Is this Grid bound to a datasource already & do you want to add one more row to it ?

there is no datasource bound to it there is no database.

i simply want to construct the rows from the variables and display it in the datagrid

Solution 1

First you need to add in DataTable like

C#

DataRow dr = dt.NewRow();

dr["ID"] =int.Parse(reader[0].ToString());
dr["title"] = reader[2].ToString();
dr["jobint"] =int.Parse(reader[3].ToString());
dr["lastrun"] = DateTime.Now;
dr["nextrun"] = lastrun.AddSeconds(jobint);
dt.Rows.Add(dr);


//BindGridViwe

Gridview1.DataSource = dt;
Gridview1.DataBind();

Hi there,
While using a tutorial found here
I Programmer
I worked through the example and adapted it for your needs.

public partial class MainWindow : Window
    {
        public struct MyData
        {
            public int id { set; get; }
            public string title { set; get; }
            public int jobint { set; get; }
            public DateTime lastrun { set; get; }
            public DateTime nextrun { set; get; }
        }
        public MainWindow()
        {
            InitializeComponent();
            DataGridTextColumn col1 = new DataGridTextColumn();
            DataGridTextColumn col2 = new DataGridTextColumn();
            DataGridTextColumn col3 = new DataGridTextColumn();
            DataGridTextColumn col4 = new DataGridTextColumn();
            DataGridTextColumn col5 = new DataGridTextColumn();
            myDataGrid.Columns.Add(col1);
            myDataGrid.Columns.Add(col2);
            myDataGrid.Columns.Add(col3);
            myDataGrid.Columns.Add(col4);
            myDataGrid.Columns.Add(col5);
            col1.Binding = new Binding("id");
            col2.Binding = new Binding("title");
            col3.Binding = new Binding("jobint");
            col4.Binding = new Binding("lastrun");
            col5.Binding = new Binding("nextrun");
            col1.Header = "ID";
            col2.Header = "title";
            col3.Header = "jobint";
            col4.Header = "lastrun";
            col5.Header = "nextrun";

            myDataGrid.Items.Add(new MyData { id = 1, title = "Test", jobint = 2, lastrun = new DateTime(), nextrun = new DateTime() });
            myDataGrid.Items.Add(new MyData { id = 12, title = "Test2", jobint = 24, lastrun = new DateTime(), nextrun = new DateTime() });
        }
    }

The code behind shown above seems to be fairly straight forward. The XAML is as follows:

XML

<Window x:Class="DataGridTester.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <DataGrid x:Name="myDataGrid"/>
    </Grid>
</Window>

Hope this helps
