Java JTable restructure / reload / refresh -


I have a tree and a table, when I click on the tree node, the time the table will change on the same, but It is not. I search online and read Java tutorials and I do not find any solutions. From some posts I think I need to use fireTableStruetureChanged () , but it does not work in my code Can anyone help me with this? The following code is thanks a ton! 

  Change the table structure of the public category increases the geometric tool ... {..... // // column name is a public variable, because I'll have to change the column later column name = new string [] {"Col1", "col2"}; * / Data = new string [] [] {{"Mary", "champion"}, {"alison", "attack"},}; Table = new JTable (new MyTableModel ()); Table.setAutoCreateColumnsFromModel (wrong); Feedback = new JScrollPane (table); // is the response panel below

... 

 } // Following is the square problem, I need to reload the table i when class , But the table is not changed in all public Zero Exhibits. Fabke (String Template String) {// Create table for panel column below name = new string [] {"col3", "col4", "col5"}; String [] [] Data = New string [] [] {{"Mary", "Campione", "We"}, {"Alison", "Humble", "Canada"}}}; // table = new JTable (data, column-name); // fireTableStructureChanged (); // This table is the problem I table model class MyTableModel AbstractTableModel {String [columnnames = new string] Extends {"col1", "col2"}  
  public int getColumnCount () { Return columnNames.length; } Public int getRowCount () {return data. Long; } Public string getColumnName (int col) {returning column names [col]; } Public object getValueAt (int row, int col) {return data [row] [cola]; }}  
 
 ...}

In your method, Code> Display Feedback You are expecting to change the Joint object and there is a change in display to display the selected code in JTree . Instead of taking a place in the view object, you should focus your efforts on updating the model , in this case, the AbstractTableModel subclass is ready Already happened. There are some methods you can do, but there is proof of concept for a tremendous force, you can do something like:

  • Adds a 2-dimensional array in data
  • , create a new example of MyTableModel , which is the new data related to selected selected tree nodes is.
  • Call setModel on your global table variable

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 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...
