RibbonTabCollection.AddCustomTab(Int32, String, String) Method

Adds a custom tab to the specified position in the ribbon.

Namespace: DevExpress.Blazor.Office

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

public IRibbonTab AddCustomTab(
    int index,
    string text,
    string categoryType = ""
)

Parameters

Name	Type	Description
index	Int32	The position where to insert the tab.
text	String	The tab text.

Optional Parameters

Name	Type	Default	Description
categoryType	String	String.Empty	The category type.

Returns

Type	Description
IRibbonTab	The inserted custom tab.

Remarks

Call an AddCustomTab method overload to create a custom tab and add it to the tab collection. You should add a group that contains items to the new tab to make it visible because the Rich Text Editor hides tabs that contain no visible and enabled items.

The code below inserts custom tabs and populates them with default groups.

<DxRichEdit CustomizeRibbon=OnCustomizeRibbon />

@code {
    void OnCustomizeRibbon(IRibbon ribbon) {
        // Clears the tab collection
        ribbon.Tabs.Clear();
        // Inserts a custom tab at the end of the tab collection
        IRibbonTab tableTab = ribbon.Tabs.AddCustomTab("Table");
        tableTab.Groups.Add(RichEditRibbonGroupNames.LayoutRowsAndColumns);
        tableTab.Groups.Add(RichEditRibbonGroupNames.DesignBordersAndShadings);
        // Inserts a custom tab at the first position in the tab collection
        IRibbonTab fileTab = ribbon.Tabs.AddCustomTab(0, "File");
        IBarGroup fileGroup = fileTab.Groups.Add(RichEditRibbonGroupNames.FileCommon);
    }
}
