Found this strange behavior after reordering of the column was done: if someone swap column 1 and 4 and enters a filter expression into column 4, column 1 will have the same filter query and radgrid will have two parts in the filterexpression: one from column 1 and one from column 4. Anyone discovered that?

make paging visible always

Good day!
I have got such a question: I have got grid and I can change page size - I can set it to 10, 20 and 50.
For example: I have 47 items in the grid. When I set page size to 50 the grid's paging becomes invisible and I can not change page size any more =((
Can I make paging always visible?

Thank you
Lina

Grid with external Edit form RadInputManager validation not failing.

I have a grid that's using a separate Edit form that has a RadInputManager to validate control values (Note: The RIM and controls are part of a user control that makes up a portion of the edit form). Most of these are standard (ASP) textboxes and the RIM is properly showing the entry cues (i.e. "Please enter text here."). However, when the form is submitted, the RIM validators (?) are not firing to show the missing/incorrect fields and are also not preventing the form from being submitted (form is being posted back with bad data).

On the server side, if I check Page.IsValid, the result is true. Previously, I had a similar issue where the RIM validation was flagging the fields as bad (i.e. showing a red outline in the offending field(s)), but was still submitting the form immediately instead of forcing the user to correct the bad data.

Here's a snippet of the RadInputManager properties that are set:

<telerik:RadInputManager id="RadInputManager1" runat="server">

<telerik:TextBoxSetting ErrorMessage="Required field." Validation-IsRequired="True"

EmptyMessage="Please type here." Validation-ValidateOnEvent="Submit" >

<TargetControls>

<telerik:TargetInput ControlID="txtFirstName" Enabled="true" />

<telerik:TargetInput ControlID="txtLastName" Enabled="true" />

<telerik:TargetInput ControlID="txtEmail" Enabled="true" />

</TargetControls>

<Validation IsRequired="True" ValidationGroup="AccountValidationGroup">

</Validation>

</telerik:TextBoxSetting>

<telerik:RegExpTextBoxSetting ErrorMessage="Please enter a valid email address."

ValidationExpression="^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$" Validation-ValidateOnEvent="Submit">

<TargetControls>

<telerik:TargetInput ControlID="txtEmail" Enabled="true" />

</TargetControls>

<Validation IsRequired="True" ValidationGroup="AccountValidationGroup"></Validation>

</telerik:RegExpTextBoxSetting>

</telerik:RadInputManager

And here is the markup for the fields themselves:

<div style="float: left; width: 50%;">

<table cellspacing="0" border="0" summary="Edit Table">

<tr>

<td align="right">

<asp:Label ID="lblFirstName" runat="server" Text="First Name" />

</td>

<td>

<asp:TextBox ID="txtFirstName" runat="server" AutoCompleteType="FirstName"

TabIndex="3" />

</td>

</tr>

<tr>

<td align="right">

<asp:Label ID="lblLastName" runat="server" Text="Last Name" />

</td>

<td>

<asp:TextBox ID="txtLastName" runat="server" AutoCompleteType="LastName"

TabIndex="4" />

</td>

</tr>

<tr>

<td align="right">

<asp:Label ID="lblEmail" runat="server" Text="Email" />

</td>

<td>

<telerik:RadTextBox ID="txtEmail" runat="server" AutoCompleteType="None"

TabIndex="9"></telerik:RadTextBox>

</td>

</tr>

</table>

</div>

Has anyone seen this issue before and/or know of a solution?

Thanks,

Jon

Bug In RadDateTimePicker _onCellClickHandler event

I am using ASP.NET AJAX Q1 2010 and I am having some issues with firefox.

Scenario:
I adopted the sample at http://www.telerik.com/community/code-library/aspnet-ajax/calendar/how-to-use-raddatepicker-with-multimonthview-calendar.aspx and used it with RadTimePicker so the idea is that for selecting date, user can use multiple month calendar and then select time. However, on firefox, if first the user selects date and then selects time, the control renders invalid date (red border with invalid image).

Diagnosis:
So I traced through the code and the problem is in the click handler for the time view..

This is telerik code:

,_onCellClickHandler:function(k){var c=Telerik.Web.UI.Calendar.Utils.FindTarget(k,this.get_id());
if(c!=null){var g=c.cellIndex;
if(navigator.userAgent.match(/Safari/)){var h=c.parentNode;
var a;
for(a=0;
a<h.cells.length;
a++){if(h.cells[a]==c){g=a;
}}}var m=this._findTime(c.parentNode.rowIndex,g);
if(m!=null){this._onCellMouseOutHandler(k);
var j=this.getTime();
if(j!=null){m.setDate(j.getDate());
m.setMonth(j.getMonth());
m.setYear(j.getYear());
}var n=new Telerik.Web.UI.TimeViewSelectingEventArgs(m,j);
var d=this.raise_clientTimeSelecting(n);
if(!d){this.setTime(m.getHours(),m.getMinutes(),m.getSeconds(),m);
......................

The problem is in the bolded line. The getYear api is depreciated and instead getFullYear should be used. as if the date is Jan 5, 2011, on firefox, getYear returns 111 and when you do m.setYear(111), m's date is something wierd.
Now why does this error no manifest in all demos and normal situation is because, in setTime method we have:

,setTime:function(c,a,e,g){var f=$find(this.get__OwnerDatePickerID());

var d;

if(Object.getType(f).getName()=="Telerik.Web.UI.RadDateTimePicker"&&!f.get_calendar()){d=g;

}else{d=f.get_selectedDate();

}if(!d){d=new Date();

}d.setHours(c);

d.setMinutes(a);

d.setSeconds(e);

in normal scenario, the if condition would be false and hence d=f.get_selectedDate(); is executed. However, since I am using http://www.telerik.com/community/code-library/aspnet-ajax/calendar/how-to-use-raddatepicker-with-multimonthview-calendar.aspx, d = g is evaluated. And future down in the code, _setHiddenValue is called which actually verifies that the selected date is between min and max and this is where it fails.

Launch a radtooltip, radalert, or a plain alert in a usercontrol?

I seem to be having an issue, I am trying to launch a tooltip, radalert, or a plain alert in a usercontrol. When the user clicks a button I do some computation and then at the end of the method I try to launch a popup if it was successful. But I've been having some issues since the usercontrol reloads itself every time the button is clicked, and I needed it to reload it self.

I've tried showing the RadTootip/Alert server side but it didn't work then I tried setting the text of a literal to javascript at the end of the method but that didn't work.

Any ideas on how to show a popup at the end of a button click method?

IE7 memory leaks with Menu and Toolbar

I have a web form that uses RadMenu and RadToolBar on a form that displays a form view of records from a table (the form fields do not use Telerik controls). As the page is refreshed to show different records, each page loads slower and slower when using IE7. If I take off the Telerik controls, there's no problem. With IE8, also no memory problem (although it's still a lot slower than my own home-grown controls). Each time the page loads, IE7 gobbles up 15-20MB of memory, until I have to kill the browser. Any plans to fix this?

Insert Binary Image - RadGrid

I am trying to insert a file (PDF/JPG/XLS) into an image field in my SQL database. Thus far whatever I do, the file is inserted as a NULL value. The GridViewDataHyperLinkColumn is part of a nested detail table. All other fields update just fine.

<asp:SqlDataSource ID="sqlGetDocs" runat="server" OnInserting="SqlGetDocs_Updating"

ConnectionString="<%$ ConnectionStrings:DBConnectionString %>"

SelectCommand="spAspGetEnrollDocs" SelectCommandType="StoredProcedure"

InsertCommand="spASPinsertClientDocDatabase"

InsertCommandType="StoredProcedure">

<SelectParameters>

<asp:SessionParameter Name="SSN" SessionField="SSN" Type="String" />

</SelectParameters>

<InsertParameters>

<asp:ControlParameter ControlID="DropDownList1" Name="Client"

PropertyName="SelectedValue" Type="String" />

<asp:Parameter Name="SSN" Type="String" />

<asp:Parameter Name="DocDesc" Type="String" />

<asp:Parameter Name="FileType" Type="String" />

<asp:Parameter Name="ImageFile" dbType="Binary" />

<asp:Parameter Name="Updated" Type="DateTime" />

<asp:Parameter Name="Comments" Type="String" />

<asp:ControlParameter ControlID="lblUserName" Name="UserID" PropertyName="Text"

Type="String" />

</InsertParameters>

</asp:SqlDataSource>

If I add the following code - I receive an error where I declare "imageBytes":

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Protected Function UpdateImageField(ByVal gridEditableItem As GridEditableItem) As Byte()

Dim bytes As Byte() = (DirectCast(gridEditableItem.EditManager.GetColumnEditor("ImageFile"), GridBinaryImageColumnEditor)).UploadedFileContent

If bytes Is Nothing OrElse bytes.Length = 0 Then

bytes = New Byte() {}

End If

Return bytes

End Function

Protected Sub SqlGetDocs_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs)

Dim imageBytes As Byte() = UpdateImageField(TryCast(RadGrid.EditItems(0), GridEditableItem))

e.Command.Parameters("@ImageFile").Value = imageBytes

End

Sub



Could someone tell me what I'm doing wrong?
