[Solved] Bind HyperlinkButton in GridViewDynamicHyperlink and open child window

[Gaurang]

Hi Everybody,

I am developing silverlight Application. In that I use Telerik Silverlight RadGrid contorls. I develope a cutome gridview in that now I want to bind 

GridViewDynamicHyperlinkColumn

or

GridViewHyperlinkColumn

runtime for that I create one DataTamplate with HyperlinkButton/Hyperlink and bind it into GridView at runtime in Autogenerate event. But my problem is that child window is not open and if try to change somethink it give me catastrophy error.

<Grid.Resources>
                            <telerikcontrols:GridViewHyperlinkColumn x:Name="GridViewHyperLinkColumnTemplet">
                                    <telerikcontrols:GridViewColumn.CellTemplate>
                                        <DataTemplate>
                                            <HyperlinkButton x:Name="HyperLink" Click="HyperLink_Click" HorizontalContentAlignment="Center" VerticalContentAlignment="Center"/>
                                        </DataTemplate>
                                    </telerikcontrols:GridViewColumn.CellTemplate>
                            </telerikcontrols:GridViewHyperlinkColumn>
                            <telerikcontrols:GridViewDynamicHyperlinkColumn x:Name="GridViewDynamicHyperlinkColumnTemplet">
                                <telerikcontrols:GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <HyperlinkButton x:Name="HyperLinkButton" Click="HyperLinkButton_Click"  HorizontalContentAlignment="Center" VerticalContentAlignment="Center"/>
                                    </DataTemplate>
                                </telerikcontrols:GridViewColumn.CellTemplate>

GridViewDynamicHyperlinkColumnTemplet = new GridViewDynamicHyperlinkColumn();
                GridViewDynamicHyperlinkColumnTemplet.Header = e.Column.Header;
                //GridViewDynamicHyperlinkColumnTemplet.DataMemberBinding = new System.Windows.Data.Binding() { Path = new PropertyPath(hrplbtn) };

                GridViewDynamicHyperlinkColumnTemplet.DisplayIndex = grid.Columns.Count;
                e.Column = GridViewDynamicHyperlinkColumnTemplet;
            }
            else
            {
                e.Cancel = true;

Hello Ross,

Thanks for your reply.
I have already seen this link but it is not that much helpfull. Because I want to add a GridViewDynamicHyperlinkColumn run time which content a HyperlinkButton.

For that I have create one GridViewDynamicHyperlinkColumn with datatemplate in grid resources. Then replace (bind) it to my current custome grid in AutoGeneratingColumn event.

private void grid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
        {
            if (e.Column.UniqueName == "abc" || e.Column.UniqueName == "xyz")
            {
                GridViewDynamicHyperlinkColumn linkColumn = new GridViewDynamicHyperlinkColumn();
                linkColumn.CellStyle = GridViewDataColumnHyperLinkButton.CellStyle; // this is ok now working
                linkColumn.DataMemberBinding = (e.Column as Telerik.Windows.Controls.GridViewBoundColumnBase).DataMemberBinding;
                linkColumn.Header = e.Column.Header;
                if (e.Column.UniqueName == "abc")
                {
                    linkColumn.UniqueName = "Account";
                }
                if (e.Column.UniqueName == "xyz")
                {
                    linkColumn.UniqueName = "FullName";
                }
                linkColumn.DisplayIndex = grid.Columns.Count;

                e.Column = linkColumn;
            }
            else
            {
                e.Cancel = true;
            }
        }

Now my
HyperLinkButton_Click function is call but I want to bind Hyperlink Content run time how to do this and apply current cellsyle because now my cell style is changed which I do not want.

Thanks,

Hi All,

I have solve my problem this way.

private void AutoGeneratingColumnFunction(object sender, GridViewAutoGeneratingColumnEventArgs e, int count) // here count is total number of columns of the gridview
        {
            if (e.Column.UniqueName == "abc" || e.Column.UniqueName == "xyz")
            {
                GridViewDynamicHyperlinkColumn linkColumn = new GridViewDynamicHyperlinkColumn();

                if (e.Column.UniqueName == "abc")
                {
                    linkColumn.CellStyle = GridViewDataColumnHyperLinkButtonAccount.CellStyle; // this is data template
                    linkColumn.UniqueName = "Account";
                }
                else if (e.Column.UniqueName == "xyz")
                {
                    linkColumn.CellStyle = GridViewDataColumnHyperLinkButtonContact.CellStyle; // this is data template
                    linkColumn.UniqueName = "FullName";
                }

                linkColumn.DataMemberBinding = (e.Column as Telerik.Windows.Controls.GridViewBoundColumnBase).DataMemberBinding;
                linkColumn.Header = e.Column.Header;
                linkColumn.IsResizable = true;
                linkColumn.DisplayIndex = count;

                e.Column = linkColumn;
            }
            else
            {
                e.Cancel = true;
            }
        }

Below is my Data Template

<telerikcontrols:GridViewDynamicHyperlinkColumn x:Name="GridViewDataColumnHyperLinkButtonAccount" IsReadOnly="True">
<telerikcontrols:GridViewDynamicHyperlinkColumn.CellStyle>
<Style TargetType="telerikcontrols:GridViewCell">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerikcontrols:GridViewCell">
<Border Width="Auto" BorderThickness="1,1,1,1" CornerRadius="3,3,3,3">
<HyperlinkButton x:Name="hlbAccount" HorizontalContentAlignment="Left" Content="{Binding Account}"
VerticalContentAlignment="Center" Foreground="Blue" NavigateUri="{Binding AccountID}"
TargetName="_blank" Click="hlbAccount_Click" Width="Auto" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</telerikcontrols:GridViewDynamicHyperlinkColumn.CellStyle>
</telerikcontrols:GridViewDynamicHyperlinkColumn>
<telerikcontrols:GridViewDynamicHyperlinkColumn x:Name="GridViewDataColumnHyperLinkButtonContact" IsReadOnly="True">
<telerikcontrols:GridViewDynamicHyperlinkColumn.CellStyle>
<Style TargetType="telerikcontrols:GridViewCell">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerikcontrols:GridViewCell">
<Border Width="Auto" BorderThickness="1,1,1,1" CornerRadius="3,3,3,3">
<HyperlinkButton x:Name="hlbContact" HorizontalContentAlignment="Left" Content="{Binding Contact}"
VerticalContentAlignment="Stretch" Foreground="Blue" NavigateUri="{Binding ContactID}"
TargetName="_blank" Click="hlbContact_Click" Width="Auto"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</telerikcontrols:GridViewDynamicHyperlinkColumn.CellStyle>
</telerikcontrols:GridViewDynamicHyperlinkColumn>

Hyperlink click event

private void hlbAccount_Click(object sender, RoutedEventArgs e)
{
    GridViewRow parentRow = ((HyperlinkButton)sender).ParentOfType<GridViewRow>();
    if (((HyperlinkButton)sender).Content != null)
    {
        if (string.IsNullOrEmpty(((HyperlinkButton)sender).NavigateUri.ToString()) == false)
        {
            string AccountID = ((HyperlinkButton)sender).NavigateUri.ToString();
            ((HyperlinkButton)sender).NavigateUri = null; // here some ID not a link so it gives me Catastrphy error if I do not make it null
            var pageAccount = new PageAccount();
            pageAccount.Load(AccountID);
            Dispatcher.BeginInvoke(pageAccount.Show);
        }
    }
    else
    {
        ((HyperlinkButton)sender).NavigateUri = null;
    }
}
