Looping Through Data Grid View And Inserting Values Into Database?

Apr 5, 2011

Currently I have a problem with updating my database with values in my Data Grid View.

On my form I have a "Populate" button and "Submit Details" button.

The "Populate" button fills my Data Grid with numerous lines of data.

On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.

For Each dgi As DataGridView In DataGridView1.Rows

Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text

Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text

Compare Values In Datagridview With Values In Database Before Inserting Into Database

Dec 15, 2010

I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.

I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

Getting Cell Values Into Variables In DataGridView Based On Grid Coordinates?

Mar 20, 2011

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...

Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....

Presently, that will only display the data in column 0, row 0 in those labels...

Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

Combo Box And A Property Grid In A Form?

Dec 15, 2011

I have a combo box and a property grid in a form. The combo box contains 2 items. If one item is selected, two properties are listed in the property grid. These properties should have a dropdown that contains a list of items. I have two string arrays that contain the values for these properties. Can I use one TypeConverter that inherits StringConverter for these lists to be displayed in two different properties? That is, with one TypeConverter class, can I populate both the lists? I will also have to do the same with the other items in the combo box.

Inserting Null Values Into Date Fields?

Apr 20, 2012

I have a FormView where I pull data from one table (MS Access), and then insert it (plus more data) into another table. I'm having issues with the dates.The first table has two date fields: date_submitted and date_updated. In some records, date_updated is blank. This causes me to get a data mismatch error when attempting to insert into the second table.It might be because I'm databinding the date_updated field from the first table into a HiddenField on the FormView. It then takes the value from the HiddenField and attempts to insert it into the second table:

Dim hfDateRequestUpdated As HiddenField = FormView1.FindControl("hfDateRequestUpdated")
myDateRequestUpdated = hfDateRequestUpdated.Value
'... It then attempts to insert myDateRequestUpdated into the database.
