我的Gridview是一种让我查看数据库表并在需要时执行编辑和更新的方法
数据实际上是由飞蛾,年和DaysPerMonth(可工作日数)组成的
所有字段都是Int
所以显示当前月份而不是我正在使用的给定月份的int值/格式 从数据库中以两种方式进行翻译 - 在gridview中显示为月份名称(字符串)
public static CultureInfo ILci = CultureInfo.CreateSpecificCulture("he-IL");
public static string GetMonthName(int mInt, int mYear=2012)
{
DateTime fullDate = new DateTime(mYear, mInt, 2);
string[] tempDayArray = fullDate.ToString("MMMM", ILci).Split(' ');
return ILci.DateTimeFormat.GetMonthName(mInt);
}
并通过“translator”/ formatter
返回数据库 public static int GetMonthAsInt(string mStr)
{
return DateTime.ParseExact(mStr, "MMMM", ILci).Month;
}
从开始 - 视图模式开始,所有阶段都可以 通过编辑 - 编辑模式 即使在更新模式下,
我可以用VS调试器查看 实际上“Good To Go”的SQL数据源更新命令的值 并在SQL server查询中执行它的命令 返回一个succcesfull结果。
因此问题仍然存在于更新结束时或更新后的DataBind(); 最后一行 我得到的错误/例外是:
输入字符串的格式不正确。
这是GV_DaysPerMonth_RowUpdating事件处理程序代码
protected void GV_DaysPerMonth_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
// by recived i ment what is taken by sql command from gridview
string recivedNameMonth=string.Empty;
int recivedYears = 0;
int recivedDprM = 0;
int RowNo = 0;
GridViewRow CurRow = GV_DaysPerMonth.Rows[e.RowIndex];
string[] formValues = new string[CurRow.Cells.Count-1];
bool note = ((TextBox)(CurRow.Cells[0].Controls[1])).Text != null;
if (note)
{
for (int i = 0; i < CurRow.Cells.Count-1; i++)
{
formValues[i] = ((TextBox)(CurRow.Cells[i].Controls[1])).Text;
}
//recivedNameMonth = ((TextBox)(CurRow.Cells[0].Controls[1])).Text;
}
RowNo = e.RowIndex + 1;
recivedNameMonth = formValues[0];
int Montint = RobCS.RDates.GetMonthAsInt(recivedNameMonth);
recivedYears = Convert.ToInt32(formValues[1]);
recivedDprM = Convert.ToInt32(formValues[2]);
dsWorkDayPerMonth.UpdateCommand = "UPDATE [tblWorkDaysPerMonth] SET [theMonth] = " + Montint+ ", [theYear] = "+recivedYears+",[WorkDaysPerMonth] = " + recivedDprM + " WHERE [recordID] = " + RowNo;
GV_DaysPerMonth.DataBind();
}
在
上使用它SqlDataSource
<asp:sqldatasource runat="server" id="dsWorkDayPerMonth"
ConnectionString="Data Source=(local);Initial Catalog=hental;Integrated Security=True"
ProviderName="System.Data.SqlClient"
SelectCommand="SELECT * FROM [tblWorkDaysPerMonth]"
UpdateCommand="UPDATE [tblWorkDaysPerMonth] SET [theMonth] = @theMonth, [theYear] = @theYear,
[WorkDaysPerMonth] = @WorkDaysPerMonth WHERE [recordID] = @recordID"
DeleteCommand="DELETE FROM [tblWorkDaysPerMonth] WHERE [recordID] = @recordID"
InsertCommand="INSERT INTO [tblWorkDaysPerMonth]">
<UpdateParameters>
<asp:Parameter Name="theMonth" Type="Int32" />
<asp:Parameter Name="theYear" Type="Int32" />
<asp:Parameter Name="WorkDaysPerMonth" Type="Int32" />
<asp:Parameter Name="recordID" Type="Int32" />
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="recordID" Type="Int32" />
</DeleteParameters>
</asp:sqldatasource>
使用GridView
<asp:TemplateField HeaderText="Month" ControlStyle-Width="100" HeaderStyle-Width="120" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<%# Eval("theMonth")%>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="TBX_theMonth" runat="server" Text='<%# Bind("theMonth")%>' />
</EditItemTemplate>
答案 0 :(得分:0)
因为它是在没有requierd的第一个代码示例中实现的
//your connection string here
SqlConnection con = RobCS_109.RDB.HentlConn;
con.Open();
string updateCMD = dsWorkDayPerMonth.UpdateCommand;
DataSet ds = new DataSet();
SqlDataAdapter da;
//use a select command and SqlConnection
da = new SqlDataAdapter(dsWorkDayPerMonth.SelectCommand, con);
//same here i have used all values recived in the example(top one)code
// event -RowUpdating above, then i am using
//stored sqlUpdate string for the command below
da.UpdateCommand = new SqlCommand(SQLUP);
da.Fill(ds, "tblWorkDayPerMonth");
dsWorkDayPerMonth.Update();
con.Close();
现在它确实有效,如果您在更新事件时遇到问题,可以在此处进行尝试
我将在稍后进一步尝试通过using
状态进行改进,一旦我将学习如何
