hi
write the code for dynamically creating checkbox in a function
and call this function from both in form load each time and in button click

The checkBoxes build (amount, values, etc) depends on the selected date in the calendar. I can't build the checkBoxes on page_load because i don't know what is the current date in the calendar (the page_load events occurs before the SelectionChanged of the calendar, so the calendar doesn't hold the pressed date in page_load)

"This is an invalid webresource request."

I have an ASP.NET custom control in a class library, which (apart from server-side logic) has client-side functionality. As far is I know this is best achieved by adding the javascript file to the project as an embedded resource and registering it via code, like this:

string scriptLocation = Page.ClientScript.GetWebResourceUrl(this.GetType(), "Namespace.Control.js");
Page.ClientScript.RegisterClientScriptInclude("Namespace.Control.js", scriptLocation);

Now the funny thing is, it works as expected on one site, however if used on a page in a second site that uses the same class library, I get the following Exception:
"This is an invalid webresource request.". Google only came up with solutions for cases, where it doesn't work at all. Right now I have absolutely no idea what could cause this different behavior for the 2 sites. Any comment on the subject would be appreciated.

AJAX: using UpdatePanel with DataList

Talal Sultan15-Oct-07 3:53

Hi all,

I have a user control with one datalist that displays thumbnails of pictures stored in the database. In the same user control, I have an Image control where I would like to display a zoomed version of the picture when the user clicks on one of the thumbnails of the datalist.

In the datalist, I have ImageButton controls to show the thumbnails. When the user clicks a thumbnail, I get the item index and retrieve the corresponding image from the dataset in the session. The image is stored as a byte array. I save the image in another session variable that will be used by an ASPX page to display it. I point the ImageUrl of my Image control to that ASPX page.

The ItemCommand event handler is as follows:

protected void dlVisuals_ItemCommand(object source, DataListCommandEventArgs e)
    {
        int index = e.Item.ItemIndex;
        DataRow dr = sessionParams.SiteDS.Tables["TempVisuals"].Rows[index];
        Session["VisualZoom"] = SiteServices.GetThumbnail((byte[])dr[2], 300, 300);
        imgZoomFeature.ImageUrl = "ZoomVisualImage.aspx";
        imgZoomFeature.Visible = true;
    }

The aspx code to show the image is as follows:

if (Session["VisualZoom"] != null)
       {
           Bitmap bmp = new Bitmap(new MemoryStream((byte[])Session["VisualZoom"]));

           bmp.Save(Response.OutputStream, ImageFormat.Jpeg);
       }

I have put the datalist AND the Image control in an UpdatePanel and set the trigger to the ItemCommand event of the datalist.

The code works fine for the FIRST click only, i.e. when the user clicks on a thumbnail after the user control has been loaded. Subsequent clicks do not have any effect on the Image control. I have stepped into the code and I verified that the event handler is being called correctly at each thumbnail click. It seems that the ASPX page displaying the image is not working properly. I put a breakpoint in it but the program doesn't stop at it.

Any ideas?

Thanks,
Talal

Hi,
I am using Visual studio 2005 for building my website. the website is working fine.
But the issue is: I am getting a compilation warning.

Warning: Unable to update auto-refresh reference 'chartfx.internet.dll'. Can not find assembly

'c:\Documents and Settings\kncsnmr\Local Settings\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies\5cvgir0d01\ChartFX.Internet.dll'.

I manual browsed through my disk with above path. I was only able to go till 'ProjectAssemblies'. Because there was nothing in the ProjectAssembly folder to reach the end of the above path.

Please let me know how to clear out this compiler warning.

I would greatly appreciate any kind of help on this.

Thanks
Mohamed.

Might be beacuse of this dll 'chartfx.internet.dll'
are you using this dll in your application if yes then check that dll remove that dll and add once again or try to refresh that dll ?

Thanks and Regards

Ajax Extensions: using update panel w/validation.

I'm using an UpdatePanel along with a RegularExpressionValidator to inform the user if he/she has input the date in an incorrect format. This works fine once, but if the user types in the date wrong a second time, it doesnt show the validation error message. Any help would be appreciated. Smile | :)

Textbox:
autopostback = true;
causesvalidation = true;

UpdatePanel:
updatemode = Always;

use the following javascript function.. pass the target url, width and height of the window to be opened.

function OpenWindow(url, width, height)
{
if( url == null || url == "" )
{ return false; }
else
{
var handle = window.open(url, "scrollbars=yes,screenX=25,screenY=25,directories=0,height=" + height + ",width=" + width + ",location=no,menubar=no,resizable=yes,status=no,toolbar=no"); +
Children.push(handle);
handle.focus();
return handle;
}
}

If the Javascript function that is used to popup the window return's True then it will refresh. To avoid this page post back set the return value to False

Hi,
If i am not wrong, that you want to covert your that VB Script code to VB.Net. and that's why i want to know the object of that function , that what it should do? for vb.net you have to use the System.management dll and nets System.Management Namespace.

I just want to know from you that what u are trying to do using that function. Or you want to convert any VB Scipt WMI code to VB.Net WMI.

Happy Programming
