Hi,
I'm developing with VS 2012 and Telerik control version 2013.2.724.40.
I tried to bind string values dynamically to the GridView in code.
The program first reads from a array, where it can decide the type of the column(e.g. string, double). If the data can be presented as a double value, then I create a customized GridView column with RadMaskedTextInput. I'd like to format the number by setting the Text property. The data binding works fine, however, it seems the numbers (e.g. 1000.1) are not shown as expected (e.g. 1,000.10). 

I could attach all source code if needed. Thanks in advance.

Hello everybody,

I have a dataform with some fields declared as nullable double (i.e. double?). When I start my application, it is OK I have empty fields for the nullable parameters. But if I start to fill one of these fields and then I delete what I have written, I cannot let the field empty again. The field is boxed with a red frame and a validation exception disables end edit button.

Do you have an explanation and a method to let my fields empty ? I tried to modify the validation exception but I cannot find where they are defined.

Thank you !

Is there a way to change simple elements that are nested inside the ScheduleView's ControlTemplate, like NavigationHeader -- for example the border's background colour--using Style Setters?

Example: I'd like to apply the Windows8 theme, and then specify a different colour for NavigationHeader.

It seems a shame to generate the ControlTemplate's 6100 some-odd lines of XAML to change some minor elements in the ScheduleView's ControlTemplate.

Hello everyone,

 I am facing an issue using DataForm. I have an  abstract class IBacktestOption and several inherited classes. Let's take only two of them : OptionCall and CallSpread. These classes share 4 arguments with IBacktestOption and have their own arguments.

Here is the IBacktestOption class :



This is OptionCall class :

This is CallSpread class :
In my view I have my DataForm declare like this :

And in my view model I initialize my Collection (I use a ViList, which is a structure almost equivalent to a simple List) with an element of OptionCall type :



When I start my application, everything is fine, I have what I want i.e. my DataForm with my 6 fields : "Strike", "ID", "Gearing", "GlobalCap", "GlobalFloor", "Nom".
In my page, I also have a RadComboBox which enables me to choose which formula I want to use. This combobox is binded to this field in my view model :

When I use the ComboBox to change the formula, a new element is added to the DataForm and here is my issue : this new element only have the fields of IBacktestOption class. And when I use Navigation buttons to go back on my first element (OptionCall), the number of fields of the element have been reduced to 4 ("Gearing", "GlobalCap", "GlobalFloor", "Nom").

I want to know if it is possible to have the fields of the inherited classes instead of the ones of IBacktestOption.


Moreover, in reality I don't need to have a list of IBacktestOption in my DataForm, I only need to have the current option (the one which is selected in the combobox). So, I have tried to empty my List when I change the option type in the combobox :

It works, I have the good number of fields for each option type. But, I need to click on the Next Item Navigation Button to reach my element. Indeed, the first one is empty. It is not really handy for a user. So, I also want to know if there is a way to click on this button automatically.

Finally, I have a last request. As, I don't really need a List for my elements, I tried to use a IBacktestOption instead of a ViList<IBacktestOption> in BactestOpt field. But I didn't manage to have fields printed in DataForm, the DataForm was empty...

Thank you very much for your help.

Hello,

Do you know any solution to make a good connection to Sybase IQ?

Thanking in advance,

I have a GridView where the GridViewColumns are created dynamically. We now have data in a column that can sometimes be null. I have kind of figured out how to use the Converter from the binding to change the value based on the value coming in - but this did not fix it. When I click on the filter It throws the error that must be of type Int64.

Here is the code that builds the column:
 Here is the converter: 
You can see I commented all most of the code out on the converter. I was just trying to get it to work. The value was coming back as the type - so I'm not sure whats going on there.

So I really have to issues here:
1) How to properly set the converter on the column datamember binding.
2) Why does the filter still recognize the null value even though I set the value to "N/A"

I have a grid that we need to bold the text when the value changes...the code Im using is in the CellEditEnded event handler:

void GridView_CellEditEnded(object sender, GridViewCellEditEndedEventArgs)
{
if(e.NewData != e.OldData)
{
e.Cell.FontWeight = FontWeights.Bold;
}

} 

This works fine...BUT when I switch rows the style goes back to its original style. My use case requires that ALL changed values remain bolded.

How can I achieve this?

Thanks,
Ron

Hey guys,

I have functionality to dynamically change themes via StyleManager.ApplicationTheme. Whenever the user changes themes, there is a roughly 20~30mb spike in memory usage that never seems to get garbage collected. Any idea on what would cause this?

The following code is used to dynamically change the theme:

Thanks.

And I create the series using SeriesMapping and ItemMapping. When I run the application I can see both scroll bars but it seems to be disable, I can't scroll nor zoom the chart.

Hi
Is there any way to assign tool-tip to text in RadRichTextBox.

I had tried by assigning Cross-reference bookmark by using editor.InsertBookmark(...) and editor.InsertCrossReferenceToBookmark(... , ... , ..) method. Bookmark is implemented but there is tool-tip is missing.

So how to enable tool-tip which normally shows in MS word.

Any alternate ways?
