我正在添加一个GridView&然后从SQL Server数据库中显示数据。问题是GridView没有在带有或没有数据的浏览器中显示。

I'm adding a GridView & then showing data in it from a SQL Server database. The problem is that the GridView is not displaying in the browser with or without data.

<pre> <asp:GridView ID="grdLocation" runat="server" AutoGenerateColumns="False" onrowdatabound="grdLocation_RowDataBound" onrowdeleted="grdLocation_RowDeleted" Width="100%" CssClass="grid-view" EnableModelValidation="True" ViewStateMode="Enabled"> <Columns> <asp:TemplateField HeaderText="Location Name"> <ItemTemplate> <asp:Label ID="lblShowLocationName" runat="server" Text='<%# Eval("Name") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtEditLocationName" runat="server" Text='<%# Eval("Name") %>'></asp:TextBox> <asp:RequiredFieldValidator ID="rfvLocationName" runat="server" ControlToValidate="txtEditLocationName" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="LocationUpdate"></asp:RequiredFieldValidator> <%--<asp:RegularExpressionValidator ID="rexvLocationNameEdit" runat="server" ControlToValidate="txtEditLocationName" SetFocusOnError="true" ValidationGroup="Location" ValidationExpression="^[a-zA-Z ]*$" ErrorMessage="Only Alphabets Allowed" Display="Dynamic"></asp:RegularExpressionValidator>--%> </EditItemTemplate> <HeaderStyle HorizontalAlign="Left" VerticalAlign="Middle" /> <ItemStyle HorizontalAlign="Left" VerticalAlign="Middle" /> </asp:TemplateField> <asp:TemplateField HeaderText="Location Code"> <ItemTemplate> <asp:Label ID="lblShowLocationCode" runat="server" Text='<%# Eval("Code") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtEditLocationCode" runat="server" Text='<%# Eval("Code") %>' ></asp:TextBox> </EditItemTemplate> <ItemStyle HorizontalAlign="Left" VerticalAlign="Middle" /> </asp:TemplateField> <asp:TemplateField> <ItemTemplate> <asp:ImageButton ID="imgBtnshow" runat="server" ToolTip="View" CommandArgument='<%# Eval("LocationId") %>' ImageUrl="~/Images/file_edit.png" onclick="imgBtnshow_Click" /> </ItemTemplate> <EditItemTemplate> <asp:ImageButton ID="imgBtnEdit" runat="server" CommandArgument='<%# Eval("LocationId") %>' ImageUrl="~/Images/buttonsave.png" OnClick="imgBtnEdit_Click" ValidationGroup="LocationUpdate" ToolTip="Update" /> <asp:ImageButton ID="imgBtnCancel" runat="server" ToolTip="Cancel" ImageUrl="~/Images/1350368827_save_delete.png" onclick="imgBtnCancel_Click"/> </EditItemTemplate> <ItemStyle Width="50px" /> </asp:TemplateField> <asp:TemplateField> <ItemTemplate> <asp:ImageButton ID="imgBtnDelete" runat="server" CommandArgument='<%# Eval("LocationId") %>' ImageUrl="~/Images/delete-256.png" OnClick="imgBtnDelete_Click" OnClientClick="Confirm()" ToolTip="Delete"/> </ItemTemplate> <ItemStyle Width="50px" /> </asp:TemplateField> </Columns> </asp:GridView>

我尝试过： 我不知道哪里有问题，我认为代码都可以，但为什么这个gridview在我们运行时不可见。

What I have tried: I dont know where is problem ,there is i think all ok in code but why this gridview is not visible when we run.
