TableControlCheckBoxClick and preventing specific rows from being ''checkable''

[James Blibo]

I have a checkbox in the first column (header and records).

How do I prevent specific rows from being checkable.

For example, when the user attempts to check row 3, I want to prevent that row from being check if the 'Status' of that row record is set to 'inactive', for example. Likewise, I want to skip over this row when the user check the header to checks all the records in the grid.

I know that I can do it from the TableControlCheckBoxClick event via e.Inner.Cancel = true, but I am not sure if style.TableCellIdentity.RowIndex directly maps to the row index of the underlying datasource, given the fact that the grid is sortable, ect..

Hi James,

Thank you for being patience.

The idea to skip and disable the checkbox whose row is inactive is by handling the QueryCellStyleInfo event and set the corresponding checkbox to be disabled.

For example, in the following code snippet the column 'Col2' decides the row being inactive or active
>>>>>>>>>>>>>>>Code Snippet<<<<<<<<<<<<<<<<<<<
private void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
if(e.TableCellIdentity.TableCellType == GridTableCellType.RecordFieldCell || e.TableCellIdentity.TableCellType == GridTableCellType.AlternateRecordFieldCell)
{
if(e.TableCellIdentity.Column.Name.Equals("Col0"))
{
Element el = e.TableCellIdentity.DisplayElement;
if(el != null && el.Kind == DisplayElementKind.Record)
{
Record r = el.GetRecord();
string key;
if (r != null && r.GetValue("Col2") != null)
{
key = r.GetValue("Col2").ToString();
if(key.Equals("inactive"))
{
e.Style.CellValue = false;
e.Style.Enabled = false;
e.Handled = true;
}
}
}
}
}
}
