What I must to do for receiving RecordPresenter, that is not null?

Hi, Joe

I have for example three XamDataGrids: xamDataGrid1, xamDataGrid2, xamDataGrid3.

<igDP:XamDataGrid x:Name="xamDataGrid1"

GroupByAreaLocation="AboveDataArea"

DataSource="{Binding Path=DataSource1, ElementName=UserControl}"> <igDP:XamDataGrid.FieldSettings>

<igDP:FieldSettings

AllowEdit="False"

ExpandableFieldRecordExpansionMode="ExpandAlways"

ExpandableFieldRecordHeaderDisplayMode="NeverDisplayHeader" />

</igDP:XamDataGrid.FieldSettings>

<igDP:XamDataGrid.FieldLayoutSettings>

<igDP:FieldLayoutSettings HighlightAlternateRecords="True" />

</igDP:XamDataGrid.FieldLayoutSettings> <igDP:XamDataGrid.FieldLayouts>

<igDP:FieldLayout Key="FieldLayout11">

...

</igDP:FieldLayout>

</igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>

<igDP:XamDataGrid x:Name="xamDataGrid2"

GroupByAreaLocation="AboveDataArea"

DataSource="{Binding Path=DataSource2, ElementName=UserControl}"> <igDP:XamDataGrid.FieldSettings>

<igDP:FieldSettings

AllowEdit="False"

ExpandableFieldRecordExpansionMode="ExpandAlways"

ExpandableFieldRecordHeaderDisplayMode="NeverDisplayHeader" />

</igDP:XamDataGrid.FieldSettings>

<igDP:XamDataGrid.FieldLayoutSettings>

<igDP:FieldLayoutSettings HighlightAlternateRecords="True" />

</igDP:XamDataGrid.FieldLayoutSettings> <igDP:XamDataGrid.FieldLayouts>

<igDP:FieldLayout Key="FieldLayout12">

...

</igDP:FieldLayout >

</igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>

<igDP:XamDataGrid x:Name="xamDataGrid3"

GroupByAreaLocation="AboveDataArea"

DataSource="{Binding Path=DataSource3, ElementName=UserControl}"> <igDP:XamDataGrid.FieldSettings>

<igDP:FieldSettings

AllowEdit="False"

ExpandableFieldRecordExpansionMode="ExpandAlways"

ExpandableFieldRecordHeaderDisplayMode="NeverDisplayHeader" />

</igDP:XamDataGrid.FieldSettings>

<igDP:XamDataGrid.FieldLayoutSettings>

<igDP:FieldLayoutSettings HighlightAlternateRecords="True" />

</igDP:XamDataGrid.FieldLayoutSettings> <igDP:XamDataGrid.FieldLayouts>

<igDP:FieldLayout Key="FieldLayout13">

...

</igDP:FieldLayout > </igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>

So I’d like to do somethig with this grids, for example this:public void MainActions()

{

(xamDataGrid1.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsActive = true;

(xamDataGrid2.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsActive = true;

(xamDataGrid3.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsActive = true;

(xamDataGrid1.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsSelected = true;

(xamDataGrid2.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsSelected = true;(xamDataGrid3.FieldLayouts[0].DataPresenter.Records[0] as DataRecord).IsSelected = true;

DoSomethigInGrid(xamDataGrid1);

DoSomethigInGrid(xamDataGrid2);

DoSomethigInGrid(xamDataGrid3);

if (xamDataGrid1.ActiveRecord != null)

{

DataRecordPresenter drp1 = DataRecordPresenter.FromRecord(xamDataGrid1.ActiveRecord) as DataRecordPresenter;

}

if (xamDataGrid2.ActiveRecord != null)

{

DataRecordPresenter drp2 = DataRecordPresenter.FromRecord(xamDataGrid2.ActiveRecord) as DataRecordPresenter;

}

if (xamDataGrid3.ActiveRecord != null)

{

DataRecordPresenter drp3 = DataRecordPresenter.FromRecord(xamDataGrid3.ActiveRecord) as DataRecordPresenter;

}

//so in this procedure drp1 != null

//so in this procedure drp2 != null

//so in this procedure drp3 != null

// when ActiveRecords != null

}

private void DoSomethigInGrid(XamDataGrid xdg)

{

if (xdg.FieldLayouts.Count > 0 &&

xdg.FieldLayouts[0].DataPresenter.Records.Count > 0 &&

xdg.ActiveRecord != null)

{

DataRecordPresenter drp =

DataRecordPresenter.FromRecord(xdg.ActiveRecord) as DataRecordPresenter;

//so in this procedure drp=null

}

So in procedure MainActions() all DataRecordPresenter drps != null.So in procedure DoSomethigInGrid() DataRecordPresenter drp = null always.
