    [CLOSED] GridPanel, SelectedRow and RowSelectionModel : Is JsonReader required to get selected row in server code?

    Hey,
    I have previously used the following code to get the selected row on the server side:

    RowSelectionModel sm = GridPanel2.SelectionModel.Primary as RowSelectionModel;
    
                if (sm.SelectedRow != null)
                {
                      // do something
                }
    In that case the store for GridPanel2 uses a JsonReader. If I use the same code, but instead of a JsonReader for the Store I use an ArrayReader, it wont work:

              <ext:Store ID="Store1" runat="server">
                                                <Reader >
                                                    <ext:ArrayReader IDProperty="Nbr">
                                                        <Fields>
                                                            <ext:RecordField Name="Nbr"></ext:RecordField>
                                                            <ext:RecordField Name="Stuff"></ext:RecordField>
                                                        </Fields>
                                                    </ext:ArrayReader>
                                                </Reader>
                                            </ext:Store>
    I just want to confirm that I cannot use the server side code as specified aboive if I do not use a JsonReader for the Store?

    Is there any way of getting the selected row in a GridPanel when using an ArrayReader?

    No, JsonReader is not required as I see it. I realize that I have an ArrayReader for another GridPanel, and I can select a row and in teh server code get the correct row.

    Problem is, I cannot get it to work on this GridPanel Im on now for some reason.

    <ext:GridPanel ID="GridPanel_solutions" runat="server" Height="150" Title="Test" >
                                        <Store>
                                            <ext:Store ID="Store_BookingResults_Solutions" runat="server" AutoDataBind="true" AutoLoad="true" OnRefreshData="TestABC">
                                                <Reader >
                                                    <ext:JsonReader IDProperty="Nbr">
                                                        <Fields>
                                                            <ext:RecordField Name="Nbr"></ext:RecordField>
                                                            <ext:RecordField Name="Score"></ext:RecordField>
                                                        </Fields>
                                                    </ext:JsonReader>
                                                </Reader>
                                            </ext:Store>
                                        </Store>
    
                                        <ColumnModel ID="ColumnModel2" runat="server">
                                            <Columns>
                                                <ext:Column ColumnID="Nbr" DataIndex="Nbr" Header="Nbr" Hidden="true"/>
                                                <ext:Column DataIndex="Score" Header="PoƤng" Width="60"/>
                                            </Columns>
                                        </ColumnModel>
                                        <SelectionModel>
                                            <ext:RowSelectionModel
                                                ID="SelectedRowModel1" 
                                                runat="server" 
                                                SingleSelect="true">
                                                <Listeners>
                                                    <RowSelect Handler="Ext.net.DirectMethods.SolutionSelected()" />
                                                </Listeners>
                                            </ext:RowSelectionModel>
                                        </SelectionModel>
                                    </ext:GridPanel>
    code behind:

     [DirectMethod]
            public void SolutionSelected()
            {
                RowSelectionModel sm = GridPanel_solutions.SelectionModel.Primary as RowSelectionModel;
    
                if (sm.SelectedRow != null) // sm.SelectedRow is always null
                {
                    // do something
                }
               
            }
    What am I missing this time?

    Hi,

    Yes, selections don't deal with Store and, respectively, Reader.

    Is the rest part of this thread totally related to the following thread?

    yes, it is!

    It was a late night, I had several things that was messing with me so I guess I sort of double-posted. Im sorry about that.

    the Delay="1" works.

    But its odd since the Delay="1" was not needed in another GridPanel/RowClick in the same project. There it just is like this:
    <Listeners>
         <RowClick Handler="Ext.net.DirectMethods.SetCustomer();"    />
    </Listeners>
    and it works. Why is that?

    Well, it's odd. Is the rest part of configuration the same? I guess - no.

    Please provide a sample to reproduce where it works without Delay="1".
