Hello

I want to format the thousand separators in a PIVOTVIEW

My Code :

                e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
                e.CellElement.ForeColor = Color.LightGreen;
                e.CellElement.Alignment = ContentAlignment.MiddleRight;
                //e.CellElement.Text = String.Format("{0:N3}");

the ForeColor is working,

but aligment right does not work ( see screen below)

and string format gives error

Is it possible to serialize a spreadsheet?

My app has a way that it can save text-only data (but not .xls or other files) and I'd like to save the current contents of a RadSpreadsheet control, so I can open it again later. This would let my users add/remove columns, add/remove charts etc.

Is there an easy way to do this?

Hi all,

When inserting a row everything goes okay.
But when I delete that same row again using the radgridview contextmenu option Delete Row

Then the debugger shows the following error massage:
'System.Data.DBConcurrencyException: 'Concurrency violation: the DeleteCommand affected 0 of the expected 1 records.''

My code is below.

What am I doing wrong?

Chris.

 public partial class mainForm : Form
    {

        public static OleDbConnection con3 = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source = " + Application.StartupPath + "\\parts.accdb");
        public static DataTable dt = new DataTable();
        public OleDbDataAdapter adapter;
        public OleDbCommandBuilder commandbuider;
        public mainForm()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            string SQL = "SELECT * from supplier";
            adapter = new OleDbDataAdapter(SQL, con3);
            commandbuider = new OleDbCommandBuilder(adapter);

            adapter.Fill(dt);

            PartsGrid.DataSource = dt;

            PartsGrid.RowsChanged  += new GridViewCollectionChangedEventHandler(PartsGrid_Update);

        }

        private void PartsGrid_Update(object sender, GridViewCollectionChangedEventArgs e)
        {
            if (adapter.Update(dt) > 0)
            {
                MessageBox.Show("done");
            }
        }
    }

I use Telerik.WinControls.UI.RadChartView

I try to use RadChartView for show graphical lines. I have prepared series of ScatterLineSeries and upload its to RadChartView.Series. First page can show successfully. Unfortunately I can not show next page. I setting break after uploading data to RadChartView. Visual Studio mark by red color any changes (differences) in RadChartView properties and data.

I can see only small changes in data value and no more.

So, data for showing on second page is similar to data on the first page. However RadChartView show absolutely empty page.

Can anybody advice for me, what checklist I can pass to understand why second page is clear blank page?

Easy to reproduce.

In function that's located in a RadForm

void DoSomething(Form form)
{
  MessageBox.Show(form.FormBorderStyle.ToString());

  MessageBox.Show(this.FormBorderStyle.ToString());

}

It returns "none" if form is a RadForm. The 2nd messagebox shows "sizeable" as this is a radform.

I wondered why it's doing this if a RadForm is a descendent.

Hello,
In RadGridView, I set the column to GridViewDateTimeColumn.
I want to change the date display format to short.
Code below.

Public Class RadForm5
    Private Sub RadForm5_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim listTest As New List(Of TestDate)
        listTest.Add(New TestDate With {.Name = "John", .DateStart = New Date(2022, 5, 1)})
        listTest.Add(New TestDate With {.Name = "Arya", .DateStart = New Date(2022, 5, 2)})
        listTest.Add(New TestDate With {.Name = "Brandon", .DateStart = New Date(2022, 5, 3)})
        listTest.Add(New TestDate With {.Name = "Catelyn", .DateStart = New Date(2022, 5, 4)})

        For Each col In RadGridView1.Columns
            If col.Name = "colDate" Then
                col.FieldName = "DateStart"
                Dim colDate As GridViewDateTimeColumn = TryCast(col, GridViewDateTimeColumn)
                colDate.Format = DateTimePickerFormat.Short
            End If
        Next

        RadGridView1.DataSource = listTest
    End Sub
End Class

Public Class TestDate
    Public Property Name As String
    Public Property DateStart As Date
    Public Sub New()

    End Sub
End Class

Unfortunately, setting the display format does not work properly.
I have to add more fields in object every time

   Public ReadOnly Property DateStartStr As String
        Get
            Return DateStart.ToShortDateString
        End Get
    End Property

And

col.FieldName = "DateStartStr"

Is there another way to do this?

Regards

Jack

Hello all.

Does anyone know how to fix this?  Please see image #1

That's just a small section of the Toolbox - every Telerik Control has multiple entries.

Each duplicate points to the same Library.

Each tool has the identical Version as its Duplicate.

I have uninstalled, reinstalled a few times.  Does not fix it.

Telerik Toolbox Configurator does not fix it.

Help/Advice would be appreciated!

Thanks all :)

So, this is weird and I'm sure my fault, but I'm having a problem.

This is an unbound grid.

I have 26 rows that should be added to the grid.  So I iterate through all of the rows to add them to the grid, all appears well.  Checking the row count, there are 26 rows. But when viewing the grid, there are only 24 rows displayed.  The last two rows that should be there, do not appear.

However, if I enable the default row filtering and filter on one of the missing rows, I can find them and they are displayed as expected.

Pagination is disabled (I enabled it just to see if they were appearing on the next page, they are not).

There are no filters applied to this grid (except as the above test with the default filter row displayed)

I have no idea what I'm doing wrong, so any help to point me in the right direction would be great.

Again, to be clear, its not a data problem, the rows are there in the grid.  Its a display problem.

Thanks for any suggestions!
