How to take a subset of a views Model and send the subset model

Question

How do I take a subset of a views Model and send the subset model to a partial view? I created a model, but the partial is looking for the parent model. Am I creating this secondary subset model correctly? How do I get the partial to see this secondary subset model? Parent View code (not all): @model GbngWebClient.Models.BlogPublishedByBlogIdVM @* Create a subset model to send to the partial view. *@ @{ int parentBlogId = @Model.BlogPublishedByBlogId.BlogId; int parentLikeCount = @Model.BlogPublishedByBlogId.LikeCount; int parentDisLikeCount = @Model.BlogPublishedByBlogId.DisLikeCount; bool parentDisabledBoolean = @Model.BlogPublishedByBlogId.DisabledBoolean; } class = "row" > class = "col-md-1" > @* A partial view. Sending the subset model to the partial view. *@ @Html.Partial( "_BlogLikeAndDislike" , @Model) Partial view code (not all): @* Get the parent view's values that were passed via a model. *@ class = "BlogLike fa fa-my-size fa-thumbs-up" > | @Model.LikeCount class = "BlogDisLike fa fa-my-size fa-thumbs-down" > | @Model.DisLikeCount

Hi May ViewDataDisctionary add the key value pair and send to partial view @models ViewDataDictionary @{ Model[ "LikeCount" ] = 20; Model[ "DisLikeCount" ] = 30; } @Html.Partial( "_BlogLikeAndDislike" , @Models) Thanks and regards

You can create view helper here if possible like example @helper Myhelper( int LikeCount, int DisLikeCount) { @* Get the parent view's values that were passed via a model. *@ class = "BlogLike fa fa-my-size fa-thumbs-up" > | @LikeCount class = "BlogDisLike fa fa-my-size fa-thumbs-down" > | @DisLikeCount } call this helper in view class = "row" > class = "col-md-1" > @* A partial view. Sending the subset model to the partial view. *@ @Myhelper(Model.BlogPublishedByBlogId.LikeCount,Model.BlogPublishedByBlogId.DisLikeCount)

I created a class: namespace GbngWebClient.Models { public class LikeOrDislikeVM { // Auto-implemented properties. public int BlogId { get ; set ; } public int UserId { get ; set ; } public int LikeCount { get ; set ; } public int DisLikeCount { get ; set ; } public bool LikeDisabled { get ; set ; } public bool DisLikeDisabled { get ; set ; } } } I then used that class (a new model) in the parent view and populated it with values from the parent model and passed the model to the partial view : @* Create a child 'model' variable (from the parent model's data) that will be passed to the partial view. *@ @{ // Create the variable form the LikeOrDislikeVM model. var likeOrDislikeVM = new GbngWebClient.Models.LikeOrDislikeVM(); // Set the properties on the variable. likeOrDislikeVM.BlogId = @Model.BlogPublishedByBlogId.BlogId; likeOrDislikeVM.UserId = Convert.ToInt32(Session[ "UserId" ]); likeOrDislikeVM.LikeCount = @Model.BlogPublishedByBlogId.LikeCount; likeOrDislikeVM.DisLikeCount = @Model.BlogPublishedByBlogId.DisLikeCount; likeOrDislikeVM.LikeDisabled = @Model.BlogPublishedByBlogId.LikeDisabled; likeOrDislikeVM.DisLikeDisabled = @Model.BlogPublishedByBlogId.DisLikeDisabled; } class = "row" > class = "col-md-1" > @Html.Partial( "_BlogLikeAndDislike" , likeOrDislikeVM) Then in the partial view, I called in the model: @model GbngWebClient.Models.LikeOrDislikeVM @* Use the values that were passed via a model. *@ class = "row" > class = "blogLike my-size fa fa-thumbs-up" > class = "my-size" > : @Model.LikeCount class = "my-size" > | class = "blogDisLike my-size fa fa-thumbs-down" > class = "my-size" > : @Model.DisLikeCount
