I have DataGridView and I have a Add New Row Button and a Delete Row Button. What is the code to add a new row in the datagridview? Also the code to delete a row from the datagridview?
Note: I do not want to enable the AllowUserToAddRows and AllowUserToDeleteRows properties of the datagridview because I want to do it programatically.
I have a datagrid being filled by the data adapater connected to my database.I have a delete button on the form, i cant figure out how to delete the selected row on the datagrid when the delete button is clicked.
View 1 RepliesUsing 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?

I am having difficulty on the below code in understanding what is missing for the program to accomplish the below:Highlighted in red are the codes for Amend and Delete buttons:
1. The amend button was created to amend names, price and qty, with the code below it does amend the RentalRate(price) and intNoof Bike (Qty) however it does not change the Bike Name,
2. Delete Button code is as follows, when this is done i get an error "Index was outside the bounds of the array." at following bold red line

I have ModalPopupExtenders that show associations that are NOT tied to a specific product. The associations that ARE tied to the product are shown in a tabcontainer with delete imagebuttons next to them. When I was testing earlier I noticed that the associations that I delete from the tabcontainer don't show up in the modal unless I click on the refresh button in my browser. Is there some code I could use that would make it so that when I click on the delete button, it will automatically refresh my Modal so that I won't have that extra step? [code]
View 1 RepliesI'm trying to code the delete button in my binding navigator and I keep running into errors. This is what I have:Dim msg As String = "Are you sure you want to delete the current record? " If MessageBox.Show(msg, "Confirm Delete", _ MessageBoxButtons.YesNo) = DialogResult.Yes Then _CustomersBindingSource.Remove(DataGridView1.CurrentRow)
End If
Me.TableAdapterManager.UpdateAll(Me.DatabaseDataSet1)
Even when I change it to _CustomersBindingSource.CancelEdit and I debug it, the Delete button in the binding navigator looks like it set to enabled = false, but in the properites it's set to true.Even if I add enabled = true at the top
I have a main form (Form 1) with a menu strip and navigation bar. I use the main form to launch other forms (Form 2) as children of the main form.
All of the children forms contain SQL data sets /grids. I would like (if possible) to use the save button on the main form, to save data changes of the children form to the SQL database.
well, i am working on a project using tables by simply dragging and dropping them on a form.
from a single data set, i dragged 9 tables into 9 forms.. the fill method of tableadapter works whenever the form loads
now my problem here is, there's a problem with my binding navigator that the save and delete buttons aren't working..
this is actually my alternative method. since this morning.. i couldn't make my binding navigator work for my tables (i was surprised to see that there's only one working binding navigator from a single dataset, and because of that, i thought i could just use it to work for my 9 tables instead). still it doesn't work.. and i thought of using different forms for different tables so i could get the binding navigators work perfectly..
and yet, it doesn't make any change at all. still there is problems
is there any way to make this work?
how about adding codes into the delete button event in the binding navigator?
The code below shows adding three text boxes using a button, I'm thinking when there's excess of text boxes that has been added, how can I delete the excess using another button.[code]...

I have a block of code below that allows the user to create new buttons at runtime at the click of the right button at runtime.But i am wondering how to detect the selected button on the main form and then the user can delete the selected button at runtime.
The other thing the user can do is also to drag the button around the win form when in runtime. Cause i'm new in VB and i am exploring this part. the code that i have is here and it is created by one of the member in msdn.

I am currently working on a Web browser and I want to make a button to delete the browsing history. I found the file URLHIST.TLB but I cant Register it.
View 2 RepliesMay i ask you based on your codes last time to create a button, is this how i modify to delete off the button after i clicked on it? So that means to say i click on this button at location 15,41 then only this button will be deleted. the below is my code to delete the button but it is not consistent as sometimes it can delete more than one button when i click on one button.
Dim dr As DialogResult = MessageBox.Show("Are you sure?", "Check", MessageBoxButtons.YesNo)
If dr = Windows.Forms.DialogResult.Yes Then
PictureBox1.Controls.Remove(BTN)
