[Solved] Can't get action link working with data bound parameter and client template

[Matthew]

In my ajax MVC grid I have the following in my detail view client template:

    <#= Id #>
    <%: Html.ActionLink("Download Last Log", "DownloadLastTestRunLogFile", "AutomationRequests", new { requestId = "<#= Id =>" }, new { @class = "button" })%> &nbsp;

The first <#= Id #> is correctly binding to the Id number, however the data binding is not working in the requestId parameter.  This is causing the template to contain the following URL: http://localhost:59269/AutomationRequests/DownloadLastTestRunLogFile?requestId=%3C%23%3D%20Id%20%3D%3E

How can I get the action link's requestId parameter to data bind?

Hi Matthew,

In this case you should manually decode the generated URL similar to the following:

Server.UrlDecode(Html.ActionLink("Download Last Log", "DownloadLastTestRunLogFile", "AutomationRequests", new { requestId = "<#=Id#>" }, new { @class = "button" }).ToHtmlString())

Also note that there is an syntax error in the template.
This 
new { requestId = "<#= Id =>" }
should be
new { requestId = "<#= Id #>" }

Ok that makes sense.

Unfortunately, after further evaluation it seems like Telerik grids are not up to the quality I need.  I am requiring a grid that is constantly updated every 15-30 seconds, and unfortunately Telerik grids cannot handle refreshes very well.  Even when data doesn't change, a refresh causes my selection to be unselected, and the detail view collapsed.  Other javascript grids I have used are smart enough to know when data comes in, that the record is already in the grid and it just needs to update it's data, not wipe all current data and recreate all the records like Telerik's grids seem to do.

Hi Matthew,

Although, not built-in, persisting selected state and detailView's expanded state can be achieved with few lines of JavaScript. I have attached a small sample which demonstrates a possible implementation.
I hope this helps.

Oh that script works perfectly.  That's easy enough.

Thanks!
