Populating A Listbox From SQL Server In Databound Formview
Oct 24, 2010I am "trying" to switch my form from SqlDataSources to ADO.NET data sources. So I have a DAL setup, and ObjectDataSources in my form referencing these DALs. These data sources are bound to the form's objects. So far so good. In the InsertItem Template of one of the form's FormViews I have a list box that I am trying to populate with a value pair (ID, TechName) from a database table and I get the following error:
"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." Apparently, one of the two workarounds involves programmatically loading the listbox. The code below shows one of my attempts, resulting in the above mentioned error:
Code:
Protected Sub TestFillDefaultValueInFormView()
Dim vInspectorList As DropDownList
If (FormViewHydInspection.CurrentMode = FormViewMode.Insert) And Not IsPostBack Then
vInspectorList = DirectCast(FormViewHydInspection.FindControl("DDlstInspBy"), DropDownList)
vInspectorList.Items.Clear()
Dim vInspectorDA As New DataSetHydrantsTableAdapters.TechnicianTableAdapter()
Dim vInspectors As DataSetHydrants.TechnicianDataTable = vInspectorDA.GetTechnician()
Dim vInspRow As DataSetHydrants.TechnicianRow
Dim vInspectorHT As New Hashtable
vInspectorHT.Add("0", "Select Technician")
For Each vInspRow In vInspectors
If vInspRow.TechID <> 0 Then
vInspectorHT.Add(vInspRow.TechID.ToString, vInspRow.TechName)
End If
Next
vInspectorList.DataSource = vInspectorHT
vInspectorList.DataTextField = "value"
vInspectorList.DataValueField = "key"
vInspectorList.DataBind()
End If
End Sub
I tried populating the listbox directly using the Listbox.Items.add() method (which is the way I have it now so I could continue solving other problems, and it works!) but I could not find a way to add a value pair. I did try:
vInspectorList.DataTextField = "Select Technician"
vInspectorList.DataValueField = "0"
but that left a listbox without any data.
DataSource Controls :: Populating Listbox With Directorysearch Result?
Mar 11, 2010I'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.

Populating A PDF Form With Data From SQL DB Table
Jan 4, 2010I'm writing an app (ASP.NET 2.0 w/ VB code behind) where my users complete a sign up process. Their data, such as name, address and phone info is stored in a SQL Server DB table. What I want is for them to be able to click a "Print Authorization" button that auto populates the authorization.pdf form and then let's the user print out the form to sign it.
How do I populate the Authorization.PDF with this info from the SQL table? Basically, I just need to know about putting the data on the PDF and then having it print. The file doesn't need to be saved, just populated with data and then printed. I have no experience with C# so the iText solution really won't work.
MVC :: Populating A Form From A Dropdown If Customer IDs?
May 4, 2010I need the simple task of populating a form from a dropdown if customer IDs.
The problem is I'm new to MVC and I no longer have events, so I'm not sure how my dropdownlist can have a postback event that does one thing, and my update button can have a postback event to do another thing.
Example, this only goes to the post action, so how does it know to load the customer or do an update:

Refresh A Listbox In One Form From A Second Form?
Sep 30, 2010this should be pretty simple but I can't find a solution. I spent a bunch of time, without luck, searching for an answer that makes sense (to me).
Here is the problem. I have an asp form in a frame (I know frames are considered evil, but this part is non-negotiable) This form has an asp:listbox that is tied to a SqlDataSource. A button on this form opens a second form that allows the user to add records to the SQL table that is bound to the SqlDataSource object (the source of the listbox in the first form) The thing is, that when the user closes the second form and returns to the first, the list box needs to be refreshed and I have no idea how to do that.

Aug 18, 2010I 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.

Forms Data Controls :: Bound Textbox Not Populating In Gridview?
May 25, 2010I 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?

Feb 11, 2010From the asp.net page, I would like to view the reporting services reports i.e. the .rdl files.I am using a reportviewer to access one of the reports as follows. Notice that I have hardcoded the name of the .rdl report.

Nov 11, 2010New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1:
userID
fname
lname
etc...
Table2
userID
categoryID
subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?

Mar 9, 2011My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
