That is because you are trying to add more than one column with the same name.
What is it that you are trying to do?
---
b { font-weight: normal; }

As Guffy said, a column named 'rating' is already part of your DataTable, and then in your code
dc=new DataColumn("rating");
dt.Columns.Add(dc);
You are adding the same column again to the data table, ofcourse it'll complain.
Good luck

Dear Concerned,
I want to create a property in my user control which i am creating in Web Control Library. I am using .Net 2003.
My question is that how I can create a property that will contain a dropdown list & will have five values 1,2,3,4,5.
The Programmer will be able to select one of these values at design time in his aspx page.
Please help in the form of code.
Thanks,
Fasih

Not sure what exactly you are looking for, but it sounds like you need to know how to populate a drop down list.
ddl.Items.Insert(0, "--Select--");
ddl.Items.Insert(1, "Value 1 or whatever");
This is how you hard code the values to be displayed, if you want to load 'em dynamically, then use a dataset or something as a datasourse for this drop down list. Look at the code below:
ddl.DataSource = ds;
ddl.DataTextField = "Columns_Name";
ddl.DataValueField = "Column_Name"; // note this won't be diaplayed
ddl.DataBind();
*NOTE : ddl = drop down list
Hope this helps.

Hi,
I have code that fires a stored procedure, to insert a new location.
I now need to add another insert, that inserts a destination into another table, using a trigger.
I pass the following variable to my location table : @LocationCode
I want to create a trigger, that everytime an INSERT is fired on the Location table, it should add a row to my Destination table.
Here is what I have to create the trigger:
<br />
<br />
CREATE TRIGGER DestInsert ON [Location]<br />
FOR INSERT<br />
AS<br />
<br />
INSERT INTO Destination<br />
(LocationCode, Destination, AreaCode, DeletedFlag)<br />
VALUES (@LocationCode, 'New', '123C', 0) <br />
<br />
Will this create a trigger for me, that adds the same @LocationCode variable I added for the stored Procedure to the trigger?
|
|
|
|
|
use..
Inserted.Locationcode
it will fetch the location code from inserted location
enjoy

Thanks, just one more thing.
Is Inserted a DB function, or does it gets the last LocationCode inserted?
|
|
|
|
|
It's a table that contains all the rows that were inserted when the trigger was fired.

replace
calInstDate.SelectedDate = DateTime.Parse(instdate);
by
calInstDate.SelectedDate = DateTime.Parse(instdate).Date;
and also use
calInstDate.VisibleDate = DateTime.Parse(instdate);
to show selected date if required.

If you want to partially update a part of the web page as oppose to all of it, and frequently, then you might want to take a look at AJAX. Code Project have a number of good tutorials at http://www.codeproject.com/Ajax/
