PageLayout GridType = Fluid issue on Chrome

Hi,

When I'm setting the "GridType" property to "Fluid", it isn't fitting the full width on Chrome.

It works as expected on IE8 but not with Chrome, I always have a left and right margin.

Is there a way to fix this issue ?

Thanks, Rémi.

Problem moving server from iis 7 to 7.5

I am in the process of moving my site built with Q3 2013 control set and running on iis 7.0 to a new server running iis 7.5. In both case the server is windows server 2008 R2.

The problem is that after transferring all the files, including web.config and the telerik dlls in /bin to the new server, the ajax function has stooped working. symptoms: drop list does not display, buttons are not active and do not submit forms etc .

I did upload a standard ajax toolkit menu to make sure it was not inability to run ajax per se, and it is OK.

I have a feeling the answer lies in web.config, but I try to leave well alone if possible, since this is a legacy site and I don't plan any development work on it; i just want to relocate to a new server!

Can anyone suggest where the problem might lie, or how I can find out what it is?

Thanks

Clive

i am not able to download the file. and not able to disable ajax. the file is saved in db in byte format

message - Error: 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.

[Solved] Access filter container from Page_Load

Hi,

I have a fully programmatically implemented Radgrid, with filters enabled. When you implement a Filter Template Class (to make a custom filter), you have to implement the function InstantiateIn, which has the container as a parameter. In this function you add the components of your Filter Template to this container, but I want to add controls to the container from outside this function. Is it possible to find this container form the Page_Load function? I've serached everything, and I have seen that you can get it at ItemCreated or ItemDataBound, I don't exactly remember. But this is not what I want, I want to get it from Page_Load. How can I do that?

Thanks

RadGrid virtualization and Editing

Going through the radgrid documentation there is a limitation that we cannot use the BatchEdit or inplace Mode with virtualization.

What is the alternate or workaround to that?

My client do not want to use paging but want to provide the editing feature on the GRID which has thousands of records. Additionally performance has to be handled as number of records in the GRID can be of order of 000's so definitely need to use virtualization or paging.

Any suggestion on to get around this and achieve this functionality.

[Solved] TreeView is not getting refreshed when I bind it from AjaxManager_AjaxReqest

Dear Team,

I'm displaying hierarchical data using Treeview. We need to change the datasource of treeview dynamically based on user input. I'm using the below code do achieve the functionality:

In ASPX:

function LoadTreeView(projectid) {

var ajaxManager = $find("<%= RadAjaxManagerforGrid.ClientID %>");

ajaxManager.ajaxRequest("treeview_databind," + projectid);

}

In Code behind:

protected void RadAjaxManagerforGrid_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string[] arguments = e.Argument.Split(',');

if (arguments[0] == "search")

{

string _search = arguments[1];
