1. Target Framework .NET6 and VS 2022 17.0.1:
2. Install UI.for.WinForms.AllControls.Net60 version 2021.3.1123:
3. Double click the form to open the designer:
4. First try dragging a RadGridView from the toolbox:
5. Install the Nuget package for the toast notification:
6. Install Microsoft.Toolkit.Uwp.Notifications version 7.0.0:
Please make sure that the C:\Program Files (x86)\Progress\ToolboxNuGetPackages folder doesn't contain anything and it is empty. If there is any version available there, please delete it.
7. Now, try opening the designer. It never loads:
Use the following code snippet and enter "8,5" in RadMaskedEditBox. Then press Tab to navigate to the next control:
RadValidationRule validationRuleNumberLess;
RadValidationRule validationRuleNumberGreater;
float numberMaximum;
float numberMinimum;
public RadForm1()
{
InitializeComponent();
CultureInfo culture = new System.Globalization.CultureInfo("de-DE");
System.Threading.Thread.CurrentThread.CurrentCulture = culture;
System.Threading.Thread.CurrentThread.CurrentUICulture = culture;
this.radMaskedEditBox1.Culture = culture;
this.numberMaximum = float.Parse("9,999", culture);
this.numberMinimum = 0;
// set maximum
this.validationRuleNumberLess = new RadValidationRule();
this.validationRuleNumberLess.AddControl(this.radMaskedEditBox1);
this.validationRuleNumberLess.Operator = Telerik.WinControls.Data.FilterOperator.IsLessThanOrEqualTo;
this.validationRuleNumberLess.PropertyName = "Value";
this.validationRuleNumberLess.ToolTipTitle = "Too big";
this.validationRuleNumberLess.ToolTipText = "The value must be SMALLER than " + this.numberMaximum.ToString();
this.validationRuleNumberLess.Value = (float)this.numberMaximum + 0.001D;
this.radValidationProvider1.ValidationRules.Add(this.validationRuleNumberLess);
this.radValidationProvider1.SetValidationRule(this.radMaskedEditBox1, this.validationRuleNumberLess);
// set minimum
this.validationRuleNumberGreater = new RadValidationRule();
this.validationRuleNumberGreater.PropertyName = "Value";
this.validationRuleNumberGreater.ToolTipTitle = "Too small"; // this.localToolTipTitle;
this.validationRuleNumberGreater.ToolTipText = "The value must be BIGGER than " + this.numberMinimum.ToString();
this.validationRuleNumberGreater.Operator = Telerik.WinControls.Data.FilterOperator.IsGreaterThanOrEqualTo;
this.validationRuleNumberGreater.Value = (float)this.numberMinimum;
this.validationRuleNumberGreater.AddControl(this.radMaskedEditBox1);
this.radValidationProvider1.ValidationRules.Add(this.validationRuleNumberGreater);
this.radValidationProvider1.SetValidationRule(this.radMaskedEditBox1, this.validationRuleNumberGreater);
this.radLabel1.Text = "Minimum = " + this.validationRuleNumberGreater.Value + " Maximum = " + this.validationRuleNumberLess.Value;
}
Workaround: use the ControlValidation event to control the validation flag: https://docs.telerik.com/devtools/winforms/controls/validation-provider/validation-rules#controlvalidation-event
Create a RadRibbonForm or a RadForm with Ribbon behavior. When you run the application and maximize the form, the titlebar's text disappears.
Workaround: Use a RadForm and add RadRibbonBar without Ribbon behavior. Then set the RadRibbonBar.RibbonBarElement.RibbonCaption.Visibility to Collapsed.
Workaround 2 : set the RadRibbonForm.AllowAero property to false
Hi Sir,
We updated telerik and facing some issues with that.
in new update with rich text editor has new property called MentionBox settings of that auto added in to designer code.
which creates an error when we run the application.
following line is auto added.
mentionBox1.FocusedItemIndex = -1;
we have to comment every time after doing UI changes. and we need to check every time whether that line is commented or not.
Please Help Us.
Thanks,
Ashish.
To reproduce, rebind the grid to a data table on button click and show grid's search row.
public RadForm1()
{
InitializeComponent();
this.radGridView1.AllowSearchRow = true;
}
private void RadButton1_Click()
{
DataTable dt = this.GetData();
this.radGridView1.DataSource = dt;
}
private DataTable GetData()
{
DataTable data = new DataTable();
for (int i = 0; i < 5; i++)
{
data.Columns.Add("Column " + i, typeof(int));
data.Columns.Add("Column " + i + 1, typeof(string));
data.Columns.Add("Column " + i + 2, typeof(string));
}
for (int k = 0; k < 5000; k++)
{
object[] parameters = new object[15];
for (int i = 0; i < 15; i += 3)
{
parameters[i] = k;
parameters[i + 1] = "Text " + i;
parameters[i + 2] = "Text " + i + 1;
}
data.Rows.Add(parameters);
}
return data;
}
1. Run Telerik Theme Viewer app
2. Set Office2019Dark theme
3. Navigate to "Item Containers" tab
You will see that radTreeView does not display nodes.
Workaround:
this.radTreeView1.FullRowSelect = false;
Here is my code for localizing the Sum aggregate function. The obtained result is a partial translation:
public RadForm1()
{
PivotGridLocalizationProvider.CurrentProvider = new MyEnglishPivotGridLoclizationProvider();
InitializeComponent();
}
private void RadForm1_Load(object sender, EventArgs e)
{
this.ordersTableAdapter.Fill(this.nwindDataSet.Orders);
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Year, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Quarter, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Month, GroupComparer = new GroupNameComparer() });
this.radPivotGrid1.ColumnGroupDescriptions.Add(new PropertyGroupDescription() { PropertyName = "EmployeeID", GroupComparer = new GrandTotalComparer() });
this.radPivotGrid1.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Sum });
this.radPivotGrid1.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Count });
this.radPivotGrid1.FilterDescriptions.Add(new PropertyFilterDescription() { PropertyName = "ShipCountry", CustomName = "Country" });
this.radPivotGrid1.DataSource = this.ordersBindingSource;
}
class MyEnglishPivotGridLoclizationProvider : PivotGridLocalizationProvider
{
public override string GetLocalizedString(string id)
{
switch (id)
{
case PivotStringId.Sum:
return "Soma";
default:
return base.GetLocalizedString(id);
}
}
}
Please run the attached sample project.
Workaround: use RadTextBox instead.
To reproduce:
RadColorDialog dlg = new RadColorDialog();
dlg.ColorDialogForm.OldColor = Color.Green;
dlg.SelectedColor = Color.Red;
dlg.ShowDialog();
You will see that the OldColor (Color.Green) is not displayed in the radColorDialog.

Add several RadTreeNodes to RadTreeView and then call the Clear method of the control.
When I setup and OverloadList, the OverloadListWindow follows the cursor and can move off screen so the user can't see/read the information that is presented.
Workaround: adjust the position of the overload window when it is shown:
this.radSyntaxEditor1.SyntaxEditorElement.IntelliPrompts.OverloadListWindow.VisibleChanged+=OverloadListWindow_VisibleChanged;
private void OverloadListWindow_VisibleChanged(object sender, EventArgs e)
{
ShapedForm f = sender as ShapedForm;
Screen myScreen = Screen.FromControl(this);
Rectangle area = myScreen.WorkingArea;
if (f.Left + f.Width > area.Width)
{
f.Left = area.Width - f.Width -5;
}
}
2. Add a richtexteditor control to the form
3. Set IsSpellCheckingEnabled = true
4. Run the project, type invalid word in text box. The text is not spell-checked.
