Selecting Outside The Form?

Dec 24, 2008

I have a form that needs to add user selected items to a listbox. But these selections are done outside the form itself. So in windows explorer, the form pops up and then the user keeps clicking on files and I want these file names to be added to the listbox. How can I do this? in my case, as soon as I click outside, obviously the form loses focus. How can I "listen" to mous clicks outside?

VS 2008 - Selecting All ComboBoxes In Form

Nov 1, 2009

I need to select all the comboboxes on a form with a for each loop. I have about 19 comboboxes and I need to select each one. I tried to do
for each box as combobox in me.controls
But that gave me an error and i now tried this:
for each box as control in me.controls
if box.name.contains("ComboBox") then
...
end if
next
That selected only the comboboxes but the problem is i need to access some data that is specific to comboboxes (aka the selected item(s), if its blank) but those properties are not present since "box" is a control, not a combo box.

Selecting And Moving Multiple Form Controls At Runtime?

Aug 25, 2010

At design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?

Asp.net Mvc - Selecting A Single Row Using EF In MVC 3?

Oct 24, 2011

I am trying to get back a single from from a EF database model using the below line of code..

Dim _classRoom As classrm = db.classrms.Select(Function(b) b.Course_ID = _CurrCourse.course_ref)

Where classrm is the name of the entity and db is declared as a new entity. What I am trying to do is select a row from the entity based on matching Course_ID which in this model is a string. So that I can later use the variable _classRoom to get other items out of the same row.. However I am getting the following error:

Unable to cast object of type 'System.Data.Objects.ObjectQuery`1[System.Boolean]' to type 'Trial_Online.classrm'.

I have to preform similar tasks with several different Entities but if I get pointed in the right direction I can manage from there...

Asp.net - ListBox Items Not Selecting ?

Jun 27, 2011

I have a simple ASPX page with a listbox and a button. Listbox has about 8-10 items in it. After the user selects an item (listbox is multi-select) and clicks the button, I'm iterating through the items to get the selected one like so:

For Each Item As ListItem In lstLetters.Items
If Item.Selected Then
Dim LetterID As String[code]....

When I step through the code, I select the first item from the listbox. I setup a watch on the 'Item' variable. The code will iterate through each of the items -- but Item.Selected always reads 'False'.I double-check the page, and sure enough my item is selected on the form.What the heck is going on?

DataGridView - Selecting Row After Sorting

Sep 29, 2011

I have a datagridview that is bound to a dataview. I use a textbox to sort the list of data in the datagridview. Once the list is sorted I want to click on a row to populate the textboxes in order to update the data. Problem is once I sort the data I click on say row 3 and it pulls up the orginal data before the data was sorted in the datagrid view. For instance:

Before Sort:
1. betsy
2. james
3. john

After sort:
1. john
2. james
3. betsy

If I double click row 1 it will pull betsy info into my textboxes instead of john. I currently refresh my datagridview after every letter is entered into my textbox. I also reload my dataview and rebind the dataview with the datagridview.
