[Suny]

Hello everybody ... I have a gridview that display data from SQL table using the Configure data source with where clause to show data based on 2 Dropdown list


It works fine and the data already show based on the choices of the drop menu .... but I need to SHOW ALL Items on gridview when I select the SHOW ALL from the dropdown menu

Can anybody help me please???

Is your DropDownList configured to autopostback?
Do you have code that handles it's selected index changed event?

If so, have you tried setting the DataSource of the GridView to a source that has all of the records?

If so, did you call the DataBind method on the GridView after you set it's DataSource?

Thanks for your kindly reply and your attention

Yes my dropdownlist configured to autopostback

No I didn't generate any code (it's required to do it without any coding)

Yes I did , It's connected to the data source (table) that has all the data

Look I did it as follow:
1- My grideview -- add data source -- add new datasource.
2- choose the connectionstring
3- On the configure the Select data source I choose the all fields then click the Where button.
4- Choose the Data control = Dropdownlist 1 then choose the field and the same for dropdownlist 2

Now it works fine and it filter the data except It didn't return the ALL value
