How to input data without triggering OnClientChange event

Hello,

I am trying to create a spreadsheet where users can input data to a formatted sheet. The changes are written to database and then the spreadsheet values are changed according to data inputted. But writing data with Javascript triggers the event again. Locking the OnClientChange method is one way I accomplished this, but rapid changes don't get recognized and are ignored. Is there a better way of fixing this issue?

Thanks for any help in advance :D

Disable value changes when dragging cells

How do I stop values from changing when dragging cells. In the provided example, the values iterate trough day abbreviations (the days are in Lithuanian language. Translations of the day abbreviations would be: friday, saturday, sunday, monday, tuesday). What is weird is that I can't replicate it in English or Russian.

Thanks for any help provided! :D

Radgrid/WebResource JS Exceptions

I have a very simple ASP.net web form with a couple of data pickers, a button and a radGrid. When I initially load the page the grid is not populated and is dependant on both date pickers having selected values. When I click the "Refresh" button to set the radGrid datasource (the result of a stored procedure with two parameters), I noticed that none of the grid filters worked. Upon further investigation I see that there are a couple of uncaught errors (see the attached image).

I am using version 2020.3.1021 of the ASP.net controls so there isn't any outstanding updates. Other grids work as expected.

Can you advise?

telerik:RadEditor - undefined error when clicking on controls

We're using a telerik:RadEditor and have just updated to .Net 4.7.2.

When we click on some of the controls, e.g. the "strip formatting" control, then we sometimes (not always) get the following error shown in the Browser's console "Cannot read property 'trim' of undefined".

We're running version 2014.1.403.35 of the Telerik.Web.UI. We know that there are newer versions available but don't want to have to upgrade if this is not required.

Two errors are as follows:

[Solved] loading.gif not displayed in RadAjaxLoadingPanel with Internet Explorer

Hi, I have a RadAjaxLoadingPanel which has a gif image loaded by GetWebResourceUrl function. When I make an ajax postback the loading panel is displayed (a gray panel covering all the controls in the page) but the gif inside the loading panel is not displayed. This only happens with Internet Explorer 7-8. It works fine with Firefox, Safari and Chrome.

    
                <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel" runat="server" BackColor="#E0E0E0" 
        
                    Transparency="20"> 
        
                    <table style="width: 100%; height: 100%;"> 
        
                        <tr style="height: 100%;"> 
        
                            <td style="width: 100%; text-align: center; vertical-align: middle;">                
        
                                <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' 
        
                                    style="border-right: 0px; border-left: 0px; border-top: 0px; border-bottom: 0px;" /> 
        
                            </td> 
        
                        </tr> 
        
                    </table> 
        
                </telerik:RadAjaxLoadingPanel> 
        
                <telerik:RadAjaxPanel ID="RadAjaxPanel" runat="server" LoadingPanelID="RadAjaxLoadingPanel"> 
        
                 <div style="width:500px; height:500px"> 
        
                 </div> 
        
                </telerik:RadAjaxPanel>

I have all the necessary web.config entries

<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

PS: When I check the telerik web pages (such as http://demos.telerik.com/aspnet-ajax/ajax/examples/loadingpanel/loadingimages/defaultcs.aspx) running with RadAjaxLoadingPanel my internet explorer browser successfully shows the gif images. So I think this is not related to internet explorer configuration.

Thank you...

Radgrid Export after auto filter issue

I am having an issue when attempting to export a radgrid to excel after utilizing the filters in the auto filter.

Before applying the filter, it works perfectly and exports the data to excel. After applying the filter, the export does not work and appears to simply rebind the grid; however this time the filter rows are removed.

The data for the grid is populated using the NeedDataSource event.

Through searching the forums, I have found that I should probably be using the ExcelML, but this yields the same results.

protected void radimgbtnExcelExport_Click(object sender, ImageButtonClickEventArgs e)

{

radgridUsageRatio.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;

radgridUsageRatio.ExportSettings.IgnorePaging = true;

radgridUsageRatio.ExportSettings.ExportOnlyData = true;

radgridUsageRatio.ExportSettings.OpenInNewWindow = true;

radgridUsageRatio.MasterTableView.Columns[0].Visible = false; //remove command column

radgridUsageRatio.MasterTableView.Columns[1].Visible = false; //remove command column

radgridUsageRatio.MasterTableView.ExportToExcel();

}

Any help anyone can provide would be extremely helpful

Trying to impliment font awesome

I need to globally set a class on the combobox dropdown arrow

...but there's no public css property to do that right? There's one for the control, the dropdown list, the input, and the label....but no button.

So I'm looking for a skinnable property, not a workaround to inherit from he control or parse the dom with jquery, or do any codebehind. There's too many comobs to just go around updating all the code in every page (hoping to just leverage a .skin file)

Yes, no?...could you add one?

RadNumericTextBox in iPad

Hello

Using RadNumericTextBox in a mobile website doesn't pop up numeric keyboard in iPad. We're developing a website where the user has to enter a lot of numeric information and it has to choose the numeric pad each time it enters a new numeric field.

I know that using RadTextBox and Inputtype solves this problem, but I mainly use RadNumericTextBox because it allows to specified validation like min and max values to each field.

Thanks in advanced
