asp.net - Accessing listview itemtemplate from codebehind -

-

I'm hoping to dynamically change the number of columns in my ItemView in my ListView: < Pre> & lt; Asp: ListView runat = "server" id = "report listview" datasource id = "Reportist VJSDS" & gt; & Lt; LayoutTemplate & gt; & Lt; Table & gt; & Lt; TR & gt; & Lt; Asp: placeholder runat = "server" id = "itemplay" /> & Lt; / TR & gt; & Lt; / Table & gt; & Lt; / LayoutTemplate & gt; & Lt; ItemTemplate & gt; & Lt ;! - Select COMMAND, depending on the selection statement, the number of columns in the rear code needs to be dynamic - & gt; & Lt; / ItemTemplate & gt; & Lt; / ASP: ListView & gt;

Then I got the code behind it: 

  protected sub page_Load (ByVal as the object, byVal E. System.EventArgs ) Handles me On the basis of load 'sent request.Form variables, select the X number of columns':' SqlStatement = Select "For each Request.Form values" "From Employees" Example: "Select FName 'Run SQL command' works by all the Lname, Email, Phone Staff, now the question is how will I change the item 'Times' template so that it has the correct number column. Pseudo code) for each line ("& lt; tr & Gt; ") for each Request.Form as I reportLIstView.ItemTemplate.Add (" & lt; TD & gt; "sqlresult: something like this (i) & amp;" & lt; / td & gt; ") Next ReportListView.ItemTemplate.Add (" & lt; / tr & gt; ") Next End Sub   
 There may be another way to go about this, but This is the only idea so far. Asp.net newbie, any advice, is very welcome! Thanks!   
 
 < P> I think you have to do this in a slightly different way. Try to do something like that. I:  
  & lt; Table & gt; & Lt; Asp: ListView id = "ListView1" runat = "server" & gt; & Lt; ItemTemplate & gt; & Lt; TR & gt; & Lt; Asp: Place Holder ID = "Place Holder 1" Runat = "Server" /> & Lt; / TR & gt; & Lt; / ItemTemplate & gt; & Lt; / ASP: ListView & gt; & Lt; / Table & gt;   
 The syntax may not be correct, but try to reverse something like this in your code:  
 PLC in each item Request.Form plc.Controls.Add string (New verb (String.Format ("as & lt) as  placeholder = DirectCast (listItem.FindControl (" Placeholder 1 "), placeholder) Then nothing isnot for, TD> {0} & lt; / td> ", item))) Next End if Next

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.
