UltraGrid 7.2 not populating from data source in unit test
posted

Hi,

 I'm testing a component that search the grid and, in order to do this, am populating a DataTable with random data and assigning it as the DataSource on a UltraGrid. However, it appears the grid doesn't do anything with the data. Is this possible, or is the grid only functional on a form?

 My test code:

[TestFixture]

public class UltraGridSearcherFixture

{

private struct ColumnLabels

{

public static string Id = "Id";

public static string Qty = "Qty";

public static string Value = "Value";

}

[Test]

public void Test()

{

#region Create test data

const int ROW_COUNT = 1000;

DataTable data = new DataTable("DataRecord");data.Columns.AddRange(new DataColumn[

{

new DataColumn(ColumnLabels.Id, typeof(Guid)),

new DataColumn(ColumnLabels.Qty, typeof(int)),new DataColumn(ColumnLabels.Value, typeof(decimal))

}

);

for (int i = 0; i < ROW_COUNT; i++)

{

Random rnd = new Random(Environment.TickCount);

DataRow newRow = data.NewRow();

newRow[ColumnLabels.Id] = Guid.NewGuid();

newRow[ColumnLabels.Qty] = rnd.Next(-100, 100);

newRow[ColumnLabels.Value] = 1000 * rnd.NextDouble();

}

#endregion

UltraGrid grid = new UltraGrid();

grid.DataSource = data;

grid.DataBind();

Assert.AreEqual(ROW_COUNT, grid.Rows.Count);

}

}

    The grid is never going to paint here, so it will never actually do anything with the data.  You will need to put the grid on a form and show that form; I also tend to dock the grid to Fill as well to ensure that it's visible when doing unit tests.
