Hi

Please Help

Language: VB.Net (VS2017)

Telerik Version: 2017.3.1017

Application Type: Windows Desktop

Looking for a solution to read the PDF file stored in SqlServer as varbinary(MAX). \

I have saved the pdf file as follows.

Private Sub Save_File()
        Dim fd As OpenFileDialog = New OpenFileDialog()
        fd.Filter = "pdf file|*.pdf"
        If fd.ShowDialog = System.Windows.Forms.DialogResult.OK Then
            Dim filebyte AsByte() = Nothing
            Dim con As SqlConnection = New SqlConnection(ConnStr)
            Dim cmd As SqlCommand = Nothing
            filebyte = File.ReadAllBytes(fd.FileName)
            cmd = New SqlCommand("Insert into tbl_Doc (LYR_Doc) Values(@pdf)", con)
            cmd.Parameters.Add("@pdf", SqlDbType.Binary).Value = filebyte
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
            Interaction.MsgBox("File saved into database", MsgBoxStyle.Information)
        EndIf
EndSub

Now I need to read this data and load in the pdfviewer.
I tried as follows. But no result.
 Dim eXactConnection As New SqlClient.SqlConnection(ConnStr)
        Dim eXactCommand As New SqlClient.SqlCommand("SELECT LYR_Doc from tbl_Doc where LYR_Name =  'Arun'", eXactConnection)
        eXactConnection.Open()
        If Not IsDBNull(eXactCommand.ExecuteScalar()) Then
            Dim Docdata As Byte() = DirectCast(eXactCommand.ExecuteScalar(), Byte())
            Using stream As New IO.MemoryStream(Docdata)
                RadPdfViewer1.LoadDocument(stream)
            End Using
        End If
 
Thanks in advance.

hello i want example code to select camera with combobox 

i use RadWebCam winforms 

Hello,

I have five buttons on a custom dockable control window. When I set the dock property for the buttons to top I want there to be padding between each button. I tried changing the buttons' margins, but that does not seem to do anything.

Thank you for your help!

The radgrid view has many different context menus it can show depending on what row you are on.

Header

Column Header

Column Filter Row (Contains, Begins With ....)

FilterRow (Type and highlights Yellow if found in Grid Results)

DataRow 

private void gvResults_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
        {

     // How to tell which row I am in so I can change if needed the context menu?

}

// This is how I can tell if it is a Data Row

GridDataCellElement dataCell = e.ContextMenuProvider as GridDataCellElement;
            if (dataCell == null)
                return;

// What about the others? 

//How can I tell  (Column Header, Column Filter, Row Filter etc.)

Hi. 

I have a class that has other classes as property in it.
I want to create a list from this class and display the list in the grid (as in the attached excel example).
Which tool should I use?

The "Incentive" class I want to use.

namespace Models.Domain
{
    public class Incentive
    {
        public string Tckn { get; set; } = string.Empty;
        public Ysys Ysys { get; set; } = new Ysys();
        public Abyob Aybob { get; set; } = new Abyob();
        public Oybyu Oybyu { get; set; } = new Oybyu();
        public Yybyu Yybyu { get; set; } = new Yybyu();
        public Yuoa Yuoa { get; set; } = new Yuoa();
        public Uidd Uidd { get; set; } = new Uidd();
    }
    public class Kanunlar 
    {
        public string ts { get; set; } = string.Empty;
        public string ios { get; set; } = "0";
    }
    public class Ysys : Kanunlar { } // 2828
    public class Abyob : Kanunlar { } //6111
    public class Oybyu : Kanunlar { } // 17103
    public class Yybyu : Kanunlar { } // 27103
    public class Yuoa : Kanunlar { } // 7316
    public class Uidd : Kanunlar { } // 3294
}

I want to create a view like this in GridView:

Can I do this with GridView or is there another tool I can use? Thank you in advance for your help.

Hello, I just have a simple question is it possible to remove the expand arrow? I just want the group to always display all the items without the option to collapse. Also, I have some items which are not in a group because the column they are grouped by is empty. Is it possible to hide the group area for these? 

Thank you

Hi,

I suspect this is not possible but thought I'd ask just in case.

Say in the syntax editor we have all the coloring going on desired. Is it possible to programmatically copy the selected text that can then be pasted into other richtexteditors keeping the formatting?

Best example of this I can think of is with Microsoft sql management studio - if you copy a query into an email or word it keeps the same coloring and formatting.
It can also be done with the standard winform richtextedit:

Clipboard.SetText(myRichTextBox.Rtf, TextDataFormat.Rtf);

Then pasting that into another richtextbox or email or even word, will maintain all the formatting.

I did try the above with GetSelectedText() but that was a no go.

Regards

Hello!

Is it possible to have a radDock with several tabbed DocumentWindows where the user is only allowed to "Float" these Documents and can ONLY dock them back on the original DocumentContainer?  Meaning the User is not allowed to Dock a floating window inside another one of these DocumentWindows?

All but one DocumentWindow is created dynamically - so I should be able to set each window as needed i'm just stuck on what those settings are!

Any help you can provide would be great!

Kindest regards,

Curtis.
