I'm trying to export the details in my datalist into a PDF file by using this third part program called Itextsharp. However, I'm encountering problems in generating the PDF as it keeps giving me the "Object reference not set to an instance of an object" error which points to my "htmlparser.Parse(sr)"
I been trying for 2 hours now to fix this problem however no progress. Does anyone here have experience in Itextsharp?
Here is the code that runs the export to PDF command
Protected Sub Button15_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment;filename=Resume.pdf")

View 1 RepliesIm having problems getting data out of the databse and checking a checkbox if the records are there. I have two Records in my access database:
IDItemIDLocationIDInStock
1544MainWarehouse900
2544NewLocation100
3544StrongRoom200
WHat i have done is Create a SQL string that takes the ID 544 and searches through database. If a match is found the the same as the LOCATION name on another Table then it takes the LOCATIONID (it will be the ID, but not at the moment) and puts it into a listview along with its IN STOCK.THe location Table looks like so:
IDLocationName
3MainWarehouse
4StrongRoom

View 2 RepliesI am creating a Microsoft Access 2003 database which will be using Visual Basic code in the backend.I have a form called frmReports. On this form are three option groups consiting of checkboxes. What I want to happen is if one of the checkboxes is checked, then the other two option groups are made invisible.
The context of the problem is a teacher is reporting on pupils. If a pupil is marked as being absent from class, the other two option groups (Behvaviour and Homework) disappear as no other information can be input.
My VB.Net project is connected with MS Access. Whenever input in VB, it will save in Access.

The code works fine for TextBoxes and ComboBoxes, but, for CheckBoxes and RadioBoxes I don't know what to put instead of .Text?
I am trying to access the checked state of a CheckBox from a BackGroundWorker thread. I am utilizing properties and it seemed to work just fine. However, I'm using 10-15 CheckBoxes and I think using the InvokeRequired property would probably be best. I've looked over JMC's thread that talks about how to access controls from the worker thread a bunch of different times and I can't seem to grasp the concepts. When it comes to the InvokeRequired property, I suppose I understand why it is needed. But I'm not sure if I understand it completely.
From the example that JMC provides:
vb.net
Private Sub ResetTextBoxText()
If Me.TextBox1.InvokeRequired Then
Me.TextBox1.Invoke(New MethodInvoker(AddressOf ResetTextBoxText))
Else
Me.TextBox1.ResetText()
End If
End Sub
If I'm not mistaken, this tells us that if invocation is required to access the control, then we access via the MethodInvoker if not, then we just access to directly? So, if I need to check the checked state of a check box, I know I can just put a conditional statement after the Else line if I can access it directly. But, if I can't how would I use MethodInvoker to check the checked state? And then, when calling it from the worker thread, would I just call the sub?
I have been searching around the web for a solution to this issue but have come across nothing so far.Basically I have a table as shown below, which I made up of ItemTemplate fields and is populated by a DataSet from my database. It shows brands to the user of which they can then click and go onto another page.I need to add another option to the table called "All Brands". Thus then I can use this to go to a page showing all the brands.However I can not seem to easily add this into the DataList.

I am completely Goggled out on this one. We currently have a datalist consisting of rows of data for our company. What I need to do is to add a link into the individual cells of a particular column called candidate profile. The link will be View Notes. When that link is clicked, I would like to have a new row expand right below the existing row to allow the additions of comments in the empty row. When the user comes to the page and there are existing comments for the row of data, have it expanded and give the user the ability to expand, or close the comments as they see fit. I also need to figure out the best way to allow the user to enter in the comments as well.

how I would put a maximum of rows in a datalist. I have the program reading from a db and I just need to limit the amount of users in the view.

Is there a method for this? P.S. I put this here because I know that this is more of a vb.net code oriented question(limiting amount of data shown by an object)
View 6 RepliesI wanna show some values of variables (about 6) inside item template of a Datalist. let's say if i have
Dim A As String = "hello world"
I wanna show that inside the Datalist. Dim A needs to be declared on Page Load or in a method somewhere .. coz the source is the database,so i can't just declare as public const on the top of the page.I tried this in Datalist but i won't work as expected.
<%= a %>
I also tried putting that different places like ItemDataBound or Page init. it won't work if the way i did was wrong.In the datasource of Datalist is a datatable with other data. So it is like i am having more than one source for Datalist. Is there any way around other than putting that Dim A inside the datatable?

View 1 RepliesI have a datalist control that is not retaining it values during postback when the control causing the postback is outside of the update panel that the Datalist resides in. I have verified that viewstate is on for that usercontrol as well as all its parent controls. My basic situation is that I have a Datalist that contains a user control on a page. When the user selects several rows in a grid and presses a button, a datatable is filled on the backend and assigned to the Datalist which has its item template set to the UserControl.
On ItemDataBound I set specific properties in the control which customize the messages on that control to the specific item. This is then popped up using the AJAX Control Toolkit Modal Popup[ Extender. When the user presses Save the whole page posts back. Data is collected from the user controls and saved to the DB and the popup disappears. The issue I am currently having is that the DataList has 0 items when the save button is pressed instead of the appropriate number. THis issue just started appearing after we upgraded from .NET 2.0 to .NET 3.5.
