View 2 RepliesHow would I delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If I dont delete the successful rows then I will have multiple inserts of the same dataRow and we dont want that! And if I don't move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic I am trying to perform at the bottom of my code, right after I insert into the database.
Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.
The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.
Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.

I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?
I can't seem to figure out how to update a single column for every row in my database...
