How-To Enable Partial Rendering On Grid?
I have a RADGrid on my page. But when the user clicks any of the control in the grid, Page Forward/Back, Page Number, PageSize, Refresh, Checkbox Row Selector, etc... The entire page refreshes.  I would like to have just the Grid itself refresh.  I looking online, but I can't seem to find the information to make it all click.

I am using DNN 6, and I manually registered the RADAJAXManager on the page. I saw there was an EnableAJAX setting, but then later found that it was depreciated in the newer Telerik controls. So then I tried programatically adding the AJAX Settings with AddAjaxSetting(objMyRADGrid, objMyRADGrid), but nothing happens. I am guessing I am doing something wrong, or I am looking entirely in the wrong place.

Any clues or suggestions?

Pass value via linkbutton
Current project requires that I pass a value that someone typed in via a RadDateInput textbox to the radWindow that will launch when a user clicks on the link button.  Maybe I am getting confused with the controls and would appreciate some direction.  Below is my code.
<script type="text/javascript">
    //<![CDATA[
    function openRadWin() {
        radopen("ManageFS.aspx?cycle_date=" + radDateInput1, "RadWindow1");
    }
    //]]>                                                                       
</script>
When a user clicks btnAddStmt it will launch the radWindow and I would like to pass the value.  What I also would like to do is validate that _new_period is not blank otherwise there is no need to pop-up the window.  Can't seem to have it perform validation client-side and still have things work.
<td style="text-align: center;">
    New statement cycle date <strong>(mm/dd/yyyy)</strong>:
         
    <telerik:RadDateInput ID="_new_period" runat="server" Width="100px"
        InvalidStyleDuration="100" CssClass="InputText" DateFormat="MM/dd/yyyy"
        DisplayDateFormat="MM/dd/yyyy">
    </telerik:RadDateInput>
</td>
<td style="text-align: center;" class="side">
    <asp:LinkButton ID="btnAddStmt" runat="server" Visible="false">Add Statement</asp:LinkButton>
</td>
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
           If Session("site_member_type") = 1 Then
                btnAddStmt.Visible = True
                Me.btnAddStmt.Attributes.Add("onclick", "openRadWin(); return false;")
                Me.pnlHideViews.Visible = True
            End If
end sub

Tabstrip with Radeditor
Hi,

I've a scenario of 5 radtabs. In one of the radtabs I have one Radeditor.

I've noticed that when I have a large amount of text inserted in the Radeditor, when I change from one tab to another tab, it takes a long time (about 2 seconds) to change. The strange is that I don't have any postback when changing tabs, this should run smooth. I even tried to put the two radeditors outside the tabs and de behaviour is the same.

The text that is content in the radeditor is the next one:
<table width="92%" cellspacing="0" cellpadding="0" border="0"> <tbody>        <tr>            <td valign="top">            <p><strong>Description</strong></p>            </td>           
<td valign="top">            <p><strong>2012</strong></p>            </td>            <td valign="top">            <p><strong>2013</strong></p>            </td>            <td valign="top">            <p><strong>2014</strong></p>            </td>            <td valign="top">            <p><strong>2015</strong></p>            </td>            <td valign="top">            <p><strong>2016</strong></p>            </td>        </tr>        <tr>            <td valign="top">            <p><strong>Description</strong></p>            </td>            <td valign="top">            <p><strong> </strong></p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>        </tr>        <tr>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>            <td valign="top">            <p> </p>            </td>        </tr>        <tr>            <td valign="top">            <p><strong>A –Publications</strong></p>            </td>

The radeditor definition is:

<telerik:RadEditor ID="3" runat="server" Width="100%" Height="200px"  StripFormattingOptions="AllExceptNewLines">          </telerik:RadEditor>



I made an experiment and replaced the radeditor for labels and I don't get any performance issue. It seems some client processing on radeditor is bringing the poor performance.

Can anybody help, please?

'stop running the script' in IE

 

 

Hi Team,

I have the below treeview and uses 'Load On Demand' and for certian nodes it has around 5000 child nodes and are throwing the javascript error 'stop running the script'. Below are what I tried.

1. In the NodeExpand event, I changed the expand mode to 'ServerSide', it worked fine. But I need AJAX.
2. I tried setting ScriptMode="Release" but didn't work.
3. I tried PersistLoadOnDemandNodes='false' and it worked. But I want to use server side events.

Regards,
Gijo Joseph.

 

<telerik:RadTreeView ID="RadTreeView" runat="server" EnableDragAndDrop="true" 
onnodedatabound="RadTreeView_NodeDataBound"
onnodeexpand="RadTreeView_NodeExpand"> 
</telerik:RadTreeView>

 

 

 

 

protected void RadTreeView_NodeExpand(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
  List<Node> ltChilNodes = GetListofChildNodes();
  foreach (Node node in ltChilNodes)
  {
    RadTreeNode onDemandNode = new RadTreeNode(node.Name);
    onDemandNode.Attributes.Add("Attr1", node.Attr1);
    onDemandNode.Attributes.Add("Attr2", node.Attr2);
    onDemandNode.Attributes.Add("Attr3", node.Attr3);
    onDemandNode.Attributes.Add("Attr4", node.Attr4);
    onDemandNode.Attributes.Add("Attr5", node.Attr5);
  
    onDemandNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;
  
    e.Node.Nodes.Add(onDemandNode);
 }
  
}

Refreshing RadGrid after downloading file via ashx
I have a grid with a column that shows whether a file has been downloaded or not (via an image in a grid column)

When the user clicks the Checkout toolbar button, I call an .ashx file, which downloads the file to the user's desktop and updates the the database that the file's been checked out.  The issue I'm having is that when I try and refresh the grid by calling the grid.rebind method (on either the client or server side), not all the logic in the .ashx file gets executed (well, the database is updated, but the file isn't downloaded).

How can I refresh the grid on the client side after *successfully* calling the ashx method (where successfully means the file is downloaded *and* the database is updated)?

Here's the relevant code:

function CheckOut(){
 
    var isExternal = false;
    var rgGrid = $find("<%= rgAttachmentVersion.ClientID %>");
 
    if ( rgGrid._selectedIndexes[0] == null ) {
        rgGrid = $find("<%= rgExternalAttachment.ClientID %>");
        isExternal = true;
    }
 
    var selectedVersionId;
    if ( isExternal ) {
        selectedVersionId = rgGrid._clientKeyValues[rgGrid._selectedIndexes[0]].ID + "&isExternal=true";
    } else if ( rgGrid._selectedIndexes[0].indexOf(":") > 0 ) {
        selectedVersionId = rgGrid._clientKeyValues[rgGrid._selectedIndexes[0]].ID;
    } else {
        selectedVersionId = rgGrid.MasterTableView.getCellByColumnUniqueName(rgGrid.MasterTableView.get_dataItems()[rgGrid._selectedIndexes[0]], "OpenVersion").innerHTML;
    }
         
    var finalUrl = "~/VersionCheckoutHandler.ashx?id=" + selectedVersionId + "&callback=false" + "&rand=" + Math.random(); // add random number to make sure the browser does nto cache it
    var xhReq = new XMLHttpRequest();
    xhReq.open("GET",$Url.resolve(finalUrl),false);
    xhReq.send(null);
             
    if ( xhReq.responseText == "FILEDOWNLOADERROR" )
    {
        alert("An error has occurred. Please contact your system administrator.");
    }
    else if ( xhReq.responseText == "VERSIONALREADYCHECKEDOUT")
    {
        alert("This version is currently checked out.");
        refreshAttachmentList();
    }
    else if ( xhReq.responseText == "UNABLETOCHECKOUTREMOTEREPOSITORY")
    {
        alert("This version is unable to be checked out from the remote repository.");
    }
    else
    {
        triggerIsPostBack = true;
        window.location = $Url.resolve("~/VersionCheckoutHandler.ashx?id=" + selectedVersionId + "&callback=true");
        triggerIsPostBack = false;       
    }
}


I have a client-side call that rebinds the grid (below) successfully from other methods, but when I call that after calling the CheckOut function, the file isn't saved locally (even though the grid rebinds).

function refreshAttachmentList() {
    try{displayLogoffWarning = false;} catch(ex) {}
    try {
        $find("<%= rgAttachmentVersion.MasterTableView.ClientID %>").fireCommand('<%=RadGrid.RebindGridCommandName %>');
    } catch (ex) { }
    try {
        $find("<%= rgExternalAttachment.MasterTableView.ClientID %>").fireCommand('<%=RadGrid.RebindGridCommandName %>');
    } catch (ex) { }
 
}
