Dyanmic RadDock with user control loaded while dock expands

Hi all,

I am trying to add RadDock to my page dynamically. Inside the dock I have a RadAjaxPanel. While expanding the dock using the dock expand collapse button I am loading the user control inside the RadAjaxPanel. If I perform any postback inside the usercontrol the control disappears

If suppose if I have a RadGrid as a usercontrol with reordering columns on client property set true It doesnot work when the control is loaded inside the RadDock.

What should I do to solves these problems ?

Thanks in Advance

[Solved] Losing columns when scrolling /w frozen column and static headers

Losing the last 6 columns on a grid that has 42 columns (I know it's a lot but what can I do the user wants it like that) when I use scrolling with the 1st column frozen and static headers.

The scrolling works but I can't scroll all the way to the right so we can't see the last 6 columns, this is really a simple grid.

The 42 columns are TemplateColumns and all have a textbox in them.

At the moment I have a workaround by adding 7 bogus columns that have nothing in them. What this does is I can't see the last 6 columns but because they are fake columns I don't care.

I am using 2010.2 929 of the controls.

Please note that I currently have ticket open dated May 2008 for this issue (with a test project). Just hoping that someone has found out why this is happening when the number of columns is large (note I do not have this issue if the number of columns is like 10 or so).

Thanks as always.

[Solved] RadScheduler Docs error

On getting started page find "Using the Scheduler to manage Appointments" then scroll down to "Customizing the Scheduler". Item 2 refers to the "StartInFullTime" property. This doesn't exist anymore; it is now "ShowFullTime".

TreeView in ComboBox

hi all,
i have a grid, which the EditFormType is set to WebUserControl. On edit i need a combobox that contains a treeview, so i followed this example http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx?product=treeview

the problem is that when i select a node from the combobox it doesn't respond at the first time, i need to re-select a node again
here is my code

RadListBox and transfering templated items

I've read many posts here and elsewhere on this topic, that discuss the shenannigans people have to go through to get templates to properly render on the destination side based on whatever thing they are doing with their source RadListBox, but something I have not been able to discern, is whether or not there is any instance where a simple databound list box with no fancy components embedded in the templates can still be implemented without a postback (just client-side).

For example, given this very simple example below where I have the two RadListBoxes hooked up and I want them to show the same format in both boxes :

<telerik:RadListBox runat="server" ID="RadListBoxSource" Height="200px" Width="200px"

AllowTransfer="True" TransferToID="RadListBoxDestination" DataSourceID="SqlDataSource1"

DataValueField="USR_SEQ" DataTextField="USR_LOGINID"

SelectionMode="Multiple">

<ItemTemplate>

<div class="ld1">

<%# DataBinder.Eval(Container.DataItem, "USR_LOGINID")%></div>

<div class="ld2">

<%# DataBinder.Eval(Container.DataItem, "USR_NAME")%></div>

</ItemTemplate>

</telerik:RadListBox>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>"

SelectCommand="SELECT [USR_LOGINID], [USR_SEQ], (USR_NAME_FIRST + ' ' + USR_NAME_LAST) USR_NAME FROM [USR] order by usr_loginid">

</asp:SqlDataSource>

<telerik:RadListBox runat="server" ID="RadListBoxDestination" Height="200px" Width="200px">

<ItemTemplate>

<div class="ld1">

<%# DataBinder.Eval(Container.DataItem, "USR_LOGINID")%></div>

<div class="ld2">

<%# DataBinder.Eval(Container.DataItem, "USR_NAME")%></div>

</ItemTemplate>

</telerik:RadListBox>

What am I missing to get this to work? Does there absolutely have to be a postback to just get the second listbox to use the same template format as the first list box? Does the fact that it is a databound list force my hand? For what it is worth, I also downloaded a number of examples posted by Telerik developers and even with the post-back versions, could not get my simple example to work correctly, but I assume that is because I am missing some painfully obvious clue.

IE8 problem with the Insert Table icon in the page editor

HI,

We encountered this problem when we upgraded to IE8 on two of our three computers. The other computer has IE7 and Firefox, and it's fine with both.

- Click the Insert Table icon, which expands to a pull-down selection. The botton third of the pull-down is 3 rows of 4 table manipulation icons. With IE7 and Firefox, all 12 icons are active. With IE8, the first 10 icons are greyed out; only Set Cell Properties and Set Table Properties are active.

Bottom Line: We can't manipulate tables on our web pages.

we are woking with radeditor 2007 for ASP.net 1.0

please help!!!!!

thanks

GridMaskedColumn filtering problem

Hi all,

I have a problem with filtering by GridMaskedColumn.
This is my code:

<telerik:GridMaskedColumn DataField="Customer.PhoneNumbers" DataType="System.String"

Mask="(###) ###-####" HeaderText="Phone Number" SortExpression="Customer.PhoneNumbers"

UniqueName="CustomerPhone">

<HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="15%" />

<ItemStyle HorizontalAlign="Left" VerticalAlign="Top" Width="15%" />

</telerik:GridMaskedColumn>

The problem is:
- If I enter first three numbers in the filter field - it is filtered fine (see the screenshot ok.jpg)
- but if I enter more then three numbers or whole phone number - the filter does not work at all (see the screenshot fail1.jpg and fail2.jpg)

Any suggestions, please.
