In the Visual Studio 2005 designer, I have a grid, a binding source, and a
data set which contains two data tables.
In the Designer, I make the settings below. If I set the DataMember for the
binding source to Table1, I see the data in Table 1. If I set the DataMember
for the binding source to Table2, I see the data in Table 2. This all works
great.
I need to be able to reassign the DataMember for the binding source at
run-time. If I assign it to the same table that's set in the designer, I see
data. If I assign the DataMember to the other table, I don't see any data in
the grid.
Has anybody successfully switched DataMember assignments for a Binding
Source at run-time? If so, is there something like refresh that I'm missing?
Thanks,
Randy
myGrid.DataSour ce = myBindingSource .
myBindingSource .DataSource = myDataSet
myBindingSource .DataMember = myDataSet.Table 1
**OR**
myBindingSource .DataMember = myDataSet.Table 2 1 8951
I'll answer my own question. I'm using a third-party grid, and I needed to
use the following rebind command to refresh the binding between the grid and
the binding source after updating the binding source:
myGrid.Rebind(t rue);
Now I can switch between the data in either table at runtime.
Gee, I wonder if I can mark my own response as helpful...<ggg>

Hi All,
I have two pagetabs. One pagetab is used to display a parent record and the
other is suppose to display 3 related child records from another table.
I can display the parent records just fine by using the bindingSource and a
tableAdapter to fill the dataset. I'm having a problem displaying the 3
related records on the other pagetab....

Hi misters,
I used the Data Sources window to drop a custom object onto the designer

When I open the Properties window on the BindingSource, I see DataSource
