c# - Getting Error while read the data from table -

-

I am displaying all the data from the database table in Gridview. I have attached the database file to the app folder but when I am running the application, I am getting the error like

Login can not open the database requested in the 'Employee' login fails User 'HOME-47F64BE31D \ Administrator'

Here's my complete code:

aspx page: 

  & lt; ASP: Gridview id = "Gridview 1" runat = "server" Autogrentech column = "Fotal" & gt; & Lt; Columns & gt; & Lt; ASP: BoundfieldDefined = "Firstname" header text = "Firstname" /> & Lt; ASP: BoundfieldDefined = "Last name" header text = "last name" /> & Lt; ASP: BoundfieldDefined = "Hiredate" header text = "Hiredate" /> & Lt; / Column & gt; & Lt; / ASP: GridView & gt; & Lt; Asp: label id = "lblStatus" runat = "server" & gt; & Lt; / Asp: label & gt;

aspx.cs: 

  protected void Pej_lod (object sender, Iventaarjis e) {if (! IsPostBack) GetData (); } Private Zero GetData () {string str = ConfigurationManager.ConnectionStrings ["ConnectionString"]. ConnectionString; SqlDataAdapter da = New SqlDataAdapter ("GetEmp", str); Da.SelectCommand.CommandType = CommandType.StoredProcedure; Dataset ds = new dataset (); Da.Fill (DS); GridView1.DataSource = DS; GridView1.DataBind (); }

Please help me what is the error?

Your error actually looks like: database access error that HOME-47F64BE31D \ Administrator < / code> the user does not have access to your database, you have two options:

  • for the user to access their database you define through its SQL Management Studio that allow can do.
  • To notify a user with permission in your query string;

With a user with permission User ID = aaa; To add password = BBB , edit your configuration file, in the form of a side note, you will see the sa user in your application

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
