在Gridview中启动存储过程

Question

I have a problem with adding column into GridView , which will trigger a start of a stored procedure.

I'm trying to make a library application.

I am displaying available books in a GridView and I need to add a new column from which it will hold the trigger of a stored procedure and get column id_book , as parameter for the stored procedure.

This is the output with my notes. What do I need. Thank you for help.

• Add a new column Lend book.
• In every column have a link that will trigger stored procedure and get id_book from current row.

Part of my gridview markup:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="id_book" DataSourceID="SqlDataSource1">
    <Columns>
        <asp:BoundField DataField="id_book" HeaderText="id_book" InsertVisible="False" ReadOnly="True" SortExpression="id_book" />
        <asp:BoundField DataField="book_name" HeaderText="book_name" SortExpression="book_name" />
        <asp:BoundField DataField="id_author" HeaderText="id_author" SortExpression="id_author" />
        <asp:CheckBoxField DataField="state" HeaderText="state" SortExpression="state" />
    </Columns>
</asp:GridView>

My stored procedure:

CREATE PROCEDURE [dbo].[lendBook_sp]
    @id_reader int,
    @id_book int
AS
BEGIN
    INSERT INTO dbo.lendBook (id_book, id_reader, lendDate)  
    VALUES (@id_book, @id_reader, GETDATE())

    UPDATE dbo.book
    SET state = 0
    WHERE id_book = @id_book
END

Here I have edited your HTML code to add column to the Grid

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="id_book" DataSourceID="SqlDataSource1" OnRowCommand="gridView_RowCommand" >
<Columns>
    <asp:BoundField DataField="id_book" HeaderText="id_book" InsertVisible="False" ReadOnly="True" SortExpression="id_book" />
    <asp:BoundField DataField="book_name" HeaderText="book_name" SortExpression="book_name" />
    <asp:BoundField DataField="id_author" HeaderText="id_author" SortExpression="id_author" />
    <asp:CheckBoxField DataField="state" HeaderText="state" SortExpression="state" />

    <asp:ButtonField CommandName="EditRow" Text="Lend" CausesValidation=false></asp:ButtonField>
</Columns>

Below is the C# code for the event which will be called when the user clicks on the "Lend" link.

 protected void gridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("EditRow"))
    {
        int _bookIDEdit = Convert.ToInt32(GridView1.DataKeys[Convert.ToInt32(e.CommandArgument.ToString())].Values["id_book"].ToString());

    }
}

After getting the BookID to the intege variable, you can call the StoredProcedure.
