Help implementing ScheduleGeneral using LINQ (or SQL)

Hello!

Guys, I need help using your scheduling control as I'm finding myself in a troubled scenario. I'm attaching a cut-down version of my database.

I require a schedule in the form of an organizer. Required design concept excel and image attached.

Some facts:

Every Locum can have a maximum of two Jobs in a single day. So the maximum items (jobs) available per day is two.

I hope you guys can help me out.

Unable to serialize session state

I need to use StateServer mode for session state in my application, but doing so returns the error: "Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode."

I'm using the .cs example code from \Telerik\RadControls for ASP.NET AJAX Q2 2010\Live Demos\Grid\Examples\Programming\DragAndDrop folder. Is there any way to get this code to work using StateServer sessionState mode rather than InProc mode?

Get filtered records

Hi Telerik,

Am using radgrid with filter enabled. Is there any way in radgrid to access the filtered result set before it binds to the Grid. Or any event which is fired before the filtered data is bound to the Grid? Please give me a solution for this as soon as possible.

Thanks
Priya

Upgrading RadControls version from ASPNET to ASPNET AJAX

Hi There,

we recently decided to begin the process of upgrading our product so that it becomes compatible with Telerik RadControls ASP.NET AJAX. We've spent a number of days now reading different KB articles and watching some upgrade videos but have been running into the same problems regardless. Our product is a .NET 2.0 application with no prior use of AJAX, so we also had to look into editing the web.config so that it supports System.Web.Extensions.

There have been two errors that visual studio constantly prompts us about once we go through the process of replacing the register directive with 'Telerik.Web.UI' and then deleting the older DLLs. (We are also receiving errors for Telerik.Charting but this is another story i think...)

ASP.NET runtime error: The base class includes the field 'radGdUserGroup', but its type (Telerik.WebControls.RadGrid) is not compatible with the type of control (Telerik.Web.UI.RadGrid). <<FILENAME>>

ASP.NET runtime error: Could not load file or assembly 'RadTreeView.Net2' or one of its dependencies. The system cannot find the file specified. <<FILENAME>>

We really hope that you guys can assist in helping to remove these errors from our solution so that we can continue using the Telerik suite.

Regards

A.

Time issue – Grid EditMode

Hello all,

I have a form which has 7 grids, one grid per weekday.

For each grid I dynamically create a datatable because the column layout can change.

I use a HeaderTemplate because I need to merge headers, an ItemTemplate and an EditTemplate.

The form is displayed correctly, however I’d like all rows to be directly in EditMode, which I set in the PreRender event.

When I then trigger the Rebind event, it takes endlessly (up to 40 seconds) until the form is displayed. If I disable the EditMode, it’s displayed right away. (See attached pictures)

Any help would be appreciated.

Custom GridColumnEditor

Hi,

I have created a custom GridColumnEditor that extends GridTextColumnEditor. My custom editor holds a composite control (consisting of a textbox and some other controls) that is used for editing the value. The composite controls shows up with the correct value when I press the edit button, but I have problems extracting the new value when I press the save button, I always get the old value.

I use the following for extracting the new value: (EditItem.Value (which is the textbox value) always has the old value)



List<UIPhaseItem> items = new List<UIPhaseItem>();



foreach

(GridColumn column in e.Item.OwnerTableView.RenderColumns)

{

if (column is IGridEditableColumn)

{

IGridEditableColumn editableCol = (column as IGridEditableColumn);

if (editableCol.IsEditable)

{

IGridColumnEditor editor = editManager.GetColumnEditor(editableCol);

if (editor is CustomColumnEditor)

{

items.Add(((CustomColumnEditor)editor).EditItem);

}

Any ideas?

Below is my custom column editor.

public class CustomColumnEditor : GridTextBoxColumnEditor

{

Public UIPhaseItem EditItem { get; set;}

public CustomColumnEditor(UIPhaseItem item, long id)

{

this.EditItem = item;

this.EditItem.Enabled = true;

this.EditItem.Visible = true;

this.EditItem.ID = id.ToString();

}

protected override void AddControlsToContainer()

{

this.ContainerControl.Controls.Add(EditItem);

}

protected override void LoadControlsFromContainer()

{

this.EditItem = (UIPhaseItem)this.ContainerControl.Controls[0];

}

Restrict page in RadWindow

I use client function "radopen" to open RadWindow and show one page in it.

Scenario: RadWindow is closed, main page is showed. After a while the session expires and, not knowing that, I open RadWindow and it show login page inside (!!!) which is completely wrong and inappropriate to me.

Can RadWindow somehow be limited to display only the page I told him, and if he can not, to close? Login page is not intended there to be loaded!
