Hi, i m ashrul

i have problem here, so i have radgridview like this, i have to set selected item on child, in my case last data in is the last selected item automatically from code behind without click.

but i can't handle that.

 

my code like this :

 int a = radTreeListView.Items.TotalItemCount;

 var selectedItem = this.radTreeListView.Items[a-1] as Data;

 

and Data is my property class.

so what i want is, if user add a new data in radgridview so its automatically selected from code behind.

 

thanks in advanced.

 

I'm trying to use ItemsSourceBinding. The list is displayed but the selected item is not commited to binded property (see attached picture).
XAML:

ViewModel:

This sample is based on SL sample attached by Maya here: http://www.telerik.com/community/forums/silverlight/gridview/binding-from-radgridview-to-radcombobox.aspx 

Hi,

I was wondering if there was a way to provide the format to display a formatted DateTime like we do with the DateTimeFormatString in other grids. I am looking to have the datatype of the field as DateTime to preserve the filtering. Any advice in this regard would be greatly appreciated.

 

Thanks,

Sri

Hey!

So. I'm having a RadGridView which looks something like this (simplified)

<Grid DataContext="{Binding}" Margin="5,5,5,5" MaxHeight="300" MinHeight="100">                                
                                <telerik:RadGridView x:Name="DeliverableTypesGridView" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"                                                                         
                                    ShowGroupPanel="False"
                                    SelectionMode="Single"
                                    AutoGenerateColumns="False"                                    
                                    CanUserReorderColumns="False"
                                    CanUserDeleteRows="False"
                                    CanUserInsertRows="True"                                    
                                    ShowInsertRow="True"
                                    ItemsSource="{Binding DeliverableTypes}">                                    
                                    <telerik:RadGridView.Columns>
                                        <telerik:GridViewSelectColumn />
                                        <telerik:GridViewDataColumn Header="Code" DataMemberBinding="{Binding Code, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}"  />
                                        <telerik:GridViewDataColumn Header="DeliverableType" DataMemberBinding="{Binding Description}" IsReadOnly="True" />                                        
                                                                       
                                        <telerik:GridViewComboBoxColumn Header="Due Date Rule"
                                                                        DataMemberBinding="{Binding DueDateRule.Description, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                                                                        ItemsSource="{Binding ReferenceData.AllDueDateRules}"                                                                         
                                                                        DisplayMemberPath="Description"                                                                        
                                                                        />                                                                               
                                        <telerik:GridViewCheckBoxColumn Header="Active"  DataMemberBinding="{Binding Active}" />
                                        <telerik:GridViewDataColumn Header="Comments" DataMemberBinding="{Binding Comments}"/>
                                        <telerik:GridViewDataColumn Header="Created By" DataMemberBinding="{Binding CreatedBy}" IsReadOnly="True" />
                                        <telerik:GridViewDataColumn Header="Created On" DataFormatString="{}{0:M/d/yyyy}" IsVisible="True" DataMemberBinding="{Binding CreatedOn}" IsReadOnly="True"/>
                                        <telerik:GridViewDataColumn Header="Last Modified By" DataMemberBinding="{Binding LastModifiedBy}" IsReadOnly="True"/>
                                        <telerik:GridViewDataColumn Header="Last Modified On" DataFormatString="{}{0:M/d/yyyy}" IsVisible="True" DataMemberBinding="{Binding LastModifiedOn}" IsReadOnly="True"/>                                        
                                    </telerik:RadGridView.Columns>
                                </telerik:RadGridView>
                            </Grid>

Concentrate on the GridViewComboBoxColumn. I'm successfully binding my item source to the combo box on every row has.
But the thing is that when the Grid appears on the screen the GridViewComboBoxColumn  column shows no information.

As I'm using WPF MVVM pattern I'm having a public ObservableCollection<DeliverableTypeModel> DeliverableTypes property on a ManageDeliverableViewModel.cs whcih I use as DataConext. My DeliverableTypeModel.cs has a DeliverableDueDateRule Property as well.

My intention is to show the value that the DeliverableDueDateRule Property  has under this field in the grid ,
but I get a blank column instead.
The thing that is working is that when I click on a cell of the blank column I get a comboBox whith the items on the items source

Thanks!

Hi there,

is there no german localization for the spreadsheet ribbon?

Best regards

 

Is there a way to serialize/deserialize a RadCartesianChart instance? I saw methods to export to an image, but that is not what I want.

I have an application that creates/shows instances of RadCartesianChart. I want to render the same chart in a separate application and let users interact with it. Are there any other approaches that can be recommended to handle this problem?

 

Kind Regards,

Albert

Hi, I am creating a project using the valiadtion as IDataErrorInfo, but I need to create a simple edit form that the RadMaskedTextInput components have the Value option filled with a value.

 

This is my example TextInput:

                <telerik:RadMaskedTextInput Value="{Binding Interessado, Mode=TwoWay, ValidatesOnDataErrors=True, NotifyOnValidationError=True, ValidatesOnExceptions=True}"
                                            x:Name="Interessado" 
                                            EmptyContent="Nome ou razão social"
                                            Culture="pt-BR"
                                            Mask=""
                                            InputBehavior="Insert"
                                            UpdateValueEvent="PropertyChanged" 
                                            HorizontalAlignment="Stretch"/>

 

And this is my validation class:

    public class Validations : IDataErrorInfo
    {
        public string Interessado { get; set; }

        #region IDataErrorInfo

        public string this[string columnName]
        {
            get
            {
                if ("Interessado" == columnName)
                {
                    if (String.IsNullOrEmpty(Interessado))
                    {
                        return "Campo Nome do Interessado é obrigatório!";
                    }
                }
   
                return "";
            }
        }

        public string Error
        {
            get { throw new NotImplementedException(); }
        }
    }

 

So, how can I set the Value with a text (because I am using the Value option for Binding)?

Is it possible to change the order of the items used in the filter?

 

Now they are being set by the order of the columns of the gridviewcolumns

Hi. 

I had Page with RadRichTextBox like word format.

It almost same with default telerik word project.

I want RadRichTextBox filled in Grid's RowDefinition(1), could resize.

Please see attched files. How can I fill it to row ?

sorry for so basically.

thanks.

Nothing happens if you try to change order of items in grid grouping panel by drag and drop. However it worked in version 2015.

Any idea? Is that bug? I could not find any solution on forum too.

Thanks for any hints!
