I am using Detail Item Template for displaying some extra information on radgrid. I am also using rgSelectedRow css for highlighting selected row. I want to highlight the detail item row for the selected row as well. How can I do this? On the documentation in the following url it is mentioned that "Base row style (rgRow, rgAltRow) is applied according to the parent item’s current style.". But how can I apply some css for selected row's detail item?

I also want to keep a button for users to toggling between displaying detail item template row and not displaying. For achieving this I set the visibility of DetailTemplateItemDataCell object of GridDataItem on Grid Pre Render event. But if I set the visibility to false then the row border is vanished. How can I fix this two issues? I've attached a screenshot. Please help. Thanks in advance

I got this problem on a project I was unfortunate enough to inherit. I databind the imagegallery and set the page size to 10 (I got 16 images).Page 1 : 10 imagesPage 2: All the imagesThe images gallery is implemented on multiple pages and as such need different width, height and page size. This is set via properties and they all have a default value./**/Thumbnail_RadImageGallery.ThumbnailsAreaSettings.Width = Width; (works fine)
 Thumbnail_RadImageGallery.ThumbnailsAreaSettings.Height = Height;(works fine)
 Thumbnail_RadImageGallery.PageSize = PageSize;/**/​Datasouce is Linq-sql into dataview./**/DataTable table = new DataTable(); table.Columns.Add("Title", typeof(string));
 table.Columns.Add("Description", typeof(string));
 table.Columns.Add("ImageData", typeof(string));
 table.Columns.Add("ToolTip", typeof(string));/**/​

Any suggestions?

If this problem cannot be solved quickly, we plan to skip using this imagegallery and use either Ajax or different.

Hi,

I have seen that sets grid properties in PreRender and there is no Rebind but then others (eg. setting header text) that do require ReBind. What are the cases then that will require a call to Rebind for the properties to be set properly?

 

Why I ask: PreRender is so handy because I can handle all grid localization in one call, for both Programmatic and Declarative grids. Rebinding though causes selected rows to get lost so I cannot use that & the only options other than PreRender are to use a combination of Page_Load, ColumnCreated, ItemCreated, ItemDataBound to properly localize all grid items for Programmatic and Declarative grids.

I am having performance issues with a RadWindow containing a large number of controls and two charts across several tabs.  Initial load is very slow, navigation is acceptable but not ideal.  Additionally, restoring from maximized takes way too long.

Link to sample application demonstrating the problem:  removed due to Telerik End User License Agreement for UI for ASP.NET AJAX violation.

Due to an organizational requirement & legacy applications this solution must be run in IE 10.   

Additional information:  Latest version of Telerik.Web.UI, Visual Studio 2012, IE 10.0.9200.17357

Steps to reproduce:

1) Run the solution without debugging to maximize performace

2) Click the button to launch the RadWindow

3) Note the performance between when the page renders and when it becomes navigable.

4) Maximize the RadWindow - slow but acceptable

5) Restore the RadWindow - completely unacceptable

 

I do not know what I can do to make this better and am open to any and all suggestions to do so, including areas outside of the RadWindow itself (web config, master page, etc).  As you can see in the code I have tried RadInputManager as recommended in the documentation and RadMultiPage.RenderSelectedPageOnly (with conditional binding in the code behind) to see if that would improve anything (it did not).   

Please help!

Hi,

Is it possible to use the arrow keys on a keyboard to do a yahoo style scrolling on the radgrid when there is already a scroll bar implemented on the main page?

 

for instance:

 

main page needs a scroll bar because of the size.

rad grid will need a scroll bar

auto scrolling is set to true

page posts back during scrolling with mouse

must be able to use arrow keys for scrolling

 

Even in the examples on your pages I have noticed that you cant use the arrow keys with the scroll bars.  Is this the norm or am i missing something?

 

thanks

I am trying to format a date column to MM/dd/yyyy but reguardless of what formatting I attempt it continues to return M/d/yyyy hh:mm:ss AM.

On load of the page I set the ObjetDataSource and convert to a datatable

 

 I then on the page set the grid to the datasource

 

 and then on the grid item

 

 I have tried  numerous different formatting styles with no success.  I have also tried to change it to a DateTimeColumn and format it there and it stiil continues to show  for example 6/4/2014 12:00:00 AM

 

 

 

Hi 

 

I have incorporated a RadHtmlChart on my application and have all the data binding and series set up done client side. The chart displays and has the required functionality except for one thing:

The first time I click on a legend item nothing happens. After this any subsequent clicks have the desired outcome i.e. the series' and legend item's visibility changes. I am not sure why the initial click does not perform these default functions but the 2nd, 3rd, etc clicks do. Can you help? Is there an initialisation I am missing that is triggered by the first click? Is there an extra bind/refresh/redraw needed?

 I appreciate there is no code listed but I'm hoping this is a generic question that someone can help me with.

 

Thanks

I am having trouble modifying files via RadFileExplorer. 

I have followed all the posts I can find, looked at the Demo's online and tried some of them synergetically. Here is where I am at.

I have a RadGrid "Prometheus" running in a DNN module on the 3.5 framework using the OnNeedDataSource event.

The grid is using AJAX, a RadLoadingPanel, and a RadAjaxManager to handle all the AJAX events.

I am also using the RadGrid Reporting Functionalities but not within the Pager - they are image buttons on the page.

I included the two panels, one asp:panel one telerik:RadAjaxPanel and set the asp:panel's default button but that doesn't seem to work for me. So here is my code:


By setting the javascript args this way, I know that the grid will behavior will exhibit AJAX functionality.

What I would like to do is use the JavaScript to disable the AJAX and produce the needed result. In this scenario if I had only one button (Excel, Pdf, or Word) everything would work fine and I wouldn't be writing this post. So here is the crux of the issue.

No matter which button I press first - the page will attempt to export that type.
so if I click excel it works. Then I decide to click pdf - it exports excel again.

If I simply change the sorting on the radGrid, then click pdf it works normally again. Then I decide to export Word. It once again attempts to export pdf.

And so on...

Obviously, there is something that is storing the export type here... I am thinking that its somewhere in the DOM. Where is it stored, and can I reset or clear it using a JavaScript function?

Thanks In Advance!
