2. Export to functionality (PDF|Excel|etc) is not working

Nothing happens when we click on any of the export to excel or export to CSV , ... buttons.

The code snippet of the grid we are using is as below :-

<telerik:RadGrid AutoGenerateColumns="false" ID="grdxyz" runat="server" AllowPaging="True" AllowSorting="True" OnNeedDataSource="grdSearchResults_NeedDataSource" TabIndex="36" >

<ExportSettings HideStructureColumns="False" ExportOnlyData="False" IgnorePaging="false" OpenInNewWindow="true" FileName="MyRecord">

</ExportSettings>

<MasterTableView PageSize="10" TableLayout="Auto" Width="100%" CommandItemDisplay="Top" DataKeyNames="myid">

<CommandItemSettings ShowAddNewRecordButton="false" ShowRefreshButton="true" ShowExportToPdfButton="true" ShowExportToCsvButton="true" ShowExportToExcelButton="true" ShowExportToWordButton="true" />

Our page hierarchy is as follows. We have a master page which has a contentTemplate. On the child page we have a RadAjaxPanel and the above RadGrid is placed inside this RadAjaxPanel on child page. Has the ajaxification of the grid anything to do with these ??

Also we are using the latest version of telerik i.e v.2011.2.712.40.

Let me know accordingly.

Add new field e exec a custom query in radfilter

Hi everyone.

I'm looking for a solution to add a new field to my radfilter, and when this field be selected, I want to exec a especific query in my database.

Ex:

I have a grid (connected to the filter) with 3 fields:

Customer, Company, Salary --> This works perfectly with the filter.

What I want is to add a field called "All" that doesn't appear in grid, but is showed in filter. When the user select this field and apply filtering, I want to exec my custom stored procedure and bind the grid with the data retrieved.

What's the best way?

Thanks in advance.

Imcomprehensive probleme with LoadSettings/SaveSettings

I've got a RadFilter.
I try to save expressions with SaveSettings(), no problems. I can save the string value in a database column.
I precise I have my own FilterEditorTemplate (which is a RadControl with specific business databinding).

When i try a LoadSettings on this string value, I've got this response :
Reference is not set to an instance of an object with this stacktrace :
à Telerik.Web.UI.RadFilterDataFieldEditor.CreateEditorFrom(RadFilterDataFieldEditor baseEditor) à Telerik.Web.UI.RadFilterSingleExpressionItem.SetupFunctionInterface(Control container) à Telerik.Web.UI.RadFilterExpressionItem.CreateFunctionalInterface() à Telerik.Web.UI.RadFilter.CreateFilterItems() à Telerik.Web.UI.RadFilter.CreateControlHierarchy() à Telerik.Web.UI.RadFilter.CreateChildControls() à System.Web.UI.Control.EnsureChildControls()

I precise I am with an objectstateformater for the load and save settings. I tried with binaryformat too and the exception moves into :
serialized data are invalid.

Is it because i've got my own editor ?

Can you help me ?

Controls added to a RadNotification in RadAjaxPanel Page_Init don't persist values in Viewstate

Hi folks,

I may be doing something stupid here, but I've spent the morning grinding my teeth long enough that I've decided to ask someone else to point out my error :)

I have a RadNotification, in a RadAjaxPanel:

<telerik:RadAjaxPanel ID="notificationPanel" runat="server" ViewStateMode="Enabled">

<telerik:RadNotification ID="RadNotification1" KeepOnMouseOver="true" runat="server" VisibleOnPageLoad="false" ContentScrolling="Auto"

Width="400" Height="300" TitleIcon="none" ContentIcon="none" Animation="Fade" EnableRoundedCorners="true" EnableShadow="true" Title="Notification Title" ShowCloseButton="true" Pinned="true" Opacity="80"

AutoCloseDelay="3000" Position="TopRight" OffsetX="-50" OffsetY="50" VisibleTitlebar="true" style="z-index: 35000;">

<ContentTemplate>

<asp:Table ID="shoppingCartTable" runat="server" Width="380" ViewStateMode="Enabled">

</asp:Table>

<asp:Button ID="checkoutButton" runat="server" Text="Convert" OnClick="btnCheckout_Click" />

</ContentTemplate>

</telerik:RadNotification>

</telerik:RadAjaxPanel>

A method (in another RadAjaxPanel) creates controls inside "shoppingCartTable" in the contenttemplate of the RadNotification.
The method which fills the table is:

private void FillCartTable()

{

RadNotification1.Title = "Purchase order cart";

if (Session["PurchaseOrderCart"] == null)

{

Session["PurchaseOrderCart"] = new Dictionary<long, Dictionary<long, PurchaseOrderLine>>();

}

Dictionary<long, Dictionary<long, PurchaseOrderLine>> cart = (Dictionary<long, Dictionary<long, PurchaseOrderLine>>)Session["PurchaseOrderCart"];

foreach (long tenderID in cart.Keys)

{

TableHeaderRow th = new TableHeaderRow();

TableHeaderCell thc = new TableHeaderCell();

thc.ColumnSpan = 4;

thc.Text = Tender.GetTender(tenderID).Supplier.Name;

th.Cells.Add(thc);

shoppingCartTable.Rows.Add(th);

foreach (long TenderLineID in cart[tenderID].Keys)

{

PurchaseOrderLine pol = cart[tenderID][TenderLineID];

TableRow tr = new TableRow();

TableCell tc1 = new TableCell();

tc1.Text = " ";

tr.Cells.Add(tc1);

TableCell tc2 = new TableCell();

tc2.Text = pol.StockOrServiceDescription;

tr.Cells.Add(tc2);

TableCell tc3 = new TableCell();

tc3.Text = pol.QuantityOrdered + " " + pol.QuantityBase.Description + " at " + pol.Price.ToString("C", Global.currencyFormat) + " per " + pol.PricingBase.Description;

tr.Cells.Add(tc3);

TableCell tc4 = new TableCell();

Image b = new Image();

b.ImageUrl = "~/images/icons/16/delete.png";

tc4.Controls.Add(b);

CheckBox c = new CheckBox();

c.ID = "removeFromCart_" + tenderID.ToString() + ":" + TenderLineID.ToString();

c.EnableViewState = true;

c.ClientIDMode = System.Web.UI.ClientIDMode.Static;

tc4.Controls.Add(c);

tr.Cells.Add(tc4);

shoppingCartTable.Rows.Add(tr);

//sb.Append("<tr><td> </td><td>" + pol.Stock.Product.Number + " (" + pol.Stock.SizeDescription + ")" + "</td><td>" + pol.QuantityOrdered + " " + pol.QuantityBase.Description + "</td></tr>");

}

//sb.Append("</table>");

//sb.Append("<asp:Button ID='btnCheckout' runat='server' Text='Convert' OnClick='btnCheckout_Click' />");

//RadNotification1.Text = sb.ToString();

}

Showing the notification works just fine, and my content is there. That method is called in Page_Init, so each time the controls are created very early in the page lifecycle, long before any ViewState related events, and they're created with the same IDs (and same uniqueIDs) each time the page loads.

When the onclick event fires for the notificationcontrol's button, the checkboxes are all unchecked. They do exist (see the attached image) and the IDs do match the ones in viewstate. However, they're never re-populated from viewstate.... the attached image is a snapshot taken at the end of Page_Init and shows what I'd expect (Checked is false). However, it's still false after all the viewstate events, at the end of Page_Load - despite the Form values collection quite clearly containing that control's state.

I have temporarily worked around it by manually populating them in Page_Init (by traversing the Form values collection, looking for any with an ID containing "removeFromCart" and then manually assigning the checked property). But surely this isn't the right way to be doing it? Why doesn't Viewstate automatically get set on these controls, given that the ID and UniqueID properties are identical before and after a postback?

Cheers!

DatePicker not displayed in Schedular

Hi,

I am new to Telerik Schedular control. I wanted to enable the date picker property where in any of the views (day/week/month/timeline), I am able to select the date.

I see in all the demos that, just next to where "Today" is written, there is a downarrow which when clicked opens the datepicker control.

Somehow I am not able to get that downarrow displayed. Attached are both the screen shots.

Could you please help ?

Thanks,
Bhavik

Apply different filter types to different columns in a single table

In the web data grid control, there's a standard filter that allows you to do begin with, end with, etc. etc, there's also another filtering capability called "Google Like Search Ahead". Is there any way to combine these two types of filters into a single table, applying 1 filter type for one 1 column and another filter type to another column? Like so:

http://api.photoshop.com/v1.0/accounts/26ebb7aa51c44c3db1bf80fa5c347c32/assets/d3396c142f944659890be75cd80652f0/renditions/1024.jpg?md=1313588358000

All the columns use the standard filtering control except for the far right column which uses the Google like search ahead.

Is this possible?

Are there any examples of how to apply different filter types on a per column basis?

Any help would be most appreciated.
