Hi Dilyan,

Your attached sample runs excellent. However, as soon as I added the AsyncExportCompleted event handler (line 23, 34 onwards), the screen just freezes. And the control never steps in the AsyncExportCompleted event.

I compared my code with the sample code and they look the same. Any idea what could cause this behavior?

01.privatevoidAsyncExport(objectparam)

02.{

03. stringextension = "xlsx";

04. var args = (object[])param;

05. rgvExportToExcel = args[0] asRadGridView;

06. radDataPager = args[1] asRadDataPager;

07.

08. var dialog = newSaveFileDialog()

09. {

10. DefaultExt = extension,

11. Filter = String.Format("(*.{0})|*.{1}", extension, extension),

12. FilterIndex = 1,

13. AddExtension = true,

14. Title = "Export to Excel",

15. };

16. if(dialog.ShowDialog() == DialogResult.OK)

17. {

18. originalPageSize = radDataPager.PageSize;

19. originalPageIndex = radDataPager.PageIndex;

20. radDataPager.PageSize = 0;

21.

22. GridViewSpreadStreamExport spreadStreamXlsxExport = newGridViewSpreadStreamExport(rgvExportToExcel);

23. spreadStreamXlsxExport.AsyncExportCompleted += SpreadStreamXlsxExport_AsyncExportCompleted;

24. spreadStreamXlsxExport.ShowLoadingIndicatorWhileAsyncExport = true;

25. spreadStreamXlsxExport.RunExportAsync(dialog.FileName.ToString(), newSpreadStreamExportRenderer(),

26. newGridViewSpreadStreamExportOptions()

27. {

28. ShowColumnHeaders = true,

29. ShowColumnFooters = true,

30. ExportDefaultStyles = true

31. });

32. }

33. }

34. privatevoidSpreadStreamXlsxExport_AsyncExportCompleted(objectsender, System.ComponentModel.AsyncCompletedEventArgs e)

35. {

36. radDataPager.PageSize = originalPageSize;

37. radDataPager.PageIndex = originalPageIndex;

38.}

Hi Rumen,

I have sent you the docx file for which formatting and casing are lost on copy-paste. Also, I have tried pasting the data in the DIV/IFrame of the test dojo project but there also the formatting and casing are lost.

Nisheet

Button click event
Protected Sub ExGridPagingBtn_Click(sender As Object, e As System.EventArgs) Handles ExGridPagingBtn.Click
ExGrid.PageSize += 50
ExGrid.Rebind()
End Sub

In ExGrid_NeedDataSource

Protected Sub ExGrid_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles ExGrid.NeedDataSource
If Not Session("ExGridDatas") Is Nothing Then
ExGrid.DataSource = Session("ExGridDatas")
End If
End Sub

Note: ExGrid_NeedDataSource got 6,00,000 rows

I am trying to center a funnel chart in a div, but it doesn't work with my css. It would work well if I use other svg in a div. It looks like that the svg for the unnel chart always start from the point(0, 0) even though I set its margin in css. Much appreciate if any help.

Following is my css

div svg {
    margin-left: auto;
    margin-right: auto;
    display: block;
}

≫ Next: Filter menu events not invoke for RadGrid FilterType of "HeaderContext"

≪ Previous: Highlight row on mouseover

Hello, James,

Currently, the approach with custom renders is the suggested one as well. The main reason is that in the React world the validation is mostly main with custom validation components. This is why there are custom reusable components that can be used in multiple Grids to match the design of the application. We design the React Grid to follow the React best practices and approaches instead of trying to copy the jQuery one. We have a wrapper for React of the jQuery to cover these cases, but still, we recommend using the native version whenever possible.

If you have any suggestions for a specific feature that can be helpful in these cases, please let me know. We are open for any feedback as we want the improve the product as much as possible.

As for the side note, as the DateRangePicker has two different inputs, it has two separate properties for both of them:

https://www.telerik.com/kendo-react-ui/components/dateinputs/api/DateRangePickerProps/#toc-startdateinput

https://www.telerik.com/kendo-react-ui/components/dateinputs/api/DateRangePickerProps/#toc-enddateinput

This is an example:

Filter menu events not invoke for RadGrid FilterType of "HeaderContext"

≫ Next: Set GridViewCell's Validation message display trigger

≪ Previous: Required Field in In-line Grid Editing

Hi Attila,

Thank you for replying.

My requiremnent is as follows: using HeaderContextMenu, I want to hide filter options from the filter drop down list according to the data type of the column.

For example, for a numeric field, I use options "GreaterThan", "LessThan" etc. and hide "Contains", "StartsWith" etc. For a string, I use options "Contains", "StartsWith" etc. and hide "GreaterThan", "LessThan".

I am able to do this where the RadGrid "FilterType" is "Classic", but not where the RadGrid "FilterType" is "HeaderContext".
I can see what the problem is. I am interogating "items.getItem(i).get_value()" to get the filter options. But I do not get them where the RadGrid "FilterType" is "HeaderContext". The value I get is "ColumnsContainer".

The images I have already submitted illustrate this (OnClientShowing.png and OnHeaderMenuShowing.png ).
If you can help me get the filter options, that would be a great help.
I am 99% there. The remaining 1% is proving to be difficult.

I have attached a screenshot that shows how I get a value of "ColumsContainer" when I interrogate "items.getItem(i).get_value()" . I will try and post the script in a separate post. I cannot submit it as a file.

I look forward to your response.

Rob

Hi,

I'm using DataValidation in GridView to keep the input away from unexpected errors. But I encountered a tiny defect. The error messages only display when mouse hovering on the top-right corner (it's a red small triangle out there). This makes the user a little trouble when checking the message because he has to move his mouse in a pretty accurate location. In fact, users usually prefer to get the error tip when the mouse enters the cell. Is there any methods to implement this?

Thank you!
