I too am having this problem:

<igDP:XamDataGrid DataSource="{Binding AvailableProjects}" AutoFit="True" Name="XamDataGrid1" GroupByAreaLocation="None">

<igDP:XamDataGrid.Resources>

<!-- This Style puts a CheckBox into the record selectors. -->

<Style TargetType="{x:Type igDP:RecordSelector}" BasedOn="{x:Null}">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type igDP:RecordSelector}">

HorizontalAlignment="Center"

VerticalAlignment="Center"

IsChecked="{Binding Path=DataItem.IsChecked, Mode=TwoWay}"

/>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

<!-- This Style puts a CheckBox into the header area above the record selectors. -->

<Style TargetType="{x:Type igDP:HeaderPrefixArea}" BasedOn="{x:Null}">

<Setter Property="Visibility" Value="Visible" />

<Setter Property="Template">

<ControlTemplate TargetType="{x:Type igDP:HeaderPrefixArea}">

<CheckBox

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</igDP:FieldLayout.Settings>

<igDP:FieldLayout.Fields>

<igDP:Field Name="Name" Label="Server Name" />

</igDP:FieldLayout.Fields>

<igDP:FieldSortDescription FieldName="Name" />

</igDP:FieldLayout.SortedFields>

</igDP:FieldLayout>

</igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>

Even though I have the AutoGenerate set to false, I see all the fields from my data, even down to Hierarchical items...

"The reason this happens is because the FieldLayout matching logic can't find a match and generates a new fieldlayout."

Is there any way to find out WHY a match cannot be found?   I get this behavior seemingly randomly and cannot figure out why this is sometimes happening (sometimes it happens sometimes not when running the application and showing different instances of the same grid).

No exceptions, no errors, no warnings.  Very difficult to debug!

Make sure all of the Names of all of the Fields you do specify match property names or column names of your data source exactly (case-sensitive). Otherwise, the FieldLayout you specified won't match and we will generate one that does, in this case without any fields since AutoGenerateFields is false.

I am facing an issue with the FieldLayoutSettings. Initially, I was getting extra columns which I had not specified in the fieldlayout. After reading the suggestions above, I moved the fieldlayout settings and made it global, for a xamdatagrid. But now, I am not able to see anything on the grid. I am new to infragistics and would really appreciate any help in this regard.

-->Hi,

I am facing an issue with the FieldLayoutSettings. Initially, I was getting extra columns which I had not specified in the fieldlayout. After reading the suggestions above, I moved the fieldlayout settings and made it global, for a xamdatagrid. But now, I am not able to see anything on the grid. I am new to infragistics and would really appreciate any help in this regard.

Thanks for this tip, I too was struggling with no fields being displayed, It turns out that if ANY of your fields don't match the data source then NO fields will be displayed and you get the blank grid.
