Column Headers add space in front of capital letters?

This is the first I have run into this. Is there a way to turn the behavior off? Grid is populated with needdatasource event.

If a column name in my datatable is "SuperMan", the column header in the grid is displayed as "Super Man" (note the space in front of "M"). If the column name in my database is "superman" then the column header in the grid is "superman". Is there some option where I can turn off renaming my column headers? We capitalize for readability, but need the names to stay in tact so users can do excel lookups.

This particular page returns a variety of different datatables with different formats, most approx 50 columns wide so my preference is to not build lots of pages with predefined column headers to work around this.

Thanks!

Make column value/item clickable with aim to open a new panel

Hi,
how to make a column value/item clickable and when column value/item clicked open up a new ajax panel in same web page?

Scanario:

A radgrid will be loaded with data and visualized in AjaxPanel1¨
Then user clicks a column value/item (ID) for having more information about this row item/value
Then more detailed information about clicked row item/value should be loaded and visualized in AjaxPanel2

All tips/advices for a solution (code) are highly appreciated. I will load data in step 2 and 3 with sql queries. Links to demos and examples are also highly appreciated.

I would prefer to trigger an event when click the column value/item and have the instructions (=code) for action in code behind file. I will also have the column value/item as a link button because in some cases I want two different columns in radgrid that trigger different actions.

Thx in advance!

Disable Client click

Hi,

In Telerik Rad Scheduler, when a users wants to schedule an appointment, he is allowed to do only once. He has to be disabled from entering again. He can re-schedule again after deleting the first one.
I used the code :
function OnClientAppointmentInserting(sender, agrs) {
if (sender.get_appointments().get_count() >= 1)
{
agrs.set_cancel(true);
alert("Sorry..!Only One appointment is allowed. To Re-Schedule, delete ur first appointment and Schedule again");
}
}
But, if another user logs into the scheduler, he too is unable to add if there is one schedule already present and his clicks are disabled.
I want this method to be applied separately for each user. It means one user one click on scheduler. Another user one clcik on scheduler irrespective of other schedules present.

Creating a grid behind my line graph

Hi,
I have a line graph and i want a grid behind it, but i don't know how to get to work, i have got the y axis to show lines going across but not the x axis.

Also is there any way of fixing what colours the lines are, so for example Company B is always red and Company A is always blue?

Thanks

Simon

[Solved] Using user control in radgrid

I am trying to insert a user control into an item template of a radgrid to display data dynamically, but I keep getting an object reference not set to an instance of an object error when it tries to set the property container.

Below is a snippet of where I am using the user control in the radgrid:

<%@ Register Src="PropertyContainer.ascx" TagName="PropertyContainer" TagPrefix="uc1" %>

<radG:RadGrid ID="employees" OnNeedDataSource="EmployeesGrid_NeedDataSource" runat="server" AutoGenerateColumns="false">

<Columns>

<radG:GridTemplateColumn>

<ItemTemplate>

<uc1:PropertyContainer ID="PropertyContainer" runat="server" />

</ItemTemplate>

</radG:GridTemplateColumn>

</Columns>

Below is a snippet of the code behind:

protected void Page_Load(object sender, EventArgs e)

{

public void EmployeesGrid_NeedDataSource(object source, Telerik.WebControls.GridNeedDataSourceEventArgs e)

{

foreach (Employee emp in Employees)

{

PropertyContainer.SetProperties(emp.Properties);

}

)

The employee's properties are not null, and the fields will not be editable.

Any assistance would be appreciated. Thanks.

Issue with Ipad

Hi

I know you don't support the ipad, but i am trying to make a web application that is ipad browser friendly. The tooltip control is perfect for creating small menu which when the user clicks (rather than hovers) produces a menu very similar to the built in control of the ipad.
It works perfectly in all areas except one.

At 100% zoom levels on the ipad when you tap/click the parent control the tooltip appears correctly positioned. However if you zoom in the browser above 100% then the tooltip appears far away from where you have tapped / clicked
I have the positioning set to relative to the mouse pointer.

I know that you don't support the ipad, but its clear that this touch screen browsing is going to be a big part of the future and it would be great if you could look at this small issue in your future realeases as this control works very well ont he ipad other than this.

thanks

Johnathan

iPad Scrolling

I recently upgraded to 1215.

It looks like the combobox now uses single finger scrolling instead of two finger.

Is there a reason the treeview still uses two finger scrolling?

It would be great to choose single or two finger scrolling for controls that overflow.

Thanks

[Solved] WebUserControl Edit Form in a Grid Edit Modal Pop-Up...

Hi,

First of all this topic is referenced with this topic http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-edit-command-doesnt-work.aspx in a sense of the logic of the application.

So my question is...
I read the documentation and tested the demos, everything is working as expected but when i want to close or cancel the modal pop-up (lets say i don't wanna edit, update or insert anything) the modal pop-up get stuck and cant get to close/hide it.
I intended to handle de oncancel event in the radgrid but nothing, tested if it was a browser issue and in ie8, ff3.6 and chrome-latest still get the same result.
But here is the rare thing m binding with the publi

C DataItem object and if i delete this bindings (currently getting "binded" in the page_load event of the usercontrol) everything just work as always, if a make a bind even just one it get stuck, do i forget to handle and a event?...
