Selecting Tabs via code

[dennis_dieckmann]

Hi,

mabe I'm to dumb, but I haven't figured out how I can select a tab with code.

In the Tabcontrol object from VS05 it's working like this: TabControl1.SelectTab(TabPage2)

How can I realize this with the Ribbonbar?

Thanks for your help.

You can use the TabStripElement.SelectedTab property of the RibbonBarElement, for example using the code below you can select the second tab (collection is zero based)

e.g.

// C#
radRibbonBar1.RibbonBarElement.TabStripElement.SelectedTab = radRibbonBar1.RibbonBarElement.TabStripElement.Items[1];

' VB.NET
radRibbonBar1.RibbonBarElement.TabStripElement.SelectedTab = radRibbonBar1.RibbonBarElement.TabStripElement.Items(1)

Hello Matt Stewart,

Indeed this works fine but it would be a good idea to check whether the index of the tab is  not out of range of the items collection boundaries.

e.g.

int index = 1;
if (( radRibbonBar1.RibbonBarElement.TabStripElement.Items.Count < index ) &&
(index >=0 ))
{
radRibbonBar1.RibbonBarElement.TabStripElement.SelectedTab = radRibbonBar1.RibbonBarElement.TabStripElement.Items[1];
}

Sure. This was just to serve the example. Bounds checking is always a good idea. And in your code the check should be reverse:

e.g.

instead of
radRibbonBar1.RibbonBarElement.TabStripElement.Items.Count < index

this one
index < radRibbonBar1.RibbonBarElement.TabStripElement.Items.Count

[Boyko Markov]

Hello Matt Stewart,
I confirm that the index should be smaller than the count of the items in the collection.
Thank you for the correction.

Hi,

thank you. This is working fine...

By the way:
There is a graphical bug when I do this!

When you click the tab on the ribbonbar, than everything is ok.
But if you select a tab with this code, than you have a line under the tab.

Please have a look on this picture:

I'm using Q4 2006 release.

Hi dennis_dieckmann,

We will investigate the problem which you have reported.
I suggest that you download the  Q1 release of RadControls for WinForms because the line below the TabStrip could have been a bug which is already fixed.
Thank you for the valuable feedback.


All the best,

Maybe you can try suspending the Form Layout until the changes are made? This is similar to what telerik serialization code does in the Form.Designer.cs files, so it may work around the redrawing issue:

            this.SuspendLayout();
            radRibbonBar1.RibbonBarElement.TabStripElement.SelectedTab = radRibbonBar1.RibbonBarElement.TabStripElement.Items[1];
            this.ResumeLayout(false);

Isn't working in my Project.

Whatever.. this line isn't that much important to me.

It will be great if you cant select the tab by name or Key. Because if you canhe orders the code is broke.

Thanks

Hi Leonardo Prada,

We agree with you that it would be a nice feature to select a tab by name and we will add it to our To Do list for the scheduled SP2 release.
If you have any other interesting ideas about adding new features and functionality to our controls please do not hesitate to share them with us.

Best wishes,

What if the tab is in a contextual group?

I can display the contextual tab group, but how do I auto-select it?

	if (sender is ProdMasterTab)
	{
	// hide all tab groups
	foreach (ContextualTabGroup contextualTabGroup in RadRibbonBar.ContextualTabGroups)
	{
	contextualTabGroup.Visibility=ElementVisibility.Collapsed;
	}
	foreach (ContextualTabGroup contextualTabGroup in RadRibbonBar.ContextualTabGroups)
	{
	if ((string)contextualTabGroup.Tag=="ProdMaster")
	{
	contextualTabGroup.Visibility=ElementVisibility.Visible;
	//TabStripElement.SelectedTab =                this.radRibbonBar1.RibbonBarElement.TabStripElement.Items[0];
	//contextualTabGroup.
	//RadRibbonBar.SelectedCommandTab=contextualTabGroup.TabItems[0];// =contextualTabGroup.TabItems[0];
	}
	}
	}

Hi Dennis,

If I understand you correctly, you want to "activate" the contextual group as if it was clicked. The contextual groups in RadRibbonBar do not support this functionality. However when a contextual tab group is clicked the first tab in it will get selected.

Hope that helps.

Why do they not support that functionality? Seems obvious to me.

It also happens in Office 2007, so if you were mimicking the Office UI, then why not mimick this feature?

[Jordan]

Hello Dennis,

The RadRibbonBar was designed as per the early drafts of the Office 2007 UI guidelines from Microsoft - this is reason why this difference exists. We are considering some improvements in RadRibbonBar, including the one discussed here, but we cannot give you a specific timeframe at the moment.

As for the auto activate feature of contextual tab groups - thank you for pointing this out. We have added it in our TODO list for the Q2 2007 release.

Hi,

Has this auto activate of Contextual Groups been added yet? I'm keen to use it to help my users out with their/my usability issues.

[Jordan]

Hello DukeVideo,

Unfortunately, this feature was dropped from the 2007 Q2 release because of some other high priority tasks.
This feature is still on our TODO list and will be implemented as soon as possible, but we cannot give a specific timeframe at the moment.

Contact us again if you have additional questions.

For those that wanted to select tabs by name (like I needed to), here is some code. It's simple, but it works.

foreach (RadItem ri in radRibbonBar1.RibbonBarElement.TabStripElement.Items)
{
    if (ri.Text == "TabTextValue")
    {
        radRibbonBar1.RibbonBarElement.TabStripElement.SelectedTab = ri;
        break;
    }
}
