Hello,

We are trying to use the RadGrid like an "excel" grid, and it works fine, however when we try to loop through each cell, the "Text" property always shows up as "&nbsp". However, when we use the "ExtractValues()" method, we can get the proper values. All is fine and dandy, until we hit a column that is "ReadOnly". The ReadOnly cell does not show up in the ExtractValues variable (which makes sense), but now I am back to square one as to how to get value from the cells by UniqueName. We are using Telerik version 2009.2.826.35 (2009 Q2).

                    foreach (GridDataItem row in RadGrid1.MasterTableView.Items)         
            {         
              var cell = row["MyUniqueName"];         
              Response.Write(cell.Text); // This comes out to be "&nbsp;" each time.         
            }         

Any help in directing me in the right direction would be greatly appreciated. Thanks.

Best Regards,

Patrick

Ajax with Treeview

Hello,

I want to databind whole radTreeview from a javascript call to the server.
In fact the scenario is the fallowing :
- One Treeview which display categories and sub categories from a database
- I add a new category with an ajax request to the server (ICallbackEventHandler)
- When the server callback, I want to rebind the treeview to display added category without reload the page

I've tried on several solutions like update panel, radajaxpanel, render new treeview and return html code, radajaxmanager and ajax request, but all have failed.

RadGrid, paging, row selection, and RadTextBox issue

I've run into (what seems to be) a fairly bad bug. I've got it down into a proof-of-concept page which follows below. On the page there's a RadGrid, a button and a RadTextBox. If you select a row and click the "Click Me" button, then the selected row's index should appear in the RadTextBox. Now virtual scroll paging is enabled, so scroll to the second page, select a row, and then click "Click Me". Here I get an exception. It appears that the RadGrid has somehow forgotten it has a row selected. Moreover, if I change the RadTextBox to a native ASP.NET TextBox the crash doesn't happen.

Any input would be appreciated.

Environment: Visual Studio 2005, ASP.NET 2.0 w/ MS AJAX extension, and Telerik.Web.UI.dll version 2009.1.609.20. (I know that there is a new version of Telerik.Web.UI.dll, but I dropped in the latest version and it didn't seem to help.)

Edit: Also this crash seems to be browser dependent. I've seen it in IE6, and on IE8 in compatibility mode. In "normal" IE8 and in Firefox the crash doesn't happen. I need it to work in IE6.

Why does this Javascript inside a custom Button Function not work?

Hi all,

i have this custom Button function which works fine for me. Bu now i want to extend this function with one check. I want to check if the inserted Div already exists and stop processing.

Here is my code:

    
            Telerik.Web.UI.Editor.CommandList["Inhaltsverzeichnis"] = function(commandName, editor, args)  
        
            {  
        
              if (document.getElementById("toc")) {   
        
                alert('Es existiert bereits ein Inhaltsverzeichnis-Tag im Content-Bereich!');  
        
              }  
        
              else {   
        
                editor.pasteHtml('Inhaltsverzeichnis<br /><br /><div id="toc">-Inhaltsverzeichnis-</div><br /><br />');   
        
                alert('Inhaltsverzeichnis wurde erfolgreich hinzugefuegt!');  
        
              }  
        
            };

The div with the id = toc definitly exists, but my code always goes to the Else part of the if statement. Whats wrong?

thank you

Javascript Error when trying to use editor.pasteHtml

Hi,

i have a big Problem. I get a Javascript Error when i try to use the editor.pasteHtml Function.

Here is my Code:

ConfigFile.xml

    
            <configuration> 
        
                <property name="ToolbarMode">ShowOnFocus</property> 
        
                <property name="ToolsWidth">680px</property>    
        
                <property name="AllowScripts">true</property> 
        
            </configuration>

ToolsFile.xml

    
                <tool name="Inhaltsverzeichnis" />

MOSSEditorTools.js

    
            Telerik.Web.UI.Editor.CommandList["Inhaltsverzeichnis"] = function(commandName, editor, args)  
        
            {  
        
              alert('test');  
        
              editor.PasteHtml('Hallo!!!');   
        
            };

It is very curious! When i only call alert('test'); without editor.PasteHtml('asdasd'); finally, everything works fine and i get an alert without any errors. But when i try to use the editor.PasteHtml('hello'); function, i always get an Javascript error and nothing happens.

Can someone help please.

regards
yavuz

No AutoCompleteMode?

How come I cannot set different AutoCompleteModes in the asp version of the radcombobox?

The feature exists in radcombobox for winforms, apparently. But the available autocompletion in webpages does not deliver what I need.

Will this be added in the future?

Unable to localize Radeditor

Hi.

I've downloaded radeditor 5.5.1 trial, and successfully added to our local WSS 3.0 installation.
We can get it working, and can customize its toolbar modifying file ListToolsFile.xml.

Next step was to try to localize tooltips for the toolbar and messages: I've followed the suggestions I've found in some previous messages in this forum, and I've downloaded the file 088436_086570_it-IT_App_GlobalResources.zip; then I extracted its content in App_Globalresources folder, so I get RadEditor.Main.it-IT.resx, RadEditor.Dialogs.it-IT.resx, RadEditor.Tools.it-IT.resx and RadEditor.Modules.it-IT.resx side by side with other resources files from trial installation.
Next step was to edit ListConfigFile.xml, adding the line
<property name="Language">it-IT</property>

Anyway, strings are still in English. But if I try to alter other settings from ListConfigFile.xml, I can see the correct result in my browser (eg, I can remove Html from "EditModes" property and actually I don't see the html editor panel any longer.

So what am I doing wrong?

TIA
