If you have two RadGridView controls and you want to export both of the grids to a common file on two different sheets, it is suitable to use FileExportMode.NewSheetInExistingFile. However, when using the export overload to a stream doesn't respect the ExportMode.

Workaround: use exporting to a file:

            string exportFile = @"..\..\exportedData.xlsx";
            GridViewSpreadStreamExport spreadStreamExport = new GridViewSpreadStreamExport(this.radGridView1);
            spreadStreamExport.FileExportMode = FileExportMode.NewSheetInExistingFile;
            spreadStreamExport.ExportVisualSettings = false;
            spreadStreamExport.RunExport(exportFile, new SpreadStreamExportRenderer());

Hi there,

We have recently found a bug on both the RadDocument and Rad Rich Text Editor. Created a RTF document via the RadRichText Editor. The RTF document contains a table. When the document is saved and loaded from the same form, it is displaying correctly, however when loaded from a different form, it seems to have shrunk and lost the column width, thus having long and skinny columns.

We have set the fixed column width on the table, however this did not seem to solve the issue.

I have attached two screenshots for reference. One with the correct looking table, and one with the long and skinny columns.

Is there a workaround, or is this a known bug?

Correct table:

Long and skinny columns:

Currently on Telerik Winforms version 2018.3.1016.40

Kind regards,

Hi Telerik Team,

I tried to copy and past the sourcecode from one of your demo applications (not using the copy source button!). 

Unfortunaly every time I want to copy the "<" character it skips the rest of the line.

The problem occurs on different code examples.

I know there is a "Copy source" button but sometimes you just want to copy a small part.

A screenshot of an example is attached.

Hi everybody

I m try use the class CustomDragandDrop on radtreeview but i have a issue, 

if i use the next example, i dont have any problem:

   protected void BindRadTreeView()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Id", typeof(string));
            dt.Columns.Add("Title", typeof(string));
            dt.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string childId = string.Empty;
            for (int i = 0; i < 2; i++)
            {
                parentId = Guid.NewGuid().ToString();
                dt.Rows.Add(parentId, "Node" + i, null);
                for (int j = 0; j < 5; j++)
                {
                    childId = Guid.NewGuid().ToString();
                    dt.Rows.Add(childId, "SubNode" + i + "." + j, parentId);
                }
            }

            this.radTreeView1.ChildMember = "Id";
            this.radTreeView1.ParentMember = "ParentId";
            this.radTreeView1.DisplayMember = "Title";
            this.radTreeView1.DataSource = dt;


        }

i can drag and drop correctly

but the problem is when i binding the Radtreeview

    protected void llenatreeview1() {

            dtTablas = dat.consultaBD();

            DataTable dt = new DataTable();
            dtCopi.Columns.Add("Id", typeof(string));
            dtCopi.Columns.Add("Title", typeof(string));
            dtCopi.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string Id = string.Empty;
            string title = string.Empty;
            foreach (DataRow row in dtTablas.Rows)
            {
                parentId = row["ParentId"].ToString();     

                Id = row["Id"].ToString();
                title = row["Title"].ToString();

                if (parentId == "")
                    dt.Rows.Add(Id, title, null);
                else
                    dt.Rows.Add(Id, title, parentId);
            }

            radTreeView2.ChildMember = "Id";
            radTreeView2.ParentMember = "ParentId";
            radTreeView2.DisplayMember = "Title";
            radTreeView2.DataSource = dt;
        }

first is freeze and then appears the error.

when i drag and drop appears then next error:

System.StackOverflowException

what am I doing wrong please your help. thanks

Just add an image in the editor and try to click on it

The problem, as described in the video, is that the thumb does not 'snap' to the point touched and then follow the touch as it is dragged. It is therefore difficult at times to actually 'grab' hold of the thumb unless you touch the screen in exactly the right point.

Changing the 'SnapToTicks' property purely makes the movement smoother once it is grabbed.

Dear Support,

I want to use the new feature - Support for SVG.

Then I have to load the file with RadSvgImage.FromFile().

I get the following exception:

System.Xml.XmlException: 'External DTD subset cannot be resolved - public ID =' - // W3C // DTD SVG 1.1 // EN ', system ID =' http://www.w3.org/Graphics/ SVG / 1.1 / DTD / svg11.dtd '.'

(Translated from German)

Problem is line 2, where the DTD is given.

Is there a way to tell XmlSerializer to ignore the validation?

An error occur when i used .Import method on large .pdf files (> 1000 ko) with an Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider object.

Message is:

"Impossible d'effectuer un cast d'un objet de type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfDictionary' en type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'." 

There is no bug for smaller pdf files. 

Thank you

Hi,

I have menu problem:

When the Backstage Button Item is clicked and you don't release a left mouse button click but instead mouse is dragged to the right of the form, Backstage Button Item stay selected and can only be returned to default state if you click on it again else its stays blue and locked.

Picture 1.

Left click, hold and drag to the right. This state can be done to all buttons see Picture 2. Focus on "MouseDown" Event is not working.

Picture 2.

My question is can this behavior be prevented ?

Thanks in advance !

When the RadMap.ShowSearchBar property is set to true and the BingRestMapProvider is used, it would be nice to have autocomplete suggestion while the user is typing:

https://docs.microsoft.com/en-us/bingmaps/rest-services/autosuggest

1. Set the DPI of your main monitor to 150% and the DPI of your secondary monitor to 100%.

2. Start your main form containing RadDataEntry on your secondary monitor.

You will see that that hosted controls inside RadDataEntry are not scaled correctly.

Workaround:

Start your main form on your secondary monitor inside OnShown event.

protected override void OnShown(EventArgs e)
{
    base.OnShown(e);

    this.Location = new Point(-800, 100);
}

1. Set HDPI on your monitor (for example 150%)

2. Set RadDataEntry data source in RunTime

You will see that RadDataEntry hosted controls are not scaled correctly.

Note that there is a related problem if the data source is set in design time. Controls themselves will be scaled correctly, however, text box hosted control's High will not be scaled correctly.

Workaround:
You can subscribe to ItemInitializing event before you set the DataSource and proceed by scaling RadDataEntry hosted controls manually as shown in the following code snipped.

private void radButton1_Click(object sender, EventArgs e)
{
    this.radDataEntry1.ItemInitializing += RadDataEntry1_ItemInitializing;
    this.radDataEntry1.ItemDefaultSize = new Size(200, 26);

    radDataEntry1.DataSource = new Employee
    {
        FirstName = "Sarah",
        LastName = "Blake",
        Occupation = "Supplied Manager",
        StartingDate = new DateTime(2005, 04, 12),
        IsMarried = true,
        Salary = 3500,
        Gender = Gender.Female
    };         
}

private void RadDataEntry1_ItemInitializing(object sender, ItemInitializingEventArgs e)
{
    if (this.radDataEntry1.RootElement.DpiScaleFactor.Width != 1)
    {
        foreach (Control control in e.Panel.Controls)
        {
            control.Scale(this.radDataEntry1.RootElement.DpiScaleFactor);
        }
    }
}

Hi Peggy,

It sounds a bit too complicated for the pre sales engineer. Can you please kindly let me know the license holder email and I will issue a support ticket on his Telerik account so that the developing team can get involved.

Hi Peter,

我們在跟一個客戶討論續約問題，因為如果不續約，當下的版本是否可以一直沿用，因為這套軟體升級不會刪除舊檔案，導致很多問題出來。

因為客戶編輯好專案,也進行發行動作,但是安裝到電腦會發生錯誤,請問要在其他台電腦執行客戶的安裝該如何執行.

請回復技術問題.

軟體下進行模擬可以正常運行.

執行發行後的安裝檔

無法安裝.

附件有錯誤檔案.

Please refer to the following code snippet and follow the steps in the attached gif file:

        Dim dt As New DataTable
        dt.Columns.Add("Id", GetType(Integer))
        dt.Columns.Add("Name", GetType(String))
        For index = 1 To 10
            dt.Rows.Add(index, "Data" & index & Guid.NewGuid().ToString())
        Next
        Me.RadMultiColumnComboBox1.DataSource = dt
        Me.RadMultiColumnComboBox1.DisplayMember = "Name"
        Me.RadMultiColumnComboBox1.ValueMember = "Id"
        Me.RadMultiColumnComboBox1.AutoSizeDropDownToBestFit = True

Workaround: 

AddHandler Me.RadMultiColumnComboBox1.DropDownOpened, AddressOf RadMultiColumnComboBox_DropDownOpened

    Private Sub RadMultiColumnComboBox_DropDownOpened(sender As Object, e As EventArgs)
        Me.RadMultiColumnComboBox1.EditorControl.HorizontalScrollState = ScrollState.AutoHide
    End Sub

Hi,

• Open the VisualStudio2012Light.tssp using UI WinForms Visual Style Builder.
• Select on RadButtonElement and Element state is ButtonFill. Double click on NormalFill repository, below is the error (attached the snapshot) -

object reference not set to an instance of an object

Questions:

• How to resolve this issue.
• How to trace log if any.

Regards,

Rajesh

Please refer to the attached sample project and gif file. The ShouldCheckDataRows property of the column is disabled. Hence, the developer will manage the toggle state of the data cells.

There are two problems here:

1. In the HeaderCellToggleStateChanged event we toggle all data rows in correspondence with the header checkbox. Once a data cell value is changed, we set the GridViewCheckBoxColumn.Checked property to Off. However, it is not respected and the header checkbox still remains toggle.

2. Once you scroll the columns horizontally, the header checkbox synchronizes with the value of the GridViewCheckBoxColumn.Checked property. However, all of a sudden the HeaderCellToggleStateChanged event is toggled again even though we didn't clicked the checkbox in the header at all. This will make all data cells unchecked due to the code in the HeaderCellToggleStateChanged event.

You cannot implement custom logic that requires hiding a DragOverNode hint window. 

Workaround:

public class MyTreeViewDragDropService : TreeViewDragDropService
{
    public MyTreeViewDragDropService(RadTreeViewElement owner)
        : base(owner)
    {
    }

    public void HideHintWindow()
    {
        this.HintWindow.Hide();
    }
}

private void RadTreeView1_DragOverNode(object sender, RadTreeViewDragCancelEventArgs e)
{
    ((MyTreeViewDragDropService)this.radTreeView1.TreeViewElement.DragDropService).HideHintWindow();
}
