Ensure that the necessary JavaScript libraries are included at the top of your page. Try this:

protected void lnkbtn_Click(object sender, EventArgs e)
{
    try
    {
        LinkButton linkButton = sender as LinkButton;
        GridViewRow row = linkButton.NamingContainer as GridViewRow;
        if (row != null)
        {
            int index = row.RowIndex;

            // Get the data source bound to the GridView
            DataTable dataSource = (DataTable)GrdVsettleRecords.DataSource;
            if (index >= 0 && index < dataSource.Rows.Count)
            {
                string settlementCycleValue = dataSource.Rows[index]["SettlementCycle"].ToString();
                string perTransactionLimit = dataSource.Rows[index]["PerTransactionLimit"].ToString();

                if (settlementCycleValue == "Instant")
                {
                    ddlCycle.SelectedValue = "1";
                }
                if (settlementCycleValue == "Manual")
                {
                    ddlCycle.SelectedValue = "2";
                }
                txtTPerLinit.Text = perTransactionLimit;

                // Show the modal popup here using JavaScript/jQuery
                ScriptManager.RegisterStartupScript(this, this.GetType(), "ShowModalScript", "$('#ViewDocumentmodal').modal('show');", true);
            }
        }
    }
    catch (Exception exception)
    {
        // Handle exception
        ScriptManager.RegisterStartupScript(this, this.GetType(), "ErrorMsg", "", true);
        oExceptionManager.LogError(exception.Message, " -- In btnEdit_Click Function Settlements.aspx.cs");
        throw new Exception("Error occurred: " + exception.Message);
    }
}
