I have datagrid with 5 items. Out of which 1 items are checkboxes. The bool
column(checkbox column ) in added in datagrid.  The rest of Data is binded
dynamically to the datagrid

Based on some values from the database I have to check or uncheck the
checkbox in the datatgrid.

i am not able to change the value of checkbox at runtime. Does any one know
how to do this in windows form?

try this For the datagrid you must be having a Datatable. Using the
DataTableObject try this
__DataTable.Rows[RowIndex][ColumnIndex] = true;  // ColumnIndex refers to
the checkbox column,RowIndex refers to the corresponding row.

fine.. Try this one
ts.Rows[0]["MyBoolColumn"] = true;
I assume ts refers to DataTable object, "MyBoolColumn" refers to Boolean
Column,"0" refers to 1st row in the grid.

Also add this code as part of the DataGridTableStyle for Boolcolumn to have
2 states true/false rather than 3 states.// Dim txtID6 As New
DataGridBoolColumn()
>                 txtID6.MappingName = "MyBoolColumn"
>                 txtID6.HeaderText = "CHECKBOX"
>                 txtID6.Width = 80
VJ: Dim dgColumn  as DataGridBoolColumn dgColumn =
(DataGridBoolColumn)myDGColumnSelect;
This property will set to either true or false state...

VJ: dgColumn.AllowNull = false;

ts.GridColumnStyles.Add(txtID6)
