.net - Use DataGridView To Populate Text Boxes On The Form .NET 2010?
Aug 18, 2011
I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

I have an Access Database that contains two tables. I would like to populate 10 text boxes on my form with the data from the tables. For example: Table1 has a list of names 1 thru 5 and I would like to have 5 text boxes on my form when the form is loaded to populate those names. I know how to populate a combo box with the information, but not sure how to do it into individual text box
Current Code:
'create connection and command string
Dim conStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data

My screen tends to seize for a few seconds while the list boxes are populated.I moved the call to the List Populate procedure to the form's shown event.This improved the performance slightly but not enough.Is there a method whereby I can ensure the form is fully loaded and displayed before the lists are populated?

This task is a little out of my reach so i dont even really know where to start...I want a user to click the command field "select" in my gridview. I then want them to be redirected ( response.redirect()) to an input form that will have its various asp.net text boxes filled with data from that selected item. I also need the ability to do this logical process:
IF the form is loaded from user
selecting item in gridview THEN
''Populate controls with data from selected gridview item Else Load

In VB10/win forms project, when I change the forms font size the form and all the controls on the form get larger or smaller, OK great! The problem is the combo boxes then appear with their text highlighted. Is this a bug or am I doing something wrong, simple example..

I am building a program where for part of it the user can enter a parameter which will then query a database and populate a DataTable with the results if the number of results is greater than 1 it will call a "lookup" form to popuate a DataGridView with the DataTable, from this the user can select a row and the result is passed back to the main form or if the result is not there the "lookup" can be closed.
This works fine the first time the parameter is used to query and opens the "lookup" form and populates the DGV, but if the user returns the the main program after using the lookup form and enters a new parameter and the lookup form opens again the DataGridView is not created and populated. But i am 99% sure the DateTable is being populated as if the row count is 1 it will automatically return the single value and this is happening even after the lookup form has been used.
So it is just when the Lookup form is being used a second time the DataGridView is not being popuated or the DataTable is not being passed.

Is there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.

I am wondering is there an easy way to fill up text boxes. Lets say, i have a form with 11 text boxes. User puts a decimal number in one text box, hits button and that decimal number becomes converted to binary and i need to fill up all 10 other textboxes with elements of that binary code. My code looks like that:
Dim a As Integer
Dim s As String
Dim aa() As String

I need help getting the sum of a bunch of text boxes into another text box without using a button. Ive tried using TxtTotal = Val(txt1) + Val(txt2)... in the Total1_TextChanged but nothing happens. Someone once said I should use databinding but I cant see how that would work when Im using user input as the data to be Totaled. Also I dont know a whole lot about vb as I am just learning, and databinding
ps the values Im adding are in currency format. So I guess i would need to convert them back to add them, but im not sure.

The form has First Name, Last Name, Course and Email text box fields. First/Last Name must have no spaces, Course must consist of a three letters and two numbers in that order and nothing else(I want to avoid the use of masked text box), and Email must have the "@" sign and a dot. How would one make it so after clicking, say, Submit button and if there was a violation of any of the above rules then message box should pop up and tell the user which fields contain incorrect information.
Private Sub buttonAddNewStudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonAddNewStudent.Click
