Please refer the code for updating the item in gridview:

Protected Sub gvCarDetails_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs)
        Dim selectRow As GridViewRow
        selectRow = gvCarDetails.Rows(e.RowIndex)

        Dim txtCarMakeID As TextBox
        Dim carMakeID As Integer
        txtCarMakeID = selectRow.FindControl("txtCarMakeID")
        carMakeID = Convert.ToInt32(txtCarMakeID.Text)

        Dim txtCarMakeName As TextBox
        Dim carMakeName As String
        txtCarMakeName = selectRow.FindControl("txtCarMakeName")
        carMakeName = txtCarMakeName.Text


        Dim txtCarModelID As TextBox
        Dim carModelD As Integer
        txtCarModelID = selectRow.FindControl("txtCarModelID")
        carModelD = Convert.ToInt32(txtCarModelID.Text)


        Dim txtCarModelName As TextBox
        Dim carModelName As String
        txtCarModelName = selectRow.FindControl("txtCarModelName")
        carModelName = txtCarModelName.Text

        
        txtCarModelName = gvCarDetails.Rows(e.RowIndex).FindControl("txtCarModelName")
        carModelName = txtCarModelName.Text


        UpdateCarDetails(carModelD, carModelName)

        FillCarDetails()


    End Sub

        Try
            marrParm(0) = New SqlParameter("@carModelId", SqlDbType.Int)
            marrParm(0).Value = carModelId

            marrParm(1) = New SqlParameter("@carModelName", SqlDbType.VarChar, 64)
            marrParm(1).Value = carModelName

            With mObjBLL

                .ParametersList = marrParm
                .AddUpdateMasters()

                If .IsRedirect = False Then
                    lblMsg.Text = "Error: Updating Data: " & .ErrorMessage
                    Exit Sub
                End If

            End With


        Catch ex As Exception
        Finally
            marrParm = Nothing
        End Try
    End Sub

推荐答案

为上述问题找到解决方案.....

在页面加载时填充GridView时，调用在Page.IsPostBack = False
中填充griwview的方法
例如:

Got the solution for the above problem.....

when populating the GridView on Page Load, call the method to populate the griwview in Page.IsPostBack = False

Eg:

<br />
If Page.IsPostBack = False Then<br />
            FillCarDetails()<br />
        End If<br />
