Asp.Net Repeater ItemCommand dataitem is always null

Question

In repeater rpt_ItemCommand Event the e.Item.DataItem is always null.

Here is the code behind:

protected void rpt_ItemCommand(Object sender, RepeaterCommandEventArgs e)
{
    DataRowView drv = (DataRowView)e.Item.DataItem // here the DataItem is Null.
}

Suggest me any solutions.

Answer 1

除了ItemDataBound之外，DataItem属性始终为null ...它是由Microsoft设计的。

Answer 2

Think of using CommandArgument.

<asp:LinkButton ToolTip="Delete" CommandArgument='<%#Eval("Id") %>' ....

and use it in ItemCommand Event as

int id = Convert.ToInt32(e.CommandArgument);
