[Solved] Automatically setting IsBreak for Multiline RadTabStrip

[Stephen Wright]

I created an Extension method that will set the page break of a RadTabStrip for visible tabs only and then split the rows in half.  I have a situation where some of the tabs will be visible during certain page views. 

so in your code for the page_load, you would just call:

RadTabStrip1.FormatMultiLineTabs(False);

If you have any refactorings  or improvements for this snippet, I'd be interested to see it.
Enjoy!

C#:

using Telerik.Web.UI;
using System.Runtime.ComplierServices;

public class RadTabStripExtensions
{

    [Extension()]
    public void FormatMultiLineTabs(ref RadTabStrip tab, bool ForceMultiLine)
    {
        int intTabCount = 0;
        foreach (RadTab objTab in tab.Tabs) {
            if (objTab.Visible)
            {
                intTabCount += 1;
            }
        }
        if (ForceMultiLine || intTabCount >= 8) // this can be changed to the line break number
        {
            int intTabBreakIndex = intTabCount / 2 - 1;
            if (intTabCount % 2 == 1)
            {
                intTabBreakIndex += 1;
            }
            tab.AddTabBreakToVisibleTabIndex(intTabBreakIndex);
        }
    }

    [Extension()]
    public void AddTabBreakToVisibleTabIndex(ref RadTabStrip tab, int VisibleIndexBreak)
    {
        int intIndex = 0;
        foreach (RadTab objTab in tab.Tabs) {
            if (objTab.Visible)
            {
                if (intIndex == VisibleIndexBreak)
                {
                    objTab.IsBreak = true;
                }
                intIndex += 1;
            }
        }
    }

}

VB:

Imports Telerik.Web.UI
Imports System.Runtime.CompilerServices

Public Module RadTabStripExtensions

    <Extension()> _
    Public Sub FormatMultiLineTabs(ByRef tab As RadTabStrip, ByVal ForceMultiLine As Boolean)
        Dim intTabCount As Integer = 0
        For Each objTab As RadTab In tab.Tabs
            If objTab.Visible Then
                intTabCount += 1
            End If
        Next
        If ForceMultiLine OrElse intTabCount >= 8 Then 'this can be changed to the line break number
            Dim intTabBreakIndex As Integer = intTabCount \ 2 - 1
            If intTabCount Mod 2 = 1 Then
                intTabBreakIndex += 1
            End If
            tab.AddTabBreakToVisibleTabIndex(intTabBreakIndex)
        End If
    End Sub

    <Extension()> _
    Public Sub AddTabBreakToVisibleTabIndex(ByRef tab As RadTabStrip, ByVal VisibleIndexBreak As Integer)
        Dim intIndex As Integer = 0
        For Each objTab As RadTab In tab.Tabs
            If objTab.Visible Then
                If intIndex = VisibleIndexBreak Then
                    objTab.IsBreak = True
                End If
                intIndex += 1
            End If
        Next
    End Sub

End Module

hi

i tried to run the same snippet and its giving me errors at tab.Visible and tab.Isbreak.

Can you provide a sample.

my requirement is similar to have multi lined tabs.

Thanks again,
