Supressing binding errors

[Emil Alexiev]

I have a report which binds to a Dataset.  Dataset loads an xml file which sometimes doesn't contain all elements (if user didnt specify any data for those elements).  If an element such as 'Name' is missing I will receive "An error has occurred while processing TextBox 'Name': The expression contains object 'Name' that is not defined in the current context".  Instead I just want the report to leave the textbox blank if the binding fails.  Is it possible to somehow supress binding errors if the biniding element doesn't exist?
Thanks, Emil.

Hello Emil Alexiev,

In order to avoid the expression's exception our suggestion is to utilize the following user function:

public static string GetValue(Processing.ReportItem reportItem, string field)
{
    try
    {
        return reportItem.DataObject[field].ToString();
    }
    catch
    {
         return "";
    }
}

Once you add the GetValue user function, build the project and use the following expression for the TextBox.Value:
= GetValue(ReportItem,"Name")

All the best,
