Reference Errors

Hello,

I am in the process of evaluating the WinForms Controls. Actually, when I saw the Bubble Bar in the Demos, I was convinced I need Telerik to go on with my project. However, I am trying to even start a project for the last two days and nothing seems to be going right, let alone set up a BubbleBar, which now, I have come to understand that it is not a native (Rad) control, but a derrivative.

Anyway, here's the problem. I tried to isolate the BubbleBar to another project (drawing from your demo source code). It seemed impossible to get the references right. So, I open a form and drag a label in it. I am thinking: "all relevant references must be inserted automatically now". And indeed they are (image1.png). You can see all controls in design time (image2.png). But, as soon as i try to compile, I get an error for each control as if I had never inserted a reference (image3.png). If it helps, in image4.png you can see my intellisense showing no namespaces other than "Examples", for Telerik.

What am I doing wrong?

Thank you in advance,
N.

PS:
I am working on VS2010, but later may be working on VS2008 as well.

[Solved] Esc in GridViewDateTimeColumn inside radDataGridView after I did an e.Cancel = true in Row Validation

I am having a problem and had been searching the web and couldn't find anything that will help me.

this is my problem.
Im working in WinForm , c#

I have a grid where is a Column of type **GridViewDateTimeColumn**.
When the user update a row I check it in the event **RowValidating** and if I get a repeated date or other error I show the user a message and I do **e.cancel = true** to not validate the row.
But then If I press ESC. I cannot cancel all the changes like it usually does before
Any idea how to do it?

Here is my code:

private void grdPirteyMenahel_RowValidating(object sender, RowValidatingEventArgs e)

{

try

{

Cursor.Current = Cursors.WaitCursor;

if (e.Row != null)

{

//Generate a service to connect to DB

var factory = new MezumanimChannelFactory<IKerenService>(ServiceConsts.SERVICE_KEREN);

var service = factory.CreateChannel();

string sError = string.Empty;

//here I call a SP in the database that check if the dates are correct (column of dates are call it "MiTaarich" and "AdTaarich".

//The SP return a String with the error, if there is no error it will return and empty string

sError = GetErrorPirteySacharMenahel(Convert.ToDateTime(e.Row.Cells["MiTaarich"].Value), Convert.ToDateTime(e.Row.Cells["AdTaarich"].Value), Convert.ToInt32(e.Row.Cells["Kod"].Value));

if (sError != string.Empty)

{

e.Cancel = true;

RadMessageBoxHelper.Alert(sError);

}

catch (Exception ex)

{

Elad.Mezumanim.Client.Utils.Log.LogUtil.write(ex);

e.Cancel = true;

RadMessageBoxHelper.Alert(Messages.DataDisplayError, this);

}

finally

{

Cursor.Current = Cursors.Default;

}

I also tried adding this code when i get the error:

DataTable dt = (grdPirteyMenahel.DataSource as DataTable);

dt.RejectChanges();

But this recover the value of date as it was before (what is good) but doesn't let me get out of the row when I press ESC

Any idea how to solve it?

thank you very much
best regards
Iair

Chartview Trackball text format

Hi,

I'm currently working with implementing new chartview in winform application.
I activate the trackball to show informations like in this sample
http://www.telerik.com/help/winforms/chartview-features-trackball.html

In this sample, informations are displayed in color, each on a new line and with the LineSeries name.

X - 3: 23
Y - 3: 7

But when I copy the same code in my solution, I view
"X 23 Y 7"

Is there an option to set the default text format ?
If not, do you have sample for using TextNeeded event to build this text formated with axes information ?

Thanks

[Solved] Underline issue with Tables and PDF Export

Hi,

I've run into an issue with underlining a text span that is in a table cell. When I create the content of the cell by doing the following:

row = New TableRow

cell = New TableCell()

p = New Paragraph()

sp = New Span()

sp.Text = "Benefit Start"

sp.UnderlineType = UI.UnderlineType.Line

p.Inlines.Add(sp)

row.Cells.Add(cell)

table.Rows.Add(row)

The underline extends past the final character. See the attached 'underlineissue_richtextbox.jpg' for an example, this jpg also shows the same text/paragraph added to the section outside of a table and it works fine.

The problem is even worse when I export the document to a PDF as all the underlines are too wide. See the second attachment for an example.

Is there a work around for this issue or am I doing something wrong?

Optimizing GridViewComboBoxColumn

Hi,

I have a RadGridView that has a GridViewComboBoxColumn containing 40,000+ values through data binding. Viewing the combobox values in every cell under that column is taking a few seconds. I think the reason for this sluggishness is because it loads up the values only when a cell is clicked. So I'm wondering if there's any way to optimize this behavior.

Thanks!

DateTimePicker Canceling the ValueChanging Event

Hi,

I have a form that allows the user to change from and to date.
But if the user changes the "to date" to an illegal date (defined by the database) the user will get an message where he can override this error or not. If hi does not override it, i want the date to be reset (cancel the valuechanging) event.
But the value in the datetimepicker stays at the date selected by the user regardless of me doing cancel = true or not.

How can i achieve this functionality without triggering the change event once again?

Regards
