如何从DataGrid中的选定行获取值？

Question

All I found is about DataGridView and have tried some event handlers and I'm stuck now.

Assuming I have DataGrid like below :

DataTable dt = new DataTable();
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Code", typeof(String));
dt.Columns.Add("Name", typeof(String));
gridData.DataSource = dt;

How I capture onClick event with SelectedRows["ID"]

This solution works for DataGridView but not with DataGrid.

Answer 1

You can use the property SelectedCells of that DataGrid. That property returns to you an collection of current selected cells and you can iterate over that collection using a foreach loop

Supposing that you want to get the values as strings, this code can be usefull:

// This is the list where the values will be stored. Now it's empty.
List<string> values = new List<string>();

// Whit this 'foreach' we iterate over 'gridData' selected cells.
foreach (DataGridCellInfo x in gridData.SelectedCells)
{
    // With this line we're storing the value of the cells as strings
    // in the previous list.
    values.Add(x.Item.ToString());
}

Then you can later make use of the stored values at your onClick() method.

You can see the following Microsoft MSDN site:
