ASP.net Forms - should I be using Telerik AJAX?

Just getting started with Telerik controls.

I have an older ASP.net Forms system that I need to maintain. Upcoming Change Request will involve updating or re-doing several reports. Also, the website could use some better looking pages.

Question is... which Telerik product should I be using for a ASP.net Forms application?

Is it the ASP.net AJAX?

Thanks,

handling huge volume of data in datagrid

Hi

We are having a situation in which the grid is binded to millions of rows and we can’t afford network traffic to pull all the data and then filter.

So I would like to know Is there any way in telerik radgrid to handle filter the data server side using stored procedures instead of pulling all the data and filtering in the client side?

Custom skin display problem

Hello,

Im having issues with the new telerik theme builder avaible here http://themebuilder.telerik.com/
I created a skin based on Material skin with orange color instead of green.
Then, I placed the files in my App_Theme folder, set EnableEmbeddedSkin to false and Default Skin to "Avanti" (the name of the skin).
However, im getting strange behavior and can't get the skin to render properly.

I attached a screenshot of the result.

What could cause this ?

Saving spreadsheets

Hello,

I want the current spreadsheet (imported or just started new) after any changes to be saved somewhere (preferably to Session) so that when I reload the page or navigate to different page and return, the same spreadsheet would load up.

Thank you for any info.

Frozen Column Scrolling Issues

On a grid with varying sized columns, when I freeze some columns and then attempt to scroll horizontally, the grid scrolls very oddly.

For example, my grid columns that are scrollable (outside the frozen column count) are Last Name, First Name, SSN as well as many others. Last Name and First Name have 120px as their widths. The SSN is 60px wide. When I scroll to the right

The SSN "scrolls" left and assumes the size of the First Name. First Name goes left. The sizing is one issue. But several columns to the right of that appear to scroll first. This is not the desired effect.

I need to scroll by column only or by pixel or something. This scrolling effect isn't acceptable.

Declarations:

<telerik:RadGrid ID="grdList" runat="server" AllowPaging="True" AutoGenerateColumns="false" AllowAutomaticInserts="true" AllowSorting="True" PageSize="25" Height="600px" GroupingSettings-CaseSensitive ="false" EnableLinqExpressions="false" >

<MasterTableView TableLayout="Auto" ClientDataKeyNames="Key" EditMode="InPlace" CommandItemDisplay="TopAndBottom" AllowFilteringByColumn="true" HeaderStyle-Font-Size="10px" ItemStyle-Font-Size="10px" FilterItemStyle-Font-Size="10px">

<ClientSettings>

<Resizing AllowColumnResize="true" AllowRowResize="true" ResizeGridOnColumnResize="true" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="4" />

<Selecting AllowRowSelect="true" />

<ClientEvents OnCommand="RaiseCommand" />

</ClientSettings>

Remainder of the content was omitted for brevity.

Thanks,
Matt

EDIT: To clarify, the scrolling works perfectly if I do not set FrozenColumnsCount. It scrolls basically by "pixel" I would say. But when I set FrozenColumnsCount, it is like it scrolls by pixel sorta... but "snaps" to columns. And it does not do a very good job at it.

Set authorization for client side databinding

Is there a way to submit an authorization header with the ajax request on the client data bind? I cant seem to find anything that would allow me to do something like this

<script type="text/javascript">

//<![CDATA[

function ParameterMap(sender, args) {

//If you want to send a parameter to the select call you can modify the if

//statement to check whether the request type is 'read':

//if (args.get_type() == "read" && args.get_data()) {

if (args.get_type() != "read" && args.get_data()) {

args.set_parameterFormat({ customersJSON: kendo.stringify(args.get_data().models) });

}

function Parse(sender, args) {

var response = args.get_response().d;

if (response) {

args.set_parsedData(response.Data);

}

function UserAction(sender, args) {

if (sender.get_batchEditingManager().hasChanges(sender.get_masterTableView()) &&

!confirm("Any changes will be cleared. Are you sure you want to perform this action?")) {

args.set_cancel(true);

}

//]]>

</script>

Scheduler Accessibility

I work for Local Government in the UK. I'm trying to make our web site accessible in time for the UK Government's upcoming deadline of September 2020 for Level AA compliance.

This Scheduler accessibility page states it is Level AA compliant:

https://demos.telerik.com/aspnet-ajax/scheduler/examples/accessibility/defaultvb.aspx

But I'm getting the following 3 failures, which your demo page above also fails on:

Each a element must contain text or an img with an alt attribute. WCAG 2.1 A F89, Section 508 (2017) A F89
Identify row and column headers in data tables using th elements, and mark layout tables with role=presentation. WCAG 2.1 A F91, Section 508 (2017) A F91
This page uses nested tables, which do not make sense when read in a screen reader. WCAG 2.1 A F49, Section 508 (2017) A F49

I'm using the latest 617 release. Am I missing something?
