Does anyone know a way to show rich text in a RadSpreadsheet cell?
Nothing very complicated, just bullets , bold/italic/underlined , maybe color.

I want to create a class of RadGroupBox that when I drop my class on a form, that there is no "TEXT" value. We use the GroupBox alot in our system, /w out the HEADER TEXT. So far, my attempts have failed. Here is my GroupBy class.
public sealed class NtsRadGroupBoxNoHeader : RadGroupBox
{
#region Public Constructors
public NtsRadGroupBoxNoHeader()
{
Padding = new System.Windows.Forms.Padding(2);
ThemeClassName = "Telerik.WinControls.UI.RadGroupBox";
Text = string.Empty;
AccessibleName = string.Empty;
AccessibleDescription = string.Empty;
((Telerik.WinControls.Primitives.TextPrimitive)(GetChildAt(0).GetChildAt(1).GetChildAt(2).GetChildAt(1))).Text = string.Empty;
}
#endregion Public Constructors
}
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.



I am trying to figure out if updating different packages in my project is possible and would like to find the documentation for my Telerik version. I have a old version and can't find relevant information anywhere.
Is there some legacy page i can view?

Hi Dinko and Team,
As I mentioned in my previous forum, The below code is working in VS 2022 with 2013.3.1.1127 where as throwing stackoverflow exception in VS 2022 with Telerk 2024.1.130.48. Out product code structure is like below and we cannot declare and initialize the datatable globally. If we did that the whole application will get impact . Hence could you please restrict the recursive call of Raddropdownlist.Datasource and Raddropdownlist.SelectedIndex also like Raddropdownlist.SelectedValue. Which I raised in my previous forum
public void fillIndustryProcess()
{
try
{
System.Data.DataTable dt1 = new System.Data.DataTable();
if (dt1.Columns.Count <= 0)
{
dt1.Columns.Add("Industry", typeof(string));
dt1.Columns.Add("ID", typeof(int));
dt1.Rows.Add("USA-0", 0);
dt1.Rows.Add("USA-1", 1);
dt1.Rows.Add("USA-2", 2);
dt1.Rows.Add("USA-3", 3);
dt1.Rows.Add("USA-4", 4);
radDropDownList2.DisplayMember = "Industry";
radDropDownList2.ValueMember = "ID";
}
radDropDownList2.DataSource = dt1; ;//Still stack overflow exception occurring when bind the radDropDownList
radDropDownList2.SelectedIndex = 0;
}
catch (System.ComponentModel.Win32Exception ex)
{
throw ex;
}
}
Thanks,

Hello,
I am trying to drag an item from a form Gridview to a Scheduler control but could not see any Scheduler Dragover event got fired. I have set the Scheduler AllowDrop property to true and my code to initiate the transfer is gridview1.DoDragDrop(sTDF, DragDropEffects.Move). Help is apprevciated.
Thanks

Hi Dinko and Team,
As I mentioned in the previous forum, We need fix for Raddropdownlist.SelectedIndex.
When we set SelectedIndex=5 or some value in selectedIndexchangedEvent then the recursive call is happening for SelectedIndex. So we need to restrict the recursive call for both Raddropdownlist.DataSource as well as Raddropdownlist.SelectedIdex.
private void radDropDownList1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
{
fillIndustryProcess1(); // radDropDownList1.DataSource = dt; when we set Datasource the recursive call is occurring
radDropDownList1.SelectedIdex = 5; // radDropDownList1.SelectedIdex = 5; when we set Datasource the recursive call is occurring
}
public void fillIndustryProcess1()Old Forums in which , Telerik team fixed the RadDropDownList .SelectedValue.
Previous forums in which , Telerik team yet to fix for RadDropDownList.Datasource.
Thanks,
Maheswari
