I am using VWD with a page that includes a formview and gridview. At the top of the page is a textbox, with and ajax calendar extender where the user selects a date.
The gridview is filtered on this date. I would also like to prepopulate a textbos in the formview insert template with this same date.
I have a SQL Datasource populating a Drop Down List with Company Names. The Select Statement the Datasource uses selects Company ID and Company Name.When a company is selected from the list, there is a button on the page to continue processing with the selected company. On the press of the button, I want to set a session variable for the Company ID of the Company selected. This Company ID is obviously held in the Datasouce. Any idea how I get at the Company ID.My code will look like the following:Session.AddsessCompanyID", ????????????)where ?????????? represents the source of the Company ID.

2. Dropdownlist( Search for department)
3. Listbox( Populate staff name based on textbox or dropdownlist)

In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.

I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?
I'm creating a user control that enables users to search AD and add the selected names to a list (which is used to send mail lateron).
The problem is that the search results end up in the Listbox but all as the string "System.DirectoryServices.ResultPropertyValueCollection" in stead of the actual values.
I have no idea why.
This is my code:

I need to populate a text box from a stored porcedure call that does not have any parameters. I've made the database connection and am executing the stored procedure, but I cannot figure out how to set a text box value to the return value of the stored procedure. BTW, the stored procedure only returns one value.
View 2 RepliesHere is what I have tried:
txtCost.Text = string.Format("{o:c}", dr["Cost"]);
Here is the error I receive. How can I format the data that is coming from the data reader into currency format??? Also, is there a way to format it into currency without the dollar sign?

I'm looking for a steer on how to go about running stored procs efficiently.
I have a current requirement to populate a control, so I have all the specific data i.e the parameter value I need to pass and the control I want to populate, plus generic data such as SqlConnection etc.
I'd like to be able to call, say, "MyStoredProc". MyStoredProc would contain all the necessary information to run the proc, but then pass onto a method, say, GetSpData, which contained all the generic stuff about running stored procs.
Then when setting up MyStoredProc2 I could do without repeating a lot of the original function
Im I barking up the wrong tree or is there an efficient way of managing this kind of situation.

View 5 RepliesI want to write an independant class that can fill the fields in an HTML using asp:textbox. I have a class that can pull information from username and send it back to the webform. I would really like to use another, or possibly the same class, to take that data and send it to asp:textbox.text to populate the fields.
My issue is I just can't seem to find anything in my books, or online, that would help me let the class know the form is there, and that it has those fields inside the html code.
Are they objects that I could potentially pass into a new class constructor that I could populate that way?
After accomplishing this my next step would be to use this to create a class to send an email with some of the fields being passed from the form to help fill in the email.
Is it possible to populate a listbox from a textbox on another form? Ive tried searching google but have had no luck.

I'm populating a grid view with data from an SQL datasource. The database has a a list of performing artists and lots of details. The gridview initially, shows the ArtisID (Primary key) , and artist name and music style. So far this is all simple and easy. This is done.
Now I want to be able to click on the ArtistId (Select Column) and move the customer to another page where I show indepth details about the artist. How do I do this???
In Vb.net I had a 'Celldoubleclick' event, and I redirect the client. But how do I accomplish the same in asp.net? I already have the primary key value
primekey = datagridview.selecteddatakey.value

I'm trying to use a javascript Date and Time calendar in my Insert and Edit templates in a Detailsview that is bound to SQL Fields. The reason I am trying the javascript date time selector is that I need to have the date and time, the asp.net one is just the date part.
I tried using it with an asp:textbox on just a plain aspx page and it works like a charm, however when I add it to the detailsview i keep on getting the "Error: Object required" am I missing a step here? That and seeing as I'm using a site master page where exactly do I put the:

I have written some vb code that inserts whatever has been written on my page into an Access database. Only problem is VWD throws up an error saying that the syntax of my SQL statement is wrong. I am 95% sure that this statement is correct because when I saw the statement in Text Visualizer and tried that statement in MYSQL the data went in perfectly.
I have pasted the code below:
