RadGrid: Problem with AutoGenerate Columns=false

Hi!

I have encountered a problem with RadGrid when using AutoGenerateColumns=false. Having defined the required columns and setting the property to false (both in code and in the property designer) the resulting output when the grid is bound to a data reader is far from what is to be expected.

The columns I specify do not take on the values defined by the fields assigned to them, rather they display the contents of coumns in the order the query returns them, append the remaining columns (ignoring the autogenerate setting) to my defined set, ie

Query returns ID, strSurname, StrForename, strPhone, strLocation

I defined a simple grid (as a test) to display only the column strSurname with the heading "Surname"

What happened was I got a grid with columns "Surname", lngID, strSurname, strForename, strPhone

With 'Surname' displaying the values for lngID, 'lngID' displaying the values for strSurname etc.

DataEditFormatString in GridView

Hi,

I'm trying to list some information about tasks and when I'm trying to set a date/time entry, I'm only able to edit the date part, not the time part.

I've tried to change the DataEditFormatString to be able to change the time part but without success.

What am I doing wrong?

Here is a code of one of the GridViewDateTimeColumn.

    
                        gridViewDateTimeColumn1.DataEditFormatString = "{0:D}"; 
        
                        gridViewDateTimeColumn1.DataType = typeof(System.DateTime); 
        
                        gridViewDateTimeColumn1.FieldAlias = "DateBegin"; 
        
                        gridViewDateTimeColumn1.FieldName = "DateBegin"; 
        
                        gridViewDateTimeColumn1.HeaderText = "DateBegin"; 
        
                        gridViewDateTimeColumn1.IsAutoGenerated = true; 
        
                        gridViewDateTimeColumn1.UniqueName = "DateBegin"; 
        
                        gridViewDateTimeColumn1.Width = 140;

Thanks,

GroupSummaryEvaluate Event

1. Thanks for fixing the typo (shuld be documented in the Release Notes)
2. In my app The event does not get fired, I use it to add an indication about Item Counts per Group.

What's the strategy to update Group Summaries with custom data?
This is the code I currently use:

    
               void OctopusGridView_GroupSummaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e) 
        
                    { 
        
                        string suff = String.Concat(" (", e.Group.RowCount.ToString(), ")"); 
        
                        if(e.FormatString.EndsWith(";")) 
        
                        { 
        
                            e.FormatString = e.FormatString.Substring(0, e.FormatString.Length - 1); 
        
                        } 
        
                        if (!e.FormatString.EndsWith(suff)) 
        
                        { 
        
                            e.FormatString = String.Concat(e.FormatString, suff); 
        
                        } 
        
                    }

RadButton and Shortcuts

I have created a simple winform, added a RadButton, hooked up a click event handler, and then attempted to assign shortcut keys to it but cannot get it to work at all. I am using 2010 Q1 release.

Is there a bug? If you could post a working sample of accomplishing this, I would appreciate it.

GridViewMaskBoxColumn decimal problems sollutin

We had quite lot problems with the GridViewMaskBoxColumn in Numeric masktype. We use "," not "." for decimal point that coused lot of bugs in the GridViewMaskBoxColumn. And altought the grid was setted to our localization setting the GridViewMaskBoxColumn still used the point. So here is the sollution what we figured out with the help of the telerik team.

This will hold the new row after we begin the edit.

    
            Private newRow As Telerik.WinControls.UI.GridViewDataRowInfo 
        
Private Sub RadGridView1_RowsChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCollectionChangedEventArgs) Handles RadGridView1.RowsChanged
 
If e.Action = Telerik.WinControls.Data.NotifyCollectionChangedAction.Add Then
 
newRow = 
 
TryCast(e.NewItems(0), Telerik.WinControls.UI.GridViewDataRowInfo)
 
End If
 
End Sub

In CellEndEdit event we replace the point with the comma. If the row has an index of -1 then thats a newrow.

    
            Private Sub RadGridView1_CellEndEdit(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles RadGridView1.CellEndEdit  
        
                    If e.RowIndex >= 0 And e.RowIndex < RadGridView1.Rows.Count And e.ColumnIndex >= 0 And e.ColumnIndex < RadGridView1.Columns.Count Then  
        
                        If RadGridView1.Columns(e.ColumnIndex).GetType.Name = "GridViewMaskBoxColumn" Then  
        
                            Dim cell As Telerik.WinControls.UI.GridViewCellInfo = RadGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex)  
        
                            cell.Value = cell.Value.ToString().Replace("."c, ","c)  
        
                        End If  
        
                    Else  
        
                        If newRow IsNot Nothing Then  
        
                            For Each cella As Telerik.WinControls.UI.GridViewCellInfo In newRow.Cells  
        
                                If cella.Value IsNot Nothing And cella.ColumnInfo.GetType.Name = "GridViewMaskBoxColumn" Then  
        
                                    cella.Value = cella.Value.ToString().Replace("."c, ","c)  
        
                                End If  
        
                            Next  
        
                        End If  
        
                    End If  
        
                End Sub

In the CreateRow we can give starting values for the cells if they were left blank.

    
            Private Sub RadGridView1_CreateRow(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCreateRowEventArgs) Handles RadGridView1.CreateRow  
        
                    For i As Int32 = 0 To e.RowInfo.Cells.Count - 1  
        
                        If IsDBNull(e.RowInfo.Cells(i).Value) Then  
        
                            If RadGridView1.Columns(i).GetType.Name = "GridViewMaskBoxColumn" Then  
        
                                Dim oszlop As Telerik.WinControls.UI.GridViewMaskBoxColumn  
        
                                oszlop = TryCast(RadGridView1.Columns(i), Telerik.WinControls.UI.GridViewMaskBoxColumn)  
        
                                e.RowInfo.Cells(i).Value = "0,00" 
        
                            End If  
        
                        Else  
        
                            If e.RowInfo.Cells(i).Value = "" Then  
        
                                If RadGridView1.Columns(i).GetType.Name = "GridViewMaskBoxColumn" Then  
        
                                    Dim oszlop As Telerik.WinControls.UI.GridViewMaskBoxColumn  
        
                                    oszlop = TryCast(RadGridView1.Columns(i), Telerik.WinControls.UI.GridViewMaskBoxColumn)  
        
                                    e.RowInfo.Cells(i).Value = "0,00" 
        
                                End If  
        
                            End If  
        
                        End If  
        
                    Next  
        
                End Sub

Scheduler Edit Dialog Execution Flow

We are creating a custom appointment editor dashboard that implements the IEditAppointmentDialog interface. We are not interested in inheriting from the stock dialog form however; this application addresses a business need that requires a highly customized UI for our custom Appointment derived type, and the limitations of inheriting fromt the stock form are not acceptable for this situation.

That said, casual object browser inspection of the EditAppointmentDialog lets us see that the Appointment is passed to the editor dialog by value via the Edit Appointment function. We were actually expecting that to be a reference. What we need to know, then, is what mechanism is used to pass the edited IEvent back to the Scheduler control?

Even better would be a simple overview of the the edit dialog flow. I know we could go look at the source, but if its a fairly simple then I'd rather not have to dig.

change the color of gridrow on mouse hover

Hi telerik team,

I am trying to use the RAD grid view for winform. What i need is to change the color as the user moves the mouse over the rows.
I.e. A row should change its color when user hovers the mouse and as the user leaves the mouse from this row, it should again change color. This is very critical for me so any help will be appreciated.

Please reply ASAP

Thanks
Ravi
