Reason: update test result.

I managed to install Premier Studio 2015 R1 without any problems. Following information shows the detail of the PC.

• Operating system: Windows 8.1 Pro 64-bit.
• IDE: Visual Studio 2015.

I downloaded the setup file of Intersoft Premier Studio 2015 R1 on October 1, 2015 and able to install the WebUI Studio for ASP.NET on the specified development machine without any problems.

In order to determine what may cause the problem on your end, please allow me to guide you to create a log file.

<setup.exe> /l=<logfile.ext>

In the above example, setup.exe denotes the main setup executable, and logfile.ext is the full path to the desired log file.

Be aware that logging significantly decreases the runtime speeds of an installation.

Example:

1. Create a folder in C:\ and named it as: DownloadedFiles.
2. Add a Text Document file and named it as: LogFile.txt.
3. Open Command Prompt (Admin). Fow Windows 8.1 user, can use this combination key: Win key + X, followed by A.
4. Type cd c:\DownloadedFiles\intersoftstudio2015.exe /l=c:\DownloadedFiles\LogFile.txt. Then Press Enter.

Please note:

• If your logfile path contains spaces, enclose the full parameter (including the leading /l= part) inside double-quotes.
• Specifying a file name only is not allowed. You must specify a full valid path in an existing folder, including drive and directory information.

I tried to reproduce the reported problem in my local test by viewing IntegrationwithWebCombo.NET.aspx WebGrid sample file in IE 11 browser but my efforts were not successful - the page was accessed without any issues.

I would need you to elaborate on your specific scenario and possibly provide us with a simple sample that replicates the problem (or sent the modified sample of IntegrationwithWebCombo.NET.aspx that reproduce the problem) and step-by-step guide that we can use to observe the problematic behavior.

You can try to use the following steps in order to export custom data which is different from the data binded to WebGrid:

1. Add an ASP.NET Button into the page.
2. In OnClick server-side event handler, rebind the custom data source.
3. Programmatically invoke the export grid feature.
4. Rebind the original data source.

The snippet code below shows how.

protected void Button1_Click(object sender, EventArgs e)
{
    // Step 2: rebind the custom data source
    dsNorthwind_ReadOnlyTableAdapters.ShippersTableAdapter daCustomDataSource = new dsNorthwind_ReadOnlyTableAdapters.ShippersTableAdapter();
    WebGrid1.DataSource = daCustomDataSource.GetData(); // set WebGrid's DataSource 
    WebGrid1.RetrieveStructure();
    WebGrid1.RebindDataSource();

    // Step 3: invoke the Export Grid feature
    WebGrid1.ExportGrid(SetDynInfo()); // export grid data

    // Step 4: rebind the original data source
    dsNorthwind_ReadOnlyTableAdapters.ProductsTableAdapter daOriginalDataSource = new dsNorthwind_ReadOnlyTableAdapters.ProductsTableAdapter();
    WebGrid1.DataSource = daOriginalDataSource.GetData(); // set WebGrid's DataSource 
    WebGrid1.RetrieveStructure();
    WebGrid1.RebindDataSource();
}

private DynARInfo SetDynInfo()
{
    // configure the DynARInfo object   
    // as the parameter for the ExportGrid() method

    // need to configure 4 things :   
    // dynInfo.ReportType   
    // dynInfo.ReportPath   
    // dynInfo.IISReportPath   
    // dynInfo.DynPageOrientation

    DynARInfo dynInfo = new DynARInfo("excel", Server.MapPath("~/TempReports/"), "WebGridToExcel");
    dynInfo.IISReportPath = "/TempReports/";
    dynInfo.DynPageOrientation = PageOrientation.Portrait;
    return dynInfo;
}

WebGrid will show Products table. When the button is clicked, Shippers table will be exported.

Hope this helps.

Could you please provide me with following information so that I can investigate the problem further.

• Operating system of your development machine, for example: Windows 10 Pro 64-bit.
• Installed Visual Studio on your development machine, for example: Microsoft Visual Studio Ultimate 2013

Setup file of Intersoft Mobile Studio will add the Crosslight project wizard, CrosslightApp.zip, in this location: "\My Documents\Visual Studio Version\Templates\ProjectTemplates\Visual C#\Intersoft Solutions\Mobile\CrosslightApp.zip". For example: Crosslight project wizard in my development machine can be found in: "C:\Users\MyUserName\Documents\Visual Studio 2015\Templates\ProjectTemplates\Visual C#\Intersoft Solutions\Mobile\CrosslightApp.zip".

When I open Visual Studio 2015, click File | New | Project from the main menu to bring up the New Project dialog. In the left pane under Intalled | Templates chose the Visual C# | Intersoft Solutions | Mobile, then choose Intersoft Crosslight Application (iOS, Android, Windows) from the available templates in the middle pane. The screenshot below shows how.

Look forward to hearing back from you so that I can assist you further.

Overriding CanExecuteDelete can be used in order to prevent delete on item from DataListViewModelBase.

I use MyInventoryWebAPI Crosslight sample and apply this rule: prevent delete on item(s) that have been sold. Note that the Item has a Sold column/field name.

Override CanExecuteDelete and insert following code:

protected override bool CanExecuteDelete(object parameter)
{
    // only return true if item is not sold
	// prevent delete on item(s) that has/have been sold
	// on multiple selection scenario, if any item from
	// the selected item is sold, delete will be disabled
	if (parameter is Item)
    {
        return !(parameter as Item).Sold;
    }
	else if (parameter is IEnumerable<Item> && ((IEnumerable<Item>)parameter).Count() > 0)
		return !((IEnumerable<Item>)parameter).Any(p => p.Sold == true);

    return false;
}

I uploaded the modified version of MyInventoryWebAPI sample at OneDrive: here, as reference. Hope this helps.
