asp.net - please help me in creating a sort expressions for datatable in vb.net -


I have found a statistic that has several columns with three main ones:

  1. hotelid
  2. Hotel names

Some hotels have only dshotelid, some are only picky and some have both datholide and hive.

I should sort out so that the hotels should be topped for both the Doshotid and Hotel hotel and then those hotels will get only Dashotid and for the hotels that are near the hotel only. ...

> Please help me make such an expression.

I made it: 

  dtmaintable.DefaultView.Sort = "dshotelid, hotelid"

but it does not make me the desired output Is giving up.

at the top of the sorted column (unless sort order is in descending order) Maybe looking at the rows below with hotel hotels and dashotids, instead of p?

How is this data table populated? If it is coming from a database query, it is a simple matter to create an additional column (or column) that has the sorting of your needs - this is a mix of other columns or some other unique identifier.

Edit: February 4, 2010 - In response to your 'Filter and Certified' solution:

Your solution works, but this filter and Not because of the sortable label - this is because you used a different type of command.

By default, you use "dsohtelid, hotelid"

For the second time, you have "dshotelid desc , hotelid desc ".

It will not use your non-top in top and tap, but I will dispute that it will pass as a good solution. Your ID is now backwards sort - just like the way I think you I want to avoid, so suggestions from my new sort column would be respected.

However, if the ID does not make sense, then your solution is fine and you can stay with the addition of 'desc' with your original code, such as: 

  Dtmaintable.DefaultView.Sort = "dshotelid desc, hotelid desc"

Of course, if I said anything that any kind of use has been done for you, then tick is appreciated Will go. This will help me reach 50 representative points and will eventually be able to write a comment. :)

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...
