Hi,

I have a rad gridview windows control with two text columns and a button column. AllowAddNewRow is set to "True" for the Gridview. I have set the Text property of the button to "Apply" in RowFormatting event.There are three rows in the datasource.When the application is run, we can see the button text assigned for those three rows. But the RowFormatting event is not fired when the new row is selected, So the newly created row will have a button with blank text. Please help me on this.

Regards
Shamjith

Display a description value in propertygriditem

I have the following

class LookupItem

{

public Guid Id {get;set;}

public string Description {get;set;}

}

class SomeOtherClass

{

public int Key {get;set;}

public Guid LookupItemId {get;set;}

public string SomeProperty {get;set;}

}

Now.

The LookupItem class will be a part of a collection (or lookup list) e.g. List<LookupItem>

The SomeOtherClass is the selectedObject of the propertygrid

I have looked through the samples such as https://docs.telerik.com/devtools/winforms/knowledge-base/propertygrid-dropdown-editor

and whilst I can get the combobox or RadMultiColumnComboBox to display when editing, I need to be able to show the description value of the selected lookupitem in the propertygrid item. Currently its displaying the LookupItem.Id which is a Guid.

Any ideas? The simplest will suffice

ErrorText being set doesn't trigger the messagebox

I'm following the example of "https://docs.telerik.com/devtools/winforms/controls/gridview/editors/data-validation" to do some data validation and I'm expecting it to show an error message when the user inputs a non-validated string in the cell, like it's shown in the telerik docs, however even though I can see with the debugger that the .ErrorText property is set, a message is not shown (but e.Cancel works and the focus remains on the problematic cell)

I could call a msgbox() to show the message, but I feel that negates the purpose of setting the .ErrorText property. What am I doing wrong?

Information on the Code block:

AbsenceString = "U". SicknessString = "K". gvTimesheet's ShowCellErrors is set to TRUE on the Designer.

Private Sub gvTimesheet_CellValidating(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellValidatingEventArgs) Handles gvTimesheet.CellValidating

If e IsNot Nothing AndAlso e.Value IsNot Nothing Then

Dim column As GridViewDataColumn = TryCast(e.Column, GridViewDataColumn)

If TypeOf e.Row Is GridViewDataRowInfo AndAlso column IsNot Nothing AndAlso column.Index >= 5 Then

Dim AbsenceOrIllnessMatch As Match = Regex.Match(DirectCast(e.Value, String), "[" & AbsenceString.ToLower & AbsenceString.ToUpper & SicknessString.ToLower & SicknessString.ToUpper & "]{1}\d+")

If DirectCast(e.Value, String) <> "" AndAlso Not IsNumeric(DirectCast(e.Value, String)) AndAlso Not AbsenceOrIllnessMatch.Success Then

e.Cancel = True

DirectCast(e.Row, GridViewDataRowInfo).ErrorText = sa(

"The hours-worked values can only be numeric, with optional letters {0} or {1} preceding the numeric part to indicate absence hours or illness hours respectively."

, AbsenceString, SicknessString)

Else

DirectCast(e.Row, GridViewDataRowInfo).ErrorText = String.Empty

End If

End Sub

Excel charts - FloatingChartShape

Hi. I am trying to programatically create a spreadsheet. I can add data and graphics to the spreadsheet, but I'm not able to add a series chart. Hunting through the Telerik docs, I learned of something called a FloatingChartShape, and I think this is what I need. Unfortunately, I'm not able to get access to this class.

I'm using 2015.1.331.40 of the Telerik.Windows.Documents.Spreadsheets dll.

Can someone point me in the direction of some documentation that describes how to add a series plot to a spreadsheet.

Much thanks,

Steve

Getting the classes of custom created shapes

Hi,

I have made classes for custom shapes that i have added to my toolbox. All these classes are derived from ElementShape. My problem however is that i would like to get the type of each shape as the way i created them with my own separate classes. Once these custom shapes are dragged from the toolbox and dropped onto the diagram, they are identified as RadDiagramShape. This is a problem because i need to identify of which type each shape is, as the way that i have declared them. For example i have declared a class with an Input shape, and a class with an Output shape. I need to know from the diagram, which shape is of what type, for example is it an input shape or is it an output shape. Because my current code only tells me that it is a RadDiagramShape. This does not allow me to know whether it is an input or an output. I have attached screenshot of the problem and of my code.

Thank you,
Jacques.

RadSpinEditor with 20px height in Fluent bottom croped

I have inherited a radSpinEditor.

All my controls are 21px in height with the Fluent theme.

The bottom part (border) of the control is not shown correctly.

Attached is the rendering

My control:

public partial class IntegerTextBox : RadSpinEditor

{

public IntegerTextBox()

{

InitializeComponent();

ShowUpDownButtons = false;

Value = 0;

DecimalPlaces = 0;

TextAlignment = HorizontalAlignment.Right;

Padding = new Padding(0, 0, 3, 0);

Height = 21;

MinimumSize = new Size(0, 20);

}

Here is what was generated in the designer :

//

// numericUpDownSalYears

//

this.numericUpDownSalYears.AutoSize = false;

this.numericUpDownSalYears.Location = new System.Drawing.Point(180, 36);

this.numericUpDownSalYears.MinimumSize = new System.Drawing.Size(0, 21);

this.numericUpDownSalYears.Name = "numericUpDownSalYears";

this.numericUpDownSalYears.Padding = new System.Windows.Forms.Padding(0, 0, 3, 0);

"Convert your existing application to Telerik UI for for Winforms" does not work?

Hi,

I'm trying to Convert an existing WinForms project

I have loaded our project (WinForms) into VS2015. It has update 3 and is using .NET 4.6.2.

I have run the update wizard.

The "Convert to Telerik Controls" menu does not appear!

I am using the trial version of Telerik, if that makes any difference.

Any idea what I am doing wrong?

Thanks in advance,

Jim

RadScrollablePanel in a RadPageViewPage Windows8Theme Issue

Ok, so we have, like I said above, a scrollable panel, in a page view page and we are using Windows 8 theming in our application. So, when we set all the controls on the form to that theme, any control that is in the Scrollable panel seems to get the back color from the page view page on which the scrollable panel is located instead of the back color from the scrollable panel. This make our controls look weird. Attached is an example of what we are seeing. You will see two scrollable panels, one on the form and the other on a page view page. You can see the differences yourself.

This also happens if you use ThemeResolutionService.ApplicationThemeName = "Windows8" anywhere in our code as well
