Binding objectdatasource to an object

11-May-06 2:27

Ookay,
After about a full day searching on the internet I finally found a solution.

       <br />
 function resize_iframe()<br />
        {<br />
            var currentfr=document.getElementById("ctl00_PlaceHolderPSAHNNIntranet_iFrameRunningApplication");<br />
            var detect = navigator.userAgent;<br />
            place = detect.indexOf("MSIE");<br />
           <br />
            //if msie is not present in the string...<br />
            if (place == - 1) //Firefox<br />
            {<br />
                currentfr.width = currentfr.contentDocument.body.offsetWidth;                    <br />
                currentfr.width = eval(currentfr.width) + eval("16");<br />
<br />
                //change the height of the iframe<br />
                currentfr.height= currentfr.contentWindow.document.documentElement.scrollHeight +16; //window.outerHeight + 16; <br />
            }<br />
            else //Internet Explorer<br />
            {<br />
                currentfr.height = currentfr.Document.body.scrollHeight;<br />
                currentfr.width = currentfr.Document.body.scrollWidth + 15;<br />
            }<br />
        } <br />

Now I only need to find out how to get the Iframe to become smaller again, after a larger page had been inserted into it.

Edit: I found a solution for that aswell. Just put

<br />
currentfr.height = 15; //or any other height<br />

in the begining of the function. This will sort of reset the height.

hi all,

ok so I have an object in my business layer. With constructors,
properties and methods.

How do I bind an objectdatasource to my object? say the constructor?
pass in an ID to it that would fill the object and in turn the
ODS. And then bind the insert, delete and update tabs to appropriate
methods of the object.

is this possible?

thanks

M

You might want to read the tutorial in MSDN to see how to use the ObjectDataSource[^].

Unable to disable caching

Hi,

I think my problem is related to caching so here goes...

I have a web page in 'Application A' that retrieves data in the form of xml from a webservice exposed by 'Application B' - let's call it a list of tasks. The list of tasks is devided into two groups (outstanding and completed). Each task in the 'outstanding' list has a hyperlink. When the user clicks this hyperlink they are redirected to 'Application B' where they complete the task . 'Application B' sets the status of the completed task to 'completed'.
When the user returns to the list of tasks in 'Application A', the completed task needs to drop into the 'completed' list. This is however NOT happening, even if the page is refreshed (not even ctrl+F5 refreshes the lists). Upon testing I found that the data returned by 'Application B's webservice does refresh so the webservice is not the problem.

I have found if I reset IIS the page DOES refresh, so something is being cached somewhere.

I have tried the following so far...

In the code behind page I have included the following statements in the Page_Load() event handler
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);

This didn't make a difference.

I have also tried a page directive:
<%@ OutputCache NoStore="true" Location="None" %>

This didn't work either. Frown | :(

Any ideas?

Regards,
Morné

Make sure if you are displaying data in data grid EnableViewState should not be true (if data grid is the case this can be one problem).

before updating data (after refresh)
Cache.Remove("myTasks" )

then add new cache data

Hi Chinna,

Thank you for answering my question so quickly.

I'm displaying the data using a <asp:DataList> control with an <asp:XmlDataSource> as the datasource.

Setting the EnableViewState property of the DataList control to 'false' did not make a difference, but your suggestion made me also check the properties of the XmlDataSource control. It turns out that the XmlDataSource control has a property called EnableCaching which I then also set to 'false'... PROBLEM SOLVED!

Thank you for pointing me in the right direction. Smile | :)

Also make sure

You cannot have two applications listening on the same port. So you need to
either configure the other application to listen on another port, or close
the application

Security with WSE 3.0

Hi all

I installed WSE 3.0 and watched the Labs to learn how to apply security in my project. The problem is that in the Labs they use a Windows apllication and not a Web site. In the Labs u can see they got in the reference a file called Reference.cs .. what i don t have in my web site project (client side). I saw they change the "Policy" and use a method : proxy.SetPolicy(Policy); . So my question is : do i have to make a method for my Web Service and if yes .. how i can change the policy.
Thx a lot

System.IO Problem?

Hi I want to create Directories and Files in my project. But I don't want to use static methods of System.IO.Directory and System.IO.File because they are causing exceptions for some methods that this file is being used by some other process. How can I do this with classes from which we can make instance objects. I don't want to predefine the path or the file while creating new instance of the object.

Thanks,
Sandy

If you are trying to write to a file that is in use, then it wont make a difference how you try, you wont get to write to that file.

Using the static File and Directory methods is no different to using FileInfo and DirectoryInfo - which respectivly are the "instance" versions that you refer to.

In my application , I am uploading the images from the client. Then I am creating Directories to save those files. I have also functions to delete those files if the user want to do so. But after deleting the file and again uploading the new file to the same location give me the exception that this path or file is being used by another process. Now I am using FileInfo static methods to delete and save file but when I want to save file using FileControl by FileControlName.PostedFile.SaveAs(FilePath) method, it raises the above said exception.

Sandy

Are you sure you are properly closing your filestreams upon completion?

10-May-06 18:27

Please tell me the method to save a user uploaded file with the help of filestream . I had seen all the overload methods for declaring an object of FileStream object but all the methods demand the predefined FileName in the constructor. That is why I am using FileInfo class objects to perform those functions. But I couldn't find any function to close the FileInfo object.

Thanks,
Sandy

Hi, I have several listboxes in my application and the border is standard set to 'inset'. Is there any way to get rid of the border and just have a flat border?

Thanks in advance.

No, it doesn't work. I've tryed all different types of borderstyles and not one works.

That depends on what browser is used. Some browsers allow you to change the border style, others doesn't. Firefox does. Internet Explorer doesn't.
