[Solved] GridViewCheckBoxColumn - Need Check Changed Event

Hi. I'm using a GridViewCheckBoxColumn, and I would like to have an event fire when the user changes the state of the checkbox by checking it, either by mouse or keyboard. Right now I've found that I can hook a variety of events that only fire after the cell's value is changed and the cell loses focus. But I need an event that actually happens as soon as the checkbox is changed. I'm running version 2012.1.321.20.

The only thing I've found that works is reaching into the virtualized cell, getting the RadCheckBoxEditorElement, and then hooking the PropertyChanged event on it. This is pretty ugly and cumbersome. It also presents a serious issue in that I don't know how to hook this event just once, since if I hook this event in the CellFormatting handler, I will end up hooking the event many, many times.

Is there a straightforward way to accomplish what I want?

Thanks.

Show image in cell using Bound Data

Hi there-

I hope this is an easy one...

I have a gridView that is bound to a stored procedure. One of the columns is of type GridViewImageColumn. The data returned from the proc is of Integer type. What I'm looking for is comparing the value (0 or greater than 0), whereas if 0, hide the image, if greater than 0, show the image.

So, given that, my first question is, how do I associate or add the image/png for the column/cell and how and when do I interrogate the bound data to show the image if greater than 0.

Hope this makes sense.

Thanks
Bob

GridViewComboBoxColumn (RadGridview for Winforms)

Hi,

I am using the "GridViewComboBoxColumn" in the radgrid win forms. I have created a type of GridViewComboBoxColumn and added it to radgridview.

            gridViewDDLCombbxColumn2.FieldName = "Data Base No";
            gridViewDDLCombbxColumn2.Name = "DataBaseNoCombo";
            gridViewDDLCombbxColumn2.HeaderText = "Data Base Num";
            gridViewDDLCombbxColumn2.DataSource = GetUserGrpData;
            gridViewDDLCombbxColumn2.DisplayMember = "DBNumber";
            gridViewDDLCombbxColumn2.ValueMember = "UserGroupID";
            this.radGridViewUserGroup.MasterTemplate.Columns.Add(gridViewDDLCombbxColumn2);

I am facing an issue when setting a default value or value from database to GridViewComboBoxColumn and while updating also I am not able to read the selected value from the GridViewComboBoxColumn.

For E.G:
this.radDdlDn.SelectedValue = currentRow.Cells["UserID"].Value;
The above statement can be used to assign the value to radDropdownlist.

String strddlValue=this.radDdlDn.selectedItem.Text
The above statement can be used to read the selected value from radDropdownlist.

Similarly how can we  perform the same operation with GridViewComboBoxColumn in radGridview

Thanks in advance
Shiva

Selecting a theme in VS 2012 RC

Hey,
I've added the "TelerikMetroBlue" theme to a control, but in the popup list it doesn't show it.
I've typed "TelerikMetroBlue" and run the app, the form uses the theme, except the form bar (the one with the form name, close button etc) is still in the default theme.

when i use:
ThemeResolutionService.ApplicationThemeName = "TelerikMetroBlue";
everything apper correctly.

so, the question is why doesn't it apper in the popup list, and why when inserted manually to a form it doesn't effect it's bar

Thanks,
Nadav

[Solved] Possible AllowDelete Bug

Hello,

I have a custom appointment class where I am setting the AllowDelete property to false.
I have set up the mapping like so:

appointmentMappingInfo.AllowDelete = "AllowDelete"

When I only this appointment in the edit dialog, the "Delete" button is disabled as expected.

But, when I press the "Del" key on the RadScheduler itself, the AllowDelete is ignored and the appointment is deleted.

I have worked around it by checking for the AllowDelete state myself in the AppointmentDeleting event:

Private Sub ArcoriScheduler_AppointmentDeleting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.SchedulerAppointmentCancelEventArgs) Handles Me.AppointmentDeleting

If e.Appointment.AllowDelete Then

' The RadScheduler does not prompt for series or instance when deleting an appointment with recurrence,

' which is how Outlook behaves: http://www.telerik.com/support/pits.aspx#/public/winforms/11810

If e.Appointment.MasterEvent IsNot Nothing Then

Dim confirmDlg As New RecurringAppointmentDeleteDialog

confirmDlg.AppointmentName = e.Appointment.Summary

Dim result As DialogResult = confirmDlg.ShowDialog()

If result = DialogResult.OK Then

If confirmDlg.DeleteType = RecurringAppointmentDeleteDialog.eDeleteType.Series Then

Me.Appointments.Remove(e.Appointment.MasterEvent)

e.Cancel = True

End If

Else

e.Cancel = True

End If

Else

e.Cancel = True

End If

But this seems like a bug.

I have looked at the RadScheduler source code and can see no reference to AllowDelete in RadScheduler.cs.
I do see the AllowDelete handling in EditRecurrenceDialog.cs to disable the Delete button.

Thanks.
