Grid rendering issue
posted

We are using Xamgrids for displaying large number of rows, now the problem is with conditional formatting  and FormatString .

 

We have applied conditional formatting like negative value should be displayed in red   and format function of textcolumn to display a decimal up to certain decimal places

 

Now if I scroll from top to bottom, I can see negative numbers without red font and text columns without formatted decimal places data

 

This problem goes away if I move scroll bar and take particular row in and out of focus

 

Could you please explain the behavior described above and propose a solution?

    I think you grid is virtualized. Try to change the RecordContainerGenerationMode and test the scrolling

    <igWpf:XamDataGrid RecordContainerGenerationMode="LazyLoad"/>

    If the problem is solved with the above change then

          1. Remove the RecordContainerGenerationMode.

          2. Define a cellvaluepresenter style for that field.

                        <Style x:Key="CheckCellValuePresenterStyle" TargetType="{x:Type igDp:CellValuePresenter}" BasedOn="{StaticResource GeneralCvpStyle}">

                            <Setter Property="Template">

                                <Setter.Value>

                                    <ControlTemplate>

                                        <igEditors:XamNumericEditor Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Value}"

                                                                  Style="{DynamicResource ToggleCheckEditorStyle}" Margin="1,2,1,2" Padding="0"/>

                                    </ControlTemplate>

                                </Setter.Value>

                            </Setter>

                        </Style>

          3. Assign this cellvaluepresenter style to the field having the issue.

    I hope this will help

    Thanks,
