Checking if selected field contain value
I am selecting some contetnt from database and than display it into database. Something like that:
OleDbConnection objConn = new OleDbConnection(ConfigurationSettings.AppSettings["DSN"]);
OleDbCommand objCmd;
OleDbDataReader objRdr;
objCmd = new OleDbCommand("SELECT * FROM test'", objConn);
objRdr = objCmd.ExecuteReader();
dg.DataSource = objRdr;
dg.DataBind();
objRdr.Close();
Now I want to check if value of cell is something than display predefinited value in data grid. Sometingh like that:
if (objRdr["Name"] == "Joe"){
objRdr["Name"] = "Welcome Joe";
}
else
{
display value from database
}
(I know this is wrong, but I need something like that)
Tnx

How are you declaring the datagrid - specifically the AutoGenerateColumns property. If this property is set to false and you are using templates then, below is one solution.
<asp:Label runat="server" text='<%# CheckName(DataBinder.Eval(Container.DataItem, "Name")) %>' />
In the code-behind
public function CheckName(byval name string) as string
if name.toLower() = "joe" then
return "welcome joe"
else
return name
end if
end function

Here is my code:
<asp:TemplateColumn HeaderText="Units On Order">
<HeaderStyle horizontalalign="Center"></HeaderStyle>
<ItemStyle horizontalalign="Center"></ItemStyle>
<ItemTemplate><%# Check(DataBinder.Eval(Container.DataItem, "Test")) %></ItemTemplate>
</asp:TemplateColumn>
protected string Check(object Test)
{
if(Test.intValue() == 0)
return "Out Of Stock";
else
return Test.toString();
}
I get error: 'object' does not contain a definition for 'intValue'
What am I doing wrong??

Its because the intValue property does not exist. Change the function to this:
protected string Check(object Test)
{
if(Convert.ToInt32(Test) == 0)
return "Out Of Stock";
else
return Test.toString();
}
