Hello,

I have a grid which have two fields.

1. Lookup

2. StringEdit.

What I want is, when I change lookup and the selected value is “1” then I want the another stringEdit should be disabled…else enabled…

It seems so simple, but I can’t fins it out.

Can you help me…??

</div>

Table\_ds.object(fieldnum(Table,StringField)).allowEdit(Table.lookupfied == “1”);

put the above code in the active method of the form datasource.

hope both are the fields from data source.

Try by adding a new method to the form methods

void enableFields()

{

Table\_ds.object(fieldnum(Table,StringField)).allowEdit(Table.lookupfied == “1”);

}

and call this method in active method

public int active()

{

int ret;

ret = super();

element.enableFields(); // call the method here

return ret;

}

The code that is being suggested to be placed in active() should work to set the property appropriately as you move between records in the grid, however, you will also need that code in the modified() override on the “Lookup” DataSourceField to account for the case where the user changes the value in the lookup.

As david said call the same method (enableFields()) in the modified method of the lookup field…

Hi Abhishek,

Override ‘modified method’ of the lookup field. Use the following code

public boolean modified()  
{  
boolean ret;

if (TestTable\_LookupField.text() == “1”)

{  
TestTable\_StringEdit.enabled(false);  
}  
else  
{  
TestTable\_StringEdit.enabled(true);  
}  
ret = super();  
return ret;  
}
