The following sections have been defined but have not been rendered for the layout page "~/Views/Shared/_Layout.cshtml": "Scripts".

I put [HttpGet] Attribute above in the action. Now it's running. If anyone know the reason, just comment below. Thanks

ModelState.IsValid always false

Put this line above ModelState condition and check the values you getting for variable errors.

var errors = ModelState.Values.SelectMany(v => v.Errors);

A potentially dangerous Request.Form value was detected from the client

You can see this error everytime when you submit HTML code to the server. To avoid this set validateRequest="false" in the page and in .net 4 you need to add this <httpRuntime requestValidationMode="2.0" /> to the web.config file. Thanks Lasa

Invalid anonymous type member declarator MVC

I got this error message when i use  @data-group in ActionLink.

@Html.ActionLink(cardCategory.Name, "Index", new { controller = "Home" }, new { @class = "btn btn-default btn-lg btn-filter", @data-group = "C" })

Use an underscore _ - the Razor engine is smart enough to translate that to a data- attribute.

5. Locate the following block of code within your php.ini file:
   ; Maximum amount of memory a script may consume (128MB)
   ; http://php.net/memory-limit
   memory_limit = 32M
6. Modify the highlighted value for memory_limit as desired (example: 35M, or 40M, or 45M).
7. Click Save.

Get ASPX control value in ASCX page

Hello,

To achieve this scenario, you have to first define public property in aspx page like this.

public DropDownList AffinityGroupDDL
        {
            get
            {
                return ddlAffinityGroup;
            }
        }

After that you can access your page controls like below

var dropDownList = ((StMainDashboard)Page).AffinityGroupDDL;

Try this.
