We are using telerik old version which was using dll of rad controls.Now we are upgrading these controls to latest version of telerik and getting more code issue which was not working .

My following code is not working , So please let us know How we can fixed this issue.

Telerik.Web.UI.RadTreeView was unable to find an embedded skin with the name '~/RadControls/TreeView/Skins/Arrows/3DBlue'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

<telerik:RadTreeView ID="rtvTopLeftPatientMenu" Skin="Arrows/3DBlue"
runat="server" OnNodeClick="rtvTopLeftPatientMenu_NodeClick"
BeforeClientToggle = "BeforeToggleHandler" BeforeClientClick = "BeforeClientClick" >

Enter Page Number with SEO Paging with Routing turned on not working

I have a RadGrid with SEO Paging and Routing turned on. I'm using the NextPrevNumericAndAdvanced mode with TopAndBottom position.

When entering a custom page number (i.e. page 33 of 66) and click on the go button it just goes to the current page.

The individual page number buttons are fine (except the CSS issue I've reported before) and go to the correct page.

RegularExpressionValidator only on a specific button

I followed the attached example to create a RegularExpressionValidator for a input.

I have 3 inputs (2 DateTimePicker & 1 RadTextBox" and 5 "RadButton") to operate several actions. I now want that only the click on 3 of my 5 buttons make the validation of a specific "RadTextBox" because its an extra that is not always used.

Now, no matter which button I press I get the check for the RadTextBox and Error message presented.

Is there a filter or specification tag that I can use, that the RegularExpressionValidator use only my selected buttons?

(C#; VS2015; ASP 4.5; Win 7; UI for ASP.net AJAX latest Version)

Thanks

RadScriptManager

I have various applications running on windows server 2008 and IIS 7 (.net 4.0 and 4.5). For some reason any application using the RadScriptManager is now throwing a 404 error on all .axd files and a "sys is not defined" error. The strange thing is that if I switch the the asp:scriptmanager these applications work correctly. Is there a setting on the server or in IIS that could cause this behavior? I am using version 2012.2.912.40 and 2013.3.1015.45 and they are both exhibiting the same behavior.

As validate the MinDate equal to 6 months before the current date current date

I need to validate that the minimum date to select is equal to 6 months before the current date.
For example: Today's date = 21.10.2015
this.dt_Date.MaxDate = DateTime.Now; so

How to fetch values from EditIemTemplate of a dynamic GridTemplateColumn in batch edit mode

I have a radgrid that I am dynamically creating in the Page_Init method as mentioned here. I have multiple templated columns that dispaly a label in the ItemTemplate and a RadComboBox and RadTimePicker in the EditItemTemplate. Both are properly displayed. However, on editing in batch mode, I am only able to get the value of the radcombobox and not of the time picker. I have noticed that the DataBinding events of my EditItemTemplate controls do not fire at all. Even the overridden ExtractValues method doesnt hit my breakpoint. Have attached the code..Any help is appreciated.

public class MyItemTemplate : IBindableTemplate

{

protected Label lblProj;

private string colName;

public MyItemTemplate(string cName)

{

colName = cName;

}

public void InstantiateIn(System.Web.UI.Control container)

{

lblProj = new Label();

lblProj.ID = "ProjTime_" + colName;

lblProj.Width = Unit.Pixel(140);

lblProj.DataBinding += new EventHandler(lblProj_DataBinding);

container.Controls.Add(lblProj);

}

void lblProj_DataBinding(object sender, EventArgs e)

{

Label lblProj = (Label)sender;

GridDataItem container = (GridDataItem)lblProj.NamingContainer;

lblProj.Text = ((DataRowView)container.DataItem)[colName].ToString();

}

public IOrderedDictionary ExtractValues(Control container)

{

OrderedDictionary values = new OrderedDictionary();

return values;

}

}

public class MyEditTemplate : ITemplate
   {
       protected RadComboBox PDay;
       protected static string date;
       protected static string time;
       protected RadTimePicker PTime;
       private string colName;
       
       public MyEditTemplate(string cName)
       {
           colName = cName;
           
       }
 
       public IOrderedDictionary ExtractValues(Control container) 
       { //breakpoint here doesnt get hit
           OrderedDictionary values = new OrderedDictionary();
                       return values;
       }
 
       
       public void InstantiateIn(System.Web.UI.Control container)
       {
           PDay = new RadComboBox();
           PDay.ID = "PDay_" + colName;
           PDay.Width = Unit.Pixel(150);
           PDay.AllowCustomText = true;
           PDay.DataBinding += new EventHandler(PDay_DataBinding);
 
           //adding Items to PDay.Items here
 
           PTime = new RadTimePicker();
           PTime .ID = "PTime_" + colName;
           PTime .Width = Unit.Pixel(100);
           PTime .DataBinding += new EventHandler(PTime_DataBinding);
           PTime .DateInput.ReadOnly = true;
 
           container.Controls.Add(PDay);
           container.Controls.Add(PTime );
 
       }
 
       void PTime_DataBinding(object sender, EventArgs e)
       { //breakpoint here doesnt get hit
           RadTimePicker timePicker = (RadTimePicker)sender;
           GridDataItem container = (GridDataItem)timePicker.NamingContainer;
           timePicker.SelectedDate = Convert.ToDateTime(((DataRowView)container.DataItem)[colName].ToString());
                   }
 
 
       public void PDay_DataBinding(object sender, EventArgs e)
       { //breakpoint here doesnt get hit
           RadComboBox cBox = (RadComboBox)sender;
           GridDataItem container = (GridDataItem)cBox.NamingContainer;
           cBox.Text = ((DataRowView)container.DataItem)[colName].ToString();
         }

Integrating RadUpload with SharePoint 2010 - HTTP 404

Hello,

In order to integrate RadUpload control with SharePoint 2010 (IIS 7.5) I wrote an application page MyCustomUpload.aspx:

{

public partial class MyCustomUpload : LayoutsPageBase

repeaterResults.DataBind();

labelNoResults.Visible = false;

repeaterResults.Visible = true;

}

else

{

labelNoResults.Visible = true;

repeaterResults.Visible = false;

}

I'm using the standard .net ScriptManager provided in default SP master page.
I was able to upload files with no additional configuration but no progress bar was displayed and I received a warning pop-up every time the file was uploaded. Following these instructions (for IIS7): http://www.telerik.com/help/aspnet-ajax/moss-progress-area-in-moss.html and http://www.telerik.com/help/aspnet/upload/uploadinglargefiles.html I configured the progress handler and upload limits.

Here are some parts of my web.config file (for SP web app):

<system.webServer>

<security>

<requestFiltering allowDoubleEscaping="true">

<requestLimits maxAllowedContentLength="2147483647" />

</requestFiltering>

</security>

...

<httpRuntime maxRequestLength="1024000" executionTimeout="3600" />

...

<modules runAllManagedModulesForAllRequests="true">

...

<add name="RadUploadHttpModule" type=

preCondition="integratedMode" />

</modules>

<handlers>

...

<add path="Telerik.RadUploadProgressHandler.ashx" type=

verb="*" preCondition="integratedMode" name="Telerik_RadUploadProgressHandler_ashx" />

</handlers>

</system.webServer>

</location>

<location path="Telerik.Web.UI.WebResource.axd">

<system.web>

<authorization>

<allow users="*" />

</authorization>

</system.web>

</location>

I've also changed the C:\Windows\System32\inetsrv\config\applicationHost.config file as described in documentation:

<section name="requestFiltering" overridemodedefault="Allow" />

in all sectionGroups where it occurred.

Now when I'm trying to upload a file I get 404 and no files are uploaded to target folder.

I've read some posts on this forum related with RadUpload and http 404 problems but none of them were helpful in my case.

Could you please help me to solve this problem?
