Im trying to catch the textbox element by javascript, in order to put text into it. so how to set id to the textbox ??

        <tr>
                    // Id to this textbox
            <td>@Html.TextBoxFor(item => item.OperationNo)</td>
        </tr>

and then to put text into it by JS

                            // 
   document.getElementById("Textbox id").Text= " Some text " ;

You can set ID of a textbox like this.

@Html.TextBoxFor(item => item.OperationNo, new { id = "MyId" })

OR

@Html.TextBoxFor(item => item.OperationNo, htmlAttributes: new { id = "MyId" })

Output:

<input ... id="MyId" name="OperationNo" type="text" />
