Are you getting any error ?

Probably tage <> not allowed to send as message. However you can do one thing replace these tag with any special character on client side and then again parse it on server side.

Actually, there is a standard format for this already.

By html encoding it first. For example, a space becomes %20.

Thanks for the reply,

is there any built-in funtion to format the html messges or do we need to need manually parse all tags and convert it to a normal string?

Thanks

not sure in js. I would expect you'd find one on the web, I doubt one is built in.

Ok i got this function from web and it worked

var encodedHtml = escape(NewsBody_rich.document.body.innerHTML);
     encodedHtml = encodedHtml.replace(/\//g,"%2F");
     encodedHtml = encodedHtml.replace(/\?/g,"%3F");
     encodedHtml = encodedHtml.replace(/=/g,"%3D");
     encodedHtml = encodedHtml.replace(/&/g,"%26");
     encodedHtml = encodedHtml.replace(/@/g,"%40");

I was thinking about another way to pass the data to server using hidden textbox

I thought of putting the formatted html message to a asp hidden textbox and take it in the code-behind using the following script

document.getElementById("TextBox1").value=NewsBody_rich.document.body.innerHTML;

but this not working, when i put alert after this script code it shows the TextBox1.Value as assigned html message, but when i debug in the code-behind the TextBox1.Text value is empty. i dont know why?! i did lot of debugging still couldnt able to find, i even replace asp server textbox with html server texbox, still not working!!
Do you have any idea why is it so!?

Thanks

Recently I've been looking at the release of the extensibility framework and the new addin namespace in .Net 3.5. This has me wanting to play around with my own extensions for web apps.

I know DNN has modules. I'm trying to wrap my head around how to implement my own extensions in my applications. Can I use an existing framework? How would I go about this.

I'm sure I'm not asking the right questions. I've done some searching and cannot find any answers. Please help.

I'm using a 3rd-party component for a shopping cart (dotnetCART), and I am having a problem formatting a string. I know that since this is a 3rd-party control, you all may not be able to help, but I thought I's ask anyways...

The dotnetCART component has a web control called "Display Catalog" which displays products from the database. Although fields such as "Price" and "Weight" are included in the web control, my "WholePrice" field is not, and so I have to pull it in using the "GetCustom" property (or is it called a method?).

Right now the code in question looks like this:

<br />
< dotnetCART:DisplayCatalog ><br />
<br />
    ...some code...<br />
<br />
    < ItemDetailsTemplate><br />
        < asp:Label <br />
            ID="lblWholesalePrice" <br />
            runat="server"<br />
            Text='<%#Container.GetCustom("WholePrice") %>'><br />
        < /asp:Label><br />
    < /ItemDetailsTemplate><br />
< /dotnetCART:DisplayCatalog><br />

(FYI, a non-custom field would have been written into the label as "<%#Container.Price%>")

The above label works OK, but it displays the data without formatting, and so my "WholePrice" appears as "12.55" or "6.554", not "$6.55". I've read the asp.net information on formatting strings, and I have tried to apply a similar formatting syntax to the "Container.GetCustom" without success. I have tried:

<br />
Text='<%#Container.GetCustom(FormatCurrency("WholePrice")) %>'>

...returns an error from the component: "Conversion from string "WholePrice" to type 'Double' is not valid."

Text='<%#Container.GetCustom("WholePrice","{0:c}") %>'
...returns "BC30057: Too many arguments to 'Public Function GetCustom(strField As String) As String'."

Text='<%# DataBinder.Eval(Container.GetCustom, "WholePrice", "{0:c}")%> '>
...returns "BC30455: Argument not specified for parameter 'strField' of 'Public Function GetCustom(strField As String) As String'."

and

Text='<%# String.Format("{0:c}", Container.GetCustom("WholePrice")) %>'

... does not have any effect, but displays the unformatted "WholePrice".

Once again, I realize no one may be able to help in this case, but thank you for any advice or suggestions. The 3rd-party documentation seems a little fuzzy on this subject to my novice eyes, but the relevant passages appear to be as follows:

<quote>
Catalog Template Properties / Containers:
GetCustom("FieldName"): Used to show custom field data in the Templates. This returns any custom field data.

Programmatically changing a control value within a given page:
This is useful if you wish to change a control within the template programmatically, for example for language customization.

Label myTemp = (Label) Page.FindControl("Catalog:ItemDetails:myWeight");
if(myTemp != null);
myTemp.Text="Weight(Test):";

The "Catalog:ItemDetails:myWeight" is the ID for Weight label control used in default.aspx. The "Catalog" is the ID control in default.aspx page for Catalog control and "ItemDetails" is hardcoded ID inside the component for ItemDetailsTemplate Template. "myWeight" is the ID for label inside the ItemDetailsTemplate Template in default.aspx page

Thanks again.

EDIT: I just got some help with this.

Text='<%#FormatCurrency(Container.GetCustom("WholePrice")) %>

does the trick.

SqlDataSource and Exceptions

Well, it appears that as they are hosted on different projects, you have not imported a reference to the webservice, and so, it can't see what code is sitting on another web server.

Is there any way know to mere mortal man to actually be notified of a data access error when using the CRUD operations of a SqlDataSource? I find having to use SQL Profiler to detect an invalid stored procedure parameter a bit much.
