Asked On March 15, 2011 08:18 AM UTC

1)For grid control/data bound grid, How can I make the grid never have edit mode for the cell of certain columns while the whole row always being selected? E.g. there're 6 columns in a grid, and column 4, 5, 6 are read only and not editable, thus the cells of these column should not have the edit mode.

2)For these 2 types of grid, How can I change the select back color and select fore color when the whole row is selected?
Once I try to remove Alphablend from AllowSelection list(Because it can not provide me the conventional selection effect: blue background and white text ), it turns out the selection back color become black?

Hi Feng,

Thanks for using Syncfusion products.

Regarding Non-Editable Cell:

In GridDataControl,
you can make particular column as non-editable by setting ReadOnly property as True in the respective VisibleColumn of the DataGrid like shown below:

Code Snippet[XAML]

In GridControl, you can make particular column or cell or row as non-editable by setting ReadOnly property as True in the QueryCellInfo event of the datagrid like shown below:

Code Snippet[C#]

this.grid.QueryCellInfo += new GridQueryCellInfoEventHandler(grid_QueryCellInfo);

void grid_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
if (e.Cell.ColumnIndex > 3)
{
e.Style.ReadOnly = true;
}

e.Style.CellValue = string.Format("Row{0}/Col{1}",e.Style.RowIndex,e.Cell.ColumnIndex);
}

Regarding Background and Foreground Color for Selected Rows:

In GridDataControl, you can achieve your requirement like shown below:

Code Snippet[C#]

this.dataGrid.HighlightSelectionBackground = Brushes.Blue;
this.dataGrid.HighlightSelectionForeground = Brushes.White;

In GridControl, you can achieve your requirement like shown below:

Code Snippet[C#]

this.grid.Model.Options.DrawSelectionOptions = GridDrawSelectionOptions.ReplaceBackground | GridDrawSelectionOptions.ReplaceTextColor;
this.grid.Model.Options.HighlightSelectionBackground = Brushes.Blue;
this.grid.Model.Options.HighlightSelectionForeground = Brushes.White;

For your reference we have also attached the sample herewith.
