NuGet Package: DevExpress.Web

Declaration

public event ASPxGridViewTableRowEventHandler HtmlRowPrepared

VB.NET

Public Event HtmlRowPrepared As ASPxGridViewTableRowEventHandler

Event Data

The HtmlRowPrepared event's data class is ASPxGridViewTableRowEventArgs. The following properties provide information specific to this event:

Property	Description
KeyValue	Gets an object that uniquely identifies the row.
Row	Gets the processed row.
RowType	Gets the processed row’s type.
VisibleIndex	Gets the visible index of the data row. Inherited from ASPxGridViewItemEventArgs.

The event data class exposes the following methods:

Method	Description
GetValue(String)	Returns the value of the specified cell within the processed row.

Remarks

The HtmlRowPrepared event is raised for each grid row (data row, group row, etc.) within the ASPxGridView. You can handle this event to change the style settings of individual rows.

Note

During export operations, the Grid View control ignores appearance settings specified in the HtmlRowPrepared event handler. Refer to the following topic for more information on how to customize exported elements in different export modes: Export Modes.

The HtmlRowPrepared and ASPxGridView.HtmlRowCreated events are not fired for the grid’s column header row and title row. So, the ASPxGridViewTableRowEventArgs.RowType property is never set to GridViewRowType.Title or GridViewRowType.Header within these event arguments.

In this example, the HtmlRowPrepared event is handled to highlight the products whose price is less than $20 or more than $50.

C#

    protected void ASPxGridView1_HtmlRowPrepared(object sender, DevExpress.Web.ASPxGridViewTableRowEventArgs e) {
        if (e.RowType != GridViewRowType.Data) return;
        int price = Convert.ToInt32(e.GetValue("UnitPrice"));
        if (price < 20)
            e.Row.BackColor = System.Drawing.Color.LightCyan; 
        if (price > 50)
            e.Row.ForeColor = System.Drawing.Color.DarkRed;
    }

VB.NET

    End If
    Dim price As Integer = Convert.ToInt32(e.GetValue("UnitPrice"))
