rad window and repeater

Hello, I have the following scenario:

Repeater with textbox + button that is in an AjaxPanel. When I click the button, a radWindow pops up which allows a user to make a choice based on a selection and closes. The selection gets passed back to my javascript callback function. Now I want to put the return value into the textbox in the repeater. How do I do this?

I tried hooking up an AjaxManager and the window to update txtBox in the repeater, but this doesn't work. I would just get use id of the txtBox, but looking at the page source, I can't find those text boxes, probably because their created dynamically at runtime using ajax. Any suggestions?

control disappearing

Hi,

I'm using latest version of RadGrid with a customized column with a drop down filter, just like the Google-Like filtering example.

Currently, I have the grid to get data from web service and it works really good and fast. However, if the client OnCommand event gets fired and I bind the grid again (all client side), my customized filter dropdown would disappear. Note, there's no post back on the dropdown. However, if I do make the dropdown to postback, my client side pageLoad() function gets called but it wouldn't be able to find the rad grid control.

Please help!!

Thanks,

Vic

Varying Currency Symbol

Hi,

The standard DataFormat String {0:C2} will format a number as a currency, but of course it uses the one and only currency symbol appropriate to the current culture.

When the applicaiton has multiple currencies, I would like to format amounts of money with the appropriate currency symbol.

Effectively each row of data in a dataset which has amounts in "currency" will have the appropriate currency symbol as a column/field.

I have achieved the desired result in one way - by changing the text value of the relevant cells in the ItemDataBound event handler, but this seems a little awkward. I initially wanted to modify the DataFormat string, but can't see how to get to it (it is perhaps too late in ItemDataBound).

I was just wondering whether I had a resonable approach before I start to create many different forms.

skin problem and focus error

Hi,
I have 2 problems:
1. With the tags: EnableEmbeddedSkins="false" ImagesPath="/App_Themes/Gray/Grid/" I get javascript error:
can't move focus to the control because it is invisible, not enabled or of a type that does not accept the focus.
If I remove the imagepath no error shows.

2. As you see in the print screen below, the datepicker does not find the sprite, what can that be? (I have of course included the css-file and the image, because it works for other datepickers outside of grids.)

[Solved] Using grid ItemCommand event when grid is created programmatically

Hi. I was using the ItemCommand event to handle commands on a grid that was created statically. Now that I've changed the grid to be created programmatically, commands from the grid aren't being handled. Does anyone no how I might be able to solve this?

This is part of my code:

Protected WithEvents EmployeesGrid As RadGrid

Public

Sub EmployeesGrid_ItemCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles EmployeesGrid.ItemCommand

Very slow SelectedIndexChange

I've got a sometimes very large radioButtonList which is being decorated with FormDecorator.

For some reason yesterday in IE7 when I click on a different item, it takes up to 3-4 minutes to change the selected index. This doesn't happen in Firefox. It also doesn't happen on my collegue's computer - I'm running Vista 32bit, he's running XP. The only other Vista computer in our office also has the problem.

I know that its not code-related, as I hadn't changed any code when this started happening. To be sure of it, I reverted my code to an older version, and also checked our test site which hadn't been updated in some time.

I also thought it might be a conflict with some Windows updates as my computer installed 27 of them yesterday. However, after uninstalling them all (one at a time) when I rebooted they got reinstalled anyway. *grr*

It only appears to be an issue when the radioButtonList has a lot of items in it. Also, when I remove the FormDecorator, it works as normal, even for a very large list.

Is anybody else experiencing this? Any suggestions on what is causing it?

Grid resizing after load

I have a grid with the ClientSetting AllowScroll set to true. When this is set though the grid resizes itself after page load to set it up to the correct size. This is visually quite annoying. Is there anyway to get around this?
