About ajax in gridview

I have solved it
bu=y taking image controls also in update panel
Thanks for your reply

Add an temp column having a label. update the label column with the image url. See if the text of label is updating if yes, then you have to look at your image url it may not be pointing to the exact location of image. other wise your updatepanel is having problem in updating the content.

Thanks.

I am not getting why it is not working
i am fetching image path on checked changed event of radiobutton and when i kept beak point then it shows me image url is coming but image is not displaying in image control

and coding for checke changed event
  Protected Sub check_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)

        myds = DirectCast(ViewState("dsdata"), DataSet)

        Dim chkbox As CheckBox = CType(sender, CheckBox)
        Dim Grow As GridViewRow = CType(chkbox.NamingContainer, GridViewRow)

       
        If (chkbox.Checked = True) Then
            Dim check As String = myds.Tables(0).Rows(0)(11).ToString()
            If (check = 0) Then
                btnauthorise.Enabled = True
                btnreject.Enabled = True
            End If
          
            strCureentRowIndex = Grow.RowIndex
            hdrowno.Value = strCureentRowIndex
            reqslipno = myds.Tables(0).Rows(strCureentRowIndex)(1).ToString()
            Boid = myds.Tables(0).Rows(strCureentRowIndex)(3).ToString()
            Dim path As String = SRV_ViewSignature(Boid)
            path = path.Replace("|*~|", "")
            path = "." + path
            '('|*~|', '').substring(1, ClientSign.replace('|*~|', '').length)
            imag.Visible = True
            Image2.Visible = True
            imag.ImageUrl = myds.Tables(0).Rows(strCureentRowIndex).Item("imagepath")
            Image2.ImageUrl = path
