Dear all,

I have a question about check box in datagrid. How can set the checkbox
is readonly in datagrid.?..

here is the code:

Dim tGrn As DataTable
Dim Colgrn As DataColumn
Dim Grndataset As New DataSet

Colgrn = New DataColumn
Colgrn.DataType = System.Type.GetType("System.Boolean")
Colgrn.ColumnName = "complete"
tGrn.Columns.Add(Colgrn)

Dim ts As New DataGridTableStyle
Dim cs1 As DataGridColumnStyle

cs1 = New DataGridBoolColumn
cs1.Width = 58
cs1.MappingName = "complete"
cs1.HeaderText = "Complete"
cs1.NullText = 0
cs1.ReadOnly = True <- Even set ReadOnly....but still
can click the checkbox ->
ts.GridColumnStyles.Add(cs1)

ts.MappingName = "tGrn"
grngrid.TableStyles.Add(ts)
grngrid.DataSource = tGrn
Grndataset.Tables.Add(tGrn)


also how can protect the datagrid..that not allow user add line again...

for example: I already have 10 records in datagrid...which have 3 column..
product code, product name and QTY.

I want to do that..not allow user to add line again but still can let user
to modify the QTY.

Thanks so much
Edmond

Hi,

Your tablestyle mapping name is probably wrong that is why the bool
column is not readonly

ts.MappingName = tGrn.Tablename

Prevent the add new line

tGrn.DefaultName.allownew=false
