Hello,

I'm using a RadTabStrip control and I need to hide and show tabs according to a condition and I need it to be using java script, so I'm doing this:

function changeTabVisibility(radTabStripID,tabValue,visible) {
    var tabStrip = $find(radTabStripID);
    var tab = tabStrip.findTabByValue(tabValue);
    tab.set_visible(visible);
}
The problem is that not all the tabs are going to be showed at the beginning, so I need to hide them server side, and if I do a serverTabVariable.Visible=False then is going to fail when I try to set it as visible because the control was never render to the browser.

Basically my question is how can I simulated a tab.set_visible(false); but server side?

I tried doing something like this but it didn't work:

serverTabVariable.Attributes.Add("style", "display:none;"), the tab is been rendered as hide but then I can't set it back to visible.

I hope it is all clear.

Regards,

Hello Team,

Recently we have upgraded telerik control ,so application can works fine on IE 11.

In the application ,we have a RadWindow popup to open the SSRS report but suddenly found that print is not working on IE 11 for SSRS (SQL Server 2008 R2)

Is there any possibility to set the browser Compatibility for IE 9 on RadWindow popup like below

I tried in this way <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9" > but it didn't work because application is set to work on Edge mode.

I just wanted to set browser Compatibility for IE 9 only for RadWindow popup.

Note : There is a aspx page having user control and from user control, RadWindow popup is getting open to show the SSRS report.

Thanks

I am using product version 2013.1.417.45 and I can't get my radgrid to work properly in IE (version 11.0.96) when setting the frozen column count.  Grid seems to work as expected in Chrome.

Here is my grid scrolling set up


I have sorting on some columns (not all), and have widths (in Unit.Pixel) set on column headers and cells; widths vary from column to column but are same for column and corresponding cell.

Please see attached screen shots in both IE and Chrome.

Thank you,
Katie

I'd like to display a child collection of my grid's object data source in the detail item template but I'm not sure how to do the databinding.

The grid is bound using the NeedDataSource event. and there are no available DataKeys that I can use because it builds the data in the code-behind.

How do I bind the child collection to a detail template so I can display in a grid-like format?

I have two DatePickers on an Edit Template of a grid.  When I'm adding a new record or editing an existing record of the grid, the DatePickers are throwing a script error: 'False' is undefined

 I also have enabled AutoPostBack="true" on the first DatePicker as I need to set a second DatePicker with a future date based on the date entered in the first DatePicker.  The Edit Template is wrapped in an Ajax Loading Panel, and based on this link: http://www.telerik.com/forums/146104-datepicker-script-error, I've set the flag EnablePageHeadUpdate to false and I'm still receiving the script error.

 Any ideas?

 Here's my code:

Guys honestly wouldn't it be easy to add an OnClientSelected event to TreeView?  I see you are changing the Div class from "rtBot" to "rtBot rtSelected".  So you know it is happening.  So many people have asked about this over the years and I find it annoying to try and do a hack with the OnKeyPressed.

 Please?

Hi,

For the RadHtmlChart I was wondering if there is any way to change the background color of the main chart area only like you could with RadChart?

Appearance.FillStyle.BackgroundColor controls the background to everything including legend, title and axes

PlotArea.Appearance.FillStyle.BackgroundColor colors the main chart area AND the area behind the y-axis labels which looks a bit odd. I've attached examples with RadChart and RadHtmlChart for comparison. We'd like everything but the main chart area to be transparent so whatever is behind the chart can be displayed, in this case a gray RadDock.

Many thanks,

Andy

 

I have a RadGrid with 24 Template Columns. These columns are generated during runtime based on a dateset. I also set the width of the columns to a set width depending on the size of the data in the columns (although most of the columns are the same size as each other)
 (e.g. col.HeaderStyle.Width = Unit.Pixel(80)). In client settings I have horizontal scrolling enabled (as the grid is a set width but the data is extended) and the FrozenColumnsCount="2".
This all works fine- The correct data displayed, correct widths and when I scroll right the 1st two columns remain where they are whilst the others scroll allowing me to nicely compare.

This Issue is when I scroll to the very far right (the very last column). When the scrollbar reaches the very end all columns including the first two columns that are frozen have their width increased by a noticeable amount. This looks a bit weird and I was hoping to be ale to change some setting so that it doesn't change the width. I've tried many settings such as to set TableLayout in MasterTableView to fixed and set AllowColumnResize to false but this had no effect on the issue.

Do you know of a solution?
Thank You

Code Below:
<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" OnInit="RadGrid1_Init" OnPreRender="RadGrid1_PreRender" OnItemDataBound="RadGrid1_ItemDataBound" CssClass="cssGrid" Skin="Vista" ClientSettings-AllowRowHide="true" 
        ClientSettings-AllowColumnHide="true" ClientSettings-AllowColumnsReorder="true" ClientSettings-AllowKeyboardNavigation="true" 
        AllowFilteringByColumn="false" ClientSettings-Resizing-ClipCellContentOnResize="true" HeaderStyle-Wrap="false" HeaderStyle-CssClass="cssColumns" HeaderStyle-HorizontalAlign="Center">
            <MasterTableView CommandItemDisplay="Bottom" AutoGenerateColumns="false">
<Columns>
...
</Columns>
</MasterTableView>
           <ClientSettings>
                <Resizing AllowColumnResize="true" EnableRealTimeResize="true" ShowRowIndicatorColumn="false" AllowResizeToFit="true" AllowRowResize="true" />
                <Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" FrozenColumnsCount="1" />
                <Selecting AllowRowSelect="true" />
            </ClientSettings>

Hi,

We repurchased our license for the toolkit, in part to get a fix for the issue that we saw was listed as fixed in the release notes...

http://www.telerik.com/products/aspnet-ajax/whats-new/release-history/q3-2011-version-2011-3-1115.aspx

Fixed: RadGrid's horizontal scroll is not moved in IE when having frozen columns and you click on the scroll bar


Before this update, when we clicked on the area to the left or right of the scrollbar, there was no scrolling action.
After the update, we have found that this is fixed.

But, we have found, that if we resize our browser window which causes a resize of our grid (width is set to 100%), horizontal scrolling is broken again.

It will not work until we re-rerender the page, and the grid is re-rendered with the new size, coming from the server. Any client side re-sizing causes the horizontal scrolling to break again for us.

This is occurring in IE 8 and 9 for us.

Thanks,
Rich
