                        <table style="width:300px">
                        <tr>
                    <td style="width:250px;" >
                        <telerik:RadUpload ID="RadUpload1"  runat="server"   InitialFileInputsCount="1"
                        AllowedFileExtensions=".png" ControlObjectsVisibility="None"  Width="222px" Skin="WebBlue"  />
                    </td>
                    </tr>
                    </table>
                    </div>
                    </EditItemTemplate>

This demo should be of help to you.

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/validation/defaultcs.aspx

You need to set the ValidationSettings of the RadGrid.

I hope that helps.

Thnx for your reply
I tried the demo as
put ValidationGroup="imageEditorValGroup" for radgrid

<ValidationSettings ValidationGroup="imageEditorValGroup" EnableValidation="true" CommandsToValidate="PerformInsert,Update" />

and an other point at code behind i bind a custom validator as

 protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                RadUpload editorRadUpload = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("Upload").ContainerControl.FindControl("RadUpload1") as RadUpload;
                TableCell cell = (TableCell)editorRadUpload.Parent;
                CustomValidator validator = new CustomValidator();
                validator.ErrorMessage = "Please select file to be uploaded";
                validator.ClientValidationFunction = "validateRadUpload";
               // validator.ValidationGroup = "imageEditorValGroup";
                validator.Display = ValidatorDisplay.Dynamic;
                cell.Controls.Add(validator);
            }
        }

any button clicked on the page that contains usercontrol which includes the radgrid  is not go to validate function
but also inside grid any validate function fired...
so i found a way like this
i gived validationgroup for the controls outside grid this accomplished what i want ,for now..
