                OnRowUpdating="grdEvaluation_Questions_RowUpdating">
                <Columns>
                    <asp:BoundField DataField="CategoryName" HeaderText="Category Name" />
                    <asp:BoundField DataField="SubCategoryName" HeaderText="SubCategory Name" />

                    <asp:BoundField DataField="PossibleAnswers" HeaderText="Possible Answers" />
                    <asp:TemplateField>
                        <ItemTemplate>
                            <asp:Button ID="btnEdit" CommandArgument='<%# Eval("QuestionID")%>' CommandName="Update"
                                runat="server" Text="Edit" />
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField>
                        <ItemTemplate>
                            <asp:Button ID="btnDelete" CommandArgument='<%# Eval("QuestionID")%>' CommandName="Delete"
                                runat="server" Text="Delete" />
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>

This is my code for bind the grid

public void GetAllEvaluation_Question()
        {
            var EvaluationQuestion = clsEvaluationQuestion.GetAllEvaluation_Question().AsQueryable();

            grdEvaluation_Questions.DataSource = EvaluationQuestion;
            grdEvaluation_Questions.DataBind();
        }

this is my DAl function

public IQueryable GetAllEvaluation_Question()
        {
            CastroDataContext objDAL = new CastroDataContext();
            var varEvaluation_Question = objDAL.sp_GetAll_Evaluation_Questions().AsQueryable();
                       
            return varEvaluation_Question;
        }

And this is my store procedure

alter PROCEDURE sp_GetAll_Evaluation_Questions
	
AS
BEGIN
	select eq.*,c.CategoryName, sc.SubCategoryName, qt.QuestionTypeDesc  from Evaluation_Questions eq

	inner join QuestionTypes qt
	on eq.QuestionTypeID=qt.QuestionTypeID

	inner join Categories c
	on eq.CategoryID =c.CategoryID

	left outer join SubCategories sc
	on eq.SubCategoryID=sc.SubCategoryID

	where eq.IsDeleted = 0
END
