How to reset Breadcrumb

[Nadine]

Hi,

is it possible to reset the text of a breadcrumb (databind on treeview)?

.ResetText does not work...

A workaround could be to perform a click on the treeview programatically to get an update of the breadcrumb, but this doesn't seem to work either. I tried radtreeview.RootElement.PerformClick() without success.

A Clear-Method for the breadcrumb should be helpful for the beginning, but I didn't found one.

Best regards

Nadine

Hello Nadine,

Thank you for writing and pointing this issue out. The RefreshText method does not work because it is not implemented in the RadBreadCrumb. I have fixed the bread crumb and now it can be refreshed by calling UpdateBreadCrumb(RadTreeNode n). The argument should, in your case, be the SelectedNode of the RadTreeView. This fix will be included in the Q1 2009 SP1, which will be available in about a month.
Please write back if you have other questions.

I ended up hiding and showing the breadcrumb in order to give the appearance of "clearing" it.   So, there is no way to have the breadcrumb be cleared out if you clear out the associated tree view?

Hi George,

Thank you for writing.

Currently there is no way to detach the bread crumb from a tree view. This is on our to do list and will be implemented in the future.

Please write again if you have other questions.

Has this been implemented?

Hello Steve,

Thank you for writing.  

In order to clear RadBreadCrumb it is necessary to set the DefaultTreeView property to null:

this.radBreadCrumb1.DefaultTreeView = null;

I hope this information helps. Should you have further questions I would be glad to help.

This worked but when I populate my treeview again and set the breadcrumb property, it shows the previously selected treeview node even though nothing is selected.

I had tried clearing the treeview selected nodes but got an error. I later found out I needed to unbind the breadcrumb first. In case anyone else is having the same issue, I finally figured it out using the code below. The order of statements is important.

// clear/unbind controls before getting data
BreadCrumb.DefaultTreeView = null;
TreeView.ClearSelection();
TreeView.Nodes.Refresh();
// get the data and rebind controls
//var myList = new List<myData>() ...
TreeView.DataSource = myList;
BreadCrumb.DefaultTreeView = TreeView;
