Hi,

I'm using the HTML5 Telerik Report Viewer R2 2017 for Angular 4.

I was able to set the authentication token through the report viewer's property authenticationToken. But when I load the report in my browser, no Authentication Bearer Token is generated in the Request produced by the report viewer.

The following is the Request Header where the token is supposed to be generated:

Accept: application/json, text/javascript, */*; q=0.01

I have a graph with 2 line series. For one of them I have set Tool tip(both Text and Title Properties)

The tool-tip does shows when I hover over the marker. But it doesn't hide when the cursor is moved or clicked somewhere else.

It throws the below jquery error.

Uncaught TypeError: anchor[0].className.match is not a function
    at init._animationClose (kendo.all.js:17881:50)
    at Object.complete [as completeCallback] (kendo.all.js:17817:26)

we are using Telerik Reporting R1 2017

How is the best way to use the report .trdp files.

All the best practice says to build reports in a class file, and reference that.

I ask because we currently design in a class, then serialise that to an XML file to deploy.

Our report viewer scans the reports folder for these xml files and provided the reports in a drop down.

We then de serialise the report and run. Would be nice to be able to do this with the native report files, and skip the serialise / de serialise process.

But I can t see a way to use the native files in this manner.

Hi,

Is it possible to have fixed size panels in a stand alone report designer and when the content inside is larger than the panel size, to have sliders for the panel like in the attached pic? 

Hello.

There is problem with dynamic creation of table columns in MVC Report. Situation is in the following.

In my Report.cs file I override OnNeedDataSource() method. In it I create System.Data.DataTable, then attach this DataTable to Telerik's table as DataSource.

Code for this methods:

/// <summary>
/// Creates DataTable from ReportRecords
/// </summary>
/// <param name="data">List of ReportRecords</param>
/// <returns>DataTable filled with ReportRecord's values</returns>
private System.Data.DataTable CreateDataTable(List<ReportRecord> data)
{
    System.Data.DataColumn currentColumn = new System.Data.DataColumn("Current", typeof(int));
    System.Data.DataColumn lateColumn = new System.Data.DataColumn("Late", typeof(int));
    System.Data.DataColumn foreignColumn = new System.Data.DataColumn("Foreign", typeof(int));
   
    System.Data.DataTable table = new System.Data.DataTable("table");
    table.Columns.AddRange(new System.Data.DataColumn[] { currentColumn, lateColumn, foreignColumn });

    foreach (ReportRecord reportRecord in data)
    {
        System.Data.DataRow row = table.NewRow();

        row["Current"] = reportRecord.Current;
        row["Late"] = reportRecord.Late;
        row["Foreign"] = reportRecord.Foreign;

        table.Rows.Add(row);
    }

    return table;
}

/// <summary>
/// Assign DataTable as DataSource of dinamically created table in report
/// </summary>
/// <param name="table">DataTable with data to display</param>
private void AddTableToReport(System.Data.DataTable table)
{
    this.tableMain.DataSource = table;

    //create two HtmlTextBox items (one for header and one for data) which would be added to the items collection of the table
    Telerik.Reporting.TextBox textboxGroup;
    Telerik.Reporting.TextBox textBoxTable;

    //we do not clear the Rows collection, since we have a details row group and need to create columns only
    this.tableMain.ColumnGroups.Clear();
    this.tableMain.Body.Columns.Clear();
    this.tableMain.Body.Rows.Clear();
    int i = 0;
    this.tableMain.ColumnHeadersPrintOnEveryPage = true;
    foreach (System.Data.DataColumn dc in table.Columns)
    {
        Telerik.Reporting.TableGroup tableGroup = new Telerik.Reporting.TableGroup();
        Telerik.Reporting.TableGroup tableGroup2 = new Telerik.Reporting.TableGroup();
        tableGroup.ChildGroups.Add(tableGroup2);
        this.tableMain.ColumnGroups.Add(tableGroup);
        this.tableMain.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Inch(1)));

        textboxGroup = new Telerik.Reporting.TextBox();
        textboxGroup.Style.BorderColor.Default = Color.Black;
        textboxGroup.Style.BorderStyle.Default = BorderType.Solid;
        textboxGroup.Value = dc.ColumnName;
        textboxGroup.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
        tableGroup.ReportItem = textboxGroup;

        textBoxTable = new Telerik.Reporting.TextBox();
        textBoxTable.Style.BorderColor.Default = Color.Black;
        textBoxTable.Style.BorderStyle.Default = BorderType.Solid;
        textBoxTable.Value = "=Fields." + dc.ColumnName;
        textBoxTable.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
        this.tableMain.Body.SetCellContent(0, i++, textBoxTable);

        this.tableMain.Items.AddRange(new ReportItemBase[] { textBoxTable, textboxGroup });  
    }
}

But, as result, I achieve values from first colum of my DataTable in every column of my Telerik's table:

Current    Late    Foreign
0         0        0
20      20       20
1        1        1
21      21       21
4        4        4

But values should be the following:

Current    Late    Foreign
0         0        1
20       1        0
1         0        6
21       0        0
4         1        0

Why this happens and how to solve the situation?
