Updating dataview when changing dataset

1 New Member
I have a datagridview bound to a dataview of a typed dataset. The binding is accomplished with a bindingsource object.

When I programatically modify one of the datarows in the datatable of the underlying dataset, I want the datagridview to reflect the changes in the datarow. However, I am not able to make this happen.

Which object should I refresh, dataset, dataview, or datagridview? And how is this done? My implementation is in VB2008, but I guess this is not important for the general question.

Any suggestions?

Thanks,

Jon

When you update your DataSet you're going to have update the DataSource of your DataView and rebind (DataBind). When you do this you're going to have to update your GridView's DataSource to your updated DataView...and of course rebind this as well.

The following code retrieves data into a dataset, and then creates a dataview with a filter. This dataview is then attached to a combobox. When the effective date changes, I would like to see the newly filtered data without having to create a new dataview each time. Is that possible? Also, do I need to attach the dataview to the combo box each time? if (AgencyCounties == null || sPropertyState.Text != prevPropertyState) {...

I have a window application. On one of the form, there is a listbox and a few combox. The lstSchItem has a dataview as a datasource. The comboxes are bind to its selected value but through the dataset table. Now when I change the selection in the lstSchItem the comboxes are staying the same and not reflecting the changes. I tried changing the binding to the dataview.table but the comboxes are still not changing to reflect the...

I have a form with a dataset and a datagrid. I created a dataview on this dataset. When the user modifies the datagrid, I look up this record in the dataview to make sure it is unique. Here is the confusion......... I thought that the DataView is the view from the dataset, but it seems that the dataview has the records that are in the datagrid, because everytime I search for a record that I know is NOT in the dataset, it finds it.

Basically I have a DataGrid that I'm binding to the results of a stored procedure call. The recordset is fairly small. Initially I'm creating a DataSet from the results and binding it. There's a DropDownList on my page that filters the records that are displayed in the grid. How I'm currently handling this is when I initially bind, I create a DataView from the table in the dataset. When the DropDownList changes selection, I get the...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.
