Examples
The following example shows how to find the text box control for a specified column name. In example, the Dynamic Data page templates are copied to the \DynamicData\CustomPages\ProductDescriptions folder to provide a custom display for the ProductDescription table of the AdventureWorksLT database. The Insert.aspx file markup is changed to add an OnDataBound
event handler named DetailsView1_DataBound
, in which the FindDataSourceControl method is called to find a text box control.
