WPF TextBox.Text with MultiBinding -


मेरे पास डिफॉल्ट टेम्पलेट में एक टेक्स्ट बॉक्स के साथ कस्टम कंट्रोल है I कस्टम नियंत्रण में इन 2 निर्भरता गुण हैं (अन्य के बीच में):

चयनित वैल्यू, नलटेक्स्ट (पाठ्य पाठ में दिखाई देने के लिए टेक्स्ट, जब कुछ भी नहीं चुना जाता है और मूल्य प्रदान किया जाता है)

मैं चाहता हूं जैसे पाठ बॉक्स को सेट करें। NullText के साथ पाठ मान जब SelectedValue नल है और NullText शून्य नहीं है। 

 <कोड> & lt; TextBox.Text & gt; & Lt; मल्टिबाइंड कनवर्टर = "{स्टेटिक रिसोर्स मायकोनवर}" & gt; & Lt; बाध्यकारी रिलेटिव सोर्स = "टेम्प्लेटेड पेरेंट" पथ = "चयनित वैल्यू" / & gt; & Lt; बाध्यकारी रिलेटिव सोर्स = "टेम्प्लेटेड पेरेंट" पथ = "नलटेक्स्ट" / & gt; & Lt; / MultiBinding & gt; & LT; /TextBox.Text>

मुझे एक IMultiValueConverter मिला है: 

  सार्वजनिक वर्ग MyConverter: IMultiValueConverter {}

इस XAML परिभाषा के साथ मैं 'प्रकार के पास एक सार्वजनिक टाइपकॉन्टर क्लास नहीं है' अपवाद

आप इसे कैसे हल करेंगे, कृपया?

मुझे अपने द्वारा समाधान मिला: समस्या रिलेटिवसार्स के साथ थी यह ऐसा कैसे दिखना चाहिए: 

  & lt; टेक्स्ट बॉक्स। पाठ & gt; & Lt; मल्टिबाइंड कनवर्टर = "{स्टेटिक रिसोर्स मायकोनवर}" & gt; & Lt; बाध्यकारी रिलेटिव सोर्स = "{रिलेटिव सर्स टेम्पलेटेड पेन्ट}" पथ = "चयनित वैल्यू" / & gt; & Lt; बाध्यकारी रिलेटिव सोर्स = "{रिलेटिव सर्स टेम्पलेटेड पेन्ट}" पथ = "नलटेक्स्ट" / & gt; & Lt; / MultiBinding & gt; & LT; /TextBox.Text>

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
