VS 2012 crash after 2012 Q3 upgrade on Windows 8 (also on Windows 7 and VS 2010)

Computer: Windows 8, 64-bit, 8GB RAM

I upgraded my DevCraft 2012 Q2 SP2 installation to Q3 today and and VS 2012 is crashing after opening a solution. I have the following components installed:

RadControls for WinForms
RadControls for ASP.NET AJAX
RadControls for WPF
RadControls for Silverlight
KendoUI for ASP.NET MVC
MVC UI Extensions
Reporting
JustTrace
OpenAccess
JustMock

After installing, I started VS 2012 and took a very long time (perhaps 20 minutes) to get to a responsive state. I watched it in Task Manager and it looks like one core was pegged at 100% during this time and RAM consumed grew to over 500MB.

VS did come back eventually and I loaded a solution. Everything looked for a few seconds and then visual studio crashed. I tried rebooting and restarting VS but it crashes every time I try to load a solution. I went into the Windows EventLog and found this error:

Application: devenv.exe

at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr, Int32, IntPtr, IntPtr)

I then restarted VS and instead of loading a solution, I tried running TELERIK\VS Extensions Options... This also failed with a dialog complaining about a missing resource (see the attached image).

I also installed the update on a Windows 7 64-bit machine with both VS 2010 and 2012 installed. VS 2010 did not have the excessively long startup time but it also crashed when I tried loading a solution. VS 2012 seems to be stuck loading a solution right now.

Looks like something is wrong with Kendo. I'm going to try uninstalling it.

While uninstalling all of the Kendo components on my Windows 8/VS2012 machine, I went over to the Windows 7 machine, launched VS 2012 and opened the Telerik\VS Extensions Options... I didn't get an error message this time but the dialog is messed up. See the attached image.

Update: After uninstalling all of the Kendo components on the Windows 8/VS 2012 machine, VS2012 was able to load a solution and work normally. On the Windows 7/VS2010 machine, I'm now seeing VS2010 crash whild loading a solition.

GridButtonColumn CommandName Delete

It must be very simple but I can't work it out
I've got a grid

<telerik:RadGrid ID="RadGrid1"

runat="server"

ShowHeader="False"

AutoGenerateColumns="False"

>

<MasterTableView

DataKeyNames="AppID, IDCart, IDOrder">

<Columns>

..............

<telerik:GridTemplateColumn UniqueName="TemplateColumn" >

<HeaderStyle Width="335px" />

<ItemTemplate>

<asp:Literal ID="myLiteral" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"

UniqueName="DeleteColumn">

<HeaderStyle Width="15px" />

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

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

(myliteral is filled on temDataBound event.)
I bind the grid on code behind needdatasource event. It works fine.
If I click the GridButton to delete, raising RadGrid1_DeleteCommand event, it performs the delete function. It works fine

Now I just need to add Ajax to this.
so

<telerik:RadAjaxManager ID="RadAjaxManagerCart" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

<telerik:AjaxUpdatedControl ControlID="myLiteral" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

It is not working. The RadGrid1_DeleteCommand event is performed, but it does not refresh the grid

Could you help me please?

How to access RadGrid updated item

I've been searching your forums and reading documentation for several days now but have been unable to figure out how to access an updated item in my RadGrid.

Basically, I have a RadGrid with a Client Event where OnCommand is set to "RaiseCommand".

In my JavaScript RaiseCommand function, I am able to determine the command that was raised. When the command raised is "Update" I am calling ValidateInput function, passing along the sender and eventArgs that was passed to the RaiseCommand function.

Inside ValidateInput, I need to access updated values and do some edits to ensure the new values meet specific requirements. However I have been unable to figure out how to access the new values.

So I thought I'd try accessing the new values in my codebehind. I thought that if I could figure out how to do it there, I could use the same method in my javascript. I created subroutines that handle EditCommand, and UpdateCommand.

Inside my subroutine for EditCommand, I have been able to find and display in a message box, the values in the row where Edit was clicked.

When I execute my web page, after clicking Edit on a row in my RadGrid, I then modify the contents of one of the four fields. I then click on Update and my subroutine for UpdateCommand is invoked. Inside this subroutine, I have been able to succesfully find and display the SavedOldValues. However, I am unable to find the new value that I entered into one of the fields.

Here's some of my code:

<telerik:RadGrid ID="rgUsers" runat="server" BorderWidth="1" BorderColor ="#EBAB00" AutoGenerateColumns="false" AllowSorting="true" >

<ClientSettings>

<ClientEvents OnCommand="RaiseCommand" />

</ClientSettings>

<ItemStyle Font-Size="10pt" Font-Names="Sans-serif" />

<HeaderStyle Font-Size="12pt" Font-Names="Sans-serif" />

<MasterTableView EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn UniqueName="UserId" DataField="UserId"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="username" DataField="username"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="level" DataField="level"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="subcatid" DataField="subcatid"></telerik:GridBoundColumn>

<telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>

<telerik:GridClientDeleteColumn ConfirmText="Are you sure you want to delete this user?></telerik:GridClientDeleteColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Private Sub rgUsers_EditCommand(ByVal sender As Object, ByVal e As

Telerik.Web.UI.GridCommandEventArgs) Handles rgUsers.EditCommand

Dim gdi As GridDataItem = CType(e.Item, GridDataItem)

Dim UserId As String

Dim UserName As String

Dim Level As Integer

Dim SubCategoryID As Integer

UserId = gdi.Item("UserId").Text

UserName = gdi.Item("username").Text

Level = CType(gdi.Item("level").Text, Integer)

SubCategoryID = CType(gdi.Item("subcatid").Text, Integer)

MsgBox("EditCommand on " & UserId & " " & UserName & " " & Level.ToString & " " & SubCategoryID.ToString)

End Sub

Private Sub rgUsers_UpdateCommand(ByVal sender As Object, ByVal e As

Telerik.Web.UI.GridCommandEventArgs) Handles rgUsers.UpdateCommand

Dim rg As RadGrid = CType(sender, RadGrid)

Dim gdie As GridDataItem = CType(e.Item, GridDataItem)

Dim UpdatedRow As Integer = gdie.ItemIndex

Dim MasterTable As GridTableView = rg.MasterTableView

Dim gdim As GridDataItem = MasterTable.Items(UpdatedRow)

Dim cell As TableCell

Dim i As Integer

MsgBox(gdim.SavedOldValues("UserId").ToString)

MsgBox(gdim.SavedOldValues("username").ToString)

MsgBox(gdim.SavedOldValues("level").ToString)

MsgBox(gdim.SavedOldValues("subcatid").ToString)

i = 0

For Each cell In gdie.Cells

MsgBox(i.ToString & " " & cell.Text)

i += 1

Next

i = 0

For Each cell In gdim.Cells

MsgBox(i.ToString & " " & cell.Text)

i += 1

Next

End Sub

After I click on Update, my UpdateCommand handler fires, and I see message boxes containing the four saved old values. But the following messages boxes (2 sets of 8) all display &nbsp.

I know there must something fundamental that I'm missing, but for the life of me, I've been unable to figure it out.

Please tell me how I can access the updated values in my codebehind, and then also in javascript.

Thanks!

PDF Export in Landscape

Is there a way to export the scheduler into a landscape mode so it fits the entire PDF width? I tried setting the PDF PageHeight and PageWidth to be in landscape, but it ended up only filling half the page width. If I'm missing something, please let me know.

Here is a link to a screenshot of what I got.

Possible To Offset Axis Labels?

Hello,

I'm working with the asp.net RadChart, trying to more finely tune the displayed labels associated with a chart.

Specifically, I'd like to start the axis labels and ticks at a point not at the start of the data, or at 0. In the attached files, I have my current chart's axis (with RadChart) where the labels start at the minValue and end with the maxValue of the Axis.

Target.png represents what I'd like to see in the chart, with the label starting at a pre-defined point in the data. In this case, I'd like to start my labeling at July 1, 2010 instead of April 28, 2010 in the dataset.

Is there an easy way to do this?

Thanks,
Alex Bucevicius

Change Maxlength Clientside

I need to change the maxlength clientside in a RadTextBox depending on a selection in a combobox. I tried this:

var txt = $find("<%= txtValue.ClientID %>");

var item = eventArgs.get_item();

var value = item.get_value();

switch(value)

{

case "CUST_NU":

txt.MaxLength = 8;

break;

case "NAME":

txt.MaxLength = 30;

break;

case "CIC":

txt.MaxLength = 4;

break;

case "INVOICE_NU":

txt.MaxLength = 10;

break;

}

Then checked for the maxlength via alert(txt.MaxLength) and it shows the new maxlength value but the textbox still doesn't change to the new length.

Client side firstDayStart() not working with webservice

onclientRequestSuccess does not seem to have the updated firstDayStart(). I thought I had figured it out, but its not working:

As I navigate in the calendar, changing months, it does not reflect the right day - what am I doing wrong?

function onClientRequestSuccess(scheduler, eventArgs) {

if (typeof loadList == 'function') {

var start = scheduler.get_firstDayStart();

var end = start;

var curView = scheduler.get_selectedView();

if (curView == 0) { // day view

end.setHours(start.getHours() + 24);

} else if (curView == 1) { // week view

end.setHours(start.getHours() + (24 * 7));

} else if (curView == 2) { // week view

end.setMonth(start.getMonth() + 1);

// need to find out if we are on a Saturday.. If not, we need to add days until we get there

}

alert(start + " **- " + end);

loadList(start.getTime(), end);

}

button in a radgrid that doesnt make a request in jquery

Hi All,

I created a button in a radgrid with below code. When I try to reach the value in columns that is okay. I can make it.

But I try to make a request with these parameters on my web service. I get this error "property of value is null or undefined" at runtime.

Now I am thinking I create these buttons dynamically. Is that the reason I cant make a request?

Please help.

protected void rgGeneralSearch_ItemDataBound(object sender, GridItemEventArgs e) {  if (e.Item is

GridDataItem)<br>            {<br>                GridDataItem gridDataItem = (GridDataItem)e.Item;<br>                Button btnAdd =<br>                    (Button)gridDataItem[

"Add"].FindControl("btnAdd"

);<br>                RadNumericTextBox txtQuantity =<br>                    (RadNumericTextBox)gridDataItem[

"Quantity"].FindControl("txtQuantity"); 

//btnAdd.Attributes["onclick"] = "btnAddClick('" + txtQuantity.ClientID + ", "+ rgGeneralSearch.MasterTableView.GetColumn("Code") + "')";<br>                btnAdd.Attributes["onclick"] = "btnAddClick('" + txtQuantity.ClientID + "', '"+ e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Code"] +"')";<br>                //btnAdd.Attributes["href"] = "#";<br>                btnAdd.Attributes.Add("ajax", "");<br>            }<br>        }

function btnAddClick(Quantity, Code) { alert($get(Quantity).value); alert(Code);  var SenderType = 1;  var SenderId = 22;  var ProductId = 333;  var CustomerId = 99;  var SalesmanId = 88;  var DiscSpecial = 23;  var TerminalNumber = 234;  var webMethod = "http://localhost:5261/WS/Basket_WS.asmx/InsertBasket";  var parameters = "{'SenderType':'" + SenderType + "', 'SenderId':'" + SenderId + "', 'ProductId':'" + ProductId + "', 'CustomerId':'" + CustomerId + "', 'SalesmanId':'" + SalesmanId + "', 'Quantity':'" + 22 + "','DiscSpecial':'" + DiscSpecial + "','TerminalNumber':'" + TerminalNumber + "'}"; $.ajax({ type: "GET", url: webMethod, data: parameters, contentType: "application/json; charset=utf-8", dataType: "json", success: OnGetSuccess, error: OnGetError }); }
