is it possible to get grid ID that called SaveChanges when handling grid updates in MVC?
posted

Hello - I have a solution using Asp MVC with multiple igGrids on a single page.  I am following the documentation and am getting transactions to come into my controller page when the user pushes a button that fires the SaveChanges call.  .  However, I don't get anything in the response that gives me indication on which grid / grid ID initiated the save changes event.   Was it grid #1 or grid #4?  I can change the key information of the grid to embed this information as well, but wanted to check if there is another solution so I can determine which grid is trying to save changes.   Thanks much

    Hello Andrew,

    What I can suggest in order to determine which grid triggered saveChanges is passing the grid`s id as an argument to the action method in the controller. For example:

    @(Html.Infragistics().Grid(Model)
                             .ID("grid1")
                             .Width("100%")
                             .AutoCommit(true)
                             .AutoGenerateColumns(false)
                             .PrimaryKey("ProductID")
                             .Columns(col =>
                             .Features(features =>
                              {
                                  features.Updating();
                              })
                             .UpdateUrl(Url.Action("OrdersSaveData", new {gridID = "grid1"}))
                                .DataSourceUrl(Url.Action("GetData"))
                                .Render())

    Once we the OdersSaveData method is called the grid`s id will be passed to the controller so that you can get a reference to the id and determine which grid triggered the OrdersSaveData.

    public ActionResult OrdersSaveData(string gridID)
        {
            var gridIdentifier = gridID;
            GridModel gridModel = new GridModel();
            List<Transaction<Order>> transactions = gridModel.LoadTransactions<Order>(HttpContext.Request.Form["ig_transactions"]);
            .....

    Please let me know if you need any further assistance with this mater.
