Scheduler Timeline View

Is there a way I can set the start time and end time (working hours) of a day in timeline view?
Assuming the timescale is Days?

SchedulerTimelineView v = productionScheduler.GetTimelineView();

v.StartDate = DateTime.Today.AddDays(-6)

v.ShowTimescale(Timescales.Days);

??v.DayStartTime??

??v.DayEndTime??

Thanks in advance,

Expand / Collapse issue after adding rows

Dear Tekerik Team,

I'm using the following code (found on this forum) to expand / collapse a self referencing hierarchy grid:

RadGridView1.TableElement.BeginUpdate()

For Each row1 As GridViewDataRowInfo In RadGridView1.Rows

row1.IsExpanded = True

While the code works after the data are first loaded, it only collapses child rows when I add a new row to the dataset. I wonder if there is another method to collapse / expand all rows.

In the same vein and if I add a parent row to the self referencing hierarchy grid, the following code does not start the edit:

Dim

lastRow As GridViewRowInfo = RadGridView1.Rows(RadGridView1.Rows.Count - 1)

lastRow.EnsureVisible()

lastRow.IsSelected =

True

lastRow.Cells(

"Items").BeginEdit()

The above code would however start the edit on a child row. Is there any other method for a parent row?

Best regards,
Alain

Does Winform Chart control have 3D graph rendering support?

Hi Telrik,

I'm in process of evaluating the suitability of the telerik UI component particularly the Chart control. As per our requirement, we need to render different types of 2D and 3D charts. I know the WPF chart control best suits this requirement, but WinForm chart control is of more interest to me because of its inticipated ease of integration with my application. The problem is - I can't find a way to render 3D
charts with Winform chart control. Some links in this forum also suggests that Winform chart control
does not support 3D chart rendering.
http://www.telerik.com/community/forums/winforms/chart/suggestion-3d-chart.aspx
http://www.telerik.com/community/forums/winforms/chart/3d-graph.aspx

Does this(WinForm chart control not supporting 3D graphs) holds true even now? If yes, would it be possible to fix this in near future? If this is already fix, could you please provide a sample test application that demonstrate 3D chart rendering using WinForm Chart?

kind regards
Santosh

10, System.Drawing.FontStyle.Bold);

DataRowView row = e.DataItem as DataRowView;

e.SeriesItem.ActiveRegion.Tooltip = string.Format("{0} - #%", row["DS_PRODUTO"]);

e.SeriesItem.Name = string.Format("{0} - #%", row["DS_PRODUTO"]);

Can We User LINQ work on GridView's GridViewRowCollection?

I wanted to see if I can use LINQ on RADGridView's GridViewRowCollection (Telerik.Wincontrols.UI.GridViewRowCollection).

So I tried the following VB.NET code and got an error:

Dim lockedRows = _

From row In Me.dgTotalCosts.Rows _

Where row.Cells("colLocked").Value = True

Select New With {.Code = row.Cells("colCode").Value, _

.Description = row.Cells("colDesc").Value}

... when I then tried to check the value of lockedRows.Count. So i tried changing it around a little bit to:

Dim lockedRows As IEnumerable(Of Telerik.WinControls.UI.GridViewRowInfo) = _

From row As Telerik.WinControls.UI.GridViewRowInfo In Me.dgTotalCosts.Rows _

Where row.Cells("colLocked").Value = True

Select New With {.Code = row.Cells("colCode").Value, _

.Description = row.Cells("colDesc").Value}

But then got the following error (which I've somewhat abbreviated for briefness):

Unable to cast object of type 'WhereSelectEnumerableIterator'2[Telerik.WinControls.UI.GridViewRowInfo, VB$AnonymousType_0'6
[System.Object, ...]]' to type 'System.Collections.Generic.IEnumerable'1[Telerik.WinControls.UI.GridViewRowInfo]'.

So, the first question is, can I use LINQ on GridView's GridViewRowCollection. Secondly, if so, how (can you show me using my example code, above, where I'm trying to pull out the locked rows from a GridView (

Telerik.WinControls.UI.

RadGridView

)?

Thanks in advance for your help from a LINQ and RADGridView Newbie.

formatting row in hierarchical RadGridView

Hello all,
I am using a hierarchical RadGridView with 3-level and I would like that the rows of 2nd level and the rows of 3rd level that meet a search criteria (such as the Notes column contains the value "perizia") appear with a different backcolor.
I have used, as described in the manual online, the event radGridView_RowFormatting (object sender, RowFormattingEventArgs e) but while I scroll the ChildRows collection I lose the information about the class Telerik.WinControls.UI.GridDataRowElement essential to allow formatting the row read.
How can I do to get this highlighting ?

Best regards,
Mauro Fiore
