How to stop autopostback on calendar view changed

Hi,
I've got a RadCalendar control that has autopostback set to true. I am handling the event that fires when the selected date is changed on the rad calendar. However, when the calendar view is changed by using the fast navigation controls, a post back occurs. How do I stop that postback from happening?

Thanks

Custom field for appointment form

Hi,

Seems like Telerik Scheduler is quite good.

I need extra option though.

I need to have couple of extra fields available for the form where appointment gets created. Those fields are in different underlying tables so I need the way to have those fields values pushed into those tables. Then I need to have them populated back into edit appointment form.

I would appreciate if you can get me a snippet.

Regards, Anvar

Edit Mode Resets Column Editors

I have a scenario in which I have a RadGrid with in-place editing enabled. Several of the columns have custom editors referenced by the ColumnEditorID attribute, and all of the column editors in the grid are Telerik controls. I am catching the ItemCommand event in the code-behind to process the grid commands. The AllowMultiRowEdit attribute of the grid is set to false.

If I click Edit on one of the rows, the row goes into Edit mode correctly, and all of the formatting rules for each column editor are respected (e.g. I have a currency column that displays with a dollar sign and two decimal places, an integer column that displays with no decimal places and no commas, and the numeric columns are aligned right). Now, if I click Edit on a different row, the row that was previously in Edit mode exits edit mode and the second row that was clicked goes into Edit mode, again, as expected. However, the column editors in the second row have now lost the formatting rules. The currency column displays with no dollar sign, the integer column displays with decimal places and commas, and the numeric columns are no longer aligned right.

Note that the formatting is only lost on the editors themselves. The cells, when in view mode, retain their appropriate formatting.

Here is my grid:

<telerik:RadGrid

ItemCommand only raised in IE

Not exactly accurate, but telerik won't let me edit the title.

The grid is a list of documents the user has stored. To view a stored document, I created the view link; within the ItemCommand event handler I create a file and stream it back to the user as shown below. However, the javascript to open a window to facilitate the streaming never gets invoked (except in IE browsers).

This is in a user control, although I don't think that's important. Here's the mark-up:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

var mediaList = {};

mediaList.get_AddDocumentModalUrl = function mediaList_getAddDocumentModalUrl() {

return '<%= Page.ResolveClientUrl("~/MediaLibrary/Modals/AddDocument.aspx") %>';

}

mediaList.get_ViewDocumentModalUrl = function mediaList_getViewDocumentModalUrl(mimeType) {

var url = '<%= Page.ResolveClientUrl("~/MediaLibrary/Modals/ViewDocument.aspx") %>' + '?type=' + mimeType;

return url;

}

//On insert and update buttons click temporarily disables ajax to perform upload actions

//See http://demos.telerik.com/aspnet-ajax/controls/examples/integration/raduploadinajaxifiedgrid/defaultcs.aspx?product=upload

//for a more detailed description of why we need this.

function conditionalPostback(sender, eventArgs) {

var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");

if (eventArgs.get_eventTarget().match(theRegexp)) {

var upload = $find(window['UploadId']);

//AJAX is disabled only if file is selected for upload (i.e., new documents)

if (upload != null && upload.getFileInputs()[0].value != "") {

eventArgs.set_enableAjax(false);

}

function validateRadUpload(source, e) {

e.IsValid = false;

var upload = $find(source.parentNode.getElementsByTagName('div')[0].id);

var inputs = upload.getFileInputs();

for (var i = 0; i < inputs.length; i++) {

//check for empty string or invalid extension

And the ItemCreated event handler, where I set up the "View" link.

if (ajaxMgr != null)

{

}

And here's where I handle the ItemCommand:

{

if (e.CommandName == RadGrid.InitInsertCommandName)

{

e.Canceled = true;

e.Item.OwnerTableView.InsertItem(new PartnerDocument());

}

else if (e.CommandName.Equals("View"))

{

BernardClientContext bcc = BuildClientContext();

DocumentService ds = new DocumentService(new DocumentRepository(bcc));

Document doc = ds.GetById(new Guid((string)e.CommandArgument));

string filePath = System.Configuration.ConfigurationManager.AppSettings["GeneratedDocuments"];

if (HttpContext.Current != null)

{

filePath = HttpContext.Current.Server.MapPath(filePath);

}

string fileName = null;

Mutex fileMutex = null;

try

{

while (true)

{

fileName = doc.FileName + "_" + System.DateTime.Now.ToString("ddMMyyyyhhmmss") + doc.DocumentType.Name;

bool created;

fileMutex = new Mutex(true, fileName.Replace("\\", "_"), out created);

if (fileMutex != null && created)

{

if (!System.IO.File.Exists(filePath + fileName))

break;

fileMutex.ReleaseMutex();

}

System.Threading.Thread.Sleep(1000);

}

File.WriteAllBytes(filePath + fileName, doc.DocumentContent.Content);

Page page = HttpContext.Current.CurrentHandler as Page;

Telerik.Web.UI.RadAjaxManager ajaxMgr = Telerik.Web.UI.RadAjaxManager.GetCurrent(page);

Session["documentToStream"] = filePath + fileName;

if (ajaxMgr != null)

{

ajaxMgr.ResponseScripts.Add(String.Format("mediaList.openViewWindow('{0}'); return false;", doc.MimeType));

}

else

{

page.ClientScript.RegisterStartupScript(page.GetType(), "documentStream", String.Format("mediaList.openViewWindow('{0}'); return false;", doc.MimeType), true);

finally

How to maintain State without using ViewState in RadGrid

Hi

I have some serious performance issue in application due to over use of ViewState and Session. To maintain DataTable current state during postbacks, do we have any other possible way? Is binding possible without using NeedDataSource event.? How to keep the values during postbacks? If enable "EnableViewState=true" of RadGrid, can I get the DataSource values between postbacks?

Thanks in advance

Add new row on a button click outside the grid. Cant capture values from new row on ItemCommand

Hi All,

Re-using OnRowContextMenu client event

Hello,

I have a RadGrid instance that uses the OnRowContextMenu client event to show a pop-up menu. It works perfectly.

However, the right-click context menu behavior isn't always intuitive to my users - so I'd like to add a small drop-down image to each row (in a specific column). When the drop-down image is left-clicked, I would like the "OnRowContextMenu" behavior to be invoked.

How can I accomplish this task?

RadGrid Export with DNN 6.0

Hi, I'm testing an existing site on DNN 6.0 and I've got a problem with the export feature of radgrid. Works fine in DNN 5.6 but when I try it on DNN 6.0 the screen goes white during post back and never returns to the page. The file dialog opens up to save, open or cancel, but after you do anything the page with the radgrid stays white. If I refresh the page it works ok.

I'm using an external button to do the export and to get it work under DNN 5.6 I had to disable postback (see code below). If I remove that code the pdf output and the excel output show up inside the radgrid, but you can't save it.

Not sure how to tackle this?

Thanks, all help is appreciated.

Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(initializeRequestHandler);

function initializeRequestHandler(sender, args) {

if (args.get_postBackElement().id.indexOf("ExportPDFButton") != -1) {

args.set_cancel(true);

sender._form["__EVENTTARGET"].value = args.get_postBackElement().id.replace(/\_/g, "$");

sender._form["__EVENTARGUMENT"].value = "";

sender._form.submit();

return;

}

if (args.get_postBackElement().id.indexOf("ExportExcelButton") != -1) {

args.set_cancel(true);

sender._form["__EVENTTARGET"].value = args.get_postBackElement().id.replace(/\_/g, "$");

sender._form["__EVENTARGUMENT"].value = "";

sender._form.submit();

return;

}

GridItem read attribute from client

If we add a value to a RadComboBoxItem attribute, we can always read it from the client side by saying

var value = combo.get_selectedItem().get_attributes().getAttribute('MyAttribute');

Can we do something similar for grid? During the ItemDataBound, I want to add attribute to each DataItem and read it when a row is selected and deselected clientside.

Thanks.
