Its now working perfect.  I think the problem was that I turned the AutoGenerateColumns to "false" because after changing it to "true" it worked.
Thanks a lot for all the guidance you've given me.

Forgive me for being confused here, but this actually won't work if you want to keep adding to the datatable based on multiple selections from the textboxes, listboxes and dropdownboxes - right? This will only populate the datagrid once and then re-populate it on each click of the Add button?

Hi,
I'm looking for a control that does exactly the same as the control used on The Code Project for setting newsletter topics (see http://www.codeproject.com/script/Membership/Modify.aspx tab "Newsletters").
The control, when not selected, shows a comma separated list of newsletter topics. When you click the control it comes up with 4 columns of checkboxes in which you can select and deselect the newsletter topics you're interested in.
Any clues?

Thank you.
You wouldn't happen to have some html / ASP.NET markup would you (especially of the controls used within the DIV)?
I guess the "Hide/Show Div on the click on TextBox" has to be done with Javascript (to prevent a postback)? A small sample script would help a lot.
Thanks for your help.

You can do it using simple JavaScript.
Here is the sample javascript :
var counter =0;
function ShowHideDiv()
{
var DivID=document.getElementById('MyDiv');
if(counter == 0)
{
DivID.style.display ="Block";
counter=1;
}
else
{
DivID.style.display ="none";
counter=0;
}
return false;
}
Note: You can also do it without using counter, just check div visibility when you are checking the counter.
Hope this will help you

I have a treeview in my form. I need to get the nodes count of the treeview using javascript. I know it is possible in code behind. But I want to do it in javascript.
I used the following code,but getting an error that "controlid.Nodes.length" is null or not an object.
var controlid = document.getElementById('ctl00_MainContent_CreateWizard_UnitsTreeView');
var nodecount = controlid.Nodes.length;
alert(nodecount);
Any idea how to get the count of nodes? Please help.
Thanks,

Why do you require this using javascript.
treeview renders nested tables. So you need to use javascript to count tables.
why dont you count in the server side and store in an hidden field ? 
|
|
|
|

The treeview is rendered as a table, so there is no easy way to get a count of nodes - the nodes are actually table rows and cells.
You could apply a css class or other attribute to the nodes in the code behind when you are creating your treeview - then use javascript to count the number of elements with that class - very simple if you use JQuery.
Are you adding or removing nodes dynamically with javascript? If not then you could just count them as they are added server-side and embed them in your javascript when the page is rendered. This[^] post will show you how to embed asp.net variable.
Hope that helps.

You have to read that image in a byte array.
I suggest you to search on google, you'll find many helpful articles.

No, he doesn't. He's stored a path, he can just pass that path to an img tag.

Hello,
I suggest you use "Asp:Repeater". Put img in the container and then bind the img source to your database.

here is my query and i use it for making a crystal report when i run it in database MS Access it show the values but same query when i run it in sql server it show error "The text,ntext and image data type cannot be compared or sorted except when IS NULL or LIKE"
there are its datatypes
TotalSale int
Price money
Category Text
Transaction Text
same datatype used in sqlserver and MS access. Plz help
SELECT Sum(b.TotalSale*b.Price) AS total, a.Category , a.[Transaction]
FROM TransactionType AS a INNER JOIN CouponTransaction AS b ON a.TransactionTypeID = b.TransactionTypeID
GROUP BY a.Category,a.[Transaction];
|

You can't GROUP BY a field of type text.
You could cast Category to a varchar, but that would not perform well.
Are you sure that the type text is the most appropriate for your data? A varchar might be much better and your GROUP BY would then work.

thnx Nigel now its working when i change its datatype.
again thank u very much

Dear all,
How can I connect to an Oracle database under Linux from a ASP.Net Web (intranet) application to be hosted on IIS. To summarize the platform is as follows
IIS on Windows 2003 - Web Server
Oracle 10g under Red Hat Linux - database (Note: database is on Linux platform)
Application has been developed in ASP.NET in Visual Studio 2008.
What all settings do I need to make to make this application connect to Oracle.
Thanx in advance.
|
|
|
|
|
Add OracleClient.dll and use OracleConnection object.
Just pass Username and password with Datasource .. And I think it will connect.
Let me know what problems you are facing ?
I think only writing correct connectionstring will do everything.
