After 20 postbaks in the same page it fails.

Hello!

I have a proyect where I have several pages using RadControls, some have more controls than others and different controls from one page to another, but there is something in common each time I reach PostBack 20 the page throws an error, telling me that the arguments array passed to Function.prototype.apply is too large. Why is this happening and is there any way to overcome it?

I´ll Appreciate any kind of help on this.

Grid / Web Mail Grid - Filter

I was looking at one of the demos - Web mail grid in the below url http://demos.telerik.com/aspnet-ajax/grid/examples/programming/webmailgrid/defaultcs.aspx

I wanted to implement the Search similar to the one provided in this demo using filter expression. In this demo, the enter key press functionality of txtSearch doesn't seem to work. The image btnSearch click works as expected. Appreciate if you can provide your inputs on this.

Set the cell color based on the template label value

Hi,

I am trying to set the color of each cell in the grid based on the value of the label contained inside of the item template.

Here is my grid markup:

In the code behind I am trying to do the following, though not much luck finding the right control:

protected void rgSchedule_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = e.Item as GridDataItem;

foreach (Control ctrl in item.Controls)

{

if (ctrl is Label)

{

Label lbl = (Label)ctrl;

switch (lbl.Text)

{

case "Red":

item.BackColor = System.Drawing.Color.Red;

break;

case "White":

item.BackColor = System.Drawing.Color.White;

break;

case "Green":

item.BackColor = System.Drawing.Color.Green;

break;

}

rgSchedule.Rebind();

}

Own controls in 1 column

Hi,

I would like to ask you if there is possible to create column in Grid where I would have several own controls.

In that column there will be 4 small icons, which will have changed visibility according to certain data in given row. Is there any example, how I can make it ?

And I also have one question regarding to checkbox... I need to have checkbox in the column but it won't be bounded to some data. It will be only checkbox which also will be displayed according to data in the row. Because for some rows I will need to hide it. Which column I should use for this one ?

In the attachement there is a screenshot of gridview I would like to achieve with RadGrid.

Sorry for bothering, but I tried to search the pages for the answer before posting it here... I am really lost...

Thanks for any help

Maximize Minimize restore behavior

In looking at the RadWindow examples (the Restriction Zone example best fits my scenario) If you follow the steps below:

1. Maximize a window
2. Minimize the same window
3. Restore the window

In the operating system if you do this the window is restored to a maximized state. however, the radwindow restores to a non-maximized state. Is there a way to allow the radwindow to behave closer to the OS? (restoring the window to its last know state)

Thanks....

Problem with RadScheduler, WebService & Session State

I have a problem with webservice binding of RadScheduler on an ASP.NET forms application. I need to be able to access Session state from my webservice code, and sometimes it works and sometimes it doesn't.

Specifically the client event OnClientResourcesPopulating does not maintain session state - I presume because it's not passing the current session state cookie to the webservice call.

I have set up a sample project showing the problem, which I set up using the example here: http://www.telerik.com/help/aspnet-ajax/scheduler-webservicebinding.html

The key parts are that in my Default.aspx I set a session variable like this:

namespace RSWSTest

{

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

Session["TestSessionValue"] = "MyTestValue";

}

The page has a RadScheduler on it, configured to call a webservice. Here's a snippet from the webservice code:

[WebMethod(EnableSession=true)]

public IEnumerable<ResourceData> GetResources(SchedulerInfo schedulerInfo)

{

object v = Session["TestSessionValue"]; //-- THIS RETURNS NULL

Session["WS_GetResourcesCalled"] = true; //-- THIS WORKS BUT NOT VISIBLE IN SUBSEQUENT CALLS

return Controller.GetResources(schedulerInfo);

}

[WebMethod(EnableSession=true)]

public IEnumerable<AppointmentData> GetAppointments(SchedulerInfo schedulerInfo)

{

object v = Session["TestSessionValue"]; //-- THIS RETURNS "MyTestValue"

Session["WS_GetAppointmentsCalled"] = true;

return Controller.GetAppointments(schedulerInfo);

}

As you can see from my comments - it appears that the GetResources function starts a new session every time it is called, whilst the GetAppointments function seems to work as expected.

I need to find a solution to this as I have session-based user security and I want to return different things based on which user is stored in the current session.

I can't attach my test solution because it'll only let me post image files - but I can email it to someone if it would help - it's only 19k zipped!

Error in RadGrid when using RadDatePicker and KeyboardNavigation

Hello,
I have created a RadGrid that uses KeyboardNavigation for making changes. Two of my columns are dates and use RadDatePickers for inline editing. My third column is just a Notes column (text box).
When I hit [Enter] to put a row into Edit Mode, move to the Notes text box and hit [Enter] I can save the row, or if I hit [Escape] I can cancel the edit.

If, however, my focus is on one of the two RadDatePickers and I hit [Enter] or [Escape] I get the following error:

Text property cannot be set. String was not recognized as a valid DateTime.
[InvalidCastException: Text property cannot be set. String was not recognized as a valid DateTime.]
