I noticed that you are adding some controls in the GridBoundColumn OnItemDataBound
event handler. Note that those controls will not be saved in the ViewState
and after rebind they will be lost. If you want to add a controls in a grid column then I would recommend you to use a GridTemplateColumn
. You can find more information about this column type at the following help article
and the following help topic
describes how to access its controls.
