使用Gridview完成SQL「INSERT INTO」命令並

我正在嘗試使用Gridview完成SQL「INSERT INTO」命令。使用Gridview完成SQL「INSERT INTO」命令並

我使用FindControl捕獲到頁腳文本框： TextBox Tempcol1 = ((TextBox)GridView1.FooterRow.FindControl("TBInsertFootercol1"));

然後將其綁定到InsertParameter在SqlDataSource1：

SqlDataSource1.InsertParameters["@col1"].DefaultValue = Tempcol1.Text;

然後將其發送給SqlDataSource1：

SqlDataSource1.Insert();

aspx

<asp:GridView ID="GridView1" 
    runat="server" 
    DataSourceID="SqlDataSource1" 
    AutoGenerateColumns="false" 
    DataKeyNames="idt"

，問題是... – Dalorzo 2014-09-01 02:42:31

的 '@' 爲什麼它什麼也不做。它不會插入到我添加的值的另一行中。根本沒有錯誤陳述。 – noviscientia 2014-09-01 02:44:54

調試你的代碼，在'SqlDataSource1.Insert（）;'處放置斷點，並且在每次檢查'SqlDataSource1.InsertParameters'的值時，看看它們是否有價值，然後告訴我們，祝你好運 – Farrokh 2014-09-01 04:17:53

嘗試下探從InsertParamters聲明

SqlDataSource1.InsertParameters["datetime"].DefaultValue = Convert.ToString(DateTime.Now); 
SqlDataSource1.InsertParameters["col1"].DefaultValue = Tempcol1.Text; 
SqlDataSource1.InsertParameters["col2"].DefaultValue = Tempcol2.Text; 
SqlDataSource1.InsertParameters["col3"].DefaultValue = Tempcol3.Text;
