Hello.

I have a minor issue that happens when i have selected multiple rows and want to deselect one of them. I always have to click an extra time to accomplish this, I think it is a bug.

Thanks for any help,

Updating datatable underlying radgridview, nothing else changes.

Hi there,

I'm trying to update the dataset underneath a gridview by calling rgvRatings.Refresh()

I've noticed some strange behaviour: Firstly, the sort order within groups, as selected by the user doesn't always seem to persist after the refresh, and secondly, the "currentRow" can sometimes move to the next row? Trying to solve the combination has been ... fiddly.

I've tried using LoadLayout/SaveLayout to a string, but this collapses expanded groups. I would attempt to handle that programmatically by storing the "expanded" state, but there are "n" levels of grouping (it's basically up to the user) so this seems like a headache to achieve and test.

Is there someway I can force the grid to update the data in all of its cells without changing *anything* else about the state of the grid?

I'm using Q2 2009 SP1 btw.

Regards,

Mike

[Solved] Accessing Child Grid's HScrollBar

Hello,

I need to access the HScrollBar element of a child grid to assign an event handler to the Scroll event. I am trying to do this programmatically in the ChildViewExpanded event handler for the grid. However, every time i try to reference e.ChildViewInfo.GridViewElement.HScrollBar, the GridViewElement object is null. Any help?

Also, I have a second issue. If the HScrollBar is enabled for the grid itself, and I scroll right, then click the + sign ahead of one of the rows, it does not open the child grid. Instead, it appears to select the cell that has scrolled underneath the row header column. This is undesirable for me. Is there some way that I can prevent the cell from getting selected and instead have the Child Grid expand?

Thanks!

Jeremy

NullReferenceException in Telerik.WinControls.GridView.dll

Hello,

I've got a bit of a problem with Q2 2009 GridView. I use a child GridViewTemplate, but whenever I try to expand its row (with row.IsExpanded = true) I get a NullReferenceException at Telerik.WinControls.UI.DataGroup.get_RowCount()
at Telerik.WinControls.UI.GridViewInfo.SetViewInfoToRows(DataGroup rootGroup)
at Telerik.WinControls.UI.GridViewInfo.InitializeChildViewInfo()
at Telerik.WinControls.UI.GridViewTemplate.CreateGridViewInfo(DataGroup rootGroup, GridViewDataRowInfo parentRow)
at Telerik.WinControls.UI.GridViewDataRowInfo.SetExpanded(Boolean value)
at Telerik.WinControls.UI.GridViewRowInfo.set_IsExpanded(Boolean value).

After looking closely at what's going on I noticed that DataGroup.owner is null, and DataGroup.IsDisposed == true. I think the group gets disposed in DataAccessComponent.InitDataGrid() when I set DataMember of my ChildGridViewTemplate to null and its DataSource to a DataTable that was earlier filled with data.

After that the DataGroups never get recreated, so when I try to expand my ChildGridViewTemplate, DataGroups are still disposed (with owner set to null) and I get the exception. I also noticed that if I add new data rows to the DataTable after assigning it as DataSource than the new rows expand just fine, only the old ones throw exceptions.

So my question is, is there any way I can force the DataGrid to recreate disposed DataGroup for already existing rows ?

Regards,

Piotr Kochanowski

Vista / Windows 7 address bar

I thing every Vista / Windows 7 users know what I talking about.

[Solved] Multiple font setups for radLabel

In my application I would like to set font for all labels via themes, which work great.
Most labels sit next to controls which are set to bold.

But as I was adding more labels I noticed that some labels that I have been adding should not be bold, should be using the same font type that the rest of the labels do, but should not be set to bold.

I have tried several things, but any change to font in code is overwritten by the theme.
I have tried looking at setting conditions in the theme, but radlabelelement has nothing useful i can bank on.

Thank you,

New Visual Style Builder

Is the new style builder not in the beta release? I uninstalled the prev release, installed the beta, opened my project, went to the smarttag on a textbox, and the old editor opened...

Did I do something wrong, do we get to the new editor in a different way?

How to trap Auto-Hide event

Is there a way to get notified (via an event) when a DockWindow (with DockState=Autohide) slides out or in? I'm trying to set the focus on a textbox located in the autohide window when it is shown by mousing over the tab.

Thanks
