GridView event handler not working

compninja25

Hi all, I'm still fighting with getting multiple lines in a dynamic gridview. Searching around led me to think that if I can change the data during the rowcreated handler this just might work.

gv2.RowCreated += new GridViewRowEventHandler(gv2_RowCreated);
gv2.DataBind();

protected void gv2_RowCreated(object sender, GridViewRowEventArgs e)
{
for (int i = 0; i < 5; i++)
{
e.Row.Cells[i].Text.Replace(Environment.NewLine, "
");
}
}

Whenever I run the debugger, the new event handler line adds the handler, but never runs through the block of code. I'd imagine that during the DataBind, the rows are being created, so why isn't the system seeing this event?

From where you are executing this ? If you want to execute Event handler of a runtime created controls, you need to add this event handler before Page_Load()

Why are you not using RowDataBound event?I think it'll fulfill you requirement.

I tried that first but it gave me the same results.

Ah, maybe that's why! It's actually in the block of code that is being called from within the Page_Load().

No Brij, I Think, his problem is something different. He Needs add event handler before page_load.

Well, after moving it to the Page_PreLoad the event fires but apparently replacing the element.newline with the "
" didn't do the trick. Dang!

Hey Dude Adding a eventhandler with every row means he wants to execute some statements on every row addiotion.My answer was the same can be done using RowdataBound function with ease.

Here's the code:

{
    Generate\_Table();
}

    //Generate\_Table();

    DataRow dr1 = Table1.NewRow();
    for (int i = 0; i < 5; i++)
    {
        Table1.Columns.Add(DateTime.Today.AddDays(date).DayOfWeek.ToString() + " " + DateTime.Today.AddDays(date).ToShortDateString(), typeof(string));
        try{
            dr1\[i\] = content1\[DateTime.Today.AddDays(date).ToShortDateString()\];

             }
        date++;                     
    }

    date += 2;

Hey Guys, I got it working. It was actually a combination of both your responses. I did have to move everything to the Page_PreLoad() and also do a RowDataBound event handler instead of RowCreated. I also had to change the event handler to this after it dawned on me that I'm replacing but not specifying that's what I want to be in the text area!

e.Row.Cells[i].Text = e.Row.Cells[i].Text.Replace(Environment.NewLine, "
");

Thank's for taking the time to help me out!
