我正在尝试在gridview部分的末尾添加一个复选框,一旦检查它就会使用" 1"更新sql数据库。或" 0"。是的,它是用列名posFill完成的。
这是代码......
protected void gvPerson_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["sqlconnection"].ToString()))
{
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandText = "UPDATE requests SET date = @date, submitted_by = @submitted_by, position = @position, district = @district, base_store = @base_store, travel_to = @travel_to, open_til6 = @open_til6, email_add = @email_add, comments = @comments, posFill = @posFill, interviewDate = @interviewDate WHERE _id = @_id";
cmd.CommandType = CommandType.Text;
// Get the PersonID of the selected row.
string strID = gvPerson.Rows[e.RowIndex].Cells[2].Text;
string strPosition = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox1")).Text;
string strEmail_add = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox2")).Text;
string strDate = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox3")).Text;
string strSubBy = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox4")).Text;
string strDist = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox5")).Text;
string strBase = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox6")).Text;
string strTravel = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox7")).Text;
string strOpen = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox8")).Text;
string strComments = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox9")).Text;
//string strFilled = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox10")).Text;
string strIntDate = ((TextBox)gvPerson.Rows[e.RowIndex].FindControl("TextBox11")).Text;
string strLblFilled = ((Label)gvPerson.Rows[e.RowIndex].FindControl("lblFilled")).Text;
// Append the parameters.
cmd.Parameters.Add("@_id", SqlDbType.Int).Value = strID;
cmd.Parameters.Add("@position", SqlDbType.NVarChar, 50).Value = strPosition;
cmd.Parameters.Add("@email_add", SqlDbType.NVarChar, 50).Value = strEmail_add;
cmd.Parameters.Add("@date", SqlDbType.Date).Value = strDate;
cmd.Parameters.Add("@submitted_by", SqlDbType.NVarChar, 50).Value = strSubBy;
cmd.Parameters.Add("@district", SqlDbType.NVarChar, 50).Value = strDist;
cmd.Parameters.Add("@base_store", SqlDbType.NVarChar, 50).Value = strBase;
cmd.Parameters.Add("@travel_to", SqlDbType.NVarChar, 50).Value = strTravel;
cmd.Parameters.Add("@open_til6", SqlDbType.NVarChar, 50).Value = strOpen;
cmd.Parameters.Add("@comments", SqlDbType.NVarChar, 50).Value = strComments;
//cmd.Parameters.Add("@posFilled", SqlDbType.NVarChar, 50).Value = strFilled;
cmd.Parameters.Add("@interviewDate", SqlDbType.Date).Value = strIntDate;
cmd.Parameters.Add("@posFill", SqlDbType.Bit).Value = strLblFilled;
// Open the connection.
conn.Open();
// Execute the command.
cmd.ExecuteNonQuery();
}
// Exit edit mode.
gvPerson.EditIndex = -1;
// Rebind the GridView control to show data after updating.
BindGridView();
// Show the Add button.
lbtnAdd.Visible = true;
}
这是复选框的功能......
protected void posFilled_CheckChanged(object sender, System.EventArgs e)
{
if (chkFilled.Checked == true)
{ lblFilled.Text = "1"; }
else
{ lblFilled.Text = "0"; }
}
复选框位于gridview上并正常运行,但这里也是代码。
<asp:TemplateField HeaderText="Filled" SortExpression="posFill">
<EditItemTemplate>
<asp:CheckBox ID="chkFilled" runat="server" AutoPostBack="true" />
<asp:Label ID="lblFilled" runat="server" Visible="true"></asp:Label>
<%--<asp:TextBox ID="TextBox10" runat="server" Text='<%# Bind("posFilled") %>'></asp:TextBox>--%>
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkFilled2" runat="server"/>
<asp:Label ID="lblFilled" runat="server" Visible="true"></asp:Label>
<%--<asp:Label ID="Label10" runat="server" Text='<%# Bind("posFilled") %>'></asp:Label>--%>
</ItemTemplate>
提前谢谢你。我添加了一个标签,以查看响应是什么,或者它是否响应,如果确实如此,那么只使用标签内容。但不愿意。
答案 0 :(得分:1)
不是使用“1”.ToString()或“0”.ToString(),为什么不直接使用控件呢?您不需要标签。
cmd.Parameters.Add("@posFill", SqlDbType.Bit).Value = chkFilled.Checked;
编辑:
cmd.Parameters.Add("@posFill", SqlDbType.Bit).Value = ((CheckBox)gvPerson.Rows[e.RowIndex].FindControl("chkFilled")).Checked;
EDIT2:
您只有一个int列。您应该这样做以确保您输入的值与参数的数据类型匹配:
int tempInt = -1;
if (int.TryParse(strID, out tempInt))
{
cmd.Parameters.Add("@_id", SqlDbType.Int).Value = tempInt;
cmd.ExecuteNonquery();
}
实际上,在尝试执行命令之前,应该验证所有数据。您应该为所有参数分配正确的数据类型。如果你传递一个SqlDbType.Date,你应该传递一个DateTime变量,它应该实际解析为DateTime。
