[cheryl]

Hello All,
if a column from datasource has a value of 1 the unbound checkbox column for that record should be enabled and if it''s 0 it should be disabled ...... What could the solution be ?

Thanx

Hi Cheryl,

You need to handle the QueryCellStyleInfo event to enable/disable the record in a groupingrid.Here is a code snippet.

Record r = e.TableCellIdentity.DisplayElement.ParentRecord;
if( r != null)
{
object obj = r.GetValue("Check"); //Check is the name of the unbound check box column
if( obj != null && obj.ToString() != string.Empty)
{
int checkValue = (int)obj;
if( checkValue == 1)
{
e.Style.Enabled = true;
}
else
e.Style.Enabled = false;

}
}

Please let me know if this helps.

hello haneef
I''ll rephrase the question

if a column from datasource has a value of 1 the unbound checkbox column for that record should be checked on form load and if it''''s 0 it should be unchecked ...... What could the solution be ?

Thanx

Hi Cheryl

Through the Record.GetValue() method the value of the record can be retrieved. Here is a small sample which gets the value from a bound column(from Datasource) in a grid (the column name is ''value'') and changes the value of the unboundcheckbox column (the column name is ''CheckBox'' ) in a grid. In the QueryCellStyleInfo event, the record''s value is retrieved as an object(o). With the object, the value of the unboundcheckbox column is changed through Record.SetValue() method. The code for the QueryCellStyleInfo event is as follows.

Record r = e.TableCellIdentity.DisplayElement.ParentRecord;
if( r != null)
{
object obj = r.GetValue("Value");
if( obj != null && obj.ToString() != string.Empty)
{
int checkValue = (int)obj;
if( checkValue == 1)
{
r.SetValue("CheckBox","True");//Set the value of unbound column;
}
else
r.SetValue("CheckBox","False");//Set the value of unbound column
}
}

Here is a sample.
