Model Validation with Multiple Grids in TabStrip Control

[Vikram]

Hi,
       I have an MVC application with a view which has a Telerik TabStrip Control. The TabStrip has 3 tabs: the First tab contains three Telerik Grids, and the other two tabs one grid each.  All The values which are being bound to the grid are being validated in the Model. Each of the grids has Edit button present in each row. After editing the fields in the grid's row when insert/ save is clicked, the model validation is supposed to be fired stopping from executing the code in the controller. The problem is that validation works only for the first grid of the first tab and not for the remaining 4 grids in the View .  Below is the code

VIEW:
 <% Html.Telerik().TabStrip()
           .Name("captabletab")
           .Items(tabstrip =>
           {
               
               tabstrip.Add()
               .Text("Tab1")
                .Content(() =>
                {%>
                    <br />
                    <span class="..."></span>
                    <br />
                    <br />
                    <div>
                        <% Html.Telerik().Grid(Model.Class1)
                        .Name("Name1")

                        .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.ImageAndText).ImageHtmlAttributes(new { style = "margin-left:0" }))
                        .DataKeys(keys => keys.Add(c => c.ID))
                        .DataBinding(binding => binding.Server()
                        .Select("...", "...")
                        .Insert("....", "CapTable", new { mode = GridEditMode.InLine, type = GridButtonType.ImageAndText })
                        .Update(".....", "CapTable", new { mode = GridEditMode.InLine, type = GridButtonType.ImageAndText })
                        .Delete("....", "CapTable", new { mode = GridEditMode.InLine, type = GridButtonType.ImageAndText })
                        )
                        .Columns(columns =>
                         {
                             columns.Bound(p => p.Col1).Width(250);

                         })

                        .Render();
                    %>
                <%});
           })
           .SelectedIndex(((int)ViewData["SelectedIndex"]))
           .Render();



My MODEL has the classes - Class1, Class2, Class3, Class4, Class5 with properties which have validation using Attributes . Sample below:

public class Class1
    {

        public int ID { get; set; }

        [DisplayName("Column1")]
        [Required(ErrorMessage = "The Column1 field is required")]
        [RegularExpression(@"\b\d+\b", ErrorMessage = "The Column1 field should be a Positive Integral Value.")]
        public int Col1{ get; set; }

        [DisplayName("Column2")]
        [StringLength(20, ErrorMessage = "The length of Column2 should be less than 20 characters.")]
        [Required(ErrorMessage = "The Column2 is Required.")]
        public string Col2{ get; set; }

Hello Vikram,

It seems to me that your question is related to our MVC suite. As it is supported by another team and questions about it are posted in another forum, if I am correct, please post your enquiry in the following forum:
