I've read and tried to emulate the tutorials but for the life of me it doesn't seem to be working... I'd be very grateful if someone could point me in the right direction.

I'd like to style the drop down content of my comboboxes, mainly to give me a larger target when using touch in a browser, i.e: larger font and cell size if that needs to be set independantly. Can someone give me a Reader's Digest version of the necessary CSS selectors?
I'm using the default skin btw.

Much obliged for any assistance.

Paul

EDIT:

Solved it by adding " !important " to my CSS

Formdecorator fails on GridDateTimeColumn Filtercolumn with IE8

I have this column in a grid:
<telerik:GridDateTimeColumn DataField="empfangen" HeaderText="Empfangen" SortExpression="empfangen" UniqueName="empfangen" DataType="System.DateTime" ShowFilterIcon="False" ReadOnly="True" AllowFiltering="True" />
and i must disable the filtering calendar -> AllowFiltering="False" with Formdecorator turned on and using IE8.
(no problem with IE7 or 9 or FF)
Error is Javascript error on line 276 of RadFormDecorator.js -> 'r.height=n+"px";'

Versioninfo: Telerik.Web.UI, v.2012.3.1016.40 (Dev) [Download] (UI Language mostly German)

does any other out there have this problem? is it possible to turn of filter for IE8 only?

regards Marcel

can I prevent client side setAttribute

I am adding custom attributes server side and then using them for some basic client side logic.

I am then accessing them on post-back on the server as well. Is there a way to prevent client side setAttribute? Attributes be accessed via setAttribute and be over written, right? Can I prevent this?

Thanks, Marty

Rad Combo box enter Key press issue

Hi,

I am using a Rad combo box with properties

EnableLoadOnDemand ="true"

OnItemsRequested="ddlCode_ItemsRequested"

OnSelectedIndexChanged ="ddlCode_SelectedIndexChanged"

MarkFirstMatch="false"

But if I enter a text which is existing in the combo list and press on enter it will not go to selectedIndexChanged event.

My requirement is if i enter the text and perss on enter key it should go to the selected indexchaned event. and the entered text item should get selected in the combo box.

In the below url i have seen a example when on client key press if "enter Key" is found they invoke serverside button postback event.

http://www.telerik.com/community/forums/aspnet-ajax/combobox/keypress-event-of-radcombo-box.aspx

How we can achieve this for dropdown enter Key press event. to invoke selectedIndex changed event?

thanks

PageViewCreated doesn't fire

Hi all,

I'm having a problem with PageViewCreated either not firing at all or firing too often. My markup is this:

<telerik:RadTabStrip ID="rtsReturns" runat="server" MultiPageID="rmpReturns" OnTabClick="rtsReturns_TabClick">

<Tabs>

<telerik:RadTab runat="server" Text="Current Returns" Value="Current"></telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage id="rmpReturns" runat="server" SelectedIndex="0" Width="400">

<telerik:RadPageView id="pgvwCurrent" runat="server">

<h1>This is where the current returns will go</h1>

</telerik:RadPageView>

</telerik:RadMultiPage>

And my codebehind is:

protected void Page_PreRender(object sender, EventArgs e)

{

if (!IsPostBack)

{

foreach (TrustTaxReturnGroup ttrg in Ctl.FormerTTRGs)

{

RadTab tab1 = new RadTab(ttrg.StartDate.ToString());

tab1.Value = ttrg.StartDate.ToString();

rtsReturns.Tabs.Add(tab1);

RadPageView pg1 = new RadPageView();

pg1.ID = ttrg.StartDate.ToString();

rmpReturns.PageViews.Add(pg1);

}

and

protected void rmpReturns_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

RadTextBox tb = new RadTextBox();

tb.Text = "This should be on the page just created";

tb.ID = e.PageView.ID + "_textbox";

e.PageView.Controls.Add(tb);

}

If I modify the markup to include

OnPageViewCreated="rmpReturns_PageViewCreated"

the PageViewCreated method fires three times every time I click a tab (since there are three tabs being created programatically). But if I don't have that in my markup it never enters that routine at all. I thought maybe it had something to do with the pageviews being created in the PreRender but I moved it to the Page_OnLoad and the results are the same.

I'm sure it's something I'm just not seeing, but I'm just not seeing it. Can anyone out there set me straight? I'd greatly appreciate it.

itemtemplate tooltip not displaying

I am dynamically creating one panel. I am adding multiple comboboxs to it and each should have it's own tooltip.

Only the tooltip for the panel displays. If I remove the panel tooltip the item tooltips display but only after an odd delay.

I can post some code if you like, it this an issue I should be aware of?

Multi Series RadBarChart incorrect x- points

I have a bar chart with multiple series. When I have only one series, the bar shows up on the correct X Point. When I add a second series, the bar will no longer sit on its proper x point.

The images below graphandline.png and 2graphandline.png show the bar chart before and after the second series is added. You will notice that the first graph shows a point after 10/24. When a second series is added, that 10/24 point moves to the left of the 10/23 mark on the x axis. The third chart 3graphandline.png shows the graphs after manually setting the range and steps. As you can see, the x points are sitting between days. This graph is databound with the following code

chartResults.DataManager.ValuesXColumn = "iDate"

chartResults.DataGroupColumn = "sType"

chartResults.PlotArea.XAxis.Appearance.ValueFormat = Styles.ChartValueFormat.ShortDate

chartResults.DataSource = dt

The snippet below is a sample of data being added to the data table. It converts the date to an object, as suggested in the online documentation.

fValue = rdr("sValue").ToString

Dim dDate As DateTime = rdr("dStartDateTime")
Dim oDate As Date = New Date(dDate.Year, dDate.Month, dDate.Day)

Dim oRow As DataRow = dt.NewRow
oRow("fValue") = fValue
oRow("iDate") = oDate.ToOADate()
oRow("sDate") = rdr("dStartDateTime").ToString
oRow("sType") = sDrug
dt.Rows.Add(oRow)

Is there something I am missing, or doing wrong. The goal is to have the x points from series 1 remain on the correct x point when another series is added. Any advice, or suggestions are appreciated.

Many thanks in advance!

BUG with parented comboboxes where children have checkboxes

Hi,

I have drastically simplified my code and cannot figure out a bug that is now happening.

I have a combobox and once values have been selected it goes away and the child gets populated. I have 100s of these and they work fine. Now that I've upgraded to Q3 2012 I am finding that when the child combo box has checkboxes I run into issues.

The combo still works and gets populated with the data but when I click on one of the checkboxes the text doesn't appear in the combo box line

BTW your support page is showing a 403 error...

Basic code is as follows:

<telerik:RadAjaxManager ID="uxRadAjaxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="uxClient">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="uxPortfolio" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadComboBox ID="uxClient" Runat="server" AllowCustomText="true" CssClass="halfWidthComboBox"

onclientselectedindexchanging="LoadClientChildren" onitemsrequested="uxClient_ItemsRequested" MarkFirstMatch="True"></telerik:RadComboBox>

<br />
