ListView Pagination Lost in Cross Page Postback
Hi,
I am post form data from, say, source.aspx to destination.aspx page. The source.aspx page has some checkboxes which are used in a SQL query in the destination.aspx page. For example,

 if (Request.Form["color_spice"] != null) { WhereClause += " OR ado_products_fabrics.color = 'spice'"; }

The first time the destination page loads the RadListView shows the pagination fine. However, clicking on the RadDataPager under the RadListView causes a postback where the source.aspx page's Form data are lost. I have tried using PreviousPage.FindControl() method but that too does not resolve in the pagination's postback.

So what can I do? I don't want to use Session variables--there are going to be dozens of controls from the source.aspx page passing values to destination.aspx page. Cookies too will be too much to track then?

Below are the code-fragments for the .aspx and the .cs files.

Thanks!

Appointment not showing up on scheduler screen
We have a requirement to show scheduled tasks for each individual. The tasks will be edited using a different mechanism, not via the scheduler, but we'd like to display them on a scheduler screen.

The data is loading, but the text on the calendar is blank; the attached screenshot shows how it looks, with the tooltip visible but no text on the calendar. here's the definition.

<telerik:RadScheduler ID="RadSchedulerCommitments" runat="server" AllowDelete="False"
AllowEdit="False" AllowInsert="False" DataSourceID="dsCommitments" SelectedView="MonthView"
DataStartField="DueDate" DataEndField="DueDate"
DataKeyField="CommitmentID" DataSubjectField="CommitmentItem"
OverflowBehavior="Expand" ReadOnly="True" ShowHoursColumn="True"
ShowViewTabs="False" >
</telerik:RadScheduler>

Any idea what's wrong?

[Solved] RadGrid dynamic creation with ObjectDataSource
I'm trying to create a radgrid dynamically and bind it to a dynamically created ObjectDataSource, but grid is always empty (maxRows is 0 in GetData method).  What did I do  wrong?

Next question is this._grid.DataBind() in OnLoad method. Is it necessary? After it grid will show data, but paging will not work (other pages will by empty).

Standard GridView seems to be working correctly.

Here is full sources

using System;
using System.ComponentModel;
using System.Data;
using System.Globalization;
using System.Web.UI;

[Solved] Accessing name of control inside of Dock
Hi Telerik,

I have a dynamically created Dock and its content is a chart. I load the content for the dock like so:

private void LoadDockContent(RadDock dock)
{
    System.Web.UI.Control ctrl = Page.LoadControl("PowerUsage.ascx");
    dock.ContentContainer.Controls.Add(ctrl);
}

I need to be able to access the name of the control ClientSide.

I suspect it's something like this, but I'm not quite on:

<script type="text/javascript">
    function OnClientInitialize(dock, args) {
        var content = dock.get_contentContainer();
        var control = $telerik.isIE ? content.childNodes[0].innerHTML : content.childNodes[1].innerHTML;
        alert(control);
    }
</script>

The alert displays a dump of all the HTML in the dock. This does include the control I am looking for, but there would be some extremely heavy parsing necessary to isolate the string that I want from the HTML. I've attached to this post "html.png" which is the output of the alert.

If I could just get the img id instead of all the HTML I would be happier, but I would be happiest if I could capture the control name without any parsing, obviously. Ultimately, my goal is to utilize some jQuery to resize the chart control stored on the RadDock. Just to make sure I'm not headed down a dark path, I would also just like to get a quick, "Yep. That should work!" from you guys.

<script type="text/javascript">
    jQuery(function($) {
            $(window).wresize(SetPageChartSizes<%= Chart.ClientID %>);
            SetPageChartSizes<%= Chart.ClientID %>();
        });
                 
        function SetPageChartSizes<%= Chart.ClientID %>() {
            document.getElementById('<%= hfChartWidth.ClientID %>').value = (document.getElementById('<%= updatePanel.ClientID %>').offsetWidth - 4);
            <%=Page.GetPostBackEventReference(btnHidden_Charts)%>;
    }
</script>

So, this code isn't 100% relevant to what I've got going on, yet. This function waits for the window to be resized and then resizes Chart based on the new window size. I am going to rewrite this so that whenever the size of the Dock changes the content it controls (a chart) will resize to fill the size of the dock. Chart doesn't just exist on the page, though. I have to get a handle on that -- which means I need to get the control name from the Dock.

Let me know if anything here is unclear.

Thanks,

Sean

Issue with Radtooltip in IE8
Hi,

I'm using the example posted on the following link
http://demos.telerik.com/aspnet-ajax/tooltip/examples/tooltipcalendar/defaultcs.aspx


When I try to click on a date associated with a tooltip in IE8 (8.0.6001.18702), I get an unknown runtime error in ScriptResource.axd
The page works fine in Firefox, Chrome and Opera..

Any Ideas??

Source Code for page containing the calendar
public partial class rcalendar : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {    }
    protected void RadCalendar1_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
    {
        int ID = e.Day.Date.Day;
         if (ID == 3 || ID == 5 || ID == 14)
        {
            TableCell cell = e.Cell;
            cell.Attributes.Add("onclick", "ShowToolTip(this);");
            cell.Attributes.Add("id", "Calendar_" + ID.ToString());
        }
     }
    protected void RadToolTipManager1_AjaxUpdate(object sender, Telerik.Web.UI.ToolTipUpdateEventArgs e)
    {
        CalendarTT cdrTTobj = (CalendarTT)this.LoadControl("CalendarTT.ascx");
         cdrTTobj.Dateid = int.Parse(e.Value);
        cdrTTobj.ID = Guid.NewGuid().ToString();
         e.UpdatePanel.ContentTemplateContainer.Controls.Add(cdrTTobj);
    }
