[Solved] Row index in currentcellchanged event

[vedant]

Hello,

 I have unique grid that is using SL lightweight datatable to populate cells in my RadGridView. I have to use it because my grid is dynamically created as per users preference about number of rows and columns.

 I have to bind blank rows initially and later user populate the data inside the cells using separate form view. When user select cell I have to fetch data from DB and populate that on form view. In order to do so I need to know row index and column index of selected cell.

 I can find column index easily but problem lies in row index because data in each cell is empty string and RadGridview is trying to lookup data based on datacontext as below: 

RadGridView1.Items.IndexOf(RadGridView1.CurrentCell)

here is my Xaml:
<telerik:RadGridView x:Name="RadGridView1" AutoExpandGroups="True" RowIndicatorVisibility="Collapsed" Grid.Row="1"
                 SelectionUnit="FullRow"    CurrentCellChanged="RadGridView1_CurrentCellChanged" SelectedCellsChanged="RadGridView1_SelectedCellsChanged"
                SelectionChanged="RadGridView1_SelectionChanged" />


Here is my codebehind:

    DataTable table = null;

    public MainPage()
    {
        InitializeComponent();
        Random rnd = new Random();

        table = new DataTable();

        for (int i = 0; i <= 5; i++)
        {
            var coln = "col " + i.ToString();
            table.Columns.Add(new DataColumn() { ColumnName = coln, DataType = typeof(string) });
        }

        for (var r = 0; r < 10; r++)
        {
            DataRow row = new DataRow();
            for (int c = 0; c <= 5; c++)
            {
                var coln = "col " + c.ToString();
                row[coln] = "Hello";
            }
            table.Rows.Add(row);
        }

        RadGridView1.ItemsSource = table.ToList();
    }

    private void RadGridView1_CurrentCellChanged(object sender, Telerik.Windows.Controls.GridViewCurrentCellChangedEventArgs e)
    {
        txtitems.Text = "you selected             Row   " + RadGridView1.Items.IndexOf(RadGridView1.CurrentCell)
                        + "        Column  " + e.NewCell.Column.DisplayIndex;
    }

    private void RadGridView1_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)
    {

    }

    private void RadGridView1_SelectedCellsChanged(object sender, Telerik.Windows.Controls.GridView.GridViewSelectedCellsChangedEventArgs e)
    {
        //txtitems.Text = "you selected             Row   " + RadGridView1.Items.IndexOf(e.AddedCells[0].Item)
        //               + "        Column  " + e.AddedCells[0].Column.DisplayIndex;
    }
}

I tried using both types of selectionunit (cell,fullrow), but none worked.
Is there anyway to get selected row index using some other event? I go through documentation but no help so far.
Thanks in advance.

Hello Vedant,

In this scenario RadGridView's items are not distinguishable from one another. In other words you are comparing equal strings. In order to tackle this problem, you might try defining your own type that wraps these values.
