user control

[Hrvoje Voda]

I'm using this code to check click event on usercontrol.
But I get an error:


User ControlGridFilter)
public delegate void FilterText(string filterText);

public event FilterText textFilter;



private void buttonTrazi_Click(object sender, EventArgs e)

{

if (textFilter != null)

textFilter(txtFilter.Text);

}

Main form:

private void Main_Load(object sender, EventArgs e)

{

GridFilter.textFilter += new Utils.GridFilter.FilterText(gridFilter);

}

protected void gridFilter(string filter)

{

string tree = treeKolekcija.SelectedNode.Text;


switch (tree)

{

case "Akcioni":

DataRow[] afrows = db.dataSetKolekcija.Akcioni.Select("Naziv LIKE '" +
filter + "%'" );

DataTable newtable = new DataTable();

int c = 0;

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

{

newtable.Columns.Add(new DataColumn(string.Format("col{0}", c++),
o.GetType()));

}

foreach (DataRow dr in afrows)

{

newtable.Rows.Add(dr.ItemArray);

}

gridData.Grid.DataSource = 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.Click += new EventHandler(buttonTrazi_Click);

I'm using this code to check click event on usercontrol.
But I get an error:

What error do you get? Where does the error happen?

 

[Hrvoje]

I get an error on main form.

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

I get an error on main form.

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

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