Multi-column combo box in a gdbg

[Roberto Guerzoni]

Hello, I tried to use as a multi-column combo box in a GridDataBoundGrid but I could not find a good example. 

I would like to show in a grid column a multi-column combo box with data from a DataTable that is not connected to the grid, 

how can I do? 

Thank you very much

Hi Roberto Guerzoni,

 

Thank you for your interest in Syncfusion Products.

 

Query: Multi-column combo box in a gdbg

We Would like to convey that reported query can be resolved by using GridPreviewstyleinfo event. In which by setting, the celltype as GridListControl, you can easily obtain MultiColumnCombobox in GridDataBound control. For your better understanding, CodeSnippet is given below,   void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)         {              if (e.ColIndex == 2 && e.RowIndex == 3)             {                 e.Style.CellType = GridCellTypeName.GridListControl;                 e.Style.DataSource = USStates();                 e.Style.CellValue = "US";                 e.Style.DisplayMember = "LongName";                 e.Style.ValueMember = "ShortName";             }         }   For your better convenience, we’ve added a sample below, http://www.syncfusion.com/downloads/support/directtrac/126914/gbg-991142667.zip

 

Please let us know, if you’ve any further concerns.

Hi Maniratheenam

I used the feature in a slightly different way, If it can be useful to someone here is the code that is used

public StationsForm()

{

....

//

// Format the columns in the DataTable that we will use in GridListControl associated with the column RackId

//

m_ioRacksViewDataTable.Columns["RackId"].ColumnName = CommonResource.RackId;

m_ioRacksViewDataTable.Columns["Description"].ColumnName = CommonResource.Description;

m_ioRacksViewDataTable.Columns["IPAddress"].ColumnName = CommonResource.IPAddress;

m_ioRacksViewDataTable.Columns.Remove( "IPPort" );

m_ioRacksViewDataTable.Columns.Remove( "Node" );

m_ioRacksViewDataTable.Columns.Remove( "SlaveKind" );

m_ioRacksViewDataTable.Columns.Remove( "ModbusSlaveId" );

....

}

private void StationsForm_Load( object sender, EventArgs e )

{

if( !m_initialized )

{

m_initialized = true;

assemblyStationsGrid.BeginUpdate();

assemblyStationsGrid.Binder.InternalColumns["StationId"].Position = 1;

assemblyStationsGrid.Binder.InternalColumns["StationId"].Width = 100;

assemblyStationsGrid.Binder.InternalColumns["Description"].Position = 2;

assemblyStationsGrid.Binder.InternalColumns["Description"].Width = 500;

assemblyStationsGrid.Binder.InternalColumns["IPAddress"].Position = 3;

assemblyStationsGrid.Binder.InternalColumns["IPAddress"].Width = 150;

assemblyStationsGrid.Binder.InternalColumns["RackId"].Position = 4;

assemblyStationsGrid.Binder.InternalColumns["RackId"].Width = 150;

assemblyStationsGrid.Binder.InternalColumns["CS1PositionSwitch"].Position = 5;

assemblyStationsGrid.Binder.InternalColumns["CS1PositionSwitch"].Width = 150;

assemblyStationsGrid.Binder.InternalColumns["CS2PositionSwitch"].Position = 6;

assemblyStationsGrid.Binder.InternalColumns["CS2PositionSwitch"].Width = 150;

var style = assemblyStationsGrid.Binder.InternalColumns["RackId"].StyleInfo;

style.CellType = GridCellTypeName.GridListControl; // TIP - MultiColumnComboBox

style.DropDownStyle = GridDropDownStyle.Exclusive; TIP - Comment out the line if you want to allow editing of the column

style.DataSource = m_ioRacksViewDataTable;

style.DisplayMember = CommonResource.RackId;

style.ValueMember = CommonResource.RackId;

//style.ShowButtons = GridShowButtons.ShowCurrentRow; // TIP-Uncomment theline if you want the grid to display the selection buttons only in selected row

style.HorizontalAlignment = GridHorizontalAlignment.Left;

assemblyStationsGrid.EndUpdate();

}

}
