Hi All,

I have an all code-behind solution and noticed an interesting quirk. I have a grid with hierarchy. Whenever I go to export it to Excel I receive a blank row under each row with content. I found the following link that points out my HiearchyLoadMode as being the culprit, and sure enough, if I switch from Client to ServerOnDemand the blank rows go away.

Unfortunately, I am using the Export to Excel functionality along with this link that pertains to hiding the expand/collapse icons when there are no records, and setting it to something other than Client hides all expand/collapse icons.

Does anyone one have any ideas how I can have both?

Thanks,
Mark

[Solved] Disable Button on CheckBox unchecked

I am using the code below to force customers to select item from a Grid CheckBox

function GetCheckedItemCountbtnClick() {

var checkedcount = 0;

var grid = $find("<%=gvSummary.ClientID %>");

for (var i = 0; i < grid.get_masterTableView().get_dataItems().length; i++) {

var objchkbox = grid.get_masterTableView().get_dataItems()[i].findElement("CheckBoxStatus");

if (objchkbox.checked) {

checkedcount++;

}

//}

if (checkedcount > 8) {

objchkbox.checked = false;

alert("Please select only 8 item");

return false;

}

if (checkedcount == 0) {

alert("Please Check at least one CheckBox");

return false;

}

}





I have a Button I want to disable when the 'checkedcount ==0' unless an item is checked

<asp:Button ID="btnPrint" runat="server" Font-Size="X-Small" OnClick="btnPrint_Click"
                            Text="Print" ToolTip="Create a  report..." />


Nothing seems to work for me. Any idea will be appreciated.

Extra space after resizing browser window

hi support,

I'm using RadSplitter and RadPane to build my page (see page markup as below). The page has min-height and min-width setup in order to show scrollbar(s) whenever the size of browser window hits the minimum height/width. The problem i have is an extra space appears at the bottom of page (under the most outer RadSplitter) after resizing the browser window to the min-height and this ONLY happens in IE8 and Safari 5.0 + (images attached), the page itself is quite simple and i don't know it's because i'm doing something wrong or related to telerik control. Please help and very appreciated!

Hi,

In my page i have 3 date picker, but only 2 are enable. The last one of those is disable and only have a selectedDate when the first 2 one have a date selected. Everything is set from client side on OnDateSelected event.

But i try to get the date from my last datepicker in server side it always return me a null value.

I try to enable the control and it work fine i was able to get the selecteddate. But i can't keep the control enable i absolutly need it disable.

Here is the code i'm using to validate my selecteddate:

    
                    <script language="javascript" type="text/javascript">  
        
                        var datePickerAttributionSetter;

                        {  
        
                            var datePickerAttribution = $find("<%= RadDatePickerAttribution.ClientID %>");  
        
                            var datePickerTheoricalExam = $find("<%= RadDatePickerTheroicExam.ClientID %>");  
        
                            var datePickerPracticalExam = $find("<%= RadDatePickerPracticalExam.ClientID %>");

Sys.Extended.UI - Framework 4.0 Error

I've seen some posts in here about this issue but none seem to be answered.

I'm developing an ASP.Net Website using the AjaxControlToolkit - September 2013 release along with the Q2 2013 SP1 release of the Telerik.Web.UI controls.

I have a RadScriptManager on my page:
<telerik:RadScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>

I also have an AjaxToolkit:ModalPopupExtender that, when the application is ran, throws the following Javascript error:
Microsoft JScript runtime error: 'Sys.Extended.UI' is null or not an object

If I replace my RadScriptManager with an AjaxToolkit:ToolkitScriptManager, it works fine.

I believe this issue is because in the 3.5 and up frameworks for the AjaxControlToolkit, the namespace changed from AjaxControlToolkit to Sys.Extended.UI.

I just need to know how to make my RadScriptManager work with the latest AjaxControlToolkit so I don't get this error.

Thanks!

Hi

We are using RadEdior control with following markup
<telerik:RadEditor ID="reNotes" runat="server" ClientIDMode="Static"
Language="en-US"
TabIndex="72"
EditModes="Design"
Height="150px"

CssClass="defaultText" >
</telerik:RadEditor>

.defaultText
{
padding-top: 0px;
text-align:left;
}

Default text on the page is Arial 11px. When User set font style to Arial, "radeditor.content" property does not include font -family name into the style. Please see the attached document.
We would like to get the default font-family name too from "radeditor.content". Can you please suggest how can I achieve this?

Thank you.
