[The “custom viewer” error maybe a problem with Visual Studio. I don’t know what it means to open a datatable while debugging.]

It’s not a Visual Studio error, because it only happens with Wisej.

To reproduce the error just create a Datatable (here I do it with a query select)

DataTable oSelect = Leo.mytable(“select * from customer”);

If you block the execution and try to see the contents of the Datatable, as you see in the attachment, you receive the error (I translated it from Italian)

Use “d”  as the format, see https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-date-and-time-format-strings

You have to download it. Look at the Application.Download methods in the docs. There is also a client file system api (it’s documented on mozilla) that you may use but requires additional permissions.

in general browsers don’t have access to client resources without the proper javascript api.

Hi,

Looks like you have WebSockets disabled? you can verify that by checking the Console in DevTools or checking Application.IsWebSocket.

If that’s the case, you’ll need to do the following modifications:

private async void upload1_Uploaded(object sender, UploadedEventArgs e)
{
Application.StartPolling(100);
await ProcessUploadAsync(e);
Application.Update(this, () =>
{
MessageBox.Show("Upload completed…");

Application.EndPolling();
});
}

You need to use Application.Update()
Documentation: https://docs.wisej.com/api/wisej.web/general/application#update-context-action

You could do it like this:
private async void upload1_Uploaded(object sender, UploadedEventArgs e)
{
await ProcessUploadAsync(e);
MessageBox.Show(“Upload completed…”);
Application.Update(this);
}


But ideally, you would put the MessageBox call inside the Application.Update() call to insure that the UI is updated when the call ends.

private async void upload1_Uploaded(object sender, UploadedEventArgs e)
{
await ProcessUploadAsync(e);
Application.Update(this, () => { MessageBox.Show(“Upload completed…”); });

}

Thanks for the sample. If it helps, the mixin from your sample does work to turn node text red when selected- as long as the HTML isn’t affecting the text color.

For example, if you use HTML to underline the text, your mixin will turn it red on hover:

treeView1.Nodes.Add(new TreeNode("<span style= \"text-decoration: underline\">Node 1</span>") {AllowHtml = true});

I tried this before.

This approach only works for normal nodes (without html).

Please see my example.

If you are using the ThemeBuilder to edit your themes, you will notice that under “Tree Node” there is an option for “textColor” under “selected”
The JSON for it would look something like this:


"tree-folder": {
"text": "Tree Node",
"components": {
"states": {
"default": {
"properties": {
"textColor": "",
"indent": 18,
"icon": "icon-folder",
"opacity": 1,
"padding": [2, 0, 2, 0]
},
"styles": {
"backgroundColor": null
}
},
"hovered": {
"styles": {
"backgroundColor": "hotTrack"
},
"properties": {
"cursor": "pointer"
}
},
"selected": {
"properties": {
"textColor": "YOURCOLORHERE"
},
"styles": {
"backgroundColor": "highlight"
}
},

Hi Daniel,

You can create a custom Theme, or write a Theme Mixin.

A Mixin basically overwrites the appearance on any Theme you choose, and it would make sense to use it for your use case since you’re going to target a single control.

For more information, please check out our documentation https://docs.wisej.com/theme-builder/getting-started/edit-a-mixin

Sorry but I don’t understand, I start from your standard project, this is automatically inserted in my Web.config:
<add key=”Wisej.DefaultTheme” value=”Bootstrap-4″/>
I don’t change anything at all, but to follow your instructions I added (but I don’t understand what it’s for) the line in the code:
Application.LoadTheme(“Bootstrap-4”);
How can I use two different themes? Remember that they are always in Visual Studio, not on the server. You just sent me directions to change the theme, but I don’t do it.
Where am I wrong, if I’m wrong?
Thank you.
Francesco

Hi Francesco,

you’re using a different theme at design time vs runtime.

PS: You can delete obj/bin folders before uploading here.

I ran your sample and was able to reproduce- looks fine when running from Visual Studio but the top of the toolbar gets cut off when deployed to IIS. We’ll look into this.

Set the Size and do not set AutoSize to true. Also set the Autoscaling to None, the default I believe if Font which autoscales if you change the font of the panel at runtime to something different than the original one. There is no dpi scaling since dpi scaling makes no sense in a browser.

When you set the Size nothing in Wisej.NET will change the size of your control. The only properties that change it are Anchors and Dock but you should set those unless you want to alter the size based on the container’s layout engine.

https://docs.wisej.com/docs/concepts/layouts

This is a Workaround, but not ideal solution:

string cReport = “myreport.rpt”;

CrystalDecisions.CrystalReports.Engine.ReportDocument myReport = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
myReport.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperA5;
myReport.Load(cReport);

myReport.SetParameterValue(“var1”, “Value variable 1”);
myReport.SetParameterValue(“var2”, “Value variable 2”);
myReport.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, “test.pdf”);

pdfViewer1.PdfSource = “test.pdf”;

Just a quick note that Wisej.NET 3.2.6 was released today.
