dynamic

问题 Greetings, hopefully there is a simple solution for this complex problem. Please correct any misconceptions I have along the way. A while ago I wrote a GrivView with dynamic column capability. The columns are added in the OnInit page event so that they are added BEFORE the viewstate is applied. They are reapplied on every posting in this section of the page so that when the viewstate is applied changes that the user has made and not committed to the database are maintained. It also is

问题 I have 16 uniquely named dropdowns on a web page. When the page loads, the user has the option on any of the dropdowns to select a value of 0 to 16. 0 is the default on all of them. Now, unless the value is 0, when a user selects a value for one of the dropdowns. I want that value to not be an available option for any of the other dropdowns. This continues until you get to the last dropdown where the only options are the last available number and zero. The issue is, it works fine in Chrome

问题 I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority. The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it. The "making the GridView row display it" part is the one that's giving me a hard time. What's the best

问题 Please I have a class in c# whose main function is to return the types and objects as dictionary Over a service . Is it possible to cast the Object sents over the WCF service in the front end. I.e using reflection to get the type of an object from the types.ToString() and using the type to cast the objects. NB the Class that returns the dictionary and my frontend are in different projects so different Namespaces: Type repType = typeof(List <>).MakeGenericType(Type.GetType(EntityandTypes

问题 I have been reading up a lot on Angular 2+ i18n and have been looking for the best way to try and build dynamic components. Problem: i18n cannot translate a variables text into an xlf file for dynamic i18n makes it hard to make dynamic components with text using i18n attribute Possible Solution: Even though we cannot use dynamic strings in variables for i18n to pick up when generating the language resource file we should still be able to create components and pass text to them. For the

问题 I have a web page index.php, I want to add and remove JS files to this page dynamically So far I did, <script type="text/javascript" src="" id="dynamic_files"></script> I had planned to change the src of this script tag by function loadJsfiles( filename ){ var filePath = 'include/js/'+filename; $("script#dynamic_files").attr('src',filePath); }; and the included js file has script tags in it: document.write('<script type="text/javascript" src="include/js/profile1.js"></script>'); document

问题 I'm trying to come up with a function to translate various human date/time-format strings to Python compatible ones (from '*yyyy-MMM-dd*' to '*%Y-%b-%d*' ). So far I built the translate dictionary below (a list of tuples [('yyyy','%Y'),('MMM','%b'),...] ) so I can convert placeholder fields in input format-strings into strptime '%x' fields e.g.: 'yyyy-MMM-dd' --> '{5}-{3}-{12}' But what do I do next? I've tried multiple ways: >>> re.sub('({\d+})',translateList['\1'][1],'{5}-{3}-{12}')

问题 I'm building a Mac OS X application that is to embed Python. My application is technically a bundle (i.e. its main executable is MH_BUNDLE); it's a plug-in for another application. I'd like it to embed Python statically, but want to be able to load extensions dynamically. I did the following: I included a whole library ( -force_load path/to/libpython2.7.a ), also reexported all Python symbols ( -exported_symbol_list path/to/list ), and added the -u _PyMac_Error , which I got using this

问题 I have a database that users can run a variety of calculations on. The calculations run on 4 different columns each calculation does not necessarily use every column i.e. calculation1 might turn into sql like SELECT SUM(Column1) FROM TABLE WHERE Column1 is not null and calculation2 would be SELECT SUM(Column2) WHERE Column2 is null I am trying to generate this via linq and I can get the correct data back by calculating everything every time such as table.Where(x => x.Column1 != null) .Where(x

问题 I need a way to cast an object to a type that is not know at compiler time. something like this: object obj; public (type of obj) Obj { get { return obj } set { obj = (type of obj)value; } } The only thing that is know is that obj is a value type. I doubt that something like this would be possible. Just checking to see if someone has a clever way of doing it. 回答1: This is not possible in C# 3.0, but if you could define a common interface that all of your objects implement, you could cast to
