Hello,

I have a problem with exporting RadGridView using ToCsv() andToExcelML() methods.

While using AutoGenerateColumns property set to true everything works fine. 

However, when I'm trying to create columns in code in such a way:

with DataTemplate defined in XAML:

In this case everything looks fine and RadGridView displays columns properly, but ToCsv() methods creates a string consist only of white spaces.

Is there any solution to this problem?

Regards

Hi,
i'm  trying to bind a carousel with a CarouselDataRecordPresenter.

• When i'm binding with a datatable, it's OK ( detail code see 1))
• When i'm binding with an objet, the carousel have 2 elements but the property Lib of my object CarouselViewModel is not displayed ( detail code see 2).

     Remark:

     my visual Studio show me a error "Type or property expected " for the Data when i write the  Binding         Path=Data.CarouselViewModel.Lib

When i don't use the  CarouselDataRecordPresenter, the carousel displays 2 elements with the name of property (LIB) and its Value.
I tried other type of binding like Data[0] or Fields[Lib)..., but it doesn't work.  
What's wrong with my binding? 

Can you help me?

1) BINDING with DATATABLE
When i bind a carousel with a datatable , the carousel display the item of my row :
In my code behind :

DataTable

 

dt = new DataTable();

 

 

DataColumn dc = new DataColumn("Lib");

 

dt.Columns.Add(dc);

 

DataRow dr = dt.NewRow();

 

dr[

"Lib"] = "Item1";

 

dt.Rows.Add(dr);

dr = dt.NewRow();

dr[

"Lib"] = "Item2";

 

dt.Rows.Add(dr);

sampleRadCarousel.ItemsSource = dt;

In my Xaml :

 

 

<Style TargetType="{x:Type Controls:CarouselDataRecordPresenter}">

 

 

 

<Setter Property="Template">

 

 

 

<Setter.Value>

 

 

 

<ControlTemplate TargetType="{x:Type Controls:CarouselDataRecordPresenter}">

 

 

 

<StackPanel Margin="0,20,0,0" TextElement.FontWeight="Bold">

 

 

 

<Label Content="{Binding Path=Data[Lib]}"/>

 

 

 

<Label Content="test"/>

 

 

 

</StackPanel>

 

 

 

</ControlTemplate>

 

 

 

</Setter.Value>

 

 

 

</Setter>

 

 

 

</Style>

 

2) BINDING MODELVIEW
In code behind 

Collection

 

<CarouselViewModel> ListeCarousel = new Collection<CarouselViewModel>();

 

 

CarouselViewModel carouselview = new CarouselViewModel("item1");

 

ListeCarousel.Add(carouselview);

 

CarouselViewModel carouselview1 = new CarouselViewModel("item2");

 

ListeCarousel.Add(carouselview1);

sampleRadCarousel.ItemsSource = ListeCarousel;

In xaml :

 

 

<Style TargetType="{x:Type Controls:CarouselDataRecordPresenter}">

 

 

 

<Setter Property="Template">

 

 

 

<Setter.Value>

 

 

 

<ControlTemplate TargetType="{x:Type Controls:CarouselDataRecordPresenter}">

 

 

 

<StackPanel Margin="0,20,0,0" TextElement.FontWeight="Bold">

 

 

 

<Label Content="{Binding Path=Data.CarouselViewModel.Lib}"/>

 

 

 

<Label Content="2"/>

 

 

 

<Label Content="3"/>

 

 

 

</StackPanel>

 

 

 

</ControlTemplate>

 

 

 

</Setter.Value>

 

 

 

</Setter>

 

 

 

</Style>

 

 

Hi,
      I am using Telerik WPF control.I need to short multiple column in GridView through WPF.
      Can any one will help me for this.

I am using styles to override the control template of a GridViewCell.  In certain cases, I display a radcombobox.  In one case, I set the ItemSource of the combobox to a List<String>, but want to allow the user to type in values.  I set combobox IsEditable to True, which changes the display style of the combo.  It sort of works by binding to the combobox.Text property, but the behavior is a little off.  If I type a character in the editable combobox, I have to click several times to get the focus back into the combo so I can type another character.  Is there any way to keep the focus in the combobox or is there a better way?

Thanks in advance,
David Collins

Hi,

I was not able to Bind Checked Items in RadTreeView to a list of predefined entities.

What is the preferred approach bind the list of hierarchical data in two way mode to checked Items in tree. So that check/uncheck will  update the bound list.

I apologize if this is covered somewhere else but I have been unable to find it so far.  I'm trying to "sync" a detail screen with a Telerik gridview.  The user will edit the information on the detail screen and then save.  I want the save process to update the grid information but I want to be able to return to the record being edited.  This is a multi-user scenario so there is no guarantee that a record would return in the same position so I'm trying to come up with a way to "Find" the right record to fill the SelectedItem property.  I would like to be able to utilize the data's primary key to search the grid and selected that record, is this possible?  I've been looking at the FindRecord method but without success.

Thanks,
