I had a \[code\]gridview\[/code\] in which there is a \[code\]TemplateField\[/code\] associated with a \[code\]LinkButton\[/code\] in \[code\]ItemTemplate\[/code\] with \[code\]CommandName\[/code\] as "Edit". When ever a user clicks on the \[code\]LinkButton\[/code\] it opens a ModalPOp Up to edit the current row records of the grid.For the first time it is working fine and as the modalPopUp is closed and user again clicks on the same LinkButton, it is not working a getting \[code\]object reference not set to an instance of an object\[/code\] exception. After debugging i found that for the second time their is a Label \[code\]lblUserID\[/code\] in the current selected row is not initializing. Please suggest me that how i fix this issue as it is very urgent.Please find the Code below:-\[code\]<cc1:GridView ID="gvUser" runat="server" AutoGenerateColumns="False" AllowSorting="True" CssClass="grid" OnDataBound="gvUser_DataBound" DataSourceID="odsUserDetails" AllowPaging="True" ShowFooter="false" OnRowCancelingEdit="gvUser_RowCancelingEdit" OnRowCommand="gvUser_RowCommand" OnRowDeleting="gvUser_RowDeleting" OnSelectedIndexChanged="gvUser_SelectedIndexChanged" OnRowDataBound="gvUser_RowDataBound" Height="385px" Width="900px" EnableViewState="false"> <AlternatingRowStyle CssClass="altrowstyle" /> <HeaderStyle CssClass="headerstyle" /> <RowStyle CssClass="rowstyle" Wrap="false" /> <EmptyDataRowStyle BackColor="#edf5ff" Height="300px" VerticalAlign="Middle" HorizontalAlign="Center" /> <Columns> <asp:TemplateField HeaderText="UserID" SortExpression="userID" HeaderStyle-Font-Bold="true" HeaderStyle-Font-Names="Calibre" HeaderStyle-ForeColor="White" Visible="false"> <ItemTemplate> <asp:Label ID="lblUserID" runat="server" Text='<%#Eval("userID") %>' CssClass="GridContent" /> </ItemTemplate> <EditItemTemplate> <asp:Label ID="lblEditUserID" runat="server" Text='<%#Eval("userID") %>' Style="width: 50px;" CssClass="GridContent" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="E Code" SortExpression="userecode" HeaderStyle-Font-Bold="true" HeaderStyle-Font-Names="Calibre" HeaderStyle-ForeColor="White" ItemStyle-Width="100px"> <ItemTemplate> <asp:Label ID="lblUserECode" runat="server" Text='<%#Eval("UserECode") %>' CssClass="GridContent" /> </ItemTemplate> <FooterTemplate> <asp:TextBox ID="txtAddECode" runat="server" Style="width: 50px;" CssClass="GridContent" /> <asp:RegularExpressionValidator ID="REVAddECode" runat="server" ControlToValidate="txtAddECode" ErrorMessage="*" Style="color: Red;" ValidationExpression="^\d+$" ToolTip="E Code must be numeric value only."> </asp:RegularExpressionValidator> <asp:RequiredFieldValidator ID="RFVAddECode" runat="server" ErrorMessage="*" ControlToValidate="txtAddECode" Style="color: Red;" ToolTip="E CodeCan't be left empty."> </asp:RequiredFieldValidator> </FooterTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="User Name" SortExpression="username" HeaderStyle-Font-Bold="true" HeaderStyle-Font-Names="Calibre" HeaderStyle-ForeColor="White" ItemStyle-Width="150px"> <ItemTemplate> <asp:Label ID="lblUserName" runat="server" Text='<%#Eval("UserName") %>' CssClass="GridContent" /> </ItemTemplate> <FooterTemplate> <asp:TextBox ID="txtAddUserName" runat="server" Style="width: 150px;" CssClass="GridContent" /> <asp:RequiredFieldValidator ID="RFVAddUserName" runat="server" ErrorMessage="*" ControlToValidate="txtAddUserName" Style="color: Red;" ToolTip="User Name can't be left empty."> </asp:RequiredFieldValidator> </FooterTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Enable/Disable" SortExpression="IsFlagEnabled" HeaderStyle-Font-Bold="true" HeaderStyle-Font-Names="Calibre" HeaderStyle-ForeColor="White"> <ItemTemplate> <asp:Label ID="lblIsFlagEnabled" runat="server" Text='<%# (bool)Eval("IsFlagenabled") == true ?
