Hi,

Does RadGrid has built-in Database Pagination in addition to the standard Grid UI Pagination?

For example:

In RadGrid standard Page UI Pagination, if you have page size of 25, when the data source is bound then the whole dataset (e.g. 500 member records) is retrieved from the database, but only renders the first 25 records. When the user clicks to go to page 2 the query is run to get the 500 records again and the telerik control will then render the next batch of 25 records in order. Does RadGrid has built-in Database Pagination in addition to the standard Grid UI Pagination that can limit the records retrieved from the database to, say 100 records rather than retrieving 500 records?

I have successfully been able to hide items from the context menu.  Is it possible to remove the separator bars that also appear in the menu?  Also I am struggling to be able to add my own items.  I have seen the examples in c#, however these do not translate well to vb.  Below is the code I am using to hide the items.  It would be much appreciated if someone could show me how to add new items.  Once added I would also need to know how to capture the fired event when the menu item is clicked.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
        AddHandler RadGrid1.HeaderContextMenu.ItemCreated, AddressOf Me.HeaderContextMenu_ItemCreated
 
     ...
End Sub
 
Private Sub HeaderContextMenu_ItemCreated(ByVal sender As Object, ByVal e As RadMenuEventArgs)
        Select Case (e.Item.Text)
            Case "Clear Sorting"
                e.Item.Visible = False
            Case "Sort Ascending"
                e.Item.Visible = False
            Case "Sort Descending"
                e.Item.Visible = False
        End Select
End Sub

Hi,

Beside data binding, is there any way to create a task programmatically with code?

Hi

In below link, we can see combo-box with  checkbox.

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx

When Page load i will use loop to mark selected items like below

RadComboBoxItem item = ComboBox.FindItemByValue(myValue);
 if (item != null)
 {          item.Checked = true;          }

My Requirement:

Use ComboBox - Load on Demand Modes and use web service to load data

When Page load, how to show items initially (if it is a web service call)?

Can we do this? as in my project, i have userlist in drop down as webservice (normal combo box) and i need to change with combobox with checkbox functionality

I tried the following solution but unfortunately, only the visible rows - displayed at the top of the grid - are printed, not those that you see on the screen after scrolling down. AutoGenerateColumns and AllowPaging are set to false.

http://www.telerik.com/community/code-library/aspnet-ajax/grid/print-radgrid-contents.aspx

function PrintRadGrid() 
    var previewWnd = window.open('about:blank', '', '', false); 
    var sh = '<%= ClientScript.GetWebResourceUrl(radGrid1.GetType(),String.Format("Telerik.Web.UI.Skins.{0}.Grid.{0}.css",radGrid1.Skin)) %>'
    var styleStr = "<html><head><link href = '" + sh + "' rel='stylesheet' type='text/css'></link></head>"; 
    var htmlcontent = styleStr + "<body>" + $find('<%= radGrid1.ClientID %>').get_element().outerHTML + "</body></html>"; 
    previewWnd.document.open(); 
    previewWnd.document.write(htmlcontent); 
    previewWnd.document.close(); 
    previewWnd.print(); 
    previewWnd.close(); 


I'm using Visual Studio 2008 / .Net 3.5 along with Telerik RadControls for ASP.NET AJAX 2009.3.1103.35

Any thoughts?

Thanks

but, the editor is not loading the fonts in the iframe. Can anyone assist? Thank you.

Hi,

We are using the full featured RAD Editor for MOSS for one of our clients who want to use "Form element". It seems to work fine, except that it does not save everything. We can add a text input and then add a name attribut to it, but when we check in the page the attribute is removed (and we need to be able to add the name attribute). I think it might be Sharepoint who validates the html code and removes it somehow(?), but how should we go around this? Is "Form element" not suppose to work in RAD editor for MOSS (even though you can add it)?

For now we have added a javascript, setting the name attribute to the same as the id attribute (that we can save with the page). But this does not work for radiobuttons.

Best regards
Maria

I have an ASP.Net with a RadGrid.  VB.Net is the code-behind.

In the RadGrid, one of the columns is a hyperlink column.  When the user clicks on that column, it brings them to an ASP.Net page to display the details of the item they clicked on.

When the user clicks on the hyperlink column, is there a way to show the AjaxLoadingPanel on the RadGrid since loading the page with the details may take more than a few seconds?

Please help!

Thanks!

Sincerely,

Keith Jackson

I have a legacy application that uses RadScheduler. It looks like the version it is built with is 2012.3.1206.40.

We recently discovered a problem with the context menu on mobile devices. We have a right-click menu set up that displays some options when the application runs in a desktop browser. This works well on the desktop but not on mobile devices. 

A long tap on a mobile device in theory should activate the same menu but it does not appear. Is there anything I should or could do to make it work on mobile? I was expecting it to just work. 

I understand I may need to update the control but I'm unsure on how to go about doing that. Can someone point me in the right direction? Thanks!

I implemented paste from Excel based on info from this forum. With latest version of RadGrid it does not work any longer. I am having trouble to fix it. Can you help, please?

function pasteFromExcel() {

            var ua = window.navigator.userAgent;
            var msie = ua.indexOf("MSIE ");

            if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
                //continue for IE
            }
            else {
                jInfo("Paste from Excel works only in IE (due security policies of other browsers)","INFO")
            }

            if (!lastFocused) return;
            var clipData = window.clipboardData.getData('Text');
            var crlf = String.fromCharCode(13) + String.fromCharCode(10);
            var table = clipData.split(crlf);
            for (var tRow = 0; tRow < table.length - 1; tRow++)
                table[tRow] = table[tRow].split(String.fromCharCode(9));
            Array.remove(table, table[table.length - 1]);
            fillTable(table);

            $('#<%= lbtnSaveMarketAccessArea.ClientID %>').attr("class", "button3D_Yellow");
        }

        function fillTable(table) {
            var pCell = lastFocused.parentNode;
            var pRow = pCell.parentNode;
            var pBody = pRow.parentNode;
            var maxRows = pBody.rows.length;
            var maxCols = pRow.cells.length;

            for (var row = 0; row < table.length; row++) {
                for (var col = 0; col < table[row].length; col++) {
                    var cCellIndex = pCell.cellIndex + col;
                    var cRowIndex = pRow.sectionRowIndex + row;

                    if (cRowIndex < maxRows && cCellIndex < maxCols) {
                        var cCell = pBody.rows[cRowIndex].cells[cCellIndex];
                        var pInput = cCell.getElementsByTagName("input")[0];

                        pInput.style.backgroundColor = "#F7FAFF";
                        pInput.value = table[row][col];
                    }
                }
            }
        }
