Binding TextBox in EVENT

[Garrett1226]

I have a Master/Detail WebForm Application that passes joined multi-table
data through multiple Datagrid levels.

When the user selects a Pushbutton to launch the next event that will bind
the next tier of Datagrids, how do I take that information that is populated
from my SELECT statement and fill a textbox control outside the datagrid?

I am assuming that I would place this information in the Sub that binds the
last data block of information? Here is that level:
Sub BindFinancialsGrid(ByVal param As SqlParameter)
Dim strSQL As String = _
"SELECT * FROM Financials WHERE Financials.FinancialsID = @financialsID"

FinPanel.Visible = True

With dgFinancials
.DataKeyField = "FinancialsID"
.DataSource = CreateDataSet(strSQL, param)
.DataBind()
.Visible = True
End With
End Sub

I figured that I could place all my textbox controls in a Panel and set the
visibility for when it should be loaded..... The correct information gets
binded to the DataGrid, How do I get the passed "cAssets" field to populate
the txtCAssets.Text control?

Thanks
