Can't capture traffic from Android device connected to Wi-Fi with peap mschapv2

Hi Ivan,

When monitoring Mobile Traffic, I recommend that the Machine running Fiddler and the Mobile Device be on the same network. Additionally, the Wi-Fi Network should be visible to the Network that the Machine running Fiddler is on. See the Configure Fiddler for Android and Configure Fiddler for iOS documentation for more information.

There are additional considerations for mobile devices as well and I have listed them below.

1. Android 7+ doesn't allow User-Installed Certificates which means HTTPS decryption will not work. See the Using Fiddler with iOS 10 and Andoird 7 post for more information.

2.Certificate Pinning will also disallow any SSL to read some Mobile Application traffic.

If the issue still persists, can you provide more information about the current set up?

Please let me know if you need any additional information. Thank you for using the Fiddler Forums.

Fiddler does not work with corporate proxy - cannot chain to upstream gateway

Hi Dan,

From my limited understanding, iBoss a comprehensive cloud Firewall/Gateway and has the capability to set user and group policies. It could be that they System Proxy Settings are being controlled by iBoss. If that is the case, the settings would need to be configured in iBoss.

With that said, it may be possible to configure the System Proxy to use the Automatic Config Script and then run Fiddler with the Use System Proxy setting. See the below screenshot for an example.

Please give this a try and let me know the results. Thank you and I look forward to your reply.

Telerik.Common is disabled - extension can't be installed

Hi David,

You can take the following steps to re-enable it:

  1. Expand the the VS Menu bar > Extensions menu
  2. Select "Manage Extensions..."
  3. In the search box, search for "Telerik"
  4. When you find the item, there should be an Enable button

To help guide you, here's what the list may look like when you filter by "Telerik":

Fresh Start

In newer releases of the Telerik VSExtensions releases, there isn't a separate CommonPackage anymore, so it might be worth uninstalling them all so that the common package is removed. Then, you can reinstall it via the Progress Control Panel (select "modify" next to the item you want to add "Visual Studio  Support" for) or just re-run the Test Studio installer.

Further Assistance

If you have any further trouble, reply back with the details of your Visual Studio installation. You can copy the details easily by doing the following:

  1. Open VS Menu > Help > select About Visual Studio
  2. Click the "Copy Info" button on the right side
  3. Paste that information in a code block, or attach it in a text file, in your reply.

I hope I was able to help get you back up and running.

It will probably seem odd for me to say this, but I do not have access to VS, which would be required to build a Execution Extension.

Indeed, it seems that the OnBeforeTestListStarted()method would be helpful. I will see what I can do.

Failed to identify private key location for Root Certificate - CertEnroll and MakeCert failing

I have Fiddler setup as a reverse proxy to capture request and responses from my app. While my app is working, it's not capturing any requests and response, and I'm getting these errors in my fiddler log. I tried CertEnroll and MakeCert but both throw different errors.

I tried searching for this error and I read this article but I don't know what the issue is:
https://www.telerik.com/blogs/faq---certificates-in-fiddler

How can I fix these errors so Fiddler can capture my requests and responses in my app?

Radgrid Column width problems, please help!!!

Hi Ghostho,

RadGrid columns have many Resizing Features. I recommend using the Column/Row Resizing demo and adjusting the configurations to find the desired style. In this case, I believe setting the Allow Column Reszing, Enable Real-Time Resizing, No Wrap for Cell Content and Allow Resize to Fit properties will meet the desired style.

For additional information, see the Column Resizing documentation.

I hope this helps. Please let me know if you have any additional questions. Thank you for using the UI for ASP.NET AJAX Forums.

Hi everyone,

I have updated the telerik reporting version from R1 2019(13.0.19.123)  to R2 2019 (13.1.19.618) version. I use Visual Studio 2017 but can't see into Report Designer for VS2017 the JSON datasource or CSV Datasource.  I mean are these features only appear in Standalone Report Designer or they has been included into Visual Studio Report Desginer?

See image #1 and #2 attached in order to see what is the popup I see in VS Report Designer when I try to connect with a Service.

 

Thanks,

How to select the first item after the Read() is completed

Hi Aleksandar,

 You are right that the index.cshtml containing the treeview is a partial view.

 While your sample works, it still wouldn't help in my case.

 I ended up performing the event binding in the script & it works. (Note: i must say this is after much trial & error as i am very new in ASP.Net core & javascript)

$(document).ready(function () {
        // Note: use local treeview variable.
        var treeview = $("#machinesTreeView").data("kendoTreeView");
        treeview.bind("dataBound", onDataBound);
        treeview.bind("select", onSelectMachine);
    });

 

It is perhaps worth pointing out that the treeview is created inside a Splitter pane.

<divclass="k-content wide">
@(Html.Kendo().Splitter()
              .Name("splitter")
              .Orientation(SplitterOrientation.Horizontal)
              .Panes(panes =>
              {
                  panes.Add()
                  .HtmlAttributes(new { id = "machinesPane"})
                  .Size("200px")
                  .Collapsible(false)
                  .Content(@<divclass="pane-content k-content">
                        <h3>Machines</h3>
                        @*Tree view of machines*@
                        @(Html.Kendo().TreeView()
                            .Name("machinesTreeView")
                            .DataTextField("MachineName")
                            .TemplateId("treeview-template")
                            .DataSource(dataSource => dataSource
                                .Read(read => read
                                    .Action("Machines", "MachineDetails", new { productionLineName = Model.ProductionLineName })
                                )
                            )
                        )
                    </div>);
 
                  panes.Add()
                  .HtmlAttributes(new { id = "detailsPane" })
                  .Collapsible(false)
                  .Content(@<divclass="pane-content">
                      <h2>Please select a machine</h2>
                    </div>);
              })
)
</div>
 
<scriptid="treeview-template"type="text/kendo-ui-template">
    <divclass="d-flex">

            <imgsrc="@Url.Content("#=item.StateIconUrl#")" />

Hi Dimiatr,

   Can the ImageBrowser run as a standalone widget without the Editor in ASP.Net Core?

   There is a link here Using Image Browser Without Editor but it is for ASP.Net MVC.

p/s: i am very new in ASP.Net Core. So do pardon me if i need things to be more explicit.
