Buonasera 

devo realizzare un pannello, contenete testo e immagini, scollabile in modo touch , cioè senza barra laterale,  attivando lo scoll con il mouse

"su e giu", sto provando con  scollablepanel  ma non so come attivare gli eventi scoll . 

e possibile avere una diritta ? magari c'e' un esempio in vb.net  ?

grazie

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

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.

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");
                relation.ParentColumnNames.Add("Value");
                relation.ParentColumnNames.Add("Status");
                relation.ParentColumnNames.Add("NameCode");
                relation.ParentColumnNames.Add("Event");

                relation.ChildColumnNames.Add ("Name");
                relation.ChildColumnNames.Add ("Description");


                RadGrid.Relations.Add(relation);

 //load data
                LoadUnboundData();

        }

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.

I would like to set columns in the Gridview as unique name. The Gridview is in unbound mode.

How can I proceed?

Editing an decimal element in a RadPropertyGrid causes the data to be rounded to 2 decimal places.

pre-edit:

editing:

post edit (no user made changes):

The desired behavior is to preserve at least original precision.

Setting the DecimalPlaces property on the BaseSpinEditorElement in the EditorInitialized event handler to 12 as suggested here: https://www.telerik.com/forums/propertygrid-rounding

caused this behavior when editing:

Suggestions?

Hello,

I am developing a hierarchical radgridview using winform. I am able to retrieve data from the database (bound data). I would like to enable users to add multiple rows in the same radgridview and then save everything to the database. I have developed another radgridview that allows users to enter data. but I want to perform these functionalities into one radgridview.

When I am trying to do that, the system says: " Rows cannot be programmatically added to the datagridview's row collection when the control is data-bound".

Can you help me with this please?

Thank you

I have a RadTextBox data bound to an Decimal field (12,9).   When the user hits the "DELETE" button on their keyboard to blank out that field's value, the value is cleared out, but the user cannot exit the control until the user enters a value of some kind (Alpha or Numeric). This is not the desired outcome that we would like.  What I would like to happen is for the bound field's value to be set to null.  Can anyone help me with code sample please.  I have tried also using a MaskedEditBox with a MaskType of  Numeric and Mask of F9, but this also gives us undesired results (0.0000000) when user clicks the DELETE button on their keyboard.

Thank you.Text
