VS 2008 Pre-Load A Large Text File List Items In Dropdown

Oct 28, 2010

I need to load a large txt file that is in a fixed width format.

So having it in a DB would be more work to process that part.[code]

VS 2008 Dropdown Box Displays All The Items Previously Added To That Column?

Apr 30, 2010

The dropdown box displays all the items previously added to that column.

I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)

Problem:

Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.

How do I get it to do what I want.

Shorten Selected Value In ComboBox DropDown List For Display

Feb 21, 2010

I have a combo box that has a drop down list with long values in the drop down
Ex:

LB - Pounds
GR - Grams

When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows

LB - Pounds
GR - Grams

When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

Custom Control - Specifying Items To Be Added To List

Sep 30, 2009

I've created a custom control that I insert into my window with the following code
Code:
<controls:ListExpander Text="Class Diagrams"></controls:ListExpander>
The control in question contains several subcontrols, among others, a list. How can create the setup, so I can specify items that should be added to the list?

Code:
<controls:ListExpander Text="Class Diagrams">
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
</controls:ListExpander>

In which case the SomeItem objects should be added to the list in the ListExpander:
Code:
<ListBox Name="lstItems" Background="LightGray">
<ListBox.Items>
// Items should go here
</ListBox.Items>
</ListBox>
I'm quite new to WPF, but I suppose it's something along the lines of creating a dependency collection on ListExpander that takes object of the type SomeItem? I simply want to be able to give the control a few arguments which it can translate into items in the listbox contained within the the control.

Load Combobox Items Dynamically On KeyPress?

Oct 4, 2010

I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.

I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.
