There is always one more blank line behind a grid in WPF

 <Grid>    <Dxg:gridcontrolName= "Griderrorsinfo"Autopopulatecolumns= "True"Showborder= "False"Showloadingpanel= "False"HorizontalAlignment= "Stretch"VerticalAlignment= "Stretch"allowcolumnmrufilterlist= "False"allowmrufilterlist= "False"Margin= "0,0,4,28"MouseDoubleClick= "Griderrorsinfo_mousedoubleclick">         <Dxg:GridControl.Columns>             <Dxg:gridcolumnName= "Num"FieldName= "Num"Header= "NUM"Width= "+"/>             <Dxg:gridcolumnName= "PageName"FieldName= "PageName"Header= "Name"Width= "Max"/>             <Dxg:gridcolumnName= "Errors"FieldName= "Errordetail"Width= "Auto"Header= "Megs"/>         </Dxg:GridControl.Columns>        <Dxg:GridControl.View>            <Dxg:tableviewName= "Errorviewlist"Autowidth= "True"Allowmovecolumntodroparea= "False"/>        </Dxg:GridControl.View>    </Dxg:gridcontrol></Grid>

<dxg:GridControl.View>  <dxg:tableview name= "errorviewlist"  autowidth= "True" Allowmovecolumntodroparea= "False"/></dxg:gridcontrol.view>
The most important of the above code is the above two sentences.

<DataGridAutoGenerateColumns= "False"Height= " the"HorizontalAlignment= "Left"Margin= "2,5,0,0"Name= "Datachartsingle"VerticalAlignment= "Top"Width= "225"isreadonly= "True">         <Datagrid.columns>             <DatagridtextcolumnHeader= "Varnumber"Binding="{Binding VarName}"Width= "The "Canusersort= "False"canuserresize= "True"/>                                                                                    <DatagridtextcolumnHeader= "Maxvar"Binding="{Binding Varmax}"Width= "$"Canusersort= "False"canuserresize= "True" />             <DatagridtextcolumnHeader= "Minvar"Binding="{Binding Varmin}"Width="*"Canusersort= "False"canuserresize= "True" />                                                                                </Datagrid.columns>                                                                   </DataGrid>

In the DataGrid is a good solution, just to the last column in the Width setting, set to Width= "*" The last column will be filled automatically.
