[Solved] Internal build checkbox issue on Chrome

Hi,

Using the latest internal build (June 26th I think), I get the checkbox looking too big in Chrome. It doesn't skin properly and also the box is oversized.... Simple to replicate... It looks fine in IE9.

Regards,

Jon

Event called after "remove" button appears

I'm working with a RadAsyncUpload control and currently have a javascript function attached to OnClientValidationFailed which pops up an alert with an error message.

At the time OnClientValidationFailed fires, there is a cancel button for the file that has called it rather than the remove button once it has failed validation. Is there any event that can be captured after a file has failed and the remove button has replaced the cancel button?

[Solved] How to open DIRECTLY the custom advanced insert form

got my radscheduler working fine with objectdatasource against my sql-db.

One small drawback: When i right click to add a new appointment,
it opens a basic form. there i have to click "options" to open my advanced
form. I want my advanced form opened just after click to my "add new appoinment"
context menu item, as the basic form cannot provide all required data.

how can i achieve this?
(the less java the better :-) else please be explicit)

Hi,

I'm displaying the reults in the radgrid based on the dropdown value change
for example one of my dropdown value "INS1" giving the 200 records.So in my grid i'm displaying the 200 records as 20 pages(means 10 records per page(ISSUE1.png)) and i navigated to 15th page.
after that i selected one more value "INS2" from dropdown which gives 100 records( in my grid i suppose to display the 100 records as 10 pages(means 10 records per page),like ISSUE3.png).But i not able to see the results in grid as i was on 15th page of previous selected value("INS1") results.but INS2 has 10 pages only So i not able to see the results(no results are showing(ISSUE2.png)).

Transfer only from one direction

I want to achieve the following:

I have two Listboxes, one contains available items, the other contains 'current' items. The user must be able to transfer available items into the current items' listbox, or back again to the available items' listbox, which is standard functionality, so no problem there.

HOWEVER, the current items may not be transferred into the available items' listbox, so I need a way to prevent this, but I don't see how.. Is this possible?

RadListView Shows default ItemTemplate in list even though Setting OnItemDataBound

Hey,

I call a method OnItemDatabound that loads a Control for the ItemTemplate. This works fine, however always at the top of the list the default ItemTemplate from the Markup shows?
Why is my default ItemTemplate showing in my list??
I always see the default "THIS IS THE DEFAULT TEMPLATE" at the top of my list and then the real list items display below that.
If I remove the <ItemTemplate> Then I see the contents of the EmptyDataTemplate only, and If I remove that my list becomes empty all together?

<telerik:RadListView ID="rlvJobsListPage" runat="server" ItemPlaceholderID="phJobsList" DataSourceId="objJobList"

OnItemDataBound="rlvJobsListPage_ItemDataBound" AllowCustomPaging="true" AllowPaging="true" PageSize="20" AllowSorting="True">

<LayoutTemplate>

<div id="searchList">

<div id="phJobsList" runat="server">

</div>

</LayoutTemplate>

<EmptyDataTemplate>

No records found

</EmptyDataTemplate>

<ItemTemplate>

THIS IS THE DEFAULT TEMPLATE<br />

</ItemTemplate>

</telerik:RadListView>

protected void rlvJobsListPage_ItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)

{

// Set each bound item to status "Loaded"

if (e.Item is RadListViewDataItem)

{

RadListViewDataItem thisDataItem = (RadListViewDataItem)e.Item;

Job thisListing = (Job)thisDataItem.DataItem;

//Determine which template to get from cache

Templating listingTemplate = Templating.GetTemplateForListing(thisListing.ListingTemplate);

rlvJobsListPage.ItemTemplate = Templating.Render_ITemplate(listingTemplate.TemplatePath, TemplateType.Summary, this);

e.Item.DataBind();

}
