Hi...
say i have a pageview in strip mod , i wont my program to had support for english and a right to left language, i noticed that when changing the right to left property to true, the pages still at left !, and their indexes are the same.

(i.e.
right to left property set to true:

pageview looks like this
[page1]-[page2]-[page3]..................................................................................................

and they should look like this:
.................................................................................................. [page3]-[page2]-[page1]
i did search the form and found that i can change the index of the pages, and swap their location, but i'd rather have them set that way in design time. and its much easier to shift from or to right to left state if it does change the location automatically.
is that achievable or i should look to use code. thx

Group by Format String

Hi,
I have seen in other posts about problems with group by format strings. However that post was quite old, I'm using the Q3 2009 build.

When my users select a column to group by the format string that was with the column seems to be lost. i.e. if I have values £12.45 when that field is grouped it is displayed as 12.4500. I've seen an old solution which is supply the format string with the "group by" but I'm not programming the column; I just populate the grid with data and users take advantage of the group by bar.
How could I resolve this?

Duplicated child gridviews

Hello,

When using hierarchical gridview, and acceding to the child gridview with the IDE, I noticed that at first I had only one child gridview, but after clicking on OK button, I got 2, then 4 identical gridviews. And they are displaying caption tabs saying "Table".

I tried to remove them, to keep only one, but then no child gridview was kept by the designer (gridviewTemplate was lost) , and compiling became impossible.

Is this a known bug ? Is there a way to safely remove the duplicated child gridviews and keep only one ?

Thank you for any help.

Self-Reference takes too long to expand a node

I have a grid with 5 columns, the first 2 columns, ID and ParentID, are for self-reference setup and are hidden. The rest are a checkbox and 2 text columns. I set its datasource to a BindingList that has a single row and 250 "child" rows. The parent row expands fine when there is no sorting. However, as soon as I click on any of the column headers to sort, it takes more than 10 seconds to expand, and scrolling also becomes very sluggish.
I'm using the latest release, RadControls_WinForms_2010_3_10_1215_dev. Is there a trick to speed it up? Below are the code snippet and attached is a scree

Thanks,
Andy

private void Form1_Load(object sender, EventArgs e)

{

PopulateGrid();

radGridView1.Relations.AddSelfReference(radGridView1.MasterTemplate, "ID", "ParentID");

}

private void PopulateGrid()

{

BindingList<RowBindingInfo> rowList = new BindingList<RowBindingInfo>();

int rowID = -1;

for (int i = 0; i < 1; i++)

{

RowBindingInfo rowInfo = new RowBindingInfo(++rowID, -1, false, "Room " + i.ToString(), "Desc " + i.ToString());

rowList.Add(rowInfo);

int pid = rowID;

for (int j = 0; j < 250; j++)

{

RowBindingInfo childRow = new RowBindingInfo(++rowID, pid, false, string.Empty, "Desk " + j.ToString());

rowList.Add(childRow);

}

radGridView1.DataSource = rowList;

}

public class RowBindingInfo

{

public RowBindingInfo(int rid, int prid, bool incl, string r, string d)

{

ID = rid;

ParentID = prid;

Included = incl;

Room = r;

Desc = d;

}

public int ID { get; set; }

public int ParentID { get; set; }

public bool Included { get; set; }

public string Room { get; set; }

public string Desc { get; set; }

}

Thanks,

[Solved] Export to CSV

Need some help here...

I'm exporting a RadDataGrid to CSV but get the 'object reference to instance of an object' error. Every time i have a empty *.csv doc and the csvExporter.RunExport crashes...

Changing it to an Excel exporter makes it work fine.

code:

Dim exportGridView As New Telerik.WinControls.UI.RadGridView

exportGridView.DataSource = rep.GetObjectCorrespondentieGegevens(projectId)

Public Function GetObjectCorrespondentieGegevens(ByVal id As Integer) As Object Implements     ICorrespondentieRepository.GetObjectCorrespondentieGegevens

Dim model = From p In _db.tblAannemers.AsEnumerable() _

Select p.fldAannemerNaam

Return model

End Function

Private Shared Sub RunExportToCSV(ByVal fileName As String, ByRef gridView As RadGridView)

Dim csvExporter As ExportToCSV = New ExportToCSV(gridView)

'csvExporter.FileExtension = "txt"

'csvExporter.SummariesExportOption = SummariesOption.ExportAll

Try

'csvExporter.

csvExporter.SummariesExportOption = SummariesOption.DoNotExport

csvExporter.RunExport(fileName) ' this is where the exception happens :-(

Catch ex As Exception

End Try

End Sub

Order of strips to display

Hi,
I'm probably doing something wrong. But I have not find any help in documentation and in the demos.
When I prepare commandbar visually in designer, I'm able to move strips to correct order.
But how to do this in code?
I merge two commandbars together, so I add the strip to the commandCarRow, but in soe cases this second strip is displayed before the original first. And I have no clue why?

commandBarChild.Rows[0].Strips.Add(strip);

Thanks for any idea, as I said I didn't find any help in documentation or demos for that. If there is something about it, jsut point me there, please.
