You might run into problems again when you reference to masterpage from subdirectories

To avoid that, reference the js file in your masterpage as follows:
(Inside Body Tags)

<script src="<%= Me.ResolveURL("filename.js") %>" type="text/javascript"></script>

Persistent client side changes

derm227-Apr-08 6:24

ASP.Net seems to keep an eye out for some client side changes such as checkboxes, while completely ignoring other stuff. Losing Style.visibity information during postbacks really hurts for example.

Is there a way to make asp remember such changes, or to check them during postback, and set them myself?

If viewstate is turned on for a control, then changes are remembered. Any non server controls, are not remembered at all.

Viewstate only seems to remember specific changes. Look at the following code, for example.

if (!Page.IsPostBack)<br />
{<br />
    string str = "<script type='text/javascript'>";<br />
    str += "document.getElementById('CheckBox3').style.visibility='hidden';";<br />
    str += "document.getElementById('CheckBox2').checked=true;";     <br />
    str += "</script>";       <br />
    Response.Write(str);<br />
}

It will add javascript to check checkbox2, and hide checkbox3 on the clicent side if it's not a postback. Now do a postback. Checkbox2 will stay checked, but checkbox3 will turn visible after a postback. Viewstate is enabled for both checkboxes.

Well, I am surprised it remembers the check, and you're lucky it works at all. This is silly code. Set the Visible and Checked properties on the .NET class instances, and both will be remembered.

derm229-Apr-08 2:18

It remembers the check, because that's how any html form remembers the check or textfield data during postback.

Of course this can be done on the server side and be remembered, and probably most examples are silly. This was not the question Smile | :)

Then think of this, as it's more like a real life example: The user can show or hide a div with a button (client side code). This div should not magically appear after a postback if it's hidden or vice versa.

Postback is slow. You don't want to postback and wait just to hide something, to change the backcolor or to sort a table when it can be done instantly on the client side.

I agree. But, when I do client side stuff, I don't expect viewstate to find it all, I would tend to use a server hidden control to store values telling me what I had done on the client side in script.

I get what you're saying, viewstate would be cooler if it worked better. I guess I'm just saying I'm glad when stuff works at all :P

Thanks for the input, the hidden field should do the job.
And we shall see what they make for us in the next version of ASP.net Smile | :)

Hey

Well i have like 300 computers on my network and most of them are running on windows 98 .

my friend build a web application that asks the user for a catalog
number and in javasciprt it display the "catalognum.jpg"
the problem is that after the user load something like 20 pictures
the page is not showing more pictures,it's look like that there is no memory ....

here is most of the code

function myfunction(filpath)
{

if (filpath !== "")
{
imgtasrit.src = "DocLib/"+filpath+".jpg";
}
else
{
imgtasrit.src = "image003.gif";
}
}

/script>
.....
input type = button value="??? ?????" onclick="myfunction(form1.tb1dk.value)" align="right" id="Button1" >

i just wondering if there is way to clean the memory on client side ?

This is using ASP.NET ? I'd still ask in the web dev forum, as it's a generic client side question.

Problem dynamically painting a control in a SharePoint WebPart

27-Apr-08 11:36

You don't need AJAX at all, although you could use it. Just set a timer using one of the many javascript timer code examples that exist on the web. Set the users starting time on the server, and always use that to reset the timer on postback ( it's so easy to change client side script, you should never rely on it being correct ).

I am writing a WebPart for SharePoint and am having trouble re-painting a control (not ASP control) when I want to reflect some scripting action.

My class inherits from "Microsoft.SharePoint.WebPartPages.WebPart".

I found the ASP listbox control lacking because I wanted to include a checkbox, graphics as well as text for each item.

An array of checkboxes contained within a div (for scrolling) contained in a feldset (for a border to contain the entire set) made for a good display of the data with the ability to access each item individuality.

The array is rendering the way I want it with a checkbox, icon and text for each item and the scrolling is working properly.

I am able to check and un-check each individual item in the array of checkboxes but the CheckAll() and ClearAll() functions are not checking or clearing all the items in the array.

Can anyone tell me what I need to do to make the CheckAll() and ClearAll() functions work?

In "protected override void RenderContents(HtmlTextWriter writer)"

<br />
                writer.Write("<fieldset style='width: 760px;'>");<br />
                writer.Write("<legend><strong>" + lblDocInfo.Text + "</strong></legend>");<br />
<br />
                writer.Write("<div style='overflow: auto; height: 145px;'>");<br />
<br />
                foreach (string folder_key in current_folders)<br />
                {<br />
                    writer.Write("<input type=checkbox name='" + folder_key + "' id='" + folder_key + "'><img src='http://sharepointservername/projectname/websitename/icons/folder.ico' align='middle'> " + folder_key.Substring(folder_key.LastIndexOf("/") + 1) + "</input><br />");<br />
                } // foreach(string folder in current_folders)<br />
<br />
                foreach (string doc_key in current_docs)<br />
                {<br />
                    writer.Write("<input type=checkbox name='" + doc_key + "' id='" + doc_key + "'><img src='http://sharepointservername/projectname/websitename/icons/doc.ico' align='middle'> " + doc_key.Substring(doc_key.LastIndexOf("/") + 1) + "</input><br />");<br />
                } // foreach(string doc in current_docs)<br />
<br />
                writer.Write("</div>"); // <div style='overflow: auto; height: 145px;'><br />
<br />
                writer.Write("</fieldset>");<br />
<br />
                writer.Write("<br /><br />");<br />
                writer.Write("<input id='btnCheckAll' type='button' value='Check All Documents' onclick='CheckAll();' style='width: 380px;' />");<br />
                writer.Write("<input id='btnClearAll'type='button' value='Clear All Checked Documents' onclick='ClearAll();' style='width: 380px;' />");<br />
                writer.Write("<br />");<br />
                btnProcess.RenderControl(writer);<br />
                writer.Write("<br /><br />");<br />

and further down in the code

<br />
                writer.Write("<script type='text/javascript'>");<br />
<br />
                writer.Write("function CheckAll(){");<br />
                foreach (string doc_key in current_docs)<br />
                {<br />
                    writer.Write("document.getElementById(doc_key).checked = true;");<br />
                } // foreach(string doc in current_docs)<br />
                writer.Write("document.getElementById('btnClearAll').disabled = false;");<br />
                writer.Write("}"); // function CheckAll()<br />
<br />
                writer.Write("function ClearAll(){");<br />
                foreach (string doc_key in current_docs)<br />
                {<br />
                    writer.Write("document.getElementById(doc_key).checked = false;");<br />
                } // foreach(string doc in current_docs)<br />
                writer.Write("document.getElementById('btnClearAll').disabled = true;");<br />
                writer.Write("}"); // function ClearAll()<br />
<br />
                writer.Write("</script>");<br />

What does it mean ?
How does it occur ?
and what should I do ?

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Tnx

It means that you have an application level section in a web.config file that is not in the root folder of your web.

Either you have put an illegal section in a web.config file in a folder in your application, or what you think is the root folder of your application is just a folder in another application.

Despite everything, the person most likely to be fooling you next is yourself.

What do you mean by 'dynamic' ? Creating resources for each language is the best way I can think of to create resources so you can change the language of your site, if you wanted it to happen via some translation algorithm or something, that could only end in tears.

Re: Using javascript functions ?

26-Apr-08 9:46

hi,,
on my project asp.net with c#
I added a javascript item for eg,, name : JS.js
and made the next function :

function PopUpQtyWindow(id)<br />
{<br />
 window.open("productqty.aspx?id=" + id, "Cart", "status = 1, height = 150, width = 200, resizable = 0"); <br />
}

then on any page i tried to call this function as next :

<br />
int prodID = 1 ;<br />
HyperTest.NavigateUrl = "javascript:PopUpQtyWindow(" + prodID + ");";

when running project and press the hyperTest .. status message " Error on page " .

thanks for all .
