Hello,

I need to be able to keep the caret in the same location on a masked textbox when a user leaves our webpage (switches tabs) and comes back.

Currently, if the user enters some text, '123', and then goes to a different tab and comes back, the caret does not remain after the '3'.  It has moved to the end of the mask.

This happens regardless of whether I set the SelectionOnFocus attribute to "None" or not.

A standard asp textbox keeps the caret in the same location.  If I type "test" and leave the caret between the 'e' and the 's'.  Tab away and come back, the caret is still in the same location.  Is there another attribute I need to use in order to replicate this functionality?  Or in other words, stop the caret from moving?

Regards,
Chris

Hi,

I'm trying to use the code from this demo http://telerikwatch.com/2008/09/telerik-watch-minute-enhancing-radgrid.html. The problem I'm having is I get this error the second time I try to edit the filter textbox and hit Enter. This seems to be happening in all browsers.



This is a very complex page so I can't copy all the code here. So, here is an idea of what is going on that may be helpful:

       1. Columns are dynamically created with AutoPostBackonFilter = false (I've tried both ways)
       2. Using RadAjaxManager to update grid and controls.
       3. There is a ASP:Panel around the grid with the DefaultButton set to a control to keep it from randomly launching other buttons     on the page.
       4. Using RadComboxes in the grid also. They are all working fine and are using the masterTableView.filter() function.    

Any help would be appreciated.

Possible offending code:

,_recreateControls:function(e){var d=e.getElementsByTagName("*");

for(var a=0,c=d.length;

a<c;

a++){var f=d[a];

if(typeof(f.id)!="undefined"&&f.id!=""){var b=$find(f.id);

if(!b){continue;

}b._element=$get(f.id);

}}},getColumnByUniqueName:function(a){for(var b=0;

b<this.get_columns().length;

b++){if(this.get_columns()[b].get_element().UniqueName==a){return this.get_columns()[b];

}}return null;

Hi, 

I am successfully able to use radgrid for inline insert.

However, on click of add a new item, the grid goes to the last page showing the items in the end.

Is there a way to force the grid to display the same items? (ie, remain on the same page)

Thanks
Vishesh

I am creating a new instance of a popup and then adding the OnClientResize,
When the popup opens/loads the function is fired, however it is never fired again when resizing.

However, if i add it to the radwindowmanager, and assign the same function to it, it will work every time.
I do not wish to add it it to the radwindowmanager as the function i need to call is not available on that page.

Any help with this would be much appreciated.

Hi Telerik,

After a week of researching this topic it seems that most people are confused about how to use RadAjaxManagerProxy when creating MasterPage/ContentPage sites and WebUserControls.

The problem with not being able to insert a RadAjaxManager in a ContentPage/UserControl is that if you call the clientside function ajaxRequest your call is made to the RadAjaxManager server side function, which you have no control over when you're developing the contentpage or usercontrol. We need to be able to fire callbacks and catch them in the contentpage or webusercontrol.

I know you can use ajaxRequestWithTarget but this has two problems - it requires you to register the expected postback variables in the Page or UserControl Render function as follows:


And then you have to catch the event on the server side in RaisePostBackEvent - which implies that ajaxRequestWithTarget does a postback, not a callback like ajaxRequest, which is less efficient. The reason you need to register the expected postback variables is because if you don't, you'll get a security error from Asp.Net: "Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument" - meaning that ASP is preventing this postback because it doesn't know the data being posted since it wasn't in the ViewState for the target specified in ajaxRequestWithTarget. Also, it's not an elegant solution when you have to add a hidden button to your page which does the postback for you.

Most developers are now moving to nice elegant jQuery solutions that make callbacks everywhere, and if RadAjax does not have an elegant way to make callbacks simple then it's not a workable solution. 

I really like the simple way you can make a callback via the RadAjaxManager, but we really need this functionality in the RadAjaxManagerProxy as well!

I have read the post on a custom provider to get to the root folder in the ViewPaths property but I can't get it to work.  Is there any update or another way to use a physical path or to set the viewpathproperty to the root folder?

Hi,

Telerik Grid Version: Telerik Grid ASP. NET AJAX Q1 2010 SP1

Requirements:
We need to build a self-referencing RadGrid with custom columns (ca 200 - 500 columns), inline editing and yahoo scrolling (ca 500 - 5000 rows).

• Why Custom columns

The grid datasource should have 24 x 5 = 120 columns at least but the grid itself should show at least 24 columns (2 years = 2 x 12 months).
However, each row should show the content of 5 fields (that's why we need overall 24 x 5 = 120 columns).

• Why inline Edit

The user should be able to edit only 1 of the 5 fields per row. We tried double edit click, but for performance reason, it didnt work well.

• Why yahoo scrolling

To improve performance and for better usability, the user shouldnt wait before all the rows are rendered before editing them.

• Why self-referencing

The grid shows tasks with level and outline numbers. The user want to see a hierarchy, so he can collapse/expand task from any level.

See the picture "preview" in attachment to see how the grid currently looks

Problem:
We could successfully implement the grid with custom column, inline editing and yahoo scrolling. Everything so far is working fine.
Our only problem now is to make the grid self-referencing.
When trying this, we have an Error "System.OutOfMemoryException".
When debugging, we found that, this error occurs just after RadGrid1_NeedDataSource in RadGrid1_ColumnCreated
We suspect that the problem has to do with the huge amount of columns (around 100) and the fact that we enable self-referencing.

Any Idea or suggestions?

Code:
The grid is created programmatically because the columns are created dynamically.

aspx : The grid will be later added in PlaceHolder1

page_init

page_load

RadGrid1_NeedDataSource

RadGrid1_ColumnCreated

in my grid the EditMode is "EditForms". I also have a ItemEditTemplate which contains the update and cancel button. Is there a way that i can disable/hide the default update and cancel buttons and use mine?

Dear Telerik Team

I have used the Rad Toolbar in a user control file.

and I dragged this user control on my Web Form page to use it.

I handle the events of Rad Toolbar items in my web form page (Event Bubbling).

When I run my application, the problem that I faced is when clicking any item in Rad Toolbar ----> No Post Back happened !!!!

and so My event handlers cannot run !!

so, What is the problem ? and How I can solve it ???

Best Regards
