Sep 18, 2010
I am beginner of asp.net and c#Currently i doing appointment website and need suggestions/ ideas. I have create a simple web form with Calender Control as picture below enable users to select date and time. At the calender control, i have set that users can only select tuesday and thursday every month using DayRender. After that i put a DropDownList to display the time.Next step, i want to store the data into database, for example UserA make appointment on Date 21 September 2010, Time 1100 and make it unavailable for other bookings. When UserB makes appointment on same Date and Time, it will display information that the slot is booked/unavailable. To implement this, what approach should i take?
I need to check for duplicate records before inserting them into the SQL database.Thus I have the following codes:

but there are error message. "Object variable or With block variable not set."
I have got a page in which there is a file upload option where I have to upload/import the csv file. What I want to do is to check if the correct format of file is uploaded for instance if any other than csv file is uploaded, the system should give an error message. Also what I need to do is to check certain fields of the csv file for instance there are some mandatory fields in the csv file which should be there like name , postcode, How can I check that these fields are not empty . After performing these task, the system should automatically upload the csv file onto the sql sever 2008.
When I will click on gridview cell then it should open a pop up aspx page on which appointment details will be asked that I will store in databse. So with javascript how can I do this ?

I am trying to create an outlook appointment from an ASP.NET web site version 2.0. I am making use of the interface Microsoft.Office.Interop.Outlook to create the appointment. But my exact requirement is to display the body (description) of the appointment in HTML format (which includes images, links etc) instead of plain text. The only methodI can see in the appointmentItem is 'body'. This method only writes the plain text not the formatted HTML body. So is there any alternate approach to format the description (body) of an appointment?
As the title states, how can i stop two users from booking the same appointment time.
Example, two users logging, on there screen they can both see that a 1pm appointment is available. They both try to book themselves into that appointment time.

I'm populating a DataList using the IDataReader object and it works fine it the reader contains data. If the data is not present it displays nothing. I want to capture that situation and insert a verbiage such as "No data" or something like that. I've tried to test the datareader for various conditions such as Null, String.Empty, or plain " " but nothing worked. Is there a way to make this happen? Below is my code sample for your review.EJM.Note: It has to be done programatically as I'm building this for a web part.
how to check if a particular data in the database already, for example, i want to check if a username already exist in database, then the user cant choose that username.
I am using seperate buttons to control whether edit and delete row linkbuttons are enabled or not on the GV. When I click a buton to enable the edit linkbuttons on the GV and then click a linkbutton for a row that puts it in edit mode. Then if the Delete button is clicked I have code that disables the edit linkbutton and enables the Delete linkbuttons. But, if there is a row in edit mode and the delete button is clicked, the edit linkbuttons disappear and the delete buttons appear (as expected) but the row that was in edit mode does not have a delete linkbutton in it and the row is still in edit mode with no update/cancel buttons. When the delete button is clicked, if there is a row in edit mode, I need to cancel any edit modes in any row.
I'm using C# and SQL Server. I have one gridview which contain 3 columns "ID, COMPLETED (either yes or no), BY (adminID that completed)" and adminID can be null.
If user selected "yes" in COMPLETED column then how can I make sure that adminID in BY column is NOT empty or adminID entered is EXIST in database.
I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.
I have some controls on the asp.net page that can be required on certain senario and can be not required on others.
So we enable/disable them dinamaically depending on the current transactions.
Now I am thinking of a way where I can check the required field by Javascript on the click event of save button. Remember control not be required at all time.
I am using a DetailsView control to allow for updating a user record. Is there a way to check if the values are actually updated/changed when the update link is clicked. I know there are users, who would click the update button rather than the "Canel" even if there are no changes to the record. So, how do I check if any value has been updated when the update link is clicked. The DetailsView uses a SqlDataSource to populate the DetailsView.
i have code to update multiple rows in a gridview. What I want is that if the row value is = 1 in the database then the row is checked otherwise it's not. I've put some pseudo code in below to illustrate what I want to achieve.
