AllowFixing Property (FieldSettings)

Determines if the end user should be allowed to change the fixed state of the field and to which edges the field may be fixed.
Syntax
'Declaration
 
Public Property AllowFixing As AllowFieldFixing
public AllowFieldFixing AllowFixing {get; set;}
Example
The following sample demonstrates how to enable fixing for fields. It uses the FixedLocation to determine the initial fixed position of a specific field and prevents one of them from being unfixed.

        <igDP:XamDataGrid BindToSampleData="True">
            <igDP:XamDataGrid.FieldSettings>
                <!-- Enable fixing for all fields -->
                <igDP:FieldSettings AllowFixing="NearOrFar" />
            </igDP:XamDataGrid.FieldSettings>
            <igDP:XamDataGrid.FieldLayouts>
                <igDP:FieldLayout>
                    <igDP:FieldLayout.Fields>
                        <!-- Initialize some fields so they start out fixed -->
                        <igDP:Field Name="name" FixedLocation="FixedToNearEdge" />
                        
                        <!-- fix this to the right and prevent the user from changing it -->
                        <igDP:Field Name="department" FixedLocation="FixedToFarEdge">
                            <igDP:Field.Settings>
                                <igDP:FieldSettings AllowFixing="No" />
                            </igDP:Field.Settings>
                        </igDP:Field>
                    </igDP:FieldLayout.Fields>
                </igDP:FieldLayout>
            </igDP:XamDataGrid.FieldLayouts>
        </igDP:XamDataGrid>        <igDP:XamDataGrid BindToSampleData="True">
            <igDP:XamDataGrid.FieldSettings>
                <!-- Enable fixing for all fields -->
                <igDP:FieldSettings AllowFixing="NearOrFar" />
            </igDP:XamDataGrid.FieldSettings>

            <!-- The FixedFieldUIType determines what ui is presented 
                to the end user to change the fixed location of a field -->
            <igDP:XamDataGrid.FieldLayoutSettings>
                <igDP:FieldLayoutSettings FixedFieldUIType="ButtonAndSplitter" />
            </igDP:XamDataGrid.FieldLayoutSettings>
            
            <igDP:XamDataGrid.FieldLayouts>
                <igDP:FieldLayout>
                    <igDP:FieldLayout.Fields>

                        <igDP:Field Name="department" FixedLocation="FixedToFarEdge">
                            <igDP:Field.Settings>
                                <igDP:FieldSettings AllowFixing="No" />
                            </igDP:Field.Settings>
                        </igDP:Field>
                    </igDP:FieldLayout.Fields>
                </igDP:FieldLayout>
            </igDP:XamDataGrid.FieldLayouts>
