How to Efficiently Post HTML Table Data to an ADO.NET DataTable?

Transferring HTML Table Data to an ADO.NET DataTable

This guide details how to move data from an HTML table (within a View) into an ADO.NET DataTable. The key is ensuring consistent naming conventions between your HTML form controls and your data model properties.

Directly iterating through HTML table rows using a foreach loop can lead to inconsistent control naming. To ensure proper data binding, structure your control names to match your model's property access paths.

Instead of inconsistently named controls, use a naming convention that reflects your C# model access. For example, instead of using names like LeaveType, use names that mirror how you'd access the property in your C# code:

var model = new LeaveBalanceViewModel();
// Assuming LeaveDetailsList contains LeaveBalanceDetails instances
var leaveType = model.LeaveDetailsList[0].LeaveType;

Your HTML control name attributes should match the property access path without the model prefix. A for loop provides better control over this naming:

for (int i = 0; i < ... ) {
    // ... generate HTML controls with names like LeaveDetailsList[i].LeaveType ...
}

Alternatively, a more elegant solution involves using a custom EditorTemplate:

• /Views/Shared/EditorTemplates/LeaveBalanceDetails.cshtml:

@model yourAssembly.LeaveBalanceDetails
<tr><td>@Html.TextBoxFor(m => m.LeaveType)</td>
    ....
</tr>

• Main View:

<table>
    <thead> ... </thead>
    <tbody>
        @Html.EditorFor(m => m.LeaveDetailsList)
    </tbody>
</table>

• Controller (Edit Action):

public ActionResult Edit(LeaveBalanceViewModel model)
{
    // Iterate through model.LeaveDetailsList and save the items to your DataTable.
}

This approach ensures data is correctly mapped from the HTML table to your model, which can then be easily transferred to the ADO.NET DataTable. The consistent naming convention is crucial for seamless data binding.
