Hello,
I'm trying to have a column with a template to display a link.
The following template works: "<a href='/DevOps/SoftwareInformation/Filter/${Name}'>${Name}</a>"However, I would like to create a Html.ActionLink to directly link to the controller & action.
In my cshtml file this is how I would do it:@Html.ActionLink(linkText:"Test Filter", actionName:"Filter", controllerName:"SoftwareInformation", routeValues:new { id="Test"}, htmlAttributes:null)
However, I don't manage to translate this to a column template. Everything I try just gets translated to pure text.
This is the code I use to define the column:
model.Columns.Add(new GridColumn("Name", "Name", "string", "220px") { Template = @"Html.ActionLink(linkText:""${Name} Filter"", actionName:""Filter"", controllerName:""SoftwareInformation"", routeValues:new { id=""${Name}""}, htmlAttributes:null)"});
Any advice ?
Kind regards,
Michael
Hello Maya,
Thanks a lot for this, it works great.
One small addition I want to make: if I want to pass a routvalue to the actionlink which contains the column "${Name}" then the LinkExtensions.ActionLink encodes the string which breaks the grid functionality. This is only done on the routvalues and not on the linktext.resulting template: "<a href=\"/x/y/SoftwareFilter/%24%7BName%7D\">${Name}</a>"
I've avoided this problem by replacing that in the string created by the .ToHtmlString()
Final result:
var template = Helper.Html(Controller).ActionLink("${Name}", "SoftwareFilter", "y", new { id = "replace" }, null).ToHtmlString();column.Template = template.Replace("replace", "${Name}")
Hello Michael ,
You can refer to the following thread on how you can call the Html.ActionLink method inside your controller:
http://stackoverflow.com/questions/8331041/how-to-use-mvc-3-html-actionlink-inside-c-sharp-code
Basically once you create a HtmlHelper you can then use it to create the action link form the LinkExtensions class:
var html = new HtmlHelper(new ViewContext(controllerContext, view, vdd, tdd, new StringWriter()),
new ViewDataContainer(vdd), RouteTable.Routes);
var htmlAnchor = LinkExtensions.ActionLink(html, "Link Text", "ActionName", "Controller").ToHtmlString();
You could build the action link similarly to the one I suggested in the previous post and then pass its html string as the template of the column in your code.
Let me know if you have any questions.

Thanks for the example. However I am using C# code to set the template of a column on the GridModel and not doing it in the cshtml file. Do you have example code for that aswell ?
var model = new GridModel();model.Columns.Add(new GridColumn("Name", "Name", "string", "220px") { Template = """});
Hello Michael,
Thank you for posting in our forum.
The Template for the column you set needs to be a string. What Html.ActionLink ultimately renders on a page is html so once you define the action link you can call its ToHtmlString() method and pass the result to the Template for the column. For example:
col.For(x => x.Name).Template(@Html.ActionLink(linkText: "${Name}",actionName: "Index",controllerName:"Home").ToHtmlString());
