c# - How to load javascript function from an dynamicall added control? -

-

The master page got a script manager.

Then I got a control with ScriptManagerProxy and UpdatePanel.

There I need to add a control dynamically (there is also a ScriptManagerProxy) inside the UpdatePanel and with that control I need to run some javascript code.

DynamicControl.ascx: & lt; Script type = "text / javascript" & gt; Function doSomething () {warning (1); } & Lt; / Script & gt;

DynamicControl.ascx.cs: 

  Public Zero Page_load (Object Sender, EventArgs e) {... ScriptManager.RegisterStartupScript (this.page, this Gettype (), "script id", "& lt; script type = 'text / javascript' & gt; doSomething (); & lt; / script & gt;" false);   
  My problem is that "doSomething ()" function is never called and I do not know why: s  edit: it is called , But when I add control, I am not directly.  
 If I code like this, then there will be an alert window:  
  "script" = type 'text / javascript' & gt; alert (1) ; & Lt; / scripts & gt;   
  OK I think I need to add some more information:   
 The control has been added to a dynamical which can be used in the jQuery dialog Is inside And I came to know that after the shutdown, JavaLoad is executed for the first time and then opens the dialogue. Any type of event is triggered so that the code is executed, I think. Is it possible to stress this incident? Can the script be directly executed when the control is added?  
  placeHolder.Controls.Add (dynamicReportControl);   
 Does this C # code immediately execute the Javascript tag?   
 
 
 Please try something like this  
  ScriptManager.RegisterStartupScript ( This.UpdatePanel1, this.UpdatePanel1.GetType (), "scriptID", "script type = 'text / javascript' & gt; DoSomething (); & lt; / script & gt;" false);   
 Where UpdatePanel1 is your UpdatePanel

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.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
