Error: Both DataSource and DataSourceID are defined on 'GridView2'. Remove one definition. ?!

Question

when I write this query (using LINQ):

        Dim hw22 = From hw In db.HWs _
                   Select hw

then:

        GridView2.DataSource = hw22
        GridView2.DataBind()

this error occurs: http://www.rofof.com/img2/6hscmu7.gif

How can I solve this?

Answer 1

you probably have the DataSourceId defined in markup code

Answer 2

remove DataourceID from html source of gridViewdio

Open aspx page in visual studio

click on source , this will show you html source of the page

look for this line of code

inside this tag there will be a line like DataSourceID = something ,,,,,remove this

Answer 3

Is it possible to define the datasource ID in the gridview and dynamically bind it to another datasource during one condition????

Answer 4

If you don't want to remove it in markup then do this:

GridView2.DataSourceID = ""
GridView2.DataSource = hw22
GridView2.DataBind()
