I am attempting to adopt a similar set up using CRUD from Tychobras shiny_crud app
https://github.com/Tychobra/shiny_crud/. Instead of rendering the data table as the main page, I am trying to place it within a tab which will have a surrounding box.
It seems the call to the function which would render the data table to the screen is working correctly because I am able to see the "Add" button but fails to display the data table. I am assuming it is because it cannot reach the database.
This is what it currently looks like
Here is the attached code.
Here is the tab I am working in
R version 4.1.2
Current libraries (all updated most recent)
Here is a snip of how the data frame looks correctly but not inside of the tab
I am trying to update a text dynamically but without success. clicking on a button the text is updated
We have data using DevExpress Grid on a web application, and the users are asking to only export the visible data from the page. At the moment, if we do an export, it exports everything from the grid, whether it is shown on the current page, or on a future page (200 items, 20 pages, showing only page 4, we export everything).
We are using the WritePdfToResponse (if its a PDF file as an example) and tried using the PdfExportOptions PageRange, but it seems to only work for Pages of the PDF file, not the data... For example, if there are 200 items to display, on the site it shows as 20 pages, but in PDF, it shows up as 4 or 5 pages. If we want only page 4, we get page 4 of the PDF, not of the site... Can this be done? Ideally, for PDF, CVS, RTF and XSL...
The grid exporter exports the entire data from the ASPxGridView control. However, if you temporarily bind the grid to a visible page only, and then export it, you will get the same result.
For example, you can get the grid's page index to determine what user sees on the screen and that fetch these records from the datasource.
I assume that you can select required range of rows and set the ExportedRowType property of the ASPxGridViewExporter to Selected.

I want to allow the users of my application to click on a cell in a Flex 4 DataGrid and hit Ctrl-V to paste the contents of the clipboard into the current cell and the cells below it. Basically, what I want to do is select some values from a single column in Excel and paste into a single column in the DataGrid, and this is a web application, not an Air app. Is there an example anywhere of how to do this?
I can grab the contents of the clipboard using keyboard handler events, but I'm not sure how to disable the default paste functionality of the DataGrid. The default functionality is to paste all of the clipboard contents into the selected cell. And I want it to paste into multiple cells starting with the one I have selected.
Any help would be appreciated!!
Thanks,
Steve
What you would do is detect which cell is active, you would then have to catch the ctrl v.
You then need to interrogate the clip board and work out the intent manually, and then set the relevant cell values.
The other option is to interrogate the clip board and then integrate to the data provider.
Please see this sample: http://hillelcoren.com/2009/09/17/import-export-copy-paste-flex-datagrid/
In an AIR application, I have a link button for winner statistics. If I click this button, then the statistics are shown on a full page (Canvas) in my application. I have already created the statistics using the Canvas component. Which container is typically used for viewing such data?
Any references? I tried a ViewStack, but will it overwrite the Main page?
Could you give some more information? If you are trying to show tabulated data, you can try a DataGrid. If you have a component you would like to list, then a VBox would work and you could just add your winner stats component to the list.
