问题 I'm stumbling on this data converter stuff, especially with relation to multiple rows and dynamically show/hide an image. Lets take a master/detail data perspective. On a given view (presentation), I have header information and a data grid showing a bunch of line items. Before saving the line items, there could be one or more rows having missing/invalid data. I want to display a graphic image to the left of the line item giving the user some visual cue that ...hey, this row needs to be fixed.

问题 I want to convert a string representing the mantissa portion of a IEEE754 double.

问题 In a datatable, I have to validate the input as currency. When I enter the value after deleting the $ sign, the input component throws an error. <p:column> <f:facet name="header"> <p:outputLabel value="REC REVENUE" /> </f:facet> <p:inputText id="RERVN" styleClass="RERVN" value="#{segmentSetup.userSegmentTypesMap['RERVN'].segmentValues[rank].rangeMinValue}" disabled="#{!segmentSetup.userSegmentTypesMap['RERVN'].selected || (rank==fn:length(segmentSetup.ranks)) }" validator="#{segmentSetup

问题 I just made my first converter to convert from int to string. I have a combobox fill with integers(years) but if the value is 0 I want the combobox to show 'All'. This is my converter: public class IntToString : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value != null) { int intY = (int)value; if (intY == 0) { String strY = "All"; return strY; } else { return intY.ToString(); } } return String.Empty; } public object

问题 So, I have a multi-binding with a converter that takes in some values and finds the max of them. The problem is that one of the bindings utilises a converter that expects a double target type, while the binding has an object target type. I was wondering if there was any way to modify the target type of a binding in any way. Below is an approximation of my xaml: <TextBlock> <TextBlock.Width> <MultiBinding Converter="{StaticResource _maxValueConverter}"> <Binding Source="{StaticResource

问题 We are currently in the process of converting a project from version 3.5 to version 4.5 of .NET. We set a text box IsEnabled flagged using a multi binding with a multi binding converter. Each of the bindings has their own converter. All worked well in .NET 3.5 but in .NET 4.5 the target type that is passed to the child converter is of type object instead of bool. Is this a known issue? has MS refactored the multi binding to not pass the target type to child converters. I created a simplified
