RadGrid Expand column appearing when it shouldn't

I have a project when one of the pages has several separate RadGrids. Each grid is bound to a generis list of custom objects, has AutoGeneratedColumns set to false, and uses GridBoundColumns to show the data.

This worked great... until we upgraded from Telerik ASP.NET 2011.1 to 2012.1.

Now this page is showing the Expand column on all grids on the page (the Expand arrows don't do anything), and for the life of me I cannot get these columns to go away. I've seen some hacks, attaching to events to remove the column or using CSS to hide the column... but the question is, why is RadGrid creating this column at all?

We've looked for properties on the RadGrid to force this off and there doesn't appear to be any. (AutoGenerateHierarchy=false doesn't do anything to help either!)

Note that there are other pages on the same site that have similar setup... multiple separate RadGrids, same settings, and so forth, and they don't exhibit the problem. I've tried to see what the difference is, and am having no luck.

Can anybody please shed some light on this question: What triggers the RadGrid to show the Expand column?

Any help is appreciated.

Get selected row in Detail table

Hi Telerik team,

I have a Hierarchical grid implemented as follows

<telerik:RadGrid ID="radGridMaster" runat="server" AutoGenerateColumns="false" OnDetailTableDataBind="radGridMaster_OnDetailTableDataBind">

<PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" />

<ClientSettings>

<Selecting AllowRowSelect="true" UseClientSelectColumnOnly="true"/>

</ClientSettings>

<MasterTableView AutoGenerateColumns="false" DataKeyNames="Name1" Name="Master">

<DetailTables>

<telerik:GridTableView Name="Detail">

<Columns>

<telerik:GridBoundColumn DataField="SubName1" SortExpression="SubName1" UniqueName="SubName1">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="SubName2" SortExpression="SubName2" UniqueName="SubName2">

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn DataField="Name1" SortExpression="Name1" UniqueName="Name1">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Name2" SortExpression="Name2" UniqueName="Name2">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

I have two buttons above the grid two move items up and down. I was able to move up and down the rows inside the Master Grid. I need to achieve the same behavior in the Details Grid.
I need to know how to access:
- The selected element from the detail grid. In Master grid I got as follow: radGridMaster.SelectedItems[0]
- The parent row of the Detail grid in the Master grid.
- The DataSource of the Detail grid. In the Master grid is radGridMaster.DataSource

Thanks in advance,

L

Custom button sizes in pager controls

My client has complained about the small target area for the "next page" button.

We are currently using the Office2010 skin.

We do not have budget to create custom skins, rather we would like to know if it is possible to make the "next page" and "previous page" buttons wider.

These are used frequently, and we have plenty of horizontal space.

Another aspect of this issue is that the buttons shift around, depending on the values of the page buttons. 1-9 is narrower than 10-19, for example, and it is not possible to click through multiple pages without moving the mouse to compensate. A wider button would provide more "wibble room".

Dynamic Client-side PanelBar not showing expandable icon

Hi,

We have our page loading the data for the panel bar items using an AJAX call, then creating the RadPanelItems dynamically using the result. We seem to be having an issue where the items don't appear to be expandable because the "arrow" icon doesn't show. This scenario works BEAUTIFULLY, with the exception that a user can't tell if root items can be opened or not ...

When we do the same thing, but completely server side, there is no issue and we see the icons correctly.

Please advise,
Kori

Obtaining grid values client side issue

Hi guys,

I've come across an issue and I was hopnig you could let me know if I'm doing something wrong or if there is a problem here.

I have a radgrid all set-up correctly. In a javascript function I need to obtain the values of the selected row, this works fine for all columns except for a column which isn't visible.

Is there a different way to retrieve values from columns where the visibility is set to false?

Newest RadDatePicker crashes code (broken functionality)

I upgrade to the latest version of Telerik (2012.2.607.40) and now my code no longer works. My control is below...

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" Culture="English (United States)" >

<Calendar UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x" ShowRowHeaders="false">

<SpecialDays>

<telerik:RadCalendarDay Repeatable="Today" ItemStyle-BorderColor="Blue">

</telerik:RadCalendarDay>

</SpecialDays>

</Calendar>

<DatePopupButton HoverImageUrl="" ImageUrl="" ToolTip="Calendar Search" />

<DateInput ID="DateInput1" runat="server" DateFormat="MM/yyyy"

DisplayDateFormat="MM/yyyy">

<ClientEvents OnFocus="Focus" OnBlur="Blur" OnValueChanging="ValueChanging" OnValueChanged="ValueChanged">

</ClientEvents>

</DateInput>

</telerik:RadDatePicker>

This is the start of my ValueChanging function...

function ValueChanging(sender, args) {

var enteredValue = args.get_newValue(); //Retrieves value as string entered or selected in calendar.

enteredValue = enteredValue.replace(/-/g, '/'); // In case user enters hyphen, change it to backslash.

After selecting a date from the calendar, the code now crashes on the replace function because get_newValue returns Wed Jun 6 00:00:00 CDT 2012, which is not a string, so it doesn't have a replace function. This used to work. Also, while digging for answers at the link below, I tried get_newDate() which I would expect to return that value instead, but it is now undefined and no longer a valid function.
