Post an HTML Table to ADO.NET DataTable

Question

I have a HTML table as below in my View:

<table id="tblCurrentYear">
    <tr>
        <td>Leave Type</td>
        <td>Leave Taken</td>
        <td>Leave Balance</td>
        <td>Leave Total</td>
    </tr>
    @foreach (var item in Model.LeaveDetailsList)
    {
        <tr>
            <td>@Html.TextBoxFor(m => item.LeaveType, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveTaken, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveBalance, new { width = "100" })</td>
            <td>@Html.TextBoxFor(m => item.LeaveTotal, new { width = "100" })</td>
        </tr>
    }
</table>

I want to iterate through all the html table rows and insert the values in ADO.NET DataTable.

Simple speaking, converting HTML Table to ADO.NET DataTable.

How to extract values from HTML Table and insert into ADO.NET DataTable?

The view is based on the following model

public class LeaveBalanceViewModel
{
    public LeaveBalanceViewModel()
    {
        this.EmployeeDetail = new EmployeeDetails();
        this.LeaveBalanceDetail = new LeaveBalanceDetails();
        this.LeaveDetailsList = new List<LeaveBalanceDetails>();
    }
    public EmployeeDetails EmployeeDetail { get; set; }
    public LeaveBalanceDetails LeaveBalanceDetail { get; set; }
    public List<LeaveBalanceDetails> LeaveDetailsList { get; set; }
}

Solution

With respect to your requirement, try this

jQuery(document).on("change", ".DDLChoices", function (e) {
    var comma_ChoiceIds = '';
    var comma_ChoicesText = '';
    $('input[class="DDLChoices"]').each(function (e) {
        if (this.checked) {
            comma_ChoiceIds = comma_ChoiceIds + $(this).val() + ',';
            comma_ChoicesText = comma_ChoicesText + $(this).parent('label').parent() + ',';
        }
    });
    $('#ChoiceIds').val(comma_ChoiceIds);
    $('#ChoiceText').val(comma_ChoicesText);
});

@using (Html.BeginForm("Actionname", "Controllername", FormMethod.Post, new { id = "frmChoices" }))
{

    @Html.HiddenFor(m => m.ChoiceText, new { @id = "ChoiceText" })
    @Html.HiddenFor(m => m.ChoiceIds, new { @id = "ChoiceIds" })
    <div class="form-group">
        <div>
            <table>
                <tr>
                    <th>Name</th>
                    <th>Selected</th>
                </tr>
                @foreach (var item in @Model.Choices)
                {
                    <tr>
                        <td> <label>@item.ChoicesText</label>    </td>
                        <td> <input class="DDLChoices" value="@item.ChoiceIds" type="checkbox" /></td>
                    </tr>
                }
            </table>
        </div>
     <input type="button" value="Submit" onclick="return ChoicesPoster.passChoices()"
    </div>
}
