This is very similar to these questions, but they didn't seem to help me (will explain why below):
- How to create an onClick eventHandler for a dynamically created button
- asp.net dynamically button with event handler
- asp:Button Click event not being fired
I'm creating a C# aspx page. That page grabs a bunch of data and then builds a table out of it. One of the columns in the table contains a button that gets dynamically created as it builds the data (since the button's action relies on the data in the table).
Default.aspx
<body>
<form id="form1" runat="server">
<div>
<asp:Table ID="tblData" runat="server"></asp:Table>
</div>
</form>
</body>
Defafult.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
Build_Table();
}
protected void Build_Table()
{
//create table header row and cells
TableHeaderRow hr_header = new TableHeaderRow();
TableHeaderCell hc_cell = new TableHeaderCell();
hc_cell.Text = "This column contains a button";
hr_header.Cells.Add(hc_cell);
tblData.Rows.Add(hr_header);
//create the cell to contain our button
TableRow row = new TableRow();
TableCell cell_with_button = new TableCell();
//create the button
Button btn1 = new Button();
btn1.Click += new EventHandler(this.btn1_Click);
//add button to cell, cell to row, and row to table
cell_with_button.Controls.Add(btn1);
row.Cells.Add(cell_with_button);
tblData.Rows.Add(row);
}
protected void btn1_Click(Object sender, EventArgs e)
{
//do amazing stuff
}
Here's where I'm tripping up. I understand that my EventHandler isn't being fired because it needs to be moved over to the Page_Load method. However, if I move the btn1 creation and EventHandler over to Page_Load, I can no longer access them in Build_Table!
All of the code examples I see either have btn1 statically added in the ASPX page, or have it dynamically created in Page_Load. What's the best way to do what I'm trying to accomplish?
