Question Comments

Hi

I am using this procedure to preserve selected rows for the WPF GridControl, but as we are updating the grid with new data in a timer, the selected rows are still getting lost. Please suggest how should we modify this sample so as to preserve grid selected rows even between the updates (like same selected rows should be present after the grid is updated with new data in a separate thread). Also, We are using a NavigationStyle=Cell, so just wanted to also check if we need to change the NavigationStyle to Row for your below sample to work with grid updates?

Thanks

In this example how to avoid multiple selection of rows. Our requirement is user should not be able to select mutiple rows. only single row should be allowed ro select. Hope this clarifies our requirement.

Hello Vidhyadhar Dhumal,

We accidentally discovered that your initial post was outside the scope of our Support Center. Please accept our sincere apologies for not responding in a timely manner.
If this task is still important for you, find a couple of minutes to refer to the Q581629 thread. To implement the required selection mode, use the SelectionMode property as described in the Multiple Row Selection topic. To learn more about selection capabilities of the GridControl, refer to Selection.

The issue with losing the selection during updating the grid was discussed in Q452866, you can find all information there.

how to convert this syntaks

@model IEnumerable<CustomerViewModel>
@Html.Partial("IndexPartial", Model);

into vb syntax ?

almost forget, because in VB source code, index.cshtml still in C#, not in VBHTML

Hi,

The code would be as follows:

[VB.NET]
@ModelType IEnumerable(Of CustomerViewModel)
@Html.Partial("IndexPartial", Model)

As for the example, we will correct the syntax as soon as possible.

It sure would be nice if you would upgrade your examples to the current version of MircoSoft and DevExpress products.  When I tried to run the Example from here in VS 2013 using MVC 4, it had to convert to the current version and then I had to play with references and I finally ended up with this stack dump:

Hello,
In version V2014 14.2.4.0 this sample not work on web. It works only for combobox and not for other controls.
When i run the sample in debug mode, the existingHandler return empty string when eventName="GotFocus"
string existingHandler = control.GetClientSideEventHandler(eventName);

I like this. Does it work when using E2034,?

Hi DevExp Team,

I Have tried to implement this nice functionality, its works fine while i am running both xaf windows form and web application, from Visual Studio. However, when i deploy the windows form  application its fail.

it says.

Exception Occurs while assigning the 'DetailView, ID: BussinessClass_DetailView' view to WinWindow
Unabled To Cast object of type 'ModelDetailView' to type 'Solution.Module.IModelDetailViewHightlightFocusedLayoutItem'.

What i am missing or doing wrong? The web application works fine even deployed.

Hi,
Thanks for the example.

I think I found the problem with this example. It's not exporting the last column of the Grid.
Please correct the example to export the last column into report.

Thanks

this example works for version 2012?

Yes, this example should work with version 2012. Anyway, if you face any issues after converting this example to version 2012, please feel free to create a separate support ticket for this issue.

In ReportHelper.vb, in InitDetailsandPageheader cell.Text is set to the FieldName where I think it should really be set to the ColumnCaption to make use of the work done in GetColumnsInfo which selects the ColumnCaption to be the Caption if there is one or FieldName if there isn't.  It certainly works better for me.  This affects C#,  VB and ASPxGridView example code.
                  
cell.Width = columns(i).ColumnWidth
cell.Text = columns(i).ColumnCaption  'Better to show the Caption than the examples columns(i).FieldName
row.Cells.Add(cell

Thank you for your feedback. This example demonstrates how to generate an XtraReport from ASPxGridView, so we will not change its code now. 
Anyway, feel free to modify the code provided in this example according to your scenario. 

Hi,

Is it possible to get a VS project version of this example, using a List<T> as the data source and stripped to the core GridView to Report functionality?

Hi are there any examples of this using an xpcollection of xpobjects as the datasource?

Hello Johnathon ,

To process your recent post more efficiently, I created a separate ticket on your behalf: T193371: Unbound column - how to use with XPCollection. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.

Hi, I tried implementing this but the method gridView1_CustomUnboundColumnData is never triggered with IsSetData = true.
Only IsGetData is triggered.
In this regard, I found https://www.devexpress.com/Support/Center/Question/Details/CB65344
So, is this sample not correct or is there a way to get the IsSetData to work?

ClientInstanceName is missing from the ASPxMemo in the sample code. It should be:

 <dx:ASPxMemo ID="memo" runat="server" Height="71px" Width="170px" ClientInstanceName="memo">
<ClientSideEvents Init="memo_OnInit" KeyDown="memo_OnKeyDown" />

Besides lots of errors on this script, it will allow to type lowercase 'z' and numbers with the Numeric Pad even if maxLength has already been reached!!
I have changed it to somgething like:
     function memo_OnKeyDown(s, e) {
           if (s.GetText().length >= se.GetNumber())
               CorrectTextWithDelay();
           // Ctrl + V
           if (e.htmlEvent.keyCode === 86 && e.htmlEvent.ctrlKey)
               CorrectTextWithDelay();
       }

I've changed the script so the maxLength value does not get taken from the SpinEdit control, but from a variable. I've also make use of the s parameter to target the sender instead of using the ClientInstanceName value:

       var memoMaxLength = 1000;

       function memo_OnKeyDown(s, e) {
           if (s.GetText().length >= memoMaxLength)
               CorrectTextWithDelay(s);
           // Ctrl + V
           if (e.htmlEvent.keyCode === 86 && e.htmlEvent.ctrlKey)
               CorrectTextWithDelay(s);
       }

       function memo_OnInit(s, e) {
           var input = s.GetInputElement();
           if (ASPxClientUtils.opera)
               input.oncontextmenu = function () { return false; };
           else
               input.onpaste = function () { CorrectTextWithDelay(s); };
       }

       function CorrectTextWithDelay(s) {
           setTimeout(function () { s.SetText(s.GetText().substr(0, memoMaxLength)); }, 0);
       }
