Hello All,

The situation:

We have a project in Visual Studio 2010 (with TFS) that is using the Telerik.Web.UI.dll.

The problem:

Whenever any one of the developers builds and runs the project, the Telerik dll's are automatically checked out and locked for that developer.  This makes the other developers unable to run the project until it's checked back in.

The question:

Is there something about the Telerik software that requires this, or is it completely unrelated to Telerik and merely a VS configuration problem? 

The gratitude:

Thanks, in advance.

Hi, I have a problem about RadGrid.
I put two RadDatePricers in RadGrid . When the RadGrid first show up , some contents showed in the RadGrid will show up outside the bottom border of the RadGrid,  after two seconds , the contents showed outside the bottom disappear automatically and everything is ok.
Is there any way to resolve the problem?

Hello,

I have a RadTreeView control in my application that can potentially contain a large number of nodes.  When it does contain a large number of nodes, I get the error:

"Error during serialization or deserialization using the JSON JavaScriptSerializer.  The length of the string exceeds the value set on the maxJsonLength property."

Normally, I would increase the maxJsonLength value in my web.config, however my application is being installed into SharePoint Central Administration as a feature, and I cannot modify maxJsonLength in Central Admin's web.config for a variety of reasons.

I would like to disable AJAX completely so that JSON serialization is not used - it's okay if the control takes a while to load, plus I am limiting the user to merely expanding and selecting nodes.  Is this possible?

Thanks,
Leigh

The treeview definition (nodes are added in code during page load):

while accessing the addnew control insert button in my rad grid. my grid disappears. I don't know how to fix this prob. If any body knows pls let me know. This is my snippet:

I'm trying to use the RadFilter to work around the following limitation:

"RadGrid's filtering does not support "Between" FilterFunction when the RadGrid is bound to the EntityDataSource."

What I need is a Filter showing only one field (Date) that appears on startup. Much of the Filter UI should be hidden, including the TimePickers. I've attached a picture of what the desired result.

Any ideas how I can build a stripdown version of the RadFilter like this?

Thanks,

Hi,
I've created a custom module with a RadGrid in the backed to manage the module's items. I have a LinkButton inside a RadGrid GridTemplateColumn which I use to send a PDF document from a database to the user. I ran into the issue described in this thread:
http://www.telerik.com/community/forums/aspnet/ajax/radgrid-response-binarywrite-asp-net-ajax.aspx
I used the solution suggested in that thread adding an event like this one to the grid page:

protected void RadGrid1_ItemCreated(object sender, Telerik.WebControls.GridItemEventArgs e)

    {

        if (e.Item is GridDataItem)

        {

            Button btn = (e.Item as GridDataItem)["TemplateColumn"].FindControl("Button1") as Button;

            ScriptManager1.RegisterPostBackControl(btn);

        }

        if (e.Item is GridCommandItem)

        {

            Button btncmd = (e.Item as GridCommandItem).FindControl("Button2") as Button;

            ScriptManager1.RegisterPostBackControl(btncmd);

        }

    }

This seemed to fix the problem, but then I noticed if I make the grid sortable and I click on a column header to sort the items, then I click on any item's LinkButton, I get again the Sys.WebForms.PageRequestManagerParserErrorException. Same happens if I enable grouping and group the items by any column.

This is the LinkButton codebehind:

protected void ItemsGrid_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

    {

        if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

        {

            Guid candidaturaId = new Guid(ItemsGrid.MasterTableView.DataKeyValues[e.Item.ItemIndex]["ID"].ToString());

 

        // create a new instance of ContactsManager with default provider

        CandidatureManager cm = new CandidatureManager();

 

        // get the desired candidatura and set the values of the form

        ICandidatura candidatura = cm.GetCandidatura(candidaturaId);

 

            string ext = Path.GetExtension(candidatura.AllegatoFilename).ToLower();

            CustomDownload cd =

                new CustomDownload

                {

                    Filename = candidatura.AllegatoFilename,

                    MimeType = (ext == ".pdf") ? MediaTypeNames.Application.Pdf : "application/unknown",

                    Data = candidatura.Allegato.ToArray(),

                };

 

            ScriptManager sm = (ScriptManager)Page.FindControl("TheScriptManager");

 

            Response.ClearHeaders();

            Response.ClearContent();

            Response.AddHeader("Accept-Ranges", cd.Data.Length.ToString());

            Response.AddHeader("Content-Disposition", "attachment;filename=" + cd.Filename);

            Response.ContentType = cd.MimeType;

            if (cd.Data.Length > 0)

                Response.BinaryWrite(cd.Data);

            Response.End();

        }

    }

Hi All,

Please go through the below link in Firefox 4.
http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextmenu/defaultcs.aspx
When I Show/Hide the columns using Context Menu it is not auto - adjusting the width of the grid. It leaves an empty space
at the right hand side.Though it is working fine in IE(Internet Explorer) and lower versions of Firefox.
Can you please suggest how to get rid of this space so that it auto-adjusts itself.
Expecting for an early reply.

Thanks,
Amrita Mandal

I have recently took over a project from someone else and am experiencing some inconsistencies when it comes to getting/setting html in firefox. 

When i use get_html i want to always have my content wrapped in HTML tags. So if i type a few words it should be wrapped a <p> tag when i use get_html. This works for hte most part but with a couple inconsistencies:

1) When i set my HTML using set_html , if my content is empty i must set "<p>&nbsp;</p>"  or else setting it to empty text will just return straight text when i use get_html if i just type a few words without any styling/line breaks.
2) Setting it to <p>&nbsp;</p> when the content is empty works fine when i use get_html. Everything is wrapped in a <p> tag how i want it but if i highlight/delete the content then start again sometimes (but not always) the <p> tags disappear and i get straight text and no HTML. 
3) If i use <p></p> in Firefox when i have no content to set the return results are "<p></p>" then my text, but in IE the text appears inside the <p> tag. 

I really just want to enforce always having formatted HTML when i use get_html. No text should be coming back outside of html tags. 

I have the following ContentFilters set up:
ContentFilters="ConvertCharactersToEntities,ConvertFontToSpan,ConvertToXhtml,FixUlBoldItalic,OptimizeSpans,RemoveScripts"

Also not sure if this is a big deal but the editor is in a jquery dialog and the content is set on button click like so:


i know there are some known issues with the version of firefox i am using (3.6.15) and the editor as you can tell by the focus trick needed to get it to work. I just want to see if there are any other ways to go about doing what i want. thanks

I've noticed in Firefox 3.6.16 that after I click a noncheck button on the toolbar meant for single clicking purposes, an outline is formed around the button, and doesn't go away until I click somewhere else on the browser.  Is there a way to make it so the button doesn't stay outlined after I click it, so that it merely goes back to how it looked before it was clicked.  I've also noticed this doesn't happen in Internet Explorer.

I have two ListView's on a page and I want to associate one with the other. That is, selecting an item in the first list view will then display related data in the second list view. I've Googled, but can't find a good example of this scenario.

Is there an example or sample code I can review to help me figure this out?

Thanks!
Mark
