Grid Not Updating unless Scrolled or Sorted

Hello,

Has anyone seen the following behavior:

We have a grid (2010Q3), there is a column with decimal numbers, we update the data in the column in code but the grid won't show the new numbers unless you scroll up and down, or sort. We tried calling .Refresh or .Update on the grid but it did not help...

Any ideas?

See attached screenshot for details.

Thanks.

Theme Issues

Hi

I am trying out the different themes on the PageView control in "Outlook" viewmode and at design time it only allows me to select the Office 2010 theme and doesn't allow me to select any other theme (that I have tried) .

If I programatically set the theme it works but it doesn't have the nice "hover over" effects. This applies to the Office2007Black and Office2007Silver. The other themes I test work fine when I programatically set the theme name.

Am I doing something wrong or does the PageView control not support these themes ?

Regards

Paul.

Copying RowFormatting in GridView with Hierarchy

Hello,

I'm using the hierarchical gridview with an object-relational datasource (programatically).
I'm displaying a list of order Items which have the property "ParentOrderItem".
Every item with a parent order item is displayed as a child row. Everything works fine.

What I want to do is copying the formatting of the gridview (done via Property Bilder - saying which columns to be shown, which header texts, ...) to the format of the child rows, since they alway show the same entities. This would help me doing the same work only once.

Here is the code where I set up my hierarchy:

//orderItemsgrid.DataSource is "theOrder.SD_Order_Items"



GridViewTemplate template = new GridViewTemplate();

template.DataSource = theOrder.SD_OrderItems;

orderItems_grid.MasterTemplate.Templates.Add(template);

GridViewRelation relation = new GridViewRelation(orderItems_grid.MasterTemplate);

relation.ChildTemplate = template;

relation.RelationName = "OrderItemOrderItem";

relation.ParentColumnNames.Add("OrderItemID");

relation.ChildColumnNames.Add("ParentOrderItem");

orderItems_grid.Relations.Add(relation);

Thanks for any help on this matter.

How do I remove the hierarchy child border?

Hi,

I'm using the 2010 Q3 release and I am trying to remove the thick border around a hierarchy child grid.
I'm not trying to change the size, just remove the thick border.
I've read several threads, but none work or answer my question. Most threads assume there is a ChildTableElement.TableBodyElement
but there is no such object.
Now how do I get rid of this thick border, without having to define a Theme?

Best regards,

Henri

How to prevent scroll bars for a treeview in an automated manner?

I have a treeview whose initial size is 500 x 450 (width x height).
I would like the tree view rectangle to autosize as nodes are expanded/contracted.
Even though I set autosize = true, and give it a minsize > (0,0) and maxsize > minSize, the autosizing does not happen.

Is there any trick to autosizing a treeview?
I am using Q1 2008 SP1.

Thanks
Sunil

Issue Trying To Run 3-Level Hierarchy

Hi I am trying to run a routine that is to show three levels of hierarchy thus:-

Main Level RadGridView ('rgvInletDetails')       CylinderID, some fields.....        Bound to 'Inlet' Table
Second Level Template   ('CylTemplate')          CylinderID, some fields ........    Bound to 'Cylinders' table
Third Level Template     ('CylGasTemplate')      CylinderID, some fields .......     Bound to 'CylinderGas' table

My routine to accomplish this is as follows:-
======================================================================

Dim CylRelation                 As GridViewRelation
Dim CylGasRelation          As GridViewRelation
Dim CylTemplate               As GridViewTemplate
Dim CylGasTemplate        As GridViewTemplate

'setup the master template
rgvInletDetails.MasterTemplate.Columns.Clear
rgvInletDetails.MasterTemplate.AddNewRowPosition = SystemRowPosition.Top
rgvInletDetails.MasterTemplate.AllowAddNewRow = True
PopInletDetails(rgvInletDetails) ' Binding Source for rgvInletDetails.DataSource = 'Inlet' table

'setup the Cylinder child template (Level 2)
CylTemplate                                          = New GridViewTemplate()
CylTemplate.Caption                           = "Cylinders"
CylTemplate.AllowAddNewRow      = True
PopCylinderData(CylTemplate)                                                                'setup BindingSource for level 2 with 'Cylinder' table
rgvInletDetails.MasterTemplate.Templates.Add(CylTemplate)         ' add 2nd Level Template to MasterTemplates

'setup the CylinderGas child template (Level 3)
CylGasTemplate                                     = New GridViewTemplate()
CylGasTemplate.Caption                      = "Cylinder Gas"
CylGasTemplate.AllowAddNewRow = True
PopCylinderGas(CylGasTemplate)                                                         'setup BindingSource for level 3 with 'CylinderGas' table
rgvInletDetails.MasterTemplate.Templates.Add(CylGasTemplate)  ' add 3rd Level Template to MasterTemplates

'create the Cylinder relation
Cylrelation                                            = New GridViewRelation(rgvInletDetails.MasterTemplate)
CylRelation.ParentTemplate              = rgvInletDetails.MasterTemplate
Cylrelation.ChildTemplate                 = CylTemplate
Cylrelation.RelationName                  = "Cylinders"
Cylrelation.ParentColumnNames.Add("CylinderID")
Cylrelation.ChildColumnNames.Add("CylinderID")
rgvInletDetails.Relations.Add(Cylrelation)

'create the CylinderGas relation
CylGasRelation                                   = New GridViewRelation(rgvInletDetails.MasterTemplate)
CylGasRelation.ParentTemplate      = CylTemplate
CylGasRelation.ChildTemplate        = CylGasTemplate
CylGasRelation.RelationName         = "CylinderGas"
CylGasRelation.ParentColumnNames.Add("CylinderID")
CylGasRelation.ChildColumnNames.Add("CylinderID")
rgvInletDetails.Relations.Add(CylGasRelation)

================================================================

Ok - all done. Now when I run this the main grid is displayed correctly with a '+' showing there are records for the 2nd level. However, when I click on
that '+' button then I get this message:-

(see attachment 'errordisplay.jpg' )

Actually an example of a three level hierarchy would be invaluable as it isn't immediately clear on the set up for this arrangement. This requirement above is further complicated by the fact that both Relations have to specify the same field name and I was worried in case the grid thought that it might have to produce two Level 2 grids rather than a Level 2 and a Level 3. As it is I probably have this incorrectly specified. But it would be really nice if an example of both arrangements could be provided.

Many thanks for taking the time to read this and if there are any other details I can provide please ask.
I am using this in a VB.Net 2.0 VS2008 IDE for Windows Forms and the RadgridView is from the 2010.3.10.1109 release.

Does anyone in Telerik know what the message "measure override returned positive infinity" actually means? Can't find any trace of it on the Internet.

SpinEditor sound when Enter key is hit

Hello,

I attempted to use RadSpinEditor to edit an integer value. Everything was fine with one exception: when Enter key is hit by the user (at the end, to announce the completion of the editing process), an annoying sound (beep) is heared. There is a way to get rid of this sound?

Auto scroll when selecting rows with mouse

Hi,

is it possible to auto scroll GridView when selecting data with mouse?
When I click on first row and first cell, hold the mouse button and drag with mouse to select more rows, I need that GridView auto scrolls to show me rows, which did not fit in a page.
Because now I cannot select rows which are not visible.
