[Solved] Auto checkbox in Telerik Reporting

I am developing Telerik Reporting and Inside a RadGrid I have checkboxes next to the dispalyed columns. What I want is, when the report load for the first time, the first 5 checkboxes should be checked automatically. User can uncheck or select up to 8 items and on preview button click see only the items checked.
All the radgrid columns am being populated with AutoGenerateColumns="True" from stored procedure.
I have added this code and can see the checkboxes. How do I default the first 5 items as checked

<MasterTableView AllowMultiColumnSorting="true" NoMasterRecordsText="There are no data records to display.">
<Columns>
<telerik:GridTemplateColumn HeaderText="">
<ItemTemplate>
<asp:CheckBox ID="CheckBoxStatus" runat="server" AutoPostBack="true" />
</ItemTemplate>

GridDateTimeColumn date picker control doesn't show

We have a RadGrid control that is built dynamically through code in the Page's init phase.

One of the columns is a GridDateTimeColumn and the data source column is of type System.DateTime.

The problem we are having is that in the edit row (In Place editing), the datetime picker control doesn't render. It appears as a standard textbox control with no image to click to select a date.

The skin we are using is the included 'Telerik' skin, so custom skins should not be an issue. I've also tried removing the skin altogether, but that doesn't seem to work either.

The version of the rad controls we are using is 2013.2.611.40.

Anybody have any suggestions?

Thanks,

Charlie

[Solved] Formatting a CommandItemTemplate when exporting to Excel

Hello

I am using an old version of RadGrid (2008 q3) but i hope you will still be able to help me.

The grid contains a CommandItemTemplate which is exported to excel. How do i get a handle on the CommandItemTemplate before the grid is exported to apply formatting to it? Is there a way to format it using the grid's css file? However I would rather know a way for apply formatting directly in the code behind as my skin styles are not being applied to the grid on export anyhow

thanks in advance for your help

RadInputmanager dispose when RadWindow should open

Hi Telerik Team,

kind of difficult to describe, but i hope you can give me a hint...

i have a hierarchical grid, which is always in editmode.
Many dynamically generated textboxes in this grid are validated by the RadInputManager.

On a button of the page, we open a radwindow.
If the grid is opened to a deep level, we get an error when we try to open the radwindow.

TargetControls ....

protected void RadGridHierarchy_ItemCreated(object sender, GridItemEventArgs e)

{

...

TextBox tbVolumeTarget = ((TextBox)item["VolumeTarget"].Controls[0]);

NumericSetting.TargetControls.Add(new TargetInput(tbVolumeTarget.UniqueID, true));

...

RadWindow:

ButtonClick ...

RadAjaxManager.GetCurrent(Page).ResponseScripts.Add(@"OpenProfitabilitySimulation();");

JavaScript:

function OpenProfitabilitySimulation() {

var a = setTimeout('doOpenProfitabilitySimulation()', 500);

}

//Open RadWindow for profitability simulation

function doOpenProfitabilitySimulation() {

var oWnd = $find("<%=RadWindow_Create_Contract_ProfitabilitySimulation.ClientID %>");

oWnd.show();

}

With a small grid it works fine.
But when the grid gets bigger, it seems, that there is not enough time to dispose everything, before opening the window.

Following line throws the error in runtime. (NullException)

"eval.code":

$find(

'ContentPlaceHolderDefault_ContentPlaceHolderMain_ctl00_CreateContractWorkflow_3_ucCreateContract_ucContractHierarchy_RadInputManager1_NumericBehavior'

).dispose();

Possible soulutons, which are not a good option:
- it is possible to raise the Timeout, before opening the Radwindow, (but to what? The time is depends on the client. And the Grid size)
- make a complete postback and afterwards open the radwindow, That also works fine. (but clicking two buttons is not a solution)

Do you have any other ideas?
How can i wait with the window opening, until the controls have been correctly disposed?

Is it a problem of the RadInputManager?

Thanks in advance

unable to search by * in filter

I have a rad grid which allows filtering by column. Everything works fine except that in one column I have several records with values that start with "*". When I search by * I get all rows back an not the rows starting with *. If I enable linq expressions then searching by * works but then case insensitive searching no longer works.
I think RadGrid is using * as a shortcut indicator to do a "starts with" search. How can I get the filter to search for *?

Thanks,
Chris
