Hittest - Dragging And Dropping Data From A Combobox To A Datagrid

Sep 24, 2011

I am dragging and dropping data from a combobox to a datagrid. I'm using VS2010 VB for a windows app. My problem is that the DragDrop event for the datagrid gives x,y mouse positions that are relative to the physical screen that I am using, not the datagrid. So when I use hittest to calculate the row and column the result is out of the bounds of the datagrid. If I manually drag the form around the physical panel, the x,,y coordinates on the dragdrop event chage accordingly. This is really strange.

VS 2008 Dragging And Dropping?

Jun 22, 2009

Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.

I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.

I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?

[2005] Data Grid View - Hittest

Jan 12, 2009

I have a custom made tooltip form that displays when the user moves the mouse into a cell on a datagridview using the cellmouseenter event.

The tooltip pops up right away, so the user has to move the mouse away to make the tooltip disappear (the tooltip is kind of big, thats whay i had to custom make it).

what i want to do is add a bit of a pause inside the procedure that displays the tooltip.
What i came up with was this:[code...]

VS 2005 - HitTest Rotated Rectangle With Four Points?

Jul 20, 2010

I'm making a game that needs to hit test a Rect object inside 4 points that basically forms rotated a rectangle. This means I can't use the Rect class's IntersectsWith function to hit test. So my question is: if I have 4 points that creates an imaginary rectangle of any orientation, how can I tell if another rectangle is inside the "fence" so to speak?

IDE :: VBExpress 2010 TableAdapter Configuration Wizard - "Refresh The Data Table" Option Dropping Value?

May 17, 2010

I am using the TableAdapter Configuration Wizard and under Advanced option I click on "Refresh the data table" and carry through to the end of the wizard. However when I run my code and want to update the dataset on the form I get the error message "Update requires a valid Update Command when passed with DataRow collection with modified rows". So, ok, when I look back at the Dataset with right click and configure I find that that the "Refresh the data table" under Advanced Options is no longer ticked, even though I had ticked it before and finished the wizard. Somewhere along the line the tableAdapter is losing this value.

Draggin And Dropping A Picture Box?

Oct 15, 2009

I'm running this on Microsoft Visual Basic 2008 I want to make a program with 2 forms, one with buttons, the other that will just hold picture boxes, which are created when those buttons are clicked. Once those picture boxes are placed on the second form, I want to be able to drag and drop them to move them anywhere on that second form.

I have it "working" as of right now, but it's really glitchy. Almost as if it can't keep up with my mouse movement. But I'm not moving THAT fast so I can only assume that something is wrong.The buttons work so I won't post that code here but the following code is for the second form and what I'm using to control the picture boxes.

Public Class Form2
Private counter As Integer
Private boxCounter As Integer
Private list As New ArrayList

Combobox To Select 1 Item Datagrid?

Mar 6, 2012

I'm trying to create a Select Distinct query, but i'm getting stuck with either an empy combobox either a filled combobox that displays all the doubles.or a message "System.Data.DataViewManagerListItemTypeDescriptor"

I have a form (form5) with 1 combobox and 1 datagrid.The datagrid loads 5 collumns "ID", "firm", "Fname", "mname", "Lname" The collumn "firm" will have some double firms with people in the other collumns ID Firm Fname Mname Lname1 AA John N West2 AA Jim L East3 BB Harry Sick Long4 CC Barry N Klote etc.I would like to select the firm from a combobox and filter the datagrid so that it only displays the selected firm and the people that are registred here. Furthermore i want the combobox that i use for selecting the firms to lose the doubles. I can load the datagrid and load the Combobox, but selecting is only pointing to the record (highlights in the grid) i choose and doesn't filter. Is there anyone that can give me a clue on how to solve this.

Private Sub Form5_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'Kjelpasser2012DataSet.Employees' table. You can move, or remove it, as needed.

This code produces a ComboBox that contains a DataGrid with two columns and seems to look fine. Although when you click on the ComboBox and select one of the rows in the DataGrid the selection in the ComboBox doesn't work properly. (It just shows the colum headers.)

VS 2008 Datagrid Combobox Woes?

Jul 16, 2010

This is probably a really easy question but i cant seem to find an answer anywhere.I've got a datagrid in which the first 2 columns are comboboxes.I have them populating from 2 different datasets but what i need is for the second one to be filtered, depending on what is selected in the first.How is the best way to pass the selected value from the first combo to the query in the second?On a related note, how can i set the combos to values i pull back from a query?Basically I'm running a query to pull back a load of information that has been previously entered and then populate the grid so that it can be viewed/amended, but i cant seem to set the value (or the display value) to what i pull back, even when it appears in the list of options in the drop down.

VS 2010 - Any Way To Filter DataGrid Using ComboBox?

Nov 6, 2011

Kinda new to working with wpf apps (and vb.net). Looking for a way to filter a datagrid using a combobox (to select the field that the user wishes to search) textbox (to input search terms for specific records). The datagrid loads fine as does the combo containing the fields, however my filter simply does not work.

Code for loading data (works fine)
Dim obj = Me._dataManager.Collections.ReturnCollectionByID(tableSelectionCombo.SelectedItem.TableID)
Me.DataGrid.ItemsSource = obj
obj.Load(New DataManagementDataRequest(Nothing, Nothing))

Code for filtering (not working)
If Me.searchTxt.Text IsNot Nothing Then
obj.filter = selectFieldCombo.SelectedItem.ToString Like searchTxt.Text.ToString
Else
obj.filter = ""
End If
