How to populate and save to and from Datatable

Hi guys,
sorry if this has been asked before but so far i couldn't find such topic for C#. so again asking the experts to help me.
so i'm using VC# 2010 SP1, RAD Q2 2012.

so i have the following datatable and dataset. code below

DataSet SelPreDS = new DataSet();

DataTable SelPreDT;

SelPreDT = SelPreDS.Tables.Add();

SelPreDT.Columns.Add("ID", typeof(Int32));

SelPreDT.Columns.Add("Code", typeof(string));

DataColumn dc = new DataColumn("ParentCode", typeof(string));

dc.AllowDBNull = true;

SelPreDT.Columns.Add(dc);

SelPreDT.Columns.Add("Name", typeof(string));

SelPreDT.Columns.Add("Type", typeof(string

));

      SelPreDT.Columns.Add("isCheck", typeof(Boolean));

     SelPreDT.Columns.Add("Price", typeof(Int32));

and i add values to the datatable like this

DataRow dr = SelPreDT.NewRow();

dr[0] = id;

dr[1] = code;

dr[2] = ParentNoteID;

dr[3] = Name;

dr[4] = "Process";

dr[5] = true;
dr[6] = 6.66;

SelPreDT.Rows.Add(dr);

Exposing the event dispatchers

Hello,

Any chance y'all could expose the event dispatchers? By that I mean, specifically, ones like OnEditorRequired, OnEditorInitialized.

Reason being, we're extending from PropertyGrid in order to customize it into our application framework, and one of those customizable parts is having custom editors available. That'll give us flexibility what sort of hooks we want to incorporate.

The events themselves will work for now, but that starts to get somewhat decentralized from the control in an application workspace that is already dysfunctional as it is (ours not yours).

Thank you...

Best regards...

Recurrencerule format

Dear friend!
        I had created a common table in (SQL SERVER 2005) for storing input appointment from webform radscheduler.
        I want to retrieve the stored appointment and placed it into the winform radscheduler.

        But i can't able to place the appointment, because of the recurrence rule. The recurrence rule in radscheduler is differs in winform and webform. How can I set or convert the webform recurrence rule into winform recurrence rule.
    It is possible!
    Please help me. I hope that you will help...

add items and reorder problem

Hi

I have ListView in "detailsView" Mode with two columns.

Now I want to add Entries to this list.

Dim lvItem1 As New ListViewDataItem()

lvItem1.Item(0) = "CL1"

lvItem1.Item(1) = "1000"

lvItem1.Tag = New clsFoundationPlane("CL1", 1000)

Me.lvHorValues.Items.Add(lvItem1)

Dim lvItem2 As New ListViewDataItem()

lvItem2.Item(0) = "CL2"

lvItem2.Item(1) = "2000"

lvItem2.Tag = New clsFoundationPlane("CL2", 2000)

Me.lvHorValues.Items.Add(lvItem2)

Now I have two lines in my ListView but with no text in it. What have I done wrong?

Second question:
How can I reorder my entries. I have two buttons with "Up" and "Down". So that the selected item can be moved in the list upd and down.

Thanks Flo

Documentation of new Version

Hi,

I can understand if major changes have to be made to a module because of poor or faulty structural prior constructs.

All developers develop... (we all know of times where we didn't know... and made decisions...)

My frustration with the new version of the ChartView module is that I can't find the appropriate documentation - and I can't find examples. I have spend hours reviewing, checking, comparing and getting frustrated. For me, this has been a time consuming update. I believe the new charting module will have many possible advantages for the future but I have to get rolling in the here and now.

Could you give me links of examples. I might be missing some simple issues. But they are missing for me. I have a simple example:



BarSeries barSeries = new BarSeries("Anzahl", "mySelection");
barSeries.ValueMember = "Anzahl";
barSeries.CategoryMember = "mySelection";
radChartView1.Series.Add(barSeries);
radChartView1.DataSource = dt;

Why shouldn't that work? I get the grid, the values on the x and y axes but not the data (the bars) displayed in the area.

However, it works if I do a Lineseries. However, lines are not appropriate in this application.

Waiting for your feedback,

Karl

Theme issues on version 2012.2.608.20

Hi all,

I've just upgraded my telerik winform components libraries to version 2012.2.608.20 and encountered some issues related to telerik theme. There are 2 issues that emerged:

I have a project that uses splash screen (I use telerik form and other telerik controls inside the splash screen). I used to use ThemeResolutionService.ApplicationThemeName property on my Form.Load handler to set theme for entire application and it worked fine. But now it always throws InvalidOperationException that says "Cross-thread operation not valid: Control 'SplashScreen1' accessed from a thread other than the thread it was created on.". I also try not to use telerik controls on my splash screen but it works fine. It looks like the theme engine tries to change the theme of the telerik controls inside the splash screen.
In designer environment I used to be able to change the controls' ThemeName property to for instance "TelerikMetro" as long as I have "TelerikMetro" theme component placed inside my main form. But now the property doesn't show "TelerikMetro" option even if I have placed "TelerikMetro" theme component inside my main form.

Is there any solution to handle this issues?

Thanks

Office2007Black

Hi

Since updating to the latest build (2012.2.608.20) the TREEVIEW does not accept the theme for Office2007Black.

I found the problem because I use "ThemeResolutionService" to globally set the application theme and it causes problems on the TREEVIEW when I use Office2007Black.

Any work arounds ?

Paul.
