Why does this not work, where itms is a List(Of Item)?
Error event triggered on the line: Me.uxDropDown.DataBind()
DataBinding: 'Project.Item' does not contain a property with the name 'Text'.
In .Net 3.5 and VB.NET VS2008..How to set the DataTextField property in this link: url...Now update the page to build a list of TechnologyDescriptors and to attach the collection of TechnologyDescriptors for each control. For each control, set the DataTextField property to "TechnologyName" (to map it to the TechnologyDescriptor's TechnologyName property). This will ensure that the technology name will appear in the control. Then set the DataValueField for each control to "Description" to map the Description property to be the associated value.

i am trying to create a list of list in that i would like to work on multiple accounts at the same time. lets say i have 5 accounts. every account has a seperate name. each account has a few fields. so i though of having a list of bookkeeping (with 5 accounts) and a list of accounts (with expense, income, tax, status, etc as fields). [code] and if the idea of using list of list works how do i loop through both lists.
View 6 RepliesI have a grid populated from a list. Now there are particular properties in this list that I don't want displayed on the grid. It displays all of the columns perfectly, then adds 2 others I didn't originally have on the grid when I constructed it in designer mode. I have removed them after the binding with DataGridView.Columns.Remove("ColumName"). However, is there a way to prevent it from adding these beforehand, or is this the only way?

I have a DataRepeater that needs to display individual items from a List (Of T). The missing link between them is a BindingSource component.Everything works fine, i.e., the DataRepeater displays list items correctly, and I can add and delete items, even change using the TextBoxes on the DataRepeater.
The problem is that when I change the value of an item in the code, it doesn't get reflected on the DataRepeater. Only when I click a button on the form which executes this code:myBindingSource.ResetBindings(False)
I have a list box which is containning diffrent groups from database. On the form i have multiple controls like checkboxes, text boxes and so on.

I use the data binding mode to fill data into a list box, that is just fill all of the data in the table. if I want to group one of the table column and only display it in the listbox, how can I get this done? I know how to add a getData query to my table adapter, but how can I bind that new datatable to the list box at runtime?? cuz I need to put the data binding mode information in before I run the application and in the binding mode is no way to choose that getData query.

I'm having trouble with some Silverlight functionality. My goal is to get some data from the database and display it in my grid. Sounds simple, however, there are 7 columns that are always going to be there.
The rest of the columns depends on the account. There could be 2 (called Actions) associated with a certain account, compared to another account that could have 5, and the action names can be completely different.
I have successfully been able to return a list of all the possible actions for the given account, and then adding the columns to the grid in the code bihind(VB), and I can bind my data to the grid for all the columns that are already known. The way I store the item's actions, is a Property of type List. My problem is finding a way to iterate through the actions list of the Item object in order to bind those actions to the grid.
VB 2008 .NET 3.5. I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment.
My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc.
I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment."
In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use.
I have tried a few ideas, but none of them work properly.

i am trying to put the contents of a listbox into an array using listcount so i can sort and manipulate the data in the listbox using linq. Everytime I try to use list**** it errors and tells me that listcount is not a member of systems.windows.forms.listbox It also gives this error or list. Here is the for loop i am trying to use to put the data into the array.
[code]
For i = 0 To displayListBox1.Listcount - 1
sorting(i) = displayListBox1.list(i)
Next
[code]
i dim'd i as an integer and sorting() as a string early in the program as class level variables. displayListBox1 is the name of the listbx containing the data I need to use in my LINQ inquiry.
I'm trying to learn how to work with Collections list. In the past, if I wanted to create a list I would use an array and then save it to a text file after I was done manipulating the data via CSV.how to save things of different types to a list such as:
Name, Birthdate(as date), Salary
I know how to do this in an array but all the synapses aren't firing with the "new to me" collections list as collections lists are hard typed....

The datagridview also contains a counry-column allowing the user to choose the country of the client.Unfortunately, databinding of comboboxcolumn does not seem to work if an own business class is used.

View 3 RepliesI started programming in VBA, then graduated to VB6, and I am now using VB.NET 2008 Express.I have read, in the various posts, that I should keep Option Explicit and Option Strict both on, in order that I use correct VB.NET code and not VB6.I am trying to do that but am totally confused with the results of one of my programmes that was running perfectly with Option Strict off, but now advises:Option Strict On disallows late binding. To me it appears that I am using early binding, but to be honest I am not clear on the binding situation. I have checked through a number of google items, and a number of this Forum's items without seeing the light.[code]
