Question

I am working on a project where I am creating a dynamic table.Now depending upon my condition I am adding link button to table cells,but the click event of my link button is not working.I am not getting why its not working,neither its showing any error. Following is my code

public void makeCalendar()
{
    tblcalendar.Rows.Clear();
    //for current month
    DateTime startingdate = StartDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    DateTime enddate = EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    string startingday = startingdate.DayOfWeek.ToString();
    int startingdayno = Convert.ToInt32(startingdate.DayOfWeek);
    string endday = enddate.DayOfWeek.ToString();//like saturday is 6,stating is from monday with 1 and ending is sunday with 7
    int enddayno = Convert.ToInt32(enddate.DayOfWeek);
    //for prevoius month
    DateTime enddateprevious = (EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno)));
    //for next month
    DateTime startingdatenext = StartDateOfMonth(DateTime.Now.AddMonths(1));
    DateTime dtstart=startingdate.AddDays(-(startingdayno+1));
    //sMonthName = "January";
    //int iMonthNo = Convert.ToDateTime("01-" + sMonthName + "-2011").Month; 
    for (int i = 0; i <7;i++)
    {
        TableRow tr = new TableRow();
        for (int j = 0; j < 7;j++ )
        {
            TableCell tc = new TableCell();
            clickablecell ctCell = new clickablecell();
            //tc.ID = idtc.ToString();
            idtc++;
            if(i==0)
            {
                tr.CssClass = "firstrow";
                tc.CssClass = "firstrowcell";
                if (j == 0)
                    tc.Text = "Sun";
                else if (j == 1)
                    tc.Text = "Mon";
                else if (j == 2)
                    tc.Text = "Tue";
                else if (j == 3)
                    tc.Text = "Wed";
                else if (j == 4)
                    tc.Text = "Thu";
                else if (j == 5)
                    tc.Text = "Fri";
                else if (j == 6)
                    tc.Text = "Sat";
                tr.Cells.Add(tc);
            }
            else{
                tc.CssClass = "othercells";
                dtstart=dtstart.AddDays(1);                   
                //if date is single digit like 1,2
                if (dtstart.ToString("dd").Substring(0, (dtstart.ToString("dd").Length)-1) == "0")
                    ctCell.Text = (dtstart.ToString("dd").Substring(1));
                else
                    ctCell.Text = (dtstart.ToString("dd"));
                ctCell.Attributes.Add("onmouseover", "defColor=this.style.backgroundColor;  this.style.backgroundColor='LightGray';");
                ctCell.Attributes.Add("onmouseout", "this.style.backgroundColor=defColor;");
                //ctCell.ID = k.ToString();
                k++;
                ctCell.Click += new clickablecell.ClickEventHandler(textcell_Click);
                //check for events in this date
                DataTable dtevents = checkEvents(dtstart.ToString("dd-MM-yyyy"));
                if (dtevents.Rows.Count != 0)
                {
                    LinkButton lnkevent = new LinkButton();
                    //lnkevent.ClientIDMode ="Static";
                    lnkevent.ID = (i+j).ToString();
                    if (dtevents.Rows.Count == 1)
                    {
                        if (dtevents.Rows[0]["eventtype"].ToString() == "Holiday")
                        {
                            lnkevent.Text = dtevents.Rows[0]["eventtype"].ToString();
                            lnkevent.CssClass = "tcholidaytext";
                            ctCell.CssClass = "tcholidaytext";
                        }
                        else if (dtevents.Rows[0]["eventtype"].ToString() == "Event")
                        {
                            lnkevent.Text = dtevents.Rows[0]["eventtype"].ToString();
                            lnkevent.CssClass = "tceventtext";
                            ctCell.CssClass = "tceventtext";
                        }
                        else
                        {
                            lnkevent.Text = dtevents.Rows[0]["eventtype"].ToString();
                            lnkevent.CssClass = "tcimpdaytext";
                            ctCell.CssClass = "tcimpdaytext";
                        }
                    }
                    else
                    {
                        ctCell.CssClass = "tcmixtext";
                    }
                    //lnkevent.Attributes.Add("onClick", "test();");
                    //lnkevent.Click += lnkevent_OnClick;
                    lnkevent.Click += new EventHandler(lnkevent_OnClick);
                    ctCell.Controls.Add(lnkevent);
                }  
                tr.Cells.Add(ctCell);
            }
            tblcalendar.Rows.Add(tr);
        }
    }
}
 public void lnkevent_OnClick(object sender,EventArgs e)
{
    lblmonthname.Text = "hellooo";
    txttitle.Text = "";
}

I think the last link button must be working properly. Can u please check? — Palak.Maheria, Apr 24 '14 at 06:38
Have you tried using `lnkevent.Click += new RoutedEventHandler(lnkevent_OnClick);`? — Dumisani, Apr 24 '14 at 06:52
No i haven't used what it will do if I will use it,I haven;t used this event handler before,can you please elaborate a little — rupinder18, Apr 24 '14 at 06:53
It simply adds an event handler for your control. I forgot to mention that you'll need to replace `EventArgs e` with `RoutedEventAgrs e` in your method definition — Dumisani, Apr 24 '14 at 06:59
when I changed the event handler as you suggested,its showing error type or namespace missing — rupinder18, Apr 24 '14 at 07:08
Add reference to `Presentation.Core` then import `System.Windows` — Dumisani, Apr 24 '14 at 07:18

i suggest that you replace all this if-then-else conditions with case-switch... your code will be more readable and easier to debug... — onedevteam.com, Apr 24 '14 at 08:46

Sounds like you are adding a button, but not binding an event listener to it. I don't know much about how asp.net does event binding, but it sounds like that could be your problem.

Maybe this link can help?
