GridPanel SelModel

[Timothy]

Quick question,

On PostBack how would I get the selected items from the GridPanel with the following example:

                                <ExtJS:Store ID="Categories"
                                    runat="server"
                                    AutoLoad="True">
                                    <Reader>
                                        <ExtJS:JsonReader ReaderID="CategoryId">
                                            <Fields>
                                                <ExtJS:RecordField Name="CategoryId" />
                                                <ExtJS:RecordField Name="Translation" />
                                            </Fields>
                                        </ExtJS:JsonReader>
                                    </Reader>
                                </ExtJS:Store>
                                <ExtJS:GridPanel ID="dgCategories"
                                    runat="server"
                                    StoreID="Categories"
                                    AutoExpandColumn="Translation"
                                    AutoHeight="True"
                                    StripeRows="True"
                                    TrackMouseOver="True"
                                    Width="325">
                                    <ColumnModel>
                                        <Columns>
                                            <ExtJS:Column ColumnID="Translation" DataIndex="Translation" Header="Category" MenuDisabled="True" />
                                        </Columns>
                                    </ColumnModel>
                                    <SelModel>
                                        <ExtJS:CheckboxSelectionModel ID="CategorySelection" runat="server" />
                                    </SelModel>
                                </ExtJS:GridPanel>

Hi Timothy,

There is a problem with this feature. We're fixing and will post a code sample demonstrating how to use.

[Timothy]

Great thanks Geoffrey!

Would be awesome if from AjaxEvents (or regular postback) if I could get and set the selected items :)

Cheers,
Timothy

[geoffrey.mcgill]

Yes, this will be easily possible. The missing feature was just an oversight on our part.*

An update will be available shortly.

[Timothy]

Thanks any update on this one? I've got a GridPanel waiting for some functionality :)

Cheers,
Timothy

Hi Timothy,

Sorry, not ready yet, we working on it and will commit soon

[geoffrey.mcgill]

Hi Timothy,

We're close to finishing up the new functionality for getting the selected rows. The functionality will return a <List> filled with property values that from the "ReaderID" property as defined in the <ext:Store>. We'll have some code demonstrating this functionality available shortly which should clarify everything.

On a related note, the <SelModel> property on the <ext:GridPanel> has been renamed to <SelectionModel>.

Example

// Old
<ext:GridPanel 
    ID="GridPanel1" 
    runat="server" 
    StoreID="Store1"
    Title="Company List"
    Width="600"
    Height="350">
    <SelModel>
        <ext:CheckboxSelectionModel runat="server" />
    </SelModel>
</ext:GridPanel>


// New
<ext:GridPanel 
    ID="GridPanel1" 
    runat="server" 
    StoreID="Store1"
    Title="Company List"
    Width="600"
    Height="350">
    <SelectionModel>
        <ext:CheckboxSelectionModel runat="server" />
    </SelectionModel>
</ext:GridPanel>

On another somewhat related note, we have also renamed the <Bbar> property to <BottomBar>.

Example

// Old
<Bbar>
    <ext:PagingToolBar ID="PagingToolBar1" runat="server" />
</Bbar>


// New
<BottomBar>
    <ext:PagingToolBar ID="PagingToolBar1" runat="server" />
</BottomBar>

Great Geoffrey,

I think getting back a List of ReaderID values is a great solution. How will you handle setting the selection; same way?

Looking forward to the example.

Cheers,
Timothy

[Timothy]

Any ETA on its completion? I know you said close, wouldn't mind give it a smack around :)

Cheers,
Timothy

[Timothy]

What's in SVN so far is great guys; thanks so much :)

Cheers,
Timothy
