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.
i can make a button appear in the DataGridView, but i want to be able to load a form when i click on the button, how do i do that? I cant double click on the button to load the code because it will only appear when i run the application
The following code is to display the button objButtonColumn = New DataGridViewButtonColumn objButtonColumn.HeaderText = "Edit" objButtonColumn.Name = "EditColumn"
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.
So I still working on a program that shows this. This is the code that I use two show the SA and PLATINUM text because on the file they are not the only characters on the line, like this:
set username=sa set password=platinum code to search only those two words.
I've got a custom button control that I made and it works great. I love it and it's perfect, but I do miss the PerformClick() function on the default Windows buttons...How would I make one for my button?
I am trying to detect when the user selects a checkbox on the new line of a datagridview
I am using the following code but it doesn't detect the new line has been selected. When running debug IsNewRow shows as FALSE
Private Sub DataGridView1_CellContentClick(sender As System.Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
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
In VB.NET, windows form has the Checkbox as first control and when form loads focus has to be set to the checkbox and display the dotted rectangle over the checkbox as shown below in screen shot.
I am developing a program where i will download and save an xml file from a url as abc.xml. I open the abc.xml in a datagridview with a dataset without problem.I am confused how can i read raw per raw the datagridview and assign the data in a database table? i am using vb 2008 + msde2005 express.I show the whole content of the xml file in the datagridview with the following [code]I dont know how to create a loop where i can read the datagridview line by line save data in variables (ex.strings) and save it in a databese table?
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 want to ask how to use the performclick() function is this function applicable only to windows forms and not website? if its applicable to website can you show me how to use it.
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.
I have a text file which contains large amount (around 44,948 rows/lines & 9 columns) of delimited text data in a text file which I want to populate onto a DataGridView table. I have written the below code, but the application gets hung for the rest of the time & so I have to stop debugging the program.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim x As New IO.StreamReader(fileLocationTxt.Text)
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?
I am populating a listbox with a large list. The user then has the option of choosing multiple items from this list. I then want to perfrom a few actions on only the selected items.I cant figure out how to only perform the actions on only the highlighted selections.
'I have tried all combinations of
For each Listbx.SelectedItems.ToString in ListBx.Items.ToString For each Listbx.SelectedItem in Listbx.Items 'etc, etc ''Performing actions here but it is still doing it with all entries Next
