问题描述
当在另一个表（User_Information）中插入值时，它表示不能在表（ID）（主键）中插入空值。但我正在将价值传递给主键!!
我尝试过的事情：
我的GridView是： -
When inserting the values in another table (User_Information) it says cannot insert null values in the table for column (ID) which is primary key. But I'm passing value to the primary key!!
What I have tried:
My GridView is:-
<asp:GridView ID="GrdVwViewUser" runat="server" EnableViewState="true" BorderStyle="None" AutoGenerateColumns="false"
CssClass="col-md-4 col-xs-4 text-center">
<columns>
<asp:TemplateField HeaderStyle-CssClass="heading text-center text-info" HeaderText="Users Details" HeaderStyle-Font-Size="30px" HeaderStyle-Height="40px" ItemStyle-CssClass="form-group">
<itemtemplate>
ID : <asp:Label ID="LblID" runat="server" Text='<%#Eval("ID") %>'><br />
UserName : <asp:Label ID="LblUserName" CssClass="form-inline" runat="server" Text='<%#Eval("UserName") %>'><br />
Password : <asp:Label ID="LblPassword" runat="server" Text='<%#Eval("Password") %>'><br />
FirstName : <asp:Label ID="LblFirstName" runat="server" Text='<%#Eval("FirstName") %>'><br />
LastName : <asp:Label ID="LblLastName" runat="server" Text='<%#Eval("LastName") %>'><br />
Email : <asp:Label ID="LblEmail" runat="server" Text='<%#Eval("Email") %>'><br />
PhoneNo : <asp:Label ID="LblPhoneNo" runat="server" Text='<%#Eval("PhoneNo") %>'><br />
Location : <asp:Label ID="LblLocation" runat="server" Text='<%#Eval("Location") %>'><br />
Created_By : <asp:Label ID="LblCreated_By" runat="server" Text='<%#Eval("Created_By") %>'><br />
Gender : <asp:Label ID="LblGender" runat="server" Text='<%#Eval("Gender") %>'><br />
Date of Birth : <asp:Label ID="Lbldob" runat="server" Text='<%# Convert.ToDateTime (Eval("dob")).ToString("dd-MMM-yyyy") %>'><br />
Region : <asp:Label ID="Lblregion" runat="server" Text='<%#Eval("region") %>'><br />
Language : <asp:Label ID="Lbllang" runat="server" Text='<%#Eval("lang") %>'><br />
Deleted : <asp:Label ID="LblDeleteUser" runat="server" Text='<%#Eval("DeleteUser") %>'><br />
Registered On : <asp:Label ID="LblRegisterDate" runat="server" Text='<%# Convert.ToDateTime (Eval("RegisterDate")).ToString("dd-MMM-yyyy hh:mm tt") %>'><br />
About Me : <asp:Label ID="LblAbout" runat="server" Text='<%#Eval("about") %>'><br />
Authorised : <asp:Label ID="LblAuthorised" runat="server" Text='<%#Eval("Authorised") %>'><br />
<asp:LinkButton ID="LnkBtnApprove" runat="server" CssClass="btn-sm btn-info form-inline" CommandArgument='<%#Eval("ID") %>' OnCommand="LnkBtnApprove_Command" >Approve
</itemtemplate>
</columns>
和命令参数是： -
And Command Argument is:-
protected void LnkBtnApprove_Command(object sender, CommandEventArgs e)

long id = Convert.ToInt64(e.CommandArgument);
