MW,

Thats not really an option for me - reloading the whole data source would remarkably degrade performance as I'll be dealing with rather big collections. However, I still think there must be (or at the very least, should be ) a way to refresh a single record.

Cheers!

 Hi Joe

Thanks - once more - for your feedback. I'm aware of the automatic refresh (which makes perfectly sense), but in my case, none of this applies. It's just a converter of my style that would return a different value if it got re-evaluated. This is why I wanted to trigger a refresh manually. Is there no way to do this? 

Regarding the binding string: I don't understand how I could this make more flexible (without reverting to a cell value presenter).  As a short example:

<igDP:UnboundField BindingPath="{Binding Source={XXX}, Path=FirstName}" />

This binding expression will be resolved before it is being processed by the grid. So in case the binding returns "John" (which would be a value I'd like to see), WinGrid tries to bind the cell to a property named "John" rather than displaying the value.

Cheers,

Philipp 

CellValuePresenter myCellValuePresenter = CellValuePresenter.FromRecordAndField(myDataRecord, myField);

myCellValuePresenter.CoerceValue(CellValuePresenter.ValueProperty;

 Hello Joe

           <igDP:UnboundField Name="EditStatus"
                             Label=""
                             BindingPath="IsDirty">
            <igDP:Field.Settings>
              <igDP:FieldSettings AllowEdit="False"
                                  CellClickAction="SelectRecord"
                                  CellValuePresenterStyle="{StaticResource Grid_SimpleStatusCell}" />
            </igDP:Field.Settings>
          </igDP:UnboundField>

And this is my style:

  <Style x:Key="Grid_SimpleStatusCell"
         TargetType="{x:Type igDP:CellValuePresenter}">
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">
          <StackPanel Orientation="Horizontal">
            <Image Source="/Shared/Images/EditStatus/Changed.png"
                   VerticalAlignment="Center"
                   HorizontalAlignment="Left"
                   Width="16"
                   Height="16"
                   Margin="2,0,2,0"
                   Visibility="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Record.DataItem.IsDirty, Converter={StaticResource Control_BoolToVisibilityConverter}}" />
          </StackPanel>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>

The style sets the Visibility property of a status image using a converter along with the IsDirty property of the underlying data item. I used your snippet in the RecordUpdated event handler of the grid. At this moment, IsDirty has changed to true. However, the converter is not being invoked so I'm still stuck... Version, btw. is 7.2 RC

Thanks for your advice

Hi Naveen

   I see one problem with this approach though. Here is how I am using this.

if(e.Cell.Field.Name == "Fee")

{

DataRowView dv = e.Cell.Record.DataItem as DataRowView;

dv[

"Rate"] = Convert.ToDouble(e.Cell.Value) * .01;

e.Cell.Record.Visibility = Visibility.Collapsed;

e.Cell.DataPresenter.UpdateLayout();

e.Cell.Record.Visibility = Visibility.Visible;

}

After entering the value in the cell & hiting the Tab.. if the next column is a Editable it will not

go to edit mode & the horizontal scroll bar moves to the left.

Any idea how to solve these issues

Thanks

Hi Naveen

Hi, I was ably to solve the refresh records from using below code.    

public static void RedrawRecord(Record record_)
    {
      if (record_ != null)
      {
        // Force Xam Grid to redraw the record so that all syles can be re-applied.
        record_.Visibility = Visibility.Collapsed;
        var presenter = DataRecordPresenter.FromRecord(record_);
        if (presenter != null)
        {
          presenter.UpdateLayout();
        }
        record_.Visibility = Visibility.Visible;
      }
    }

Thanks,

Naveen

Hi

  Is there any solution for refresh problem. Even i have the same problem. I bind DataView (DataTable) to grid & on editing one column I need to re-calculate the value of other 2 columns. I am doing this at the DataRow level. So changes are not reflecting unless I go click on the other columns.

Thanks

Hi Can some one from infragistics comment on this? In addition to what I was doing earlier, I tried lot of options (below) but none causes the converter (which I am using to return color based on cell value) to be called. I was working with 9.1 builds. I am using latest sevice release 2010.2.20102.2045

                   var presenter = DataRecordPresenter.FromRecord(dataRecord);

                    var drCellArea = presenter.FindFirstChildByType<DataRecordCellArea>();
                    presenter.Visibility = Visibility.Collapsed;
                    presenter.Visibility = Visibility.Visible;
                    presenter.UpdateLayout();
                    presenter.InvalidateVisual();
                    drCellArea.Visibility = Visibility.Collapsed;
                    drCellArea.Visibility = Visibility.Visible;
                    drCellArea.UpdateLayout();
                    drCellArea.InvalidateVisual();
                    drCellArea.InvalidateProperty(Control.BackgroundProperty);
                    _grid.Visibility = Visibility.Collapsed;
                    _grid.Visibility = Visibility.Visible;
                    _grid.UpdateLayout();
                    _grid.InvalidateVisual();
