Greetings, how can I tell the RadTreeView to ignore accent when applying Filter.
the content of my RadTreeView there are nodes that have accents in the text, for example Balance Calculation, and if I search without an accent it does not search for me
How do I tell the TreeView Filter to ignore accents?
Use:
Visual Studio 2022
.Net Framework 4.8
Telerik WinForms 22.1.222.0

Hello Danny,
Thank you for the provided details.
In this case, you could consider using custom filtering. You can create a custom method that accepts RadTreeNode and uses the string.Compare() method you could ignore the accent and compare the strings. More information can be found in the Custom Filtering help article in our documentation. Here is a sample code that demonstrates what I have in mind.
public RadForm1()
{
InitializeComponent();
radTreeView1.TreeViewElement.FilterPredicate = FilterNode;
}
private bool FilterNode(RadTreeNode node)
{
var filterText = this.radTreeView1.Filter;
var result = string.Compare(node.Text, filterText.ToString(), CultureInfo.CurrentCulture, CompareOptions.IgnoreNonSpace);
if (result == 0)
{
// the strings are equal
return true;
}
return false;
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radTreeView1.Filter = "Sorina";
}
I am also attaching the sample project which I used to test your case.
Regards,
