PagerWithTools.png

Hi all,

I have a number of grids in my project(s). In many cases it is neccessary/helpful for users to

print the grids' content
copy to clipbord (for further analysis in e.g. Excel)
export data to a Excel readable file or PDF

I have set my sights on creating a user control containing a Radgrid (of course) and a toolbar of some sort which buttons can be enabled/disabled as needed (see attached mock-up picture where the toolbar replaces a pager's fuctionality plus has some tools). I have the feeling that this feature can be valuable to many users as it would provide a uniform approach to these common tasks.

I have be searching the forum for ideas and code snippets for my (dream) user control and I am stuck at the first stage. The print instructions in http://www.telerik.com/community/code-library/aspnet-ajax/grid/print-radgrid-contents.aspx do not work right out of the box (with or without skins).

I suspect that I am not the first one to have abovementioned need. Perhaps this functionality can already be found in some code library I have not stumbled on yet. But anyway... please point out to me the resources (complete code, snippets, problems) and might help me realize my user control.

Thank you!

Hi,

The approach which you are trying to implement in you UserControl is applicable only when exporting to PDF. Could you please elaborate more on your scenario? Providing us with more detailed information on the issue which you are facing might help us to pinpoint the reason for the unwanted behavior. I would also ask you to send us a small runnable sample in order to investigate the issue locally. Additionally I would suggest you to use a pager template in order to customize the paging then using a toolbar. The following help article demonstrates how to achieve that.

Hi Kostadin.

In essense I am trying to make a reusable grid component (user control) I can use in my projects. Generally I would like to enable the users to export to common formats (Excel, PDF) for further work, storage or printing (hard copy). Furthermore I need to add, delete and edit records in the databases. All of these are included in your CommandItemSettings. As my working languge is not English I need to translate a few display texts (sorting, pager etc.) and keep those in my reusable grid component to circumvent code duplication and tedious work. And I need more custom functions in my component.

I have therefore concluded that a toolbar embedded within the grid would be the most flexible solution. I have found a few samples http://www.telerik.com/help/aspnet-ajax/grid-commanditem-default-behavior.html http://www.telerik.com/community/code-library/aspnet-ajax/general/export-radgrid-content-to-excel-word-csv-pdf-with-ajax-enabled.aspx
and below is my extraction from these samples. It contains a lowered toolbar with three buttons and a grid (without the language stuff). This is a regular ASPX (not the user control's ASCX).

The problem sofar is that I can not get ExportToExcel button to work. It removes the paging from the grid but does not produce any output. What is wrong?

Hi Kostadin.

In my source code above I have this script:

function onToolBarClientButtonClicking(sender, args) {

var button = args.get_item();

switch (button.get_commandName()) {

case "DeleteSelected":

args.set_cancel(!confirm('Delete all selected customers?'));

break;

case "Export":

args.EnableAjax = false;

break;

}

The client-side event fires OK and EnableAJAX is changed to FALSE.

On the server-side I receive the ItemCommand event with CommandName="Export" so ExportToExcel is called.

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, _

ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

Select Case e.CommandName

Case "DeleteSelected"

If RadGrid1.SelectedIndexes.Count <> 0 Then

For Each item As GridDataItem In RadGrid1.SelectedItems

e.Item.OwnerTableView.PerformDelete(item, True)

Next

e.Item.OwnerTableView.Rebind()

End If

Case "Export"

RadGrid1.MasterTableView.ExportToExcel()

End Select

End Sub

So clicking the Export button on the grid's embedded toolbar results in

the grid is refreshed without the toolbar
the grid is without paging
I get no Excel document

What am I missing?

ToolbarEx.png

Hi Kostadin.

As you have twice referred to me the same article (Export from AJAX-enabled RadGrid) I want to underline what I am trying to do. Please look at the attached picture (similar to the one in my first post). I need grid with a toolbar (or closely associated to a grid) similar to Telerik's implementation of "commandbar" (CommandItemDisplay="top"). I need to add my own commands / shortcuts as normally on toolbars. And I would like to place the grid's title to the left on this toolbar.

Posting some code to reproduce the functionality of your "commandbar" would help.

Hello,

In order to disable the ajax you have to wire the OnRequestStart event of the ajax manager, determine whether the target control is ajaxified and explicitly disable its ajax mode to export with regular postback.

function onRequestStart(sender, args) {

if (args.get_eventTarget().indexOf("ExportButtonID") >= 0)

args.set_enableAjax(false);

}

As to the question related with the CommandItemTemplate you could check out the following live example.

Hi, Kostadin.

I still do not get it.

Clicking the Export button on the grid's embedded toolbar results in

On the client side: onToolBarClientButtonClicking is called, onRequestStart is NOT

On the server side: RadGrid1_ItemCommand is called

the grid is refreshed without the toolbar and without paging
I get no Excel document

Please CORRECT my runnable source below to get export to work by clicking the toolbar button.

AjaxifiedRadGridExport.zip

Hi,

If you debugged your sample you will noticed that the event target is not the RadToolBarButton, but it is the RadToolBar itself. So you could use the following code snippet.

function onRequestStart(sender, args) {

if (args.get_eventTarget().indexOf("RadToolBar1") >= 0) {

alert("onRequestStart: args.EnableAjax = false");

args.set_enableAjax(false);

}

Keep in mind that no matter which button you clicked inside the ToolBar the ajax will be disabled. If you want to disable the ajax only when you click the export button then you could use the following approach.
JavaScript:

<script type="text/javascript">

function disableAjax(sender, args) {

if (args.get_item().get_commandName() == "ExportExcel") {

var ajaxPanel = $find("<%= RadAjaxManager1.ClientID %>");

ajaxPanel.set_enableAJAX(false)

}

</script>

Mark-up:

<CommandItemTemplate>

<telerik:RadToolBar ID="RadToolBar1" runat="server" OnClientButtonClicked="disableAjax"

AutoPostBack="true">

<Items>

<telerik:RadToolBarButton ToolTip="Export to Excel"

CommandName="ExportExcel" Text="Export">

</telerik:RadToolBarButton>

</Items>

</telerik:RadToolBar>

</CommandItemTemplate>

Additionally I prepared a small sample based on the provided code and attached it to this forum thread.
