ActiveTabIndex works as expected when tabs are always Visible, but when you set the Visible property to false, then back to true, the ActiveTabIndex does not work.

<TelerikTabStrip @bind-ActiveTabIndex="@ActiveTabIndex" PersistTabContent="true">

    <TabStripTab Title="@TabTitle" Visible="@IsTabVisible" >

..

IsTabVisible = true;

ActiveTabIndex = 1;

I encountered this behavior in both v2.30.0 and v3.2.0

At the moment, if I have many tabs, their titles go off the screen (or the container of the tab strip). I want that they don't stretch my layout, or they don't become invisible.

ADMIN EDIT

For the time being, there are two workarounds you can consider:

• adding a scrollbar to the tabs list:
  

  <style>
      /* sample settings for the parent of the tab strip to showcase how the rules below work */
      .tab-container {
          border: 1px solid red;
          width: 30%;
      }
      
      /* tab titles will now produce a scrollbar when too wide */
      .tab-container .k-tabstrip .k-tabstrip-items {
          flex-flow: inherit;
          max-width: 100%;
          overflow-x: auto;
          overflow-y: hidden;
      }
  
      /* just to showcase what happens when the content is wide - a separate scrollbar */
      .wide-content {
          background: yellow;
          width: 1200px;
      }
  </style>
  
  <div class="tab-container">
      <TelerikTabStrip>
          @foreach (var item in Enumerable.Range(1, 10))
          {
              <TabStripTab Title="@( $"Item {item}" )"><div class="wide-content">Content for item @item</div></TabStripTab>
          }
      </TelerikTabStrip>
  </div>

  
  
• making the tabs drop into multiple rows:

  <style>
      /* sample settings for the parent of the tab strip to showcase how the rules below work */
      .tab-container {
          border: 1px solid red;
          width: 30%;
      }
  
          /* tabs will wrap on more than one row if there are too many to fit */
          .tab-container .k-tabstrip .k-tabstrip-items {
              flex-wrap:wrap;
          }
  </style>
  
  <div class="tab-container">
      <TelerikTabStrip>
          @foreach (var item in Enumerable.Range(1, 10))
          {
              <TabStripTab Title="@( $"Item {item}" )"><div class="wide-content">Content for item @item</div></TabStripTab>
          }
      </TelerikTabStrip>
  </div>

I have four tabs in my tab strip, and the content in each tab is of varying width. The tab item resizes to the width of the content as it changes. I want to be able to set a fixed width for all the tabs so they don't expand and contract all the time.

===========

In the meantime, you can control the width of the TabStrip with some custom CSS. You can use its Class parameter to set a custom CSS class to the main wrapping container of the component and then apply the desired styles. Thus, you will be styling only this specific instance of the TabStrip and not all instances on the page/app (in case needed, you can of course add the same CSS class to all instances to have the same styles).

The sample below demonstrates the described approach. First instance of the TabStrip has the default setup, no additional styles added. Second instance has fixed width.

<TelerikTabStrip>
    <TabStripTab Title="First">
        First tab content. Go to the third tab to see the problem.
    </TabStripTab>
    <TabStripTab Title="Second tab heading longer than others">
        Second tab content. Go to the third tab to see the problem.
    </TabStripTab>
    <TabStripTab Title="Third">
        <div style="width: 2000px;">lorem ipsum</div>Third tab content.
    </TabStripTab>
</TelerikTabStrip>

<style>
    .tab-with-width {
        width: 600px;
    }
</style>

<TelerikTabStrip Class="tab-with-width">
    <TabStripTab Title="First">
        First tab content. Go to the third tab to see the behavior when the TapSrtrip has fixed width.
    </TabStripTab>
    <TabStripTab Title="Second tab heading longer than others">
        Second tab content. Go to the third tab to see the behavior when the TapSrtrip has fixed width.
    </TabStripTab>
    <TabStripTab Title="Third">
        <div style="width: 2000px;">lorem ipsum</div>Third tab content.
    </TabStripTab>
</TelerikTabStrip>

G'day

Just wondering if we can get an;

AllowDragReorder="true"

And added bonus; "OnDragReorder" event.

Similar to Telerik WPF;

Hi All,

I want to build a TabStip with many Tabs in multiline header like this:

, but now all headers located in a long line as shows below:

I could not found any attribute or a HeaderTemplate example to do this.

Can you please help me to do this?

I want to style my tab headers with something similar to this, but it does not compile:

 <h2>Telerik Tab Strip</h2>
    <TelerikTabStrip TabPosition="Telerik.Blazor.TabPosition.Top">
        <TabStripTab Class="WeirdTab" Title="First">
            First tab content.
        </TabStripTab>
        <TabStripTab Title="Second">
            Second tab content.
        </TabStripTab>
        <TabStripTab Title="Third">
            Third tab content.
        </TabStripTab>
    </TelerikTabStrip>
    <style>
        .WeirdTab {
            color: red;
        }
    </style>

While I can style the content of the tabs in the tabs themlselves (see below) I'd like to be able to style the headers too

<h2>Telerik Tab Strip</h2>
<TelerikTabStrip TabPosition="Telerik.Blazor.TabPosition.Top">
    <TabStripTab Title="First">
        <div class="WeirdTab">
            First tab content.
        </div>
    </TabStripTab>
    <TabStripTab Title="Second">
        Second tab content.
    </TabStripTab>
    <TabStripTab Title="Third">
        Third tab content.
    </TabStripTab>
</TelerikTabStrip>
<style>
    .WeirdTab {
        color: red;
    }
</style>

Support for adding Unicode characters (such as a warning sign, &#9888;) to the Title of tab strips.

Our scenario is we require specific setup to be done on each tab strip. We would like to ability to add an indicator next to the title of the tab to denote that setup is required.

The ActiveTabIndex parameter can take a value -1 to denote that no tab should be selected. This can plug into the current two-way binding as well.

<TelerikTabStrip TabPosition="TabPosition.Top">
    <TabStripTab Title="Sofia">

    </TabStripTab>
    <TabStripTab Title="London">

    </TabStripTab>
    <TabStripTab Title="Paris">
        <TelerikTabStrip TabPosition="TabPosition.Left">
            @foreach (var item in new string[] { "one", "two", "three" })
            {
                <TabStripTab Title="@item">x</TabStripTab>
            }
        </TelerikTabStrip>
    </TabStripTab>

</TelerikTabStrip>

Content inside the tabs is narrow and elements float next to each other. For example, charts or other divs have limited width (screenshot of the issue at the end of this post).

At the moment, you can't get the currently active tab with code, the Title property of the tabs is not public.

Ideally, something like this should work:

ADMIN EDIT: As of October 2023, the TabStrip supports getting and setting the active tab with the ActiveTabIndex parameter. This request was marked as Complete when we exposed a Title parameter for the TabStripTab component. Enhanced programmatic access to TabStrip tab IDs can be implemented as part of TabStrip dynamic (closable) tabs.
