We have upgraded to the new 2010.2.10.0914 version of the GridView (from version 2010.1.10.308).

In the prior version that we were using, when entering the filter row the grid still maintained the databound selected row. In the new version this does not seem to be the case. As soon as a cell in the filter row is clicked then the selected data row is no longer selected.

The behavior of maintaining the selected data, when entering into the filter row, is needed for our application. How can this be accomplished in the new version of the GridView?

Thank you for any help and information you can provide.

Dim element As RadElement = Me.gridViewHome.ElementTree.GetElementAtPoint(e.Location)

If TypeOf element Is RadCheckmark Then

If (IsNothing(gridViewHome.Rows(gridViewHome.CurrentRow.Index).Cells("User").Value)) Then

RadMessageBox.Show("Task Cannot Assign/UnAssign if the task", "Cannot Assign/UnAssign Task", MessageBoxButtons.OK, RadMessageIcon.Info)

GridViewSummaryRow

Hi,

I have created a grid that needs to show totals and highlight the totals if they exceed a certain amount. Like a time sheet going over 40 hours for a week or 8 hours in a single day.

I have not been able to find a way to capture the CellElement to modify the GridViewSummaryRow cells.

I have tried a few different ways such as the following.

   private void rg_CellFormatting(object sender, CellFormattingEventArgs e)
        {

            if (e.CellElement is Telerik.WinControls.UI.GridSummaryCellElement)
            {
                e.CellElement.DrawFill = true;
                e.CellElement.NumberOfColors = 1;
                e.CellElement.BackColor = Color.Crimson;
                e.CellElement.Font = new Font("Verdana", 10);
            }

}

I never see a GridSummaryCellElement come up during the formatting. I was wondering if I am just going about it wrong or maybe its the order in which I am constructing my grid?

Quick view of my load:
            BuildGrid();
            PinColumns();
            BindGrid();
            CreateSummaryRow();

I can provide more detail if needed.

Any thoughts?

Thanks,

Chris

Radspineditor inconsistencies? Validation and beep feedback

Hi-

I'm using the Radspineditor for numeric entry. It has a lot of conveniences that I'd like to keep, rather than switching to an entirely different control. One problem that we're running into though is an inconsistency in the way validation is getting handled:

When a character is appended to the text in the editor (let's say it already contains "0.00000"), most non-numeric characters will automatically be rejected- This sounds a windows "beep".

Some symbols, like an open-parenthesis or an underscore, don't cause the beep, but are still rejected. I've noticed that these symbols will also cause the "Validating" event for the RSE to fire off, while the non-numeric characters mentioned earlier will not. Even if I do nothing in my "Validating" event code, the offending character is rejected.

My task is to try to make the character-by-character validation behavior consistent, but I haven't found a way to do that with the events that are available. I need to always know during the validation event when a character will be rejected. Currently, I don't have any visibility of that: The beep-rejected characters don't fire the Validating event, and when Validating fires for the silently-rejected characters, I can't see the true text in the control.

Any suggestions? Is there something I'm missing?

thanks!

Appointment.Occurrences is read-only

I'm working with RadScheduler for Winforms, still working with the 2010_1_10_504 release, and I would like more control of the Occurrences collection of the Appointment object. With Exceptions, there is an Add method. But Occurrences seems to be read-only.

I want finer-grained control of the editing capabilities I have with Occurrences. I've got a custom appointment class, am using a custom appointment factory, custom dialogs for editing appointments and recurrence rules. I am writing Occurrences to their own table, and wish to maintain them myself.

Any tips on how to achieve this objective would be much appreciated. I'm aware that I can override CreateOccurrence, but have still not reached my objective.

Update: all the occurrences of my recurring appointment show up in the scheduler. However, I have apparently not succeeded in building the Occurrences collection for a recurring appointment. The recurrence icon does not show up on the various occurrences within the scheduler.

My main point is that there is an inconsistency in the way one can populate Exceptions and Occurrences. If I could handle both the same way, the coding I'm attempting to do would be easier.

Q2 2010 SP2 Theme

I'm just wondering why the theme color scheme is so much different after Q2 2010 SP2 then it was prior to the new service pack. The color scheme of the new theme doesn't seem to match other Telerik controls as well as the previous version and because of it the scheduler seems really out of place in my UI. It's unfortunate because SP2 patched a bug that I reported, but now I can't decide if the look of the UI or implementing this new feature is more important.

Is there anyway to go back to the SP1 office 2007 (lightblue) theme in SP2?

To clarify, I think the new theme looks more polished, with the new navigation buttons, appointments, etc. But I feel as if the move from a light blue to a darker blue on the theme makes the scheduler stick out among other Telerik controls with the same theme.

Drag and Drop using the RadTreeView

Hello

I have a simple question. I have trying to implement a simple drag and drop operation from a RadTreeView node to another .NET control (in my case it is a control that represents a model diagram). I have failed so far. Can I do that with the RadTreeView control? I certainly can do with the .NET treeview control.

Thanks for your help.

Regards

TabStrip captures arrow keys, ProcessCmdKey will not override that behavior

I'm working with 2010 Q1, and I cannot override ProcessCmdKey to trap the left and right arrow key events. It will work in a form without the tabstrip, but not in a form with a tabstrip. Is this a known issue?

My project is pretty far along using this version, and converting to the new version would basically require writing a new project and copying the code over. The automatic upgrade stuff in 2010 Q2 SP1 is not appearing, probably due to the fact that my project uses Q1 dlls. Replacing those dlls with Q2 versions causes a multitude of errors to appear.

Any ideas?

thanks,

David
