沒有從數據庫中獲取數據到gridview

當數據綁定到gridview時我沒有得到任何東西。誰能幫忙？沒有從數據庫中獲取數據到gridview

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="1000px" AllowPaging="True" PageSize="8" `CssClass="Grid" AlternatingRowStyle-CssClass="alt" PagerStyle-CssClass="pgr"> 
    <AlternatingRowStyle CssClass="alt"></AlternatingRowStyle> 
    <PagerStyle CssClass="pgr"></PagerStyle> 
</asp:GridView>

C＃

SqlCommand cmd1 = new SqlCommand("SELECT cars.carid, cars.make, cars.model, cars.condition, cars.amount, img.img FROM cars INNER JOIN img ON cars.carid = img.imgid where model = '" + mod + "' and make = '" + mak + "' and variant = '" + var + "' and color = '" + col + "' and condition = '" + cond + "'",con); 
SqlDataAdapter sda1 = new SqlDataAdapter(cmd1); 
DataTable dt = new DataTable(); 

sda1.Fill(dt); 
GridView1.DataSource = dt; 
GridView1.DataBind();

是否有錯誤？你看到dt中的數據了嗎？ – Sajeetharan

沒有錯誤..空白頁面顯示 – Samsam

設置AutoGenerateColumns="True"否則，你需要定義列和綁定。

仍然沒有顯示任何東西 – Samsam

更改您的SQL爲「SELECT cars.carid，cars.make，cars.model，cars.condition，cars.amount，img.img FROM cars INNER JOIN img ON cars.carid = img.imgid「運行並檢查輸出 – Damith

哦，是的，現在得到輸出，.. – Samsam
