ASPxGridView - 如何只使用DataSource属性添加示例值？

Question

Hello I have a ASPxGridView. In it(for the uninformed) is only a DataSource property for telling it what data to load. My problem is that I'm simply trying to mock up an example and don't need to tie it to an actual database. How would I do this? I basically just want a few rows and some columns but since it only takes a datasource I'm not sure how to do it. Would ObjectDataSource be what I'm looking for?

Answer 1

Just set the datasource to a list of anything like this:

public class Item
{
  public string Name { get; set; }
  public int Count { get; set; }
}

protected void Page_Load(object sender, EventArgs e)
{
  GridView1.DataSource = new Item[] { new Item { Name = "2", Count = 2 }, new Item { Name = "3", Count = 3 }, };
  GridView1.DataBind();
}


<dxwgv:ASPxGridView ID="grid" ClientInstanceName="grid" runat="server" Width="100%" AutoGenerateColumns="False" >
     <Columns>
         <dxwgv:GridViewDataTextColumn Caption="Name" FieldName="Name" ReadOnly="True">
         </dxwgv:GridViewDataTextColumn>
         <dxwgv:GridViewDataTextColumn Caption="Count" FieldName="Count" ReadOnly="True" >
         </dxwgv:GridViewDataTextColumn>
     </Columns>
     </dxwgv:ASPxGridView>

Two other ways using DataTable:

    private DataTable getSampleDataSource1()
    {
        DataTable dtblResult = new DataTable();
        dtblResult.Columns.Add("Name");
        dtblResult.Columns.Add("Count");

        dtblResult.Rows.Add("Name1", "1");
        dtblResult.Rows.Add("Name2", "3");
        dtblResult.Rows.Add("Name3", "7");
        dtblResult.Rows.Add("Name4", "9");

        return dtblResult;
    }

    private DataTable getSampleDataSource2()
    {
        DataTable dtblResult = new DataTable();
        dtblResult.Columns.Add("Name");
        dtblResult.Columns.Add("Count");

        DataRow drow;
        drow = dtblResult.NewRow();
        dtblResult.Rows.Add(drow);
        drow.ItemArray = new object[] { "Name1", "1" };

        drow = dtblResult.NewRow();
        dtblResult.Rows.Add(drow);
        drow.ItemArray = new object[] { "Name2", "3" };

        drow = dtblResult.NewRow();
        dtblResult.Rows.Add(drow);
        drow.ItemArray = new object[] { "Name3", "7" };

        drow = dtblResult.NewRow();
        dtblResult.Rows.Add(drow);
        drow.ItemArray = new object[] { "Name4", "9" };

        return dtblResult;
    }

    private void setDataSource(ASPxGridView theGridView)
    {
        theGridView.KeyFieldName = "Name";
        theGridView.DataSource = getSampleDataSource1();
        theGridView.DataBind();
    }
