Answer 1

//Xaml Code
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Path=Date, Converter={StaticResource    dateconverter}, Mode=OneWay}" Header="Date" Width="100"/>
<DataGridTextColumn Binding="{Binding Path=Prescription}" Header="Prescription" Width="900"/>
</DataGrid.Columns>

//C# Code
 DataRowView row = (DataRowView)grid1.SelectedItem;
 MessageBox.Show(row["Prescription"].toString() + " " + row["Date"].toString());

As WPF provides binding in DataGrids, this should be rather transparent. However, the following method only works, if you have used SQLDataAdapter and provided a binding path to your DataGridColoumns. For eg. Let's say the above datagrid is named grid1, which has auto generate columns set to false, and is using binding to bind column names to Headers. In this case, we use the 'row' variable of type 'DataRowView' and store the selected row in it. Now, use your Binding Paths, and reference individual columns of the selected row. Hope this helps! Cheers!

PS: Works if SelectionUnit = 'Row'

Answer 2

Worked For me

object item = dgwLoadItems.SelectedItem;
string ID = (dgwLoadItems.SelectedCells[0].Column.GetCellContent(item) as TextBlock).Text;
MessageBox.Show(ID);

Answer 3

you can also use this function.

 public static void GetGridSelectedView(out string tuid, ref DataGrid dataGrid,string Column)
    {
        try
        {
            // grid selected row values
            var item = dataGrid.SelectedItem as DataRowView;
            if (null == item) tuid = null;
            if (item.DataView.Count > 0)
            {
                tuid =  item.DataView[dataGrid.SelectedIndex][Column].ToString().Trim();
            }
            else { tuid = null; }
        }
        catch (Exception exc) { System.Windows.MessageBox.Show(exc.Message); tuid = null; }
    }

Answer 4

These are 2 methods that can be used to take a value from the selected row

    /// <summary>
    /// Take a value from a the selected row of a DataGrid
    /// ATTENTION : The column's index is absolute : if the DataGrid is reorganized by the user,
    /// the index must change
    /// </summary>
    /// <param name="dGrid">The DataGrid where we take the value</param>
    /// <param name="columnIndex">The value's line index</param>
    /// <returns>The value contained in the selected line or an empty string if nothing is selected</returns>
    public static string getDataGridValueAt(DataGrid dGrid, int columnIndex)
    {
        if (dGrid.SelectedItem == null)
            return "";
        string str = dGrid.SelectedItem.ToString(); // Take the selected line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Delete useless characters
        if (columnIndex < 0 || columnIndex >= str.Split(',').Length) // case where the index can't be used 
            return "";
        str = str.Split(',')[columnIndex].Trim();
        str = str.Split('=')[1].Trim();
        return str;
    }

    /// <summary>
    /// Take a value from a the selected row of a DataGrid
    /// </summary>
    /// <param name="dGrid">The DataGrid where we take the value.</param>
    /// <param name="columnName">The column's name of the searched value. Be careful, the parameter must be the same as the shown on the dataGrid</param>
    /// <returns>The value contained in the selected line or an empty string if nothing is selected or if the column doesn't exist</returns>
    public static string getDataGridValueAt(DataGrid dGrid, string columnName)
    {
        if (dGrid.SelectedItem == null)
            return "";
        for (int i = 0; i < columnName.Length; i++)
            if (columnName.ElementAt(i) == '_')
            {
                columnName = columnName.Insert(i, "_");
                i++;
            }
        string str = dGrid.SelectedItem.ToString(); // Get the selected Line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Remove useless characters
        for (int i = 0; i < str.Split(',').Length; i++)
            if (str.Split(',')[i].Trim().Split('=')[0].Trim() == columnName) // Check if the searched column exists in the dataGrid.
                return str.Split(',')[i].Trim().Split('=')[1].Trim();
        return str;
    }

Answer 5

When I faced this problem, I approached it like this: I created a DataRowView, grabbed the column index, and then used that in the row's ItemArray

DataRowView dataRow = (DataRowView)dataGrid1.SelectedItem;
int index = dataGrid1.CurrentCell.Column.DisplayIndex;
string cellValue = dataRow.Row.ItemArray[index].ToString();

Answer 6

Please refer to the DataGrid Class page on MSDN. From that page:

Selection

By default, the entire row is selected when a user clicks a cell in a DataGrid, and a user can select multiple rows. You can set the SelectionMode property to specify whether a user can select cells, full rows, or both. Set the SelectionUnit property to specify whether multiple rows or cells can be selected, or only single rows or cells.

You can get information about the cells that are selected from the SelectedCells property. You can get information about cells for which selection has changed in the SelectedCellsChangedEventArgs of the SelectedCellsChanged event. Call the SelectAllCells or UnselectAllCells methods to programmatically select or unselect all cells. For more information, see Default Keyboard and Mouse Behavior in the DataGrid Control.

I have added links to the relevant properties for you, but I'm out of time now, so I hope you can follow the links to get your solution.
