VS 2010 - Application - Datagridview And Textboxes - Add (on The Dotted Line) An Performclick Action
May 28, 2011
I am building an application where on a form is a datagridview and textboxes. The dgv and tb are bound to the same table. I am using the dgv to have an overview of the records and the tb I use for editing. Selecting a record programmatically in the dgv is no problem, but the textboxes have to be filled with the same record. Here I have added my code to this far.
If OuderID <> 0 Then
'select the row
For i As Integer = 0 To dgvOuders.RowCount - 1
If dgvOuders.Rows(i).Cells(0).Value = OuderID Then
[CODE]...
I am stuck right now. I want to add (on the dotted line) an performclick action, but a dgv doesn't have a performclick action.

Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

I have searched for this, and not been able to find any examples where someone has done this. I'm trying to add a new line into the cell of a DataGridView so the text appears on 2 lines (of the same cell). Here's some code to explain what i'm doing:
Dim DS As New DataSet("aa")
Dim tbl As DataTable = DS.Tables.Add("bb")
Dim xRow2 As DataRow = tbl.NewRow()

I have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

1) Lets say I have three textboxes: TextBox1 TextBox2 and TextBox3.
Public Sub loopthing (ByVal input1, ByVal input2, ByVal input3)
For i = 1 To 3
TextBox(i).Text = input(i)[code]....
I know that the (i)-thing will not work, but my question is if it's possible somehow to set the three textboxes text to different variables using only one line of code (Like my attempt above).
2)How can I do so that when I click a tabpage on runtime, a certain textbox is highlighted and ready to write without a mouse-click?
I've tried the tabpage's GotFocus- and Enter-events, and writing
TextBox1.Select()
there, but it only works the first time I enter that spesific tabpage.

How can I know if my query have deleted a row or multiple rows? I have a listview with items. Now, when user deletes an item, I need to remove it from the listview but only if the delete query was successful? I thought of rescanning the table for the existence of the record but that looked quite wasteful process.

I have a child form in an MDI application with a datagridview comboboxcolumn. I'm filling it with string values. When I load the form independently of the parent, I am able to set values for the comboboxcells. But when the form is loaded as part of the MDi application, with the same exact code, the cells are empty.

I have a problem drawing dotted path lines, with evenly spaced dots: I want to be able to draw evenly spaced dots along a path line using points in an array, My issue is not with drawing the path line, with dotted lines, this is easy, but with the spacing of the dots at the start and end of the path line.
In the example I have created, I create a square with 4 points and draw a dotted path.The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have.I have also attached two pictures showing the dotted path line, 1 with even spaced dots at the start / End and another showing the problem I want to resolve, with not evenly spaced dots at the start / end.The only difference between the two is the point values.

When executing a click event on a button is there a way to know if a user has clicked or if code has executed it by a performClick in the sub that handles the click event. Maybe a change in the sender?
