[Solved] How to select related item in GridDropDownColumn when another GridDropDownColumn 's selectedindex changes.

[Kem Arda]

I have two GridDropDownColumn that resides in my RadGrid. When i select an item in the first one i wantto dislay related item in the second one over the same ID that is stored on both GridDropDownColumn 's DataField and ListValueField property.

And here are my GridDropDownColumns:

<telerik:GridDropDownColumn DataField="HizmetId" DataSourceID="LLBLGenProDataSourceHizmet"
                        HeaderText="Hizmet Adı" ListTextField="HizmetAdi" ListValueField="HizmetId"
                        UniqueName="HizmetId" ColumnEditorID="GridDropDownColumnEditor1"  >
                    <ItemStyle Width="400px"></ItemStyle>
                    </telerik:GridDropDownColumn>


      <telerik:GridDropDownColumn DataField="HizmetId" DataSourceID="LLBLGenProDataSourceHizmet"
                        HeaderText="Tutarı" ListTextField="Tutar" ListValueField="HizmetId"
                        UniqueName="TutarGoster" ColumnEditorID="GridDropDownColumnEditor2"  ReadOnly = "true">
                    <ItemStyle Width="400px"></ItemStyle>
                    </telerik:GridDropDownColumn>

When i select a service from the first GridDropDownColumn i wantto display the price of it in the second one.
