[Solved] RadGridView ItemsSource ?

[Marjeta Segrec]

Hello.

In my Silverlight project I'm using for Data manipulation C1.Silverlight.Data.DataView (ComponentOne). When I set RadGrid ItemsSource is RadGrid empty (not populated with data). What is the problem ?

Private Sub PopulateData()

        Me.RadGrid.AutoGenerateColumns = True
        '
        Dim dt As New C1.Silverlight.Data.DataTable("Customers")
        '
        dt.Columns.Add("FirstName", Type.GetType("System.String"))
        dt.Columns.Add("LastName", Type.GetType("System.String"))
        '
        For a As Integer = 0 To 10
            Dim newRow As C1.Silverlight.Data.DataRow = dt.NewRow
            '
            newRow("FirstName") = String.Concat("FirstName_", a)
            newRow("LastName") = String.Concat("LastName_", a)
            '
            dt.Rows.Add(newRow)

        Next ' a As Integer = 0 To 10
        '
        Me.RadGrid.ItemsSource = dt.DefaultView
End Sub ' PopulateData()

 

Thanks for your answer.

Hello Marjeta,

Unfortunately you cannot achieve this using auto-generated columns. I've made for you small demo to illustrate you how this can be done (attached).

Hi Vlad,

I had a look of your demo, but it doesn't show how to archive auto-generated columns.. you used fixed columns: ID and Name.

I want to archive auto-generated columns in RadGridView with this http://silverlightdataset.codeplex.com/. Do you have a demo?

 <telerik:RadGridView Name="RadGridView1" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerikGridView:GridViewDataColumn HeaderText="ID" DataMemberPath="ID">
                    <telerikGridView:GridViewDataColumn.CellStyle>
                        <Style TargetType="telerikGridView:GridViewCell">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate TargetType="telerikGridView:GridViewCell">
                                        <TextBlock Text="{Binding ID}" />
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </telerikGridView:GridViewDataColumn.CellStyle>
                </telerikGridView:GridViewDataColumn>
                <telerikGridView:GridViewDataColumn HeaderText="Name" DataMemberPath="Name">
                    <telerikGridView:GridViewDataColumn.CellStyle>
                        <Style TargetType="telerikGridView:GridViewCell">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate TargetType="telerikGridView:GridViewCell">
                                        <TextBlock Text="{Binding Name}" />
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </telerikGridView:GridViewDataColumn.CellStyle>
                </telerikGridView:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

it works (I found it needs to remove the AutoGeneratedColumn="True")
Thanks very much!

Vlad,

ColumnsWidthMode="Fill" seems not working either in xmal or in code.
