Binding winComboBox

[User (Old forums)]

#18436 |

Ok, here we go. I am trying to bind a dataset to a form with several comboboxes. I am using the following code to bind to the winComboBox

wcbL_PROPCLASS.DataBindings.Add(New Binding(“Text”, Globals.dsDD, “tblACT_LAND.CLASS”, True))

The data in the dataset is a value of “R” and the combobox should display “RESIDENTIAL”

I get no value at all. I have bound the data to a plain textbox and it does have the value.

What am I doing wrong ?

I suggest that you directly use the DataSource and the DataMember properties instead.

Here is a simple example:

<code>
private void Form1_Load( object sender, EventArgs e )
{
for( int j = 0; j < 4; j++ )
{
Column col = new Column( “Column” + j.ToString() );
gridControl1.Columns.Add( col );
}

for( int i = 0; i < 20; i++ )
{
Xceed.Grid.DataRow row = gridControl1.DataRows.AddNew();
foreach( Cell cell in row.Cells )
{
cell.Value = “Item ” + i.ToString();
}
row.EndEdit();
}

DataSet ds = new DataSet();
ds.Tables.Add( getDataTable() );

WinComboBox wcb = new WinComboBox(EnhancedBorderStyle.None);
wcb.DataSource = ds;
wcb.DataMember = “MyTable”;

gridControl1.Columns[ 0 ].CellEditorManager = new ComboBoxEditor( wcb );
}

private DataTable getDataTable()
{
//Create a DataTable
DataTable dt = new DataTable();
dt.TableName = “MyTable”;
DataColumn dcId = new DataColumn();
dcId.ColumnName = “Index”;
dcId.DataType = System.Type.GetType( “System.Int64” );
dt.Columns.Add( dcId );

DataColumn dcName = new DataColumn();
dcName.ColumnName = “Value”;
dcName.DataType = System.Type.GetType( “System.String” );
dt.Columns.Add( dcName );

for( int i = 0; i < 50; i++ )
{
System.Data.DataRow row = dt.NewRow();
row[ “Index” ] = i;
row[ “Value” ] = i.ToString() + “%”;
dt.Rows.Add( row );
}

return dt;
}
</code>
