Ajax/javascript problem

I was on a session by Stephen Walther where he introdused client side ajax by a web service,
the example was pritty simple:

<table cellpadding="0" cellspacing="0">
        <thead>
	    <tr>
		    <td>		    
		        <asp:Button                                                                                                             
				    id="btnShowDetails"  
				    runat="server" 
				    Text="test"
				    />
		    </td>		    
	    </tr>	</thead>
 <tbody id="myTbody">
	    </tbody>
</table>

    </div>
<script type="text/javascript">
function showText() {
            AjaxWebService.MyWebService.Product.getText(showTextComplete);
        }

        function showTextComplete(result) {
            $("myTbody").html(result);
        }

The web service return a simple string like "<table><tr><td>This is a test</td></tr></table>".

The problem is in the function showTextComplete, I always get "Microsoft JScript runtime error: Object expected",
it's the $("myTbody") that's wrong. When Walther showed it, it worked fine.

So what em I doing wrong?

Thanks
Thomas

try

var myTbody = $get("myTbody");

myTbody.html(result);

or

myTbody.html = result;

I didn't get any requirements for the signature

var myTbody = $get("myTbody");
myTbody.html(result);

gives me the objekt, thus the objekt does't support the method .html(..)
(I can acully drop the "var myTbody = $get("myTbody");", since it findes it without it.)

I thought maby I could use

myTbody.innerHTML = result;

But this gives me a "htmlfile: Unknown runtime error" exeption Frown | :(

Yes, and it is OK with reslut = ""<table><tr><td>This is a test</td></tr></table>"

Well then create a string variable and set it to the result.

If you have your html object such as a div tag. And a string that is your innerHTML or innerText there is no reason why that shouldn't work.

Select a specific row in a gridview

I have a gridview bound to an ObjectDataSource (DataTable).

DataKeyNames = "LocationId"

How can I find the row in my gridview with that LocationId?

I would like to have the row displayed (could be on a different page in the gridview) and selected after the postback.

Is there an easy way to do this?

Dont know is this the easy way or not, but its kind of old C Language way... Smile | :)

int SearchRowIndex = -1;
foreach (GridViewRow gvRow in GridView1.Rows)
    if (gvRow.Cells[0].Text == LocationID)
    {
        SearchRowIndex = gvRow.RowIndex;
        break;
    }
if(SearchRowIndex >=0)
    // Do Programming... with GridView1.Rows[SearchRowIndex]

Thanks for the help. But I simply removed the paging and put the grid inside a div with a side scroller. Then I set rowstate to selected on rowdatabound if the row was the row I was looking for.

Thanks for the reply though. After thinking about it, I didn't like the paging anyway. It just makes it more difficult to find records.

Hai,

Is there any way to bind a dropdownlist with a nested object collection without looping through the collection and adding as list item?

Regards,

Why?

Just iterate through the array or generic list or whatever your object is. Actually, iterating through a datatable or anything else is always more efficient then calling a control's databind method.

Hai,,

One more thing,why is iterating through a collection is more efficient than calling a databind method,this is just for my knowledge,what happens when an object is bound to a datasource?

Both does the same. But data binding is made to support a wide audience. So there will be extra checking before data is added. When you iterate the collection, you are directly adding data to the control. But this performance difference is not noticeable.

Creating a Demo Webpage using ASP.net

Hi,

I am creating a demo ASP.net web page application which will be installed on client place for 30 days.

I want my ASP.net application to stop working after 30 days.
I don't want to reply on system date because user can always trick the application by changing the system date of Web server.
I guess I will not have access to user system hard disk and registry because application will be running in IIS and it doesn't have access to them.

Do you think if there is any other way I can manage trial version of my application.

Thanks in Advance

If you have faith in the cause and
the means and in God, the hot
Sun will be cool for you.
