also, u can aways create a admin.aspx page and set the view to insert/edit or whatever u want. the same way, u can set the view for normal users to read only.

this way u need only to protect the page.

Hi, Im just trying this and have the following code, which I have used from the

protected void Delete_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (Roles.IsUserInRole(User.Identity.Name, "Administrator"))
            {
                ImageButton btnDel = e.Row.Cells[6].Controls[0] as ImageButton;
                btnDel.visible = true;
            }
            else
            {
                ImageButton btnDel = e.Row.Cells[6].Controls[0] as ImageButton;
                btnDel.Visible = false;
            }
        }
    }

above example.

The problem is the following message appears:

'System.Web.UI.WebControls.ImageButton' does not contain a definition for 'visible'

Any idea? Cheers, Mark

you can also use the load event of a formview, and put the condition of hiding and showing the edit/insert/delete button.

well let us assume you have a usertype session that will determine if we will view the edit/insert/delete button.

    protected void example_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

if(Session["usertype"] == "admin"){
Button btnsample= (Button)e.Row.FindControl("insertbutton");

btnsample.visible = true;
}

else

{

Button btnsample= (Button)e.Row.FindControl("insertbutton");

btnsample.visible = false;

            }
        }
    }

This is a very good example of how NOT to ask a question.

Do you have any knowledge of C# or VB?

on rowcreated, Use e.Row.Cells( index of required cell, in this case probably 0 ).Visible = False

likewise, change the index for any other columns which you want to hide. I would suggest writing a hidecolumns function.

What about the FormView controls. How do I allow administrators to see the edit/insert/delete functions and hide those controls from any other user ?

Also, going back to your response, what exactly am I to type under the rowdatabound gridView control ? Can you provide me with a sample ?

Thanks.

yes. you can access the controls inside a gridview and formview, then their are events in the gridview called rowdatabound which you can use to show or hide certain controls inside that row.

I am building an application that need to be flexible enough to hide certain pieces of information withing a page based on who the user is.

More specifically, I have a gridview/formview which needs to allow certain users to edit/insert/delete information while at the same time would limit other users to view information.

Is this possible and how will I go about doing this ?

Thanks in advance.
