I have a 2010 browser form (c#). some of the work in the form requires the fields values to be cleared. Is there an easy way to set a section of fields to blank? also I have to fields I can set to blank without IP bitting back

Date field I have tried

RateEffective.DeleteSelf();

RateEffective.SetValue("");

RateEffective.SetValue(null);

RateEffective.SetValue(string.Empty);

although the field is set to blank on most of these IP throws a validaton error on the field as if user enterend invalid data and the form will not save.

Also have a similar issue on a number field set to double, currency. I was forced to set it to 0, but I would rahter have it blank.

thanks and happy holidays

nevermind, not really sure what I missed, but set both values to string.Empty and it's working.

Thanks and enjoy

If the fields are set to allow blank values, then you will most likely get a validation error unless you re-add the xsi:nil attribute after setting them to blank.

Thanks Jimmy. Would you mind sharing an easy way to do that? I know it would soething like

@xsi:nill=true

but I am not sure how to apply it.

Sorry took so long to reply.

Jimmy hope you have a great holiday.

that worked perfectly, thanx

I am still hitting a wall. I have found that the client doesnt act the same as the borwser form. after some more research and what already has been provided I came up with this

if (RateExpiration.HasAttributes) 
{
if (RateExpiration.GetAttribute("xsi", NamespaceManager.LookupNamespace("my")) == null) 
{
RateExpiration.SetValue(string.Empty); 
RateExpiration.CreateAttribute("xsi", "nil", NamespaceManager.LookupNamespace("xsi"), "true"); 
}

}

else
{
RateExpiration.SetValue(string.Empty);
RateExpiration.CreateAttribute("xsi", "nil", NamespaceManager.LookupNamespace("xsi"), "true");

}

Please try this instead of RateExpiration.SetValue(string.Empty);

                if (RateExpiration.MoveToFirstChild())
                {
                    RateExpiration.DeleteSelf();
                }

This will actually delete the text content instead of replacing it with blank text, which is a subtle difference in browser forms.
