Hi

I am using Radwindow as a modal popup for inline form editing.  I have created a wizard, using standard 'asp:panels', inside the ContentTemplate of the Radwindow to break up the form in to smaller chunks. In each asp:panel there is a 'next' and 'back' button which is used to navigate between them. These buttons control server side functions to show/hide the various panels during navigation, and perform some form validation etc. in the background.  I need this server side functionality. 

I would like the Radwindow to resize the height automatically in each Panel of the wizard (to reflect the content in that panel) and to remain centred in the browser.  When I first open the Radwindow it autosizes to the content in the first Panel.  However when I click the 'next' button to show the second content panel in the wizard, the height remains stuck at the height of the first Panel - it doesn't resize to the new content height of the second panel.

I have searched around but have not found a similar scenario to auto resize the Radwindow in a wizard Panel navigation.  Any ideas?

The Telerik controls are Q3 2010 and it's ASP.NET 3.5. Thanks in advance.

Cheers

Kevin

P.S. I have also added a Div, with a width, in the Radwindow ContentTemplate as it doesn't resize properly without this - is there a more elegant solution so that I can remove this Div ideally?  As I said I want to keep theRadwindow width constant - just vary height.

Secondly can I generally use RadAjaxpanel instead of asp:panel in pages?  Is there a benefit or overhead to this? Sorry for all the questions but am new to these controls :)

Dear Sir:
   I have a radgrid with paging for search result, when the user search a large number of record and it take long time to retrieve the data from the stored procedue . In fact, the user normally just look at the first few page in the grid only but they still have suffer the time for get the whole result set from the database. is there anyway/sample to retrieve the record by page and how can i handle the sorting and filtering?

Hello,
I have a table colulmn which contains some IDs. And I have a List<something> which contains reference values for those IDs. Is there a simple way to display those values in the grid column?
It's not possible to use data relations and so on, and the only way to get data is the way described above. And it's not possible to use a ComboBox to display data. I tried to create a template column and put the label there but this would take very much time when combination of large lists and tables is used. Is there a way to do that faster?

Here is what I do in template:

public override void InstantiateIn(Control container)
        {
            Label lbl = new Label();
            lbl.DataBinding += label_DataBinding;
            container.Controls.Add(lbl);
}        
 
        void label_DataBinding(object sender, System.EventArgs e)
        {
            Label lbl = (Label)sender; 
            GridDataItem dataItem = lbl.NamingContainer as GridDataItem;
            DataRowView drv = (DataRowView)dataItem.DataItem;
            RefItem item = Item.refdef.ItemsFlat.Find(m => m.Id == drv[Item.user_name].ToGuid());
            if (item == null)
            {
                lbl.Text = "";
                return;
            }
            lbl.Text = item.Caption;
        }

I want to display an error message in the grid if some operation has failed  (update, delete, etc)
Ive followed an example suggested in the forums, but it doesnt work


gridMessage is supplied a value when something fails, I then rebind the grid

there IS a value in gridMessage when the NeedDataSource is fired, but the error message never gets displayed.
Anyone see what Im doing wrong here ?

Hi,

My aspx page has radgrid and a dropdownlist. I want to populate this dropdownlist based on the value captured from a cell on selecting a single radgrid row.

I have set AllowMultiRowSelection ="false"  and on clientsettings <Selecting AllowRowSelect="True"></Selecting>.

How can I do this?

Or if am using <ClientEvents OnRowSelected="RowSelected" /> and call some javascript I can get the cell value. How will I make use of this to populate the dropdown. The dropdown population is in codebehind.

Thanks,

I would like to use RadEditor to edit content in a CMS.

Of course I want WYSIWYG editing using the same style sheet that I use in the website.

From what I have read in the forums and documentation it seems that I need to create a second style sheet just for RadEditor to use.

In my CMS system the dynamic content is in a specific container, so I hoped I could just specify the ID or class name of the container and RadEditor could use the website style sheet but this does not appear to be possible. (something like CKEDITOR's bodyClass or bodyId)

My other option, which I have used with other editors, is to make the CSS classes that are used in the content area the default for that HTML tag. For example, if all hyperlinks in the content area are to be red then that is the default for the "A" tag and if I want any other colour outside of the content area then I apply a class name to it. This method works with RadEditor except it ruins the display of toolbars and dialogs if some attributes are changed, for example LI tags. Unfortunately the RadEditor style sheet for toolbars and dialogs don't reset a lot of CSS attributes.

So my question is, is there a way of using RadEditor in this circumstance, without having to create a second style sheet and have to maintain two style sheets?

Hi,
With the help of the posts in  http://www.telerik.com/community/forums/aspnet/grid/72051-radgrid-print.aspx#1532370 I could print the entire contents of radgrid in Internet Explorer and mozilla .But  I am not able to print the radgrid of certain web pages of the application  in same version of   mozilla while able to do that in internet explorer.For those pages, the below function PrintRadGrid returns null for $find(radGridId).

For the non-working pages , if i put a alert  as the first line of the function PrintRadGrid , then it is working

Could any body please explain why this happens and  how to make it working ...

function getOuterHTML(obj) {
            if (typeof (obj.outerHTML) == "undefined") {
                var divWrapper = document.createElement("div");
                var copyOb = obj.cloneNode(true);
                divWrapper.appendChild(copyOb);
                return divWrapper.innerHTML
            }
            else
                return obj.outerHTML;
        }

        function PrintRadGrid(radGridId) {

            var radGrid = $find(radGridId);
            var previewWnd = window.open('about:blank', '', '', false);
            var sh = '<%# ClientScript.GetWebResourceUrl(grdName.GetType(),String.Format("Telerik.Web.UI.Skins.{0}.Grid.{0}.css",grdName.Skin)) %>';
            var styleStr = "<html><head><link href = '" + sh + "' rel='stylesheet' type='text/css'></link></head>";
            var htmlcontent = styleStr + "<body>" + getOuterHTML(radGrid.get_element().parentNode) + "</body></html>";
            previewWnd.document.open();
            previewWnd.document.write(htmlcontent);
            previewWnd.document.close();
            previewWnd.print();
            previewWnd.close();

            radGrid.get_masterTableView().fireCommand("EnablePaging", "");
        } 

And in code behind

 RadPnl.ResponseScripts.Add("PrintRadGrid('" + grdNmae.ClientID + "')");

Thanks
