[Solved] Wrapping text in an Excel cell via GridExcelBuilder

When using the GridExcelBuilder to add and format a new row when exporting from the RadGrid, is there a way to set a cell within the row to wrap text? This would give the same effect as if you invoked the "Alignment > Text Control > Wrap Text" option in the Format Cells property sheet in Excel. Hopefully the code snippet below will give an idea of what I'm trying to do.

    
            protected void Grid_ExcelMLExportRowCreated ( object source, Telerik.Web.UI.GridExcelBuilder.GridExportExcelMLRowCreatedArgs e ) 
        
            { 
        
                if ( e.RowType == GridExportExcelMLRowType.HeaderRow ) 
        
                { 
        
                    RowElement myNewRow = new RowElement(); 
        
                    CellElement myNewCell = new CellElement(); 
        
                    myNewCell.StyleValue = "myNewStyle"; 
        
                    myNewCell.MergeAcross = e.Row.Cells.Count - 1; 
        
                    //now call the hypothetical property which doesn't seem to exist... 
        
                    myNewCell.WrapText = true; 
        
                    //etc... 
        
                } 
        
            }

Thanks,

[Solved] Comma is treated as letter.

Hallo Telerik Team

I am using two radtextboxes in my login.aspx with password strength checking enabled for the second textbox. I am following this http://www.telerik.com/help/aspnet-ajax/input-textbox-pasword-strength-checker.html tutorial. The issue is that if the user enter coma it is treated as a usual letter instead of a special character. Is this intended or some inadvertent pitfall in the control?

How is get_currentlyEditedCell supposed to work?

Its name is clear. But when I run the following in the developer tools' console:

setTimeout(function(){

console.log($find("ctl00_MainContent_gv").get_batchEditingManager().get_currentlyEditedCell());

},5000);

Then get the focus to a grid cell open for editing, I get null logged after the 5 seconds elapse.

I'm creating a new functionality that requires getting the current edited cell at a keyup event handler. How to achieve this?

[Solved] set_visibleStatusbar doesn't work if RenderMode is lightweight

I have recently upgraded a project to Telerik.Web.UI.dll 2013.3.1015.40. Our RadWindows are opened through a common handler function which calls set_visibleStatusbar(false), this no longer works if I set RenderMode to auto in web.config and view in a modern browser. I have verified by manually getting a reference to the window in the browser console and calling the method directly, the status bar does not disappear.

The status bar does disappear if I set the RenderMode to classic in web.config or set VisibleStatusbar="false" in the aspx.

This seems like a bug to me, anything I might have overlooked?

Set width in javascript.

There is a radtextbox and a radsearchbox in my aspx page. The Javascript in this page has a getOrder() in which I want to access the width of the textbox and set it to searchbox using style.width. The width of searchbox increases to the stipulated width but the lens symbol position remains unchanged. If I set width in markup it works, but not in JavaScript.

Disabling the file names above the async upload

Hi Team,
I am working in RadAsyncUpload. My requirement is at a point of time I will upload only one file. While uploading the file I don't want other files to be selected or remove already selected file.

Here, I wanted to either disable the whole file name that is displayed above the inlineprogress of upload control or disable the remove button associated to the file name. Also I have to disable the select button of the control when other files are uploading to the server.

When I use the following code when the file got selected

document.getElementById("<%# RadAsyncUpload1.ClientID%>").Enabled = false;

the whole control got disabled and the file is not getting uploaded. Hope you understand my question

Thanks & Regards,
Mohan

If I set the <BatchEditingSettings EditType="Cell" /> then it works but when set to row I get the error above? Soon as I doubleClick on the row to edit. All the data loads just fine and even the Delete works. The Edit and Add New causes the error. Its like it is not putting the grid into EDIT mode when I BatchEditingSettings-OpenEditingEvent ="DblClick" ?

thanks.
