Multiple Themes on the Same WinForm - Is it Possible?

Hello,

I am using ThemeResolutionService to apply theme of entire application.
But there is a special area on certain form of my application and I want to use a custom theme for that special area (RadPanel).

But when I use a ThemeResolutionService, this approach overrides my custom theme for that RadPanel.
Is there any way to achieve this goal?
Thanks.

I think I miss something but what ?

Inherits GridViewDataColumn

Public Sub New(ByVal UniqueName As String, ByVal fieldName As String)

MyBase.New(UniqueName, fieldName)

End Sub

Public Overrides Function GetCellType(row As Telerik.WinControls.UI.GridViewRowInfo) As System.Type

If TypeOf row Is GridViewDataRowInfo Then

Return GetType(ProcessProgressionCellElement)

End If

Return MyBase.GetCellType(row)

End Function

End Class

Private Class ProcessProgressionCellElement

Inherits GridDataCellElement

Public Sub New(ByVal column As GridViewColumn, ByVal row As GridRowElement)

MyBase.New(column, row)

End Sub

Protected Overrides ReadOnly Property ThemeEffectiveType As System.Type

Get

Return GetType(GridDataCellElement)

End Get

End Property

Private StateProgress As RadProgressBarElement

Protected Overrides Sub CreateChildElements()

MyBase.CreateChildElements()

StateProgress = New RadProgressBarElement() With {.Maximum = 4}

Me.Children.Add(StateProgress)

End Sub

If value IsNot Nothing AndAlso value IsNot DBNull.Value Then

Me.StateProgress.Value1 = If(value > 0, value, 0)

Me.StateProgress.Value2 = If(value < 0, Me.StateProgress.Maximum, 0)

Me.StateProgress.Text = helper.GetDescription(CType(value, Process_Prospection.StatuProspection))

Me.StateProgress.IndicatorElement1.BackColor = If(value <> 4, Color.FromArgb(153, 238, 158), Color.FromArgb(153, 225, 238))

Me.StateProgress.IndicatorElement1.BackColor2 = If(value <> 4, Color.FromArgb(8, 208, 4), Color.FromArgb(4, 187, 208))

ReportViewer

First of I'm not sure if this belongs in the Winforms or Reporting Forums, so I apologize if its in the wrong area.

I have just recently purchased telerik to use in my applications and that being said i would like to keep my application mainly using telerik controls eliminating Infragistics and Crystal Reports. I am currently working with Telerik Reporting and have a designed a simple report and created a radform with the reportviewer to load the report however in the past I am used to using the following for loading a crytal report.

DateTime StartDate;

DateTime EndDate;

BuildDate(cboDate.Text, out StartDate, out EndDate);

if (cboDate.Text == "Range")

{

StartDate = new DateTime(dtpStart.Value.Year, dtpStart.Value.Month, dtpStart.Value.Day, 0, 0, 0);

EndDate = new DateTime(dtpEnd.Value.Year, dtpEnd.Value.Month, dtpEnd.Value.Day, 23, 59, 59);

}

using (ProductionService service = new ProductionService())

{

DataTable results = service.Report_BillingReport(StartDate, EndDate);

results.TableName = "BillingReport";

//results.WriteXmlSchema("C:\\ESS\\ESSProduction\\Reports\\DataSet\\Billingreport.xsd");

Reports.BillingReport water = new Reports.BillingReport();

water.Load();

water.SetDataSource(results);

frmReport rpt = new frmReport();

rpt.LoadedReport = water;

rpt.StartDate = StartDate;

rpt.EndDate = EndDate;

rpt.ShowDialog();

}

now i do not believe that i need to set the data source on the click event because the report itself has been attached to the openaccess entity object as will all of the reports. However I am trying to figure out how to use a single reportviewer that has been created for opening multiple different reports I.E. Setting the reportsource for the reportviewer at the click_event and then showing the viewer. Currently where i have my code after reviewing multiple different posts and tutorials mostly for web based applications i have come to the following code:

private void radLabel1_Click(object sender, EventArgs e)

{

Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();

instanceReportSource.ReportDocument = new Reports.JobStatusReport();

Reports.ReportViewer f = new Reports.ReportViewer();

f.Show();

}

Thanks in advance for the help.

[Solved] Collection was modified; enumeration operation may not execute.

We have some users who are occasionally receiving the following error message. There's a few radio buttons on one of the screens in our application, and when the user clicks a radio button, it triggers a new datasource to load into the radgrid. Most of the time it works fine... I'm not sure from the error message what might be going wrong on occasion. Any insight is appreciated.

The version of Telerik.WinControls we're currently using is 8.2.0.0.

Collection was modified; enumeration operation may not execute.

Problem with Copy / Paste timestamp cell - seconds not included

Hi

I have the following problem when copying a timestamp cell value in gridview.
The cell value looks like this - "02-04-2013 12:05:06"
After i copy the cell value to clipboard the result is this: "02-04-2013 12:05" (My seconds is missing)

I have used

radMobilityGrid.Columns[0].FormatString = "{0: dd-MM-yyyy HH:mm:ss}";

to format my column correctly

Can anyone please help me, so that seconds (and milliseconds) will be included when i copy to clipboard?

Kinds regards

/Kristian Theilade
