Get GridPanel rows on the store events.

[yossi]

Hi,
How can i get the grid's data from the store events?
I try the following, but it is not working!

<ext:Store ID="StoreBlockingRuleDetails" AutoLoad="true" DataSourceID="BlockingRuledetailsDataSource" runat="server" 


OnRefreshData="StoreBlockingRulesDetails_Refresh"


OnBeforeRecordInserted="StoreBlockingRulesDetails_BeforeRecoedInserted"


OnBeforeRecordUpdated="StoreBlockingRulesDetails_BeforeRecoedUpdated"


OnAfterAjaxEvent="StoreBlockingRulesDetails_AfterAjaxEvent"


OnBeforeRecordDeleted="StoreBlockingRulesDetails_BeforeRecordDeleted"


OnBeforeStoreChanged="test1" 


OnBeforeAjaxEvent="test2"


OnSubmitData="test3"


ShowWarningOnFailure="false" >


<BaseParams>


<ext:Parameter Name="DetailsGrid" Value="Ext.encode(#{BlockingRuleItemsGrid}.getRowsValues(false))" Mode="Raw" />


</BaseParams>


<Reader>


<ext:JsonReader ReaderID="BLOCK_RULE_DETAIL_ID">


<Fields>


<ext:RecordField Name="BLOCK_RULE_DETAIL_ID" Type="Int">


<Convert Handler="" Args="value,record" FormatHandler="False"></Convert>


</ext:RecordField>


<ext:RecordField Name="BLOCK_RULE_ID" Type="Int">


<Convert Handler="" Args="value,record" FormatHandler="False"></Convert>


</ext:RecordField>


<ext:RecordField Name="BLOCK_TYPE_ID" Type="Int">


<Convert Handler="" Args="value,record" FormatHandler="False"></Convert>


</ext:RecordField>


<ext:RecordField Name="BLOCK_VALUE" Type="String">


<Convert Handler="" Args="value,record" FormatHandler="False"></Convert>


</ext:RecordField>


</Fields>


</ext:JsonReader>


</Reader>


<SortInfo Field="BLOCK_TYPE_ID" Direction="ASC" />


<Listeners>


<LoadException Handler="Ext.Msg.alert('Blocking Rules - Load failed', e.message || e )" />


<CommitFailed Handler="Ext.Msg.alert('Blocking Rules - Commit failed', 'Reason: ' + msg)" />


<SaveException Handler="Ext.Msg.alert('Blocking Rules - Save failed', e.message || e)" />


<CommitDone Handler="Ext.Msg.alert('Blocking Rules - Commit', 'The data was successfully saved');" />


</Listeners>





</ext:Store>





<ext:Store ID="StoreCboxBlockRuleType" runat="server">


<Reader>


<ext:JsonReader ReaderID="BLOCK_TYPE_ID">


<Fields>


<ext:RecordField Name="BLOCK_TYPE_ID" />


<ext:RecordField Name="BLOCK_TYPE_NAME" />


</Fields>


</ext:JsonReader>


</Reader>


</ext:Store>

While BlockingRuleItemsGrid is a gridpanel.

when i try to get to the grid on one of the store event, Exception is thrown, for example:

protected void test1(object sender, BeforeStoreChangedEventArgs e)


{


Store store = (Store)sender;


string detailsGrid = store.BaseParams["DetailsGrid"];


Dictionary<string, string>[] gridData = JSON.Deserialize<Dictionary<string, string>[]>(detailsGrid);
}//Here I get Exception

Can you help me with this??

Thanks in advance!!!
Yossi.

Hi,
I just want to say that the purpose of this is to check on the before store changedevent if the grid is not empty if there is another way, it is also OK.
Thanks!
