Telerik UI for WinForms latest version download
IronPython and the latest Visual Studio 2019 make this possible, and they enable Python desktop applications to be used with WinForms controls. More importantly, Telerik UI For WinForms suite has some ready-made functions to help you achieve the functions you want!
Iron Python
IronPython is a powerful open source version of Python. It is an adaptation of the Python programming language running on the Microsoft .NET framework. IronPython can use the .NET Framework and Python libraries, and other .NET languages can also easily use Python code.
After installing the latest version of IronPython, you can open Visual Studio 2019, which comes with a built-in template project for "IronPython Windows Forms Application" and create your first application.
How to integrate Telerik RadGridView with modern Fluent themes into your application
First, you need to install the Telerik UI for WinForms UI component kit-you can click to download from here , and then add the required Telerik assembly to the project folder to use WinForms' RadGridView, FluentTheme and RadChartView (spoiler alert, later Will need it) control.
To reference a binary file in an application, import the clr library and then use the addReference method. Here you can see how to add the reference and usage required for the sample application.
import clr
import random
clr.AddReference('System.Drawing')
clr.AddReference('System.Windows.Forms')
clr.AddReference('Telerik.WinControls')
clr.AddReference('Telerik.WinControls.UI')
clr.AddReference('Telerik.WinControls.ChartView')
clr.AddReference('Telerik.WinControls.Themes.Fluent')
clr.AddReference('TelerikCommon')
clr.AddReference('Telerik.WinControls.GridView')
from System.Drawing import *
from System.Windows.Forms import *
from Telerik.WinControls import *
from Telerik.WinControls.UI import *
from Telerik.Charting import *
from Telerik.WinControls.Themes import *
Now, let's take a look at how to add a radGridView control, which contains a bunch of different columns.
#Define RadGridView self.radGrid = RadGridView() self.radGrid.BestFitColumns() self.radGrid.ForeColor = Color.Black self.radGrid.Dock = DockStyle.Fill #Define Columns self.decimalColumn = GridViewDecimalColumn() self.textBoxColumn = GridViewTextBoxColumn() self.colorColumn = GridViewColorColumn() self.checkBoxColumn = GridViewCheckBoxColumn() self.ratingColumn = GridViewRatingColumn() self.decimalColumn.HeaderText = "DecimalColumn" self.textBoxColumn.HeaderText = "Text" self.colorColumn.HeaderText = "ColorColumn" self.checkBoxColumn.HeaderText = "CheckBoxColumn" self.ratingColumn.HeaderText = "RatingColumn" self.radGrid.Columns.Add(self.decimalColumn) self.radGrid.Columns.Add(self.textBoxColumn) self.radGrid.Columns.Add(self.colorColumn) self.radGrid.Columns.Add(self.checkBoxColumn) self.radGrid.Columns.Add(self.ratingColumn) self.Controls.Add(self.radGrid) #Populate Rows for index in range(10): self.radGrid.Rows.Add(index, "Sample Text " + str(index), Color.FromArgb(random.randint(1,255), random.randint(1,255), random.randint(1,255)), CheckState.Checked, random.randint(1,100))
The result is a radGridView with the following columns: GridViewDecimalColumn, GridViewTextBoxColumn, GridViewColorColumn, GridViewCheckBoxColumn, GridViewRatingColumn.
As shown in the figure, if you want to apply the theme to the control, you can do it as simple as that.
fluent = FluentTheme () self.ThemeName = fluent.ThemeName self.radGrid.ThemeName = fluent.ThemeName
Subscribe to events and implement your business logic
This is an example of creating a RadButton control and subscribing to its Click event.
#Define RadButton1 self.myButton1 = RadButton() self.myButton1.Text = "RadButton1" self.myButton1.Click += self.OnButton1Click self.Controls.Add(self.myButton1)
Then, you will have to define OnButtonClick logic.
def OnButton1Click(self, sender, args): #TODO OnClick logic
Now, we use the radGridView in the previous example to see a more complex event-related example. We will implement some logic in the CellFormatting event to fill the cells in the GridViewRatingColumn with different colors. The value in the Rating unit can be between 0 and 100, if the value is <50, we will fill these units with red, otherwise we will use the Aqua color. We can achieve this result using the following code:
def OnRadGridCellFormatting(self, sender, args): if args is not None : if args.Column.HeaderText == "RatingColumn" : if args.CellElement.RowInfo.Cells[4].Value is not None : if args.CellElement.Value > 50 : args.CellElement.DrawFill = True args.CellElement.ForeColor = Color.Blue args.CellElement.NumberOfColors = 1 args.CellElement.BackColor = Color.Aqua else : args.CellElement.DrawFill = True args.CellElement.ForeColor = Color.Yellow args.CellElement.NumberOfColors = 1 args.CellElement.BackColor = Color.Red else : args.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local) args.CellElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local) args.CellElement.ResetValue(LightVisualElement.NumberOfColorsProperty, ValueResetFlags.Local) args.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local)
The final result of CellFormatting is this:
RadChartView's Little Bonus Setup example
As you can see in the radGridView example, it is very easy to use the Telerik control. Let's look at another example of using BarSeries to set the radChartView control.
#Define RadChartView
self.chartView = RadChartView()
self.chartView.Size = Size(290, 160)
self.chartView.Dock = DockStyle.Fill
#Define BarSeries and CategoricDataPoints
self.barSeries = BarSeries("Performance", "RepresentativeName")
self.barSeries.Name = "Q1"
self.categoricDataPoint1 = CategoricalDataPoint(177, "Harley")
self.categoricDataPoint2 = CategoricalDataPoint(128, "White")
self.categoricDataPoint3 = CategoricalDataPoint(143, "Smith")
self.categoricDataPoint4 = CategoricalDataPoint(111, "Jones")
self.barSeries.DataPoints.Add(self.categoricDataPoint1)
self.barSeries.DataPoints.Add(self.categoricDataPoint2)
self.barSeries.DataPoints.Add(self.categoricDataPoint3)
self.barSeries.DataPoints.Add(self.categoricDataPoint4)
self.chartView.Series.Add(self.barSeries)
self.Controls.Add(self.chartView)
The result is the same as the Telerik UI for WinForms application you would expect.
