Using Navigation in place of Menu - security trimming available?

The Navigation control looks like an improvement over the conventional menu, at least in regards to responsive design.

Can this control be bound to a sitemap, and will it perform security trimming?

Export to PDF whithout writing to HttpResponse

Hallo,

The class GridTableView supplies the method ExportToPdf(). This method writes the generated PDF-Data to the Page.Response. What I need is a method/solution which doesn't writes to Page.Response and returns a byte-Array or Stream which represents the PDF. Something like that:

public Byte[] ExportToPdfAsByteArray();

Does anyone know how to realize that?

BTW: I have seen the example from Telerik where a method was attached to the GridExporting-Event to extract the PDF-Data from the GridExportingArgs and write the pdf to a file. But that isn't a solution for me because it still writes to HttpResponse and it does a Response.Redirect to the actual page.

Thanks

Oliver

Set focus on row in grid after update

I have searched the forums but hve not found anything exactly like this, so forgive if I'm asking a question that's already been answered.

I have a grid where the record is in edit mode. The user tabs from one textbox to the next, entering data. the last tab stop is the check button. When the user tabs to the check button and then hits enter, the OnUpdate code fires. But the row is updated and the row closes and the cursor goes to the next tab stop (in this case, the beginning of the page). I have used SetFocus(AcctHeaderDetail.MasterTableView) to keep the focus on the grid. It does, but the focus goes to the insert button in the grid.

What I need to do is keep the focus in the grid in such a way that the user is able to use the down arrow to move down to the next record, hit Enter and the row opens up for editing.

Ho do I manage control of what object receives the focus after the OnUpdate code behind executes?

Refer to a newly added row to radgrid outside radgrid event

I am trying to access to a new added row in radgrid which is not committed yet. Just a new row is added and user enters data. Onclick on a link on this row a new method is being invoked which updates two fields in this particular row. So when user actually click on the insert button the updated fields are saved to the db along with user entry. So I want to know how refer to this newly added row in the radgrid which is not saved yet.

GridDropDownColumn error when using AllowAutomaticLoadOnDemand="true"

I reviewed this example: http://demos.telerik.com/aspnet-ajax/grid/examples/columns-rows/columns/column-types/defaultcs.aspx and cannot seem to replicate this in my application.

<telerik:GridDropDownColumn DataField="Item_Id" DataType="System.Int32" FilterControlAltText="Filter Item_Id column" HeaderText="Item" UniqueName="Item_Id" AutoPostBackOnFilter="true" DataSourceID="EntityDataSourceItem" ListValueField="Id" ListTextField="Model" AllowVirtualScrolling="true" ShowMoreResultsBox="true" ItemsPerRequest="10" SortExpression="Item_Id" EmptyListItemText="Select" AllowAutomaticLoadOnDemand="true" DropDownControlType="RadComboBox" >

</telerik:GridDropDownColumn>

<asp:EntityDataSource ID="EntityDataSourceItem" runat="server" ConnectionString="name=autocalEntities" DefaultContainerName="autocalEntities" EnableDelete="True" EnableFlattening="False" EnableInsert="True" EnableUpdate="True" EntitySetName="items"></asp:EntityDataSource

>



Everything populates correctly on load but when I attempt to edit and retrieve a filtered list from the gridview i get the object reference not set to an instance of an object exception. Any idea what I am missing? 



Thanks,

Josh

How do I validate a GridDateTimeColumn for valid date?

I have a grid with a GridDateTimeColumn. I do InPlace editing on the grid. I need to validate that the date entered is a valid date. I can't see to determine how to do this. I tried the RequiredFieldValidator, but that doesn't work correctly. If I enter an invalid date, and click the update button, the date field gets the red box around it and the grid goes out of edit mode and reverts rebinds.

How can I flag the invalid date, notify the user the date is invalid and keep the grid in edit mode?

This is my grid.

AJAX Grid Unselectable items not refreshed

Hello,

I have a strange problem here. I have a grid where some rows are selectable and some are not based on certain criteria. The user can execute different queries to produce different results, which in-turn produces different unselectable rows. The problem is, the unselectableItemsIndex in the grid's client state is not staying in sync. The rows that were unselectable in the previous query become unselectable in the new result set. This problem seems to compound itself with each new query. In other words, it seems the unselectableItemsIndex array is just appended to.

Oh, this is all happening via AJAX.

Any help would be appreciated.

Blair
