Okay.Then you can debug the method by using,
debugger;
debug the code and try to explore ddl object so that you can find the issue.

Nice answer, but you forgot to mention that you must include jQuery script.

Hi All,
I'm about to start a new project that will query a database and return 6 possible combinations of result schemas and I'm trying to think of the best way to query and display the data on a single page. To clarify, there are tables in SQL that fit into one of six different schemas because we are working with six different systems that enter data into the database.
In a previous project, we were working with about 50 tables, all with the same schema. We were able to have standard queries, views and business objects. It was easy to use an objectdatasource and populate a gridview.
On this project, we want to display the data in a grid or other data control, and we only want to show the data from one table at a time. However, we aren't sure of the best approach for bringing that data into a single grid because the fields aren't consistent. Would it be a bad idea to construct a class with every possible property, use an objectdatasource and then hide and display fields in the grid? Maybe that's too outdated and there's a more modern way to handle the problem? One the other hand, I'm trying to avoid handling each schema separately. Does anybody have any suggestions of a better way? Any guidance is greatly appreciated.
Thanks,
Chuck

You could just set AutoGenerateColumns=true

Thanks Mark,
In the final piece of displaying the data that could do it. I'm wondering if my approach about building a class with every possible property, populating it from a stored procedure(s) and then displaying the collection in a grid is the way to go or if that's been replaced by some better way. Something about that doesn't seem like it's the best way. I'm might try looking into linq2sql or entity framework, but from my limited experience with them, I'm not sure if they offer an advantage.
Thanks,
Chuck

If the goal is the ability to display multiple schemas in a single grid then creating a class for every possible combination would be tedious overkill compared with AutoGenetrateColumns. Entity Framework does have advantages in CRUD operations, you don't have to write anything, and ORM. However, once again, if you only need to display the records, it would be overkill.

That's good advice. I might just take the simplest approach and see how it works before trying anything else that's more complicated. It's a faster way to figure out if it's the right solution.
Thanks,
Chuck

Hi
Thanks for your reply..
i found with the help of some articles that those dll's are satellite assemblies created with the help of resource file and because of App_Globalresources Folder not exists in previous versions of .NET Frame works, those compiled assemblies were used and also when delivering application to give as satellite assemblies is used.
so those dll's are satellite assemblies with the help of resource files.

How to convert total data in a page into crystal report

Hello Friends
I have created user control in which there are two dropdown and two textbox are present.Now i am adding this user control dynamically for multiple time on button click event. Now i want to take all the value from dropdown list. So please help me in this
|
|

Expose your dropdownlist as a public property of your user control.
public DropDownList myDropDownList = ddlOfUserControl;
Then, in your page use it as
string selectedValue = myUserControl.myDropDownList.SelectedValue;
|
|
|
|
|
It's not a good idea to expose controls by making them public. The client program will be able to change the value or even worse, clear the dropdown by calling myUserControl.myDropDownList.Items.Clear() which is not what you want. See my answer for a better solution.

Well, some times this might be required.
I totally agree, when not required, we can simply expose the portion which is required to be accessed.
But when we need, we can expose the DropDownList also. I had such requirement in my earlier project where we had to set the listItem values from Page.

There is not a single situation where it is required, you can always forward calls to your internal controls through properties and methods in the user control. Take your example, you could have created methods/properties that set the list item of your dropdown.

In your user control, create properties that expose the information you want. Like this:
public string SelectedValue {
get {
return dropdown1.SelectedValue;
}
}
And then from the clients, you can access the property like this:
string selValue = userControl1.SelectedValue;

Did you mean you've install Office 2010 on the server?

How to change the position of an applet on an asp.net page without reloading the applet? I tried to do it with the help of css but the applet starts its (startup) operation after the css style class has been changed.
I have a signed java applet. It gets some data from a client PC then a user clicks on a button inside the applet and it must trigger some changes to the web page.
For now after the button inside the applet was clicked the applet puts a new url to the parent window that is the same url but with a parameter "?results".
The problem is that even if if will find a way to pass data from applet to the web page with out the usage of url, the applet still reloadsd, for instance if I just change the class of style of the applet to change its position on the web page.
Maybe it is possible to store the data from the applet (hashmap) in RAM and then the applet would check if that data exists when it (or the whole page) reloads?
Thanks.
