[CLOSED] Universal PartialViewResult Problem

[tiramisu]

Hi vladimir

To simplify my project, I made my own version of a partialviewresult. The problem is, like in a thread before, to activate ID's that are aleady rendered.


The Interesting Part is:

myControllerContext.HttpContext.Response.Write("if(!Ext.get('" + myXControl.ClientID + "')){" + myXControl.ToScript(this.RenderMode, this.ContainerId ?? "={Ext.getBody()}", this.Index, true) + "} else { Ext.get('" + myXControl.ClientID + "').activate;}");

How can I check if a ID is there - and if yes - activate/show/bring to front - regardless if it's a tab or something else...

Thanks

I managed to rework the oneliner mentoined at the top:

 
myControllerContext.HttpContext.Response.Write("if(!Ext.get('" + myXControl.ClientID + "')){" + myXControl.ToScript(this.RenderMode, this.ContainerId ?? "={Ext.getBody()}", this.Index, true) + "} else { " + myXControl.ClientID + ".show();Ext.get('" + myXControl.ClientID+ "').frame();}");

I think that should be part of the toolkit. The code above is really ugly :cool::cool:

Hi,

I'm pretty use you won't avoid switch() { } of if() {} instructions...

To determine a type of control I would suggest you to use .getXType() method:
http://dev.sencha.com/deploy/dev/doc...ember=getXType

Instead of Ext.get(id) you could use Ext.getCmp(id) to retrieve a component.

Also I would suggest you to define a function on client side and :

myControllerContext.HttpContext.Response.Write("myFunction('"+ myXControl.ClientID + "')");

Hi daniil

I adressed this post directly to vladimir, because he was also creating that functionality in this : http://forums.ext.net/showthread.php...sal+controller

Basicly its JavaScriptResult coming back from the partialviewresult. But I need generic functions to handle windows/tabs show/recration/bring to front etc.

Ok, I also interested what Vladimir will tell us:)

Dear vladimir

Have you seen I have a special question for you. :cool:

Best regards, Flavio

Hi,

Sorry, I missed your topic.

Well, I suggest to check control existence on the clisnt side before request (if control exists then activate it else make request and render it)
But I like your idea about overrding default functionality during rendering (now the widget always destroyed before rendring). I guess we have to add some js callback which will be called if control with the same id exists, in that call back you can do anything (destroy, activate and etc)
I think we will create feature request

The Feature Request ticket has been created.

Hi

Basicly I think it should be possible do that on the client.

- Multiple windows/tabpanels allowed: No Id is set
- Single windows/tabpanels: Id must be set accordnigly to the URI (Example: AdministrationClientIndex for AREA-ControllerAction)

The code below shows my testsample. The problem is the "ctl01_" string... were come that from?

 
<script type="text/javascript">
function load(myUrl, myContainerId) 
{
var myId = "ctl01_" + myUrl.replace(/\//g, '');

if (!Ext.getCmp(myId)) 
{
Ext.Ajax.request({url: myUrl,method: "GET",params: { myContainerId: myContainerId },success: function (response) { eval(response.responseText); }})
}
else 
{
Ext.getCmp(myId).show();
Ext.get(myId).frame();
}
}
</script>

Best regards, Flavio

Hi,

The problem is the "ctl01_" string... were come that from?

If a widget is placed inside control (including UserControl and Master pages) which implement INamingContainer then its ClientID will be complex (will be composed from parents ids)

From the MSDN documentation:

"Any control that implements this interface creates a new namespace in which
all child control ID attributes are guaranteed to be unique within an entire
application. The marker provided by this interface allows unique naming of
the dynamically generated server control instances within the Web server
controls that support data binding. These controls include the Repeater,
DataGrid, DataList, ListBox, CheckBoxList, HtmlSelect, and RadioButtonList
controls."

Basically, this interface causes the ASP.NET runtime to do it's job relative to control naming. It is a "marker" interface, meaning that some piece of code, e.g., the ASP.NET runtime, will use its presence to take some action.

You can override ClientID generation behaviour, set IDMode="Explicit" for required widget and ID will equal ClientID always
