gridview的删除，修改，数据绑定处理
行绑定数据后的处理：
protected void gdvQuery_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (this.gdvQuery.EditIndex == -1)
{
string confirmMeg = ManagerBusiness.GetMessageCodeManager.GetMessageByCode("007");
LinkButton lbtnDelete = (LinkButton)e.Row.FindControl("lbtnDelete");
lbtnDelete.Attributes.Add("onclick", "return confirm('" + confirmMeg + "')");
Label lblItemID = (Label)(e.Row.FindControl("lblItemTypeTemp"));
switch (lblItemID.Text.Trim())
{
case "1":
lblItemID.Text = "APPS";
break;
case "2":
lblItemID.Text = "GAMES";
break;
case "3":
lblItemID.Text = "APPS-GAMES";
break;
}
}
else
{
if (e.Row.RowIndex == this.gdvQuery.EditIndex)
{
Label lblItemIDEdit = (Label)(e.Row.FindControl("lblItemTypeEdit"));
DropDownList ddlItemType = (DropDownList)(e.Row.FindControl("ddlItemType"));
ddlItemType.SelectedValue = lblItemIDEdit.Text.Trim();
}
else

break;

break;

break;
}
}
}
}
}
catch (Exception ex)

throw;
}
}

删除
protected void gdvPartPartList_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
try
