Updating database using datagridview c
Additionally, extra columns in the source dataset are added to the target dataset.
Merging datasets is useful when you have a local dataset and you get a second dataset from another application.
If you aren't using data binding, and are saving changes for related tables, you have to manually instantiate a variable of the auto-generated Table Adapter Manager class, and then call its Udpate All method.
If you aren't using data-bound controls, then you have to manually call the Update method of the same Table Adapter (or data adapter) that you used to populate the dataset.
However, you can also use different adapters, for example, to move data from one data source to another or to update multiple data sources.
After you complete an update, you can re-enable constraint checking, which also re-enables update events and raises them.
For more information about suspending events, see Turn off constraints while filling a dataset.
Because datasets maintain multiple versions of records, it's important to keep in mind that more than one version of the records is being merged.
The following table shows how a record in two datasets is merged: dataset.
This means that if you try to update the original data source with the target dataset, it might not be able to find the original row to update.
You can prevent a concurrency violation by filling another dataset with the updated records from the data source and then performing a merge to prevent a concurrency violation.
I am really looking for any way to use a Data Grid View to update a SQL table.
If is going to stray much from my code, I would like detail and some explanation.
If you intend to update an underlying data source later, you must use the methods on the Data Table.Tags: Adult Dating, affair dating, sex dating
