Updating database with datagrid in
If you have thousands, then it might be an issue, but there is no way to maintain the same order of rows in the grid as in the table. If you are really ordered about having to rewrite the entire table, then here is an alternative.
What you can do is create a trigger before the Dyna Form with the grid like this to create a copy of the grid, with keys based on the ID field:$db Connection = 'workflow'; //set to ID of the DB Connection if using an external DB$table Name = 'PMT_YOUR_TABLE'; //set to table [email protected]=Original Grid By Id = array();foreach (@=your Grid as $row) for ($i = 1; $i The problem with this code is that it doesn't handle the situation if the user can delete rows in the grid.
The Io T world may be exciting, but there are serious technical challenges that need to be addressed, especially by developers. I have a datagrid that is pulling data from a SQL Server 2000 database. I need to have the datagrid update all the changes from all rows to my database by clicking on an update button.
In this handbook, learn how to meet the security, analytics, and testing requirements for Io T applications. The built-in edit function where you can only edit one row at a time does not help us. I read the answer you wrote asked on 21 July 2003 and it seems to help a little, but the answer is in C#.
I have been struggling with the below code trying to get it to work.
Thanks in advance,donelson07donelson07, First of all, the above code won't work if the user is allowed to delete rows in the grid, nor will it work if the user is adding rows or the value of the ID field is autogenerated by My SQL.
Is Valid) Dim ds As Data Set = CType(Session["data"], Data Set) Dim item As Data Grid Item //Iterate and apply changes to the dataset For Each item In Data Grid2.
Items Dim mytxt As Text Box = CType(Text Box, item.
Then add code to your trigger to delete those rows.
