I am trying to enable/disable a raddatepicker control and am unable to do so. I followed the online documentation for the client-side api and when it runs, I get the msg "radAdmitDate" is undefined.

Below is my documented code. What am I doing incorrectly?

RadComboBox inside RadWindow

Hello Sir,

We use RadComboBox inside RadWindow as the following:

<telerik:RadWindow ID="WinFirms" runat="server" Title="Select Firm" Width="500" Height="200" Behaviors="Move" VisibleStatusbar="false"

VisibleOnPageLoad="false" Modal="true" EnableShadow="true" DestroyOnClose="false" Skin="Sunset">

<ContentTemplate>

<div style="padding:10px;">

<div style="float:left; width:10px;">

Firm:

</div>

<div>

<telerik:RadComboBox runat="server" ID="ddlFirm" Width="100%" MarkFirstMatch="True" CausesValidation="false" HighlightTemplatedItems="true">

<HeaderTemplate>

<table style="width:95%" cellspacing="0" cellpadding="0" class="MultiColumnComboBox">

<tr>

<td style="width: 50px">DFSA No</td>

<td style="width: 100px">Firm Name</td>

<td style="width: 50px">Capacity</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width:100%" cellspacing="0" cellpadding="0" class="MultiColumnComboBox">

<tr>

<td style="width: 20%; color:Gray;"><%#DataBinder.Eval(Container.DataItem, "DfsaNo")%> </td>

<td style="width: 70%"><%#DataBinder.Eval(Container.DataItem, "DName")%></td>

<td style="width: 10%; color:Gray;"><%#DataBinder.Eval(Container.DataItem, "Capacity")%></td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

</div>

<div style="text-align:center;">

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Firm is required" Display="Dynamic" ControlToValidate="ddlFirm"></asp:RequiredFieldValidator>

<asp:Button runat="server" id="WinOK" OnClientClick="SubmitFirmDialog();return false;" Text="OK" UseSubmitBehavior="False" ValidationGroup="SubmitWindow" CausesValidation="true"/>

<asp:Button runat="server" id="WinCancel" OnClientClick="Hide();return false;" Text="Cancel" UseSubmitBehavior="False" />

</div>

</ContentTemplate>

</telerik:RadWindow>

We Fill DDL as following

Sub LoadFirmData()

ddlFirm.DataSource = FirmDetails.GetAfAspRaFirmByVal()

ddlFirm.DataBind()

End Sub

We set the values inside ItemDataBound even handler after binding it

Protected Sub ddlFirm_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemEventArgs) Handles ddlFirm.ItemDataBound

e.Item.Text = e.Item.DataItem.DName

e.Item.Value = e.Item.DataItem.PersonID & "%" & e.Item.DataItem.Capacity

e.Item.Attributes.Add("FirmID", e.Item.DataItem.PersonID)

e.Item.Attributes.Add("Capacity", e.Item.DataItem.Capacity)

e.Item.Attributes.Add("DfsaNo", e.Item.DataItem.DfsaNo)

End Sub

First page Load the data loads successfully and displayed inside the ComboBox.

When a callback happens the ComboBox loads all data as empty as the following HTML:

</tr>

</tbody></table>

</li>

At the same time when we assess the list items on client side we get the results of (value + attributes) correctly. But its not displayed in the dropdown.

How do I validate a field and prevent an insertion based on the result of the validation

I have a radgrid with one column called ApplicationName. When I click the "Add New Record" button to add a new record and fill out the textbox, I want to check the textbox to make sure there is not a duplicate ApplicationName in the database. How do I access the textbox to perform validation on it and what event do I place the code inside. I thought it would be the ItemCommand evnet but it seems to happen after the insert is completed.

Do you have an example? I looked at the examples on the website and could not find something to use.

Web.config content

<compilation debug="true" targetFramework="4.0">

Bold line is highlighted in red when error occurs, I had copied file Telerik.Web.UI.dll to bin.

Thanks in advance.

How to set column width in Code behind for DetailTable

Problem 1:
I have found a link on how to adjust the width of declaritive columns through code behind:
http://www.telerik.com/help/aspnet-ajax/grdusingcolumns.html

protected void RadGrid1_PreRender(object sender, System.EventArgs e)

{

foreach(GridColumn column in RadGrid1.Columns)

{

if (column.UniqueName == "BirthDate")

{

(column as GridBoundColumn).ReadOnly = true;

(column as GridBoundColumn).DataFormatString = "{0:D}";

break;

}

RadGrid1.Rebind();

}

Although, when I use rebind() as in the example, the detailtable expand button stops working in my grid. When it is clicked the grid rebinds again and the rows never expand.
How do I get the Expand to work after implementing the above code?

Problem 2: How do I set the width of the columns in the code behind for the Detailtable? Can you please provide a simple example. Is it done in the PreRender event? Will I need to rebind the Detailtable as well?

Thanks so much for your time,
Kellie

Pdf Export and file size

Hi all,

I have a grid that contains 8 charts and want to export this to pdf.
Following the thread http://www.telerik.com/community/forums/aspnet/grid/exception-on-pdf-export-from-grid.aspx, I've replaced the charts by .png images before.

So I have 8 .png - images, each of it has a file size of around 15KB.

When exporting this grid to pdf, the resulting document has 4 pages and a file size of around 4MB !!!
This is way too big.

I've checked the pdf export settigns and did not see anything like "DPI resolution" or "render quality" etc.
So: is there any possibility to render a grid that contains 120KB image data into a document less than 4MB?

I had another grid export containing only text, this one is only 9KB big...

greetings,
Bernd

btw.: I'm using RadControls for Asp .Net Ajax Q1/2009

Context Menu - Insert Exception

I have a instance where I have a calendar that groups multiple resources together. I added the context menu to the calendar for inserts. When I trigger the insert command in Week or Month view the timeslot variable loads properly based on the parameters that are passed from the client script. But when I attempt to trigger the insert command when the Day view is selected I get a IndexOutOfRangeException. Cell index out of range: 4.

The views are setup as follows:

Daily: GroupBy = Room, GroupDirection = Horizontal
Week: GroupBy = Room, GroupDirection = Vertical
Month: GroupBy = ""

Code:

    
                    Dim requestParams() As String = e.Argument.Split(Microsoft.VisualBasic.ChrW(32))  
        
                    Dim target As String = requestParams(0)  
        
                    Dim command As String = requestParams(1)  
        
                    If (target = "TimeSlot") Then  
        
                        If (command = "Insert") Then  
        
                            Dim index As String = requestParams(2)  
        
                            Dim timeSlot As ISchedulerTimeSlot = rsEvent.GetTimeSlotFromIndex(index)  
        
                            ^---Exception when in Day view---^
