How to Search and Select the Record in WPF and UWP TreeGrid?

This example illustrates how to search and select the record in WPF TreeGrid and UWP TreeGrid (SfTreeGrid).

For WPF:

You can search and select a record in TreeGrid based on the searched text using the TextChanged event of TextBox.

private void TextBox_TextChanged(object sender, System.Windows.Controls.TextChangedEventArgs e)
{
    var textBox = sender as TextBox;
    var treeGrid = this.AssociatedObject.treeGrid;
    if (textBox.Text == "")
        treeGrid.SelectedItems.Clear();

    for (int i = 0; i < treeGrid.View.Nodes.Count; i++)
    {
        if (Provider == null)
            Provider = treeGrid.View.GetPropertyAccessProvider();

        if (treeGrid.View.Nodes[i].HasChildNodes && treeGrid.View.Nodes[i].ChildNodes.Count == 0)
        {
            treeGrid.BeginInit();
            treeGrid.ExpandNode(treeGrid.View.Nodes[i]);
            treeGrid.CollapseNode(treeGrid.View.Nodes[i]);
            treeGrid.EndInit();
        }
        else if (treeGrid.View.Nodes[i].HasChildNodes)
        {                    
            dataRow = (treeGrid.View.Nodes[i].Item as EmployeeInfo);
            FindMatchText(dataRow);
            GetChildNodes(treeGrid.View.Nodes[i]);
        }
        else
        {
            dataRow=(treeGrid.View.Nodes[i].Item as EmployeeInfo);
            FindMatchText(dataRow);
        }
    }
}

For UWP:

You can search and select a record in TreeGrid based on the searched text using the TextChanged event of TextBox.

private void Textbox_TextChanged(object sender, TextChangedEventArgs e)
{
    var textBox = sender as TextBox;
            
    if (textBox.Text == "")
        treeGrid.SelectedItems.Clear();

    for (int i = 0; i < treeGrid.View.Nodes.Count; i++)
    {
        if (Provider == null)
            Provider = treeGrid.View.GetPropertyAccessProvider();

        if (treeGrid.View.Nodes[i].HasChildNodes && treeGrid.View.Nodes[i].ChildNodes.Count == 0)
        {
            treeGrid.ExpandNode(treeGrid.View.Nodes[i]);
            treeGrid.CollapseNode(treeGrid.View.Nodes[i]);
        }
        else if (treeGrid.View.Nodes[i].HasChildNodes)
        {
            dataRow = (treeGrid.View.Nodes[i].Item as PersonInfo);
            FindMatchText(dataRow);
            GetChildNodes(treeGrid.View.Nodes[i]);
        }
        else
        {
            dataRow = (treeGrid.View.Nodes[i].Item as PersonInfo);
            FindMatchText(dataRow);
        }
    }
}
