I have a RadGrid linked to a datasource that acts as a live dashboard.  On a timer, asp:Timer, I rebind the grid to retrieve the new data values and update the RadGrid.  Doing this causes the RadGrid to refresh and for a moment the page flashes.  Functionally everything works fine, but this flash is distracting to the user.

 

What can I do to remove this flash?  Are there any double-buffering type techniques I can use?  To force an update of the RadGrid do I have to rebind or is there some other method I can use?

 

thanks

I am using a grid 2014 Q3 that has 4 columns: Service, Unit, Price, TotalPrice. The grid is in Batch Edit mode using client-side api.

Each column has <ItemTemplate> and <ItemEditTemplate>.
Column 1: Inside <ItemEditTemplate> I have a RadDropDownList.
Column 2: Inside <ItemEditTemplate> I have a RadNumericTextBox for Units.
Column 3: Inside <ItemEditTemplate> I have a RadNumericTextBox for Price.
Column 4: Inside <ItemEditTemplate> I have a RadNumericTextBox for TotalPrice.

I have tried to do the following for the last couple of days with little success:
1. Calculate total price when user enters a value in unit and/or price column.
2. Update column 4 with total price.

I subscribed to various client events, such as BatchEditClosed, BatchEditCellValueChanged. I noticed the client-side function is called 4 times, one for each cell.

Is there a way I can do the following:

1. Get the row once edit mode is complete/closed and have the function called once.
2. Get the values for each cell.
3. Calculate total price.
4. Update TotalPrice column with calculated value.

Could you please provide guidance with sample code snippet?

Thanks,
Tan

I have a requirement to provide the user a visual indicator that they are logged in and a selection drop-down for which user profile they want to be using. This requirement is accross the application and I would like to place these functions into the RadNavigation {or RadMenu, whichever is best} on the master page.

 Piecing things together I think the following is the right approach. Please advise on corrections and/or better ways to do this.

1) in the site-map, the add two nodes titled 'userSamAccount' and 'userProfile'

2) create one custom databound template for displaying the active directory name, and another for displaying the profile drop-down items : http://www.telerik.com/help/aspnet-ajax/navigation-server-side-templates.html

3) on Template Needed, if node title is 'userSamAccount' or 'userProfile', align to the right via css {below} and change their templates to the custom ones.

 

Will this work?

Hi,
I am building my columns as below, but the caption remains as "MYCOL" as opposed to "My Column", this seems incorrect?

Hi, 
I am on working demo project on how spell check works and how to use in my project. while doing that, i have a requirement 
1. To keep the focus on "Not In dictionary" Div/Text Area 
2. Set the tab controls order in my own way. 

I did not find any snippet or code block which i can read the spell check dialog/form controls either javascript or .net code behind.

Hello,

I have a radgrid on my page. It has a Details Table for children. For the parent rows that have no children I do now want any row(s) to show. I have used the below code and when I do, I still see a blank row underneath my parent row. What am I doing wrong?

The attached file is how my grid looks.

Hello,

I use a RadTooltipManager with AutoTooltipify="true" in the MasterPage of my Solution. And I have a page .aspx with 70 RadDatePicker and there is a problem of performance because it's very slow for to access the page (slower in IE).
​

I make a page of demo with 75 RadDatePicker and a RadTooltipManager in the MasterPage and I use the UI Responsiveness of the F12 developer tools of IE.

Result in the first attachement. The event DOMContentLoaded has a duration of 3sec ! And I seen that the majority of instructions is the update of css style of each day cell tooltip of each RadDatePicker in the page (style.visibility="hidden" and style.display="none").


So, I set ShowDayCellToolTips="false" for all RadDatePicker of my demo (because these tooltips is useless for us) and I restart with the UI Responsiveness.

Result in the second attachement. So, yes the duration of the DOMContentLoaded has a duration of 1.2sec now but there are always the updates of css style of each tooltip in the page like before. And I want to know why the RadTooltipManager set the css style of each day cell tooltip(with ShowDayCellToolTips="false") ? And what can i do for more optimizing for the postback of this page ?

I have a RadListBox that has items which are wiped and binded every 4 seconds. I have a linkbutton in each listbox item that I want to open a tooltip. At the moment I use a RadToolTipManager, the content in an ASCX file, and an OnAjaxUpdate function. This -sort of- works but the content in the tooltip is broken when the radlistbox refreshes on the timer.

Realistically I'll only ever have one RadToolTip open at once, and the content it loads (four linkbuttons) won't be changing. I have tried other methods like putting a RadToolTip directly into the listboxes ItemTemplate, but then the tooltip closes itself every time the listbox refreshes/posts-back. I'd love to avoid the whole ToolTipManager + ASCX thing because it loads goofy and shows a loading panel every time it opens.
