Application memory usage: suggestions needed

Hello,

users of my web site are occasionally experiencing the "HTTP Error 503".

This is likely caused by some memory usage issue, and is occurring since I started adding Telerik UI For ASP.NET Ajax components to some pages.

In particular I created a page which features a RadScheduler and a RadListbox, both with server-side database binding. This page is continuously used by some 10 - 15 users during the day.

The application is deployed as a VS Website (not VS Web Application project), so there is a part of code that gets compiled at run-time.

The hosting is a shared one, with 500 MB of memory available, and is used only by employees of a private company (let's say 30 users).

My question is the following:

is there any suggestion on the best way to include Telerik components in ASP.NET pages in order to minimize memory usage?

For example: would converting from Website Project to Web Application Project be effective in reducing memory usage? Or whatever...

Thanks

Regards

Mike

[Solved] Put all child rows in edit mode for selected parent row

I have a hierarchical radGrid where the user can expand a parent row and then click on a child row to edit it in-place. I would like to provide them with a button on the parent row that would put all the child rows (for that parent row) in edit mode at the same time so that they can edit them all and save them all with 1 click.

I have researched this and found lots of info on how to do this on the parent rows but found nothing on how to do it on the child rows.

The way it is constructed is that the parent rows are in a "RadGrid" and the child rows are in a "GridTableView". Maybe this is where my problem is.

So, I need to either figure out how to accomplish it with what I have or to get some detail on how to redesign the grid to be able to do it.

Thanks in advance for any help or advise!

Here is my grid:

User Control with event dynamic creation and ajaxifying it

I have a user control creates a control which includes a RadDateTimePicker. The datetimepicker has a SelectedDateChanged event that fires and runs the code accordingly. Since it is dynamically created, I need to dynamically add it to the RadAjaxManager that already exists. My current approach doesn't seem to work, and I get a full postback.

User Control

public partial class CategoryHolder : System.Web.UI.UserControl

{

public string _category;

public string _mptt;

public DateTime _startDate;

public DateTime _endDate;

public EventHandler startDateChanged;

public EventHandler endDateChanged;

public string Category

{

get

{

return _category;

}

set

{

_category = value;

}

public string MPTT

{

get

{

return _mptt;

}

set

{

_mptt = value;

}

public DateTime StartDate

{

get

{

return _startDate;

}

set

{

_startDate = value;

}

public DateTime EndDate

{

get

{

return _endDate;

}

set

{

_endDate = value;

}

protected void Page_Init(object sender, EventArgs e)

{

}

protected void Page_Load(object sender, EventArgs e)

{

Label lbl = new Label();

HiddenField hf = new HiddenField();

RadDateTimePicker start = new RadDateTimePicker();

RadDateTimePicker end = new RadDateTimePicker();

start.AutoPostBack = true;

start.SelectedDateChanged += new Telerik.Web.UI.Calendar.SelectedDateChangedEventHandler(start_SelectedDateChanged);

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

start.ID = MPTT + "StartControl";

start.DatePopupButton.Visible = false;

start.TimePopupButton.Visible = false;

end.AutoPostBack = true;

end.SelectedDateChanged += new Telerik.Web.UI.Calendar.SelectedDateChangedEventHandler(end_SelectedDateChanged);

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

end.ID = MPTT + "EndControl";

end.DatePopupButton.Visible = false;

end.TimePopupButton.Visible = false;

lbl.Text = Category;

hf.Value = MPTT;

start.SelectedDate = StartDate;

end.SelectedDate = EndDate;

this.Controls.Add(lbl);

this.Controls.Add(hf);

this.Controls.Add(start);

this.Controls.Add(end);

}

void start_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)

{

if (this.startDateChanged != null)

{

this.startDateChanged(this, e);

}

void end_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)

{

if (this.endDateChanged != null)

{

this.endDateChanged(this, e);

}

Test Page using control:

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="rsm" runat="server"></telerik:RadScriptManager>

<telerik:RadAjaxManager ID="ram" runat="server"></telerik:RadAjaxManager>

<div>

<asp:PlaceHolder ID="Placeholder" runat="server"></asp:PlaceHolder>

</div>

</form>

</body>

</html>

Test Page C#:

protected void Page_Load(object sender, EventArgs e)

{

CategoryHolder ch = new CategoryHolder();

ch.Category = "Test Category";

ch.MPTT = "dfdfdopfksdopfsdop";

ch.StartDate = DateTime.Today;

ch.EndDate = DateTime.Today.AddDays(5);

ch.startDateChanged += new EventHandler(startPicker_SelectedDateChanged);

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

RadAjaxLoadingPanel loadingPanel = new RadAjaxLoadingPanel();

Placeholder.Controls.Add(ch);

manager.AjaxSettings.AddAjaxSetting(ch, ch, loadingPanel);

manager.AjaxSettings.AddAjaxSetting(ch, Placeholder, loadingPanel);

}

void startPicker_SelectedDateChanged(object sender, EventArgs e)

{

//Yay it runs, but on a full postback

}

Bug with EmptyMessage?

Hi,

I'm trying to work out why my code isn't working with the "control_name.EmptyMessage = message" type command from server side code. It works when running in the initial page load but then on ajax calls it doesn't set the fields.

Also in Javascript the set_emptyMessage command doesn't seem to work on a similar basis...Interestingly I can use the set_text command to acheive the same goal.

Is there a known bug with the emptymessage commands or will I need to post some code?

Regards,

Jon

Why Is key value wronf when editing a radgrid record

I have the following setup in my RadGrid lines in bold contain my database table primary key named LinkAnalysisId

<telerik:GridBoundColumn DataField="LinkAnalysisName" HeaderText="LinkAnalysisName" SortExpression="LinkAnalysisName"
UniqueName="LinkAnalysisName" Display="False">

Other bound columns are not shown when I update a records and try to save I run this C# code

protected void RadGrid1_UpdateCommand(object sender, Web.UI.GridCommandEventArgs e)

{

var editableItem = ((GridEditableItem)e.Item);

var linkAnalysisId = (int)RadGrid1.MasterTableView.Items[0].GetDataKeyValue("LinkAnalysisId");

//retrive entity from the Db

var record = DbContext.LinkAnalysis.Where(n => n.LinkAnalysisId == linkAnalysisId).FirstOrDefault();

if (record != null)

{

//update entity's state

editableItem.UpdateValues(record);

try

{

//save chanages to Db

DbContext.SaveChanges();

}

catch (System.Exception)

{

ShowErrorMessage();

}

The save does not pass the try catch block I have done some trouble shooting and I have found the code

var linkAnalysisId = (int)RadGrid1.MasterTableView.Items[0].GetDataKeyValue("LinkAnalysisId");

which sets the linkAnalysis variable is not getting the correct ID number so it appears I have something wrong. In debug mode when I inspect the values in the var editableItem I am seeing the correct linkAnalysis ID number it is just the code above is not getting the right record what have I done wrong here?

Thanks

Read Value of CommandItemTemplate CheckBox

I have a RadGrid with the following CommandItemTemplate items

<asp:Button ID="Diagram" Text="Diagram" runat="server" OnClick="DiagramClicked"></asp:Button>
<asp:CheckBox ID="OrphanCheck" Text="Exclude Orphans" runat="server"/>

When the user clicks the Diagram button, using C# I want to read the value of the Checkbox and build the needed code based on the value of the check box. How can I get the value of that checkbox. I have searched for a solution but all I can find is dealing with a checkbox in a column or row.

Thanks
