No Data available in table

Question

Hi

  I want No Data available in table should get removed when record is added. Below is the code.

StringBuilder htmlTable = new StringBuilder();
            htmlTable.Append("<table class='table table-bordered table-hover datatable-highlight' id='tbldata'>");
            htmlTable.Append("<thead><tr style='background-color:green;color:white; text-align: center;'><th>Sr.</th><th>Document</th><th>File Name</th><th class='text-center nosort'>Action</th></tr></thead>");
            htmlTable.Append("<tbody>");
            htmlTable.Append("</tbody>");
            htmlTable.Append("</table>");
            PlaceHolderTable0.Controls.Add(new Literal { Text = htmlTable.ToString() });

document.getElementById('addRowBtn').addEventListener('click', function () {
            // Get the table body
            var tableBody = document.getElementById('tbldata').getElementsByTagName('tbody')[0];

            // Get the values from the dropdown and file upload
            var documentValue = document.getElementById('<%= ddlDocument.ClientID %>').value;
            var documentText = document.getElementById('<%= ddlDocument.ClientID %>').options[document.getElementById('<%= ddlDocument.ClientID %>').selectedIndex].text;
            var fileUpload = document.getElementById('<%= FileUploadIdentityProof.ClientID %>');
            var fileName = fileUpload.value.split('\\').pop();

            // Create a new row
            var newRow = tableBody.insertRow();

            // Insert cells and set their content
            var cell1 = newRow.insertCell(0);
            var cell2 = newRow.insertCell(1);
            var cell3 = newRow.insertCell(2);
            var cell4 = newRow.insertCell(3);

            cell1.innerHTML = tableBody.rows.length; // Sr. No.
            cell2.innerHTML = documentText; // Document
            cell3.innerHTML = fileName; // File Name
            cell4.innerHTML = '<button type="button" class="btn btn-danger btn-sm" onclick="deleteRow(this)">Delete</button>'; // Action

            // Clear the file upload control
            fileUpload.value = '';
        });

Thanks
