Hi,

I am using LoadOnDemand Combo box. And I would like to set the Empty Message to a value that also appears in the items of the combobox.
When the Combobox is loaded, the EmptyMessage is shown correctly. When clicking on the dropdown the items are shown. After clicking outside the combobox and again on the dropdown arrow, the Text property of the combobox is also filled with the empty message value.

When I use an empty message that doesn't appear in the items, there is no problem.

Is there a solution for this problem?

I've added some printscreens of what happens
Picture 1: ComboBox is loaded (with EmptyMessage = "Delhaize") -> OK
Picture 2: Dropdown arrow is clicked -> OK
Picture 3: Click outside the combobox (EmptyMessage = "Delhaize") -> OK
Picture 4: Dropdown arrow is clicked (Text is automatically set equally to the EmptyMessage) -> NOT OK

Thx,
Jeff

RadAjaxManager.IsAjaxRequest problems

I am seeing an odd problem with RajAjaxManager. When I load my page clean, the page works fine. However, when I reload the page in the same session, then IsAjaxRequest is not working. It is not set to true.

Below is what I am getting:

Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '
<!DOCTYPE html PUB'.

RadGrid not showing image column when autogenerate set to true

Hi everyone,

I have been banging my head against the wall today trying to find a solution to my problem so any help is much appreciated.

I have a radGrid that I have bound to a datatable server side and this datatable contains a column(img) of type "Image" in the back end (SQL Server 2005). I have AutoGenerateColumns set to True as the application we are building is an interrogation tool to any database or table on our server, I therefore cannot add all of the columns manually. Now, when the grid is displayed, the column "img" is not shown at all.

My first question is why this is the case and is there a setting that can be changed in order for the grid to automatically display these columns? Even if there is, we have another requirement which I am unsure how to solve?

So, firstly we need the column adding to the grid, then if the DataRow has binary data in it we would like to display the word "BLOB" in the radGrid cell. If the row does not have any data then the word "blob" in lower case should be displayed. Lastly, we then need to add a click event to that cell that will fire up a new radWindow where we can display the binary data in a text field or binary editor. (Potentially even show the image and allow them to change it?).

I have attached the code for completeness sake,

Look forward to hearing your responses.

Thanks,

M

<telerik:RadGrid ID="gdData" runat="server" AllowSorting="True"

// Find out how many records have already been shown so we can work out start position

int startPos = gdData.CurrentPageIndex * gdData.PageSize;

this.GridData = DataAccess.GetData(CurrentConStr, cbTable.SelectedValue, startPos, gdData.PageSize);

gdData.VirtualItemCount = this.GridData.recordcount;

gdData.DataSource = this.GridData.Ds.Tables[0];

set_activeRow and clearActiveRow not working for me

hello everyone :)

under which circumstances are the client-side js methods set_activeRow and clearActiveRow working ??

i tried to hook up to OnRowSelected and to OnActiveRowChanged but to no success :(
When i look up the grid's dom properties, always _activeRow is emtpy (even when more than row is active/selected) and calling set_activeRow won't change that.

<ClientEvents OnGridCreated="OnGridCreated" OnRowClick="OnGridRowClick" OnRowSelected="EventTest" />

within the handler "EventTest":

sender.clearActiveRow();

var element = sender.MasterTableView.get_dataItems()[1].get_element();

sender.set_activeRow(element);

sender.repaint();

thanks for your help,
hendrik

RadWindows and UserControls

I have a 'common dialog' that I use in lots of places in my app.

Rather than define it lots of times I put it in a control and access it that way. Works a treat.

Now I need to call that common dialog from another RadWindow (we'll call it PopupPage). And I need PopupPage to execute it's own copy of a JS function when the common dialog closes.

Now, I've worked out how to do all of that.

But, the PopupPage and the common dialog have to be managed by the same RadWindowManager for it to work.

Why? Because I'm using the techniques in this documentation article to call a function in one RadWindow (common dialog) from another RadWindow (PopupPage). The problem is that my common dialog needs to find the PopupPage to execute a script on it and it does it using this code ...

var popupPage = oWnd.get_windowManager().getWindowByName(callerName);

popuPage.get_contentFrame().contentWindow.ProcessClose(args);

Now my code actually passes the name of the calling window (PopupPage) to the commondialog (as callerName) when it opens it. So knowing the window isn't a problem. The problem is that I want my commondialog to exist in a .ascx page which means that it either is managed by a different RadWindowManager or with no manager at all.

Either way, calling .get_windoiwManager().getWindowByName() isn't going to get me the results I'm looking for.

So, how do I call a a function on a page in one RadWindow from a page in another RadWindow when the 2 RadWindows are managed using different RadWindowManagers?

cannot get exclusions to work

Hi.

I am using radcompression on a .net 2 app which is also compressing viewstate into a session.

I want to exclude a page from being compressed (specifially the viewstate as it is 300k - it's a very big and silly page with 100''s of controls on).

whatever i do i cannot achieve this - the page size does nto change.

after adding

<

telerik.web.ui>

<

radCompression>

<

excludeHandlers>

<

add handlerPath="rptcurrentactivity.aspx" matchExact="false"/>

</

excludeHandlers>

</

radCompression>

</

telerik.web.ui>

into the web.config for the site, the size does not increase as i would expect. if i remove teh appbrowser file to stop copression, the page size is inclreaed by about 300k as i expect. any ideas?

[Solved] Autopostback and Load On Demand mode

Hi,

I just wanted to ask a question, when I use the combobox on demand and I select an item, all the other items disappears. I have to erase the searching textbox to retrieve all the items.

When the combox box on demand is not on autopostback mode, the items persists and the item selected is highlighted. Is it normal?

Thanks.

Paste from Word: format lost after post back

Hi all,
we are using the new RadControl Ajax Q3 2010 SP2 and found a weird issue.
These are the steps to reproduce it:

- open up the "RadControls for ASP.NET AJAX Q3 2010 SP2 Live Examples" and choose the demo called Editor/First Look
- copy some formatted text from Word: choose a mix of left/center/right aligned sentences for your convenience. I've used the text in the attached "PasteFromWordText" image
- paste to the Editor: choosing "no" (or "Cancel") to the request to clean the formatting: the text appears the same as it appears in Word: good
- click the "HTML" button to view the html code
- click the "Design" button to go back to the text: the formatting is lost and all paragraphs are now left-aligned (see attached "pasteFromWordAfterPostback image)

In our application we don't use the "HTML" mode but the same thing happens when we post the page back (for instance to save the text to our database): I can reassure that the Content property is not manipulated by our code and after the page is refreshed, the formatting is lost.

I've already set some properties in the Editor like ContentFilters="none" and StripFormattingOptions="none" but no luck.
Any ideas?

Thanks
Mauro
