MVCxTab.SetTabTemplateContent(Action<TabControlTemplateContainer>) Method

Allows you to set a template for the current tab’s content.

Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v23.2.dll

NuGet Package: DevExpress.Web.Mvc5

Declaration

C#

public void SetTabTemplateContent(
    Action<TabControlTemplateContainer> contentMethod
)

VB.NET

Public Sub SetTabTemplateContent(
    contentMethod As Action(Of TabControlTemplateContainer)
)

Parameters

Name	Type	Description
contentMethod	Action<TabControlTemplateContainer>	A method to which a template content rendering is delegated.

Remarks

If the active tab template is not specified, the SetTabTemplateContent method is raised twice: once for the inactive tab state, and once for the active state. This can cause the following exception: “An extension with X name already rendered” because a control in the template is rendered twice with the same name. You can resolve this issue in the following ways:

• Use the SetActiveTabTemplateContent method in addition to the SetTabTemplateContent method to specify a template for the active tab state.
• Create a unique name based on the Active argument available in the SetTabTemplateContent method.

  tabsettings.TabPages.Add(c => {
      c.Name = "Tab1";
      c.Text = "First";
      c.SetTabTemplateContent(headsettings => {
          string isActive = headsettings.Active ? "active" : string.Empty;
          Html.DevExpress().Image(imgsettings => {
              imgsettings.Name = "img1_" + isActive;
              imgsettings.Properties.EmptyImage.IconID = IconID.NavigationHome16x16office2013;
              imgsettings.ControlStyle.CssClass = "TabHeadImage";
          }).Render();
      }
  }
