[Solved] telerik:RadPageView error inside Update Panel

We have telerik:RadMultiPage with 3 RadPageView control on a Visual Webpart in sharepoint site.

When this webpart is opened user enters few detail and then click on next button which will take then to next RADPageView .

But on Production server we are getting following error when user click on Next button

ScriptResource.axd?d=OuxNwVWHD89YhOJQ8KoflBg1KGlPeB5feLGISY35w5AR9riq5maPEdVKtJ3yHJoTRwy9UXHCxY_UZt…:5 Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '
<!DOCTYPE html PUB'.

We are not having this issue in dev or Test environment , We have tried checking Firewall setting to check if Ajax header information is gettgin trimmed but it is not .

Please let me know If there is anything we can try , or there is any known issue regrading this ?

Telerik ComboBox get_items().add(item) not binding value at server

As i'm binding value in client site for combobox like this way in Jquery.

$.each(response, function (index, value) {

let item = new Telerik.Web.UI.RadComboBoxItem();

item.set_text(value.EnggName);

item.set_value(value.EngineerId);

$find('<%= cmb_EnggList.ClientID%>').get_items().add(item);

});

and it binds the value correctly but when i post it in the server like this.

foreach (Telerik.Web.UI.RadComboBoxItem EngineerId in cmb_EnggList.Items)// it gives empty items

{

if (EngineerId.Checked)

{

Guid GuidEngineerId = new Guid(EngineerId.Value);

_JobCalendarEngg = new JobCalendarEngg();

_JobCalendarEngg.JobCalendarEnggId = Guid.NewGuid();

_JobCalendarEngg.JobCalendarId = JobCalendarId;

_JobCalendarEngg.EngineerId = GuidEngineerId;

en.JobCalendarEnggs.Add(_JobCalendarEngg);

}

It gives me empty

cmb_EnggList.Items

but when i bind it like this.

cmb_EnggList.Items.Clear();

foreach (var record in records)

{

var EnggName = (from k in en.EngineersLibraries

where k.EngineerId == record.EngineerId select k).FirstOrDefault(); Telerik.Web.UI.RadComboBoxItem item = new

Telerik.Web.UI.RadComboBoxItem(EnggName.EngineerName, EnggName.EngineerId.ToString());

cmb_EnggList.Items.Add(item);

}

And post it will give me binded value so in the whole scenario if i bind my drop down in Jquery it binds value in the client page and after post method it gives me an empty list but when i bind the drop down in my server end and when i post it will get me the binded list.
So i require my Jquery binded value to be get in my server list. f

oreach (Telerik.Web.UI.RadComboBoxItem EngineerId in cmb_EnggList.Items)

How to connect SharePoint list to RadGrid

I want to populate a RadGrid with SharePoint 2010 list data. I cannot figure out how this is accomplished.

Here is my ASPX page:

<SPWebControls:SPDataSource runat="server" ID="dsclientmatter" DataSourceMode="ListItem" UseInternalName="true">

<SelectParameters>

<asp:Parameter Name="WebUrl" DefaultValue="/configuration/" />

<asp:Parameter Name="ListID" DefaultValue="4056449D-1884-4C79-AAAD-CD0ABEB2F854" />

<asp:Parameter Name="ListItemID" DefaultValue="1" />

</SelectParameters>

</SPWebControls:SPDataSource>

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" ShowStatusBar="true" PageSize="7" AllowPaging="True" DataSourceID="dsclientmatter" >

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

<MasterTableView datasourceid="">

<CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

<RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False"></FilterMenu>

</telerik:RadGrid>

Here is my code-behind:

protected void Page_Load(object sender, EventArgs e)

{

SPSite site = new SPSite("http://abcdev");

using (SPWeb web = site.OpenWeb())

{

SPList clientlist = web.Lists.TryGetList("clientmatter");

DataTable dt = new DataTable();

SPQuery query = new SPQuery();

query.ViewFields = "<Where><Eq><FieldRef Name='clientid'/><Value Type='Text'>12345</Value></Eq></Where>";

SPListItemCollection items = clientlist.GetItems(query);

if(items != null)

{

if(items.Count > 0)

{

dt = items.GetDataTable();

GridView1.DataSource = dt;

GridView1.DataBind();

}

I don't know if this is the best way to start, but I do know something is wrong because I cant render any data. Plus, I don't understand why by RadGrid ID will not compile. I get an error stating "The name 'GridView1' does not exist in the current context". Why. That is the ID of my RadGrid.

My end goal is to create a RadGrid that I can filter by individual columns, such as: name, client#, topic, etc. I am not sure if the filtering allows for multiple entries, but I would like to be able to filter on more than one criteria. Also, wildcard searches are very important.

Thank you for the help!

Telerik Controls not available in SharePoint

I used the Telerik Control Panel from my SharePoint 2010 server to install the latest ASP.NET AJAX controls. However, the controls are not available when adding Web parts to a SharePoint page. Also, I created a new visual Web part from within Visual Studio 2010 and added a RadComboBox. I then deployed this Web part to my SharePoint server. Visual Studio displays a message that it successfully deployed the Web part. However, after attempting to add my newly deployed Web part to a page, I receive the error "An unexpected error has occurred...."

Is there something beyond the Telerik Control Panel automated installation that is required to make the Telerik AJAX controls available to SharePoint in custom Web parts and on their own?

Problems with upgrading from SharePoint 2010 to SharePoint 2013

Hello,

We are currently in the process of upgrading a number of site collections from SharePoint 2010 to SharePoint 2013.
A few of these site collections uses Telerik Components, for example Telerik RadEditor.

If we open one of these sites we get the following error message:

Could not load file or assembly 'RadEditorSharePoint, Version=5.7.3.0, Culture=neutral, PublicKeyToken=1f131a624888eeed' or one of its dependencies. The system cannot find the file specified.

Our plan is to not do a visual upgrade but instead keep running the sites in SP2010 UI mode whenever possible. We're not sure if this is supported for the Telerik SharePoint 2013 web parts?
What would be the best way to handle this? We assume we have to install the 2013 version of the Telerik components.

We tried installing Telerik_Web_Parts_For_Sharepoint2013_2015_2_826_Trial.msi but that doesn't seem to work. We still get the same error message.

Any help or suggestions would be much appreciated.

How to pass data from one webpart to another webpart in sharepoint?

In certain situation we need to pass data from webpart to another webpart present in the same site. To implement the connection functionality between WebParts, we should create an Interface .This interface will be implemented by both the provider and consumer classes.

Then we will use the ConnectionProvider and ConnectionConsumer attribute to make the connection between the two webpart.

EXAMPLE:

1. Interface :

public interface Test

{

string Name { get; set; }

}

Thanks,

IE 11 - RadButton not displaying embedded icons

We are using telerik version 2017.2.711.45 in our application. We are currently experiencing an issue in IE 11 with Radbutton when rendered as 'lightweight' mode does not display the icons. After some research I found that enabling the font download in the internet explorer settings fixes the issue, but as part of admin policy we are not allowed to make this settings change.

Can you please provide any work around for this.

[Solved] Only allow some file extensions in specific folders at upload

Hi!

I use the file explorer and have a problem I can't find a solution for.
In my file explorer I list my App_Themes folder. Is there a way to set file extensions that are allowed in specific folders at upload?
I just want to enable upload of .css-files in the /css folder and only images such as .jpg, .gif, .png etc in the /images folder.

Is there functionality in file explorer or upload control to help me with my problem.

Maybe I can use some of the javascript events, but I hope there is a simpler solution.

Regards
