Telerik,
I have a grid where the first column is a checkbox column. When a checkbox is checked in any row for the first time, that checkbox shifts to the right within the column by a pixel or two. Even if the checkbox itself isn't checked, but a mouseclick occurs within the cell, the same effect occurs. I've experimented with multiple columns widths, thinking maybe I wasn't allowing enough room for the entire control, but nothing has worked. Is this a known issue with a solution?

Thanks,
Jeremy

Show image based on value in a different column

What would be the appropriate approach for displaying an image in column 1 with the value of column 2.

For example, if column 2 is a status column and when the status is "GOOD" I want image1 to be displayed but when its "BAD" I want image2 to be displayed. How would I handle this? What approach would have the best performance when there are a large number of rows? We have one grid that contains over 100,000 rows of data.

Thanks for the help.

Format Header column if grouping allowed

How can I change the format of the header text, e.g. to italics, depending on whether grouping is allowed? Is the header row processed by the CellFormatting event? From the examples I've seen, since the type of row is not checked, I assume only data rows go there. I tried the code below in the form load event, but Italic is a read-only property, so I can't change it. I'm also counting on the fact there that the columns and cells are in exactly the same order, which may not be the case.

Dim i As Integer

For i = 0 To Me.TblUsersRadGridView.ColumnCount - 1

If Me.TblUsersRadGridView.Columns(i).AllowGroup Then

Me.TblUsersRadGridView.MasterGridViewInfo.TableHeaderRow.Cells(i).CellElement.Font.Italic = True

End If

Bind to Query?

I have a combo box of part numbers on a form and I want to pass the selected value of the item to a query to build a radgridview. In ASP.NET this was easy as you just passed in the paramaters. How would I go about this in WinForms?

Below is the Query that runs and I pass in Part Number and Facility and in ASP.NET it works wonderful. Would I need to setup an OleDbConnection connection? Like in http://www.telerik.com/help/winforms/grid_binding-to-datareader.html this example? How do I pass in the paramaters each time a new PN is selected from the ComboBox.

    
            WITH BOMCTE    
        
            AS   
        
            (    
        
              SELECT *    
        
              FROM MBM    
        
              WHERE BPROD = @PN  
        
              UNION ALL   
        
              SELECT MBM.*    
        
              FROM MBM    
        
                JOIN BOMCTE    
        
                  ON MBM.BPROD = BOMCTE.BCHLD and MBM.BMBOMM = BOMCTE.BMBOMM  
        
            )    
        
            SELECT DISTINCT cast(BCHLD as varchar(100))as ChildID, cast(BPROD as varchar(100))as ParentID, BSEQ as Sequence, IABC as 'ABC Code', ICOND as 'Condition Code', IDESC, IDSCE as '2nd Desc', ICITYP as Type, ICLAS as Team  FROM BOMCTE  
        
            INNER JOIN IIM on BCHLD = IPROD  
        
            INNER JOIN CIC on BCHLD = ICPROD  
        
            UNION ALL 
        
            SELECT DISTINCT cast(ICPROD as varchar(100))as ChildID, cast(NULL as varchar(100))as ParentID, 0 as Sequence, IABC as 'ABC Code', ICOND as 'Condition Code', IDESC, IDSCE as '2nd Desc', ICITYP as Type, ICLAS as Team   
        
            FROM CIC

            WHERE ICFAC = @FAC and ICPROD = @PN Order by Sequence

ConditionalFormattingObject is not working on Null Cells

I want to be able to highlight all rows that have a null value in a certain column. However when i try to use the following object its not working on null values.

Im calling this on the load of my form, or should i be calling this on the rowformatting event?

Private

Sub SetConditions()

Dim obj As New ConditionalFormattingObject("MyCondition", ConditionTypes.Equal, System.DBNull.Value.ToString, "", True)

obj.CellForeColor = Color.Red

obj.RowBackColor = Color.Yellow

Me.RadGridView_SessionData.Columns("Assignment").ConditionalFormattingObjectList.Add(obj)

End Sub

Any ideas!

ShowAllDayArea not working

Hi,

I'm using Q3 of 2009 libraries and I'm trying to hide the AllDay area to force all appointments to show up on the hour rows. I'm doing the following in the form constructor:

                    SchedulerDayView dayView = radScheduler1.GetDayView();         
            dayView.ShowRuler = false;         
            dayView.ShowAllDayArea = false;         
            dayView.DayCount = 1;         
            dayView.AppointmentTitleFormat = "{2}";         
            dayView.WorkTime = new TimeInterval(TimeSpan.Zero, TimeSpan.Zero);         

All properties work fine, except for the ShowAllDayArea. The area still shows up in the dayview. Is there another property I'm missing? Thanks.

P.S. Also, is it normal for the style settings on views to reset every time the view is changed? Say I set up my day view as above and then switch to Week View. When I come back to DayView, all my settings have to be done again.

highlight button

Buttons added to the Ribbon bar in design time and dynamically seems to have the different behavior on mouse hoover. Meanwhile when I move mouse over buttons added in design time they are highlighted, dynamically added button are not highlighted. How can I set up this behavior thru program code?

Here is my method for adding buttons to the button group:

private void AddItemToButtonGroup(RadRibbonBarGroup group, String ItemName, String ItemText, String ItemDescription)

{

RadButtonElement item = new RadButtonElement();

item.DisplayStyle = DisplayStyle.ImageAndText;

item.TextImageRelation = TextImageRelation.ImageBeforeText;

item.ImageAlignment = ContentAlignment.MiddleCenter;

item.Name = ItemName;

item.Text = ItemText;

item.ShowBorder = true;

item.TextWrap = true;

item.Margin = new Padding(1);

item.TextAlignment = ContentAlignment.MiddleCenter;

item.ToolTipText = ItemDescription;

item.MaxSize = new Size(80, 80);

item.Click += new EventHandler(Item_Click);

group.Items.Add(item);

}

Creating Charts in the Background

Hello,

I am working on a windows service that can generate Charts as png files and then email them to recipients. I would like to leverage RadChart for this. I've already gotten my charts nice and pretty in my fat client, but now I want to do the same thing in the windows service. Is this possible? The data is available to the windows service, so hopefully it's just a matter of instantiating the radChart object, setting the parameters, binding to the dataset, and then calling the export function.

Thanks!

Jeremy
