StDataGrid GridColumnSizer.Refresh

[Bobby]

I have a columns that are GridTemplate columns with Custom Controls and Xamarin Forms Controls (Entry, etc.). If  I change the value of the Entry object, I fire an event and my SfDataGrid subscribces to this event change and attempts to Refresh the columns but fails. The columns do not resize.

The entry object itself seems like it is the same size.  I'm not sure if the Entry object itself has to resize and that in turn can trigger the column resizing.

My table column:

  GridTemplateColumn tableColumn = new GridTemplateColumn()

                        {

                            HeaderText = tableColumnDefinition.Header,

                            MappingName = mappingName,

                            LineBreakMode = LineBreakMode.WordWrap,

                            TextAlignment = TextAlignment.Center,

                            HeaderTextAlignment = TextAlignment.Center,

                            ColumnSizer = ColumnSizer.Auto

                        };

Hi Bobby,

Thanks for contacting Syncfusion support.

Your requirement can be achieved by refreshing the columns instead of refreshing the SfDataGrid on Value changed event of the Entry in GridTemplateColumn. We have prepared sample for the same.

Please refer the below code example,

 

[XAML]
…..
<syncfusion:GridTemplateColumn.CellTemplate> 

    <DataTemplate> 

                        <Grid>
<Entry Text="{Binding Name}" TextChanged="Entry_TextChanged"></Entry> 

                        </Grid> 

                    </DataTemplate> 

 </syncfusion:GridTemplateColumn.CellTemplate>
…..

[.CS]
…..
private void Entry_TextChanged(object sender, TextChangedEventArgs e) 

        { 

            if (e.OldTextValue != null && e.NewTextValue != null && e.NewTextValue != e.OldTextValue) 

            { 

//here grid.Columns[0] is the entry(Template column) column of SfDataGrid 

                grid.GridColumnSizer.ResetAutoWidth(grid.Columns[0]); 

                grid.GridColumnSizer.Refresh(); 

            } 

        }
