I have a page with a grid and a RadWindowManager with some windows.

Inside these window I have some other controls which I use to interact with the grid.

Now I add a button somewhere in my page:

<telerik:RadButton runat="server" ID="RadButton1" AutoPostBack="true" OnClick="btnAjouter_Click">

</telerik:RadButton>

But for some reason, when I click on this button nothing happen. There is no postback and no javascript error.

I tried to put a UserControl that I use in a RadWindow in comment and the button seems to work...

My UserControl looks like this:

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="WindowDivergence.ascx.vb"

Inherits="GESPHARxLite_2.WindowDivergence" %>

<%@ Import Namespace="GESPHARxLite_2.GestionMessages" %>

I can't find why my button only works when I put my UserControl in comment.

Thanks.

[Solved] ASP.NET AJAX Q3 2012 Crashing my VS 2010

I took the update to the ASP.NET AJAX controls this morning when prompted in VS 2010. After the install no projects will open. Winforms or Websites. Visual Studio Encounters and error and shuts down when trying to open a project. I re-installed VS 2010 and no luck. I ended up having to uninstall AJAX and was able to continue working on my Winform apps but now I have no controls for my asp.net web apps. This is a disaster. I can't find the installs for the previous version that was running for Q2 2012.

Radgrid rebind does not update filter template controls

Hi,
I have a radgrid that has custom filter template that consists of distinct checkboxes based on the current data. also, I have a linkbutton column that opens up a new window to edit the row. the issue im having is after a row has been edited the filter control data is not update after i call rebind.

sample grid:
lets says here's how the grid looks like when it loads

col1                          col2
no filter                     filter checkboxes(abc company, def company, ghi company)
edit button                abc company
edit button                def company
edit button                ghi company

then lets say u edit "abc company" to "xyz company"
then do RadGrid1.ReBind()

the "abc company" updates the gridrow perfectly to "xyz company" but the problem is the filter checkboxes remains ("abc company"..)

is there any other way to "rebind" the entire radgrid including the filter controls?

Thanks much!

Multicolumn combo on clientside webservice call

i am trying to get a multicolumn combo to populate but cannot get it to display correctly

the combo is as follows:-

<telerik:RadComboBox ID="comboBoxBoard" runat="server" Filter="Contains" EmptyMessage="Boarding at"

{

int itemsCount;

int.TryParse(numberOfItems, out itemsCount);

int itemOffset = itemsCount;

int endOffset = Math.Min(itemOffset + ITEMS_PER_REQUEST, dtBoarding.Rows.Count);

comboData.EndOfItems = endOffset == dtBoarding.Rows.Count;

List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(endOffset - itemOffset);

foreach (DataRow dataRow in dtBoarding.Rows)

{

RadComboBoxItemData itemData = new RadComboBoxItemData();

string stopNumber = dataRow["StopNumber"].ToString();

string address = dataRow["Address"].ToString();

string location = dataRow["Location"].ToString();

string stage = (dataRow["StageNumber"].ToString() != string.Empty ? dataRow["StageNumber"].ToString() : "");

itemData.Value = stopNumber;

itemData.Text = stopNumber;

itemData.Attributes.Add("Address", address);

itemData.Attributes.Add("Location", location);

itemData.Attributes.Add("Stage", stage);

result.Add(itemData);

}

comboData.Message = GetStatusMessage(endOffset, dtBoarding.Rows.Count);

comboData.Items = result.ToArray();

}

if (comboData.Items == null)

comboData.Items = new RadComboBoxItemData[0];

return comboData;

}

catch (Exception ex)

{

return null;

}

running an old version of the controls:- v2.0.50727

Any help is greatly appreciated

Cheers,

Update with class.

I need to check for customer pricing and or volume pricing before updating grid. Why does this not work?

protected void RadCartGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
{
GridEditableItem editedItem = e.Item as GridEditableItem;

string itemNumber = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Itemnumber"].ToString();
int lineID = Convert.ToInt32(editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["LineID"].ToString());
string custNum = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["CustomerNumber"].ToString();
int qty = Convert.ToInt32(editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Quantity"].ToString());

//CHECK FOR CUSTOMER PRICING OR QTY BREAK PRICING.
updateCart.UPDateItem(itemNumber, lineID, custNum, qty);
RadCartGrid1.Rebind();
}

Load stylesheet after stylesheetmanager

HI
I use stylesheetmanager to load my styles
but now I need to change the logo for my server side events
so I put this on pageload

If Not Session("folderStyle") = Nothing Then

Dim link As New HtmlLink()

link.Href = Session("folderStyle")

link.Attributes.Add("rel", "stylesheet")

link.Attributes.Add("type", "text/css")

Page.Header.Controls.Add(link)

End If

So when I load the new styel I overwrite the definitions in the common stylessheetmanager references
--
the problem is that Stylesheetmanager load the styles at the last row of html before </head>tag
so the result is

<link href="/css/ProdottiManzi/English/stile.css" rel="stylesheet" type="text/css" />

<link href=

"/Telerik.Web.UI.WebResource.axd?compress=1&_TSM_CombinedScripts_=%3b%3b%7c634859195287498065%3a94dbb91c%3a58260d52%3a267fe04e%3bTelerik.Web.UI%2c+Version%3d2012.2.912.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ait-IT%3a6aabe639-e731-432d-8e00-1a2e36f6eee0%3aed2942d4%3a53e1db5a%3ad126a8ef%3a92753c09%3a91f742eb%3a4f5793d0%3afe53831e%3bTelerik.Web.UI.Skins%2c+Version%3d2012.2.912.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ait-IT%3ab0377b55-749e-4497-8000-b9ed5bce0744%3a6856648a%3af7a27b73%3a261be263"

type="text/css" rel="stylesheet" /><title>

</title></head>

and as you can see my definition is before and not after
telerik sheets and mine used in stylesheetmanager

is there some property to change or my I add a style reference at runtime ?
thanks

[Solved] Dynamically created TabStrip losing PageView on postback

I have a dynamically added usercontrol that dynamically creates a TabStrip and associated PageViews from a database. For SEO purposes what I want this to do is create the PageViews for some of the tabs initially but also have some of the Tabs that will dynamically add thier PageViews on TabClick. Some of these also get additional user controls added to the PageView.

The problem is that the tabs with PageViews work fine until I click one that loads another page OnPostBack. Once the new PageView is dynamacally added OnPostBack I loose all of the ones that were originally created.

I believe I need to use the multipage PageViewCreated event to persist the dynamically created controls inside a RadPageView such as what is shown on this demo http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx.

My problem is I am adding the content to the initially created PageViews by placing it into a Literal using Controls.Add which works fine initially. The problem is I can't seem to find it using e.PageView.FindControl to persit it in the PageViewCreated event below which always shows "PageView not found" in the code below.

Any help would be greatly appreciated!

Thanks in advance,
Dave

Identifying when a user saves without changes

When a user modifies a schedule is there a way to detect on the server if the appointment and the modified appointment are the same, in other words, there are no changes? Or client side is there a way to simply call the cancel submit when save is clicked with no changes?

I cannot find any way to do a compare on the appointment and the modified appointment that is built in and would cover all information passed from the form.

Thanks!
