We have a big issue. In some parts of our site the ASP:VALIDATORS, doesn't work.
The exception generated on the server is "This is an invalid script resource request" when from the client the app make the request:
...../ScriptResource.axd?d=1&p=7923ac73-f867-4221-af87-e7a312bdd9fc....

In the Develoment enviorement works perfectly, actually load this .js: (Validators javascript functions)

var Page_ValidationVer = "125";
var Page_IsValid = true;
var Page_BlockSubmit = false;
var Page_InvalidControlToBeFocused = null;
var Page_TextTypes = /^(text|password|file|search|tel|url|email|number|range|color|datetime|date|month|week|time|datetime-local)$/i;
function ValidatorUpdateDisplay(val) {
    if (typeof (val.display) == "string") {
        if (val.display == "None") {
            return;.........................................(I dont want to post the all thing)

We just move our site from a W2003Server to W2012Server.

For a few hours I try with all the solutions related with "unobtrusive validation mode", but finally no one work and we dont use F4.5, we use F4.0.

We try:
- Register the jquery ScriptResourceDefinition in the globlal.asax
- Check all the settings in web.config for *.axd resources
- Add the line "<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />" in the web.config.
- Try to load the jquery.js before the others scripts (adding a ScriptReference in the RadScriptManager)

Any ideas??

Hi, we have a fairly complicated system that is completely generated on the go.

The Grid is the main component and all columns, including template columns are created and populated on the fly.

I use ASP.NET Ajax package.

​we have a mechanism that ignites an Ajax request every n seconds to refresh data in the grid.

We use a Telerik ajax panal for this. 

Whenever the ajax call is received, the Ajax panel recreates the grid from the scratch and then the NeedDataSource event handler (Simply set the datasource of the grid to  

PROBLEM : and the BROWSER memory keeps growing with each refresh until the browser crashes.

When I profiled the browser, I found that even though the browser fires GC it cannot recover memory. 

Browser memory keeps increasing with every refresh and this is proportional to the record count of the grid.

I THINK THE OLD DATA OF THE GRID IS NOT RELEASED WHEN THE GRID IS REFRESHED.

This is the NeedDataSource event handler code. PLEASE REMEMBER THAT I RE-CREATE THE GRID AT REFRESH

        protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            Telerik.Web.UI.RadGrid tmpPointerToUIGrid = sender as Telerik.Web.UI.RadGrid;

            // override default grid page size at the initial run. (the custom paging is not in effect at this stage) 
            if (ssession.DVM.CurrentRequestType != REQUEST_TYPE.DATA_REFRESH && e.RebindReason == GridRebindReason.InitialLoad)
            {
                tmpPointerToUIGrid.PageSize = SymphonySession.FindObject(HttpContext.Current.Session).InitialiseResponse.PageSize.Options.Find(op => op.IsDefault == 1).Value;
            }

            if (ssession.DVM.CurrentRequestType != REQUEST_TYPE.DATA_REFRESH && string.IsNullOrEmpty(tmpPointerToUIGrid.MasterTableView.FilterExpression) && this.Model.FilterCriteria != null && this.Model.FilterCriteria.Count > 0)
            { this.Model.FilterCriteria.Clear(); } // clear filters when no filter is selectered.

            ssession.Trace_addStamp("processing data for grid");
            tmpPointerToUIGrid.DataSource = this.Model.GetDataSource((e.RebindReason == GridRebindReason.InitialLoad) && ssession.DVM.CurrentRequestType != REQUEST_TYPE.DATA_REFRESH, tmpPointerToUIGrid.PageSize, tmpPointerToUIGrid.CurrentPageIndex + 1);

            tmpPointerToUIGrid.MasterTableView.VirtualItemCount = this.Model.GridTotalRowCount;
            ssession.Trace_addStamp("done: data processing");

            if (ssession.DVM.CurrentRequestType != REQUEST_TYPE.DATA_REFRESH)
            {
                this.Model.GridFilterExpression = this.RadGrid1.MasterTableView.FilterExpression;  // save for future refresh commands 
            }

        }

Please help...

Hi,

I have a website with a RadMenu, which works great.
The menu is styled using some CSS.
Now I want to add a RadContextMenu to that same page, but doing so breaks the layout of the RadMenu.

Simply adding an empty contextmenu:
changes the layout of the RadMenu to the default skin (it seems)

This is the RadMenu:
and this is the CSS used to style it:


(The 'hoofdmenu' and 'submenu' classes are given to root and subitems in code)

Any idea how this can happen?

I am getting all kinds of errors when using RadSocialShare.



the errors are:

FB.getLoginStatus() called before calling FB.init(). all.js:56

hi
I have a table field named" Colour_HEX" that has colors in HEX code in this format #808080. I tried binding it but getting an invalid cast exception error.

These are my code:

<ItemTemplate>
                <asp:Label ID="Colour_HEXLabel" runat="server" Width="100px" Height="25px" BackColor='<%# Eval("Colour_HEX") %>'></asp:Label>
</ItemTemplate>

Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.
Exception Details: System.InvalidCastException: Specified cast is not valid.
Source Error: 
 
Line 107: </EditItemTemplate>

How should I solve this? Many thanks
 
 
 

           

I've spend a lot of time trying to update the Telerik components that we use, however I'm left with one issue.

When I hover over the header of a grid, the column header correctly changes its background color, however the area where the text is does not correctly color with it, at least not until I hover over the text as well (and in that case, the color of the font for the text changes and it still looks wrong).

Basically the idea is that when you hover over any place in one of the header column, the background color of that header changes, but nothing else should change.

Does anyone have any ideas?

Attached is a screenshot of how it currently looks (incorrect) and how it used to look when we were using the 2008 version of Telerik.

Here is my CSS:
