Hello,
I have a grid with certain fields that are not editable depending on the value of other fields on that row. The best way I came up with to handle this was to wire up the CellBeginEdit event, and if the field is not allowed to be edited, then cancel the event.
I have a grid with certain fields that are not editable depending on the value of other fields on that row. The best way I came up with to handle this was to wire up the CellBeginEdit event, and if the field is not allowed to be edited, then cancel the event.
| Private Sub rgvLines_CellBeginEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles rgvLines.CellBeginEdit |
| Select Case e.ColumnIndex |
| Case rgvLines.Columns("MFG_ENTITY_ID").Index |
| Dim lineCategoryTypeId As Integer |
| Dim lineCategoryShortName As String = Nothing |
| 'Get the Line Category short name |
| lineCategoryTypeId = CType(rgvLines.CurrentRow.Cells("LINE_CATEGORY_TYPE_ID").Value, Integer) |
| lineCategoryShortName = GlobalMethods.GetTypeDefShortNameForTypeID(lineCategoryTypeId) |
| If lineCategoryShortName = AppDefs.LineCategoryShortName.Group |
| e.Cancel = True |
| End if |
| End Select |
| End Sub |
This all works fine but the problem that I am having is that if the user has tabbed into this cell, then focus still stays with the cell that editing was cancelled for. The default behavior is for tabbing to skip over read-only columns. So once I cancel the CellBeginEdit event, how can I get to the next editable cell? Is it possible to simulate the tab key press programmatically?
Thanks,
Sean

When hiding or showing a tool window, there is a noticeable flicker on the rest of the controls in the rad dock. Setting the AutoHideAnimateMode to None seems to help a little but I can still see the flicker.
Setup:
I have two docking windows with user controls pre-loaded. I have four tool windows with user controls dynamically loaded.
Observations:
If I remove the pre-loaded user controls from the docking windows, there is no flicker. If I dynamically load the user controls into the docking window, the flicker occurs.
Thoughts?

When loading the RadDock from a previously saved XML file, there is a noticeable paint issue. The first thing drawn on screen is one of the docked windows, then about a second or two after that, the rest of the dock loads. Simply turning off the loading from XML fixes the issue. I thought it might be a problem with the RadDock's active window being incorrectly set, but after reading this post (http://www.telerik.com/community/forums/winforms/dock/autohide-doesn-t-seem-to-work-for-right-docked-toolwindows.aspx) and explicitly setting the active window, I don't think active window is the issue because the paint problem persists.
Thoughts?

Hi,
In my form at some event I am adding a RadDateTimePickerElement to a cell of a gridview. The RadDateTimePickerElement shows date picker. However my requirement is such that I want to show only a timepicker and want to select a specific time of day. But currently it allows me to select days and not time. I want tp select time of day.

we have a licensed version of RadControls for WinForms 2009.2.9.729
Currently we have an Client Server application using telerik controls that is built and deployed using the standard setup project within VS2005, this all works grand when installed on XP operating system.
but the application wont run on Win Server 2003. the app wont run any forms that contain telerik controls, and just wondering is it not possible to run on Win Server 2003?
also, what about Vista
Many thanks.

Though it's not a big deal, I'd like to remind you that the documentation of RadTreeView still refers to AfterSelect event, which seems to be marked with an Obsolete attribute.
Please check out the topic "Responding to Mouse Click" and "Responding to Selected Nodes" :).

Telerik team,
I have been looking around on your site and found an old post that specified "Object bound Hierarchy" has not yet been
implemented. I was wondering if it was added in a recent release, and/or if there was some kinda work around. I am trying to use the grid to create a FileExplorer that looks like the windows FileExplorer but works like the MACs Finder(you can drill down in the directories). Any help on this would be appreciated as I need to get this done and need to know if I should look somewhere else
for this behavior.
Thank you for your time.
