How to prevent character replacement on save event

Hello i am currently using following:

DotNetNuke 5.4.4 with Turkish Language pack installed.
Server environment have Windows Server 2003 and SQL Server Express 2008 with SQL_Latin1_General_CP1_CI_AS as server and database collation.

Most of tables store Turkish characters without converting them to Friendly or numeric code (and those are usually text box fields)
(you can check following link to understand me better)
http://webdesign.about.com/od/localization/l/blhtmlcodes-tr.htm

However, there is one thing drives me crazy. That is HTML editor. Looks like after clicking update dbo.HTMLText table stores Turkish characters with Friendly codes.

For example on my portal i can see Türkçe as Türkçe when browsing. However when viewing page source or database table called htmlText i see that all Turkish chars displayed as friendly codes. [türkçe]

I pretty suspect that this is why my search does not list all results with html content.
Also when i try to submit a page of mine to Digg, or similar social platform they simply don't recognize the text and fills some of content with question marks.

Any suggestions?

[Solved] Conditional Format Radgrid

Hi,

I would like to develop the ability to conditional format a radgrid based upon a value within a field.

My radgrid data is built on the NeedDataSource and is pretty simple. I have done a quick sweep of google for conditional formatting, but i cant seem to find a simplistic answer on how to achieve it.

This is my senario.

I have a column in the grid called "Status" i want to format the background of rows with a status of "R" to a shade of red.

All other status' need not deviate from the standard formatting.

Can some offer a bit of code or advice on how to achive this?

Many Thanks

[Solved] RadGrid with 2 GridButtonColumns

Hi,

In my current project I have a RadGrid with the following columns:
- Name of type GridBoundColumn
- Email of type GridBoundColumn
- TestEmail of type GridButtonColumn
- Mobile of type GridBoundColumn
- TestSMS of type GridButtonColumn

The web page is available on http://www.gouw.ws/RadGridWithButtons.aspx

Can you please tell me:
1. On each row,
- how to disable the TestEmail button if the Email column is empty, and
- how to disable the TestSMS button if the Mobile column is empty
2. How to process on the code behind when the TestEmail button or TestSMS button is clicked?

The ASPX is given as follows:

<telerik:RadGrid ID="radGrid" AutoGenerateColumns="false" AllowSorting="true" OnNeedDataSource="radGrid_NeedDataSource" runat="server">

<ClientSettings>

<Scrolling UseStaticHeaders="true" />

</ClientSettings>

<MasterTableView TableLayout="Fixed">

<Columns>

<telerik:GridBoundColumn DataField="Name" DataType="System.String" HeaderStyle-Width="20%" HeaderText="Name" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" AllowSorting="true" UniqueName="Name" />

<telerik:GridBoundColumn DataField="Email" DataType="System.String" HeaderStyle-Width="20%" HeaderText="Email" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" AllowSorting="true" UniqueName="Email" />

<telerik:GridButtonColumn ButtonType="PushButton" Text="Test Email" HeaderStyle-Width="5%" HeaderText="Test" HeaderStyle-HorizontalAlign="Center" CommandName="TestEmail" UniqueName="TestEmail" />

<telerik:GridBoundColumn DataField="Mobile" DataType="System.String" HeaderStyle-Width="20%" HeaderText="Mobile (SMS)" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" AllowSorting="true" UniqueName="Mobile" />

<telerik:GridButtonColumn ButtonType="PushButton" Text="Test SMS" HeaderStyle-Width="5%" HeaderText="Test" HeaderStyle-HorizontalAlign="Center" CommandName="TestSMS" UniqueName="TestSMS" />

</Columns>

</MasterTableView>

CommandItemSettings

I finally got Q3 upgrade installed and I am now trying to use the
<CommandItemSettings
                    ShowExportToWordButton="true"
                    ShowExportToExcelButton="true"
                    ShowExportToCsvButton="true"
                    ShowExportToPdfButton="true"
                    />
in my current application. Intellisense says that these are not valid attributes of the CommandItemSettings element. I have looked at your example code in your demo site and they work there just fine. I copied your code into my grid definition and it does not work. What am I doing wrong? How do I get the Command item buttons to appear in my RadGrids CommandItemDisplay area?

[Solved] Drag and click on a slider with items dont work the same

Hello

I have a slider that works great when I click on it but if I drag the slider to a position it does a postback and the selected slider item always go back to the previous position.

If I drag the slider to a position I want it to be handled just as if I click on a position.

Here is some code:

RadSlider assesmentSlider = (RadSlider)e.Item.FindControl("AssesmentSlider");

assesmentSlider.ItemType = SliderItemType.Item;

//the databinding of the slider

Vklass.IUP.MatrixAssesment assesment = ((Vklass.IUP.MatrixAssesment)e.Item.DataItem);

assesmentSlider.Items.Add(new RadSliderItem("Inget", ""));

RadSliderItem sliderItem1 = new RadSliderItem("1", assesment.Text1);

assesmentSlider.Items.Add(sliderItem1);

assesmentSlider.Items.Add(new RadSliderItem("2", assesment.Text2));

assesmentSlider.Items.Add(new RadSliderItem("3", assesment.Text3));

assesmentSlider.Items.Add(new RadSliderItem("4", assesment.Text4));

assesmentSlider.Items.Add(new RadSliderItem("5", assesment.Text5));

assesmentSlider.ViewStateMode = System.Web.UI.ViewStateMode.Enabled;

assesmentSlider.AutoPostBack = false;

//The Javascript

assesmentSlider.OnClientValueChanged = "OnClientValueChanged" + assesmentSlider.ClientID;

assesmentSlider.OnClientSlideEnd = "OnClientSlideEnd" + assesmentSlider.ClientID;

string tb1 = e.Item.FindControl("SelectedAssesmentValue").ClientID;

string hiddenvalue = e.Item.FindControl("AssesmentText0").ClientID;

string answered = e.Item.Parent.Parent.FindControl("Answered").ClientID;

string jsfunction = "function " + assesmentSlider.OnClientValueChanged + "(obj,args){\nvar val = '" + hiddenvalue + "' \n$get('" + tb1 + "').value = $get(val.slice(0, -1)+obj.get_value()).value;\nif(obj.get_value() != '0'){\n $get('" + answered + "').value = 'True';\n }else{ \n$get('" + answered + "').value = 'False';\n }\n$get('UpdateDocument').click()\n}\n"; ;

string jsfunction2 = "function " + assesmentSlider.OnClientSlideEnd + "(obj,args){\n obj.set_value=obj.get_trackPosition;\n}\n"; ;

Custom Spell APIs?

Hello,

Can the Telerik Spell control be configured to use a custom provider for providing the Spell API? For instance, can the spell control use the NHunspell API to check for suggestions and use the thesaurus?

In case you are wondering why, I'm just researching now, it might be a requirement for me to use NHunspell.

Thanks.

I am using “ Telerik.Web.UI.dll 2009.2.826.20” in my desktopmodule of DNN site. This desktop module has RadGrid which allows user to filter Records based on criteria (Username, FirstName & LastName ) specified and user can select required record from grid display.
I am getting error "'RowSelected' is undefined" or “'null' is null or not an object” while filtering the records based on criteria. These errors occur occasionally, not always. It is working perfectly some times with out above said errors.
