I'm creating a really simple app that connects to a SQL Server 2005 data sourceThere is a DataGridView component that binds to a single table. The data pulls up just fine, and I am able to add and edit records in the grid, however, it does not actually update the tables.

which is supposed to get all the data from my table and set it as the datasource of a DataGridView. You can see where I put in two msgbox's to view how many columns are in the DGV before and after the "update". The first count gives me 22, which is the correct number. After the .DataSource and .DataMember lines are ran, the count jumps to 41 and I have no clue why. All I want to do is clear a dataset, fill it with the new data and set it as the data source of a datagridview. It appears the info is being saved to the table correctly too.
How to update data in a table bound to a datagridview? Using Visual Basic 8.
View 1 RepliesI have a DataGridView bound to a data table. I have one column where I permit updates. After I fill the table (at form load), I make an update to this column Then I attempt to update the change back to the bound table. I get the error 'Update requires a valid Updatecommand when passed dataRow collection with modified rows'. I have seen some examples on-line to define, load, and update but since I have the generated datagridview with bindings, shouldn't the update method me a simple 1-liner? [Code]

View 3 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
Objective to clear the datagrid view after updating. This should happen when the user clicks the OK button when the update is confirmed. Below is what i have.I currently have
