Question

I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.

I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc…. that correlate with DataEntryUC.

How do I reference a text box that is on DataEntryUC from NavSaveUC?

I have been working on the following code from NavSaveUC with no luck.

Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String
Dim tmpTxtControl as TextBox
Dim tmpDdlControl as DropDownList

Select Case MyControlType
    Case "TextBox"
        tmpTxtControl = CType(Page.FindControl(MyControlName, TextBox)
        MyStringValue = tmpTxtControl.Text                  
    Case "DropDownList"
        tmpDdlControl = CType(Page.FindControl(MyControlName, DropDownList)
        MyStringValue = tmpDdlControl.SelectedValue
End Select

Thanks!

Expose the textbox as a property of the user control and access it that way. This type of dependency is not a best practice though.
