope that helps.

Hi Jan,

have your tried using Autosize = true and setting the Minimum Width and Maximum Width to only allow it to grow vertically?
You can also use the AutoSizeMode to GrowAndShrink if you want the panel to shrink, too.

If you want to do your own measurement and resizing you have to measure the HTML text on the client
using Wisej.Base.TextUtils.MeasureTextAsync.

If that does not help, please provide a small test case.

Hi Sushma,

can you please be a bit more precise about what you are missing or trying to achieve ?

Please also have a look at the AutoShowLoader that could help you:

Hi Dmitry,

An easy solution in your case would be to put the labels behind the chart (or panels with labels in them), set the chart’s BackColor opacity setting to 0, and add a click event to your chart with something like the following:

if (this.myLabel.Bounds.Contains(Control.MousePosition))
{
                AlertBox.Show("Clicked the label!");
}

If this doesn’t work for you, we can potentially look at other solutions!

Does this help?

Perfomance meaning speed? No. Memory reduction can be achieved by disposing the forms or pages not used.

Hi Andrew,

The upload control uses the <input type=”file”> element (there is no other way to upload files). Our control (source code is here: https://github.com/iceteagroup/wisej-js/blob/master/wisej.web.Upload.js) attaches the “change” event, reads the files list (see getFiles()) and uses the static method uploadFiles (same js code) to send the file through an ajax request using the FormData javascript class.

On the server side, the request is handled by the ASP.NET file upload handler and you get the uploaded file collection.

If you want to resize the image on the client you have to do it obviously before it is sent to the server. And since the file selected by the <input type=”file”> is not an image yet, you have to create an <img> element (or Image class), load the file, process the onload event to get the image, draw it scaled on a canvas, get the image back as a data uri from the canvas, convert it to a file object and send it to the server. Not too easy.

You can override the upload method in Wisej easily like this:

qx.Mixin.define("my.UploadPatch", {

   statics: {
      uploadFiles: function (files, submitUrl, filter, maxSize, callbacks) {
         
           // process the files
           
           // call the base implementation or replace with a custom ajax request.
           this.base(arguments, files, submitUrl, filter, maxSize, callbacks);

      }
   }

});

qx.Class.patch(wisej.web.Upload, my.UploadPatch);

Hi Hasan, it’s not  a bug. The office viewer from Microsoft needs to access your document and it cannot reach localhost.

Hi HSoft,

The issue has been fixed and will be available in the next development build!  We’ll let you know when it’s out.

Hi HSoft,

Thanks for reporting the issue. I’ve logged it as #2111.

You can add this line to your code as a temporary workaround:

for (int i = 0; i < dataGridView1.Columns.Count; i++)

{

dataGridView1.Columns[i].SortMode = DataGridViewColumnSortMode.NotSortable;

dataGridView1.Columns[i].Update();

}

Let me know if this works for you.

Best,
Levie
