Hi there!

Recently i encountered the following error: 'You are trying to use a multi-threaded .NET object in a way that is not supported.  The ABL cannot be called on a thread other than the main thread.'. I've known for a while that the language used in my company doesn't support multi-tread, that's why we usually used the version '20' of the dll's but sometimes the "40" were also usable even being multi-thread. Check the following link for context.

However, after updating the 2020 dll's to the 2023, we've been encountering several problems with the "RadPivotGrid" object. We get constant errors and warnings (like the one i shared). So, I've been trying unsuccessfully to find the '20' version so i can force my company's application to run with a single thread, and i can't find it anywhere.

Can anyone help me find it? Preferably DLL's from the year 2023 and forward.

Thank you.

I have data from a table (child) that may or may not contain values from another table (parent).  When I use the data in the pivot grid, I only see the party field values that exist in my child table, I want to be able to see all the values from the parent table

Example

                  Status      ACTIVE          INACTIVE         DISABLED       CANCELED

Positions

FIRST BASE                    1                           0                           0                    0
SECOND BASE               2                           1                            0                    0
SHORT STOP                 0                           0                           0                    0
THIRD BASE                  10                          10                         13                    12

Is this at all possible, by just feeding the data to the DataSource of the pivot grid?

Thanks

Is there the ability to set the default STEP for a field that has not been used as an aggregate but is in the list for the user to select? We have an AGE field, and when the user drags it to either the ROW or COLUMN, the default STEP is 100. We need it to default to 10. Can we do this programmatically?

TIA.

I am having issues where data getting exported to an XLSX file where some tabs are not getting the data. FileExportMode is set to FileExportMode.NewSheetInExistingFile and the file is not in use.  The weird part, is I can run the code multiple times and each time, it is different tabs that don't get populated. In the end, I  should end up with 14 tabs and I get those 14 tabs, the only thing that is in the tabs, is the headers.  if I export that data for each tabs individual to their own file, the data is there and exported as expected.  Maybe I am missing something?

Another weird part, is when I watch the file exporting (in window explorer), you can see the file go to 0KB. It is really weird

Here is my export code

         List<Tuple<int, string, bool>> jurisdictionTypes =
            new JurisdictionTypeDA().GetJurisdictionTypeKeyValueList();

         foreach (Tuple<int, string, bool> jurisdictionType in jurisdictionTypes)
         {
            RadPivotGrid tempPivotExportGrid = new RadPivotGrid
            {
               ColumnGrandTotalsPosition = TotalsPos.None,
               ColumnsSubTotalsPosition = TotalsPos.None,
               EmptyValueString = "0",
               RowGrandTotalsPosition = TotalsPos.None,
               RowsSubTotalsPosition = TotalsPos.None
            };

            var exportResults = _apportionmentInfoPivot
               .Where(app => app.JurisdictionTypeKey == jurisdictionType.Item1
               .OrderBy(app => app.PartySort)
               .ThenBy(app => app.LegacyKeyValue)
               .Select(app => new
               {
                  jurisdiction_name = app.JurisdictionName?.Trim() ?? string.Empty,
                  party_name = app.PartyName?.Trim() ?? string.Empty,
                  totalvoters = app.TotalVoters,
                  signaturesneeded = app.SignaturesNeeded
               })
               .ToList();

            tempPivotExportGrid.DataSource = exportResults;
            tempPivotExportGrid.RowGroupDescriptions.Clear();
            tempPivotExportGrid.ColumnGroupDescriptions.Clear();
            tempPivotExportGrid.AggregateDescriptions.Clear();

            // Row Information
            PropertyGroupDescription myRows = new PropertyGroupDescription
            {
               PropertyName = "jurisdiction_name",
               CustomName = "Jurisdiction",
               SortOrder = Telerik.Pivot.Core.SortOrder.None
            };

            tempPivotExportGrid.RowGroupDescriptions.Add(myRows);

            // Column Information
            PropertyGroupDescription myCols = new PropertyGroupDescription
            {
               PropertyName = "party_name",
               CustomName = "Party",
               SortOrder = Telerik.Pivot.Core.SortOrder.None
            };
            tempPivotExportGrid.ColumnGroupDescriptions.Add(myCols);

            // Aggregate Information
            tempPivotExportGrid.AggregateDescriptions.Add(new PropertyAggregateDescription()
            {
               PropertyName = "totalvoters",
               CustomName = "Count",
               AggregateFunction = AggregateFunctions.Sum,
               StringFormat = "#,##0"
            });

            tempPivotExportGrid.AggregateDescriptions.Add(new PropertyAggregateDescription()
            {
               PropertyName = "signaturesneeded",
               CustomName = "Needed",
               AggregateFunction = AggregateFunctions.Sum,
               StringFormat = "#,##0"
            });

            tempPivotExportGrid.AggregatesPosition = PivotAxis.Columns;

            // Combine each result into a new tab
            PivotGridSpreadExport spreadExport = new PivotGridSpreadExport(tempPivotExportGrid)
            {
               SheetName = jurisdictionType.Item2,
               FileExportMode = FileExportMode.NewSheetInExistingFile
            };
            spreadExport.RunExport(myExportFile, new SpreadExportRenderer());

            // Send each result to their own sheet
            PivotGridSpreadExport mySpreadExport2 = new PivotGridSpreadExport(tempPivotExportGrid)
            {
               SheetName = jurisdictionType.Item2,
               FileExportMode = FileExportMode.CreateOrOverrideFile
            };
            string newfile = string.Concat(Path.Combine(Path.GetDirectoryName(myExportFile) ?? string.Empty, Path.GetFileNameWithoutExtension(myExportFile)), "_", jurisdictionType.Item2, Path.GetExtension(myExportFile));
            mySpreadExport2.RunExport(newfile, new SpreadExportRenderer());


         }

Due to the nature of the data, I can't share the results, so I will try to re-create this in a temp project.

I have attached a like to a video, you can see at 4 seconds and 9 seconds, the file is emptied (0 KB).

TIA for any help here.

Probably more of a suggestion than a question.

I would like an FileExportMode that is between the 2 existing modes. It creates or overrides the named Sheet in the given XLSX

User could then:

• Export to a named sheet.
• Add another sheet that references the exorted data
• Run the Export again to refresh the data

I would like to know how to access the values that are typed in all the "Value Filter" and "Label Filter" options, which appear in the PivotGrid filters in the RowGroupDescriptions and ColumnGroupDescriptions parts, since I require those values to perform additional calculations.

I have tried to reach the values but I only reach the Type of condition and the value, I provide the code that I use for what I mention:

foreach (PropertyGroupDescriptionBase gd in this.radPivotGrid1.RowGroupDescriptions)
{
ValueGroupFilter Filtroporvalor = gd.GroupFilter as ValueGroupFilter;                    

if (Filtroporvalor.Condition != null)
{
ComparisonCondition condition = Filtroporvalor.Condition as ComparisonCondition;

var condicionaux = condition.Condition;
var valorthan = condition.Than;

switch (condicionaux.ToString())
{
case "Equals":
//Code that performs additional calculations
break;
case "IsGreaterThan":
//Code that performs additional calculations
break;
case "IsDoesNotEqual":
//Code that performs additional calculations
break;
}
}
}

But I cannot reach the other values, for example if I use "Equals", I would also like to obtain the name of the field that is used to perform that condition and so on for the other options of "Value Filter", that field is the one that is you can select in the window that is displayed when the filter is applied:

Thank you for your support.

I know how to sort column chooser for RadGridview:

e.ColumnChooser.SortOrder = RadSortOrder.Ascending

is there a way to sort Field Chooser for RadPivotGrid too?

Hi, good morning.

I am using a Pivotgrid, PivotFieldList and Chartview.

The chartview graphs whatever the Pivotgrid has, but there are times when the Pivotgrid has too many records and the Chartview takes a long time to generate.

As seen in the documentation, a Chartview takes time, because it is recalculating the points to regenerate the graph, after having created it previously.

This has led me to think that if instead of the Chartview graphing the Pivotgrid, it would better graph a DataTable.

My idea is the following:
I already generated a filtered DataTable, the result of the interaction between the Pivotgrid and the PivotFieldList and that DataTable fills the Chartview to generate the graph, I think it would take less time to create the graph, since each time the filtered DataTable would be created.

I was looking at this example that you provide to create a graph from a datatable:
https://www.telerik.com/forums/use-radgridview-as-a-datasource-for-radchartview

But it does not graph as expected, that is, it does not show the graphs the same as when the pivotgrid is filled.

Is it possible to do this, or even if you do, will the graph creation time be the same? Because if so, there is no point in working on this solution.

Thank you very much for your attention.

Hello good afternoon.

I ask for your support, for the following.

In a graph, when there are many elements in X, the labels come together a lot and the text is not understood.

When I apply a configuration by code, the graph does look better:

            horizontalAxis.MajorTickInterval = 10;
            horizontalAxis.TickLength = 10;
            horizontalAxis.TickWidth = 10;

Hi,

I have a pivotgrid table like this:

true  |  vegetables    |   data   |  data  |  data
         |  fruit                |   data   |  data  |  data
         |  subtotal         |   data   |  data  |  data
----------------------------------------------------
false  | vegetables    |   data   |  data  |  data
          | fruit                |   data   |  data  |  data
          | subtotal         |   data   |  data  |  data 
How can i change the row header (true, false that are boolean values) using specifically cellformating?
