How to Disable Fields of a Form DataSource

In Dynamics, you have the ability to control user input by disabling fields within a form’s data source. This feature can be quite useful to ensure that certain fields are not modified accidentally.

Disabling Individual Fields

To disable a specific field within a form’s data source, you can utilize the following syntax:

SalesLine_ds.object(fieldNum(SalesLine, SalesPrice)).allowEdit(false);

In this example, the SalesPrice field of the SalesLine data source is set to be non-editable,
preventing any changes from being made to it.

Disabling All Fields of a DataSource

If you find the need to disable all the fields within a data source, you can achieve this with the following statement:

SalesLine_ds.allowEdit(false);

Remember to replace SalesLine with the actual name of the data source you are working with.
This approach can be particularly useful when you want to restrict any modifications to the entire data source.

Disabling All Fields Except Specific Ones

In some scenarios, you may want to disable all fields within a data source except for a specific set.
Here’s an approach you can use to achieve this:

public static void SetAllTableFields()
{
    DictTable dictTable = new DictTable(SalesLine.TableId);
    int i;
    int fieldNumber;

    for (i = 1; i <= dictTable.fieldCnt(); i++)
    {
        fieldNumber = dictTable.fieldCnt2Id(i);
        if (SalesLine_Ds.object(fieldNumber) && fieldNumber != fieldNum(SalesLine, LinePercent)
            && fieldNumber != fieldNum(SalesLine, SalesPrice))
        {
            SalesLine_Ds.object(fieldNumber).allowEdit(false);
        }
    }
}

In this example, the SetAllTableFields method iterates through all the fields of the SalesLine data source, except for the LinePercent and SalesPrice fields. For each field within the iteration, the allowEdit property is set to false, effectively rendering them non-editable.
