Hi there

 I was looking for a way to set the initial value of an unbound boolean field that is being displayed as a null value (I'd rather have it unchecked). As I didn't find a DefaultValue property or anything like it, I checked the archived forum for a solution and found this posting here:

 It provides a solution using an EditorStyle and a feedback from Infragistics that a related bug was going to be fixed within the next few weeks. The posting is eight months old, but I am having the exact same problem. Is this issue back in 7.2 Beta or there is a mistake on my side?

 <igDP:UnboundField Name="Checked"
                   Label=""
                   DataType="{x:Type sys:Boolean}">
  <igDP:UnboundField.Settings>
    <igDP:FieldSettings AllowEdit="True" EditorType="{x:Type igEditors:XamCheckEditor}">
      <igDP:FieldSettings.EditorStyle>
        <Style TargetType="{x:Type igEditors:XamCheckEditor}">
          <Setter Property="IsChecked"
                  Value="False" />
          <Setter Property="IsThreeState"
                  Value="False" />
        </Style>
      </igDP:FieldSettings.EditorStyle>
    </igDP:FieldSettings>
  </igDP:UnboundField.Settings>
</igDP:UnboundField>

...and this is how the above sample is being displayed:

Btw: The screenshot above also illustrates that the FieldLayoutSettings.DataRecordCellAreaGridTemplate seems to be buggy as well. I set up the grid with the following template:

            <ItemsPanelTemplate>
              <Grid>
                <Grid.ColumnDefinitions>
                  <ColumnDefinition Width="30" />
                  <ColumnDefinition Width="60" />
                  <ColumnDefinition Width="Auto" />
                </Grid.ColumnDefinitions>
              </Grid>
            </ItemsPanelTemplate>

 As you can clearly see, the last column in NOT properly resized. I cheated a little with the screenshot (the text was cut just after Language), but the result is the same.

Thanks for your advice
