UI for WinForms

Hi, good day.

I have developed web applications using telerik controls with Visual Studio.

But now I'm going to develop a desktop application, so I'm going to use the Telerik controls for WinForms with Visual Studio.

I have three questions.

1. I have version 2017 of UI for ASP.NET AJAX installed, can I install a version of UI for Winforms 2022, do not create conflict?

2. What version of UI for Winforms is compatible with Visual Studio 2017?

3. In the project that I am going to carry out using Winforms, the idea is that the data is displayed as a dynamic excel table and graph. I have read the documentation and I understand that I would have to use several controls for that, I thought it would not be so laborious, is the latter correct or am I wrong?

Thank you very much for the help.

Buttons, RadioButton, CheckBox, etc

ChartView

DropDownList

same shortcut on radcontextmenu and radmenu

We use the same shortcut key in different places, where they can be in the general RadMenuItem but also on a menuitem in a RadContextMenu tied to a text box.

But, when i am focused on the text box and hit F12, it fires the radmenuitem F12 shortcut and never fires the contextmenu option. The ZIP file has the program that shows this.

Within windows using the standard menu and context menu, the context menu shortcut is fired and not the general menu shortcut. Windows seems to be treating it as you are on this field and there is a context menu with this shortcut - fire that event. Whereas Telerik seems to be looking at the general menu before the context menu.

Am i doing something wrong to get the context menu shortcut to fire and not the general menu shortcut?

Child Template Clickable but unable to insert or add data into it (Unbound Radgridview)

Hello,

I have an unbound hierarchical radgridview that has a parent template and two child templates. The master templates work fine, I can insert, type or paste data. But in the child template, I cannot add any data or rows. It remains blank. Can you tell me what I am doing wrong?

My code are below.

Sorry I am using UI Winform

Thank you in advance.

private void TestForm_Load(object sender, EventArgs e)
{
// Setup the Master Template
RadGrid.MasterTemplate.Columns.Add (new GridViewTextBoxColumn("Name"));
RadGrid.MasterTemplate.Columns.Add (new GridViewTextBoxColumn("Description"));
RadGrid.MasterTemplate.Columns.Add (new GridViewDateTimeColumn("Date"));
RadGrid.MasterTemplate.Columns.Add (new GridViewDecimalColumn ("Value"));
RadGrid.MasterTemplate.Columns.Add (new GridViewTextBoxColumn("Status"));
RadGrid.MasterTemplate.Columns.Add (new GridViewTextBoxColumn("NameCode"));
RadGrid.MasterTemplate.Columns.Add (new GridViewTextBoxColumn("Event"));

RadGrid.AllowAddNewRow = true;
RadGrid.AutoGenerateHierarchy = true;
RadGrid.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

//Setup Child Template
GridViewTemplate Childtemplate = new GridViewTemplate();
RadGrid.MasterTemplate.Templates.Add (Childtemplate );
Childtemplate.AllowAddNewRow = true;
Childtemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

Childtemplate.Columns.Add (new GridViewTextBoxColumn ("Name"));
Childtemplate.Columns.Add (new GridViewTextBoxColumn ("Description"));

//Relation between Parent & child
GridViewRelation relation = new GridViewRelation(RadGrid.MasterTemplate);
relation.ParentTemplate = RadGrid.MasterTemplate;
relation.ChildTemplate = Childtemplate;

relation.ParentColumnNames.Add("Name");
relation.ParentColumnNames.Add("Description");
relation.ParentColumnNames.Add("PtDate");

Comparing WinForms and WPF Themes

We have a WinForms application with WPF Controls embedded in it and various WPF applications. All applications use Telerik controls. I am looking into re-theming them. I can't find any information to easily compare themes. I've seen that there is an Office2019 theme in both WinForms and WPF. Are there any comparisons of them anywhere? Are there any combinations of WinForms and WPF themes that go well together without much alteration?

Validation for RadGridView being bound at Runtime

I am new at Telerik.

I would like to validate data that are in my radgridview,. If data are saved in the database they must be highlighted orange. The radgriview in my form does not have any columns before I run the application. The columns are developed programmatically and the radgridview bound at runtime.

How can I validate the columns?

I have tried the following code but it does not work.

Can you tell me what I am doing wrong?

Thank you in advance

void RadGridView_CellValidating(object sender, Telerik.WinControls.UI.CellValidatingEventArgs e)
{
var column = e.Column as GridViewDataColumn;

if (e.Row is GridViewDataRowInfo && column != null && column.Name == "Name")
{
var Value = (string)e.Value;
var Row = (GridViewDataRowInfo)e.Row;
if (string.IsNullOrEmpty((string)e.Value) || ((string)e.Value).Trim() == string.Empty)
{
e.Cancel = true;
((GridViewDataRowInfo)e.Row).ErrorText = "Validation error!";
}
else
{
((GridViewDataRowInfo)e.Row).ErrorText = string.Empty;
}
}
}

WebCam - draw a border

We would like to draw a red border around the camera stream while video is recording. I tried attaching ot the StartRecording event and modifying the UI internals:

 ((Telerik.WinControls.UI.RadWebCamElement)(radWebCam1.GetChildAt(1))).DrawBorder = true;
 ((Telerik.WinControls.UI.LightVisualElement)(radWebCam1.GetChildAt(2))).BorderBoxStyle = Telerik.WinControls.BorderBoxStyle.SingleBorder;
 ((Telerik.WinControls.UI.LightVisualElement)(radWebCam1.GetChildAt(2))).BorderWidth = 8F;
 ((Telerik.WinControls.UI.LightVisualElement)(radWebCam1.GetChildAt(2))).BorderColor = System.Drawing.Color.Red;

and it sortof works.. the border reduces size, and isn;t shown at the bottom. I have the

 radWebCam1.ControlPanelHeight = 0;

because we are adding custom controls. but when we StopRecording and I execute

((Telerik.WinControls.UI.RadWebCamElement)(radWebCam1.GetChildAt(1))).DrawBorder = false;

the border is not hidden.

The camera control is docked on teh form next to a collapsible panel, If I expand the panel, the border goes to full size. But it still doesn't hide when I set DraBorder to false.
