How to get the data from a sessiondatasource?

How to get the data from a sessiondatasource?
I get the following scenario:

The code the .aspx is as below:

<sds:SessionDataSource

DisplayWarning = "False"

PrimaryKeyFields = "dp_key"

ProviderName = "System.Data.SqlClient"

ID = "devis"

runat = "server"

ConnectionString = "<%$ ConnectionStrings:xxxxxxxxxx_Connection %>"

ConflictDetection = "CompareAllValues"

OldValuesParameterFormatString = "original_{0}"

SelectCommand="SELECT * FROM [devis] ORDER BY dp_key"

DeleteCommand="DELETE FROM [devis] WHERE [dp_key] = ?"

InsertCommand="INSERT INTO devis(dp_codeprd, dp_nombre, dp_convives, dp_prixs, dp_prixs_unitaire) VALUES (?, ?, ?, ?, ? )"

>

<DeleteParameters>

<asp:Parameter Name="original_dp_key" Type="Int32" />

</DeleteParameters>

<InsertParameters>

<asp:Parameter Name="dp_codeprd" Type="String" />

<asp:Parameter Name="dp_nombre" Type="String" />

<asp:Parameter Name="dp_convives" Type="Int16" />

<asp:Parameter Name="dp_prixs" Type="Decimal" />

<asp:Parameter Name="dp_prixs_unitaire" Type="Decimal" />

</InsertParameters>

</sds:SessionDataSource>

This definition is used in a RadGrid. The code the .aspx is as below:

<telerik:RadGrid

ShowFooter = "false"

ID = "devis_prd"

runat = "server"

DataSourceID = "devis"

<HeaderStyle HorizontalAlign="Right" />

<ItemStyle CssClass="monto_grid" />

</telerik:GridBoundColumn>

<telerik:GridButtonColumn

ConfirmText = "Cette action permet de supprimer le produit sélectionné de votre devis. <br/><br/>Etes-vous sûr ? <br/><br/>"

ButtonType = "ImageButton"

CommandName = "Delete"

Text = "Supprimer ce produit"

UniqueName = "DeleteColumn"

ConfirmDialogType = "RadWindow"

>

<HeaderStyle Width="20px" />

<ItemStyle HorizontalAlign="Center" CssClass="MyImageButton" />

</telerik:GridButtonColumn>

</Columns>

<EditFormSettings>

<EditColumn CurrentFilterFunction="NoFilter" FilterListOptions="VaryByDataType"></EditColumn>

</EditFormSettings>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

<FilterMenu EnableTheming="True">

<CollapseAnimation Duration="200" Type="OutQuint" />

</FilterMenu>

</telerik:RadGrid>

So no problem here ...!

Then, I need to show the items found on the sessiondatasource and try the following: (the code behind the .aspx is as below):

string query_str = "SELECT * FROM [devis] order by dp_key";

DataTable dt = GetDataTable(query_str);

RadGrid_devis_panel.DataSource = dt;

RadGrid_devis_panel.DataBind();

etapa_02.Alert("--> devis_rpt_PreRender : " + dt.Rows.Count);

I do not show any item (dt.Rows.Count = 0), as I can read data from the sessiondatasource?

Thanks in advance!

Difference in Scrolling Behavior Buttons/ButtonsOver

Hi there,

I stumbled across a little, I would not go as far as to call it a problem, issue. It seems the rotator behaves differently when setting either to Buttons or ButtonsOver mode. In Buttons mode the whole viewport is scrolled after clicking the left/right arrow. In ButtonsOver-mode only one item is advanced when clicking the right/left arrow.
Is it possible to achieve said behavior with the Buttons-Mode too? To clarify I would like the Buttons-Mode NOT wich Viewpoint but Item scrolling.

Thank you for your assistance.

Webparts in the RadRotator

Hi,

I am using webparts in the Rad Rotator. I have implemented a functionality by which the user when clicks in the title of the webpart will minimize/maximise the webpart and the underlying webparts will cover up the space as they are rendered as divs. This works fine if the webparts are placed outside the RadRotator. When I place the webparts in the RadRotator the minimize and maximize of the webparts happen but the space remains the same between the webparts. Any way to overcome this.

TreeView with OpenAccessDatasource problem

Hello,

When I'm trying to use OpenAccessDataSource as the datasource of the treeview, the treeview is using wrong table.
I configured the datasource to use the Entitlement table. I attached it to treeview using the DatasourceId. It throws an exception about the Description field does not exist in the invoicelinesharing table.

<telerik:OpenAccessDataSource ID="EntitlementDS" runat="server" ObjectContextProvider="Xapt.AgilePoint.Data.SiteContextModel.SiteEntityDiagrams, Xapt.AgilePoint.Data.SiteContextModel"

TypeName="Xapt.AgilePoint.Data.SiteContextModel.Entitlement" EnableDelete="False"

EnableInsert="False" EnableUpdate="False">

</telerik:OpenAccessDataSource>

<telerik:RadTreeView runat="server" ID="tvEntitlement" DataSourceID="EntitlementDS"

DataFieldID="EntitlementId" DataFieldParentID="ParentId" DataTextField="Description">

Crash - Week view to Day view

I am getting following error with crash in loading the page when I switch from Week view to Day view in RadScheduler control. I would appreciate insight on the same please.
=========================

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
=============================
I am doing this on click of custom links on my page. and event handler for the links as follows

==============================

Binding data element in client side

<telerik:GridHyperLinkColumn DataNavigateUrlFields="EmployeeId,CertComplete" DataTextField="EmployeeId"

DataTextFormatString="Edit/Update" UniqueName="EmployeeCert"

RadAjaxManager with RadScheduler and RadGrid and RadWindow

Hi Guys,

I have the following scenario:

I have a radscheduler and a radgrid being refreshed whenever the date range is changed in the radscheduler. I am using the event Navigation completed in the radscheduler to update the data for the grid. I am using a rad window in the grid for edit/insert.
The RadAjaxManager configuration is as follows:
<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1" ClientEvents-OnRequestStart="conditionaPostback">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="radScheduler">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="radScheduler" />
                        <telerik:AjaxUpdatedControl ControlID="gdvTasks" />

                    </UpdatedControls>
                </telerik:AjaxSetting>

            </AjaxSettings>
        </telerik:RadAjaxManager>

The problem is that this way the radwindow is no more poping up when I click edit or insert in the grid.
If I remove the <telerik:AjaxUpdatedControl ControlID="gdvTasks" /> line from the ajaxmanager then the radwindow pops up but the problem is that the grid is no more refreshed automatically so I need to click on the refresh button in the grid in order for the latest data to be displayed.
One more thing is that I am adding the radwindow from code behind when the user clicks the insert or edit link buttons in the grid.

Any Help is appreciated. Thank you in advance.

ContextMenu Right click in a Listbox

When you right click on an item in the ListBox it works as expected. But if you right click in the ListBox but not on an item it gives me the following error any ideas on how to correct this?

"Microsoft JScript runtime error: 'get_item()' is null or not an object"

function showContextMenu(sender, e) {

var RadList = $find("Listbox");

var RadListSelected = RadList.get_selectedItem();

var menu = $find("cm1");

var rawEvent = e.get_domEvent().rawEvent;

menu.show(rawEvent);

e.get_item().select(); < ERROR is called on this item because object is nothing

$telerik.cancelRawEvent(rawEvent);

}

Displaying RecurrenceRule in RecurrenceEditor

I seem to have trouble using the recurrence editor to show an existing rule ready for editing.

For testing I am using:

Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click

RecurrenceEditor2.RecurrenceRuleText = TextBox1.Text

TextBox2.Text =

"Done"

End Sub

to copy the text from TextBox1 which holds the rule produced by another RecurrenceEditor (RecurrenceEditor1). I expect RecurrenceEditor2 to show the same settings as RecurrenceEditor1, but it just shows it's initial "empty" state.

Should I be doing anything else?

Thanks
John
