Hello Support Team!
1. How may I change back color?
2. How may I change border color?
3. How may I change the grip image
4. How may I set location of items which I add on StatusStrip?
5. How may I locate my item to very last part of the right side of status strip? (without setting RightToLeft to yes) I need to have time at the right side of status strip, exactly like windows desktop.
Thanks.

Hi,

I need to have FilterRow to filter some columns. But I need also to filter two columns by checkboxes out of the grid (toogle checkboxes add / remove filter descriptor for this columns). That's why I have to hide Filter Box for this two columns. I did it by ViewCellFormatting event:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridFilterCellElement filterCell = e.CellElement as GridFilterCellElement;

    if (e.RowIndex == -1 && filterCell != null && filterCell.ColumnInfo.Name == "COLUMN_NAME")
    {
        filterCell.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
    }
}

It works fine, but, as mentioned in documentation, significantly slow down rendering - especially for grid with 20 columns / 100000 rows with sorting.
My question: is there any other solution?
I tried:
1) Attach / Detach this event - I tried to realize when cell with this filter box is redrawn ( because then by default it is again draw with filter box visible ). It speed up interacting with grid, but still there are situation when I see this filter box visible ( minimize Window, ColumnShooser Activate / Deactivate, DataBind, Click on filterRow ...) . Is it good way? Can I found and serve all situation in this way ?
2) Use EditorRequired / Editor Initialized instead ViewCellFormatting. But It helps only not to display filter text box - filter description and button of dropdown list still are visible.

void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
        {
            if (radGridView1.CurrentCell.ColumnInfo.Name == "COLUMN_NAME")
            {
                e.Editor = null;
                e.EditorType = null
            }
        }

3) I was think about override GridViewTextBoxColumn - to find properties responsible for displaing filterbox but I can find such thing

Could you give me some solution?

Thanks in advance!

is it possible to add some few functions in the reference tab?
I want that every time the user insert a citation, the bibliography correspond to the inserted citation will be automatically inserted below the document,

Thank you in advance

Dear Reader,
I would like to share a sample code "How to populate RadChartView using Sql, Oledb or MySql Database in WinForm (VB.NET)".
I've been searching for this sample in RadChartView documentation but can't find it anywhere. Here to anyone who is having the same problem.

MySQL Database Table Looks like:

| id |  Namess  |   Ages | Benefits |

-------------------------------------

| 1  |  John    |   16   |  51      |

-------------------------------------

| 2  |  Jake    |   22   |  60      |

-------------------------------------

| 3  |  Miley   |   30   |  15      |

-------------------------------------

| 4  |  Oggy    |   24   |  25      |

-------------------------------------

| 5  |  Piggy   |   12   |  22      |

-------------------------------------

The VB.NET Code Goes Like this:

Imports Telerik.WinControls.UI

Imports MySql.Data.MySqlClient

Imports Telerik.Charting

Public Class RadForm2

    Private Sub RadForm2_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Me.RadChartView1.Area.View.Palette = KnownPalette.Metro

        '  Me.RadChartView1.ThemeName = "TelerikMetro"

        Me.RadChartView1.AreaType = ChartAreaType.Cartesian

        Dim sarea As CartesianArea = Me.RadChartView1.GetArea(Of CartesianArea)()

        Dim sgrid As CartesianGrid = sarea.GetGrid(Of CartesianGrid)()

        sarea.ShowGrid = True

        sgrid.DrawHorizontalFills = True

        sgrid.BorderDashStyle = System.Drawing.Drawing2D.DashStyle.DashDot

        Dim connetionString2 As String

        Dim oledbCnn2 As New MySqlConnection

        Dim oledbCmd2 As New MySqlCommand

        Dim sql2 As String

        connetionString2 = ("Data Source=localhost;user id=root;database=testss;")

        sql2 = "Select * from tabll"

        oledbCnn2 = New MySqlConnection(connetionString2)

        Try

            oledbCnn2.Open()

            oledbCmd2 = New MySqlCommand(sql2, oledbCnn2)

            Dim oledbReader2 As MySqlDataReader = oledbCmd2.ExecuteReader()

            With oledbReader2

                Dim lineSeria As New LineSeries()

                RadChartView1.Series.Add(lineSeria)

                lineSeria.ValueMember = "Ages"

                lineSeria.CategoryMember = "Namess"

                lineSeria.DataSource = oledbReader2

            End With

            oledbReader2.Close()

            oledbCmd2.Dispose()

            oledbCnn2.Close()

        Catch ex As Exception

            MsgBox("Can not open connection ! ")

        End Try

        Try

            oledbCnn2.Open()

            oledbCmd2 = New MySqlCommand(sql2, oledbCnn2)

            Dim oledbReader3 As MySqlDataReader = oledbCmd2.ExecuteReader()

            With oledbReader3

                Dim lineSeria As New LineSeries()

                RadChartView1.Series.Add(lineSeria)

                lineSeria.ValueMember = "Benefits"

                lineSeria.CategoryMember = "Namess"

                lineSeria.DataSource = oledbReader3

            End With

            oledbReader3.Close()

            oledbCmd2.Dispose()

            oledbCnn2.Close()

        Catch ex As Exception

            MsgBox("Can not open connection ! ")

        End Try

    End Sub

End Class

Hope You Enjoy!

Hi!

I need to add shadow to RadProgressBar text. I've tried to add new TextPrimitive element with shadow to Children collection (it works for RadWaitingBar), but the control shows only the existing ProgressBarTextElement. Unfortunately, I can,t manage to change Shadow member for ProgressBarTextElement. 

Code changing shadow that does not work:

Hi,

I just recently upgraded my project to 2013 SP1 and it broke my solution. The designer opens the form just fine but I can't click any controls. I've attached an image of my error list. Any ideas?

EDIT: When I close the code-behind for the form and the form designer without saving the errors go away. When I open the designer, I can't click any controls. When I double click the form the code-behind opens and all the errors come back.

Thanks,
Eric.

I'm implementing an inventory program that will view, edit, add, and remove rows from an sql database using the radGridView. The program was started in visual studio 2013 ultimate and did not have this issue. When I opened it in visual studio 2012 ultimate, I suddenly get a data exception sayng "Object reference not set to an instance of an object" when trying to add the first row to the gridview. Through debugging found that it happens in between the useraddingrow event and the useraddedrow event. Once the exception happens, I can correct it by changing the datasource to another table and back again but not before it happens the first time. The exception also happens with empty event handlers (commented out)
Above are the event handlers I comment out while still getting the error.

This is how I assign the data source
The same thing is done on radiobutton checkedchanged to switch between assets and consumables table.

It seems that the data exception HAS to happen before it will let me add a row.

Attached is the error box as well. What doesn't make sense is I did not implement any exception handling that displays the exception message so the program should in theory crash when this message pops up...

Using ADO.NET entity for database access, C#, .net 4.0

I have a build from VS2013 deployed currently with roughly the same setup for the gridview that is not getting the exception.

NOTE: When I switched to VS2012, the gridview was re-added and configured to work with 2012

Hello Support Team!
Please let me know how can I change the scale transform of radListView ?
It is possible with hierarchy but how does this happen via code?
Thanks.

I have a Windows Forms application (C# .NET 3.5) which uses RadChart and RadMenu controls (version 2009.1.9.311).  I can build and run the application on the build machine (Windows 7 64-bit), but it crashes immediately when run it on any other Windows 7 64-bit PC.  I created a new test application with nothing except one RadChart and it also crashes immediately.  As soon as I click on the executable it displays the standard Windows "[program] has stopped working" error with the choice to check online for a solution or close the program.  The original application has the following details "Problem Event Name: APPCRASH; Fault Module Name: KERNELBASE.dll; Fault Module Version: 6.1.7600.16385; Exception Code: e0434f4d; Exception Offset: 000000000000aa7d; OS Version: 6.1.7600.2.0.0.256.4".  The test application only as a few details which might be useful: "Problem Event Name: CLR20r3; Problem Signature 03: 4call1179b; (PS 06 is the same); Problem Signature 07: 1; Problem Signature 08: 15; Problem Signature 09: System.IO.FileNotFoundException; OS Version: 6.1.7600.2.0.0.256.4".  I can create a similar test application with non-Telerik controls and do not get the error on other Win 7 x64 PCs.

Has anyone else experience similar issues?  Is there a solution / workaround?

Thanks,
Chris
