Hi,

Is there a way to get version and producer metadata from imported PDF files? 

Here is how it looks in AdobeReader

Thanks in advance,

I have made an override for class GridViewDataRowInfo (called GridViewDataRowInfoPlus)

Every time a new row is created by RadGridView, I expect OnCreateRowInfo to be called, so I can return my own instance of GridViewDataRowInfoPlus.

This goes well until a user enters new data in a new row and when this row is added the grid, OnCreateRowInfo is not being called and an instance of GridViewDataRowInfo is added to the grid.

For me that is unexpected and undesirable. Maybe I am doing it wrong. In that case: What is the correct way to intercept the row-creation-process and return instances of my own type?

The version of Telerik products is requested as information where submitting a support ticket. In case one forgot the version currently installed, there is no way to find it (may be I am the only one who don't know). Usually most software provide such information in the "About" box. I found it difficult and not very useful that the "About" menu of Telerik connect to the Progress Home Page instead of displaying some useful information about the current installation (user name, version, installed components, license status, etc....). There are already many other actions (request support, online documentation, etc...) that connect to the web site. The "About" box should just be displayed within VS and provide information on the installation. Or at least you link it to the Progress Control Panel and adding a page for information I mentioned and more that user may need to know when needed.

Below is an example from VS.

Repro steps:

1. Make a datatable with a string-column with a max. length of 10 characters.
2. Add a row with a string of max. 10 characters.
3. Bind it to a RadGridView
4. Add an event-handler to DataError which will cancel the action if a data error occurs.
5. In the UI, enter data into the cell. Make it longer than 10 characters.

Expected behavior:

1. The same behavior as CellValidating.
2. De user stays inside the editor so it can modify the text.

Observed behavior:

1. The editor is closed, the new text is not displayed.

Report steps:

1. Make a datatable with a string-column with a max. length of 10 characters.
2. Will the datatable with some data.
3. Bind it to a RadGridView
4. In Excel (or another applicatie) create a now table with some strings, this time longer that 10 characters.
5. Paste this data from Excel to the RadGridView

Expected behavior:

1. The strings that are to long will either cause an exception or they are truncated.

Observed behavior:

1. The string with the value that is to long is skipped during pasting.

Extra detail:

In the method MasterGridViewTemplate.PasteDataToRow the next piece is code is located:

if (CurrentView.ViewTemplate.Columns[columnIndex].DataType == typeof(string))
{
    if (column is GridViewTextBoxColumn viewTextBoxColumn && viewTextBoxColumn.MaxLength > 0 && rowData[rowIndex].Length > viewTextBoxColumn.MaxLength)
        obj = rowData[rowIndex].Substring(0, viewTextBoxColumn.MaxLength);
}

When I create a new form-class, which derives from RadFrom, and I override the method OnLoad, then OnLoad is called during construction. This should never happen!

As Microsoft states: "The OnLoad method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class."

See: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.form.onload?view=windowsdesktop-6.0 

The OnLoad method can be used to load controls with data. But these controls are not even initialized, because the method InitializeComponent has not been called yet.

Hi,

An HTTP Request returns me an error in HTML format. Please see img001. This image was capture in debug mode in Visual Studio.

When I want to show a MessageBox or a Label with this HTML, appears like in img002.

Thank you!

The HTML text is:

• I'm using Visual Studio 2022 Community. Running as Admin.
• I've installed the latest Winforms (Telerik_UI_For_WinForms_2022_1_222_Dev.msi)
• I open Visual Studio and select to create a Word-like project.
• The files are all created
• One nuget reference is present under Dependencies/Packages, but shows as unresolved (UI.for.WinForms.AllControls.Net60 (2022.1.222.0))
• Using the NuGet Package Manager, there is no Telerik package source present.

So, at this point this seems to be a possible bug. The template project did not setup correctly. I have literally done nothing other than download and install Telerik WinForms today and then try to create this project. This _should_ work or give me instructions of further setup that I have to do manually.

I did try a couple other things, but also failed to get things working.

• I tried to setup the Telerik Package Source as https://nuget.telerik.com/v3/index.json
• I was able to see various WinForms packages in the Package Manager, includes the one registered in the project. But VS won't update the project to resolve the package.
  
• I uninstalled the nuget package to try reinstalling it, but the re-install failed with the following messages

followed by many more "NotFound" messages.

The following code to make the headers bold in a RadGridView.  After upgrading to different 2022 versions from 2021, this code causes a Parameter is not valid error in ((System.ComponentModel.ISupportInitialize)(this.RadGridView1.MasterTemplate)).EndInit();

If I comment out the code and run then there is no error generated.

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)

Eery time I use the GridView, I have to remember to un-select the last item in the list.

This is almost always to wrong thing to be selected - so why select it by default?

..and the way to swith this 'feaure' off isn't obvious - I always have to look it up....RadGridView1.CurrentRow = Nothing

System.Reflection.TargetInvocationException:“Exception has been thrown by the target of an invocation.”

XamlParseException: “类型“Telerik.WinForms.Documents.Model.RadDocument”不具有内容属性。指定要设置的属性的名称，或者在该类型上添加 ContentPropertyAttribute 或 TypeConverterAttribute。”，行号为“5”，行位置为“4”。

Hi. it was great to see the option "ImageOnly", for columns of small width, where only the image is placed in the header, and the "HederText" property was set, for the correct display of the grouping field

GridViewDataColumn column;

column.HeaderText = "Счет";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

GridViewDataColumn column;

column.HeaderText = "";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

it’s impossible to choose one thing, either an ugly header, or a grouping without a description

How to reproduce: check the attached project:

Workaround: when the form is opened in the designer make sure that all pages are made visible at least ones so the controls are initialized, before attempting to access collection editors via properties window

This behavior occurs when there is no Telerik package installed in the project but the toolbox loads the controls using the version available in C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

Then drag a gauge form the toolbox and drop it into the form:

To reproduce:

        public RadForm1()
        {
            InitializeComponent();

            string txt = "what follows is test characters (some of) which should cause error:  เปลี่ยน UPS ที่ห้อง Truck scale เนื่องจากเมื่อวันพฤหัสที่ 13 มีการออฟเบรกเกอร์ที่ ฺฺB/H แต่ว่า เครื่องคอมพิวเตอร์ที่ T/S ดับ ตัว UPS ไม่ทำงาน ทำให้ข้อมูลขณะนั้นหายไป   ";
            this.label1.Text = txt; // No error

            Font font = this.label1.Font;// new Font("Segoe UI", 9.5f, FontStyle.Regular);
            this.radLabel1.Font = font;
            this.radLabel1.Text = txt; //GDI error
        }

Workaround: 

this.radLabel1.UseCompatibleTextRendering = false;

Hi, when I select a date in the calendar and want to display it in a box, it also displays the base date each time I select a date.

First select the correct date but by selecting the same date show RangMinDate

my code is

private void radCalendar1_SelectionChanged(object sender, EventArgs e)
        {



            label1.Text = radCalendar1.SelectedDate.ToString();

        }

Hi,

I have a question regarding RadGridView. When I edit a cell in GridView and then click on a button (outside of gridview) immediately (i.e I don't click on another cell to exit edit mode), the Gridview is still edit mode. Please refer to the short video named "Without Using EndEdit()" to easily understand my point here.

In order to exit the edit mode, I try the following code:

    Private Sub CustomGridView_LostFocus(sender As Object, e As EventArgs) Handles Me.LostFocus
        Me.EndEdit()
    End Sub

With this code, the gridview does exit the edit mode when I click on another button. But there is a problem with this method is that afterwards, I cannot edit the cell anymore.  Please refer to the short video named "Using EndEdit()" to better understand the problem.

So my question here is, is there any way that I can exit edit mode when clicking on another button right after editing a cell?

Thank you for your help.

Best regards,

Tran

To reproduce: please open the attached sample project and follow the steps illustrated in the attached gif file.

Workaround: 
1. You still can scroll while dragging a row by using the mouse wheel.

2. Use the grid in unbound mode and set the AllowRowReorder property to true instead of using a custom RadDragDropService.

3. Use a custom drag and drop service:

public class CustomDragDropService : RadGridViewDragDropService
{
    public CustomDragDropService(RadGridViewElement gridViewElement) : base(gridViewElement)
    {
    }

    public override string Name
    {
        get
        {
            return typeof(RadGridViewDragDropService).Name;
        }
    }

    protected override void HandleMouseMove(System.Drawing.Point mousePosition)
    {
        base.HandleMouseMove(mousePosition);
        System.Drawing.Point location = this.GridViewElement.ElementTree.Control.PointToClient(Control.MousePosition);
        GridTableElement tableElement = this.GetTableElementAtPoint(location);

        ISupportDrag supportDrag = this.Context as ISupportDrag;
        object dataContext = supportDrag.GetDataContext();

        if (this.AllowAutoScrollRowsWhileDragging && dataContext == null)
        {
            ScrollRows(tableElement, location);
        }
    }

    private void ScrollRows(GridTableElement tableElement, System.Drawing.Point location)
    {
        ScrollableRowsContainerElement scrollableRows = tableElement.ViewElement.ScrollableRows;
        RadScrollBarElement vScrollbar = GetVeritcalScrollbar(tableElement);
        System.Drawing.Rectangle containerBounds = scrollableRows.ControlBoundingRectangle;

        if (containerBounds.Contains(location) ||
            location.X < containerBounds.X ||
            location.X > containerBounds.Right)
        {
            return;
        }

        int delta = 0;

        if (location.Y > containerBounds.Bottom)
        {
            delta = location.Y - containerBounds.Bottom;
        }
        else if (location.Y < containerBounds.Y)
        {
            delta = location.Y - containerBounds.Y;
        }

        if (delta != 0 && vScrollbar.Visibility == ElementVisibility.Visible)
        {
            vScrollbar.Value = ClampValue(vScrollbar.Value + delta,
                vScrollbar.Minimum,
                vScrollbar.Maximum - vScrollbar.LargeChange + 1);
        }
    }

    private int ClampValue(int value, int minimum, int maximum)
    {
        if (value < minimum)
        {
            return minimum;
        }
        if (maximum > 0 && value > maximum)
        {
            return maximum;
        }
        return value;
    }

    private RadScrollBarElement GetVeritcalScrollbar(GridTableElement tableElement)
    {
        if (GridViewElement.UseScrollbarsInHierarchy)
        {
            return tableElement.VScrollBar;
        }
        return GridViewElement.TableElement.VScrollBar;
    }
}

public RadForm1()
{
    InitializeComponent();
    CustomDragDropService customService = new CustomDragDropService(radGridView1.GridViewElement);
    radGridView1.GridViewElement.RegisterService(customService);
}
