Databinding In Datalist Control?
Jun 13, 2011
I have a table called Sort with columnds sortID and sortname. I'm displaying my results in a datalist. I also have a table called Colors with colorid, sortId and shade. On my display I am selecting the results from the Colors table. But for the
SortId column I just have a number. Each sortId already has a sortname in the database. How do I get it so that the display page displays the sortname rather than its corresponding sortId name. Here is what I have: Sincerely, Computergyrl

I 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?

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")

I'm creating a composite user control and trying to exposing the controls as properties so that I can databind them from the form that I drop the user control onto. One of the controls I'm trying to expose is a combobox and I can't seem to figure out how to expose this combobox to the designer. I'm trying the following code that I've cobbled together from what bits of documentation I can find but so far no joy.
<Category("Data"), Bindable(True), _
Browsable(True), EditorBrowsable(EditorBrowsableState.Always), _
DesignerSerializationVisibility(DesignerSerializationVisibility.Visible), _
AttributeProvider(GetType(IListSource))> _

I have bound TextBoxes. When I edit anything, I have to move to the next or previous record before calling the Update Method for that record to be updated. With my DGV, I use
vb
Me.dgvSalvageListing.EndEdit()
and it will update as expected. So, how would I do something similar to my Simple Controls?

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.
<asp:DataList id="TypesList" runat="server" Visible="true" RepeatColumns="3" Width="100%" ItemStyle-Width="25%" ItemStyle-HorizontalAlign="Center">

I've run some code which extracts data from a database and presents it into a Datalist. It works fine when the script is on the aspx file, but when I transfer it to a code behind I get the following error
Compiler Error Message: BC30451: Name 'showIt' is not declared.
(showIt is the ID of the Datalist)Obviously, the Datalist markup is in my aspx page, and the script is in the code behind .vb file.As I say, it all works when the scripts are all on the one .aspx file.The code in the code behind is: (I've skipped the SQL and connection strings to keep this post concise)

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.
