Hi, I would like to persist the grid row order after the user reorder it.
I'm almost there, but i cant get the "updated" values from the grid. Whenever I access the e.DestinationGrid.Items or the grid.Items on the RowDrop event, the grid isnt updated yet, so i'm stuck with the old values.

ASPX:

<div>

<telerik:RadGrid ID="gridSubjects" runat="server" AllowPaging="True" AllowSorting="True"

AutoGenerateColumns="False" Skin="Telerik" OnDeleteCommand="gridSubjects_DeleteCommand"

OnNeedDataSource="gridSubjects_NeedDataSource" OnInsertCommand="gridSubjects_InsertCommand"

OnUpdateCommand="gridSubjects_UpdateCommand"

onrowdrop="gridSubjects_RowDrop">

<ClientSettings AllowRowsDragDrop="true" EnablePostBackOnRowClick="True">

<Selecting AllowRowSelect="True" EnableDragToSelectRows="false" />

</ClientSettings>

<MasterTableView DataKeyNames="SubjectID,Sequence" InsertItemPageIndexAction="ShowItemOnCurrentPage"

AutoGenerateColumns="false" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Adicionar"

CommandItemSettings-RefreshText="Atualizar">

<CommandItemSettings AddNewRecordText="Adicionar" RefreshText="Atualizar" ExportToPdfText="Export to PDF">

</CommandItemSettings>

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

</ExpandCollapseColumn>

<Columns>

<telerik:GridDragDropColumn Visible="true" />

<telerik:GridTemplateColumn DataField="SubjectID" HeaderText="ID" UniqueName="SubjectID"

Visible="false" ReadOnly="true">

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="Nome" UniqueName="Name" />

<telerik:GridBoundColumn DataField="Description" HeaderText="Descrição" UniqueName="Description" />

<telerik:GridHyperLinkColumn DataNavigateUrlFields="SubjectID" DataNavigateUrlFormatString="~/TrainingsControl/Topics.aspx?SID={0}"

DataTextField="TopicsCount" DataTextFormatString="Tópicos ({0})" UniqueName="TopicsCount" />

<telerik:GridHyperLinkColumn DataNavigateUrlFields="QuizID,SubjectID" DataNavigateUrlFormatString="~/TrainingsControl/QuizzesControl/Quiz.aspx?QID={0}&SID={1}"

UniqueName="Quiz" DataTextField="QuestionsCount" DataTextFormatString="Questionário ({0})" />

<telerik:GridEditCommandColumn ButtonType="ImageButton" />

<telerik:GridButtonColumn ConfirmText="Deseja realmente deletar o módulo?" ConfirmDialogType="RadWindow"

ConfirmTitle="Confirmação" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px"

ConfirmDialogWidth="220px" />

</Columns>

<EditFormSettings>

<EditColumn UniqueName="EditCommandColumn1" FilterControlAltText="Filter EditCommandColumn1 column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<StatusBarSettings LoadingText="Carregando..." ReadyText="Pronto" />

<FilterMenu EnableImageSprites="False">

</FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Telerik">

</HeaderContextMenu>

</telerik:RadGrid>

</div>

protected void gridSubjects_RowDrop(object sender, GridDragDropEventArgs e)

{

Subject subject = new Subject();

Dictionary<int, short> order = new Dictionary<int, short>();

//I tried the alternative below too

//foreach (GridDataItem item in gridSubjects.Items)

foreach (GridDataItem item in e.DestinationGrid.Items)

{

int subID = Int32.Parse(item.GetDataKeyValue("SubjectID").ToString());

short subSeq = Int16.Parse(item.GetDataKeyValue("Sequence").ToString());

order.Add(subID, subSeq);

}

using (Pro10Entities db = new Pro10Entities())

{

subject.Reorder(db, order);

}

So, can someone help?
Thanks! And sorry for the english!
