FixedFieldUIType Property

Determines the type of ui displayed to allow the end user to change the FixedLocation of the fields.
Syntax
'Declaration
 
Public Property FixedFieldUIType As FixedFieldUIType
public FixedFieldUIType FixedFieldUIType {get; set;}
Remarks

Note: Even if no ui is displayed, the end user may change the FixedLocation of a field by dragging a column into or out of the fixed area assuming that FieldItem.AllowFixingResolved allows the state to be changed and the field allows moving.

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" />
