Questions on UI for ASP.NET AJAX Forum

I have a class that I use to supply the image URL for toolbars. The values are held in an XML file.

I can use this quite successfully to set the ImageUrl of the various buttons in the page's code-behind.

I'd like to be able to use the same idea for populating this property in the markup.

I thought to just write something like this ...

<telerik:RadToolBarButton Value="Add" ImageUrl='<%= IconManager.GetButton("Add") %>' />

But, it seems, you can't do that.

Is there a way around this or a way to achieve the same result?

Combobox datasource question

My datasource for my radcombobox has extra fields in it. The datasource has fields for PeriodName, PeriodStartDate and PeriodEndDate. The text in the combo is the PeriodName field. What I would like is when the user selects a period name and the form postbacks, to have a label above the combobox and have it say something like "For the Period 1/2/1010 to 1/31/2010'. How would I go about doing something like this? Thanks.

Export to Pdf from Html

Hi all,
I need help on following.

I am getting Html content from SQL database, then attaching some data to it and then rendering it on a <asp:lable.. server control.
I want my users to be able to export the rendered content to a PDF file.

1. Which Telerik control will best suit for this need? (i.e. Does telerik have a control which I can use it in place of <asp:Lable that supports export to PDF)
2. If not, is there any other way to do it?

We have telerik. I don't want to use any other 3rd party components.

Thanks in advance
Piyush

Can value or text be included in viewstate postback?

Great job Telerik on RadListBox. We have a couple homegrown alternatives to this and have been hoping you would release this type of control so we could standardize.

One of our current projects relies on multiple combinations of controls created in runtime, after init. To view these object and their values on postback, we are taking advantage of request.form in the postback and parsing the results.

    
             Dim str As String 
        
             Dim str2 As String = "" 
        
            For Each str In Request.Form 
        
               str2 += str & "  -  " & Request.Form(str) & "<br>"    
        
            Next 
        
            Response.Write(str2)

RadListbox gives us a method of tracing the users actions click by click, but it would be great if the postback could include either the text, or preferably the value, of the RadListboxItem along with the ordinal position changes. We frequently need to randomize the position of the listitems in these situations to prevent bias so we will currently need to store additional data in hidden controls for the ordinal mapping. I realize this is not standard usage of the control, but if you could add for future consideration either an ordered list of all values within Radlistbox in request.form (preferable), or include the value in the ordinal move data as it is now, it would streamline the process significantly.

The example beliw is the output of a 4 item list where the last item (3) is placed in position 0 recursively until the list is in it's original position again.

    
            QUIHereType_ClientState - {"logEntries":[{"Type":5,"Index":"3","Data":{"NewIndex":"0"}},{"Type":5,"Index":"3","Data":{"NewIndex":"0"}},{"Type":5,"Index":"3","Data":{"NewIndex":"0"}},{"Type":5,"Index":"3","Data":{"NewIndex":"0"}}],"selectedIndices":[0],"checkedIndices":[],"scrollPosition":0}

Thanks again for your excellent work with this release.

DatePicker - get_selectedDate() error

Hi,

I've got a really simple situation here that is malfunctioning for some reason..
I've got a RadDatePicker :

<telerik:RadDatePicker ID="datePicker" runat="server" (...) />

And some simple javascript that is running when I press a button:

var datePickerElem = $('#<%= datePicker.ClientID %>').get(0);

var currDate = datePickerElem.get_selectedDate();

The object is found properly, but I get the exception "Microsoft JScript runtime error: Object doesn't support this property or method" when calling get_selectedDate(). Any idea of what's wrong?

changing appearance of items dropped in combo box

I have a need to either change the forecolor or the backcolor of certain items within a combo box dropdown list. Some may need both applied. I have a default backcolor to white and a default forecolor to black. The dropdown is a list of bills. If one bill contains hazardous cargo then i want the bill number to be red instead of black letters. If the bill is no longer an active bill then i want the change the backcolor of the item to be pink instead of white. If it is an inactive hazardous bill then i want red letters and a pink background to both apply. Changing the forecolor to red is working. Changing the backcolor is not working. The backcolor ends up visually not applying to the proper row. I am setting this within the ItemsRequested event with the code below within the loop that adds the data and binds it to the combo. (attached is a sceenshot of the results, each row where the column == N then the backcolor should be pink)

string mystatus;

mystatus = lBooking.STATUS;

item.Attributes.Add(

"STATUS", mystatus);

string myhaz;

myhaz = lBooking.HazFlag;

item.Attributes.Add(

"HazFlag", myhaz);

rcboBookingNum.Items.Add(item);

if (myhaz=="Y")

{

rcboBookingNum.Items[myitemcounter].ForeColor = System.Drawing.

Color.Red;

}

if (mystatus == "N")

{

rcboBookingNum.Items[myitemcounter].BackColor = System.Drawing.

Color.Pink;

}

myitemcounter = myitemcounter + 1;

XAML CODE :

<telerik:RadComboBox ID="rcboBookingNum" runat="server" OnItemsRequested="rcboBookingNum_ItemsRequested"

EnableLoadOnDemand="True" AllowCustomText="True" DropDownWidth="555px" AutoPostBack="True"

OnSelectedIndexChanged="rcboBookingNum_SelectedIndexChanged" ShowDropDownOnTextboxClick="False"

OnClientKeyPressing="OnClientKeyPressingrcboBookingNum"

MaxHeight="150"

Width="120px" Skin="Outlook" HighlightTemplatedItems="false" EnableTheming="False"

CssClass="MainPageCellInputs ForceCaps"

MaxLength="13" TabIndex="1"

MarkFirstMatch="True">

<tr>

Booking Num

</td>

Ship Name

</td>

Status

</td>

Hazardous

</td>

</tr>

</table>

</HeaderTemplate>

<tr>

<%

# DataBinder.Eval(Container, "Text")%>

</td>

<%

# DataBinder.Eval(Container, "Attributes['ShipName']") %>

</td>

<%

# DataBinder.Eval(Container, "Attributes['STATUS']")%>

</td>

<%

# DataBinder.Eval(Container, "Attributes['HazFlag']")%>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

Toggle readonly client side and no value on postback

<script type="text/javascript">

function setReadOnly()

{

var TextBox1 = $find("<%= RadTextBox1.ClientID %>");

TextBox1._textBoxElement.readOnly = state;

}

function clearReadOnly()

{

var TextBox1 = $find("<%= RadTextBox1.ClientID %>");

TextBox1._textBoxElement.readOnly = false;

}

</script>

Using the above to toggle a textbox readonly flag. Setting back readonly = false and then entering a value into the textbox, upon postback the value is empty.

Question : How to toggle readonly flag client side and make control behave correctly upon postback?

*** Note: Here is the strange part, the control only fails (empty string) on the first postback - after that things work correctly.

More Info: On the first postback - the ReadOnly flag on the server side is false. So setting readonly to false in java-script did not update something and serverside the flag is still true. I think that why the value is empty.
