Somebody proposed this answer: mvccontrib grid - How to add <tr> id is there an elegant way?
I have a table like the following:
My problem
I just want to add a unique id to each row in this table
Detailed explanation of the problem
<tr class="webgrid-row-style"> I actually want @item.MvrMedsDetailsId.ToString() which is a dynamic value to be set in the row id. Like this:
<tr class="webgrid-row-style" id=@item.MvrMedsDetailsId.ToString()>
should yield for each row in the table
<tr class="webgrid-row-style" id=1>
<tr class="webgrid-row-style" id=4>
<tr class="webgrid-row-style" id=17>
The whole code
@model MedicalVariance.Models.ViewModels.AddMedicineModel
@using MedicalVariance.CustomHtmlHelpers
<script src="@Url.Content("~/Scripts/ModalEditor.js")" type="text/javascript"></script>

);//end of @grid.GetHtml()
}
Which generates the following HTML

I am sorry to disappoint you but the WebGrid helper that you are using doesn't allow you to set any other attribute on the <tr> element than the class.
Checkout the following excerpt from the ASP.NET MVC source code which is responsible for generating the <tr>:
private string GetTableBodyHtml(IEnumerable<WebGridColumn> columns, string rowStyle, string alternatingRowStyle, string selectedRowStyle)
{
StringBuilder builder = new StringBuilder();
int rowIndex = 0;
foreach (WebGridRow row in this.Rows)
{
string str = this.GetRowStyle(rowIndex, rowStyle, alternatingRowStyle, selectedRowStyle);
TagBuilder builder2 = new TagBuilder("tr");
if (!string.IsNullOrEmpty(str))
{
builder2.MergeAttribute("class", str);
}
foreach (WebGridColumn column in columns)
{
string str2 = (column.Format == null) ? HttpUtility.HtmlEncode(row[column.ColumnName]) : Format(column.Format, row).ToString();
builder2.InnerHtml = builder2.InnerHtml + GetTableCellHtml(column, str2 ?? string.Empty);
}
builder.Append(builder2.ToString());
rowIndex++;
}
return builder.ToString();
}
So your only chance is to write a completely customized helper, use another helper which gives you far more control such as MvcContrib.Grid and Telerik Mvc Grid or use javascript to append it to the DOM.
