View 1 RepliesVS 2005 Data Grid View Oddity
May 28, 2009I'm working with a DataGridView. The DataSource for the DataGridView is set to a DataTable that I've populated with the results of a SQL query.
Then, I add an extra column to the DataGridView, a DataGridViewCheckBoxColumn. This allows the user to select a number of records in the datatable in order to save out selected files, represented by the rows of the datatable/DataGridView.
I have buttons that will programmatically check/uncheck all of these CheckBoxes, as there are frequently several hundred rows in the DataGridView. The user can also check/uncheck any number manually.[CODE..]

VS 2005 Importing Data Not Working?
Mar 16, 2011I have a table in my database. I have an import routine which reads rows from and XML file. It first loops through my existing table to see if the row exists using a date and store code column as a unique id. It all works fine until this senario occurs.First file is read in and a new row is added for 01/03/2011, store code 100. The second file is read in which also has a row with 01/03/2011, store code 100. But when I loop through it does not find the row I just added so it adds it again.The only solution I can think of is to re-populate the local table everytime I add a new row but this will have a massive amount of over heads.If I add a row to an existing dataset surely if I loop through that dataset I should come across it.

.NET 2.0 .settings Not Working Properly?
Oct 18, 2011I don't even know where to begin describing this. I have a project, that uses settings, for some paths, settings that I retrieve with the My.Settings. function.In my laptop, when I change the .exe.config file, the settings are updated accordingly, but when I try that on the production server, it just shows the default value used while compiling.
I tried changing the solution configurations to debug and other custom configs with no effect.Tried to use the same folder copied and pasted without version control, still the same result.Tried a co-workers laptop, by using the last svn revision, it works there too. But on neither of the servers works.

Checkbox In Datagridview Not Working Properly?
Aug 16, 2010I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.
