Adding SpecialDays to the rad calader dinamiccally.

I am trying to add special days dynamically, I have set the template of the special day via aspx, and I am trying to assign it the dates with code on DayRender event. Thing is, it's not happening.

The aspx code goes:

<telerik:DayTemplate ID="DisableTemplate" runat="server">
                <Content>
                    <div class="rcTemplate rcDayDisabled">
                    </div>
                </Content>
            </telerik:DayTemplate>
the css:

.RadCalendar_Special .rcRow .rcDayDisabled
{
   background:0 0 no-repeat url(Disabled.gif);
}

the c#:

protected void RadCalendar1_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
        {
            if (e.Day.Date < DateTime.Now.Date)
            {
                RadCalendarDay RadDay = new RadCalendarDay();
                RadDay.TemplateID = "DisableTemplate";
                RadDay.Date = e.Day.Date;
                e.Cell.CssClass = "rcDayDisabled";
                RadCalendar1.SpecialDays.Add(RadDay);
                }
}
also I noticed that without the property: Repeatable="DayInMonth" filled the special day will not appear... is there a solution to these problems:

InPlace mode complains

Hi,
I was wondering whether there is a true InPlace editing in the RadGrid.
I explain: I've looked at your documentation and I've tried to set the EditMode="InPlace" and nothing happened.
Then I digged more on the subject and I found out that I should manage the double click event of the grid.
I copied the example I found in the documentation and it worked, but, sadly, I noticed it is performing a partial update of the page (don't like).
Then I looked in your online examples and found this:
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/clienteditbatchupdates/defaultcs.aspx
Perfect: it is not performing partial updates, but then I look at the page code and I see two hundred lines of javascript codes where you on the basis of the column name extract the info necessary to update the UI.

The question is: is all of this necessary? Is there not any built in way (without writing tons of JS or performing postbacks) to perform in place editing?

Best regards, Andrea Pirola

Dock style properties

Is there a way to turn off all the font styles that a raddock generates? I have the following configuration on my page:

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

<asp:Label ID="LabelAdmin" runat="server" Text="" />

<telerik:RadDockZone ID="RadDockZoneContentBlock1" runat="server" MinHeight="50px" MinWidth="100px" BorderStyle="None">

<telerik:RadDock ID="RadDockContentBlock1" runat="server" DockHandle="None" DefaultCommands="None" OnClientInitialize="SetHandleDock" DockMode="Docked">

<ContentTemplate>

<div id="Handle_ctl00_ContentPlaceHolder1_RadDockContentBlock1" style="cursor: move;">

<uc1:ContentBlock ID="ContentBlock1" ContentID="1" runat="server" />

</div>

</ContentTemplate>

</telerik:RadDock>

</telerik:RadDockZone>

</asp:Content>

I have attached 2 images to this, the "correct style.png" is how it is supposed to look on the page. The "wrong style.png" is how it looks when i create the same page using the above layout. If I move the content blocks outside the raddock it looks just fine, as well I used firebug and turned of some skins and styles on the raddock and the preview firebug shows looked correct as well. I have tried turning on and off pretty much every property I can find for raddocks but nothing fixes the problem.

<td style="height: 72px">

</telerik:RadGrid>

<br />

</td>

</tr>

<%-- </div>--%>

</ItemTemplate>

</MasterTableView>

</telerik:RadGrid>

Everthing works fine, i am able to export both the grids into a single excel.
but i had a question in this i have set page size as 100 as you can see so when i am exporting to excel only the 100 items are getting exported (which is right).
this is my code behind method for exporting

RadGrid radGrid = lbl_txt.Text == "All RadGrids" ? radGridWrapper : (RadGrid)radGridWrapper.Items[0].FindControl(lbl_txt.Text);

//html.Visible = false;

if (radGrid.Items.Count == 0)

{

Page.ClientScript.RegisterStartupScript(base.GetType(), "Alert", GC.Message("No records found"));

return;

}

if (isExcelExport = true)

{

gridcaption = "<b style='color: blue; text-align: left;'>Effort Analysis Report </b>";

if (CheckBox4.Checked == true)

{

gridcaption += "<BR/>" + "<b>Process : </b>" + ddlprocess.SelectedItem.Text + " " + "|" + " " + "<b>Group : </b> " + ddlGroupby.SelectedItem.Text + " " + "|" + " " + "<b>From Date :</b>" + txtFromDate.Text + " " + "|" + " " + "<b>To Date :</b>" + txtToDate.Text;

}

radGrid.MasterTableView.Caption = gridcaption;

radGrid.ExportSettings.FileName = "EffortAnalysis_" + "_from_" + txtFromDate.Text + "_to_" + txtToDate.Text;

radGrid.ExportSettings.OpenInNewWindow = true;

//radGrid.ExportSettings.IgnorePaging = true;

//radGrid.ExportSettings.ExportOnlyData = true;

gridBind();

radGrid.MasterTableView.ExportToExcel();

so if in this method i add in export settings as ignore paging i am getting an error saying the below message
Object reference not set to an instance of an object.

can any of you guys tell me how i can get over this speed bump
