I have an web infragistics grid which gets populated from below lines of code.

infraGrid.ClearDataSource();
infraGrid.DataSource = objCdtSearchResultsOutput.ResultsList.Tables[0];
infraGrid.DataBind();

Whereas in other class I have a method with below signature

public void GridOperation(int i,WebDataGrid wdgBillingPackageList)
{
}

Now when I am trying to invoke above method with below code

Obj.GridOperation(1, this.infraGrid);

I am getting NullPointerException. Above method call happens in the page where Grid gets populated. How to get it done ? What is being missed ?

try to send datatable as parameter in store procedure – jose Feb 01 '17 at 11:32
what is Obj? where did you define and is it initialized? – kgzdev Feb 01 '17 at 11:33
@Abion47 This is related to Grid, I am getting exception in page where data is available – user1197114 Feb 01 '17 at 11:33
@IkramTurgunbaev Obj is Object of Class where `GridOperation` method is defined – user1197114 Feb 01 '17 at 11:34
May be Obj not initialized, can you show how did you declare Obj? – kgzdev Feb 01 '17 at 11:34
Are you sure you are calling `obj.GridOperation` within the correct area of the page lifecycle? Have you set a breakpoint there to check that both `Obj` and `this.infraGrid` have been assigned? – gmiley Feb 01 '17 at 11:35
@IkramTurgunbaev May be that is the reason, I had it like `GridSelectionOp obj = Null`. Now updated to `GridSelectionOp obj = GridSelectionOp ()` – user1197114 Feb 01 '17 at 11:38
Well, if you were setting `obj` to `null`, there is no "maybe" about it. – gmiley Feb 01 '17 at 11:39
@IkramTurgunbaev Its Gone ! Working as expected. Thanks – user1197114 Feb 01 '17 at 11:40
It doesn't matter what this is related to, because your problem is the NullReferenceException. – Abion47 Feb 01 '17 at 11:52
