I am trying to create a new validation on WMSBillOfLadingOrder.
I am trying to create a new validation on WMSBillOfLadingOrder.
I created field names grossWeight and tareWeight.
Validate is grossWeight greater Than tareWeight.
this is EventHandler

Dear pavilionit, please stop selecting all categories for all your questions. For example, how is this question related to "continuous updates" or "Management Reporter"? It seems to me that "Development / Customization / SDK" is the only fitting category.
I'm going to fix all your threads, but please make sure you do it correctly next time. Thank you.
thanks for helping me
Hi pavillionit,
I suggest you to search the web for existing documentation, blogs and discussions. And if you need general help with event handler syntax, please post a new question. Also could you mark the helpful answer(s) as verified if your original problem is now solved? Thanks!
firstly thanks for your help
if you can just for me
show me how to set or build event handler to improve my skills and thanks again
Hi pavillionit,
yes I understand this requirement. But the validateWrite() of your Chain of Command class is already doing it. So you don't need an event handler to do the same thing again! Just take the code that I shared earlier and try it. If you have some problems with it, investigate them, and let us know if you need help.
[DataEventHandler(tableStr(WMSBillOfLadingOrder), DataEventType::ValidatedWrite)]
when i insert value must be validate for the number if gross greater than tare the value for weight is changed and if gross less than tare i need show message to customer
I'm sorry, I don't understand your question. What do you need the event handler for? You're now using Chain of Command for the validateWrite method, so you don't need event handler for the same method.
Regarding your code, it has issues as pointed out earlier, and I recommend to fix them before we move forward.
this is the all code i use it
[Extensionof(tableStr(WMSBillOfLadingOrder))]
final class Training_WMSBillOfLadingOrder_Table_Extension
{
public void modifiedField(FieldId _fieldId)
{
ValidateEventArgs validateArgs = e as ValidateEventArgs;
WMSBillOfLadingOrder WMSBillOfLadingOrder = sender as WMSBillOfLadingOrder;
boolean result = validateArgs.parmValidateResult();
next modifiedField(_fieldId);
switch (_fieldId)
{
case fieldNum(WMSBillOfLadingOrder, grossWeight):
case fieldNum(WMSBillOfLadingOrder, tareWeight):
this.calculateWeight();
break;
}
}
void calculateWeight()
{
this.validateWrite();
this.weight = this.grossWeight - this.tareWeight;
}
boolean validateWrite()
{
boolean ret= next validateWrite();
if(this.grossWeight<this.tareWeight)
{
//this.TWeight = this.orig().TWeight;
throw error("Gross Weight should be reereerr or equal to Tare Weight");
}
return ret;
}
}
and this is EvenHandle method from a table i got it
[DataEventHandler(tableStr(WMSBillOfLadingOrder), DataEventType::ValidatedWrite)]
public static void WMSBillOfLadingOrder_onValidatedWrite(Common sender, DataEventArgs e)
{
ValidateEventArgs validateArgs = e as ValidateEventArgs;
WMSBillOfLadingOrder WMSBillOfLadingOrder = sender as WMSBillOfLadingOrder;
boolean result = validateArgs.parmValidateResult();
}
now
how to write the method on WMSBillOfLadingOrder_onValidatedWrite to get the true result
You should call validateWrite() only before insert/update, not in some calculation method.
Also, you should not update values in validateWrite(). The user must be able to see the values that caused the issue!
So, perhaps your code should look something like this:

public void modifiedField(FieldId _fieldId)
{
next modifiedField(_fieldId);
switch (_fieldId)
{
case fieldNum(WMSBillOfLadingOrder, grossWeight):
case fieldNum(WMSBillOfLadingOrder, tareWeight):
this.calculateWeight();
break;
}
}
void calculateWeight()
{
this.weight = this.grossWeight - this.tareWeight;
}
boolean validateWrite()
{
boolean ret= next validateWrite();
if(ret && this.grossWeight < this.tareWeight)
{
ret = checkFailed("Gross Weight should be reereerr or equal to Tare Weight");
}
return ret;
If something is missing, please try to describe the requirement with as much detail as you can. Like you would do if the other person knew nothing about the requirement. Because we don't know :)
One more thing - why do you even need to store "Weight" separately? If it's always determined by Gross weight - Tare weight, why go through all the trouble of maintaining this sum in a third column? Seems like extra effort that's not really needed.
this is code validate in entering values and calculate the weight.
I need to make code on DataEventHandle does the same thing
public void modifiedField(FieldId _fieldId)
{
next modifiedField(_fieldId);
switch (_fieldId)
{
case fieldNum(WMSBillOfLadingOrder, grossWeight):
case fieldNum(WMSBillOfLadingOrder, tareWeight):
this.calculateWeight();
break;
}
}
void calculateWeight()
{
this.validateWrite();
this.weight = this.grossWeight - this.tareWeight;
}
boolean validateWrite()
{
boolean ret= next validateWrite();
if(this.grossWeight<this.tareWeight)
{
//this.TWeight = this.orig().TWeight;
throw error("Gross Weight should be reereerr or equal to Tare Weight");
}
return ret;
