Required Background

The following topics are prerequisites to understanding this topic:

Topic	Purpose
Getting Started With XamDataGrid	This topic provides basic steps required for adding the XamDataGrid control to your view and populating it with sample data.
Sample Sales Person	This resource topic provides implementation of sample data that you can use a data source for the XamDataGrid control.

Overview:

Horizontal Scrolling allows you to include content on the XamDataGrid control that would otherwise exceed the actual width of the XamDataGrid control; this is made possible by including a Horizontal Scrolling feature.

Horizontal scrolling behavior is virtually identical to the vertical scrolling ability that is used to “scroll down” a page to view content, (for example, such as rows) that is present below the current viewable area.

Scrolling On Auto-Generated Columns

This example assigns an instance of the ColumnWidth class to the DefaultColumnWidth property of all auto-generated columns in the XamDataGrid control.

In XAML:

<ig:XamDataGrid x:Name="DataGrid" AutoGenerateColumns="True" DefaultColumnWidth="300" />

In C#:

var columnWidth = new ColumnWidth { IsStarSized = false, Value = 300 };

DataGrid.AutoGenerateColumns = true;
DataGrid.DefaultColumnWidth = columnWidth;

Scrolling On Predefined Columns

The following example demonstrates how to implement horizontal sorting on grid columns that you defined in the Columns collection of XamDataGrid control. In this scenario, the XamDataGrid control is bound to data containing three Column objects: FirstName, LastName, and Territory; which have been manually defined and have been given a sufficient width such that they effectively exceed the visible width of the XamDataGrid control.

This example assigns an instance of the ColumnWidth class to all manually defined Column objects in the XamDataGrid control using their Width {ApiMebmer}.

Note	Note You can set the column width to any other types of columns in XamDataGrid control, the same way it is demonstrated with TextColumn object.

In XAML:

<ig:XamDataGrid x:Name="DataGrid" AutoGenerateColumns="False" >
    <ig:XamDataGrid.Columns>
        <ig:TextColumn HeaderText="FirstName" PropertyPath="FirstName" Width="300" />
        <ig:TextColumn HeaderText="LastName" PropertyPath="LastName" Width="300" />
        <ig:TextColumn HeaderText="Territory" PropertyPath="Territory" Width="300"  />
    </ig:XamDataGrid.Columns>
</ig:XamDataGrid>

In C#:

TextColumn column1 = new TextColumn();
column1.PropertyPath = "FirstName";
column1.HeaderText = "FirstName";

TextColumn column2 = new TextColumn();
column2.PropertyPath = "LastName";
column2.HeaderText = "LastName";

TextColumn column3 = new TextColumn();
column3.PropertyPath = "Territory";
column3.HeaderText = "Territory";

var columnWidth = new ColumnWidth { IsStarSized = false, Value = 300 };

column1.Width = columnWidth;
column2.Width = columnWidth;
column3.Width = columnWidth;

DataGrid.AutoGenerateColumns = false;
DataGrid.Columns.Add(column1);
DataGrid.Columns.Add(column2);
DataGrid.Columns.Add(column3);

Conclusion

Both code examples will enable horizontal scrolling of columns, once you start scrolling left or right within the XamDataGrid control.
