Because you didn't set a width and so the browser is free to choose one ?

You're writing your own ajax ? You're opening another page that has the second dropdown ? How are you trying to set the selected value in this page, via the URL ?

This is from Chandrakanth.
I need some Guidance regarding Dynamic Generic XL Upload With Validation.
Can any one give me some suggestion for this Dynamic Generic XL Upload in C#.
That means in MY Excel sheet in non -specific fields that means...
In my excel sheet fields are not fixed it may be 5 columns,it may be 10 columns.
I have to do this excel uploading with validation ,, while I am doing this excel upload I have to map with stored procedure.. and column data types...
Developer does not involve on every uploading coding part...that means we have to facilitate to end user
Excel uploading any file regardless of fields and data types has to upload with validation...
We have to make general Excel Uploading ,,,,,, with validation using SSIS feature in SQL SERVER 2005
If u have any Idea(any other logic) to do generic excel uploading,,please share with me ...
Thanks in Advance

I'd just create a bar graph using one of the free tools that exist, or write my own. A bar graph is easy to draw.

Chris,
Can you show me how to do that with data from dataset.
Thanks

I'd expect you'd do it in the database. That's what the database is for.

Chris,
That is something I would have to do at the front end through the code.
To start with that is the thing I am unable to do and looking for some code to dra a bar graph from the dataset that I get from the database
Thanks

Now i am in a condition, Where I am just displaying the month names and numbers. There is a small issue. I need to get month names instead of month numbers from Oracle.
here's my query
SELECT Count(*),EXTRACT (MONTH FROM DATE_CREATED),EXTRACT (YEAR FROM DATE_CREATED) FROM MyTable GROUP BY EXTRACT (YEAR FROM DATE_CREATED) ,EXTRACT (MONTH FROM DATE_CREATED)
And the result is 3 columns. Count, Month(Number) and year
something like this
3 10 2006
Please anyone help to convert the month number to month name in oracle or C#. Problem is I cannot use the data formatting functions as this is a single number appearing.
Thanks for any help!!!!!!!!!!!!!!!

You mean the ON DELETE SET NULL option in SQL 2005? I don't think there is an equivalent in Access. You should probably run an UPDATE query on your foreign key field before your DELETE query to set any values related to this picture to NULL.

Hi all,
my project is based on inserting and retrieving video files (type :MPEG)
I'm using ASP.NET2.0 and SQL SERVER 2005
my question is how can I insert video files in the database????
bleave in your self
|
|
|
|
|
This question has nothing to do with ASP.NET. The ASP.NET part would be 'how do I upload video files'. You realise that unless you serve the video files without any other HTML, you can't serve them from the database ? It's probably better to store the path to a video on your file system. Having said that, you can store them as a blob.

No, you don't. You can't access any server control at all from Javascript. The code is accessing the html elements that the server control has rendered.
The server controls only exist on the server to create the html page. Once the page is created and sent to the browser, the server controls doesn't exist any more.
mr.mohsen wrote: how can i access to the selected value property of a dropdownlist control with javascript?
You can't. You have to access the properties of the html elements that the control has rendered. Use the selectedIndex property to get the index of the selected item, then use that to get the value of the selected item.
Example:
var sel = document.getElementById('idOfTheSelectElement');<br />
var value = sel.options[sel.selectedIndex];

When your server side code generates the script for the page, it can generate script to call the method in question when the page loads.
