I'm trying to create a Report that has a dynamically generated DataTable as its DataSource.

I’ve programmatically placed a DetailSection on the Report, and added a TextBox for each column of the DataTable to the DetailSection.

The TextBoxes are databinding, but I can’t figure out what the proper Expression would be to access the column data for each TextBox.

The ReportItem.DataObject.RawData for each TextBox is a DataRowView.

In the Immediate window in Visual Studio, I can access the column data from within the TextBox DataBinding handler with the following:

((System.Data.DataRowView)(((Telerik.Reporting.Processing.TextBox)sender).DataObject.RawData))["ID"]

 Please tell me what Expression would access the column data. 

1. it possible to create telerik report programmatically in asp.net core?

2. I need to create teleik report programmatically in asp.net core and to display in html5 viewer?

can you any let me know ans.

Question Details

I have multiple expressions which redo the same calculation several times. 

Part of the calculation uses an aggregated result of a field.

Is there a way to simplify and increase the maintainability of the report by creating a calculated field for a group? This field would be used multiple times in sub-groups and in the detail section.

Please note that I do not have the power to update the source code and because of this I can not create "custom functions". 

I've tried to store the calculated value in an invisible text box but I can't seem to recall this value to be used in subsequent text boxes. 

Very Simplified Example

Let f(x) = Avg( Field.x ) <-- How do I set this in the group header so I can reference it in the detail section?

Let textBox7.Value = "Distance From COM: " + Abs( f(x) - Field.x )

Note: If this is not possible across groups, but it is within a group please let me know. This would also greatly simplify the maintainability of my report. 

Thank you for taking the time.

I would like to populate and disable the From input from the client. I am running into a few issues:

1. It appears the viewer page is blocking the bundled javascript include. As a work around I am including the script file in the header which works fine and acceptable for me.

    <script src="@Url.Content("~/scripts/reportsportal.js")"></script>

2. It appears that something is blocking the ability to bind to the event SEND_EMAIL_BEGIN

ex in my script file reportsportal.js I am attempting to bind to the SEND_EMAIL_BEGIN so that I can populate and disable the FROM input using jquery

However it appears that my script file is getting blocked and the following message is displayed in the browser console:

Autofocus processing was blocked because a document already has a focused element. 

I don't think the script runs at all.

$(document).ready(function () {
    if (reportViewer) {

        reportViewer.bind(telerikReportViewer.Events.SEND_EMAIL_BEGIN, function (e) {
            debugger
            console.log(this.id);
        });
    }


});

3. As a work around to not being able to bind to SEND_EMAIL_BEGIN , I wired one of the declarative events on the viewer widget:

        .ClientEvents(ev=>ev.PageReady("printPageReady"))

In printPageReady I was able to capture the From field with a selector

function printPageReady() {
    var t = $('input[name="from"]')
    t.val('test@yahoo.com')
}

Setting val on input[name="from"] DOES NOT generate any exceptions and checking the variable t in the console shows that a value has been assigned however when the Send Email dialog pops up the From input is still empty.

Is there another approach that I can use to access, disable and populate the From input from the client.

Hello, 

Is it possible for header from subreports do be shown on the main report? I have four different subreports with their own headers and my main report will not have a header (nor title), so I need in my main report to import header + detail section from subreport.

I think I saw that it could be done by reportBook, but that will not work for me. 
Or by some grouping criteria but I am not sure how is that functioning.

Thanks in advance! 

Best regards,
