I have a webdatagrid Infragistics NetAdvantage 2011.2 defined as follows
<asp:UpdatePanel ID="up_gridCustomers" runat="server" ChildrenAsTriggers="False" UpdateMode="Conditional"> <ContentTemplate> <ig:WebDataGrid ID="uwg_gridCustomers" runat="server" Height="300px" StyleSetName="XSALESNRO1" StyleSetPath="~/ig_res" AutoCRUD="true" Width="800px" DefaultColumnWidth="100px" AutoGenerateColumns="True"> <Behaviors> <ig:Selection RowSelectType="Single" Enabled="true" /> <ig:Paging PagerAppearance="Bottom" PageSize="50" Enabled="true" /> <ig:RowSelectors Enabled="true" RowNumbering="true" /> <ig:ColumnMoving Enabled="true" /> <ig:ColumnResizing Enabled="true" /> <ig:Filtering Alignment="Top" Visibility="Visible" Enabled="true" AnimationEnabled="true" /> <ig:Sorting SortingMode="Single" Enabled="true" /> <ig:VirtualScrolling Enabled="true" ScrollingMode="Deferred" /> </Behaviors> </ig:WebDataGrid> </ContentTemplate> </asp:UpdatePanel>
When I select a row I works perfect.
But when I select a cell and then pressed link_button any object that has a process for the server side it generates the following message
- <Errors xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

Hi edgutol,
Thank you for posting in the community.
I have tested the code you have provided using version 11.2.20112.1019 but am so far unable to replicate the described behavior. I assume that the link button you are referring is the page links. Please let me know if this is not the case.
In order to investigate this further I would appreciate a small sample page illustrating the scenario. Note that the matter may alos be related to the manipulations done to the grid server-side.
Do not hesitate to contact me if you have any questions.
Hello, I commented that we have infragistics 2011.1 and are doing a test migration to change our old components as UltraWebGrid and others that are new in version 2011.2, but in this process have a problem as the absence of double clicking a row selected and also the fact that when selecting a cell and press any object generates an error page. We are extremely concerned about the problems they had with the updates of the browsers last year and if we want to make decisions with infragistics .. I really need your help because the error that shows do not see how to fix it How do I send the code?
Please feel free to contact me if you still need assistance with this matter.
Thank you for your reply.
