asp.net - How do you avoid duplicate items when a databound control gets bound twice? -


How do you avoid duplicated byte items in this scenario:

A database control on one page ( In this case a dropdown list, though I do not think it matters). It has an accessoryband, which is set to "true" elsewhere in the code, a datasource has been set and called databand. So this control is clearly bound.

You have a bunch of other things to force on the page, so you call the page. Databand

Your data-bound control has duplicate items in it. This (1) was clearly bound, then (2) the page Since AppendDataBoundItems was correct, the second tie adds the first time, and you repeat the items.

Some limitations:

  1. Draft on clear call control is done through some centralized code, and will be painful to change.

  2. I need to force the rest of the page to be completely (through the page. Databind ()) because many different database elements allow different calls To be written without individually.

I need a method like ... page.DatabandExceptionActiveBibleBoundDown ()

Close the offending bandwidth when you are in control. Databand () Then you page DataBind () will not rejoin the item. 

  DropDownList.DataSource = Data; DropDownList.DataBind (); DropDownList.AppendDataBoundItems = Incorrect;

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...
