WebColumnBase.Visible Property

Specifies whether the column is visible.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

[DefaultValue(true)]
public bool Visible { get; set; }

VB.NET

<DefaultValue(True)>
Public Property Visible As Boolean

Property Value

Type	Default	Description
Boolean	true	true to show the column; otherwise, false.

Remarks

A column’s Visible property specifies whether this column is visible. To define the column’s position among visible columns, use the VisibleIndex property.

The false value of the Visible property sets the VisibleIndex property to -1. If you change the VisibleIndex property value to non-negative, a web control sets the Visible property to true.

ASPX

<dx:ASPxGridView ID="grid" runat="server" KeyFieldName="CustomerID">
    <Columns>
        <dx:GridViewDataTextColumn FieldName="ContactName" VisibleIndex="1" />
        <dx:GridViewDataTextColumn FieldName="CompanyName" VisibleIndex="0" />
        <dx:GridViewDataTextColumn FieldName="City" VisibleIndex="3" />
        <dx:GridViewDataTextColumn FieldName="Region" Visible="false" />
        <dx:GridViewDataTextColumn FieldName="Country" VisibleIndex="2" />
