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:

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:

Hello Telerik people,

I would like to have about 8 RadListBoxes on a page and be able to drag and drop an item from one list box to any of the other list boxes. The TransferToID property suggests that I can only have one target, is that correct? If it is possible would you please direct me to an example?

Thanks for your help,

Dave

Hi Team,

I am having a radtreeview in content page and a label in master page.
On selection of tree node in content page I want to update the label text. 

Below is the sample code I am using, but some how the update is not happening.

content page aspx is having: rad tree with RadAjaxManagerProxy.
<telerik:RadTreeView ID="xyz" runat="server" OnClientContextMenuItemClicked="xyz"
                        OnClientContextMenuShowing="xyz" OnClientDoubleClick="xyz"
                        OnClientNodeClicked="xyz" OnClientLoad="AddInfoToMenu" Height="440px">
                        <ContextMenus>
                            <telerik:RadTreeViewContextMenu ID="xyz" runat="server">
                            </telerik:RadTreeViewContextMenu>
                        </ContextMenus>
                    </telerik:RadTreeView>

content page cs contains:
 RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);
        manager.ClientEvents.OnRequestStart = "RequestInitiated";
        manager.ClientEvents.OnResponseEnd = "RequestEnded";
        manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

master page update is happening if I am using a button click. but the node click of handled through ajax request is not updating label control.


Any help appreciated.

thanks

hello

Just trialling UI for ASP.NET and wanted to check this is correct (apologies if obvious, first time user of Telerik controls).

I add a datasource to  grid and the columns appear automatically and I can format etc

When I add a DetailTable the columns from the datasource appear when I run in the browser, but if I want to format I need to go into the 'Columns' section and Add Bound columns and add the DataField property for each column

I would have through the columns would appear automatically (Available Columns) for the detail in the same way they appear for the MasterTableView

thanks

Graham

Ok I've been struggling with this all day and have been all over this site and forums and can't crack this one. I think the issue is I do not know the proper syntax for the regular expression but not sure. It is a bool field that is populating a GridBoundColumn. The text that appears in the results is "True" or "False"

So the use case is to auto default my grid to show only records where the Active field equals true. The grid was populating successfully everything was working beautifully up until I tired to add the default filter.

(some irrelevant code has been removed for privacy)


Code behind


error message

Server Error in '/' Application.

No property or field 'Active' exists in type 'DataRowView'

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: Telerik.Web.UI.ParseException: No property or field 'Active' exists in type 'DataRowView'



Additional syntax that has been tried but was also unsuccessful

[Active] = 'true'
[Active] = 'True'
Active = 'true'
Active = True
[Active] EqualTo 'true'
[Active] EqualTo 'True'
[Active] EqualTo true
[Active] EqualTo True

Any help would be great!
