AllDefinitions.UserProfileseverytime?I had a problem when the list was refreshed, and I set the datasource again, the listbox showed Definitions.UserProfiles instead of the display name that I set.when I changed to always using the bindingsource, everything worked fine.
Check out the simple code below :
[code]...
What happens is that when the Item2 is selected in the first listbox, the second listbox automatically changes its selected item to the Item2. This happens just the same with the other listbox.
I have a small requirement and that is as follows:
I am populating a ListBox using stored procedures and the ListBox is populated as follows:
lstItems.DisplayMember = "emp_name"
lstItems.ValueMember = "login_id"
lstItems.DataSource = accessFunction.getEmployees
The ListBox gets populated correctly. After it is populated, i have a CommandButton and on the click event of the button, i want to remove selected items from the ListBox. So in the click event of the CommandButton, i have written the following code:
lstItems.Items.Remove(lstItems.SelectedItem)
After selecting an item from the ListBox and when i click the CommandButton, i get an error as "Items collection cannot be modified when the DataSource property is set".
how i can delete items from the ListBox.

It's my first time playing with the DataGridView properly and I've hit a little snag...I need to display data in a DataGridView for ease of viewing, and I have a list of all the data. It's a list (of a structure), and I've got no idea how to do this. I can set the datasource as the list, but that doesn't work. I've read up on the topic but don't really understand. Am I forced to use classes not structures in this instance?
View 1 RepliesI have inherited a database that is moving to the web. Problem is that some of the string fields have html characters....
One example is....
"" without the quotes, IT WON'T SHOW UP IN HERE EITHER, trying something else. At any rate it has < and the > signs with text in the middle.
How can I escape any possible combination of html references.
SelectCommand="usp_getSingleStringData" SelectCommandType="StoredProcedure"

I'm using VBE 2008. I have comboboxes in my DataGridView which is databound to a BindingList(of T). For some reason, when the DataGridView is loaded via me adding data to the BindingList, the comboboxes show a value of 0 until they are refreshed. Simply a mouseover will refresh them to the proper value. Why do they not show the proper value when loaded? The non-ComboBox cells show the correct value immediately.
The only thing is that the ComboBoxes reference data from other BindingLists, so they may be slower in getting their data. Do I need to put some sort of delay in before the ComboBoxes draw? Why are they drawing with wrong data in the first place? Alternately, if I can't figure this one out, I may need to refresh the DataGridView after loading. I tried that, but the trouble is, as the data comes in quite quickly, the DataGridView ends up with an annoying "flashing" as it's continually refreshed.

View 1 RepliesEach time my webpage is loaded it runs a routine in the page_load event of the page behind which increments a viewcount by 1.
The problem I have is that the routine runs even if use refresh to reload the page.
How do I stop this routine from running if the page has been viewed by a particular user in their current session? [code]...
Can a data grid in another open form be refreshed by calling a sub routine? This app has a form with 2 data grids. When the user double click on one of the grids another form is opened that shows data details. After the user changes the details the user clicks a save button. We have placed this code in the Closing event of the the details form.
Private Sub FormParents_FormClosing(sender As System.Object, e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
FormParentsAndStudents.RefreshDataGrids()
End Sub
[Code]...
Can you tell us what additional coding is needed to refresh this data or if we are using the incorrect place to call this code from within the details form?
that my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="Button1" runat="Server" Text="Refresh" OnClick="Button1_Click" />
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">

I found that if you press F5 or refress from browser window, the last event fires again
example, I have clicked on a button, the button event is carried out normally, but if I refresh the page by pressing F5 key the same event is fired again.
The problem im having is that I have a table that when a user click on a button it adds a row to the table via javascript, which works fine. The problem is that if a user need to update other data the user click another button which refreshes the page and all rows the user created in the table are deleted. My question is what can I do to make the rows not to be deleted once the page is refreshed? I know some might think, just not refresh the page, but there is to much data that has to be displayed and a new query has to be generated to grab the data.

View 8 RepliesI have a DetailsView that looks just about perfect. The only thing is, there is one field that actually gets its information from another table. It is an ID field that is linked to another table in the database and I was hoping that there was some way to get that one field in the DetailsView to pull the information from the other table.
Is there a way to maybe add a + (plus sign) next to the PicklistID and then have it show the results of the other query? (SELECT TEXT FROM PICKLIST WHERE PicklistID = @PicklistID???)
UPDATE 1/11/12: The PICKLISTID in the table PICKLIST is not unique or a primary key so I cannot reference it from the SURVEY table. Is there a way to give these 2 columns a relationship so that I can just change my SELECT statement in my DetailsView to include the PICKLISTID?
UPDATE 1/23/12: I'm still stuck on this. I am not getting how to make this work at all.

how do you add information from another datasource into a cell in a data grid which has the relevant information i.e order_bindingsource grid which has the information order id, item id, quantity and cost per item.
The item id I have linked to the Productbindingsource but I also need the information to be shown cost per item which is in data source products.The item id is a drop down box with the items displayed what I need is when an item is selected I need the price to show up in the cost per item box.
I am trying to create an arrayList of people. The variables, or arrays are; first name, last name, age, DOB. I am wanting to load all that into one arrayList and dataBind it so it would look like [code] Loading it into an ASP DataList. SO Fname + Lname + age + DOB are loaded on the same line/index. Not sure how to go about this. I'm sure it's an index issue..but not sure the thought process to even begin to load these elements into the "0" element, then the "1" and so on. Not puling the information from a database, just preset arrays/arrayList. ANY suggestions? ( I have it so it is dataBound to one arrayList entry as in [code] This works fine. But if I wanted to add the last name to the first name on the same line...that's were I am not seeing the connection.
View 5 RepliesHow to declare a datasource?
View 1 RepliesIn one of my projects, I have this line of code that works:
Dim newCustomersRow As EyeBaseDataSet.HistoryRow
newCustomersRow = EyeBaseDataSet.History.NewHistoryRow()
In this new project I'm trying to get the same thing going, but I can't use the Row definition. I type the data set name and don't get an option for the tableRow. I don't know how else to word this, but I need to know what I have to add to the project to give me that control. In the working project it says "Class HistoryRow" and I went to the definition and it took me to the designer and showed me a Partial Public Class with System.Data.DataRow.
