Where to put the delegate statement

Where to put the delegate statement

BenTam-3003 686

Dear All,

According to the webpage http://objectlistview.sourceforge.net/cs/recipes.html#how-can-i-put-a-button-into-a-cell, I can use a delegate statement to get the 'RowIndex' of the current row. I'd like to know where should I put the delegate statement?

can you elaborate, by where do i put are you reffering to the code behind view of your form. so by right clicking on the form and select code view you should be able to add the code in the main forms class.

I am also trying to understand your question around "where should I put the delegate?"

are you referring to where on the project you should put the code?

are you referring to the onbutton click event and where that should go?

You just add it after the creation/initialization of the ObjectListView

For example with an OLV named dataListView1, in Form1_Load :

            dataListView1.ButtonClick += delegate (object dlvsender, CellClickEventArgs ea)  
            {  
                System.Windows.Forms.MessageBox.Show(String.Format("Button clicked: ({0}, {1}, {2})", ea.RowIndex, ea.SubItem, ea.Model), "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);  
                dataListView1.RefreshObject(ea.Model);  
            };

Hi @Castorix31

Thank you for your reply. I follow your instructions and put the statements into 'StudentList_Form_Load'. However, there are 2 errors as shown below.

You must cast to a OLVColumn :

OLVColumn col = (OLVColumn)StudentList_dataListView.Columns[0]; col.IsButton = true;

and for CellClickEventArgs, you must add at beginning :

using BrightIdeasSoftware;
