Converting a datagrid cell to a string in a WPF C# application

I'm currently trying to get the contents of a selected row in a DataGrid to appear in individual text boxes outside of the DataGrid when a button is pressed. As it stands, I can get the values into their respective textboxes, however instead of just giving me the cell value as a string like I want it to, the textboxes display the value type like this: System.Windows.Controls.DataGridCell: Leary.

I've tried converting the cell value to a string a couple different ways, but my latest attempt to do this looks like this:

    var rowSelection = EditGrid.GetSelectedRow(myGrid);
    var columnSelection = EditGrid.GetCell(myGrid, rowSelection, 3);
    string cellToEdit = Convert.ToString(columnSelection);

    customerNameTxt.Text = cellToEdit;

I can supply the EditGrid class that I created if someone would like to see it, however, I do not think that's where the issue is since I am getting the correct cell into each textbox; I'm hoping it's simply a formatting issue.

Thanks in advance to anyone who can help

How are you UI logic implemented? Things like this in WPF are really easy when you do it the MVVM way. If your DataGrid works bound to a collection of entities, you can just bind your TextBox.Text to a property of the DataGrid.SelectedItem.

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
    xmlns:local="clr-namespace:WpfApplication1"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="MainWindow"
    Width="525"
    Height="350"
    mc:Ignorable="d">
<Window.DataContext>
    <local:ViewModel/>
</Window.DataContext>
<Grid x:Name="LayoutRoot">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <DataGrid x:Name="MyDataGrid" ItemsSource="{Binding Items}"/>
    <TextBlock Grid.Column="1" Text="{Binding SelectedItem.MyProperty, ElementName=MyDataGrid}"/>
</Grid>
</Window>

Try to cast it to your UIElement:

string cellToEdit = ((TextBlock)columnSelection.Content).Text;
