Hi,

I’m coming back with a solution to the problem, whose cause and fix turned out to be utterly absurd.

If a SplitContainer contains a TreeView and a Wisej.Web.WebBrowser, and the TreeView has more than 4 nodes, then Wisej.Web.WebBrowser.Eval(js) does not execute.
But if the number of nodes is 4 or fewer, the JS does execute.

This bizarre bug makes it impossible to implement an e-book scenario with a browser and a tree view containing more than 4 topics — which is, to put it mildly, EXTREMELY ANNOYING.

Please find images attached.

Perfect 🙂

It’s not supported.

The closest thing is, you can use a MonthCalendar and set the BoldedDates. You can then theme the background color of the Bolded Dates.

The theme would look like this:
“datechooser”: {
“components”: {
“day”: {
“states”: {
“bolded”: {
“styles”: {
“css”: “{\”font-weight\”:\”900 !important\”, \”overflow\”:\”visible !important\”,\”display\”:\”flex\”,\”alignItems\”:\”center\”,\”justifyContent\”:\”center\”}”,
“backgroundColor”: “green”
},

See attached test case with a modified version of the bootstrap theme.

You could also consider using FullCalendar for something like this.

Hi mgmst,

we need a compilable test case that shows the issue including the URL that you have been testing.
Otherwise we cannot help any further.

When it is in the test application (please find attached), I at least receive “Nothing found” message, which points that JS works.

When it is in a my control for books’ content loading- JS not works at all! Why so? Please advice.

Public Class C_Books_Container
Inherits Panel
Private ОWebBrowser As New CUtils.CInterfaceIni.CInterface.C_Wisej_Web_WebBrowser
Public WithEvents OTV As New CUtils.CInterfaceIni.CInterface.CTreeViewS.CTreeView.CTreeView_basic_01(Guid.NewGuid)
Private OSplitContainer As New SplitContainer

Public Sub New(INOStrURLText As String, INOSTRDelimiter As String, INOSTRDelimiter_Internal As String)
ОWebBrowser.Dock = DockStyle.Fill
OTV.Dock = DockStyle.Fill

With OSplitContainer
.Dock = DockStyle.Fill
.Panel1.Controls.Add(OTV)
.Panel2.Controls.Add(ОWebBrowser)
End With
ОWebBrowser.Url = New Uri(INOStrURLText)
Dim OStringPageContent As String = GetTextFromUrl(INOStrURLText)
F_TableОfContents_Get(OTV, OStringPageContent, INOSTRDelimiter, INOSTRDelimiter_Internal)

Me.Dock = DockStyle.Fill

End Sub

Private Sub OTV_NodeMouseClick(sender As Object, e As TreeNodeMouseClickEventArgs) Handles OTV.NodeMouseClick

Dim searchText = “5”

Dim js As String =
”
var found = false;
var elements = document.getElementsByTagName(‘*’);
for (var i = 0; i < elements.length; i++) {
if (elements[i].innerText && elements[i].innerText.includes(‘” & searchText.Replace(“”””, “\”””) & “‘)) {
elements[i].scrollIntoView({behavior: ‘smooth’, block: ‘center’});
elements[i].style.backgroundColor = ‘yellow’;
found = true;
break;
}
}
if (!found) {
alert(‘Nothing found.’);
}
”

ОWebBrowser.Eval(js)

End Sub

End Class

Javascript is executed by the browser. So I used google and found why your “code” doesn’t work.

Nothing at all, complete silence and darkness.

Hi,

“does not work” means what? Do you get an error in the console?
We need a test case with a clear indication of expected result to check this.

Ciao Gabriele,

I cannot reproduce in 3.5.21 with my Pixel 7 and Nexus6P emulators. What type of device are you using?

Grazie,
Levie

Thanks Alaa for your attention to this.  The solution does work, however, at first startup I get an exception that cannot be caught:  “Cannot read properties of undefined (reading ‘option’)”.  This occurs in your project as well as in mine.  If I set this option after the first appearance, then it does hide the weekend days.

Hi Chris,

I have attached a sample that showcases the required feature.

HTH,
Alaa

Hi Roni,

that’s a website, it’s build with Wordpress + Plugins.
Wisej.NET is for enterprise web applications. Not really related.

You can pass the parameters like this:

Application.Navigate("?mypar=1");

You can then get the values like so:
AlertBox.Show(Application.QueryString.ToString());
returns: mypar=1

And this returns just the value:
string[] values = Application.QueryString.GetValues(0);
AlertBox.Show(values[0]);
returns: 1

See attached sample

John-

Your code does work. See attached test case. I am able to open the Project folder and view the file inside.

Has there been an update to this?

Wisej.Web.SaveFileDialog dialog = new Wisej.Web.SaveFileDialog();
dialog.Roots.Add(new FileSystemProvider(Application.Session[“GlobalProperties.DataFileLocation”] + “Project”, “Project”));
dialog.InitialDirectory = Application.Session[“GlobalProperties.DataFileLocation”] + “Project”;

DialogResult result = dialog.ShowDialog();

No existing files are displayed

__

If we do this:

Wisej.Web.SaveFileDialog dialog = new Wisej.Web.SaveFileDialog();
dialog.Roots.Add(new FileSystemProvider(“./”, “Main_Directory”));
DialogResult result = dialog.ShowDialog();

And the user navigates to the Project folder, then the files in the Project folder are displayed.

__

We do not want users to be able to navigate outside of the Project folder, but we want to display the contents of the Project folder when the dialog is displayed.

I looked at your files- try “url”: “Admin.html” in Admin.json

That works for me.

Attached are the new files added for Admin sub-application.

I even put a breakpoint in the Main method of the Admin.cs file and no matter what I do it never gets in there.
