How to determine the actual width of the gridview?

[Ludwig]

Hi,

I have a grid like:

<telerik:RadGridView Name="patientsGridView" SelectionMode="Extended" ItemsSource="{Binding Patients}" SelectedItem="{Binding SelectedPatient}" AutoGenerateColumns="False" IsReadOnly="True" MouseDoubleClick="patientsGridView_MouseDoubleClick" RowIndicatorVisibility="Collapsed" SelectionChanged="patientsGridView_SelectionChanged" GroupPanelStyle="{DynamicResource GridViewGroupPanelStyle1}" >                      

    <telerik:RadGridView.Columns>

                            <!-- IsActiveGroup -->
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding IsActiveGroup}" >
                                <telerik:GridViewDataColumn.FilteringControl>
                                    <GridView:FilteringControl Style="{DynamicResource FilteringControlStyle}"/>
                                </telerik:GridViewDataColumn.FilteringControl>
                                <telerik:GridViewDataColumn.Header>
                                    <TextBlock Text="  " ToolTip="{lex:LocText S3.ParametersUE.PatientManagement:UIStrings:PatientListView_PatientGridColumnIsActiveToolTip}"/>
                                </telerik:GridViewDataColumn.Header>
                                <telerik:GridViewDataColumn.CellTemplate>
                                    <DataTemplate>
                                        <Image Source="{Binding Path=IsActiveImageSource, Converter={StaticResource imgConverter}}" Stretch="UniformToFill" RenderOptions.BitmapScalingMode="HighQuality" Width="20" Height="20" ToolTip="{Binding IsActiveGroup}" />
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellTemplate>
                            </telerik:GridViewDataColumn>   
 <!-- HasWarningGroup -->
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding HasWarningGroup}" >
                                <telerik:GridViewDataColumn.FilteringControl>
                                    <GridView:FilteringControl Style="{DynamicResource FilteringControlStyle}"/>
                                </telerik:GridViewDataColumn.FilteringControl>
                                <telerik:GridViewDataColumn.Header>
                                    <TextBlock Text="  " ToolTip="{lex:LocText S3.ParametersUE.PatientManagement:UIStrings:PatientListView_PatientGridColumnHasWarningToolTip}"/>
                                </telerik:GridViewDataColumn.Header>
                                <telerik:GridViewDataColumn.CellTemplate>
                                    <DataTemplate>
                                        <Image Source="{Binding Path=HasWarningImageSource, Converter={StaticResource imgConverter}}" Stretch="UniformToFill" RenderOptions.BitmapScalingMode="HighQuality" Width="20" Height="20" ToolTip="{Binding HasWarningGroup}" />
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellTemplate>
                            </telerik:GridViewDataColumn>


etc...

I need the width of the grid - but ActualWidth is always 0. How can I get the width of the grid?

Hi Ludwig,

This sounds quite strange. Are you sure that the RadGridView is attached to the visual tree at the moment you are checking its width? If you want to determine its width as soon as possible you may try doing it on its Loaded event. You might want to see the attached project for more extensive information.
