Multiline Textbox

[Forstmeier Peter]

Hi all togehter,

i have the following XAML in my Grid:

<Syncfusion:GridTemplateColumn HeaderText="Beschreibung" TextWrapping="Wrap"  MappingName="Description">
                    
                    <Syncfusion:GridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Description}"  TextWrapping="Wrap" />
                        </DataTemplate>
                    </Syncfusion:GridTemplateColumn.CellTemplate>
                    
                    <Syncfusion:GridTemplateColumn.EditTemplate>
                        <DataTemplate>
                            
                            <TextBox Text="{Binding Description, Mode=TwoWay}"
                                   ScrollViewer.VerticalScrollBarVisibility="Auto"
                                     Syncfusion:FocusManagerHelper.FocusedElement="True"
                                      AcceptsReturn="True"
                                     TextWrapping="Wrap"
                            />
                        
                        </DataTemplate>
                    </Syncfusion:GridTemplateColumn.EditTemplate>
                </Syncfusion:GridTemplateColumn>

I calculate the RowHight with:

QueryRowHeight="DataGrid_QueryRowHeight"
CurrentCellEndEdit="DataGrid_CurrentCellEndEdit"

Code is from google and the forum here..

Display the Multilie Text works as expected.

What i need to have is:

A editable textbox, with the possiblity to add new lines with the <CR> Key.

Thanks in advance

Peter

Hi Peter, 

 

Thank you for contacting Syncfusion support. 

 

We have analyzed your query. You can achieve your requirement by overriding the ProcessKeyDown event in GridCellSelectionController class. By default, in the SfDataGrid on pressing the Enter key, the currentcell is moved to the next row, you can overcome this problem by setting KeyEventArgs.Handled as false in ProcessKeyDown event. For your reference, we have added the code snippet and sample in below location. Could you please refer to it. 

 

Code Snippet: 

 

this.datagrid.SelectionController = new GridCellSelectionControllerExt(datagrid); 

 

public class GridCellSelectionControllerExt : GridCellSelectionController 

{ 

    public GridCellSelectionControllerExt(SfDataGrid dataGrid) 

    : base(dataGrid) 

    { 

 

    } 

    protected override void ProcessKeyDown(KeyEventArgs args) 

    { 

        if (args.Key == Key.Enter) 

        { 

            args.Handled = false; 

            return; 

        } 

        base.ProcessKeyDown(args); 

    } 

}
