asp.net loop checkboxes in gridview with DocumentFormat.OpenXml.Wordprocessing

it is ok to run this code to loop checked rows

dim abc as checkbox = row.cells(1).findcontrol("Cb")

 

but once add import DocumentFormat.OpenXml.Wordprocessing

findcontrol failed

function findcontrol is changed to UI.findcontrol

 

how can i fix it?  thank you very much

    It looks like you're trying to find a System.Web.UI.WebControls.CheckBox within a cell, but importing the DocumentFormat.OpenXml.Wordprocessing namespace makes the CheckBox class ambiguous (there is a CheckBox class in both System.Web.UI.WebControls and DocumentFormat.OpenXml.Wordprocessing).

     

    To get the checkbox from the cell, try using the fully qualifyed namespace. Also, I'd recommend a ctype and a null/nothing check:

     

    dim abc as System.Web.UI.WebControls.CheckBox = CType(row.cells(1).findcontrol("Cb"), System.Web.UI.WebControls.CheckBox)
If abc IsNot Nothing Then
    'do something here...
End If
