user control

[Hrvoje Voda]

I'm using this code to check click event on usercontrol.
But I get an error:
User Control:(GridFi lter)
public delegate void FilterText(stri ng filterText);

public event FilterText textFilter;

private void buttonTrazi_Cli ck(object sender, EventArgs e)

{

if (textFilter != null)

textFilter(txtF ilter.Text);

}

Main form:

private void Main_Load(objec t sender, EventArgs e)

{

GridFilter.text Filter += new Utils.GridFilte r.FilterText(gr idFilter);

}

protected void gridFilter(stri ng filter)

{

string tree = treeKolekcija.S electedNode.Tex t;
switch (tree)

{

case "Akcioni":

DataRow[] afrows = db.dataSetKolek cija.Akcioni.Se lect("Naziv LIKE '" +
filter + "%'" );

DataTable newtable = new DataTable();

int c = 0;

foreach (object o in afrows[0].ItemArray)

{

newtable.Column s.Add(new DataColumn(stri ng.Format("col{ 0}", c++),
o.GetType()));

}

foreach (DataRow dr in afrows)

{

newtable.Rows.A dd(dr.ItemArray );

}

gridData.Grid.D ataSource = newtable;
break;

}

}

You haven't assigned the Button Click event handler to the handler method
you created.

I don't understand.
I have an event textFilter that I check in button_click event.

You created a Button click event Handler method, but you didn't assign it to
the Button's Click event. You need to do something like the following:

buttonTrazi.Cli ck += new EventHandler(bu ttonTrazi_Click );

I get an error on main form.

error : An object reference is required for the nonstatic field, method, or
property 'Utils.GridFilt er.textFilter'

"On main form" is not very useful information. Where specifically does
your error happen? What causes it to happen?

Not that you should at this point really need our help. It seems to me
that the error is pretty self-explanatory. Somewhere you are using
"Utils.GridFilt er.textFilter" and it requires an object reference even
though you are not providing one. You should be able to figure that one
out. If not, you really need to provide actual information that describes
the context of the error for us.

[Hrvoje Voda]

it worked fine on another control.
Now, I put it on a different control and it doesn't work.
