Data Binding

The ASPxVerticalGrid works only in bound mode. You can bind the vertical grid to any standard data source type: SqlDataSource, ObjectDataSource, XmlDataSource, AccessDataSource, and SiteMapDataSource.

Use the ASPxVerticalGrid.KeyFieldName property to set a data source’s key field name. The ASPxVerticalGrid.DataSourceID and ASPxVerticalGrid.DataSource properties specify the data source’s ID and the data source object, respectively.

ASPxVerticalGrid.DataSourceID:

<dx:ASPxVerticalGrid ID="ASPxVerticalGrid1" runat="server" DataSourceID="SqlDataSource1" 
    KeyFieldName="SupplierID" Width="70%" >
    <Rows>
        <dx:VerticalGridCategoryRow Caption="Contact Information">
            <Rows>
                <dx:VerticalGridTextRow FieldName="CompanyName" VisibleIndex="1" />
                <dx:VerticalGridTextRow FieldName="ContactName" VisibleIndex="2" />
            </Rows>
        </dx:VerticalGridCategoryRow>
        <dx:VerticalGridCategoryRow Caption="Address Information">
            <Rows>
                <dx:VerticalGridTextRow FieldName="Country" VisibleIndex="3" />
                <dx:VerticalGridTextRow FieldName="City" VisibleIndex="4" />
                <dx:VerticalGridTextRow FieldName="Address" VisibleIndex="5" />
            </Rows>
        </dx:VerticalGridCategoryRow>
    </Rows>
    <SettingsPager Mode="ShowPager" PageSize="3" />
</dx:ASPxVerticalGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;

  SelectCommand="SELECT [SupplierID], [ContactName], [Country], [City], [Address], [CompanyName] FROM [Suppliers]">
</asp:SqlDataSource>

ASPxVerticalGrid.DataSource:

SqlDataSource dataSource1 = new SqlDataSource(@"Provider=Microsoft.Jet.OLEDB.4.0;
    Data Source=|DataDirectory|\nwind.mdb;Persist Security Info=True", 
    "SELECT [SupplierID], [ContactName], [Country], [City], [Address], [CompanyName] FROM [Suppliers]");

Database Server Mode

The vertical grid supports database server mode. In this mode, the control loads only required items to the server memory and implements data-aware operations (for example, filtering) at the database level.

Unbound Rows

The control supports unbound rows that are not bound to any data source field. Use the CustomUnboundRowData event or specify the VerticalGridDataRow.UnboundExpression property to populate an unbound row with data.

VerticalGridDataRow.UnboundExpression:

<dx:ASPxVerticalGrid ID="VerticalGrid" runat="server" DataSourceID="SqlDataSource1" 
    KeyFieldName="SupplierID" >
    <Rows>
        <dx:VerticalGridTextRow FieldName="UnitPrice" VisibleIndex="1" />
        <dx:VerticalGridTextRow FieldName="Quantity" VisibleIndex="2" />
        <dx:VerticalGridTextRow FieldName="Discount" VisibleIndex="4" />
        <dx:VerticalGridTextRow FieldName="Total" UnboundType="Decimal" 
            UnboundExpression="UnitPrice*Quantity*(1-Discount)" />
    </Rows>
</dx:ASPxVerticalGrid>

ASPxVerticalGrid.CustomUnboundRowData event:

<dx:ASPxVerticalGrid ID="VerticalGrid" runat="server" DataSourceID="SqlDataSource1" 
    KeyFieldName="SupplierID" OnCustomUnboundRowData="VerticalGrid_CustomUnboundRowData" >
    <Rows>
        <dx:VerticalGridTextRow FieldName="UnitPrice" VisibleIndex="1" />
        <dx:VerticalGridTextRow FieldName="Quantity" VisibleIndex="2" />
        <dx:VerticalGridTextRow FieldName="Discount" VisibleIndex="4" />
        <dx:VerticalGridTextRow FieldName="Total" UnboundType="Decimal" />
    </Rows>
</dx:ASPxVerticalGrid>
protected void VerticalGrid_CustomUnboundRowData(object sender,
    ASPxVerticalGridRowDataEventArgs e) {
    if (e.Row.FieldName == "Total") {
        decimal unitPrice = Convert.ToDecimal(e.GetListSourceFieldValue("UnitPrice"));
        int quantity = Convert.ToInt32(e.GetListSourceFieldValue("Quantity"));
        decimal discount = Convert.ToDecimal(e.GetListSourceFieldValue("Discount"));
        e.Value = unitPrice * quantity * (1 - discount);
    }

Rows Management

The vertical grid displays data records as columns and data fields as rows.

Categories

The control allows you to group rows in categories (category rows). A category row (VerticalGridCategoryRow) stores its rows within the VerticalGridCategoryRow.Rows collection. Individual rows are objects of the VerticalGridDataRow, VerticalGridImageRow, VerticalGridHyperLinkRow types.

<dx:ASPxVerticalGrid ID="ASPxVerticalGrid1" runat="server" DataSourceID="SqlDataSource1" 
    KeyFieldName="SupplierID" Width="70%" >
    <Rows>
        <dx:VerticalGridCategoryRow Caption="Contact Information">
            <Rows>
                <dx:VerticalGridTextRow FieldName="CompanyName" VisibleIndex="1" />
                <dx:VerticalGridTextRow FieldName="ContactName" VisibleIndex="2" />
            </Rows>
        </dx:VerticalGridCategoryRow>
        <dx:VerticalGridCategoryRow Caption="Address Information">
            <Rows>
                <dx:VerticalGridTextRow FieldName="Country" VisibleIndex="3" />
                <dx:VerticalGridTextRow FieldName="City" VisibleIndex="4" />
                <dx:VerticalGridTextRow FieldName="Address" VisibleIndex="5" />
            </Rows>
        </dx:VerticalGridCategoryRow>
    </Rows>
    <SettingsPager Mode="ShowPager" PageSize="3"></SettingsPager>
</dx:ASPxVerticalGrid>

See demo

Fixed Rows

The vertical grid allows you to fix rows on the top side and display these rows onscreen when the rows’ total height exceeds the control height. Enable the vertical scrolling (Settings.VerticalScrollBarMode) and set a row’s Fixed property to true to fix the row.

<dx:ASPxVerticalGrid ID="ASPxVerticalGrid1" runat="server" DataSourceID="SqlDataSource1" 
    KeyFieldName="SupplierID" Width="70%" >
    <Rows>
        <dx:VerticalGridImageRow FieldName="PhotoUrl" Fixed="True" Caption="Photo"/>
        <dx:VerticalGridDataRow FieldName="Model" Fixed="True" />
        <!-- ... -->
    </Rows>
</dx:ASPxVerticalGrid>

See demo

Truncate Cell Text

The vertical grid can truncate cell (‘…’) values if they do not fit the cells’ width ( AllowEllipsisInText).

<dx:ASPxVerticalGrid ID="ASPxVerticalGrid1" runat="server" DataSourceID="SqlDataSource1" >
    <Rows>
        <!-- ... -->
    </Rows>
    <SettingsBehavior AllowEllipsisInText="True" />
</dx:ASPxVerticalGrid>

Data Edit

The vertical grid supports batch edit mode (Mode). In this mode, you can use in-line editors to edit control’s data. The vertical grid colors the modified cells in green. Deleted records are highlighted with gray and display the Recover command item.

<dx:ASPxVerticalGrid ID="ASPxVerticalGrid1" runat="server" >
    <Rows>
        <!-- ... -->
    </Rows>
    <SettingsEditing Mode="Batch" />
