how to active & deactive in GridView

Question

Dear All,

I have table with the following fields

Item ID, Item Name, Price, Active.

Here Active column contains only 0 or 1 ie.
1-Available
0-not available

Here I binded this table with Gridview with Active/Deactive link button in it.
with addition of it Edit & Delete also

Now my requirement is I need to show available items & unavailable items also in Gridview but unavailable items will be with some light color.. when i click Active/Deactive button it will be in unavailable format & Edit & Delete buttons will be in Disable mode, When user clicks again Active/Deactive button which will be in normal view & Edit & Delete buttons will be Enabled.

How can i do this?

Hi,

For example,

<asp:gridview id="ContactsGridView" 

              datasourceid="ContactsSource"

              allowpaging="true" 

              autogeneratecolumns="false"

              onrowcommand="ContactsGridView_RowCommand"

              runat="server">

              <columns>

                <asp:buttonfield buttontype="Link" 

                  commandname="Add" 

                  text="Add"/>

                <asp:boundfield datafield="ContactID" 

                  headertext="Contact ID"/>

                <asp:boundfield datafield="FirstName" 

                  headertext="First Name"/> 

                <asp:boundfield datafield="LastName" 

                  headertext="Last Name"/>

              </columns>

            </asp:gridview>

the server side event is,

void ContactsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)

  {

    // If multiple buttons are used in a GridView control, use the

    // CommandName property to determine which button was clicked.

    if(e.CommandName=="Add")

    {

     LinkButton lbtnActive = (LinkButton) e.FindControl("lbtnActive");

        lbtnActive.Enabled = false;

       //If you want to set the color then

e.Row.BackColor;

        e.Row.ForeColor;

    }

  }

Hi, Its showing error message that does not contain definition for FindControl() Are you missing a using directive or assembly reference
