Enable/Disable a Field in a Grid Row Based on Another Column's Value in Dynamics 365

Hello everyone.

I have a question regarding enabling and disabling a specific control within a grid based on the selection of a value from another column.

To clarify, I have a scenario that requires securing one of the columns if its value differs from "PenaltyType::Warning". I used the "OnModified" event of the control itself and wrote the following code:

[FormControlEventHandler(formControlStr(JmgParameters, ViolationPenalties_PenaltyCode), FormControlEventType::Modified)]
public static void ViolationPenalties_PenaltyCode_OnModified(FormControl sender, FormControlEventArgs e)
{
    PenaltyType penaltyType = PenaltyTypes::find(sender.valueStr()).PenaltyType;
    FormRun formRun = sender.formRun();
    FormControl cntrol = formRun.design().controlName("ViolationPenalties_Penalty");
    if (penaltyType == PenaltyType::Warning) 
    {
        if (cntrol)
        {
            cntrol.enabled(true);
        }
    }
    else
    {
        if (cntrol)
        {
            cntrol.enabled(false);
        }
    }
}

This code works, but the result is different from what I want because it disables the entire column containing the "ViolationPenalties_Penalty" control. However, I need to secure only the field in the specific row I am currently on, without affecting other rows in the column.

I thought about using data source events, but I’m not sure about the correct way to implement this scenario.

Thank you in advance.

Hi Ali,

Try the active datasource method instead

Hello Layan Jwei,
I would like to thank you for helping me find the solution. I tried the OnActivated event, and it seemed to be the most appropriate solution, but it became clear to me that I was using the "enabled" function, and it appears that the structure of this function is designed to disable the entire column even if this code is in the OnActivated event. I modified my code and used another function on the cell itself instead of trying to disable the input control. I used the "allowEdit" function instead of "enabled," and the code became as follows:
[FormDataSourceEventHandler(formDataSourceStr(JmgParameters, ViolationPenalties), FormDataSourceEventType::Activated)] public static void ViolationPenalties_OnActivated(FormDataSource sender, FormDataSourceEventArgs e) { ViolationPenalties currentRecord = sender.cursor() as ViolationPenalties; if (currentRecord) { if (PenaltyTypes::findByRecid(currentRecord.PenaltyTypesReferenceGroup).PenaltyType == PenaltyType::Warning) { sender.object(fieldNum(ViolationPenalties, Penalty)).allowEdit(true); } else { sender.object(fieldNum(ViolationPenalties, Penalty)).allowEdit(false); } } }

Thank you for your help.
