"After the text" itemprop = "text">

I have the following hierarchy 

  Season 1 Farm 1 Field a tree with 1 Field-Scene 2 Crop 1 Crop 2 Farm 2 Field 1 field 2 crop 1 crop 2

to display a GridView data using against treeview node selected value.I SQLDataSource show data in gridview with the following code and query 

  as dim cmd OleDbCommand = new OleDbCommand () TreeView1.SelectedNode.Depth = 0 then select the SqlDataSource1.SelectCommand = ( "V_FARMS * where SSN_id = '' if & amp; TreeView1.SelectedNode. price & Amp; " '") elseif TreeView1.SelectedNode.Depth = 1 then choose SqlDataSource1.SelectCommand = ( "V_FARMS * where FRM_id =' '& amp; TreeView1.SelectedNode.Value & amp;"' ") elseif TreeView1.SelectedNode .Depth = 2 then SqlDataSource1.SelectCommand = ( "Choose V_FARMS where FLD_id = '" & amp; & Tree View 1. selected node. value and amp; "'") Elesef Tree VI 1. Selected node. Deepy & gt; 2 Then select the SqlDataSource1.SelectCommand = ( "V_FARMS * where CRP_id = '' & amp; TreeView1.SelectedNode.Value & amp;" ' ") End If

The problem now is that When I select Season 1 then it shows the data against Season 1 Ok. But when I choose Farm1 then this form is not 1 form 1 against Season 1 and also Field values ​​are same. How are the behaviors Together I can show the data of each node against my top parant node and root node etc. All data against all data

I suspect you are not using a diphout property. Each node Try to identify different values ​​of or maybe try to write the SQL statement in the tag of each node, when you try things.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
