В: У меня есть набор dropdownlists, который использовался для фильтрации данных в моем grid view.Итак, на filter button click я хочу получить доступ к хранимой процедуре базы данных и вернуть необходимые данные.
Вот мой код.И Хранимая Процедура, и html для gridview на всякий случай его тоже неправильно. my .cs:
public partial class Animals : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public string FormatURL(object strArgument)
{
return ("readrealimage.aspx?id=" + strArgument);
}
protected void btnFilter_Click(object sender, EventArgs e)
{
SqlConnection MyConnection = new
SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);
SqlCommand command = new SqlCommand("sp_SearchAnimals", MyConnection);
if (AnimalTypeDDL.Text != "Dont Mind")
{
AnimalTypeDDL.Text = command.Parameters["@Type_of_Animal"].Value.ToString();
}
if (CrossBreedDDL.Text != "Dont Mind")
{
CrossBreedDDL.Text = command.Parameters["@CrossBreed"].Value.ToString();
}
if (SexDDL.Text != "Dont Mind")
{
SexDDL.Text = command.Parameters["@Sex"].Value.ToString();
}
if (SizeDDL.Text != "Dont Mind")
{
SizeDDL.Text = command.Parameters["@Size"].Value.ToString();
}
if (AgeDDL.Text != "Dont Mind")
{
AgeDDL.Text = command.Parameters["@Age"].Value.ToString();
}
if (LocationDDL.Text != "Dont Mind")
{
LocationDDL.Text = command.Parameters["@Location"].Value.ToString();
}
if (RescueDDL.Text != "Dont Mind")
{
RescueDDL.Text = command.Parameters["@Name"].Value.ToString();
}
if (ChildrenDDL.Text != "Select one")
{
ChildrenDDL.Text = command.Parameters["@Children"].Value.ToString();
}
if (OtherCatsDDL.Text != "Select one")
{
OtherCatsDDL.Text = command.Parameters["@OtherCats"].Value.ToString();
}
if (OtherDogsDDL.Text != "Select one")
{
OtherDogsDDL.Text = command.Parameters["@OtherDogs"].Value.ToString();
}
GridView1.DataSource = ds;
GridView1.DataBind();
if (GridView1.Rows.Count >= 1)
{
Panel1.Visible = true;
GridView1.Visible = true;
lblMsg.Visible = false;
}
else if (GridView1.Rows.Count < 1)
{
GridView1.Visible = false;
Panel1.Visible = false;
lblMsg.Text = "Your search criteria returned no results.";
lblMsg.Visible = true;
}
command.CommandType = CommandType.Text;
command.Connection.Open();
SqlDataReader MyDataReader = command.ExecuteReader();
MyConnection.Close();
}
protected void buttonClear_Click(object sender, EventArgs e)
{
AnimalTypeDDL.Text = "Don't Mind";
CrossBreedDDL.Text = "Don't Mind";
SexDDL.Text = "Don't Mind";
SizeDDL.Text = "Don't Mind";
AgeDDL.Text = "Don't Mind";
LocationDDL.Text = "Don't Mind";
RescueDDL.Text = "Don't Mind";
}
}
моя хранимая процедура:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[sp_SearchAnimals]
(
@Type_of_Animal nvarchar(50),
@CrossBreed nvarchar(50),

@Size nvarchar(50),
@Age nvarchar(50),
@Location nvarchar(50),
@Name nvarchar(50),
@Children nvarchar(50),
@OtherCats nvarchar(50),
@OtherDogs nvarchar(50),
@Details nvarchar(300)
)
AS
BEGIn
SELECT
AD.Location,AD.Details, R.Name,
I.Content
FROM
AnimalDetails As AD INNER JOIN
Images As I ON AD.ImageId = I.ImageId,
AnimalDetails As DA INNER JOIN RescueDetails As R ON DA.RescueId = R.RescueId
WHERE
(@Type_of_Animal is NUll OR AD.Type_of_Animal = @Type_of_Animal) AND
