Displaying image inside of tooltip with scrollbars

I have a tooltip manager with declaration:

<telerik:RadToolTipManager ID="rttmFLC"

OffsetX="1"

Width="400"

Height="400"

HideEvent="LeaveToolTip"

runat="server"

OnAjaxUpdate="OnAjaxUpdate"

RelativeTo="Element"

Position="MiddleRight"

ContentScrolling="Auto"

>

</telerik:RadToolTipManager>

In code behind I load the tooltip content. The content is comprised of an image. I have found that, if the image is taller than the tootip height, a vertical scroll bar appears. However, if the image is wider than the tooltip width, a horizontal scroll bar does not appear. I have tried this by loading a simple html <img> tag in the tootip

ContentTemplateContainer.Controls collection, as well as adding a user control with an image in it. Both ways, no horizontal scrollbar. I have also tried to set the ToolTipManager ContentScrolling to "Both" instead of "Auto". Again no, horizontal scrollbar. For the time being, I can set the image width to 100%, so that the entire image width is seen in the tooltip. However, this will obviously make it so the image doesn't appear as it actually is, but rather as a "thumbnail" of sorts. Any idea why I can't get the horizontal scrollbar to show up?

How to render the value in a templated RadGrid column in a specific culture and which RadGrid event to do this in?

I wanted to know if there is an event/method for templated RadGrid columns/items where I can specifically set the culture that a specific templated value is rendered in separately from the culture used on the rest of the page/values.

Example: The user is viewing the page in Japanese and that is the culture for the overall site, but all prices in a certain column in a RadGrid need to be listed as US prices with the $ currency while all other resources need to still be in Japanese.

For a specific datagrid and templated column, how can I set the culture that a particular column's values are rendered under?

Currently code like the following would show a price of 30 as 30¥ instead of $30. In the code behind (not declaratively), when binding occurs I need to be abel to say that the price should render in the en-US culture, en-GB, etc.

<telerik:GridTemplateColumn UniqueName="ExamplePriceArea" ReadOnly="True" HeaderText="ExamplePrice">

<ItemTemplate>

<asp:Label ID="PriceLabel" runat="server" Text='<%# Eval("Price", "{0:C}") %>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

How do I place a hidden ID column into a grid

Hi

I have created a grid with 3 columns and I am able to detect a row selection on the client side.

I want to query the row for an ID attribute, so that I can pass this ID to a server function.

I have tried using a hidden column but when I do that my call to

getCellByColumnUniqueName fails because the cell doesn't exist.

surely this is a fairly common requirement.

Checkboxes Do Not Display In IE8

I have a simple RadGrid with a GridCheckBoxColumn and a GridTemplateColumn with an asp:CheckBox in the EditItemTemplate. So every row has two checkboxes on it.

When I finished work Tuesday, these checkboxes displayed. When I next started work on the grid Thursday, they did not.

I cannot figure out why they do not display.

Points On This:
1. When I display the page containing the grid in FireFox, the checkboxes display..
2. When I use View Source to save the HTML of the page that is not displaying the checkboxes and then I open that page in IE8, the checkboxes display.
3. In the debugger in the code behind, the visible property of the asp:checkbox is true.
4. I put an asp:textbox in the same EditItemTemplate as the asp:checkbox and the asp:textbox displays.

5. In the debugger on the client, I can see that the width of the asp:checkbox is set to 0. I tried manually changing the width in the debugger - it seemed to work but when I rechecked the width, it was still 0.

The HTML sent to the browser for the two columns is the following:

<td style="width:80px;">

<input id="RadGrid1_ctl00_ctl04_ctl00" type="checkbox" name="RadGrid1$ctl00$ctl04$ctl00" onclick="SelectDeselectRow(0, this);" />

</td>

<td style="width:80px;">

<span style="display:inline-block;width:50px;">

<input id="RadGrid1_ctl00_ctl04_chkSelected_2" type="checkbox" name="RadGrid1$ctl00$ctl04$chkSelected_2" />

</span>

<input name="RadGrid1$ctl00$ctl04$txtSelected_2" type="text" value="1" id="RadGrid1_ctl00_ctl04_txtSelected_2" onclick="SelectDeselectRow_2(0);" style="width:30px;" />

</td>

The best idea I have on what is happening is that there a script (generated by the RadGrid or by ASP.Net) that runs after the page is loaded that sets the width to 0, causing the checkbox to not be visible. And that this script only runs in IE8. I have looked at the script at the end of the page (which I believe is where the registered scripts go) and do not see anything that looks suspicious.

Anyone have any ideas on why the checkboxes do not display?

Thanks,

John

Grid inside Combobox

Hi,

I am using grid inside combobox. Grid has the grouping and the pager. The scenario is when user selects the item of the group the selected item value is set, the combobox is collapsed, and the user is redirected to the specific places. However, when the user clicks on the group header or anywhere on the pager, the action must be completely ignored. Currently the combobox is collapsed with the empty selected value. Could you please help me to achieve the desire behavior?

Thank you,

Tatiana

P.S. I am using v. 2009 Q3

OnClientAppointmentMoveEnd

Hi,
I am using OnClientAppointmentMoveEnd to determine if the user is trying to move an appointment to a disabled timeslot:

function onAppointmentMoveEnd(sender, args) {

var start = args.get_targetSlot().get_startTime();

var end = new Date(start.getTime() + args.get_appointment().get_duration());

var slotElement = $telerik.$(args.get_targetSlot().get_domElement());

if (slotElement.is(".Disabled") || slotElement.parent().is(".Disabled")) {

// Prevent appointment move to disabled timeslots.

alert("This venue is not available in this time period.");

args.set_cancel(true);

}

warnIfOccupied(start, end, sender, args);

}

It runs without an error but it also skips over the conditional statement when it shouldn't.

I can verify that this works when I use it on the event OnClientAppointmentResizeEnd. This code works correctly and stops the user dragging the appointment into a disabled area:

function onAppointmentResizeEnd(sender, args) {

var start = args.get_appointment().get_start();

var end = args.get_targetSlot().get_endTime();

warnIfOccupied(start, end, sender, args);

var slotElement = $telerik.$(args.get_targetSlot().get_domElement());

if (slotElement.is(".Disabled") || slotElement.parent().is(".Disabled")) {

// Prevent appointment move to disabled timeslots.

alert("This venue is not available in this time period.");

args.set_cancel(true);

}

It seems that the (slotElement.is(".Disabled") || slotElement.parent().is(".Disabled")) is not available to the OnClientAppointmentMoveEnd event.

Please advise if I am simply "doing it wrong" or, if this is in fact, a bug.

Thanks.

Confirm before delete

Hi,

I'm using a grid and I followed this demo to make a context menu wich allow to add, edit or delete a user. The problem is that I want that a confirm window appears when I click on the delete item. So, I used a WindowManger.RadConfirm(), wich call a JS function. There, I verified if the paramater is true or false. If true, so it mean the user click on okay and then, with a ajaxRequest, I call a function in the code-behind who delete the user. Everything will be just find, if it wasn't for just one thing : the grid isn't automatically update and the user stay in the list even after it is delete. I had to close my window and open it again to show my grid with the correct data. I tried to do a dataRebind, but it doesn't work. Can someone tell me what to do to refresh my grid. Thanks !!!

David
