RadFilter with grid throw error of "Sys.WebForms.PageRequestManagerServerErrorException"

I use RadFilter on radgrid, everything worked just fine for a while, but after I added more features to the grid (show/hide column, exporting), all the sudden the filter stop working and throw error on "Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.", after search I guess it might have something to do with exporting, I use external button for word exporting, but i am not using filter in the grid, I use RadFilter associate with the radgrid...any ideas?

Thanks,

Shan

IE7 postback issue

Good afternoon folks,
I have in my aspx page a form where user fill out all necessary information to sent email.The form contains numerious numbers of Telerik controls.
I have RadComboBox with autopostback = true(this is in the middle of the form).When user select from ComboBox 'Yes' or 'No' it fire event:

protected

void ddlAprv_SelectedIndexChanged1(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

RadPanelBar attestPanel = (RadPanelBar)formPanel.FindItemByValue("principalForm").FindControl("attestationPanel");

RadNumericTextBox jobPostNo = (RadNumericTextBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("JobPostingNo");

RadComboBox ddlAprvPost = (RadComboBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("ddlAprv");

RadComboBox ddlpost = (RadComboBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("ddlPost");

if (ddlAprvPost.SelectedValue == "Y")

{

jobPostNo.Enabled =

true;

jobPostNo.Focus();

}

else

{

if (jobPostNo.Text.Length > 0)

{

jobPostNo.Text =

string.Empty;

}

jobPostNo.Enabled =

false;

ScriptManager1.SetFocus(ddlpost.ClientID +

"_Input");

}

Focus goes to the next Box and ask to put some numbers.This is working for IE8
But for IE7 focus is lost and form jump right to the top.

Please help me to resolve this issue.
Thanks

Prevent postback when minimizing/restoring a radwindow

Hi,

I have a RadWindowManager and open up RadWindows client-side through the manager control.
I'm not sure if I set a property wrong or what, but minimizing/restoring a radwindow causes the page inside the radwindow to postback.
Maximizing/restoring, moving, resizing the radwindow does not postback. Only minimize/restore causes a postback.

The only client event I have on the RadWindowManager is OnClientBeforeClose
This is the manager:

<telerik:RadWindowManager ID="RadWindowManagerParent" runat="server" Animation="None" OffsetElementID="wrapper"

MinimizeZoneID="DivMinimizeZone" RestrictionZoneID="TdContent" EnableTheming="true"

AnimationDuration="250" DestroyOnClose="true" EnableShadow="true" IconUrl="~/Images/Blue/Window_Icon.png"

PreserveClientState="true" ShowContentDuringLoad="false" ShowOnTopWhenMaximized="false"

Width="1000" Height="650" VisibleStatusbar="false" ReloadOnShow="true" KeepInScreenBounds="false"

Style="z-index: 2501;" Behaviors="Close,Maximize,Minimize,Move,Reload,Resize"

OnClientBeforeClose="RadWindowManagerParentOnClientBeforeClose">

<Windows>

</Windows>

</telerik:RadWindowManager>

Any ideas?

Thanks!!!

Multi Calendars Navigation by outside buttons

Hi All,

On my page, there are 3 Rad Calendars with MultiViewColumns="2" MultiViewRows="6". Above them there are 4 Rad buttons for navigation purpose ( 2 for backward & 2 for forward) . I want to navigate all 3 calendars by clicking on those 4 buttons. In buttons' click event, I am setting focusdate of each calendar but it doesn't work properly.

1) Is it possible to do this ?
2) If no, then, is it possible that by clicking on one RadCalendar's navigation button, for other 2 calendars navigation events also get fired?
3) Any other way around to do that.

Thanks,

Help on accomplish Facebook like feature

In Facebook, when composing an email, the user is shown a dropdown similar to the radComboBox Filtering feature. (see screenshot link below). When selected, the selected item has a blue wrapper with X to be able to delete a selected item easily. With the samples I've seen, you can't delete individual items. It seems that you have to start over especially if you want to delete the very first item you selected. Starting over is not ideal if you already selected a few. Any idea how to accomplish similar functionality?

screen shot

Any help would be appreciated.

Relationship Resource and Appointment

Hello,

How can I tell the component appointment scheduler which belong to a particular resource, my modeling database is one to many (a resource can have any or many an appointment and appointment may have no or a resourse), I saw that it is possible to do contrary an appointment that is easily have encore resources, so maybe in the future be useful for my implementation, but now what was that I needed to send the ID (KeyField) and ForeignKey with the ID value (the Resource KeyField) interpretation that he given resource belongs to the appointment with the ID equal to its ForeignKey, which saw far in the object properties not possible, only possible with the opposite meaning: to inform the resource and its keyField ForeignKeyField and it identifies all appointments with KeyField ForeignKeyField expressed in the same resource. it will not help in my case since each appointment will have a unique ID (UniqueKey) and thus will not be possible to assign more than one appointment for the same resource.

Note: I have tried to "circumvent" the component entering the appointment of the ForeignKey which is the Resource ID of the attribute KeyField Appointment, more logically it was supposed to work, more just not working, why the appointment KeyField attribute is used in various situations natively by the component, such as when you are asked to edit it keyField he uses to identify which appointment was required to issue, so bringing the wrong attributes.

I wonder if any have tried to do something about it, I'm looking at one week all the attributes of the component in search of a ForeignKey attribute to the appointment, so far nothing more that could help me. If anyone knows a way to thank me.

The Help here at Telerik have looked just about everything.

Note: How much English do not know Using Google Translate as an aid to write my doubts. Maybe not the best clarity. But I tried to review it

Thank you for your attention

Fernando.
