Telerik Grid | Pagination control

I have used a telerik grid in my application.

The resultset has around 50 pages. Each page contains 10 records.

I am using pagination in the grid, in which I am using following code:

Control numericPagerControl = gridPager.GetNumericPager();

Control placeHolder = gridPager.FindControl(NUM_PAGER_CONTROL_ID);

placeHolder.Controls.Add(numericPagerControl);

Now, the page numbers are appearing as below:

1 2 3 4 5 6 7 8 9 10 ....

But because of space constraints in the header, I want to display only following string:

1 2 3 4 5 ....

Please revert asap.

How to automatically show print dialog after export to pdf

Hello

I am currently working on a project where it will save a lot of time if I could automatically make the adobe reader plugin to show the print dialog.

I have export to pdf working flawlessly based on the following article.

How To: Export grid to PDF file and show the result using the window
http://www.telerik.com/community/forums/aspnet-ajax/grid/export-to-pdf-and-save-programmatically.aspx

My application basically is using the resulting window to print labels.

It would be wonderful to have the adobe print dialog show up after the resulting window has opened.

On regular web pages it is rather easy using javascript, I am guessing the same javascript will need to be inserted in the created pdf, perhaps the same way as the page break can be inserted using <?hard-pagebreak?> in the grid's output, just not sure how to do it though.

Like always any leads would be highly appreciated.

Thanks
Imran

[Solved] Binding Checkboxes in the list

Hi,

I'm using a RadListBox with CheckBoxes option turned on. I bind the listbox to a table in a DataSet based on an event. The DataSet contains name, id and a bit flag per record (i.e., each row in the datatable would look similar to this: "1", "Joe", true). I set Text and Value using DataTextField and DataValueField respectively. However, I can't seem to find a way to bind the checkboxes. Any ideas?

Thank you!

[Solved] radgrid header style issue with static header and vertical scrollbar

Hi,

here is a link to the screenshot which will explain the problem. I added custom header background image to the grid. The grid uses static headers and verticle scrollbars. Now when scrollbars appear there is no header image above the scrollbar.

[img]http://img65.imageshack.us/img65/7702/gridsmn3.jpg[/img]

Which property do i need to change/set to get this right.

Thanks

Remove style attribute from img

Hi,
I need to replace style attribute from img with plain width and height attributes. I.e.:
YES: <img src="..." height="100" width="200"/>
NO: <img style="height: 100px; width=200px;" src="..."/>

I tried the two solutions you proposed in different posts of this forum, but they don't work completely.
When the editor is in HTML View and OnClientSubmit is triggered, the function doesn't remove style attribute.
When the editor is in Design View, everything is ok.

Why? Is there a workaround?
Following the two solutions proposed.

Thanks.

Solution 1:

    
            <script type="text/javascript">     
        
            function OnClientSubmit(editor, args)     
        
            {     
        
                var images = editor.get_document().getElementsByTagName("IMG");        
        
                for (i=0; i<images.length; i++)     
        
                {     
        
                   var image = images[i];     
        
                   var width = image.width;      
        
                   var height = image.height;     
        
                   image.removeAttribute("style");

Setting ToolProviderId property programmatically

I am using the RadEditor control. The RadEditor is wrapped into a user (ascx) control, and then multiple instances of this user control are being used on a web forms (aspx) page.

I would like to use the ToolProviderID property so that all instances of the RadEditor use the same tools markup and script. However, the RadEditor instances are in different naming containers, so I cannot simply use the ID property of the RadEditor. From a post on your forum (http://www.telerik.com/community/forums/aspnet-ajax/editor/use-toolproviderid-when-radeditor-in-itemtemplate.aspx) I should be able to use the ClientId property of the first RadEditor control as the ToolProviderId value for all of the subseqent rad editors.

I would like to set the ToolPRoviderId property of the RadEditor controls programmatically. My question to you is how early in the ASP.Net eventing pipeline do I have to set this property so that the markup and scripts will be correctly injected into the page?

I find that if I set these properties in the PageLoad event of the containing web forms page via data binding, the ToolProviderId behavior is not correct, since excessive script and markup are inserted into the page. If I set this propery in the OnInit event of the radEditor in the user control (the earliest I can do it in the user control), then everything works fine.

Do you have any guidance of how early in the ASP.Net event pipeline I need to set the ToolProviderId for it to work properly?

Thanks for the help!

Retain row selection on RadGrid after sorting

Hello,
I'm using a telerik(2009.2.826.35) radgrid for listing some items (with sorting and no paging)
on clicking a grid row I'm populating some info in the form (row selected will be highlighted)
However I'm facing with some problem at the time of sorting the columns.

Initially the selected row status is lost. I was able to fix it with the suggestion found under
http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-client-sorting-paging-grouping-filtering.html

However still there is an issue. Follow these steps. (Find below the source.)

Once the grid loads
1) click on any row (selection is made)
2) Sort by any column (initial row selection is retained)
3) Now click on any other row (it is supposed to select the new row and unselect the old row;
It does select the new row; However it fails to unselect the old one)
4) Now click on another row (this time it only selects the new row and unselects the old ones)

FYI: I notice this behaviour only on row selection made immediately after the sorting.
