winforms - calling one child form from another child form in c# -


itemprop = "text">

I have 3 forms: FormA, FormB, and FormC, in which formA is the mdiParent form and Form B and C are Child Forms. I will write the following code in FormA Load Event. 

  Private zeros frmMain_Load (Object Sender, EventArgs e) {formB.MdiParent = this; // Form B formb form c. MDPER = this is; // formC is an example of Formal Formby. Show (); }

What do I do when I click on a button on the formab, then the pharmacy must be shown. Now to do this I would need to make another example of the FCCA when the button click in the formality or should I be able to use the built in forma

if there is a need to make a different example Can anyone explain the reason for doing so?

Edit- The answer given by Oedde makes me feel right but can I create return type of property in form [] to add more than 1 reference so that if I withdraw from Formaci from Forma If I want to go, can I use the same method?

I want to pass some data from the pharmacy, so how can I do this?

Your formb to formsCONT is required.

You can add an asset to your FromB to do this: 

  the public form formCF {get; Set;}

then in its main form: 

  formB.FormCRef = formC;

And do this in your FormB class in your event handler: 

  FormCRef.Show ();

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...
