Question

So I have an <asp:Gridview> and in my C# file, I am setting the datasource to some database table, and doing .DataBind().

However, I want to hide a column in the table based on a Boolean variable.

Something like this:

gridview.Columns['Field5'].Visible = false;

Or perhaps:

int c = gridview.Rows.Count();
for(int i = 0; i < c; i++){
  gridview.Rows['Field5'].Remove();
}

Perhaps I cannot make it invisible, but I’m sure I can at least loop through and remove all rows related to the column “field5”. I don’t know how to go about doing this.

Does anyone perhaps have a proper link to using the GridView Class and how all the methods are suppose to be used because it’s not clear, perhaps not written by microsoft?

Sorry if this is simplistic, the internet seems to lack a lot of C# documentation (or maybe it’s just cluttered with too much useless ASP.net information).

Answer 1

In your case you should loop through gridview and set cells you want to hide Visible=false

        foreach (GridViewRow gvr in gv.Rows)
        {
            //here specify cell you want to hide  
            //also you may put any conditions
            gvr.Cells[0].Visible = false; // Hide cell
        }

To hide column you should go like that:

        //here specify column you want to hide  
        grv.Columns[0].Visible = false; // Hide column
