GridView常用代码
1. GridView1_RowDataBound
protected void GridView1_RowDataBound(object sender,GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton l = (LinkButton)e.Row.FindControl("LinkButton1");
l.Attributes.Add("onclick", "javascript:return " + "confirm('Are you sure you want to delete this record " + DataBinder.Eval(e.Row.DataItem, "CategoryID") + "')");
}
}
2. GridView1_RowCommand
protected void GridView1_RowCommand(object sender,GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
// get the categoryID of the clicked row
int categoryID = Convert.ToInt32(e.CommandArgument); // Delete the record
DeleteRecordByID(categoryID); // Implement this on your own :)
}
}
3. GridView1_RowDeleting
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int categoryID = (int) GridView1.DataKeys[e.RowIndex].Value;
DeleteRecordByID(categoryID);
}
4. CommandArgument, CommandName
<asp:TemplateField HeaderText="Select">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" CommandArgument='<%# Eval("CategoryID") %>' CommandName="Delete" runat="server">Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
(在GridView1_RowCommand里，有他们的用法）
