GridHyperlinkColumn to display non Uri text (like a double or string).

[David García]

Hello,

Is it possible in a GridHyperlinkColumn to display text that doesn't form an Uri?

I want to use the column type to display the value of a double or text property but, even it is shown, I keep getting an error message in the debug window that the type is not appropiate and can't be converted into an Uri.

With a converter can't be solved because an Uri constructor only admits a well formed url.

Also when the value is null or is an empty string another error is showin the debug window about can't create an Uri with a null.

I use the GridHyperlinkColumn to create a link so the user can click on it and open a window with other details relative to that particular row in the DataGrid.

Is there a way to achieve that? Either with the GridHyperlinkColumn or with anothert type of column.

Thanks in advance.

Hi David, 

Thanks for contacting Syncfusion support.  

You can achieve this requirement by using GridHyperlinkColumn and CurrentCellRequestNavigate event. We have prepared a simple sample to display non URI values as a hyperlink in column and open a new window when clicking on it. The sample is available in the following link for your reference.

Thank you so much for the reply back.

I was already aware of how to achive that exact functionality. What I meant is that in the debug window the following errors are shown:

Those errors are produced by the non Uri properties on the DataGrid. My question was if there was any way to avoid those errors.

Also if one of the vaules is null (instead of string.Empty) an exception is produced, is there a way to avoid that? (no always the value that has to be shown for strings is string.Empty, sometimes the value is null).

Thanks in advance.

Hi David, 

Thanks for the update.  

You can achieve the same by using GridTemplateColumn and SfDataGrid.CellTapped event without any binding error as shown in the following code example.  

Code example :  

<syncfusion:SfDataGrid Name="dataGrid" 

                       AutoGenerateColumns="False" 

                       CellTapped="DataGrid_CellTapped" 

                       ItemsSource="{Binding Employees}"> 

    <syncfusion:SfDataGrid.Columns> 

 

        <syncfusion:GridTemplateColumn MappingName="ID" AllowEditing="False"> 

            <syncfusion:GridTemplateColumn.CellTemplate> 

                <DataTemplate> 

                    <TextBlock Text="{Binding ID}" TextDecorations="Underline" Cursor="Hand" > 

                        <TextBlock.Style> 

                            <Style TargetType="TextBlock"> 

                                <Setter Property= "Foreground" Value="Blue"/> 

                                <Style.Triggers> 

                                    <Trigger Property ="IsMouseOver" Value="True"> 

                                        <Setter Property= "Foreground" Value="Red"/> 

                                    </Trigger> 

                                </Style.Triggers> 

                            </Style> 

                        </TextBlock.Style> 

                    </TextBlock> 

                </DataTemplate> 

            </syncfusion:GridTemplateColumn.CellTemplate> 

        </syncfusion:GridTemplateColumn> 

   </syncfusion:SfDataGrid.Columns> 

</syncfusion:SfDataGrid>
