Hello Everybody,
in my application I used a RadGrid to represent the company's founders, using 3 buttons outside the grid, how can I Insert/Edit/Delete the data in the grid, I studied the AllEditableColumns example you have done and I learned a lot from it, but my application is a little bit different, I shouldn't reflect any changes on the DB until I press the submit button, which means if I add a record the record won't be added to the database until I press submit the same applies for delete/edit operations
so I need temporialy to reflect the changes on the grid using javascript functions, but my problem is the edit/insert/delete buttons are outside the grid, so how can I show the edit form for the selected row when I press edit??? and how can I get the updated values after applying the changes?

P.S I should use javascript to show the edit form and to get the changes and to reflect them on the grid, your help is really appreciated

the grid looks like this:
<telerik:RadGrid ID="RadGrid1" GridLines="None" runat="server" AllowAutomaticDeletes="True"
            AllowAutomaticInserts="True" PageSize="10" AllowAutomaticUpdates="True" AllowPaging="True"
            AutoGenerateColumns="False"  OnDataBound="RadGrid1_DataBound">
            <PagerStyle Mode="NextPrevAndNumeric" />
            <MasterTableView Width="100%" CommandItemDisplay="TopAndBottom" DataKeyNames="FounderId"
EditMode="InPlace" HorizontalAlign="NotSet"  AutoGenerateColumns="False">
                <Columns>
                    <telerik:GridBoundColumn DataField="FounderId" HeaderText="Founder ID"
                        UniqueName="FounderId" ColumnEditorID="FounderIdColumnEditor">
                    </telerik:GridBoundColumn>
                    <telerik:GridNumericColumn DataField="FounderName" HeaderText="Founder Name"
                       UniqueName="FounderName" ColumnEditorID="FounderName ColumnEditor">
                    </telerik:GridNumericColumn>
                </Columns>
                <EditFormSettings ColumnNumber="2" CaptionDataField="Founder tName" CaptionFormatString="Edit properties of Founder {0}">
                    <FormTableItemStyle Wrap="False"></FormTableItemStyle>
                    <FormMainTableStyle GridLines="None" CellSpacing="0" CellPadding="3" BackColor="White"
                        Width="100%" />
                    <FormTableStyle CellSpacing="0" CellPadding="2" Height="110px" BackColor="White" />

        <telerik:GridTextBoxColumnEditor ID="SharesKindValueColumnEditor" runat="server"
            TextBoxStyle-Width="150px" />
        <table>
            <tr>
                <td align="left">
                    <table>
                        <tr>
                            <td>
                                <asp:ImageButton ToolTip="Add Founder" ID="btnAdd" runat="server"
                                    OnClientClick="AddNewFounder();" ImageUrl="~/Images/IconAdd_Text_Dialog.png" />
                            </td>
                            <td>
                                <asp:ImageButton ToolTip="Update Founder" ID="btnUpdate" runat="server"
                                    OnClientClick="UpdateFounderInfo();" ImageUrl="~/Images/IconEdit_Text_Dialog.png" />
                            </td>
                            <td>
                                <asp:ImageButton ToolTip="Delete Founder" ID="btnDelete" runat="server"
                                    OnClientClick="DeleteFounderInfo();" ImageUrl="~/Images/IconDelete_Text.png" />
                            </td>
                        </tr>
                    </table>
                </td>
            </tr>
        </table>

Hello Hamza,

Basically, you can update all the edited rows in the grid, as shown in this article:

http://www.telerik.com/help/aspnet-ajax/grdperformingbatchupdates.html

Another option which you can consider is demonstrated in the following example:

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

I hope this gets you started properly.

Sincerely yours,
