Description Property (UltraGridRow)

Returns or sets the text that will be displayed as a description.
Syntax
'Declaration
 
Public Overridable Property Description As String
public virtual string Description {get; set;}
Remarks

The Description property determines the text that will be displayed in the AutoPreview area for a row. This property will be read-only if its band's AutoPreviewField property is set to a valid field or column name.

The following sample code enables the row previews in the UltraGrid.InitializeLayout event and sets descriptions of rows in UltraGrid.InitializeRow event.

C#:

            private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
            {
                // Enable the row previews.
                //
                this.ultraGrid1.DisplayLayout.Bands[0].AutoPreviewEnabled = true;
            }
            
            private void ultraGrid1_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)
            {
                Infragistics.Win.UltraWinGrid.UltraGridBand band;
                band = this.ultraGrid1.DisplayLayout.Bands[0];
            
                // Check for the row being from the same band.
                //
                if ( e.Row.Band == band )
                {
                        // Create a custom description that we want shown in the row's
                        // row preview area.
                        //
                        System.Text.StringBuilder description = new System.Text.StringBuilder( );
            
                        description.Append( e.Row.GetCellText( band.Columns["ContactName"] ) );
                        description.Append( "\n" );
                        description.Append( e.Row.GetCellText( band.Columns["City"] ) );
                        description.Append( ", " );
                        description.Append( e.Row.GetCellText( band.Columns["Country"] ) );
            
                        // Set the row's Description to our custom description text.
                        //
                        e.Row.Description = description.ToString( );
                }
            }
Example
The following sample code sets row descriptions for row preview area in the InitializeRow event. It assumes there are ContactName, City and Country columns in band 0.
