你到底是想在后台获取Repeater数据源的值还是获取Repeater前台输入的值?

DataRow dr = null;
for(int i=0;i<5;i++){

dt.Rows.Add(dr);
}
this.Repeater1.DataSource= dt;
this.Repeater1.DataBind();
}
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if(e.Item.ItemType==ListItemType.Item){
string id = ((Label)e.Item.FindControl("lblId")).Text;
ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('" + id + "')", true);
}
}
protected void lbtID_Click(object sender, EventArgs e)
{
LinkButton lbtId = (LinkButton)sender;
string id = lbtId.CommandArgument.ToString();
ScriptManager.RegisterStartupScript(this,this.GetType(),"","alert('"+id+"')",true);
}
}
不用Eval()好像不行,repeater是一个需要编辑的控件不像GridView有datakeyNames属性可以用
