how to print radgrid while using master content pages and UserControls.

Hi I want to print radgrid but its not working when using on a usercontrol and then on master page.

please help.

I using the following code in my user control.

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="printTestRadgrid.ascx.cs" Inherits="WebUserControls_Employees_printTestRadgrid" %>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function PrintRadGrid() {

debugger;

var previewWnd = window.open('about:blank', '', '', false);

var sh = '<%= Page.ClientScript.GetWebResourceUrl(radGrid1.GetType(),"Telerik.WebControls.RadControls.Grid.Skins.Default.Styles.css") %>';

sh = sh.replace("&t", "&t");

var styleStr = "<html><head><link href = '" + sh + "' rel='stylesheet' type='text/css'></link>";

var htmlcontent = styleStr + "<body>" + window["radGrid1"].Control.innerHTML + "</body></html>";

htmlcontent = htmlcontent.replace(/<script .*?>(.|\n)*?<\/script>/gi, "")

previewWnd.document.open();

previewWnd.document.write(htmlcontent);

previewWnd.document.close();

previewWnd.print();

previewWnd.close();

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<div class="wrapper">

<div class="topBar">

<p class="headingText">

<asp:LinkButton ID="LinkButton1" runat="server" type="button" Text="[ Print Grid ]"

Font-Underline="false" ForeColor="Black" OnClick="LinkButton1_Click" /></p>

This code-library demonstrates how to print RadGrid without surrounding content<br />

</div>

<telerik:RadGrid ID="radGrid1" runat="server" DataSourceID="SqlDataSource1" Style="margin: 20px;"

AllowPaging="True" AllowSorting="True" AllowFilteringByColumn="True" GridLines="None">

</telerik:RadGrid>

</div>

</telerik:RadAjaxPanel>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:mobily_alexmarConnectionString %>"

SelectCommand="SELECT [EmployeeID], [EmployeeNumber], [EmployeeStatus], [EmployeeName], [EmployeeNameArabic], [FatherName], [Gender], [MeritalStatus], [DateOfBirth], [Email], [PrimaryMobile], [SecondaryMobile], [CurrentAddress] FROM [tbl_Employee]">

</asp:SqlDataSource

>







and in the code behind



 foreach (GridItem item in radGrid1.MasterTableView.GetItems(new GridItemType[] { GridItemType.Pager, GridItemType.FilteringItem }))

            item.Display = false;

  RadAjaxPanel1.ResponseScripts.Add("PrintRadGrid('" + radGrid1.ClientID + "')"); 



please tell me soon

Thanks.





Also when i use radgrid inside a fieldset the ragrid loses its scrolling property and there will b no scrolling for radgrid.

Keyboard support not working with mouse selection

Hello,

In my opinion, the keyboard support demo (Grid - Keyboard Support) shows some odd behaviour in combination with the mouse vs. keyboard selection. The keyboard only fully works when you follow a specific selection pattern.

First the expected behaviour using keyboard selection on the second row:
a.1) Open the demo from the link http://demos.telerik.com/aspnet-ajax/grid/examples/accessibility-and-internationalization/keyboard-support/defaultcs.aspx.
a.2) Select the first row with the mouse.
a.3) Press the down arrow to select the second row.
a.4) Press Enter and the row goes into edit mode. Pressing Escape cancels the edit mode. Great!

Now the same selection, but using the mouse:
b.1) Open the demo in a new browser page.
b.2) Select the second row by clicking clicking on the Contact Name cell.
b.3) Try to start edit mode by pressing Enter. Nothing happens. This is confusing for our users. It worked before?
b.4) Okay, so a small bug. Press the Pencil icon to go into edit mode.
b.5) Press Escape to cancel edit mode. Notice that nothing happen.
b.6) Pressing Enter does work. However, Enter does not work when you start editing after immediatelly pressing the Pencil icon.

I would like to have full keyboard support when using the mouse. The keyboard should work all the time, without telling the user to first use the arrow keys to get the grid into the proper editing mode.

Is this expected behaviour? I noticed the grid has a different mode when I use the arrow keys. Is there some setting I can use?

Best regards,

Marcel

whose description is empty?

I’ll be glad for help,

Slideshow with Paging Enabled / Lazy Loading

We have a number of end-users who are photo-happy and like to have single image galleries containing 200 images or more. When loading all these at the same time, the initial loading of the page is noticeably slow and it's hitting the server harder than it should be (creating all those thumbnails - most of which will never be seen).

To combat this, we've enabled paging and for now set the page size to be 40. Initial testing shows that the page load times go from about 7.5 seconds back down to sub-second load. So that's good. However, it creates a new problem for the end-user, which is (to us) unexpected behavior when the slide-show is running (either full-screen or not). We figured that after the 40th image on page 1, then the 1st image on page 2 would auto-magically be the next shown. Instead, the gallery returns to the 1st image on the 1st page (if looping is on) or just stops (if it's off); forcing the user to click "page 2".

Plus, if the end-user has gone full-screen with the gallery, turned on the slide-show, then clicks to go to page 2; it returns back to the non-full-screen version of the gallery with the new set of images.

Having been with Telerik for almost 10 years now, I know you guys can do better :) A couple suggestions...

Option 1:
The control knows whether or not paging is enabled; it should be able to detect the slide-show index AND page index in order to determine what to do when it hits an upper limit. I'd suggest automatically going to the next page and re-starting the slideshow with the first image - basically doing what the end-user (who *will* get confused doing this) would have to do manually. It that causes a page refresh because it's a post-back then so be it, as long as the rotation continues AND the visible state (full-screen or not) is persisted.

Option 2 (even better):
Implement a lazy-loading scenario for the images. It appears that currently, if we were to load 200 images into the control, that upon the initial loading of the page, all 200 thumbnails are created at the same time instead of just the ones that are currently visible in the thumbnail slider. Perhaps a better solution is to load all the images in the slider with a blank src attribute and instead use data-src; then detecting the visibility of the thumbnail to switch the data-src attribute to be the actual src attribute. Since that would break SEO you'd probably want to make lazy-loading an option - however - in our case we don't want SEO on user-submitted image galleries anyway so that would actually be a good thing for search engines to leave them out of their image searches.

Thanks as always for listening :)

[Solved] collapse - expand When click on Node that have children, without PostBack

Hello,

Undo / Redo not working when using a ToolProvider

I have found that if you are using the ToolProvder for multiple RadEditors that the undo redo functions do not update the content when pressed ore selected from the Undo / Redo toolbar buttons or dropdowns.

The undo / redo works for the RadEditor that is the ToolProvider but not for any that use the first editors toolbar.

This can be replicated on your demo site.

http://demos.telerik.com/aspnet-ajax/editor/examples/toolprovider/defaultcs.aspx

Replication Instructions:

Tick Use Tool Provider
Click apply settings

Type some content in the first editor, press undo - Text entered is removed
Type some content into the second editor, press undo - no changed to the text in this editor.

Note: The dropdown menu still contains a history of undo/redo commands
