Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: Rebind.

Error : Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: Rebind.

In one of our project requirement we have customized the SPRADGRID webpart and have created our own webpart. We are facing some issues with Ajax request.

The rad grid is bound to an SharePoint list. and we are calling the ShowEditInsertForm to open the Edit And Add form for the list. when we submit the form. We are trying to refresh the grid through ajax request when the model pop is closed. we get the above mentioned error when the ajax request completes its execution.

below is some part from the code.

Ajax Manager ajax request code
void AjaxManager_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
if (e.Argument == "Rebind")
{
this.Grid.Rebind();
}
}

JavaScript Code to raise the request
function refreshGrid(arg)
{
if (!arg)
{
ajaxManagerClientId = 'ctl00_RadAjaxManager1';
$find(ajaxManagerClientId).ajaxRequest();
}
else
{
ajaxManagerClientId = 'ctl00_RadAjaxManager1';
$find(ajaxManagerClientId).ajaxRequest();
}
}

using RadAJAX Manager with RadComboBox Or DropDownList

Hello ,,

I've two RadComboBox one for the Region and the other for the Place,,

    
                            <telerik:RadComboBox ID="ddl_Regions" runat="server" Skin="WebBlue" Filter="Contains" 
        
                                Width="200px" AutoPostBack="True" CssClass="Lists">  
        
                            </telerik:RadComboBox> 
        
                            <telerik:RadComboBox ID="ddl_Places" runat="server" Skin="WebBlue" Filter="Contains" 
        
                                Width="200px" CssClass="Lists">  
        
                            </telerik:RadComboBox>

When the user choose a Region the Place list will rebind and get the Places of the selected Region

    
                                Dim Places As New BusinessLayer.Placess  
        
                                Places.GetByRegionID(ddl_Regions.SelectedValue)  
        
                                ddl_Places.DataSource = Places  
        
                                ddl_Places.DataTextField = "Name" 
        
                                ddl_Places.DataValueField = "ID" 
        
                                ddl_Places.DataBind()

everything was fine until i put the Region

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="ddl_Regions" /> 
        
                            <telerik:AjaxUpdatedControl ControlID="ddl_Places" /> 
        
                            <telerik:AjaxUpdatedControl ControlID="lbl_result" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager>

when I did that the application still enter the selectedIndexChanged Event of the ddl_Regions and rebind the places but the ddl_Places does't refresh until i did a postback

Should i do postback everytime i want to rebind the ddl_Places data ,?,, what's the best way to achieve this?

Thank for help

Tabs Based on Date Passed in QueryString

I'm interested in building a tab strip that will dynamically change based on a value passed in a querystring, such as a date.
The current date will be highlighted in the tab and multiple days on either side of the center tab will show.
I've attached a screen shot of what I'd like to do and I didn't know if there's a similar example out there.

Thanks,
Matt

RadComboBox ajax client side encoding

Im facing a problem with encoding of RadComboBox.

Before postback in Viewstate I have:

ctl00_plhBody_ctrRegistration_cbBoss_ClientState:{"logEntries":[],"value":"20","text":"Андреев","enabled":true}

And after postback there is:

{"logEntries":[],"value":"20","text":"Андреев","enabled":true}<br>

And then application crashes. Its in updatePanel, and unfortunately I dont have error message (its on productioin right now and Ive got limited access to logs).

Thanks for any suggestions

RadButtons Moving on MouseOver

I'm using two RadButtons skinned with Windows7 skin in a .Net 3.5 ASP.Net web application. Here's the relevant markup:

<asp:Panel ID="pnlCancelRequestConfirmation" runat="server" style="display: none;" CssClass="CancelRequestModalPopUp">

<div style="background-color: White; border: 2 solid black; padding: 10px;">

Enter the reason for removing this SRF:<br />

<asp:TextBox ID="txtCancelReason" runat="server" Width="200px"></asp:TextBox>

<br />

<asp:RequiredFieldValidator ID="rfvCancelReason" runat="server" ValidationGroup="CancelRequestConfirmationGroup"

ControlToValidate="txtCancelReason" ErrorMessage="Reason is required" CssClass="SrfRedText"

Display="Dynamic" />

<br />

<div style="text-align: right;">

<telerik:RadButton ID="btnCancelSrfCancelRequest" runat="server" Text="Remove SRF" OnClick="btnCancelSrfCancelRequest_Click" CausesValidation="true" ValidationGroup="CancelRequestConfirmationGroup"></telerik:RadButton>

<telerik:RadButton ID="btnCloseSrfCancelRequest" runat="server" Text="Cancel" CausesValidation="false"></telerik:RadButton>

</div>

<br />

<div style="text-align: right;">

<asp:Button ID="btnTest" runat="server" Text="ASP.Net Button" />

</div>

</asp:Panel>

This code is being displayed in an Ajax Toolkit Modal Popup. But this happens elsewhere in my code as well. I think I've isolated it to some jQuery behavior but I'm not sure how to prevent it. If I use a normal ASP.Net button, I don't get this behavior.

When I tab out of the textbox above the buttons, the buttons shift to the left. When I mouse over them, they reposition back to where they are supposed to be.

Here's a screencast to show what I'm talking about:

http://screencast.com/t/sM21Z1WPZZ

Has anyone experieced this problem? If so, what should I do to fix it?

Thanks.

Rad Window State Issue

Hi,

I have a requirement where I need to have a master page and a RAD menu control on the master page. Now I need a new RAD window on click of any menu item from server side irrespective of the fact whether I am clicking same menu item or any other menu item.

I am creating a new RAD window on click event of every menu item click event from server side code and able to successfully create a new RAD window when I am clicking first time on any menu item. But whenever I clicked on any other menu item or same menu item again, my previously opened RAD window get lost and new rad window appears. I think it is a state issue, seems like page is not able to maintain RAD windows on the post back.

I have also tried creating RAD windows from client side java script as well. I am able to create multiple rad windows using java script on click of any of my menu item but all RAD windows created with java script are getting lost on click of browser’s refresh button and F5 button.

Please let me know the best way to create multiple RAD windows from server side and client side as well along with state management. Please help me out to maintain rad windows even after post back of page where these windows exist.

InsertCommand not triggered

Hi all:
I must be doing something wrong in the settings as I can't seem to figure out why my listbox isn't auto updating. I've used this demo to help me on my way, and I successfully have the delete statement working great. I need to get the "insert" to work. Here's my code:

.aspx

pasleadSelected_DS.DeleteParameters("u").DefaultValue = pasuser

pasleadSelected_DS.InsertParameters("aid").DefaultValue = aid

pasleadSelected_DS.InsertParameters("u").DefaultValue = pasuser

The action I need to track automatically, is when the user moves an item from paslead_rlb to paslead_rlbDestination. Help! Thanks!

Problem with Grid Header

I am having a problem with the header portion of the radgrid.

When the page is first displayed the right-hand portion of the header has been eliminated and replaced with white space. Attached graphic "HeaderWidth1.png" shows this and also shows the Developer Tools display with the header segment highlighted. You can see the width is set at "663px".

If I change the "663px" to "100%", the header will be displayed at full width (refer to attached graphic "HeaderWidth2.png").

I have tried coding a special css class for this item setting its width to 100% to no avail.

The code for the .aspx file is displayed immediately below. Can anyone tell me why this issue is happening and how I can eliminate it?

Thanks in advance!

Problem with Radgrid nestedview template

Hi,

   I am having a problem with RadGrid control. I am using radgrid with filter and sorting option. Now my grid is having 2 rows for a particular record (as shown in lookup2.png). In the starting when we come onto the page it looks like a general grid with filter option on the top. But when we select edit in dropdownlist present in action column. then that row comes down and another edit record row become visible with prepopuleted fields. now when i click on update, It updates the record in database and edit row becomes invisible.
I tried to solve this my using nestedviewtemplate example given in the forum but i did not get it.
   So can u make a dummy application give it to me because this concept is the main concept of the project and nearly 80% grids of the project is based on this concept.
  So please resolve it asap.

With Regards

ContentArea background color

Ive read multiple threads on here about setting the background color of the editor but with no success.

As my page background is dark, text is unreadable so i want to make the background white.

Ive created a EditorContentArea.css file but not sure where i place this. Its currently in the web root but isnt being picked up.

do i need to set the path to this somewhere in an editor property or does the editor expect to load it from a certain location?

has anyone succeeded in doing this?

my only alternative is to try another editor if i can't find a solution to this
