[Dr_Evil]

Yes but he has some work to do himself as well don't forget!!

 

[jackybaby]

i no! but ill let him tell me this not you thankyou very much

 

[jackybaby]

dont suppose you have a idea what it means

 

[Dr_Evil]

That particular method is declared to return void (thus nothing) and inside the method it's returning something, hence the compiler is giving you this warning... (I think, hard to say when I can't see the source-code)

 

[jackybaby]

fancy having a look

 

[Dr_Evil]

You want to learn or you just want someone to tell you how to fix the problem?

(Show me the Code!)

 

[jackybaby]

The problem is the following:

Your method 'GridView1_OnRowCreated' is declared as a method that has no return value (void), yet inside the method implementation you are trying to return a Dataset as the method return value, which is inconsistent with the method definition.

void GridView1_OnRowCreated(object sender, GridViewRowEventArgs e)
{
string connectionString = "ConnectionStrings:ConnectionString";
System.Data.SqlClient.SqlConnection sqlconnection = new System.Data.SqlClient.SqlConnection(connectionStri ng);

System.Data.SqlClient.SqlDataAdapter ad = new System.Data.SqlClient.SqlDataAdapter("SELECT * FROM [posters]", sqlconnection);
DataSet ds = new DataSet();
ad.Fill(ds);
return ds;

DataRow dr = ds.Tables[0].Rows[0];

Label blah = (Label)GridView1.FooterRow.FindControl("Label7");

blah.Text = dr["Units"].ToString();


}

If you want the method to return a dataset, then you must change the 'void' before the method name into 'DataSet'.

 

[jackybaby]

change it to ............?

 

[Dr_Evil]

first try commenting out the line: return ds; (by putting // in front of it) now the method is not supposed to return anything, and doesn't.

ive done that before abd it returns the error i had right from the begginning

that's a complete different error. I thought Stelly sorted that out for you?

 

[Stelly]

you dont need Text='<%# Eval("Units") %>'

Stelly

 

[Dr_Evil]

you dont need Text='<%# Eval("Units") %>'

That would irradicate the generics component of the Gridview class wouldn't it?

 

[jackybaby]

yer then i goes onto the next label eval etc.....
